MINER S CARBIDE LAMP.
Application filed December 22, 1919. Serial No. 346,446.
useful Improvements in Miners Carbide, Lamps, of which the following is a specification. v
This invention relates to a carbide lamp for miners and the like and the principal object of the invention is to simplify the construction and increase the effectiveness of the light. v
Another object of the invention is to lessen the liability of the stoppage of the water and gas ports and to provide means whereby these parts may be easily cleaned.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawings and specifically pointed. out in the appended claim.
In describing my invention in detail, reference will be had to the accompanying drawin s wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a longitudinal sectional view.
Figure 2 is a plan view.
Figures 3 and 4 are detail views.
As shown in these views the body of the lamp consists of the upper part 1 which forms the water chamber, the lower part 2 which forms the carbide chamber and the central part 3 which connects the two parts together and is screw threaded to receive the screw threaded neck of the carbide chamher 2. The part 1 is provided witha reduced bottom part 1 which forms the shoulder on which the bottom plate 4 rests and the central part 3 is connected to or formed with this reduced part and the screw threads in this part 3 lead tothe interior of this reduced part so that when the carbide chamber 2 is screwed home its upper end will pass into this space and thus prevent the screw threads from being choked with dust or dirt. If the female threads ended abruptly in part 8 the male threads on the carbide chamber would carry the dirt along to the closed end of the female threads and eventually this dirt would prevent the screwing home of the carbide chamber so that the lamp would leak and a new gasket would .thereinto.
have to beused' on the chamber. arrangement the dirt is carried to the space formed by the depending part 1 ofthe water chamber and the threads are kept clean. I
A tube 5 passes centrally through the water chamber and has its lowerend projecting well into the carbide chamber. This tube is provided with holes 5' so that the water may flow from the water chamber A screw threaded stud 6 has screw threaded engagement with the upper end of the tube and this stud carries a handle 7 by which it may be rotated. The open lowerend of the tube is controlled by the valve 8 which is carried by the stem 9, passing through the tube and havingits upper end reduced and passing through the stud 6 and secured thereto by the nut 10. The lower partof the stem is provided with a three-sided enlargement 11, this part acting as a guide tov the valve for giving it a proper settingwhich insures the uniform flow .of water. By moving the handle in one direction to causethe stud 6 to move upwardly in the tube the valve will be raised to its closed position so asto prevent water drop.- ping into the carbide chamber. By moving the handle in the opposite direction the stud will be lowered to open the valve.
. An opening 12 is formed in the bottom plate 4 and a burner tube 13 has its inner end connected With said opening and this tube passes through the body of the lamp and is screw threaded to receive a screw threaded cap 14 which carries the burner tip 15. A reflector 16 is held to the burner tube by said cap. A cup-shaped piece of wire gauze 17 is connected with the bottom of the plate 4 and a disc 18 of felt or similar filtering material is placed over this gauze. This gauze acts to hold the filtering material away from the opening 12 and the bottom of the plate 4 and forms a cham her to receive the gas passing through the filtering material. I prefer to form a flange 18' on the disc of filtering material, which bears against the flange at the bottom of the reduced part 1 and receives the upper screw threaded end of the carbide chamber.
The upper part of the water chamber carries a filling plug 19 and supporting hooks 20 are carried by the body.
It will thus be seen that the water flowing through the holes in the tube from the water chamber will pass down through the tube v and throughthe space between the valve and the end of thetubeand thus come in contact with the carbide. The resulting gases will rise in the carbide chamber-and will filter through the filtering material into the space formed by the gauze and the bottom of the late 4:. This gas will pass through the open mg 12 into the burner tubepwhich is packed with filtering material, and will flow through the' burner tip 'Many times when the carbide in the lamp isonl'y partly exhausted it will expand and wSome 'Oi the ash will be forcedund'er'the valve into the water tube so as to shutoff the flow of water; When'this occurs in my lamp'the-'handle isturned 'to permit the water to flow into' the tube' and then the parts come togetherf-Tt doesnt have to have acontainerto hold it in place as it'fits in the reduced part below?the' bottom'ofthe water tank. The' gauze holding the filtering material away from said bottom forms a chamber to receivethe gas and-allows alarge part of the} -fil'teri'ng material to actas" a 'filter amar By having the burner tip carried by a screw threaded cap the tip may be removed and the burner tube cleaned at any time. The packing in sald burner tube prevents the moisture being carried into" the burner by the gas; a 7
It is thought from the foregoing description that the 'advantage's'and' novel features of my invention' will be readily apparent.
I 'desire'it to be understood that I may make changes in the constru'ction and in the combination and arrangement of the several parts,'provided that such changes 'fall' w ithin the'scope of'the appended claim. o
What I claim is A lamp of the class described comprising a Water chamber and a carbide chamber; -'a water tube passing through the-Water chamher and into the carbide chamber,'a valve at the lowerend of said tube,'said valve having a triangularly shaped'part formed integral y'with the valve,a valve stem passing through the Water tube, means for bodily moving said stem and Valve vertically to open and close the valve andin'depende'nt means for rotating said stem and valve horizontally to cause saidtiiangiflar part to scrape the interior of the Water tube. In testimony whereof I afiixmy signature.
