SPECIFICATION forming part of Letters Patent No. 767,475, dated August 16, 1904.

Application filed March 4, 1904:.

To all whmn, it Duty concern:

Be it known that LTHOMAS F. FITZ SIMMONS, of the borough of Brooklyn, county of Kings, city of New York, State of New York, have invented a new and useful Duplex Gas-Receptacle, which is fully set forth in the following specification.

My invention relates to gas-receptacles for use in heat and power generating stations. In these plants are generated two kinds of ases. One, producer-gas,is comparatively thin, not having as much hydrogen as water-gas, the other kind. For commercial use the thin producer-gas has to be enriched by certain proportions of the Watergas. Exactly what proportion shall be used in any specific case depends upon the quality of the respective gases and upon the particular service required; but forgiven conditions the proportions must be definitely fixed and uniformly maintained to secure the highest efliciency. In practice this has required two separate gas-receptacles with separate inlets and outlets, complicated meters and adjustments, and continued Watchfulness on the part of several attendants in order to preserve the uniformity of the proportions passing into the service-mains.

My invention consists of a duplex tank having the features. hereinafter pointed out and claimed.

By means of my improved construction the service is facilitated in many respects, some of which will be pointed out.

The invention will best be understood by reference to the accompanying drawing, which is a perspective view illustrating one embodiment.

A represents the usual Water-tank, having four upright standards (J, secured by truss-braces D. Within this water-tank A are placed the two semicylindrical receptacles G and H, closed at the top and sides and open at the bottom and matched so as to fit together and Within the bore of the water-tank.

I represents brackets located on the top of the receptacles G and H and carrying rollers that bear against the upright standards C. At each end of the straight edge upon the top Serial No. 196.55% No model.)

of each gas-tank the roller bears against the side of its adjacent standard, whereas the roller located at the middle of the curved edge (forming with the other two rollers on its tank a triangle) bears against the inner face of its adjacent standard, so that the tank is guided evenly in its vertical travel without danger of binding or tilting.

BI 31 represent pipes, shown in dotted lines and leading, respectiveh from the interior of the receptacles G and H. The lower ends of these pipes are brought into a parallel position and lead into a proportional meter, which is indicated conventionally at 0. Each of these pipes may be divided by a longitudinal partition, so as to provide two separate passageways, one of which is an inlet M from the generator, and the other passage-way in the same pipe is the outlet to the supplyniains, and all the passage-ways are controlled by suitable valves, stop-cocks, and the like. The proportional meter 0, by means of aproportional valve (not shown) permits a nice adjustment of the amount of gas passing from each of the two receptacles G and H, so as to secure a proper proportional mixture of the two gases.

Two .semicylindrical receptacles, having each a capacity of ten thousand cubic feet, will suffice for a plant generating twenty million cubic feet per day, a not unusual amount. This amount of the two gases can be passed through the proportional meter 0 in almost absolutely exact proportions, which can be controlled at will. Owing to my present construction, one single water-tank A may be employed instead of two, which economizes space and material in installing the plant and permits the use of a single water-supply and a single attendant. Again,the two pipes M 1V1 can be arranged in juxtaposition and lead to the proportional meter, and, furthermore, the relative heights of the two receptacles can be observed at a glance, so that the attendant may note the rate at which the two tanks are discharging. Thus my construction serves as a check upon the indications of the meter.

I do not limit myself to the precise construction and arrangements above set forth. For instance, instead of making the two tanks each Correction in Letters Patnt No. 767,475.

an exact semicylinder one may be made larger than the other in various forms, the idea being to combine the two, so as to produce a complete cylinder that will operate within a single water-tank.

In practice I prefer to employ an automatic check-valve to prevent the tanks from being entirely emptied. The drawing shows a simple arrangement comprising a depending rod R, secured at the upper part of each tank at any convenient position and so arranged that its lower end will enter the outlet-pipe M. A disk S is secured upon each rod at a predetermined point, so that when the predetermined amount of gas has been withdrawn from the tank the disk will come in contact with the upper end of the pipe M and cut 05 the discharge. The disk S will be yieldingly mounted, as shown. By means of this automatic valve I prevent the escape of all the contents of the tank, so that the action of the engine or the exhaust cannot produce a vacuum within the tank and cause the latter to collapse.

Having thus described my invention, I claim 1. In a duplex gasometer, the combination with a cylindrical water-tank of two semicylindrical gas tanks moving independently therein, substantially as described.

2. A duplex gasometer consisting of the combination of a single water-tank, two separate semicylindrical gas-tanks operating independently therein, and suitable inlet and outlet pipes from each of the latter connecting with a single proportional meter.

3. A duplex gasometer consisting of the combination of a single 'atertank, four vertical standards rising therefrom, two semicylindrical gas-tanks operating therein, a roller carried at each end of the straight edge at the top of each of said gas-tanks and bearing against the side of its adjacent standard, and a roller upon the middle of the curved edge at the top of each tank and bearing against the inner face of its adjacent standard.

4:. A gasometer consisting of the combination with a single water-tank of a plurality of separate gas-tanks fitting together and fitting snugly within said water-tank and moving independently therein.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
