SPECIFICATION forming part of Letters Patent No. 692,745,dated February 4, 1902.-

Application filed July 8,1901.

To all whom it may concern:

Be it known that we, EMANUEL LEOPOLD WEIL and THOMAS WALSTON EVANS, citizens of the-United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Acetylene-Gas Machines, of which the following is a specification.

Our invention relates to acetylene-gas production, and contemplates the provision of an acetylene-gas machine which, while simple and inexpensive in construction and embodying no parts that are liable to get out of order after a short period of use, is automatic in action, and consequently requires but a minimum amount of attention from an at tendant. I

With the foregoing in mind the invention will be fully understood from the following description and claims, when taken in conjunction with the'accompanyingdrawings, in which- 4 p Figure 1 is a side elevation of our improved machine with some of the elements partly broken away and others in vertical section. Fig.2 is a horizontal section taken in the plane indicated by the line 2 20f Fig. 1. Fig.

3 is an end elevation of' the machine with the pipe for supplying water to the generator in section. Fig. 4 is a vertical section taken in the plane at the inner side of one of the disks of the carbid-wheel. Fig. 5 is a perspective view of one of the buckets of said wheel removed. Fig. 6 is a detail section, on an enlarged scale, illustrating the preferred man nor of fixingthe carbid-wheel on the shaft; and Fig. '7 is an enlarged sectional perspective View of the cap-nut hereinafter referred to in detail.

In the said drawings similar letters of reference designate corresponding parts in all of the several views, referring to which A is the gasometer of our improved machine, which comprises a tank a, designed to be filled with water to about the height shown, and the usual vertically-movable water-bell b.

B is a service-pipe which extends from a point above the water in the tank a down through the bottom of said tank and thence to the point at which it is desired to use the gas.

.ranged in the said casing.

Serial No. 67,494. on model.)

C is agenerator having a pipe 0', provided .with a cook or non-return valve d, whereby it may be filled with water when necessary, and also having a gate-valve e for facilitating the removal of debris, and D is apipe for conveying gas from the generator to the gasometer, said pipeextending through the botvided at theirelbows below the tank a with 'cocksf, through which water may be drained from'thelnat intervals.

E is a casing disposed above and connected to the generator 0 and provided with a manhole '9 at its top, and F is a carbid-wheel ar- The carbid-wheel in the preferred embodimentof the inven tion comprises .a central sleeve h, side walls or disks '2', a circular series of transverse bolts connecting said side walls, sleeves k,

surrounding said bolts and interposed between the disks'or walls '5 to hold the same at the proper distance apart and stifi'en and strengthen, the wheel, a circular series of transverse shafts Z, which are journaledin the side walls i and areprovided at one side of the wheel with cranks m, and carbid-receiving buckets n, which have sleeves 1) arranged on and connected by bolts or other suitable means to the shafts l." Asstated, the cranks m on the shafts of the carbid-buckets are disposed at one side of the wheel, and they are arranged to be engaged by a tappet q, arranged in the casing E at a point adjacent to an opening r between the casing E and generator C when the carbid-wheel is rotated in the directionindicated by arrow in Fig. 1. From this it follows that as the buckets approach the opening r they will be automaticallydumped and their contents discharged through a hop-.

per 8, with which the generator is preferably provided, into the water in said generator.

With a View of preventing the passage of gas from the generator into the casing E we provide the trap-door G. This'dooris pivotally connected to the hopper s, at the lower end thereof, and' is provided with an arm t,

carrying a weight u, whereby it is normally held in a closed position for the purpose stated. When, however, a charge of carbid IOO is received on the door from one of the buck ets n, it opens, after the manner shown in Fig. 1, to permit the carbid to pass into the water in the generator, and then automatically closes.

The sleeve h of the carbid-wheel F surrounds and is connected by diametrical bolts or other means to a shaft H, and this shaft is extended through the side walls of the casing E and journaled at one end in a cap-nut 'u, screwed into one side bar of astrengtheningframe I, which surrounds the casing E, as shown. The shaft also extends through a stuffing-box w, connected to the other side bar of the frame I, and is provided within said stuffing-box with a collar w. A screw y, which bears in the cap-nut o and impinges against one end of the shaft H, has for its purpose to bind the collar :1: against the gland j the generator 0, the same may be readily accomplished by supplying the said generator of the stuffing-box w, and thereby subject the shaft to friction, so that the wheel will not casually turn when but a portion of the buckets n are filled with carbid.

One end of the shaft H is extended a considerable distance beyond the casing E and frame I and is provided with a ratchet-disk J. This disk is designed to be engaged by a pawl ,2, carried by a lever K, which lever has an open portion a fulcrumed on the shaft H and surrounding the ratchet-disk J and also has a counterbalance-weight o mounted on one of its arms, preferably in an adjustable manner. The other arm of the lever K extends through a yoke 0, carried by a rod 61, connected to the water-bell b and movable through a guide 0 on the tank a of the gasometer. By virtue of this construction it will be observed that when gas is taken from the gasometer and the water-bell b descends in consequence the lever K will be rocked in the direction indicated by arrow in Fig. 1 and the carbid-wheel will be turned in the same direction to carry the crank m of one carbidbucket into engagement with the tappet q, when the bucket will be dumped and its contents discharged past the trap-door G into the water in generator 0. This will result in the generation of a fresh supply of gas in the generator, and such gas passing through the pipe D into the gasometer will raise the waterbell of the latter to its normal position. Incident to the raising of the water-bell the counterbalance-weight 11 will rock the lever K in the direction opposite to that indicated by arrow to carry the pawl 2 into engagement with the next upper tooth of the ratchet-disk J so that when gas is again taken from the gasometer and the water-bell b descends the carbidwheel will be again rotated to effect the dumpin g of the carbid-bucket in rear of that before mentioned and the generation of a fresh supply of gas. This operation will continue until all of the several buckets of the carbid-wheel have been discharged of their contents.

In order to charge or place carbid in the buckets n of the carbid-wheel, the attendant has but to open the manhole g at the top of the casing E, disengage pawl z from disk J, and slowly turn the wheel F in the direction opposite to that indicated by arrow and fill the buckets as they come beneath the manhole. Then the wheel is turned in the direction opposite to that indicated by arrow, the cranks on the buckets will ride over the tappet q in said direction; but the filled buckets, by reason of their construction, (see Fig. 5,) will not be discharged of their contents.

The generator 0 is supplied with water through the pipe 0, the cock d being of course opened precedent to the filling operation and closed subsequent to the same, so as to prevent the escape of gas through the pipe. When desired a check or non-return valve may be employed in lieu of the cock (1 without departing from the scope of myinvention.

When it is desired to remove debris from with water and opening the gate-valve e at the bottom of the same.

It will be readily appreciated from the foregoing that while our improved machine is simple and inexpensive in construction and embodies no parts that are liable to-get out of order after a short period of use, it is automatic in operation, the attendant having but to fill the generator C and replenish the supply of carbid in the buckets n at intervals.

We have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiment of our invention in order to impart a full, clear, and exact understanding of the same. We do not desire, however, to be understood as confining ourselves to such specific construction and relative arrangementof parts, as such changes or modifications may be made in practice as fairly fall within the scope of our claims.
