Application filed Mai-ch29, 192-2. Seria1 N o.-54 7,78o."

TO: all whom it m concern Q1 zen of the United States; residing atlVIarseilles, in the county '01": LaSallea-nd State of; Illinois: have invented certain new and useful Improvementsin :Miners" Lamps, 0t

which the followingrs a specificationygreference being hadto the accompanying draw? lngs. v

This invention relatesto minerslamps,

In miners lamps as ordinarily constriurt ed, there is but one-burnerand as a conacetylene gas.

sequence if this burner heeomes clogged or blocked so that a et ofgas cannot issue therefrom, the miner is obliged to stop work and clean out theopening of the burner, thus losing time. lene lamps it isusual to connect the-body ofthe lainp'to the water reservoir and generatorby means of! screw-threads The carbide causes, a sort of cement to.forinbe tween these screw-threadsgand as a conse-v quence the lower portion of the lamp-f can; i not be unscrewed from the"upperportion and the lamp must {be thrown gawaywor the lower portion of the lamp broken off in attempting tounscrew and detach the water reservoir and generator. the ordinary miners" lamps of tl1isrharacter there is a ca clasp which is -mounted: upon the-lamp itself and which forms an.

encumbrance.

One of the objects-pt the present inven.

tion is to provide a lamp oiithischaracter Y with two burners and a valve shit table to close one of the; burners and ,permit the passage ofithe gas through the other burner,

or close off the last named burner and per-v mit the passage of the gas throughthe first issuing from theburner which is open thus named burner so that ifo-ne of the burners become clogged it is only necessary for the valve to be shifted and thediminishinp; flame from the clogged burnerwi ll light the jet permitting the miner toxclean out the clogged burnerat-his,leisure.

further object is to provide ver y' sim. ple means wherehythis opening and; closing ofthe two' burnersmaybe accomplished. a

still further object is to provide fora detachable connection between the baseor generating portion of the lamp. fandthe bodyof; the lamp' whichydoes not require .erator and the body will be held in to miners l mp "using i a e a I lasp-auditin permi i i b9 handled Furthermore, in miners acety- Furtheurm'ore in I body and generator to bereadily detached i 1 Be itknown that I, P u'rnn Mrsmo a citifrom 2 each other when necessary, this con nectionbeingsuch, however, that thewgen gas tight engagementflw tn each other.

Still another obg ect is to provide a clasp adapted'to bepermanentlyattached tothe oapiofetheniiner and Whichlis adaptedito 'engage the baseofthehook usually found on lamps of this Echaracter, thusrendering the-lamp free of theencumbrance of the i more readily, p i

Other objects-"willxappear in the course offlthefollowing;"description. '7 1 invention is llustrated in the uccompanying drawings, wherein:- 1

The; body 1.1 has the usur'. form and is I a vertical, sectional view drawings; 10 desig,

closed at its upper end bjy a plate 12 having it iDi-sposed between the contronting ends ofithe tubes15and 16is atsleeve 18 which encloses a solidrubber block 19 constituting a valve. Whenthissleeve 18 is shifted in one direction, the-rubberqbloclr will bear against one of the a ends 17 and close this particular gastube', while when it is shifted the other direction it will close theother gas tube The amount of this movement nece'ssaryinorder to obscene or the other eee eea i veras htv he e v 8 h a laterally projecting portion 20 which isinteriorly screw-threaded, and engaging this interior screw-thread is a wire or rod 21 which extendsout through a tube 22 which is attached to the wall of the body i1 and projects in both directions from this,

wall. Within this tube is disposed a rubber sleeve 23 which fits around the wire or rod 21 tightly so as toprevent the escape of gas, this sleeve forming a packing.

Fitting over the outer projecting end of the tube 22 is a cap 24 which is longitudinally movable upon the tube 22 and which has an interior rubber lining or sleeve 25 ting the tube closely. The rod or wire 21 1s attached at its end to this'cap 24 so that when the cap moves longitudinally the wire or rod will move longitudinally'and vice versa. The extremity of the 'cap'has an in-f ternally screw-threaded socket with which a screw 26 is adapted to engage, and attached to this cap 24 by the screw 26 is an outward ly projecting arm 27, the extremity of which is perforated. Projecting from the sidewall of the body 11 and attached firmly thereto is an interiorly screw-threaded, tubular'member 28, and having screw-threaded engagement with this member is the rod 29. The

arm 27 to the cap 25 and thus to the rod 21,

which by reason of its connection to the sleeve 24; causes the valve constituted b this sleeve and the plug 19 to shift longitudinally into engagement with one or the other of the branches 17 of the gasfpipes 15 or 16. Normally, of course, this valve is held against one of the branches 17 so as toper- 'mit the free entrance of gas into the other branch and its exhaustthrough the appropriate gas pipe or tip. If this tip of the gas pipe becomes clogged so thatthe light is reduced or is failing, then the handle on the rod.29 is turned and this causesthe movement of the valve 20 in the manner heretofore describedso as to close this clogged pipe to the entrance of gas and permit the entrance of gas into the unclogged pipe. It will, of course, be understood that the branches, 17 of the pipe'16 open beneath the septum,3l which forms the bottom of the water chamber 32 Extending downward from the water chamber is the usual water supply pipe 33 which discharges intolthe carbide receptacle l0 and they discharge of water is controlled by the usualvalve, the

valve rod of which is designated34. Inasmuch astlns valve and valve rod are'comseat 37 for agasket '38, against which the flared lower end of the bod 11 bears. For the purpose of securely holc ing thebody 11 to the carbide receptacle and generator 10, 1 form the upper end of the portion 10 with an interrupted flange '39, this flange beinginterrupted at a'plurality of points, as at 40. The flange adjacent each interruption is bevelled, as n41. The body has attached to it a plurality of downwardly extending hooks 42 which extend downward and out ward'and'then sharply inward, and when the body and generator are put together these hooks pass down through the interruptions 40 and then the body of the lamp is given a turn in one direction and the hooks move along the bevelled face 41 anddraw the body 11 into close and gas-tight engagement with the carbide receptacle or generator 10. This construction avoids the necessity of using screw-threads and provides a construction whereby the two sections of the lamp may be readily separated from each other and readily and quickly joined and avoids the objections before referred to in I cident to screw-threading the two sections together. v The body portion 11 is provided with the usual hook 43 whereby the lamp may be connected to the miners cap. This hookis made somewhat longer than. the usual hook and extends downward and across the circumferentialrecess 44 in the body 11. A clip 45 formed of astrip of resilient metal is intended to'be attached to the miners cap,this strip at its middle being folded or'corrugated, as at 46, to provide a resilient socket 4T betweenth'e corrugations which is adapted to embrace that portion of the hook 43 which extends across'the recess l li The advantages of'my invention reside in the fact thatby having two burners, when one burner is blocked the miner can turn it off and turn the other on and so have a light immediatelyythus losing no time in looking for a light while attempting to drill out the blocked burnerQ The other burner can be drilled at h'isleisure, WVhen a'burner is blocked, it is seldo'm completely blocked so that a little light still shows and thus when the other burner is turned on it lights without the useo'f a match. The valve, it will be seen,is madein three pieces so that any one of'thern' can be removed and replaced in case of necessity. The advantage of the clasp 4:5 is that the clasp is always on the'miners cap and does not make the lamp ungainly and hard tohandl'efas it would do-if theclasp were on the lamp. At the same time it embraces the hookstrongly and holds the lamp" firmly in place against accidental o detachment or swinging. By disposing the valve between the two branches 17, it is obvious that the valve in shifting from a position closing one gas pipe to a position closing the other gas pipe will traverse a point where both pipes are open so that the gas is passing to the clogged *pipe and to the free pipe at the same time so that the gas issuing from the free pipe can become ignited from "the small. amount of clogged pipe.

' IVhile I have illustrated certain details ofconstruction which I have found to be particularly effective, it is obvious that these details might be changed in many "ways without departing fromthe spirit of the invention, and it will be-obvious that various attachments ordinarily found in miners lamps may be used with a lamp constructed in accordance with the present invention,

described, a body constituting a water I containing chamber, a pair of burner pipes chamber and a'carbide chamber connected to the body but separated from the water extending through the side wall of the body and opening into the carbide chamber, said pipes having confronting inner ends, a valve disposed between the confronting ends of the burner pipes and shiftable into contact with one or the other of the burner pipes, and means exterior to the body whereby the valve may be shifted.
