Detailed reference will now be made to a first potential embodiment of the disclosure, which is illustrated in
The reflector 101 directs heat generated from the torch 181 towards the desired target. The reflector 101 further comprises a parabolic dish 111, a plurality of mounting bars 112, a ceramic cone 113, and a metal wrap 114. The parabolic dish 111 is the reflective device used to direct the heat generated by the torch 181. The parabolic dish 111 is a double walled parabolic reflector formed in the shape of a circular paraboloid. The parabolic dish 111 further comprises an inner wall 141 and an outer wall 142. The inner wall 141 is a made of metal and forms the heat reflecting surface of the parabolic dish 111. The outer wall 142 is a protective insulating surface that: 1) prevents heat loss in cold conditions; and, 2) prevents accidental burns from touching the inner wall 141. The outer wall 142 is made from a heat resistant insulating material such as fiber glass or poly-para-phenylene terephthalamide. The ceramic cone 113 is a ceramic structure formed in the shape of a cone. The ceramic cone 113 is mounted in the focal point of the parabolic dish 111. The ceramic cone 113 absorbs the heat generated by the torch 181 and transfers that heat back to the parabolic dish 111 for reflection. The face 143 of the ceramic cone 113 is covered in a metal wrap 114. The metal wrap 114 is a mesh formed of metal. The metal wrap 114 provides structural support for the ceramic cone 113 and distributes the heat generated from the torch 181 over the face 143 of the ceramic cone 113. The plurality of mounting bars 112 hold the ceramic cone 113 in position. Each of the plurality of mounting bars 112 is a metal bar that is further defined with a first end 161 and a second end 162. The first end 161 of each of the plurality of mounting bars 112 attaches to the edge 144 of the parabolic dish 111. The second end 162 each of the plurality of mounting bars 112 attaches to the ceramic cone 113. The second end 162 each of the plurality of mounting bars 112 can be attached directly to the ceramic cone 113 or can be attached to a locking collar that is subsequently attached to the ceramic cone 113. The plurality of mounting bars 112 further comprises a first mounting bar 115, a second mounting bar 116, a third mounting bar 117, and a fourth mounting bar 118.
The torch attachment 102 receives the torch 181 which is used to power the invention 100. The torch attachment 102 further comprises a tank connection 121, a regulator valve 122, a transport nozzle 123, a torch shroud 124 and a conical connector 125. The tank connection 121 is a screw connection which is adapted to receive the torch 181. Fuel is released from the torch 181 through the tank connection 121 and flows through the regulator valve 122. The regulator valve 122 is a commercially available threaded needle valve. The regulator valve 122 controls and regulates the flow of gas from the torch 181 into the transport nozzle 123. The transport nozzle 123 transports the gas released by the torch 181 through a nozzle hole 145 formed in the parabolic dish 111. The transport nozzle 123 is further defined with a third end 163 and a fourth end 164. The third end 163 is attached to the regulator valve 122. The fourth end 164 is open to the atmosphere within the parabolic dish 111 and releases gas from the torch 181 for use in combustion. In order to screw the torch 181 into the tank connection 121, the torch 181 is inserted into a torch shroud 124. The torch shroud 124 is a cylindrical structure that protects the torch 181 cylinder from damage.
The conical connector 125 is a hollow cone shaped structure that is used to house the torch attachment 102. The conical connector 125 further comprises a seventh end 167 and an eighth end 168. Both the seventh end 167 and the eighth end 168 are open. The seventh end 167 is at the narrow end of the cone that forms the conical connector 125. The eighth end 168 is at the broad end of the cone that forms the conical connector 125. The eighth end 168 of the conical connector 125 is attached to the outer wall 142 of the parabolic dish 111. The regulator valve 122 is mounted within the conical connector 125, however, a valve hole 146 is formed into the side of the conical connector 125 that allows a valve shaft 126 to pass through the valve hole 146 such that the valve shaft 126 can be used to operate the regulator valve 122.
The grip 103 is the handle that allows the invention 100 to be controlled and manipulated. The grip 103 further comprises a pistol grip 131, a trigger 132, an ignitor 133, a cylinder 134, a first handle 135, and a second handle 136. The structure of the grip 103 is formed from the pistol grip 131, the cylinder 134, the first handle 135 and the second handle 136. The structure of the grip 103 is formed from a heat resistant material. The grip 103 is further defined with a fifth end 165 and a sixth end 166. The pistol grip 131 is formed at the fifth end 165 of the grip 103. The pistol grip 131 is a handhold that is designed to allow the hand to wrap around the pistol grip 131 in a position similar to holding a glass or cup. The cylinder 134 is a hollow cylindrical object that creates the distance between the user and the reflector 101. The sixth end 166 of the grip 103 is attached to the seventh end 167 of the conical connector 125. A first handle 135 and a second handle 136 are attached to the cylinder 134 to allow for the use of a second hand in controlling the invention 100.
The ignitor 133 is used to start combustion of the gas flowing from the torch 181. The trigger 132 is used to initiate the ignitor 133. A commercially available trigger ignitor assembly provides both the trigger 132 and the ignitor 133. The trigger 132 is mounted near the pistol grip 131. The ignitor 133 is wired from the pistol grip 131 through the cylinder 134 and through the conical connector 125 to the fourth end 164 of the transport nozzle 123.
To use the invention 100, the regulator valve 122 is initially closed. The torch 181 is screwed into the tank connection 121. To start the use of the invention 100, the regulator valve 122 is opened and the trigger 132 is used to initiate the ignitor 133 will ignite the gas flowing from the torch 181. The regulator valve 122 is adjusted to the desired flame size. The invention 100 is then pointed towards the snow and ice that is to be melted. To discontinue use of the invention 100, the regulator valve 122 is closed.
With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention described above and in
