T0 at whom, it may concern.-

Be it known that we, DANIEL H. STREEPER and JOHN W. OELENSCHLAGER, of Norristown, county of Montgomery, and State of Pennsylvania, have invented an Improvement in Steam-Separators and Automatic Shut-Oifs, of which the following is a specification.

Our invention has reference to steam-separator and automatic shut-off for steamengines and it consists of certain improvements which are fullyset forth in the following specification and shown in the accompanying drawings, which form a part thereof.

In the operation of high-speed engines great danger frequently results from flooding the engine with water brought in with the steam, said water being causedbyunobserved carelessness in flooding or priming in the steam-boilers.

The object of our invention is to provide automatic means which shall operate to automatically shut off the water and steam from the engine should any excessive quantity of water be carried into the steam-supply pipe leading to the engine. Our object also comprehends the separation of the water from the steam which passes to the engine, whereby the apparatus may operate automatically as a shut-off against the passage of excessive quantities of water and as a separator for eliminating the water from the steam before it reaches the engine.

In carrying out our invention we provide the steam-supply pipe with a valve mechanism arranged to be automatically closed by the presence of incoming water due to the boilers priming or flooding, so as to shut off the supply-pipe between the boiler and engine, and said devices maybe used separately or in combination with a steam-separator. Our improvements also include means for automatically discharging the incoming water in an intermittent manner until the same is eliminated.

Our invention also comprehends details of construction which, together with the features above specified, will be better understood byreference to the drawings ,inwhich Figure 1 is an elevation showing the arrangement of our improved steam-separator pipe to the engine.

and automatic shut-off in the steam-supply Fig. 2 is a sectional elevation of our improved steam-separator and antomatic shut-off. Fig. 3 is a cross-section of same on line 3 3, and Fig. 4 is a modification of our improved device.

A is the engine, and B is the steam-supply pipe connecting the engine with the outlet side of the separator and shut-off D.

O is the throttle controlling the engine, and E is the pipe leading from the boiler to the inlet of our improved separator and automatic shut oif. The interior chamber F of the separator is provided adjacent to themlet with a valve-chamber I, in which a balan'ced valve J reciprocates to control the passage of steam and water from the inlet G into the interior of the body of the separator and automatic shut-off. The valve J is hung from an arm K, secured to a rock-shaft K, which extends transversely from the separator-body through a stuffing-box and is secured to the counter-shaftK ,havi11g an adj ustable weight K In this manner the valve may be so counterweighted as to normally remain open under the flow of steam. An adjustable stopL in the cap of the separatorbody limits the upward movement of the valve. Suspended to the under part of the valve is a bucket M, having one or more perforations N at the bottom, so that any water which enters this bucket may gradually run out of the bottom thereof in the lower portion of the chamber F and thence by a pipe R discharging through a steam-trap S of any ordinary construction. The steam which passes under the upper portion of the valve into the space F cannot pass into the'outlet because of the transverse diaphragmP and is caused to flow downward on each side of the valve-chamber into the lower chamber F of the body and there commingle with the steam passing from the inlet below the lower portionof the valve J. The steam then passes upward around the inclined baflieplates 0, giving up any water which it might contain, and thence passes by the outlet H into the steam-pipe leading to the engine.

It is immaterial to our invention what the particular construction of the separator porlOt tion may have, as it may be modified in various ways, so long as it is adapted to separate the water from the steam, as will be understood in such class of device. So long as steam without any appreciable quantity of water asses from the boiler to the engine the va ve J remains elevated and the steamseparator acts in the ordinary manner. If, however, from priming or flooding of the boilers an excess of water should suddenly rush through the steam-pipe E into the inlet G, it will on account of its heavyweight fall directly into the bucket M, which will overload the valve and cause it to close, thereby completely shutting off the steam and water from the pipe B, leading to the engine, and by slowing down of the engine the engineer will be notified that something is wrong and have an opportunity to close the throttle C before any damage could result. As the water runs out of the bucket N the weight of the water decreases until finally the valve J will open slightly and a further supply of water will pass into the bucket, and this operation might be repeated a number of times; but at no time could the water be carried through in volume to the engine. As the water collects in the bottom of the chamber F it passes by pipe R into the steam-trap S, thereby discharging without loss of steam.

It will be observed that in the operation of this device the weight of the water is that which controls the automatic valve to close it, and this may be accomplished by other means than the bucket-such, for example, as a float M in a tank M having a drainageoutlet N, as shown in Fig. 4. In this case the automatic valve opens downwardly to permit the passage of the steam and upwardly for the closing of the valve under the buoyancy of the float M in the water which may collect in the tank 1W from any inrush of water from the inlet G. In this case the volume of the water operates through the buoyancy of the float to close the valve, whereas in the construction of Fig. 2 the volume of the water by its dead-weight operates to close the valve. In both, however, the mass of water is that which directs the closing of the valve.

While the constructions shown are excellently adapted for the purpose of our invention, we do not limit ourselves to the minor details, as they may be modified in various Ways without departing from the principles of the invention.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

2. In an automatic shut-oii for controlling the supply of steam and water, the combination of a steam-passage, a normally open valve to control said passage, and means operated by the mass of water passing through the inlet side of the valve for automatically closing the valve when said water is in excess consisting of a bucket connected to and arranged below the valve to receive the water passing through the valve.

3.
