April 5, 1932- F. SMELIK ETAL CARBIDE LAMP L Filed Oct 1, 1929 Patented Apr. 5, 1932 PFAATENT OFFICE} I FRANK SIEELIK-AND LOUISv J. KEUDWIG, OF ST. LOUIS, MISSOURI CARBIDE LAMP Application filed October 1, 1929.1 Serial No. 396,518

This invention relates to new and useful improvements in miners lamps, and particularly to the type which employs acetylene gas.

is Great annoyanceisexperienced by the miner, by reason of the clogging of the, open mg in the burner of l'llS lamp, necessitating V the extinguishing thereof and the cleaning of the said opening. Duringthis operation the gas-continues togenerate and escape, with the result that, whenthe-lamp is again Other objects and advantages will be ape-i parent from: the following description when takeniin connection wlth the accompanying drawmgs. V Y r In the drawings i p a Figure 1 isa front elevation of a miners acetylene lamp, made in accordance with'the present-invention.

Figure 2 is aside elevation of thesame.

Figure 3 is an enlarged horizontalsectional view on the line 33 of Figure 1.

Figure 4 is an enlargedgvertical sectional view: on the line H of Figure 2. I

Figure 5 isan enlarged horizontal sectional view: showing a modified rneans forattaching the reflector tothe larnpbody.

Referring particularly to the accompanying drawings, 10 represents a portion of the body of a miners acetylene lamp, from the front of the upper part of which extends the nipple 11, which is surrounded by the circular flange 12, spaced a short distance therefrom. Threaded into one side of this flange is the retaining screw 13. The reflector is indicated by the numeral lt, and has the central opening 15. Disposed at the rear of the reflector is a transverse elongated housing 16, one end of which is open, as indicated at 17, such housing havinga plurality of'radi-m' ally extending arms 18, which are terminally secured to the rear of the reflector, adj acent the periphery therof. Formed in the front and rearwalls of the housing 16, in alinelnent 65 t with each other, and in alinement with the opening 15 ofthe reflector, are the'openings 19 and 20, and formed on the rear wall oi said housing,in surrounding relation to the opening 20, is a flange 21, whichis adaptedi to receive'within the space between the nipple 11, and the flange l2, and to be held by'the said screw 13. The flange-2l is provided; with. a small recess in one side to receive the inner end of the screw 13, as shown at 22,; whereby to hold the parts together,and to. properly position the reflector on the lamp. In the front and rear walls of the housing 16, at the side of the flange 21', adjacent the open end of the housing, are the alined openings 23, which receive the pivot pin 24.

The magazine burner is indicated,-. as a; whole, by the numeral 25, and consists of the metal cup 26 ha ving, a circularseries of v openings in its bottom wall, shown at 271,. and a-plurality of regularly spaced openings; 28, .initssurrounding flange. Fitted in the cup 26 is a disk 29 which has a circular series of minute burner openings 30, registering with the before-mentioned openings 27, in. the bottom of the cup, and through which the gas flows from, the lamp body,.by means of the nipple 11. Through the centers of the; bottom of the cup, and the disk 29 isan opening 31, which receives the pivot pin 24:, when said cup is inserted inthe openend of the housing 16. In the otherend of the housing 'is a leaf spring 32 having a terminal ball member 33 which is arranged toienter the peripheral openings 28, successively, as the cup is rotated in'the housing,and,whereby the burner openings 30 registersuccess sively with the opening 15. ofthe reflector; Screwed into the opening 15' is a centrallyi apertured sleeve or bushing-34,,the innerqend- 9 of which is adapted to bear; against theouter face of the disk29, to loclrsaid disk against accidental rotation. I

When a] burner opening becomes: clogged, theminen simply unscrews thefsleeveon bush? ing 34, which releases the cup 26 so that the miner may rotate the latter with his thumb, at the exposed portion of the cups periphery, in the open end of the housing, until the ball member 33 snaps into the next peripheral opening 28, which disposes another burner opening 30 in position to discharge gas through the opening of the sleeve or bushing 34, which the miner ignites by means of the lighting device 35, mounted on the refiector.

As will be clear from the sectional View, Figure 3, the disk 29 is composed of two parts 29 and 29", the former being mica,

and disposed against the bottom of the cup 26, and the rear being formed of rubber, preferably soft rubber, which is pressed against the rear wall of the housing 16, and against the adjacent end of the nipple 11,

.when the sleeve or bushing 23% is turned up tightly, thereby holding the disk against accidental rotation, and preventing leakage of \Vhile we prefer to secure the reflector to the lamp body by means of the screw 13, we

wish it understood that we may internally thread the flange 12, to receive therein the externally threaded flange or nipple 21, of the reflector, as clearly shown in Figure 5. Also, we may internally thread the flange 21 to screw onto the nipple 11.

What is claimed is:

1. A miners lamp including a support having a central opening, a rotatable apertured disk mounted at the rear of the support in position to successively dispose its openings in register with the said central opening, the disk having peripheral openings, a detent for engagement with the peripheral openings, and means within the support opening for locking the disk against accidental rotation.

2. A magazine burner for a miners gas lamp including a support having a central opening, a casing on the rear of the support, a rotatable disk in the casing having burner openings for successive register with the opening of the support, the periphery of the disk having a recess adjacent each burner opening, a detent in the casing for successive engagement in the recesses to hold the disk in its different adjusted positions, and a sleeve threaded into the central opening of the suport for engagement with a face of the disk to hold the opposite face thereof frictionally against a wall of said casing.

3. A magazine burner for a miners gas lamp including a support having alining gas openings, a rotatable disk in the support having a plurality of burners arranged to be successively registered with said alined openings, and means 011 the support for pressing said disk into gas-tight relation to one of said alined openings.

4. A magazine burner for a miners gas lamp including a gas delivering means, a

support mounted on the gas delivering means and having gas openings in receiving relation thereto, agas burner mounted in the support and movable into and out of register with said gas openings, and means within one of said gas openings for forcing the burner into gas-tight relation to said delivering means.

5. A magazine burner for a miners gas lamp including a gas delivering nipple, a support mounted on said nipple and having gas openings registering therewith, a gas burner mounted in the support in gas transferring relation to said gas openings, and means within one of said gas openings for forcing said burner into gas-tight relation to said nipple.

6. A magazine burner for a miners gas lamp including a gas delivering nipple, a support mounted on the nipple and having alining gas openings registering with said nipple, a burner magazine rotatable in said support to successively register its burners with said openings, a packing on the magazinc, and means in one of said gas openings manipulatable against said magazine whereby to force said packing into gastight engagement with said nipple.

7. A magazine burner for a miners gas lamp including a support having alined openings, means for attaching said support to the body of a lamp, a disk rotatable in said support, and having burners arranged for successive register with said alined openings, means on the support engaged with said disk for releasably holding the latter with a burner in registered relation to said openings, and a sleeve threaded into one of said alined openings in surrounding relation to the flame issuing from said registered burner for pressing said disk into gas-tight engagement with said lamp in surrounding relation to said burner.

8. The combination with the body of a miners gas lamp having a gas delivering nipple, of a support including a casing mounted on the said nipple and having a central opening, a rotatable member in the casing having a plurality of burners arranged to be successively registered with said opening, a packing element on the rotatable memher, and a sleeve threaded into said central opening for engagement with said rotatable member to press said packing element into gas-tight engagement with said nipple.

In testimony whereof we afiix our signatures.
