1 NT FFICE- GAS-CONTROLLER FOR USE WITH GAS-ENGINES.
To all whom it may concern:
Be it known that I, O'r'ro H. WENDnno'rn, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Controllers for Use with Gas-Engines, of which the following is a specification.
This invention relates to safety devices for use with gas engines which take their supply of gas from a gas main or house supply.
The object-of the invention is to provide a device which .will positively prevent the engine from reducing the pressure on the gas main in cases where the engine requires a greater supply of gas at a given pressure than the main may be supplying, in order to prevent robbing the main and lowering the pressure therein, which might cause much trouble to other gas consumers.
A further object is to provide a construction in which the suction of the engine will be prevented from breaking the water seal in case the gas supply on the main is lowered below a predetermined pressure, necessary to properly supply the engine.
Referring to the drawings which form a part of this specification, Figure 1 discloses a vertical sectional view through a machine embodying my invention. Fig. 2 discloses a modified detail of construction.
My construction embodies a very small gasometer of a size depending on the size of the engine employed, and preferably holding just enough gas to properly supply a single charge or two, for each impulse stroke of the engine, and therefore is made of very small capacity compared to other gas holders and may be made at less cost, and to require less space in use.
A, indicates an outer cylindrical shell with a closed bottom A, and B indicates an inner cylindrical shell of sufliciently less diameter to provide an annular chamber C, for holding water D, to form a water seal.
A indicates a funnel shaped portion of a the casing A, provided with a cap A and serves as a conduit through which the chamber D is supplied wit-h water up to the level of the opening A or a short distance above same.
E, indicates a bell of the usual constructionemployed in gasometers, the depending wall of which rests in the chamber C to form an expansible gas chamber F. The

weight of the bell E and parts carried thereby is made such as to give the required pressure on the gas to just balancethe pressure carried on the main G.
Fastened to the bottom A 'of the apparatus is a cylindrical casting H, the lowerend of which may be made integral with the flange H, as shown in Fig. 2, or may be provided with a threaded shank portion H which engages with a thread formed on the inner surface of the flange, and the threaded end of the shank H? projects below the flange and engages with the T I as illustrated. The T I is provided with a threaded nipple I, the top end of which is preferably closed by a plug 1 and the lower end by a cap 1 A j am nut I is used to hold the nipple in its adjusted position. The nipple is adjusted to serve as a throttle for the gas to prevent a too sudden lowering of the pressure in the main when the engine takes gas from with passages J -J to permit the gas to flow into the chamber L in the casting L, which casting is threaded at its lower end to engage with the casting H and holds the guide ring J in position as shown. The top of the castingL is provided with a central perforation L which serves as a guide for the valve rod K, and is also provided with assages L L to pass the gas into chamer F. A valve-seat L is formed on the under side of the top of the casting L, and a valve K is mounted on the rod K and is held against the valve-seat by the spring M, which rests on the ring J and presses the valve against the valve-seat L with sufficient force to hold the valveK to its seat against the weight'of the bell E.
'The valve rod K extends above the top edge of the shell B, so that the said bell may contact with it to depress it under certain conditions. A casting N, is also connected to the bottom A and is the same in construction as that of casting H previously described, and is provided withvthe same character of shank as that indicated by H and a T outlet similar to T I of the inlet, but the nipple I is dispensed with and -ward to, or nearly to the under side of the bell E, and carries a valve R at a predetermined distance above the valve-seat Q.
An abutment ring R is mounted on the rod R within the casting Q and a spring R is interposed between said abutment ring and ring guide P to support the valve R in the normal posit-ion shown. The casing A is provided with a cover A which is secured to the casing bybolts A A and is also provided with a central opening A and a bracket guide A which serves to guide the rod B which is mounted on the bell E and extends upward through the opening A and bracket A and carries a ring S. A rod T is fulcrumed at, T and a pull chain T is connected to its opposite end as illustrated. The arrows indicate the inlet and outlet openings for gas.
The operation is as follows: Assuming the gas inlet connected to a gas main supplying gas under the usual pressure, and the outlet connected to a gas engine, and the device filled with air as it would be just after having been erected in condition for use. A by-pass cock on the engine would be opened and the chain T would be pulled down to force the bell E to open the valve K against the gas pressure on the main and the spring M, thus lowering the valve R toward its valve-seat Q, but not seating said valve. The gas would then flow into and through chamber F and from same through the conduit in the castings G and N and thence to the engine, and when the air had been driven out of the chamber F and pipes leading to the engine, and pure gas filled the chamber F under the same pressure as that on the gas supply main, the gas pressure should just float the bell E, so that normally it would float with the valve K closed and valve R open, substantially as shown in the drawing. Whenthe engine is started the gas is drawn from chamber F, thus lowering the pressure therein and causing the atmospheric pressure on the top of bell E to force the bell down thus overcoming the pressure of the spring M, and admitting gas to chamber F and directly through same to the engine so long as the engine is operating on the suction stroke. As soon as the engine ceases to draw gas from the chamber F, the gas would continue to flow into said chamber until the bell again floated, thus closing valve K. During the operation of the device as above set forth, the nipple I has been adjusted to The nipple valve 1 also prevents sudden excessive fluctuations of pressure in the gas main which cause flickering of lights sup plied from said mains and is used chiefly for this purpose.
