WVILLIAM A. (i-RIBBLE, OF COLLlNSVlLLE, TEXAS.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 783,947, dated February 28, 1905.

Application filed June 14,1904. Serial No. 212,539.

To all who/r1. it may concern;

Be it known that 1, WILLIAM A. Germans, a citizen of the United States, residing at Collinsville, in the county of (irrayson and State of Texas, have invented certain new and useful Improvements in Acetylene ti'ras Generators, of which the following is a specification.

The object of my invention is to provide a novel construction of gas-generating machine which is composed primarily of a single main receptacle having a generating-chamber, carbid-holder, valve mechanism controlling the feed of the carbid to the generatirig-chamber, and a gas-bell mounted upon the generator and connected with the valve mechanism aforesaid for operation thereof. The gas-space of the generating-chamber communicates with the gas-space of the gas-bell directly, and because of the arrangement of the generator with reference to the carbid-holder and bell the whole machine is made in very compact form.

The invention obviates the necessity of use of a generator and a separate gasometer having numerous intermediate connections and gas-controlling means, thereby greatly cheapening the cost of the generator and increasing the general desirability of my structure.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a vertical sectional view of a gas-generating machine embodying my invention. Fig. 2 is a horizontal section on the line X X of Fig. 1. Fig. 3 is a horizontal section on the line Y Y of Fig. 1.

Correspomling and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Describing and designating the essential features of my invention structurally, my machine COIHPI'iSGS prii'icipally a generator 1,

which consists of a tank of suitable size governed chiefly by the amount of gas tobe produced by the machine, and the carbid-holder 2 is disposed at the upper portion of the generator. The generator 1 is designed to receive water, within which the carbid is projected upon operation of the valve mechanism, and at the upper end of the generator-receptacle 1 and sliu'rounding same, preferably, is located the gas-bell 3. The upper end of the generator 1 is reduced diametrically, and the reduced portion, which is indicated at 1", is received within the gas-bell 3, as clearly shown in Fig. 1. The upper end of the generator 1 is open, so that the gas-space within the generator d irectly communicates with the gas-space of the hell 3, and the decrease and increase of the gaspressure within the generator will induce the necessary responsive action of the bell and op eration of the valve mechanism operated by said bell and by which the feed of carbid is regulated.

The carbidreceptacle 2 is of a suitable form for the purpose of the invention, being somewhat cone-shaped at its lower end, as shown at 2, so that the carbid will :feed regularly and to prevent formation of dead space within which the carbid might accumulate. Within the holder 2 is disposed a casingt, closed at its upper end, and the valve 5 operates within the casing, being movable toward and from a seat 6 adjacent the opening 7 in the lower end of the carhid-holder 2. The valve is protected by the cesing 4 from the carbid within the holder, said casing being disposed slightly above the lower end of the holder and supported by suitable supports or wings 8,-

resting upon the portion 2 of the carbid-receptacle. The valve 5 is operated directly by a rod 9, connected at its lower end to one end of a pivoted lever 10, and. a second valverod 11 connects the other end of the lever 10 with the gas-bell 3. The upper end of the rod 11 is the part thereof which is actuated by the hell 3, said rod 11 passing through a guide member, (indicated at 12.) The valve-rod 11. is guided in its vertical movement by a guide-tube 13, and in order that the vertical movement of the gas-bell 3 may be uniform and to prevent binding of the bell in such movement a guidebar 14 is projected upwardly from the generator at a point approximately opposite to that part of the generator adjacent which the rod 11 moves, said guide-bar let passing through a second guide member 15, extending laterally from the upper portion of the bell 3.

of the genportion in Upon the reduced upper end 1 erator 1 and surrounding said spaced relation thereto is a shell 16, which forms an annular chamber around the generator, said chamber receiving a liquid to form the necessary liquid seal between the hell 3 and the generator. A guide-tube 13 is attached to the outer portion of the shell, above described. The location of the shell 16 is such that the compactness of the arrangement of the parts of the machine is promoted.

The lever 10 within the generator 1 is pivoted to a horizontal service-pipe 17, which is located transversely of the lower portion of the generator, said service-pipe being provided with a vertical support 18, to which the lever 10 is directly fulcrumed. The servicepipe 17 extends out of the generator to any suitable point. The vertical supply-pipe 19 extends upwardly from the portion of the service-pipe 17 disposed within the generator, the upper end of the said pipe 19 being projected into the gas-space within the generator.

Suitable caps 20 and 21 are provided upon the bell 3 and the carbid-holder 2, respectively, and these caps may be removed or replaced for obvious purposes. Lugs 22 or other suitable means may be projected from the upper portion of the carbid-holder to support same in the upper portion of the generator.

The vertical stand-pipe 27 is shown in dotted lines in Fig. 1, and this pipe may be of any suitable form, being preferably adapted to turn down in order to draw off the residuum which may have collected in the bottom of the generator. The lower end of the standpipe 27 is connected with the lower end of the generator by any suitable coupling. The service-pipe 17 is provided in its length with a drier 28, which commonly used for this purpose, and a dri receptacle 29 is connected with the lower end of the drier 28.

In order to set up and agitate the residuum in the generator preparatory to drawing 05 of the same, an agitating-arm 23 is disposed horizontally in the lower portion of the generator and said arm is actuated bymeans of a vertical rod 24, projecting upwardly therefrom. The vertical rod 2 passes through the guide-tube l3 and is with a handle 25.

A cotter-pin 26 is provided adjacent the upper end of the valve-rod l1, and this pin is provided at its upper end may be of any suitable type I adapted to be engaged by the adjacent guide member 12 in the downward movement of the bell 3. The engagement of the member 12 with the cotter-pin actuates the rod 11 so as to open the valve 5 to thereby admit of passage of the carbid from the holder 2 into the generator 1.

In its practical operation the variation in pressure of the gas within the generator 1 'etfects the operation of the gas-bell 3, reduction of such pressure causing the said bell to lower, and this movement effects engagement of the guide member 12 with the cotter-pin 26, thus causing the valve 5 to move away from its seat. Carbid is thus fed into the generator-chamber and the increase of pres: sure in said generator raises the gas-bell and the member 12 moves out of engagement with the cotter-pin, thereby shutting off the flow of carbid due to seating of the valve5.

Having thus described the invention, what is claimed as new is- In an acetylene-gas generator, the combination of a generator having its upper portion reduced, a shell surrounding the upper portion of the generator and forminga liquidchamber, a bell having its lower end received in the liquid-chamber aforesaid, a carbidholder mounted in the upper portion of the generator, a valve controlling the feed of carbid from said holder, a service-pipe disposed transversely in the lower portion of the generator, a vertical supply-pipe leading from the gas-space of the generator into the servicepipe, a lever pivoted to the horizontal servicepipe in the generator, a rod connecting one end of the lever with the valve, a second rod connected at its lower end with the other end of the lever and having its upper end projected out of the generator alongside of the gas-bell, a guidetube secured to the shell aforesaid and receiving the valve-rod adjacent the bell, a guide-bar projected upwardly from the generator at the side opposite that upon which the last-mentioned valve-rod is disposed, guide members projected laterally from the upper portion of the bell and cooperating with the guide-bar and last-mentioned valve-rod to direct the movement of the bell, and a pin extended from the upper end portion of the lastmentioned valve-rod and adapted to be engaged by the adjacent guide member of the bell to effect actuation of the valve.

In testimony whereof I afiiX my signature in presence of two witnesses.
