PATENT I DENNIE M. DORMAN, OE BINGHAMTON, NE1V YORK.

ACETYLENE-GAS GENERATOR.

SPECIFICATiQN forming part of Letters Patent No. 634,401, dated October 3, 1899. Application filed January '7, 1899. $erial No. 701,479. (No model.)

To all whom it may concern:

Be it known that I, DENNIE M. DORMAN, a citizen of the United States, residing at Binghamton, in the county of Brooms and State of New York, have invented new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

My invention relates to an improved acetylene-gas generator.

An object of my invention is to provide improved means for discharging given quantities of carbid into the generating-chamber.

A further object of the invention is to provide improved means automatically operated to discharge given quantities of carbid into the generating-chamber at intervals determined by the consumption of the gas generated.

A still further object of the invention relates to certain details of construction and operation of the parts whereby I aim tojproduce a compact, simple, and easily-operated device of the character indicated.

I have illustrated my invention in the accompanying drawings, in which- Figure 1 is a view in side elevation of the complete device. Fig. 2 is a longitudinal sectional view, and Fig. 3 is a detail view of one of the cartridge-shells.

The numeral 1 indicates the outer shell or casing of the apparatus, which in conjunction with a bell 2, mounted ,in the casing 1 in the usual manner, affords in its upper por- In the lower portion of the tion a gas-holder. casing 1 is located a closed receptacle 3, adapted to contain water and affording a generating -chamber, which is secured to the side wall of the casing in any suitable manner and from the upper side of which apipe l extends to the top of the gas-holder for conveying the generated gas thereto. Located in the pipe 4 is a valve 5, suitably operated from a handle 6 to close communication between the gasholder and generating-chamber.

The numeral 7 indicates a supply-pipe leading from the top of the gas-holder to convey the gas to the bu'rners.- Leading from the bottom of the generating-chamber 3 and extending through the casing 1 is a pipe 8, having a valve 9, by opening which valve the pressure of the gas may be utilized to discharge the spent carbid from the generating-chamber.

The numeral 11 indicates a chute, the bottom of which is secured upon and communicates with a curved branch pipe or conduit 12, bolted to the casing near the bottom there of and communicating through the casing and the wall of the generating-chamber with the interior of the latter. The water in the generating-chamber riseshigh enough in the pipe 12, as shown, to afford a liquid seal. A-pipe 13, having a valve 14:, affords means for supplying water to the generating-chamber. I have shown in Fig. 1 the chute 11 as being inclined for the purpose of accommodating a larger number of cartridges where the height of the chamber in which the apparatus may be located is not sufficient to permit the chute to rise the requisite distance. In either case the top of the chute is hermetically closed by a suitable cover 15.

The numeral 16 indicates a screen secured above the bottom of the generating-chamber to support the cartridges above the spent carbid, which settles in the bottom of said chamber.

Rotatably mounted in the bottom of chute 11 by means of journals 18 is a half-round bucket or receptacle 19, which is of a size to receive a shell 17 and the opening 20 of which is designed to be turned by the mechanism now to be described to a position to receive the lowermost cartridge in the chute and then to a position to discharge the same into the pipe or conduit 12; Secured on the outer end of a journal 18 at the outer side of chute 11 is a pinion 21, which meshes with a rack 22, provided at the lower end of a bar 23. Atits upper end the bar 23 is provided with a number of apertures 24, by means of which it may be adjustably secured to an arm 25, carried by the bell 2. A series of guides 10, secured on the casing 1, guides the arm 23 as it is carried up and down by the movement of the bell. It will be seen that as the bell 2 rises or falls the corresponding movement of the arm 23 will, through the medium of rack 22 and pinion 21, revolve or turn the bucket 19 inone direction or the other.. The adjustment of this arm with the bell is such thatas the gasis consumed and the bell falls a predetermined distance, at which point a fresh generation of gas will be required, the

bucket 19 will be turned to bringits opening" 20 over the opening in pipe 12,whereby a shell 17, containing earbid, may be discharged into the generating-chamber 3. As gas generates the bell rises and the bucket 19 is turned in the reverse direction to bring its opening 20 in a position to receive a fresh cartridge.

While I have shown no means for limiting the upward movement of bell 2, it is obvious that any well-known means may be employed to prevent the rise of the bell beyond a predetermined point.

The shells 17 are of metal and are in the form of cylinders having open ends. After a shell 17 has been packed with carbid its ends are closed by means of metal disks 26, inserted therein, which are of a size to be held in the shell by frictional engagement therewith. These disks are connected by a chain 27, extending through the shell 17 and somewhat longer than the shell, and each disk is provided with an aperture 28, through which water can enter to the carbid. As the water contacts with the earbid in the shell the gas generated will blow the disks out of the shell; but the chain 27 will hold the disks and prevent them from being disconnected entirely from their shell.

The numeral 29 indicates a manhole, by means of which access may be hadto the generating-chamber to remove the shells therefrom. Before the manhole is opened the valve 5 in pipe I would of course be closed.

Having thus fullydeseribed my invention, what I claim as new is 1. In an acetylene-gas generator, the COIIlbination with a generating-chamber, of a gasholder having a movable hell, a chute having communication with said generating-chamber and adapted to contain a number of carbid-cartridges, a bucket journaled in the bottom of said chute, a pinion secured on the journal of said bucket and a rack-bar carried by said bell and meshing with said pinion, the combination operating as set forth.

2. In an acetylene-gas generator, the combination with a generating-chamber, of a gasholder having a movable bell, a chute having communication with said generating-chamber and adapted to contain a number of earbid-eartridges, a bucket journaled in the botjournal of said bucket and a rack-bar carried by and having adjustable connection with said bell and meshing with said pinion, the combination operating as set forth.

3. In an acetylene-gas generator, the combination with a casing having a generatingchamber in its lower portion, of a movable bell mounted in said casing and affording, in connection therewith, a gas-holder, a valved pipe affording communication between said i generating-chamber and bell, an upwardlycurved pipe or conduit secured to said casing and communicating through the same with the generating-chamber, whereby the water in said generating-chamber will rise in said pipe or conduit to afford a liquid seal, a chute secured to and communicating with said pipe or conduit, a bucket journaled in the lower part of said chute, a pinion secured to the journal of said bucket andarack-bar carried by said bell and meshing with said pinion, the combination operating as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
