THOMAS FOULDS, OF TREVERTON, PENNSYLVANIA.

EXHAUST-STEAM RECEIVER.

SPECIFICATION forming part of Letters Patent No. 432,797, dated July 22, 1890.

Application filed March 22, 1890. Serial No. 344,992. (No model.)

T 0 allwhom it may concern.-

Be it known that I, THOMAS FOULDS, a citizen of the United States, residing at Treverton, in the county of Ncrthumberland and Statoof Pennsylvania, have invented certain new and useful Improvements in Exhaust- Steam Receivers; and I do hereby declare that the following is a full, clear, and exact description of the same, referencebeing had to the annexed drawing, making a part of this specification, and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements in devices for utilizing the exhaust-steam from the cylinder of a steam-engine.

It has for its object, among others, to relieve the piston on the exhaust side in the steam-cylinder and to reduce the impact on the water passing through the receiving-pipe to the pump.

Otherobjects and advantages of the inven tion will hereinafter appear, and the novel features thereof will be specifically defined by the appended claim. 1 i

The invention in the present instance resides in the peculiar combinations, and the construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in thedrawing, and particularly poin ted out in the claim.

The invention is clearly illustrated in the accompanying drawing, which, with the letters of reference marked thereon, forms a part of this specification, and in which is shown a side elevation with parts in section illustrating my invention.

Referring now to the details of the drawing by letter, A designates an ordinary steamcylinder; B, the pistorrrod; C, the steamchest; D, the slide-valve rod; E, the steampipe leading to the steam-chest, and F the exhaust-pipe therefrom. All of these parts are of ordinary construction and operate in the usual manner.

G is the steam -receiver for the exhauststeam, which is admitted thereto through the pipe F.

H is a coupling, to one end of which is con nected the pipe I, which is designed to be connected to the receiving-pipe leading to the well.

J is a pipe connected with the other end of this coupling, and designed tobe connected with the receiving-pipe of the pump.

The exhaust-steam receiver G is connected with the coupling by means of the pipe K, in which is located a stop-cock L in a branch, as shown, and exhausting into the air.

M is a stop-cock in the said connection near the connecting pipe or coupling. A nozzle N extends into the coupling with its discharge end turned upward, as shown.

In practice the exhaust-steam from the cylinder is first received through the exhaustpipe into the receiver Gfirst, to relieve the piston on the exhaust side in the steam-cyL inder, and, secondly, to reduce the impact on the water passing through the receiving-pipe to the pump.

I convert the receiving-pipe of the pump into a condenser, and a partial vacuum will be formed in the exhaust-pipe and the exhaust side in the steam-cylinder. To get a perfect working of the engine the exhauststeam must first escape into the receiver. The piston of the engine is thus relieved of its back-pressure and a portion of the impact removed from the water when the exhaust steam comes into contact with the current of water that is passing through the receivingpipe. The current of water being assisted rather than disturbed a more perfect working of the pump will be the result.

It is deemed important that the pipes F and K enter and discharge from the chamber G in substantially the same line, but with the pipe K on a higher lever, as shown, whereby the exhaust steam more readily passes from the pipe F to the pipe K.

What I claim as new is The combination, with the steam-cylinder and steam-chest, of the steam-pipe to the steam-chest, the exhaust-pipe F therefrom, the receiver G, receiving the exhaust-steam from the pipe F, the pipe K from the receiver opposite to and in the same line with but on a higher level than the pipe F, the cooks L and M in said pipe, the coupling H on the end of the pipe K and having nozzle within the same, and the pipes I and J, connected to said coupling upon opposite sides of the nozzle, substantially as specified.

In testimony that I claim the aboveI have hereunto subscribed my name in the presence of two witnesses.

THOMAS FOULDS.
