ACETYLENE-GAS GENERATOR.
Specification of Letters Patent.
Patented July 18, 1916.
Application filed May 18, 1915. Serial No. 28,904.
To all whom it may concern Be it known that I, DANIEL B. HILL, a
citizen of the United States, residing at.
feed carbid to the generating vessel as the same is wanted and which is also ,provided with automatically operating means for supplying the feed hopper with carbid.
The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.
In the accompanying drawings :Figure 1 is a vertical central sectional view of an acetylene gas generator constructed in accordance with my invention and showing the gas bell in raised position and the feed valve closed. Fig. 2 is a detail horizontal sectional view on the plane indicated by the line 22 of Fig. 1, the cross bar being omitted. Fig. 8 is a similar view on the plane indicated by the line 33 of Fig. 1. Fig.
4 is a detail plan of the fixed valve disk.-
Fig. 5 is a detail horizontal sectional view on the plane indicated by the line 55 of Fig. 1, looking in the direction indicated by the arrow.
The tank 1,.which forms a generating chamber, has a gas feed pipe or surface pipe 2 leading therefrom and the tank is provided with a removable cover 3 which may be secured in place by any suitable means. An annular wall 4 is on the inner side of the tank 1, spaced therefrom, and arranged at a suitable distance from the upper end of said tank, said annular wall and the wall of the tank forming a sealing chamber 5. A gas bell 6 is arranged in the upper portion of the tank and is sealed in the water in the sealing chamber. A feed hopper 7 is arranged within the wall 4 and is provided at its center with a downwardly extending spout or discharge neck 8 in which is a fixed valve disk 9 which is provided with feed openings 10.
A tubular standard 11 rises from and is secured to the fixed valve disk 9 and is provided at its upper end with a covered fixed cylindrical casing 12in the top of the tank, and which has a noncircular opening 13 in the cover. A cross bar 14 is arranged in the casing at a suitable distance from its upper end. A shaft 15 extends through the tubular standard, has its lower end stepped on a bearing 16 which is supported at the lower end of the spout 8, and said shaft is also provided at'its lower end with a valve disk 17 secured thereto and adapted to turn therewith, said disk being provided with openings 18 which may be moved into or out of registry with the openings 10 of the fixed disk 9. At the upper end of the shaft is a hollow cylindrical drum' 19 the wall of which is provided, in opposite sides, wit
cam slots 20.
A non-circular operating shaft 21 of same cross section as. the opening 13 is guided for vertical movement in and through the opening 13, has a head 22 at its engaged in the cam slots20. A coiled spring 25 is arranged around the shaft 21, its
lower end bearing on thecross bar 14 and its upper end engagingastop device 26 with which the shaft'21 is provided. Said spring serves to normally move the shaft 21 together with its disk '23 upwardly and to keep the cam studs 24 in'the upper end of the cam slots 20 and normally hold the valve disk 17 with its'openings 18 out of registry with the openings 10 of the disk9 and therebynormally cut off the supply of carbid from the hopper to the generating chamber. 1
In the operation of my improved acetylene gas generator, when the gas bell dcscends owing to the consumption of gas from the generator, the top of the bell bears on the upper end of the shaft 21 sothat said shaft moves downwardly, against the tension of its spring 25, with the bell thus causing the cam studs 24 which move clownsure increases the bell rises, permitting the shaft 21 to be moved upwardly by the spring 25 and hence causing the valve disk 17 to be partly reversely turned and cut off the supply of carbid to the generator.
To automatically supply the hopper with carbid when the main supply is exhausted and hence enable the apparatus to continue automatically in operation for a considerable period of time I provide a reservoir chamber 27 which is here shown as arranged in one side of the hopper, which is adapted to contain a supply of carbid and is provided with a vertically movable gate, door or valve 28 in one side. A bent lever 29 is pivotally mounted on the reservoir chamber as at 30 and has its longitudinal arm 31 connected by a suitable chain 32 to the gate or valve 28 and has its vertical arm 33 provided at its upper end with a head 34. This head is at a lower level than the lowerlimit of the head 22. Ordinarily the bell does not descend so low as to strike the head 34. lVhen, however, the carbid in the hopper has been all exhausted, and the bell is in its lowest position, the top wall of the bell is about one-eighth of an inch above the head 34: of the arm 33. lVhen the bell is in this position, and by removing the cover 3, a downward pressure may be applied to the bell at a point directly above the head 34. This pressure will tilt the bell and cause its top wall to engage and move the head 34 downwardly, resulting in the opening of the valve 28. As soon as the valve 28 is opened, the carbid in the chamber 27 will fall into the hopper 7. After the pressure has been removed therefrom, the bell will return to its normal position, and the valve 28 will close. As the bell is still in its lowest position, and the openings 10 in registration with the openings 18, a charge of carbid will be fed from the hopper 7 to the generating tank or chamber.
Having thus described my invention, I claim 1. In an acetylene gas generator, a generating tank, a carbid feed hopper having a downwardly extending discharge spout, a fixed valve disk having openings and arranged in said spout, a valve disk pivotally mounted in said spout under said fixed disk and having openings movable into and out of registry with those of the fixed disk, a shaftrising from the center of said pivotally mounted valve disk, a drum at the upper end of said shaft and having a cam slot, a tubular standard rising from and seoured to the fixed disk and providedat its upper end with a fixed casing in which said drum is rotatably arranged, a vertically movable shaft arranged in said casing extending above the upper end thereof and having a cam stud engaging said cam slot of the drum, means to prevent the rotation of said vertically movable shaft, a gas bell to depress said shaft when the bell lowers and thereby turn the drum and movable valve disk and cause the openings of the latter to register with those of the fixed valve disk and a spring to move said vertically movable shaft upwardly when the bell rises.
2. In an acetylene gas generator, a generating tank, a carbid feed hopper having a discharge spout, a fixed valve disk having openings and arranged in said spout, a valve disk rotatably mounted in said spout and having openings movable into and out of registration with the openings of the fixed disk, a shaft rising from the center of said rotatably mounted valve disk, a drum at the upper end of said shaft and having a cam slot, a. shaft adapted to be moved vertically with relation to said drum and having a cam stud engaging said cam slot, means to prevent the rotation of said vertically movable shaft, a gas bell adapted to engage and move said shaft downwardly with relation to said drum when the gas pressure in the generating tank falls below a predetermined degree, and a spring engaging said shaft and adapted to move it upwardly with relation to said drumv when the gas pressure in the generating tank elevates the bell.
In testimony whereof I afiix my signature in presence of two witnesses.
