  • This invention relates to radiant-type electrical heating with an infrared heating element having a reflector therefor.
  • the cooling'gas may be either air or an inert gas such as nitrogen.
  • the lamp It is important that the lamp not be energized unless there is a flow of cooling gas. If the lamp operates without the flow of cooling gas, the heat from the lamp will destroy the reflector.
  • These devices are often used by telephone installation men in underground tuunels or manholes where there is sometimes an explosive atmosphere of methane, acetylene, propane or the like. Where this situation exists, it is essential that the temsphere.
  • An object of this invention is to provide a lamp to concentrate heat upon a small area of an object.
  • Another object is to make such a lamp usable in an explosive atmosphere.
  • Still further objects are to achieve the above with a method that is versatile, rapid, efficient, and inexpensive, and does not require skilled people to adjust, operate, and maintain.
  • FIG. 1 is a longitudinal sectional view of an apparatus according to this invention with some parts shown schematically for clarity and with arrows showing the flow of cooling gas through the apparatus.
  • FIG. 2 is a schematic representation of the electrical circuits as used therein.
  • FIG. 3 is a sectional view particularly showing some of the air passage with the shroud removed, taken sub stantially on line 33 of FIG. 1.
  • the apparatus has handle or base 10.
  • the handle 10 is conveniently in the form of a pistol grip so the workman can readily hold itin his hand and direct the heat rays from the device upon the work area.
  • the overall appearance of the device is more readily seen from the drawings in my design patent application referred to above.
  • Gas connection 12 is at the bottom of the handle 10. Not shown in FIG. 1 is electrical connections 41 at the bottom of the handle 10.
  • FIG. 2 shows the electrical connection 14 in the form of a conventional electrical power cable which connects the device to a power source of electricity 16.
  • the gas connection 12 is connected by conventional gas hose to a source of cooling gas under pressure 18.
  • the gas source 18 might well be compressed air from a conventional storage tank or from a gas compressor it might be from a bottle of inert gas such as nitrogen.
  • Heating insulating discs 20 and plenum chamber 22 are attached to the handle on the opposite end of the pistol grip from the gas connector 12.
  • Lamp holder disc 24 is attached to the plenum chamber 22.
  • the disc 24 has a plurality of small gas discharge holes 26 therein which are arranged along the perimeter thereof.
  • Lamp holder socket 28 is centrally attached to the disc 24.
  • the lafnp holder socket 28 is not shown in detail inasmuch as it is of conventional commercial design as is iodine quartz lamp 30 therein.
  • the lamp 30 produces infrared radiation asbrilliant, visible light.
  • Shroud 32' is circular in cross section and is telescoped over and securely attached to the outside of the plenum chamber 22. It is made by conventional tachniques of thin walled aluminum material. As readily seen in FIG 1, filter end 34 of the shroud 32 is much larger in diameter than the end which connects onto the plenum chamber 22.
  • Attachment ring 36 is telescoped within the shroud 32 at the filter end 34.
  • the filter 40 rests upon internal shoulder 38 of the ring 36.
  • the filter 40 is held in place by spring clips 44 which themselves are held in place by screws 46.
  • the screws 46 form an anchor by which one end of tension springs 48 are attached.
  • the tension springs 48 extend from the screws 46 to a hook at opening 50 of reflector 52.
  • the reflector 52 is a conventional parabolic shaped reflector made of polished aluminum. Because of the cooling which I describe, it is not necessary to use a heat resistant metal nor is itnecessary to take elaborate precautions to prevent the reflecting surface of the reflector from becoming dulled. As may be seen from the above description and the drawings, the reflector is held in place by the springs 48 holding them firmly against the spring clips 44.
  • Air passage 54 is between the reflector '52 and the shroud 32. If air is supplied to the interior of the plenum chamber 22, it will pass through the holes 26 in the mounting disc 24 to within the shroud 32 and along the outside of the reflector 52 and through the openings 42 to blow along the outside surface of the filter 40. There is another flow of gas which would be through the opening 50, around the lamp 30, and between the reflector 52 and the filter 40, and then through the air passageways 42.
  • the base 10 has conduit 56 for gas passage leading from the gas connection 12 to valve chamber 58.
  • the valve chamber 58 is axially aligned with conduit 60 which extends from the valve chamber 58 to the plenum chamber 22, through discs 20.
  • Valve 62 is mounted within the valve chamber 58 and is operated by hand knob 64 on the exterior of the handle 10. When the valve knob 64 is pulled outward,
  • connection 12 Spacer is within the conduit so when the valve 62 is open and the gas pushesthe magnet 66 upward, the magnet is properly positioned.
  • the spacer 70 has a hole therein so it does not impede the flow of gas around and therethrough.
  • Gas flow repositions the magnet 66 relative to magnetic switch 72 so that it closes the magnetic switch.
  • the arrangement of magnetic switches with magnets is well known to the art, however, the movement of the magnets by gas flow and also using it in this particular arrangement is considered to beinvention by me.
  • the schematic representation of the electrical circuits shows the power source of electricity 16 connected to the lamp 30.
  • One wire is directly connected, the other wire is connected to the source through triact 74 when the triac is closed.
  • the triac will be recognized as a switching means or means for connecting power from the power source to the lamp 30.
  • the switch 72 is electrically connected between the power source 16 and the control connection of the triac 74 through resister 76. The switch 72 activates the triac so the triac closes to energize the lamp 30. All this will be understood by those skilled in the art.
  • FIG. 1 does not show the physical placement of the triac 74 within the handle 10 because applicant believes that any mechanic ordinarily skilled in tools of this sort would readily be able to place the triac within a cavity within the handle 10'and connect the wires from the magnetic switch 72 to the triac and to the lamp 30.
  • triacs are well known and able on the market.
  • the gas also cools the filter 40.
  • the filter 40 will become the hottest part of the device. Therefore, it is important that it be cooled also.
  • the filter temperature does increase so it is above the ignition point of the atmosphere, it will still be safe because the filter will be bathed or have a gas shield around it. This will be well understood if nitrogen is used as the cooling gas. Even if compressed air is used as a cooling gas, by having the filter and the parts shielded by the compressed air, this prevents methane or other explosive mixture to be within this area.
  • the wiring through the handle 10 will permit some cooling gases to escape in this area.
  • the triac 74 and the magnetic switch 72 are hermetically sealed, they are also bathed or shielded by the same cooling gas which flows over the lamp 30 and reflector 52.
  • the cooling gas itself will reach a rather high temperature.
  • the air ports or openings or passageways 42 are cut along the surface of the ring 36 so that the air flows evenly from the edges of the filter 40 to the center of the filter; from there the air flows out along the axis of the device which is also the main heat beam coming from the lamp 30.
  • the preheated gas which has been cooling the device blows upon the work. This will help in heating the work.
  • the air valve 62 slow acting. This may be done two ways. One is to put threads upon the shank attached to the hand knob 64. If the valve 62 commercially availis slow acting, there will be a small gas flow, shielding the parts before there is sufficient gas flow to move the magnet 66. When the device is turned off, the gas flow is reduced sufficiently so the electricity is turned off and thereafter there is a continuing gas flow before the valve is completely closed. Another way of achieving the slow movement of the valve 62 is to make the parts extremely tight or small clearance so it is hard to move and the hand knob moves only slowly in opening and closing.
  • said filter openings forming means operatively associated with the shroud for directing the gas over the outside of the filter to also cool the filter
  • detecting means attached to the base and associated with one of said gas conduits for detecting a flow of gas from the gas source to the passage
  • said magnet is mounted for movement responsive to gas flow in the conduit said switch is magnetically responsive.
