The invention disclosed and claimed herein deals with a heatable ice perforation device that is intended to provide for placing holes in ice in relatively quick time.
There are many advantages to being able to place holes through ice. Some are business oriented, such as drilling for various minerals and oils, placement of defense devices under the ice, and for pleasure, for example, ice fishing.
Many methods have been devised for placing holes in ice, among them, ice spuds that are manufactured from metals such as iron and steel that have one end sharpened for chopping the ice. Using one of these devices is very laborious and takes a fair amount of time to create an ice hole.
Eventually, ice augers were developed that were manipulated by hand, in that, the devices had lower ends sharpened to a cutting edge, such as blades, and the upper end was provided with a handle that was rotatable to rotate the sharp end through the ice. Using these devices is also laborious and the cutting edges need to be sharpened from time to time in order to be somewhat efficient.
A fairly significant solution to provide a less laborious device came in the form of a powered ice auger that was equipped with a sharpened lower end, but the rotatable handle was replaced with a motor, usually gas driven.
Early attempts at providing more efficient ice augers without the labor came in the form of an ice cutting device that is disclosed in U.S. Pat. No. 2,623,149, issued to Amar on Dec. 23, 1952 in which the device comprises a substantially cylindrically shaped support form of a rigid non-conducting material, that is non-electrically conducting material. The device contains an electrical heating element that is powered by a stand-alone battery.
U.S. Pat. No. 5,484,027, that issued to Greenlaw, et al on Jan. 16, 1996 deals with a device for producing a small, that is, a one-inch diameter penetration through ice quickly. The device has a conical shape made of a ceramic cone having spiral grooves that house a high resistance wire. The wire supplies heat upon being energized, the patent being silent on the source of the voltage being applied to the device in order for it to operate.
The device disclosed in U.S. Pat. No. 4,651,834, that issued Mar. 24, 1987 to Eninger, et al, deals with a chemical device for penetrating ice. The device comprises utilizing thermochemical heating by exothermic reaction between water supplied at least in part, by melting ice and a thermochemical reactant, preferable lithium and/or other alkali metal or alkali metal alloys.
Another thermochemical ice melting method can be found in U.S. Pat. No. 5,176,210, that issued on Jan. 5, 1993 to Gammon. The method directly contacts the material to be melted with a melting agent comprising at least one compound selected from the hydroxides, monoxides, methoxides and amides of the alkali metals, lithium, sodium, potassium, rubidium and cesium, or mixtures thereof.
A very complex method for penetrating ice can be found in U.S. Pat. No. 5,002,470, that issued on Jun. 11, 1991 to Andersen, et al in which an ice penetrator is delivered to the ice after having been launched from a parent vehicle. The rocket propellant of the device is the heat source for penetrating the ice.
None of the methods or devices of the above-mentioned prior art have the advantages of the instant invention device.
The invention disclosed and claimed herein deals with a heatable ice perforation device that is intended to provide for placing holes in ice in relatively quick time. The device is portable, including the required energy source and is highly efficient in perforating ice. The devices of this invention have a quiet running operation, a cleaner operation, a safer operation and an easy and efficient operation. The devices are lightweight and are therefore easier to transport than typical gas powered augers. The devices do not have gasoline engine related problems, such as messy gasoline, oil, and exhaust fumes, gas flooding, recoil rope problems or spring recoil problems, choke sticking and/or freezing, and no difficulty with spark plugs.
With more specificity, the invention deals with a heatable ice perforation device comprising in combination an elongated cylindrical housing having a top end, a bottom end, and an outside surface, wherein the elongated cylindrical housing has a second cylindrical housing supported in it. The second cylindrical housing has a top end and a bottom end and the second cylindrical housing forms a chase-way for fresh air into the device, the cylinders have a hollow opening between them forming a second chase-way for the passage of air out of the heated ice perforation device.
The bottom end of the elongated cylindrical housing has detachedly fixed thereon a power head, there being a third cylindrical housing contained within the second cylindrical housing and near the top of the second cylindrical housing.
The third cylindrical housing has a top opening and contained in the third cylindrical housing is an energy source. The energy source is connected to a heat-generating element located within the elongated cylindrical housing and near the bottom. The heat-generating element is located such that it will transfer heat contained therein to the power head.
The elongated cylindrical housing has attached to the outside surface and near the top thereof, a handle and the elongated cylindrical housing contains a control module for controlling the amount of heat generated by the energy source.
The top end of the elongated cylindrical housing and the second cylindrical housing have a common heat resistant perforated covering and the bottom end of the second cylindrical housing has a heat resistant perforated covering.
Another embodiment of this invention is a heatable ice perforation device as set forth just above wherein at least one tank is supported in the third cylindrical housing. Each tank is connected to a gas manifold regulator and the gas manifold regulator is connected to a gas transport line. The gas transport line descends to the heat-generating element. The heat-generating element is a gas ring burner. There is an igniter wire connected to an igniter on one end and the opposite end descends and is located near the gas ring burner. There is a heat resistant plate positioned at or near the bottom of and above the gas ring burner. The control module contains the igniter ignition, a gas on and off valve and a gas ring burner on and off valve.
Yet another embodiment of this invention is a method of placing holes in ice, the method comprising bringing the heatable ice perforation device as described Supra up to a temperature sufficient to melt ice, and then, applying the heated ice perforation device to the ice and maintaining the heatable ice perforation device against the ice until a hole is formed in the ice.
It is contemplated within the scope of this invention to use at least one battery within the device as an energy source to heat the device. It is also within the scope of this invention to use at least one fuel cell within the device to provide energy for the device.

The overall size of the devices of this invention may be from about 24 inches to about 48 inches in height and about 6 to fourteen inches in diameter, it being understood that the devices do not have to circular, as they may be square, rectangular, triangular, and the like.
In
For purposes of setting forth the principles of the invention, the following will be making reference to a device of this invention that is heated with propane gas using small tanks.

Housed within the housing 5 is an inner housing 9, which for most purposes, takes the same cylindrical configuration as the outside housing 5. Connectors 27 to the outer housing 5 support the inner housing 9. The inner housing 9 is smaller in diameter than the outside housing 5 so that an inner air space 10 is formed between the two housings. This air space 10 and its function will be addressed infra, but suffice it to know that this air space 10 provides an exhaust route for warm air that is generated by the heating elements (described infra) of the device 1. Towards this end, the inner housing 9 does not have a closed bottom 12 to allow the intake of cold “fresh” air into the system. Warm air from the closed bottom 8 rises upwards to exhaust through the top 13 of the device 1 through the air space 10 and out through a heat resistant wire mesh screen 14 forming the top of the device 1, that is, the entire top 13 of the device is covered by the wire screen 14. Such a configuration allows for the exhaust of warm air out through air space 10, creating a vacuum during operation that draws fresh air in and down through the inner cylinder for combustion at the propane gas ring burner 19. This wire screen 14 is removable from the device, especially when the energy source has to be replaced.
Located near the top 13 of the device 1 is a third housing 15, said housing being essentially configured according to the configuration of the inner housing 9, although, this is not critical. The third housing 15 is secured to the inner housing 9 by connectors 28. The third housing 15 is intended to hold, in this case, propane tanks 16 and 16′, and although shown as double tanks, a single tank can be used. The propane tanks are also shown in
Located adjacent the propane gas ring burner 19 is an igniter wire 20, that passes from the push button igniter 4, through the outside housing 5, through the inner housing 9, and through the wall 21 of the third housing 15 and the bottom 22 of the third housing 15 and drops to its position adjacent the propane gas ring burner 19. This igniter wire 20 is used to ignite the propane gas from the propane gas tanks 16 and 16″ within the propane gas ring burner 19. The propane gas ring burner 19 features a series of holes 26 located around its outside and bottom edges for flames to escape and heat the walls of the cup assembly of the bottom 8 to a temperature hot enough to rapidly melt through ice. Hot air rising up from the propane gas ring burner 19 keeps the wall of the outside housing 5 heated and ice free and no ice or water ever reach the propane gas ring burner 19.
Located just above the propane gas ring burner 19 is a metal, heat resistant plate 23 that is used to concentrate heat in the device's “hot Zone” before warm air is exhausted through the air space 10. To facilitate the concentration and correct movement of the warm air upwards, an opening 25 is located in the heat resistant plate.
The device of this invention is manufactured primarily from metals and preferred metals are aluminum, stainless steel, copper, and the like and aluminum and stainless steel are preferred. Most preferred is a combination of such metals to accommodate the various needs of the device 1, such as abrasion and dent resistance, heat transfer, light weight handling, ease of painting and coloring.
For example, the outer housing 5 can be manufactured from stainless steel to prevent abrasion, rusting, denting, and the like, while the bottom 8 can be manufactured from copper or aluminum, both of which have a rapid heat transfer capability. The inner housing 9 can be manufactured from aluminum to keep the weight of the device 1 lower.
To operate the device 1, one turns on the gas tanks 16 and 16′ using the gas on and off valve 2. Then the burner on and off valve 3 is turned on and the igniter button 4 is depressed to light the propane gas ring burner 19.
The device 1 is allowed to reach operating temperature (at least hot enough to melt ice) and the device 1 is placed on the ice with the cup portion of the bottom 8 against the ice. The device 1 is then held by the handle 6 while the device 1 penetrates the ice. When the ice hole is complete, the device 1 is lifted out of the hole and the gas and burner valves are turned off, or the operator continues to provide additional ice holes.
By this means, there is provided a nice smooth hole in the ice without having to remove ice shavings and chunks and the ice hole does not have any jagged edges to snag or cut fishing lines.
Turning now to another embodiment of this invention, and with reference to
With reference to
In operation, the switch 29 is turned on and the control knob 30 is used to control the amount of electrical energy from the battery 36 that is passed to the resistive mesh 33. The resistive mesh 33 heats the wall of the outside housing 5 that melts the ice with which it comes in contact with.
Turning to
The advantages to the devices of this invention are many fold. It has a quiet operation as opposed to the operation of a motor driven ice auger. There are no gasoline engine noises, no grinding or vibrating of the ice, no gasoline fumes or oil or exhaust fumes, there are no sharp blades to contend with, and no recoil during its operation.
The devices are lightweight and therefore easier to operate and transport than typical gas powered augers. There are no gasoline engine related problems such as fouled spark plugs, loose wires, and the like, and it does not require the difficult work that a spiral manual or power driven auger requires.
