UNTTE STATES REINHOLD A. CARL, OF ELGIN, TEXAS.

ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented June 5, 1906.

Application filed J1me 1905- Serial 267,020.

To aZZ whom, it may concern:

Be it known that I, REINHOLD A. CARL, a citizen of the United States, residing at Elgin, in the county of Bastrop and State of Texas, have invented a new and useful Acetylene- Gas Generator, of which the following is a specification.

This invention relates to acetylene-gas generators, and has for one of its objects to provide an acetylene-gas apparatus in which the parts may be readily detached for convenlence in making rep airs.

A further object of the invention is to provide a 'novel form of generating-tank so arranged that the upper section or cover may be readily removed when necessary and which may be retained in place without the employment of packing and without using rivets, bolts, or other securing devices.

A still further object of the inventionis to simplify and improve the construction of the valve mechanism to permit the ready adjustment of the valve to position when the machine is being made and its ready removal for examination or repairs when necessary.

A still further object of the invention is to provide a novel form of carbid-holder and to so arrange the same as to permit replenishing of the supply in the holder from time to time, and, further, to provide a water-seal cap or cover for said carbid-receptacle.

A still further object of the invention is to provide a novel mechanism for automatically actuating the carbid-valve directly from the movable bell of the gasometer and to effectively seal the various connections between the generating-tank and the gasometer without interfering with the free movement of the bell of the latter.

A still further object of the invention is to provide a ready means for replenishing and maintaining a constant level of water in both the gasometer and the generating-tank, it being necessary to supply only the gasometertank and the overflow from the latter passing to the generating-tank.

With these and other objects in view, as

' will more fully hereinafter appear, the invention consists in certain novel features of construction and arran ement of arts hereinafter fully described, illustrated 1n the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a vertical section of an acetylene-gas apparatus constructed in accordance with the lnvention. Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of a ortion of the cap of the carbid-holder and t e means for looking the same in position.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the. drawings.

The generating-tank 10 may be of any desired size and is provided with a slightly-inclined bottom 11. From the lower portion of the tank leads a slush-discharge pipe 18, having a suitable valve, which when open will permit of the discharge of the slush and water from the tank. Fitting within the tank is a pendent flange 14 of a removable cover 15, the latter having an annular flange that rests directly on top of the tank roper, while the flange is sealed in water wit in the tank, it being unnecessary to employ any packing or any means, such as bolts or rivets, for securing the cover in lace.

The central ortion o the cover 15 is provided with a anged opening for the reception of a frusto-conical carbid-holder 16, the lower portion of which extends within the tank and is provided with a detachable flange-seat 17, that may be readily removed when the valve is to be examined or repaired. Within the carbid-holder is a verticallyedisposed guiding-tube 18, held in place by suit able arms 19 and receiving the upper end of a 5 I valve-rod 20. This rod carries a conical valve 21 within the carbid-holder and is further provided with a conical scattering-disk 22 for distributing the carbid as it falls from the holder. is connected to one end of a lever 23', fulcrumed on a cross-bar 24, that is carried by ears depending from the flange 14, and the opposite end of said lever is connected to a vertically-disposed bar 25, that extends upward through a sealing-tube 26, that passes from a point below the water-line of the generating-tank to approximately the top of the bell 28 of the gasometer. This tube also passes through the carbid-holder and serves as a means for locking the same in place.

Mounted on top of the carbid-holder is the tank 30 of the gasometer, and projecting from The lower end of the valve-rod one side of the tank is a filling-lip 31, into the escape of the gas.

which water may be poured and the water passing into the tank through an openin 32 in the side wall of said tank. EXtenc ing through the bottom of the filling-lip is a vertically-disposed tube 33, the top of which is open andforms an overflow for surplus water, said water passing down into a lower enlarged tube 34, that communicates with the discharge-pipe leading from the reservoir at a point'to the rear of the discharge-valve. In this pipe 34 is an overflow-nozzle 35 to maintain the correct height of water in the generating-chamber. It will be observed that by pouring water into the lip 31 the tank of the" gasometer may be filled and that the pouringmay continue until some of the wa ter issues from the discharge-pipe 35, the op-. erator'being then notified that-both the gasometer-tank and the generating-tank. have receive'd'proper supplies of water.

Extending upward from the carbid-holder is a: tube 36, open at the top and forming a passage through which carbid may be fed to the holder, and from the top of the carbidholder extends a second tube 37, surrounding the first and slightly spaced therefrom to form an annular water-space 38, which is filled with water and receives the lower open end ofa .cap 39. This cap 39is-tubular in form, and its lower end being inserted in the water is sealed for the purpose of reventing The top 01 the cap is ofcourse closed. From the opposite sides of-the cap project lugs 40, which are adapted to enter notches 41, formed in an upper flange 42, that extends inward from the upper end of the tube 37, and when once entered in these notches the lugs may be turned, to gether with the cap-piece, in order that the caprmay be firmly locked in place.

The gasometer-tank is provided with a verticallyeXtending tube 44, that projects upward around the tube 37 to a point considerably above the normal level of the gasometerbelll, and'the upper end of this tube is turned inward, as indicated at 45, in order that the water'niay be conveniently introduced into the annular water-space 38. The bell is providedwith a pendent tube 47, that surrounds the outer tube 44 and is sealed in the water of the gasometer-tank in order to prevent the escape of any gas between the tubes 44 and 47.

The upper end of the tube 26, which surrounds the valve-operating rod 25, is threaded and carries a pendent tube 50, that is sealed'in the water of the gasometer, said tube being tapered and of greater diameter at its lower than at its upper end. This tube 50' extends over a smaller tapered tube 51, that is carried by the gasometer-tank, and the upper end of this tube 51 projects above thewater-level of the gasometer-tank. The 'gasometer-bell' carries a tapered tube 52, which surrounds the tapered tube 50 and is also sealed in the'water of the gasometer, the

i several tubes positively preventing the escape of any gas and being tapering permitting the rise and fall of the gasometer-bell without undue friction.

Secured to the top of the gasometer-bell is a valve-operating bar or cap 56, which when the gasometer-bell descends engages the top of the valve-operating rod and by depressing the same moves the valve 21 upward and allows carbid to flow from the holder into the generating-tank. When the bell rises from the gas generated, the valve will close.

The gas generated within the tank is led upward through a pipe 57, which passes also through the carbid-holder and is discharged at the upper portion of the gasometer-bell. Secured to this pipe is the upper end of a tube 58, which gradually increases in diameter toward its lower end, and said lower end is sealed in the water of the gasometer. tube 58 surrounds a second tapered tube 59, that is carried by the gasometer-tank, its upper end opening within the tube 58 at a pointabove the water-line, thus forming a seal to prevent the escape of gas.

At one side of the gasometer is afilter, which in the present instance includes a lower tank 60, open at the top and provided with awaterfilling spout 61 and an overflow 62. This tank receives abell 63, the lower end of which is sealed by the water, and from the upper end of this bell leads a service-pipe 64. VVithin the bell is arranged a cylindrical casing 65, that is divided into upper and lower' compartments by a transversely-disposed partition 66, and immediately above the partition is a conical shield 67, surrounding the mouth of the gas-pipe 68, that leads from a point above the water-level of the gasometer, and gas discharged through this pipe will be deflected by the shield and thence will pass upward through a filtering medium 69, which may be in the form of cotton or other suitable material.

The pipe 68 is connected to a pipe 70, the lower end of which extends below the waterline in the tank 60, and in case of excess gas the surplus will flow through the pipe 70 and thence pass out through the discharge-pipe 71, that is connected to a pipe 72, leading to a point outside the building in which the generator is arranged. This pipe 72 is connected to the generating-tank by a pipe 73, having a suitable valve 75, so that when the tank is to be cleaned the valve may be opened and the gas within the tank discharged.

With an apparatus constructed in accordance with this invention the manufacture of gas may be carried on automatically, fresh supplies of carbid being introduced into the generating-tank each time the bell descends and the valve automatically closing each time the bell ascends. Owing tothe arrangement of the several sealingtubes,it is impossible for any gas to escape from the gasome- The ter or from the tank. The arrangement of the gasometer overflow-supply permits of the convenient filling of the gasometer-tank and the generating-tank and all parts are in constant view, so that the operator may be informed when the proper quantity of water has been supplied to both tanks.
