APPARATUS FOR EJ'ECTING FLUID MATTER.

T 0 all whom it may concern:

Be it known that I, HUBERT BEDDOES, a citizen of the United States, and a resident of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Apparatus for Ejecting Fluid Matter, of which the following is a specification.

Heretofore it has been customary to eject sewage and other fluid matter from tanks by air acting expansively, z'. e. at each op eration, there is admitted to the tank that charge of air under pressure which acting expansively will give a resulting pressure suificient to lift the liquid to the point of discharge.

It is the object of the present invention to accomplish the desired object by the use of less air, or of air under less pressure, and this result I accomplish by mingling with the air admitted to the tank a quantity of steam or other hot vapor or gaseous fluid under pressure. The high temperature of the steam, Vapor or gas, thus mixed with the air acts to raise the temperature of the air and thus increases its expansion. The air thus mingled with the steam, vapor or gas, retards condensation and the effect produced is the result of the combined action of both the steam, vapor or gas, and air acting expansively on the liquid.

By the addition of a small quantity of steam suflicient expansion may be obtained to eject the contents of the tank from a charge of air, which, without the steam, would be Wholly inadequate. When there is available for the purpose exhaust steam or hot gases exhausted from a gas engine, which would otherwise be wasted, a great saving may be eifected by the use of the invention. My invention is not, however, limited to the use of exhaust steam, gases or vapors, but the steam, gas or vapor, used must have sufficient heat and pressure to raise the temperature of the air to a substantial extent.

The drawing shows a partly sectional side elevation of an apparatus embodying the invention.

a is any appliance to which the pressure is applied at intervals; as shown it is a forcing tank or receptacle which receives sewage through a supply pipe at, and from which the sewage is discharged through a discharge-pipe M.

d is a fluid pressure pipe which leads to Specification of Letters Patent.

the upper part of the receptacle a, as through the mixing chamber Z) opening into the top a of the receptacle.

(i is the pressure-main from which the pipe (Z leads, the communication between the pipe (Z and the main (Z being controlled by the valve mechanism 0.

0 is a pipe leading from an exhaust-pipe or any other source of supply, by which steam or other hot vapor or gaseous fluid above atmospheric pressure is supplied to the mixing chamber 7) and receptacle a. The pipe 0 is provioed with a hand valve 0 f is a small bell in the upper part of the appliance a from which an air-pipe f leads to the valve-mechanism 0.

7c is a valve in the pipe 0 which is controlled through an air-pipe 70 from the valvemechanism c. As shown this valve is opened by a small pressure-motor 70 operated by the pressure admitted through the pipe 76 and is closed by a spring 76 when the pressure in the pipe 70 is relieved.

When the sewage, or other liquid, rises in the tank a beyond the end of the bell f, air is forced through the pipe f to the valvemechanism, and puts that mechanism in operation to admit air under pressure to the pipes (Z and 70. A small quantity of steam, vapor or gas, is thus admitted to the chamber Z) and tank a with a charge of air. The air and steam, vapor or gas, thus admitted act expansively upon the surface of the liquid contained in the receptacle a and drive the liquid out through the discharge pipe (4 As the temperature of the air is raised by the steam, vapor or gas, its expansion is increased, and at the same time the mingling of the air with the steam, vapor, or gas, retards condensation, so that the expansive force is much greater than could be obtained by the action of steam or air alone; and the force required to discharge the contents of the receptacle (4 can be obtained with air at less pressure, when supplemented by a small volume of steam, than would otherwise be possible. hen exhaust steam, vapor or gas,-which would otherwise be wastedis used for the purpose, a substantial saving results in the operation of the apparatus.

The particular construction of the valvemechanism which controls the admission of the air and steam is not material to the illvention. Any form of mechanism may be employed which will operate to admit a change of air to the pipe 03 and simultaneously open a valve in the pipe 0 For the purpose of illustration I have shown the valve-mechanism fully described in Letters Patent No. 979,698, dated December 27th, 1910. By this mechanism, at each operation a main valve is momentarily opened to admit a charge of air fram the main (Z to the air pipe (Z, and at the same time a charge of air is admitted through branch pipes d (Z to the pipe 70. This acts on the motor k to open the valve is for an instant and admit the desired quantity of steam.

It is to be understood that where in the claims I speak of the pipe 0 as a steam pipe I mean to include such a pipe when used to supply any other hot vapor or gaseous fluid for the purpose described.

What I claim is as follows:

1. In apparatus of the character described, the combination of a tank to contain fluid matter having a discharge-pipe, an air-pressure-pipe and a steam-pipe leading to said tank, and valve-mechanism controlling said steam-pipe and air-pipe to control the admission of steam and air together to said tank.

2. In apparatus of the character described, the combination of a tank to contain fluid matter having a discharge-pipe, an air-pressure-pipe and a steam-pipe leading to said tank, and valve-mechanism controlling said steam-pipe and air-pipe to control the admission of steam and air together to said tank and controlled by the conditions in said tank.

3. In apparatus of the character described, the combination of a tank to contain fluid matter having a discharge-pipe, an airpressure-pipe and a steam-pipe leading to said tank, and valve-mechanism controlling said steam-pipe and air-pipe to control the 5. In apparatus of the character described,

the combination of a tank to contain fluid matter having a discharge-pipe, an air-pressure-pipe and a steam-pipe leading to said tank, valve-mechanism controlling steam-pipe and air-pipe to control the admission of steam and air together to said tank, an air-bell in said tank, and an airpipe leading from said air-bell to the valvemechanism and controlling its operation.

6. In apparatus of the character described,

the combination of a tank to contain fluid matter having a discharge-pipe, an air-pressure-pipe leading to said tank, a steam-pipe also leading to said tank, a valve-device in said steampipe, an air-pipe leading to said valve-device in the steam-pipe and controlling it, and valve-mechanism for controlling the admission of air to said air-pipe leading to the tank and to the air-pipe leading to the valve-device in the steam-pipe.

In testimony of Which invention, I hereunto set my hand.
