ACETYLENE-GAS LAM-P.

SPECIFICATION forming part of Letters Fatent NO. 628,912, dated July 18, 1899.

Application filed July 29,1898 Serial No. 687,161- (No modeld T0 ctZZ whom it may concern:

Be it known that I, GEORGE WILL AM BAY- LEY, of New York city, borough of Brooklyn, in the county of Kings andSt-ate of New York, have invented a new and Improved Acetylene-Lamp, of which the following is a full, clear, and exact description.

My invention relates to an improvement in acetylene-lamps of that class in which an excess of carbid is used and the generation of the gas is regulated by controlling the supply of water.

My invention Comprises the novel features hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a central sectional elevation of my lamp. Fig. 2 is a sectional plan taken upon the line 2 2 of Fig. 1, and Fig. 3 is a vertical section of a removable cartridge to be used with my lamp when desired.

My device comprises an inner and an outer case, the inner of which contains the carbid and the outer the water. Between the two is placed a valve which is controlled by the pressure of the gas, so as to admit water to the carbid when the pressure falls below a fixed point and to close the valve as soon as the pressure rises above the fixed point.

The outer case A is made of any convenient or desired shape,-but preferably circular. This case is made with a removable cap or covering, by which the inner case, containing the carbid, maybe removed or inserted, as desired. The cap A is secured at its lower edge to a ring B, which is eXteriorly threaded and screws within an interiorly-threaded ring B, whichis secured to the upper edge of the body Between the two rings ber, leather, or similar material. The lower ring B, which is secured to the upper part of the base or body of the outer case A, isprovidedwitharecess adapted to receivea flange 0 upon the inner case 0. The inner case 0 is made as a cup, having an open top which is covered bya cap 0 said top having perforations C- therein, permitting the escape of the gas. The flange O fills the recess in the ring B and supports the inner case O at a proper elevation. The inner case 0 is the carbid holder or generator, and projecting upward centrally from its bottom is a cylinder E, which contains the valve mechanism by which the water is admitted to the carloidholder or cut off, as desired. The cylinder E has a cap E screwed or otherwise secured to the upper end thereof. It is also provided with a number of holes a in its side, adapted to admit water to the carbid-holder. Within this cylinder is placed a valve F, which valve, as herein shown, consists of two pistons spaced a short distance apart and provided with packing rings F in their periphery. These packing-rings may be omitted if the fit of the piston within the cylinder is carefully regulated.

The stem F of the valve is hollow and at its lower end passes through an opening in the bottom of the cylinder E. The valve is normally held down, so as to close the openings e in the cylinder by a spring F which is placed between the upper end of the valve and the cap E. The lower end of the stem F engages a flexible diaphragm I), which closes an opening in the bottom of the outer case A. This diaphragm is held byits edges between the bottom of the outer case and a ring D, which is secured thereto. This ring is threaded, as is also a cap D which is screwed thereon and forms a support for a spring D which bears against the under side of the diaphragm D. The spring D is stronger than the spring F and will, if permitted,hold the valve elevated, so that the water is freely admitted from the outer case into the carbidholder.

The water for generation of gas is placed within an annular water-reservoir G, which is placed in the upper portion of the outer case and surrounds the inner case or carbidholder. This water-reservoir is formed by an inner wall G and a bottom G which are secured to the outer wall of the casing so as to make a water-tight chamber. This chamber is filled through a cup G, which may be unscrewed from the outside. In the reservoir is placed a valve by which the water may be permitted to flow into the lower portion of the outer case and then be admitted to the valve F.

Until it is desired to use the lamp the wa ter is retained in the reservoir G, where it cannot by any possibility come in contact with the carbid. hen it is desired to light the lamp, the valve in the bottom of the water-reservoir is opened, thus permitting the Water to run into the space between the inner and outer cases.

The valve, as herein shown, consists of a cylinder g, perforated longitudinally to form a tube and inserted through the Water-reservoir. The lower end of this tube projects into the space'beneath the water-reservoir. Above the bottom of the water-reservoir a lateral holeg is formed, communicating with the interior of the water-reservoir. Within the tube 9 is inserted a valve-stem g which is threaded therein and is pointed at its lower end, so as to close the lower end of the tube. The upper end'of this stem 9 extends above the valve and is provided with a knob by which it may be readily turned.

Within the inner case or carbid-holder is placed a tube K, designed to form a connection between the spaces above and below the packing-ring B so as to secure an equalization of pressure. This tube atits upper end is connected with a hole formed through the side of the inner case above the packing-ring B and at its lower end with a hole which is preferably below the lower edge of the waterreservoir G. The lower end of the tube may, however, be connected with the outside of the inner case at any point below the packing-ring B provided such connection is at a point that is not stopped by intimate contact with the inner wall of the water-reservoir.

A vent is supplied for the water-reservoir, so that gas may be admitted thereto when the Water runs out. As herein shown, this vent consists of a tube G extending from the bottom of the water-reservoir to near its upper end. This tube is open at top and bottom, forming a free connection between the space beneath the water-reservoir and the inside of the water-reservoir. Gas flows into the water-reservoir through this tube when the water flows out.

A blow-off valve, by which excessive pressure in the lamp is obviated, is provided. This blow-off valve is located in the bottom of the outer case and consists of a valve I, which is held against the lower side of the bottom by a spring 1*, said spring being retained in position by a cap I From this valve a tube I extends upwardly to a point where it is in constant communication with the interior of the lamp. As herein shown, this tube extends within the water-reservoir and terminates just short of' the upper end of the reservoir.

The interior of the reservoir is in constant communication with the gas-chambers of the lamp through the tube G The blow-off tube I is located close alongside the vent-tube G and is in constant communication with the gas-chambers of the lamp. If by reason of any leakage of the valve F or by reason of water which remains within the carbidchamber when the valve is closed gas should be generated after the light has been turned off, this excess of gas will be discharged through the blow-off valve. This will prevent undue rise in pressure within the lamp and injury which might occur to the lamp therefrom. The burner J is connected to the cap A and has a valve-stem J extending to a point Where it may be conveniently operated.

In Fig. is shown a cartridge intended for use in connection with this lamp. As shown in Fig. 1, the carbid is placed immediately'in contact with the inner case or carbid-holder O. In some cases it may be desirable instead of this construction to use a cartridge which when removed will remove the residue left from the decomposition of the carbid. This cartridge is constructed as shown in Fig. 3. It consists of two telescopic cups H and H, having their closed ends outward. These cups are made annular, having cylinders H and H placed concentric with the outer walls and telescoping in the same manner as the cups H and H. The cylinder I'I ,Whl(3l1 forms a portion of the lower cup, has a series of perforations h in its sides, through which the Water is admitted to the carbid Within the cup. These cups are provided with a longitudinal groove h at one side, adapted to accommodate the pipe K, which is within the inner case 0. These cups are made telescopic, partly because the lime resulting from the decomposition of the carbid is of greater bulk than the carbid. The cartridge being telescopic may extend as its contents increase in volume. Two or more of these cartridges may be supplied with each lamp, one cartridge being filled and ready to insert as soon as the old cartridge is removed.

In charging the lamp with carbid and water the valve 9 will be closed, so that the water cannot gain access to the carbid unless the use of the light isdesired at once. IVhen it is desired to light the lamp, the valve 9 is opened, admitting the water to the carbid. This feature is of manifest advantage, particularly where the lamp is used upon bicycles, carriages, or in locations where it is subject to constant or occasional shocks and changes of position. It furnishes an additional security against accidental admission of water to the carbid and the high pressures and waste of gas resulting therefrom.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent I 1.
