/yf Z/ UNITED STATES PATENT OFFICE.

LEANDER H. LITTLE, OF FORT IVORTH, TEXAS, ASSIGNOR TO AMERICAN ACETYLENE GAS LIGHT COMPANY, A CORPORATION OF TEXAS.

ACETYLENE-GAS GENERATOR.

Speccaton of Letters Patent.

Patented Sept. 25, 1906.

Application led February 13, 1906. Serial No. 300,870.

To all whom it may concern:

Be it known that I, LEANDER H. LITTLE, a citizen of the United States, residing at Fort l/Vorth, Texas, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a speciiication.

This invention relates to gas-generators, and more particularly to machines for feeding carbid into water and for collecting the gas generated therefrom into suitable vessels for distribution; and the object is to provide a machine which will automatically feed carbid and which is provided with suitable vessels in which the gas is generated and suitable vessels in which the gas is collected and to equip the machine with safety devices for preventing explosions.

One of the advantages of machines constructed in accordance with this invention is that a gas-bell is provided which is capable of rising and falling two or three feet or more, and yet feeding devices are provided which will be operated so perfectly and automatically by the movement of the gas-bell that the rise and fall of the gas-bell will be very little, if any, more than one inch. The advantage of this is that the lights furnished by the gas will be steady and of uniform strength.

Other objects and advantages will be fully explained in the following description, and the invention will be more particularly pointed out in the claims.

Reference isl had to the accompanying.

drawings, which form a part of this application and specification.

Figure 1 is a side elevation of the complete machine. Fig. 2 is a plan view'of the improved feeder. Fig. 8 is a vertical section of the same. Fig.v 4 is a horizontal section of the gas-bell along the line ai a: of Fig. 1.

Similar characters of reference are used to indicate the same parts throughout the several views.

This invention is provided with a generating-tank 1, called herein the generaton A carbid-receptacle 2 is mounted above the generator 1 and connected thereto by a coupling composed of a male part 3 and a female part 4, each part having horizontal flanges 5, with suitable packing 6 placed between the iianges. The carbid-holder 2 is provided with a glass 7, through which the carbid can be seen. Carbid may be placed in the receptacle through a screw-capped orifice 7. Water may be poured in the tank 1 through a hopper 8, which is mounted on a pipe 9, which projects down in the tank or generator 1 near the bottom thereof. The pipe 9 is provided with a cut-off cock 10. Water may also be placed in the generator 1 through a pipe 11, which is provided with a cap 12. The pipe 11 may be connected with a pipe from the water-supply source. The generator 1 is provided with a gage-cock 13, located at the water-line of the generator. Water is run into the generator, and the cock 13 is left open. As soon as water commences to run out of the cock 13 the cock is closed. Means are provided for cleaning spent carbid out of the generator. A An ordinary faucet 14 is connected in the generator at the bottom thereof. A rod 15 for stirring the spent carbid is on the bottom of the generator. This rod projects through the upper part of the generator down t'o the bottom of the generator and is bent at right angle, so that it will sweep about the bottom of the generator. A seal is provided, which consists of a pipe 16, having a funnel-shaped top 17, and which enters the upper part of the generator and projects far below the water-line.

Means are provided for feeding the carbid to the generator. A horizontal cut-off 18 operates in the coupling 3. The slide or cutofl 18 is carried by a rod 19, and the cut-ofi' operates in grooves 2() at the sides thereof in the coupling 3. The slide and the rod 19 may be called the feeden The rod 19 is partly i'nclosed by a casing 21, which is provided with a reducer 22. A spring-seat 23 is screwed into the reducer 22, and a packing box or gland 25 is screwed on the spring-seat 23. A spiral spring 26 is mounted on the rod 19' and operates to hold the feeder in a closed position and to force the feeder to cut through the carbid to stop the carbid from falling through the couplings into tliewater in the generator. The spring 26 presses against the seat 23 at one end and against the rear edge of the blade 1S at the other end. The seat 23 may be screwed farther in or farther out of the reducer 22 to regulate the tension of the spring 19. A coupling 27 is screwed on the end of rod 19 for making connection with the links 2S. The casing 21 is made rigid by the brace 29, which may be soldered to the casing IOO IOS

charge 33. The object of this particularlyif too much carbid Should described discharge is that there may be a large escape for the gas to revent explosions e fed to the water in the generator 1. rl`he discharge 33 connects witha large pipe 34, which conducts the gas to the tank 32 and up within the bell j 31 and then down in the gasolene-tank 35.

The tank 35 is used to purify the gas and gasolene, or some suitable liquid is placed in the tank 35 to purify the gas by retaining therein the incombustible matter that may be carried by the gas A smaller vessel 36 is placed within the'tank 35 for the purpose of disintegrating the particles of gas as they come from the generator, so that lthe gas ,will be thoroughly washed or purified. Horizontal partitions 37, of meshed wire, are placed in the vessel 36, so that the gas must rise up through the mesh of the wire and be broken into small ieces or particles. The gas rises up throng the gasolene and passes up within the bell 31.

A The tank 32 is provided with a drain-cock 33. The gasolene vessel 36 is filled by means of a pipe 39, inserted in the gas-bell. This pipe is closed by a cap 4() when not in use for iilling the gasolene vessel. A gage-pipe 41 is provided for determining when the gasolene vessel is full or has sufficient gasolene therein. This pipe is connected with the bottom of the vessel 35, and after extending out of the lower part of the tank 32 lis bent up, extended as high as the vessel 35, and provided with a cap 42. The cap 42 is left off while the vessel 35 is being filled, and

when the gasolene rises to the top of the pipe 41 this indicates that the vessel 35 is full.

The cap 42 can then be screwed on. They may be drawn out of the vessel 35 by means of a cock 43, connected with the pipe 41. The gas may be siphoned back into the generator from the gas-bell by means of a pipe 44 which projects above the water-line in the gas-bell and leaves the gas-bell below gasolene the bottom rim thereof and extends out of the tank 32 and connects with the pipe 34. The pipe 44 is provided with a cut-off valve 45, whichv normally closes the pipe 44. the gas-bell is full of gas, the water in the generator 1 may be drawn out and tne cock `or valve 45 opened. The gas in the bell will pass back t0 the generator under these conditions. The pipe 34 is provided with a petcock 46 for drawing out any water that may accumulate in the pipe y34. The gas-bell is provided with a safety-valve or blow-off consisting of a pipe 47, which projects far above the water-line in the gas-bell and extends out ofthe tank 32. The gas-bell 31 carriesa pipe 43, attached to the highest part of the interior thereof and telescopes over the pipe 47 andr extends far below the water-line in the gas-bell. If the gas-bell rises high enough to draw the pipe 43 out of the water, gas will escape down the pipe 47 until the pipe 43 again goes down into the water. The gas may be taken from the gas-bell by means of a pipe 49, which leaves the gas-bell below the bottom thereof and leaves the tank 32 and extends upto the drier 50, from which it may be carried away by the pipe 51. Another safety-valve is provided, and this consists of a pipe 52, which is connected with the pipe 49 and extends near the bottom of tank 53 of water.

The lever 30 is actuated by the fall of the gas-bell 31. When the gas-bell descends, it will pull on the lever 30 by reason of the chain 54, which is connected to the lever and to the gas-bell. The lever 30 has a jointed arm 55,

which will break upward, but not downward.

lever draws plunger-rod 19 against the tension of the spring 26, and thus opens the cuto' valve 13. When the bell ceases to pull on the lever 30, the spring 19 will close the valve 13. Whenever the gas-bell causes the valve 13 to be opened, carbid will fall into the water in generator 1 and gas will be generated immediately, and the gas will cause the gasbell to rise, so that the spring 26 will close the cut-off valve 13.' The lever 30 is jointed, so that if the gas-bell should come in contact with the lever it would not break the lever. The lever would simply break upward and would resume its normal position, when the bell should go down.
