SPECIFICATION forming part of Letters Patent No. 759,461, dated May 10` 1904.

Application filed March 5, 1904. Serial No. 196,734. (No model.)

T0 all whom t may concern: Y

Be it known that l, ANDREW K. MONTGOM- nRY, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a `certain new and useful Improve ment in Steam-' l`raps, of which the following is a true and exact description, reference being had to the accompanying' drawings,which iorm a part thereof.

My invention relates to a novel construction of steam-trap, preferably used in combi nation with a steam-separator.

The object of my invention is to provide a device of this kind of simple and efficient operation in which a trap-separator is connected with the steanrconduit, and preferably with a separator-chamber constituting part of said conduit, by two ports, one normally open and provided with a valve held a short distance from itsseat by resilient means and the other ol contracted area and preferably constantly open. The trap-chamber is provided with a waste-pipe having a valve which normally closes it, and the chamber is also provided with a movable device actuated by the accumulation and discharge of water from the trap-cha1nber and connected with the valve of the waste-pipe, so as to open the same when the accumulated water reaches a determined amount. rl`heV opening of the wastepipe valve by releasing the pressure in the trap-chamber causes the valve operating on the port connecting the steam-pipe and trapchamber to close, and said valve will remain closedwuntil after the waste-pipe valve has closed and until the steam enteringV the trapchamber through the constantly-open restricted passage has restored a practical equilibrium of pressure between the steam-pipe and the trap-chamber.

In the drawings I have represented a steam separator and trap constructed in accordance with my invention in what l believe to be its most eiiicient form.

In said drawings, Figure l is a side ele vation of my device; Fig. 2, a vertical section on the lineQ 2 of Fig. l; Fig. 3, a crosssection on the line 3 3 of Fig. 1, and Fig. 4 a cross-section on the line L 4E of Fig. 2.

A represents the sepainting-chamber, having the steam-pipe entering it at A' and a steam-pipe leaving' it at A2, the chamber A thus constituting a part oi' the steam-conduit.

B represents the trap-chamber separated from the chamber A by the partition C, in which is formed the port and valve-seat (indicated at O') and which also separates the yoke, (indicated at O2.)

D is a steam-conduit oi restricted area connecting with the chambers A and B at t and as shown.

E is the valve, adapted to close the port C' vand having a valve-stem E' with nut E2 at top, between which and the yoke C2 is situated a light spring E, which normally holds the valve E a slight distance above its seat. r1`he upper part of the wall oi' the chamber B is constructed to form a bearing, as indicated at B', Jfor a rock-shai`t Fl, from which shaft a lever-arm F3 extends into the chamber B and connects, through a link F2, with a cross-bar or bail F', secured to the top oi' a bucket F, which is placed below the valve-seated port C', so as to receive any water which enters the chamber B through said port. The rockshaft F* has attached to one of its outer ends the lever-arm Fr, supporting a counterweight F and connected by a link F7 with a valve H', working in a valve-casing H, which is situated under a waste-pipe G, said waste-pipe, as shown, terminating in a siphon (ur' Gr, the arm (i of which extends into the bucket F, as shown in Fig. 2.

The steam entering the separator-chamber A deposits its condensed water therein, the water iinding its way through the port C' into the bucket F, and when a sufficient amount of water is collected in the bucket to overcome the counter-balance Fi the bucket moves down and the lever-arm F" moves up, opening, through the link F7, the valve H', whereupon the steam-pressure in the chamber B forces the water in the bucket F into the siphon-leg G and through the siphon out of the wastepipe. The escape of steam is prevented by the lowering of pressure in the chamber B, which causes the valve E to seat itself, and when the weight of water in the bucket F is sufficiently decreased the counterweight re- ICO stores the bucket to normal position and restores the valve H to its normally closed position. On the closing of the valve H the steam escaping from chamber A into chamber B through the pipe D gradually restores the pressure in chamber B, and When a practical equilibrium in the two chambers is secured the spring E3 opens the valve E, permitting any accumulated Water in the chamber A to iiow into the bucket F, the valve remaining open until the bucket is again depressed.

The construction described is given by me as that which I consider best adapted for the Work; but it is obviously capable of considerable change and modification without departure from the spirit of my invention.

Having now described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. In a steam-trap, a steam-conduit in combination With a chamber B, having a port connecting it with the conduit, a valve adapted to close said port, but normally held a short distance from its seat by resilient means, a second port of restricted area connecting the steam-conduit and chamber B, a Waste-pipe leading from chamber B, and provided With a normally closed valve, a movable device situated in chamber B, and actuated by the collection in and discharge of Water from said chamber, and means for opening the valve in the Waste-pipe actuated by said movable device When the Water collected in chamber B, reaches a determined amount.

2. In a steamtrap, a separating chamber forming part of a steam-conduit in combination With a chamber B, having a port connect- 'ing it With the separating-chamber, a valve leading from chamber B, and provided With a normally closed valve, a movable device situated in chamber B, and actuated by-the collection in and discharge of Water from said chamber, and means for opening the valve in the Waste-pipe actuated by said movable device When the Water collected in chamber B, reaches a determined amount.

3. In a steam-trap, asteam-conduit in combination with a chamber B, havingaport connecting it with the conduit, a valve adapted to close said port but normally held a short distance from its seat by resilient means, a second port of restricted area connecting the steam-conduit and chamber B, a bucket F, a lever and counterweight arranged to support bucket F, in chamber B, said bucket being so placed as to receive Water passing through the valved port into chamber B, a pipe G, connecting the bottom of bucket F, with a Waste-pipe G2, and a valve in pipe G2, connected and actuated by the movements of the lever supporting the bucket F.

4:. In a steam-trap, a separating chamber forming part of a steam-conduit in combination With a chamber B, having a port connecting it With the separating-chamber, a valve adapted to close said port but normally held a short distance from its seat by resilient means, a second port of restricted area connecting the steam-conduit and chamber B, a bucket F, a lever and counterweight arranged to support bucket F, in chamber B, said bucket being so placed as to receive Water passing through the valved port into chamber B, a pipe G, connecting the bottom of bucket F, With a Wastepipe G2, and avalve in pipe G2, connected and actuated by the movements of the lever supporting the bucket F.
