UNITED STATES PATENT OFFICE. I ALBERT F. CHAOE, or BOSTON, MASSACHUSETTS.

ACETYLEItE-GAS GENERATOR.

To all whom it may concern.-

Be it known that I, ALBERT F. CHAOE, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Im rovements in Acetylene-Generators, of which the following is a specification.

' This invention has for its object to provide an apparatus which shall be entirely safe in its operation-and can be used for generating and storing acetylene as in a'considerable volume or quantity un er sufiicient pressure to enable the apparatus to be used for charging lamp and other reservoirs with compressed gas or to enable the gas to be supplied through suitable pressure regulating and governing devices to burners.

The invention consists in the improvements which I will now proceed to describe and claim. I I g Of the accompanying drawings, forming a part of this s ecification, Figure 1 represents a side elevation of an apparatus embodying my invention. Fi 2 represents a top plan view of a portion 0 the apparatus.

The same reference characters indicate the I same parts in all the figures.

I main pipe 14 and branches 15, connecting the In the drawings, 12 represents a receiver, which is preferably a cylindrical vessel of fixed capacity and, composed of 'metallic plates securely riveted together and of such strength as to be able to resist a relativel' high pressure, such as two hundred poun s 13 13 represent a series of enerators connected with the receiver 12 y means of a main pipe with each of'the generators. The generators are adapted to contain charges-of calcium ,carbid, and the combined capacity of the series of generators is such that the reaction of water on the charges in all the gen.-

.cover 16 for ear openin erators will create sufiicient gas to fill the receiver at the predetermined pressure. Each generator isprovided with a carbid-receiving opening at its up or end and with a movable The generators should be of such strengt thatthey are capable of resisting the same pressure as the receiver12.

17 re resents a Water-reservoir, which is subdivi ed into a series of compartments 18 18, the number of. compartments being the a same as the number of generators, each compartment bemgponnected with a co'rres ond- Specification a Letters Patent. Application filed April 3,1905. Serial No. 253,397.

y a pipe 19, which de 'vers Patented July e1, 1906.

water to a perforated annular distributingpipe within the generator. Each compartment of the water-reservoir contains the eX- act quantity of water re uired to'react upon the charge of carbid hel by the corresponding generator. The compartments 18 are open at the u per end of the reservoir, so that they are all filled through a feed-pipe 21, entering the upper portion of the reservoircasing, the water fiowin first into one compartment and then over owing into the other compartments until all are filled. A wastecock 22 is or may be provided at the upper 'ortion of the reservoir for the escape of surace water above the compartment 18. The feed-pipe 21 is provided with a cook 23, by which 1t may be closed. Each of the pipes 19, connecting the reservoir-com artments with the generators, is also provi ed with a closing-cock 24'. The pipe or conduit 14,

connecting the generators with the gas-receiver, is provided with a check-valve 25, adapted to open toward the receiver and from the generators, so that while the checkvalve permits the free passage ofgas from -the generators to the receiver it prevents the backward passage from the receiver to the generators. The conduit 14 is provided with a shut-off cook 26 between the checkvalve 25 and the receiver 12.

' 27 represents apipe-forming a part of a connectionbetween the-conduit 14 and the top of the water-reservoir, the remaining part of said connection being provided. by a pipe 28, of which the pipe 27 is a'branch, said pipe 28 communicating with the conduit 14 and with a suitable pressure-regulator 29 and a governor 30. A distributing-pipe 31 exprovided in the conduit 14- between the ranch 28 and the generators. Theapparatus may be operated as follows: The generators 13 being charged with carbid and the reservoir-compartments 18 with Water, the water is allowed to pass either from one compartment to the corresponding generator or from all the compart-' ments simultaneously, to the gpnerat'or's with which they are connected. water reacting on the carbid .in the accom- I I O ach charge of water from entering the enerators, but when i action and production of gas.

panying generators exhausts the-charge of carbid, e gas passing to the receiver; Each generator is filled partly b the charge of water flowing into it from t water-re:

must be left open in order to vent and per-.

mit a free flow of Water from the reservoir to the generators. When the cock 34 is closed while the gas is being generated, pressure of the gas in the generator will prevent the the cock 34'is opened t e gas-pressure from the receiver acting on the surface of the water will counterbalance the pressure in the generators and permit water to flow by gravitation from the Water-reservoir to the generators, and thus insure a continuous re- While the receiver is being charged the stop-cock 35 in the su ply-pipe 28 may be closed until-the desire pressure has accumulated inthe receiver, although this is not essential, as gas may pass from the receiver 12 to the supp pipe 28 from the commencement of the gen erating operation.

The generators are contained in 'a watertank 38, the water inwhich, surrounds the external surfaces of the generators and re vents excessive heat in the generators. ach

generator has a waste-outlet 39at its lowerend through which the residual matter may beforced by gas-pressure or otherwise. Eac

outlet 39 is provided with. a stop-cock 40.

The described apparatus is simple inconstructi'on and safe and efiective in operation;

Owing to the employment of a series of rela-' tively' small generators I am enabled to generate an ample volume of gas without liaen the the water-reservoirs and the generators and then allow the water to fiow to the generators until all the carbid has been exhausted.

- After the receiver has been charged the generators and Water-reservoir may, be cut off from the system until the pressure in the receiver has been reduced by the consumption of gas sufficiently to require a fresh supply.

I claiin 1 An acteylene-gas apparatus comprising a closed water-receptacle, means for supplying Water thereto, a'generator, connections between the receptacle and generator, a gasreceiver, connections between said receiver and generator", and a connection between said gas-receiver and the top of the water-receptacle, said connection being independent of the water-supply connection, whereby, when the receptacle is being filled with water, gas in said receptacle will be forced toward tllile receiver without escaping to the atmosp ere.

12. An acetylene-gels a paratus comprising a tank, a lurality of'in ependent generators situated t 'erein, a water-receptacle containing a-plurality of'compartments each com partlnent being separately'connected to one of the generators,,a gas-receiver, and. connections between each of the generators and gasreceiver and between said receiver and all the compartments of thewater-receptacle.

In testimony whereof I have affixed my signature in presence'o'f two witnesses.
