This invention relates to the fields of weaponry and insect control, and more specifically to a device for killing insects at a distance without use of toxic chemicals.
Many methods and devices have been developed for dealing with insect pests. Many people are particularly interested in dealing with flying insects as they tend to be very visible, sometimes noisy and often possessing the capability to bite or sting. Traditional means for killing flying insects include devices such as fly swatters and their equivalent or chemical sprays. The former requires a certain skill and agility to be effective and the latter leaves a potentially harmful chemical residue in the area where used. The present invention addresses these concerns and also provides entertainment to those tasked with removal of insect pests in the form of a gun designed for shooting flying insects. Other devices developed to provide insect removal in a related fashion include the following inventions.
U.S. Pat. No. 1,611,533, issued to Kirsten, is directed to an insect shooting apparatus wherein a spring-loaded pistol-type device is used to dispense a shot or bead of material in order to exterminate various household insects such as flies. The device takes the form of a gun or pistol with a piston that is operated through a linkage mechanism and released under spring actuation by means of trigger. The movement of piston in a forward direction ultimately causes release of a shot holding a nozzle from a tapered end of the barrel. A shot holding nozzle contains a liquid which when dispersed upon an insect such as a fly and exterminates same.
U.S. Pat. No. 4,653,433, issued to Comparetti is directed to a flea zapper which takes the form of a pistol and when activated by a triggered mechanism releases a powder material for controlling insects such as fleas normally found on furry animals. The flea zapper takes the form of a handgun with a pistol-type handle with a trigger to be operated by the finger of the user. When the trigger is operated, a sample of powder is released from the powder chamber through the barrel portion through an opening and dispensed onto the animal.
U.S. Pat. No. 3,791,303, issued to Sweeny et al. is directed to deterrent ammunition which takes the form of a liquid-filled hollow ball. The projectile assembly is fired from an oversized tubular barrel extension on the end of a shotgun. The projectile assembly contains deterrent ammunition which upon rupture may control flies or other insects.

While some of the objectives of the present invention are disclosed in the prior art, none of the inventions found include all of the requirements identified.
The present invention addresses all of the deficiencies of prior art bug killing gun inventions and satisfies all of the objectives described above.
(1) An improved bug killing gun providing the desired features may be constructed from the following components. A compressed gas source is provided. A chamber is provided. The chamber is fluidly connected to the compressed gas source. A barrel is provided. The barrel is located at a distal end of the chamber. A compressed gas release mechanism is provided. The release mechanism is connected to the compressed gas source. A projectile storage magazine is provided. The magazine stores particulate projectiles and is located adjacent the chamber. A projectile loading mechanism is provided. The loading mechanism moves the particulate projectiles into the chamber from the magazine. A cocking mechanism is mechanically connected to the compressed gas source, the compressed gas release mechanism, and the projectile loading mechanism. A primary automatic safety mechanism is provided. The primary safety mechanism moves to an activated position upon utilization of the cocking mechanism and moves to a deactivated position when manually deactivated by a user. The status of the primary safety mechanism is displayed by movement of a primary external safety lever from a first, safe position to a second, firing position. A stock is provided. The stock houses and supports the compressed gas source, the compressed gas release mechanism, the barrel, the chamber, the projectile storage magazine, the cocking mechanism and the projectile loading mechanism. When the gun is cocked by the cocking mechanism, the projectile loading mechanism gathers a predetermined quantity of the particulate projectiles and positions the projectiles in the chamber. When the compressed gas release mechanism is activated the projectiles are ejected from the chamber into the barrel and expelled from the gun.
(2) In a variant of the invention, a secondary safety indicator is provided. The secondary safety indicator is moved from a hidden position to a visible position by the gun cocking action and is moved to the hidden position by activation of the compressed gas release mechanism.
(3) In another variant, the compressed gas source is selected from the group that includes a prefilled CO2 cartridge, a refillable compressed gas cylinder, a pneumatically pumped gas reservoir, a spring-activated compressed gas chamber and an external compressed gas line.
(4) In still another variant, the spring-activated compressed gas chamber further includes a cylinder. The cylinder has a front end and a rear end and is fluidly connected to the chamber at the front end. A piston is provided. The piston fits sealably in the cylinder and is located within it. A compression spring is provided. The compression spring urges the piston toward the front end. A spring compression mechanism is provided. The compression mechanism urges the piston towards the rear end and compresses the compression spring. A latching mechanism is provided. The latching mechanism releasably retains the piston adjacent the rear end and retains the compression spring in a compressed state. A user performs the gun cocking action, the spring compression mechanism is operated, the piston is urged toward the rear end of the cylinder, the spring is compressed and the spring and the piston are retained by the latching mechanism until released, allowing the piston to move rapidly toward the front end of the cylinder. This provides a burst of compressed gas in the cylinder and to the connected chamber.
(5) In yet another variant, the compressed gas release mechanism further includes a trigger. The trigger is urged forward by a trigger return spring. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents release of the latching mechanism unless the cocking action is completed. The trigger has an elevating ramp located rewardly of the upper protrusion. The elevating ramp urges a releasing bracket of the latching mechanism upwardly against a downwardly urging compression spring as the trigger is moved rearwardly. The releasing bracket moves slidably within a vertical channel in the supporting stock and has a downwardly facing rib. The rib releasably engages an upwardly facing control notch in a main pole of the latching mechanism.
The main pole is attached to the piston, has an upwardly angled ramp at a rear end, located behind the control notch. The ramp guides the rib into the control notch. The main pole moves rearwardly in a channel in the supporting stock during the cocking action. The releasing bracket retains the main pole in a first, cocked position as the rib engages the control notch. The bracket releases the main pole to a second, fired position as the trigger is moved rearwardly, elevating the releasing bracket and raising the rib from the control notch. This allows the main pole and the piston to move forward as urged by the compression spring, pressurizing the cylinder.
(6) In a further variant, the projectile storage magazine further includes a conical container. The container has a circular opening at a lower end. The lower end is fitted sealably to an upper end of a vertical circular opening through the chamber. The container has a sealing lid removably or hingedly attached at an upper end.
(7) In still a further variant, the lower end of the container is fitted sealably to the upper end of said vertical circular opening through the chamber with a sealing washer.
(8) In yet a further variant, the projectile loading mechanism further includes a metering rod. The metering rod is sized and shaped to fit sealably through the vertical circular opening through the chamber and has an orthogonal activation bar extending from its lower end and a through hole located above the activation bar. The through hole is orthogonal to the bar and the metering rod and sized and located to align with the chamber when the bar is positioned against a stopping surface. The activation bar is urged upwardly by a return compression spring to rest against the lower end of the vertical circular opening in the chamber.
The through hole fills with the particulate projectiles when located above the chamber in the conical container during the cocking action. The activation bar is urged downwardly by a pivotally mounted subordination pole to rest against the stopping surface just after activation of the compressed gas release mechanism. This permits the compressed gas to eject the particulate projectiles from the chamber and through the barrel.
(9) In another variant of the invention, the projectile loading mechanism further includes a mid-chamber pipe. The pipe extends downwardly from a lower end of the magazine. A lower portion of the pipe provides a stop for one end of a return compression spring. A trajectory guide is provided. The guide is located below the lower end of the magazine, has a hollow bore sized to fit slidably about the pipe and has a vertical slot that extends downwardly from the lower end for a first predetermined distance. The slot terminates in a stopping surface. The trajectory guide is located about the pipe and provides a support platform for attachment of the projectile storage magazine. A metering rod is provided. The rod is cylindrical in shape and is sized to fit slidably within the pipe and has an orthogonal activation bar extending from its lower end. The metering rod has a through hole located above the activation bar. The through hole is orthogonal to the bar and the metering rod and is sized and located to align with the chamber when the bar is positioned against the stopping surface. The return compression spring urges the metering rod upwardly to rest against the lower end of the vertical circular opening in the chamber. A subordination pole is provided. The pole has a first end and a second end and is pivotally mounted to a cover for the compressed gas source. The first end of the subordination pole includes a metering slot. The metering slot surrounds the activation bar. The second end of the subordination pole is urged upwardly by a cam upon activation of the gas release mechanism. Upward movement of the second end of the subordination pole moves the activation bar downwardly, compresses the return compression spring and aligns the through hole of the metering rod with the chamber. This permits the compressed gas to drive the particulate projectiles out of the chamber and through the barrel. Downward movement of the second end of the subordination pole causes the activation bar to move upwardly as urged by the return compression spring. This allows the particulate projectiles to fill the through hole of the metering rod as it moves in the projectile storage magazine surrounded by the particulate projectiles.
(10) In still another variant, the spring compression mechanism further includes a primary gear rack. The gear rack is slidably located in a channel in the supporting stock, has gear teeth located upon an upper surface and has mounting fixtures adjacent a forward end for attachment of a slide handle. A reduction gear drive is provided. The gear drive is mounted to an outer cover of the cylinder. A secondary gear rack is provided. The secondary rack is attached indirectly to the piston and is located slidably in a slot in the outer cover above the reduction gear drive. The primary gear rack engages the reduction gear drive and the reduction gear drive engaging the secondary gear rack. Rearward movement of the slide handle moves the primary gear rack rearward, rotates the reduction gear drive, moves the secondary gear rack rearward and moves the piston rearward, compressing the compression spring.
(11) In yet another variant, a downward pointing cam lobe is provided. The cam lobe is located beneath and orthogonal to the metering slot. A cam activating tab is provided. The tab is located adjacent to a side edge and front end of an upper surface of the primary gear rack. The activating tab has a contoured inner surface. The contoured inner surface is sized, shaped and located to engage a front edge of the cam lobe as the primary gear rack is moved rearwardly and forwardly during operation of the cocking mechanism. Engagement of the cam lobe causes upward movement of the metering rod followed by downward movement of the metering rod during operation of the cocking mechanism. Such movement serving to dislodge any particulate projectiles adhering to the metering rod.
(12) In a further variant, engagement of the cam lobe by the cam activating tab during forward movement of the primary gear rack during operation of the cocking mechanism provides an auditory confirmation of completion of the operation.
(13) In still a further variant, a control slot, moving in concert with main pole, maintains a first end of an internal safety pivot in an elevated position during rearward movement of the control slot. This causes a second end of the pivot, which has a downward facing notch, to engage an upper protrusion at an upper end of a trigger of the compressed gas release mechanism, thereby preventing activation of the mechanism. The control slot causes downward movement of the internal safety pivot, upon completion of forward movement of the primary gear rack and the control slot. The downward movement permits release of the downward facing notch from the trigger and permits activation of the gas release mechanism.
(14) In yet a further variant, the support stock further includes a sight glass. The sight glass is positioned adjacent the magazine and permits a view of a level of the particulate projectiles contained in the magazine.
(15) In another variant, the gun uses a prefilled CO2 cartridge as a compressed gas source and the gun further includes a cylindrical cartridge chamber. The cartridge chamber is sized and shaped to enclose a CO2 cartridge and has a sealable opening at a first end for introduction of the cartridge. A concave seat located at a second end is provided. The seat is sized and shaped to fit sealably about a discharging end of the cartridge. A hollow puncturing needle is located within the seat. A sealing cap is provided. The cap is removably attached to the cartridge chamber by mating screw threads. Tightening of the cap urges the cartridge against the puncturing needle. A pressure vessel is provided. The pressure vessel is fluidly connected to a metering device. The metering device permits a predetermined charge of compressed gas to enter the chamber upon activation of the compressed gas release mechanism.
(16) In still another variant, the compressed gas release mechanism further includes a trigger. The trigger is urged forward by a trigger return spring. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents activation of the compressed gas release mechanism unless the cocking action is completed. The trigger has an elevating ramp located rewardly of the upper protrusion. The elevating ramp urges a releasing bracket of the latching mechanism upwardly against a downwardly urging compression spring as the trigger is moved rearwardly. The releasing bracket moves slidably within a vertical channel in the supporting stock and has a downwardly facing rib.
The rib releasably engages an upwardly facing control notch in a loading rod. The loading rod is urged forward by a loading coil spring, has an upwardly angled ramp at a rear end, located behind the control notch. The ramp guides the rib into the control notch.
The loading rod moves rearwardly in a channel in the supporting stock during the cocking action. The releasing bracket retains the loading rod in a first, cocked position as the rib engages the control notch. The releasing bracket releases the loading rod to a second, fired position as the trigger is moved rearwardly, elevating the releasing bracket and raising the rib from the control notch. This allows the loading rod to move forward as urged by the loading coil spring. The loading rod activates the projectile loading mechanism and the metering device.
(17) In yet another variant of the invention, the gun uses a pneumatically pumped air reservoir as a compressed gas source and the gun further includes a gas cylinder. The cylinder has an inlet valve and an outlet valve. A piston is provided. The piston fits sealably within the cylinder. A pumping mechanism is provided. The pumping mechanism is mechanically linked to the piston and moves the piston from an extended position to a compressed position within the cylinder. The inlet valve is in an open position as the piston moves from the compressed position to the extended position and is in a closed position as the piston moves from the extended position to the compressed position. The outlet valve is in a closed position as the piston moves from the compressed position to the extended position and is in an open position as the piston moves from the extended position to the compressed position.
The air reservoir is fluidly connected to the outlet valve and the chamber. The projectile loading mechanism permits a predetermined charge of compressed gas to enter the chamber upon activation of the compressed gas release mechanism. Repeated movement of the piston by the pumping mechanism from the extended position to the compressed position within the cylinder will increase pressure within the air reservoir, permitting the particulate projectiles to be ejected from the chamber with increased force upon release of the pressure by the compressed gas release mechanism.
(18) In a further variant, the compressed gas release mechanism further includes a trigger. The trigger is urged forward by a trigger return spring. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents activation of the compressed gas release mechanism unless the cocking action is completed. The trigger has an elevating ramp located rearwardly of the upper protrusion. The elevating ramp urges a releasing bracket of the latching mechanism upwardly against a downwardly urging compression spring as the trigger is moved rearwardly. The releasing bracket moves slidably within a vertical channel in the supporting stock and has a downwardly facing rib. The rib releasably engages an upwardly facing control notch in a loading rod. The loading rod is urged forward by a loading coil spring, has an upwardly angled ramp at a rear end, located behind the control notch. The ramp guides the rib into the control notch.
The loading rod moves rearwardly in a channel in the supporting stock during the cocking action. The releasing bracket retains the loading rod in a first, cocked position as the rib engages the control notch. The releasing bracket releases the loading rod to a second, fired position as the trigger is moved rearwardly, elevating the releasing bracket and raising the rib from the control notch. This allows the loading rod to move forward as urged by the loading coil spring. The loading rod activates the projectile loading mechanism.
(19) In still a further variant, the gun uses a refillable compressed gas cylinder as a compressed gas source. The cylinder has a shut off valve and an attachment fitting located adjacent a first end. A mating attachment fitting is provided. The mating fitting is mounted to the support stock and is fluidly connected to a metering device. The metering device is fluidly connected to the chamber and the metering device permits a predetermined charge of compressed gas to enter the chamber upon activation of the compressed gas release mechanism. A charged refillable compressed gas cylinder is attached to the mating attachment fitting, the shut off valve is opened and the compressed gas is released by the metering device upon activation of the compressed gas release mechanism.
(20) In yet a further variant, the compressed gas release mechanism further includes a trigger. The trigger is urged forward by a trigger return spring. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents activation of the compressed gas release mechanism unless the cocking action is completed. The trigger has an elevating ramp located rearwardly of the upper protrusion. The elevating ramp urges a releasing bracket of the latching mechanism upwardly against a downwardly urging compression spring as the trigger is moved rearwardly. The releasing bracket moves slidably within a vertical channel in the supporting stock and has a downwardly facing rib.
The rib releasably engages an upwardly facing control notch in a loading rod. The loading rod is urged forward by a loading coil spring, has an upwardly angled ramp at a rear end, located behind the control notch. The ramp guides the rib into the control notch.
The loading rod moves rearwardly in a channel in the supporting stock during the cocking action. The releasing bracket retains the loading rod in a first, cocked position as the rib engages the control notch. The releasing bracket releases the loading rod to a second, fired position as the trigger is moved rearwardly, elevating the releasing bracket and raising the rib from the control notch. This allows the loading rod to move forward as urged by the loading coil spring. The loading rod activates the projectile loading mechanism and the metering device.
(21) In another variant, the gun uses an external compressed gas line as a compressed gas source and the gun further includes an external compressed gas line. The line is connected to a compressed gas source and has a shut off valve and an attachment fitting located adjacent a first end. A mating attachment fitting is provided. The mating fitting is mounted to the support stock and is fluidly connected to a metering device. The metering device is fluidly connected to the chamber. The metering device permits a predetermined charge of compressed gas to enter the chamber upon activation of the compressed gas release mechanism. The external compressed gas line is attached to the mating attachment fitting, the shut off valve is opened and the compressed gas is released by the metering device upon activation of the compressed gas release mechanism.
(22) In still another variant, the compressed gas release mechanism further includes a trigger. The trigger is urged forward by a trigger return spring. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents activation of the compressed gas release mechanism unless the cocking action is completed. The trigger has an elevating ramp located rearwardly of the upper protrusion. The elevating ramp urges a releasing bracket of the latching mechanism upwardly against a downwardly urging compression spring as the trigger is moved rearwardly. The releasing bracket moves slidably within a vertical channel in the supporting stock and has a downwardly facing rib. The rib releasably engages an upwardly facing control notch in a loading rod. The loading rod is urged forward by a loading coil spring, has an upwardly angled ramp at a rear end, located behind the control notch. The ramp guides the rib into the control notch.
The loading rod moves rearwardly in a channel in the supporting stock during the cocking action.

The through hole 246 fills with the particulate projectiles 38 when located above the chamber 18 in the conical container 206 during the cocking action. The activation bar 238 is urged downwardly by a pivotally mounted subordination pole 262 to rest against the stopping surface 250 just after activation of the compressed gas release mechanism 30. This permits the compressed gas 138 to eject the particulate projectiles 38 from the chamber 18 and through the barrel 22.
(9) In another variant of the invention, the projectile loading mechanism 42 further includes a mid-chamber pipe 266. The pipe 266 extends downwardly from a lower end 258 of the magazine 34. A lower portion 282 of the pipe 266 provides a stop 286 for one end 290 of a return compression spring 254. A trajectory guide 298 is provided. The guide 298 is located below the lower end 258 of the magazine 34, has a hollow bore 302 sized to fit slidably about the pipe 266 and has a vertical slot 306 that extends downwardly from the lower end 258 for a first predetermined distance 308. The slot 306 terminates in a stopping surface 250. The trajectory guide 298 is located about the pipe 266 and provides a support platform 310 for attachment of the projectile storage magazine 34. A metering rod 234 is provided. The rod 234 is cylindrical in shape and is sized to fit slidably within the pipe 266 and has an orthogonal activation bar 238 extending from its lower end 242. The metering rod 234 has a through hole 246 located above the activation bar 238. The through hole 246 is orthogonal to the bar 238 and the metering rod 234 and sized and located to align with the chamber 18 when the bar 238 is positioned against the stopping surface 250. A return compression spring 254 urges the metering rod 234 upwardly to rest against a lower end 258 of the vertical circular opening 222 in the chamber 18. A subordination pole 262 is provided.
