ACETYLENE- GAS LAMP.

Specification of Letters Patent.

Patented Get. 31, 19.11.

Application tiled December 3 1, 1910. Serial No. 600,345.

My invention relates to certain new' andv useful improvements in acetylene lamps, and the object ofamy invention is to so improve the construction as to cause the same to burn longer and steadier than has heretofore been possible on a given charge of calcium cai'- bid, and also to greatly decrease vthe liability of the lamp becoming clogged.

With these and other objects in view my invention consists in certain constructions, combinations andarrangements of parts, ythe preferred form of which will be first described in connection with the accompany` ing drawings, and. then the invention parin the appended claims. 4

Referring to the drawings wherein the same part is designated by the same reference numeral wherever it occurs., Figure 1 is a central longitudinal section of an lacetylene lamp in which my improvements areenibodied; Fig. 2 is a perspective view of my improvement detached t'roni` the lamp, and Fig. 3 is a central cross section of Fig. 2. A n

,5 ,designatesLa receptacle for containing calcium carbid which, in the toi-in of my invention shown, is provided with a screwthreaded neck t3 surrounded by a rubber gasketI 7 adapted to screw into a cap 8, on which is mounted the water reservoir 9, having" a filler opening 10 and a water controlling valve 11, zuhipted to control the flow of water from tyie water reservoir to4 the carbid receptacle.

l2 is a pipe extending from the water reservoir into the carbid receptacle and `through which the water passes to the bottom of the receptaclel and 12 is a rod loosely extending through the valve 11 and pipe 12 by means of which the carbid may be agitated.

13 is the burner which extends 'out from the top of the cap 8, and the inner end of the burner pipe is covered by a block ot' by a cross wire' 15.

or similar substance 14 held in place All these parts so far described are of a general torni ot burner, and consequently torni no part of my invention.

In the use of a lamp ofthe above-referred to type it has been found that'after a few days use the felt 14; covering the end of the burner tube would become wet and clogged,

thus preventing the flow' ot gas and render' ing the lamp inoperative. Furthermore the .particles of carbid will coat the felt and work in around the inner end ofthe burner tube,' which increases the tendency of the tube to ,clog up; By my invention I obviate this dilticulty and cause a lamp of the character thus described to burn continuously without clogging.

16 designates a metal plate provided with a centralperforation 17, through which lthe water pipel l2 extends. .The plate is also provided with the perforation's 18.

19 designates a section of cork secured to the under side of tlieplate 16,' said cork bey ing provided with the central perforation 20 in line with the perforation 17 of the plate, and the perforations 21 in line with the pert'orations 18. Preferably and as` shown the pci'oi'ations'21 are conical and provided with a bushing 21 wliichvinay be either integral with the plate 16, as shown in Fig. 1., or 'separate therefrom, as shown in Fig. 3, and in the perforations 21 I place ainass of cotton, or the like 22, so that gas passing up to the burner must pass througl: the mass ot cotton. The cork fits snugly int-o the mouth ot' the carbid .receptacle and closes the same, lt prevents dampness passing up to the '.t'elt and consequently the felt cannot become clogged. Should the small i'nasses of cotton in the openings 21 become clogged they'can be easily 'and quickly removed and'replaced. It is found'in practice, howevei', thatthese small masses of cotton do not clog up the way the block of felt infront of the gas tube does when a lamp is not provided with my invent-ion.

I realize that .considerable variation/is possible in the details of construction and arrangement of parts Without departing from the .spirit of my invention, ,and I therefore do vnot intend to limit myself to the specific form' shown and described.

. Having thus described my invention lamp which comprises a csmhd rsssrvo, a, csp for the reservoir, a Wssl' rscspmcle molmed on the csp, s bunrney @Xmuding fom the csp and a. Mock 0i fibrous mamaria?. covering` the innsr and of the bunfal, of a metallic pate, a secon of Cosk secured to the undef side @if the plait@ and sdaptsd to dos@ the, opening of Jah@ cslbd esswo" with the pas esing upon th@ edge of the opening of th@ l'esefmra s. pmalty OTE conical openings 'through the cmk and plate for @he passage of gas from the resem to the bums? and brous ma.'- kma oosely packed in said openings.

2. The combination with an sceyens :lamp which comprises a carbid mservor, a, Cap 'olr th@ reservoir, a waiter recsptacs mouned 011 the Cap7 a burner extending;
