To all Lo/wm t may concer/n:

Be it known that l, Ancrrini A'rnrns, a citizen of the United States, residing at Glen Ferris, inthe county of Fayette and State of TWest Virginia, have invented new and useful Improvements in Miners Carbide Lamps, of which the 'Eollowingfis a specilication. f d

In carrying out the present 'invention it is my purpose to improve and simplify the general construction 'ot carbide miners lamps and to provide a lamp which will embody in its construction, among otherfe'a'- tures, a water receptacle, a carbide receptacle and a gas chamber interposedfbetween the water receptacle and the carbide receptacle and connected to the carbide receptacle in.

such manner that the carbide receptacle may be readily Adetached therefrom when itv is necessary toreplenish the same, without cutting ofi the flow oit gas from the'k gas chamber to the burner, the gas chamberbeing equipped with a valve by whichcommunication between such chamber and the atmosphere may be cut ott when the carbidelre ceptacle Vis detached' and being also equipped with a hand pump, whereby the gas therein may be placed yunder slightly increased pres sure whenever necessary or desired.

With the above recited objects in View, and others of a similar' nature, the invention resides in the construction, combination and arrangement of parts set forth in 'and falling within the scope of the appended claim.

In the accompanying drawings: l

Figure 1 is a view in side elevation of a carbide miners lamp constructed in accordance with my invention.

lFigure 2 is a vertical sectional view through the same.

Figure 3 is a cross sectional View on the line 3m?) of Figure 2.

Referring now to the drawings in detail, 1 designates a water container which, in the present instance, is circular' in horizontal. cross section and has its top wallformed with a water inlet opening that is covered by a cap 2. The side wall of the receptacle 1 is equipped with an outwardly flared hub 3 that carries the lamp burner and ata point diametrically opposite the hood 3 the side wall of the receptacle 1 is provided with a hook 4 by which the lamp may be carried or attached to the miners cap. y

Below the water receptacle 1 is a lgas chamber 5 which, in the present instance, is

circular in f'cross section, as 4shown more clearlyfin Figure?) of the^draw1ngslf The i upper end ofthe receptacleis 'reducedl'in diameter and tted into ythe bottom of the receptacle flinorder to' close thelowerend ot the `water receptacle. The bottom' wall 5 of the gas chamber 511s formed with a depending ycircular flange 6. 7 designates a lcarbide retainer havingits upper end formed with'an'ext-eri'orly threaded circular'tlange 8 that engages in the lflange 6, ,so that the upper wend 'of 'the carbide container 7 may be closed' by the bottom wall of the gas chamber Connected to" the top' wall ofthe tacleand extending through the water receptacleand 'the gas chamber `and into the carbidereceptacle 7 is awater tube9. Adjacent to the bottom of the water receptacle 1 the tube 9 is'lr'ormed with an outward openwater receptacle `1| cent'rally ofk 'such recep! ing 10,`and slidably mounted within the tube ,f, 9 andnormally closing the 'outletjopening 10 is a valve v.plug 11, connected with the lower end of k,a stem 12 that extends" upwardly throughthe top of ythe water 'receptacle and is"V equipped yat its upper end with 'arbutton 18. Extending across the water tube 9 below the opening` 10 therein is a pin 14, and interposed between thepin 14 land the' valve plug 11 isa spring 15. The plug l1 is'for'med with vertical bores 16 through which the water maylow when the plug is depressed by the button 13 v,against the action of the ,i spring .15 to kuncover the outlet opening 10,

and when the outlety opening is uncovered the water flows from the water receptacle l through the tube y9 into the carbide recep taclelf?, thereby enablingr gas to be generated. in the carbide receptacle. The bottom wall vof the' gas chamber 5 is formed with a port 17 and on its upper surfacelat opposite/sides of the port l'this bottom wall isformed f with guides 18 spaced apart in parallelism. Slidably mounted in the guides 18 is a-valve plate 19`formed with a port 2O and provided with a stem 21 that extends outwardly' through they `side ywall of the gas chamber andv terminates in a knob 22. f Normallythe Vrport 20A is inalinement with the port 17,` so

that the gas generated by the water and carvbide may flow into the gas chamber 5. From the gas `chamber 5 the gas passes througgghy the tube 28 `to ther burner in the hood 3. l

When the 'supply of carbide in the receptacle 7 has become exhausted and it is desired to replenish the same, the valve plate 19 is lmoved' within the guides 18 to close the port 17, thereby enabling the carbide receptacle to be detached for refilling without permitting the gas in the gas chamber to escape to the atmosphere. u

Connected to the side wall orthe gas chamber 5 is a pump which comprises a tube 24 having the portion beyond the gas chamber formed with an `air vent port 25 and its inner endequifpped with an inwardly opening check valve V26. TWithiny the tube 24- is avplung'er 27 equipped with a stem 28, the outer end or which terminates in a handle 29; By means or thisv construction it will be seen that the plunger 2'4" may be manipulated to draw gas into the tube' ik and to force such gas` past the check valve 26 into the gas chamber 5, in order to place the gas therein under pressure for maintaining a continuous burning or the flame at the burner in the' hood While the carbide is being replenished in tank 7 l, I have entered into a detailed description of theV construction ,and relative arrangementor parts embraced in the present and preferred embodiment or my invention. with I a view to imparting a full, clearand exact understanding` or the said embodiment. l d0 not desire, however, to be understood as confining myself to the said speciiic construction andV re'ative arrangement lor parts, inasmuch asin the future practice or my invention Ysuch ychanges or modifications may be made as fairly rail within the scope cla-1m.

Having thus described the invention, what is claimed as new, is

A carbide lamp comprising a body having a gas chamber, .a water chamber and a carbide chamber, said chambers being superimposed with relation `to each other, a tube extending from the top wall or the gas chamber and passing transversely through the gas chamber and the water chamber and having its lower end por-v tion received in the carbide chamber with its lower end open and spaced from the bottom or the said chamber, said tube beor my invention as defined by myappended ing provided at its side and at `a point 1^ above the bottom oi the gas chamber with an opening, a piston slidably mounted in the tube and provided with openings passing therethrough, a spring housed within the tube and .confined at one end upon a support and bearing at its opposite endv against the piston and serving to normally holdthe piston in a cosed position over the openingv in the sidey or the tube, and rod connected with the piston and passing through the top or the gas chamber, said rod adapted t0 serve as means for depressing the piston against, the tension or the springv and tor vremoving the piston from over the opening in the side or the tube.

In testimony wh'ereoic 1 affix my signa-` ture. u ,p y Anemia ATKINS.`
