I YACET'YLENE-GAS LAMP.

SPECIFICATION forming part of Letters Patent NO. 634,757, dated October 10, 1899.

. Application filed April 14, 1899. Serial No. 713,009. No model.)

To all whont it may concern:

Be it known that I, PETER JossERAND, of Josserand, in the county of Trinity and State of Texas, have invented a new and improved Acetylene-Gas Lamp, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved acetylene-gas lamp which is simple and durable in construction, more especially designed for use as a portable tablelamp,and arranged to insure a uniform, perfeet, and brilliant light.

The invention consists of novel features and parts and combinations of the same, as will be fullydescribed hereinafter and then pointed out in the claims.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement. Fig. 2 is a sectional side elevation of the same, and Fig. 3 is an enlarged sectional side elevation-of the self-regulating valve.

The improved acetylene-gas lamp is provided with a suitable base A, on which is set a bowl, forming a generator B and containing the calcium carbid C. On the neck B of the generator Bis screwed a cap D, terminating in anupwardly-extending pipe E, supporting a water-reservoir F, adapted to be filled with water through a filling-cap G, having a suit able vent-pipe H to admit air to the water that the latter may flow to the generator B, as hereinafter more fully described.

The upper end of the pipe E connects with a pipe I, extending centrally through the water-reservoir F to connect at the upper end with the burners J'for burning the generated gas to produce the desired light.-

From the bottom of the water-reservoir F at one side of the pipe E extends downward a pipe K, bent upwardly at its lower. end to connect withthe chamber N of a self-regulating valve N. (Shown in detail in Fig. 3.) The chamber N is provided with avalve N adapted to be seated on the end of the pipe K,said valve having adownwardly-extending stem N fitting loosely in the opening of the pipe K to insure a proper seating of said valve N A pipe 0 leads from the chamber N a short distance above the valve N and extends through the cap'D into the generator, preferably at the middle thereof, the lower end 0 of the pipe 0 being contracted to allow but a drop of water to pass out of the pipe at'a time. The top of the valve N is provided with a stem N countersunk at its top to receive the pointed lower end P of a screw-rod P, screwed in a screw-cap N closing the upper end of the collar P Now when the sore w-rod P is screwed downward the valve N is moved to its seat to disconnect the pipe K from the chamber N; but when it is desired to use the lamp the screwrod is screwed outward until the collar P abuts against the under sideof the cap N to allow the spring Q to just hold the valve N loosely to its seat.

In order to fill the generatonbowl with calcium carbid, it is only necessary to unscrew the cap D, and after the desired quantity of calcium carbid is placed in the b0 wl then the cap is again screwed upon the npck B. The reservoir F is filled with water through the filling-cap G, and when it is desired to use the lamp the screw-rod P is screwed outward, as above explained, so that the water from the overhead reservoir F can flow through the .pipe K against the valve N and lift-the latter 0d its seat and to allow the water to rise in the chamber N and finally flow into the pipe 0 and down the same into the generator B, the water passing in drops from the contra-cted end 0 upon the carbid O to cause a generation of gas, This gas rises in the generator and passes through the cap 1) and pipe E into the pipe I and to the burners J -to pro duce a steady uniform flame and a very brilliant light.

In case the pressure of gas generated in the generator B overbalances the water-pressure on the valve N then the latter is forced to its seat by the overbalancing pressure to pre vent water from passing from the reservoir water passing through the regulating-valve and the pipe 0 to the generator is effectively regulated to insure a uniform generation of gas, and consequently a uniform flame at the burner J. By reducing theend of the pipe 0 Within the generator B Water is admitted but drop by drop to prevent a' too quick generation of gas and a consequent flashing up of theflame at the burner J.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 4 1. An acetylene-gas lamp, comprising a base, a bowl carried by the base and adapted to contain calcium carbi'd, said bowl being formed with a screw-threaded neck, a cap screwing on the neck of the bowl and formed with a contracted tubular extension, a reservoir on the upper end of the tubular'extension and integral therewith, said reservoir having a central passage extending through it, said passage being of less diameter than the tubular extension and opening into the same'a pipe in the said passage and having an open inner end, the outer end of said pipe projecting above the reservoir and provided with a burner, a water-pipe leading from the bottom of the reservoir, at one side of the tubular extension intov the bowl, and a self-regulating valve in the said pipe outside of the lamp substantially as described.

2. Inan acetylene-gas lamp, the combination with a generator, and a Water-reservoir above the same, of a'valve-chamber, a pipe leading from the watenreservoir to the valvechamber, a spring-supported valve in'the said chamber and regulating the admission of Water to the Ch%t1I1l)61,'ft screw-rod for forcing the valve to its seat, and a pipe leading from the valve-chamber above the entrance of the pipe leading from the reservoir and extending'into the generator, substantially as described.

In an acetylenergas lamp, the combination with a generator, and a Water-reservoir above the generator, of a valve-chamber, a pipe leading from the Water-reservoir to the bottom of the valve-chamber-for closing the end of said pipe, a valve in said chamber, a screw-rod engaging the valve-stein, a stop collar on the screw-rod, a coiled spring sur-' rounding the screw-rod and valve-stein, the.

spring being secured to the screw-rod and supporting the valve, and a pipe leading from the valve-chamber above the valve to the generator, substantially as described.
