STEAM TRAP.

SPECIFICATION forming part Application led June 17,

To all whom it may concern:

Be it known that LEMANUEL 1-11PrARn,a ciiizen of the United States, residing atYoungstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Steam-Traps;l and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention` relates to steam-traps; and it consists, primarily, of the novel and peculiar construction and arrangement of an oscillating receiver whereby the water-inlet valve is operated by the The invention further consists of the general arrangement and combination of the several parts of the device as a Whole, as will he hereinafter more fully described, and particularly'set forth in the claims.

The general object of the invention is toproduce a steam-trap wherein the water is caused to flow from the shell or casing of the trap to the boiler -without the intervention of the usual valves.

Anotherobject of the invention is to provide means for delivering steam into the oscillating receiver to force the Water out into the shell, from whence it is forced through a suitable connection into the boiler, and also to provide means for the escape of the steam from said receiver after the water has been forced therefrom. A

Other objects of the'invention will become apparent upon further description thereof.

ln the accompanying drawings, Figure 1 is a side elevation of my improved steam-trap; Fig. 2, a front elevation of the same; Fig. 3, an interior view of the device, one-half of the shell or casing being removed; Fig. 4, a vertical longitudinal section on line 4 e of Fig.

1, some of the parts being in full lines; Fig. 5, a transverse section of the valve-casing, showing the valve in full lines; Fig. 6, a top plan view of the three-Way or union coupling and connections disconnected from the oscillating receiver and removed from the shell or casing; Fig?, a detail of the flap-valve and casing; S, a horizontal section through thc union-coupling, and Fig. 9 a vertical section through the oscillating receiver. y

Referring to the several views, the numeral riso and fall of said receiver. r

lof said valve-casing it, and the upper end vcover the circular row 1 indicates a suitable steam and water tight shell or casing composed of two parts 2 and 3, each part being formed at its edge with an outwardly-extending iiange 4, by means of which the said parts are irmly bolted together, as shown. At the lower front edge the part 2 is formed with an extension 5, having afluted outer surface,v and the part 3 with a similar extension 6, but having a smooth outer surface. When the two parts are bolted together, these extensions form a chamber 7, in which is located a rockable union connection 8, as will be hereinafter more fully described. The side wallY of the provided' with: varianged opening 9, and the side wall of the extension 6 is provided with a similar opening 10, .but of less diameter than the opening 9. These iianged openings serve as bearings for the rockable union connection, which is provided with three inter nally-screw-threaded openings 11, 12, and 13, respectively. ln the opening 11 is screwed a short tubular arm 14, which forms one of the journals of the union-coupling,the same beingY journaled in 'the bearing 9, and in the opening 13 is screwed an arm 15, which forms the other journal of the union-coupling, beingjournaled in the bearing 10. Suitable studing-boxes are provided for the journals, and incasing caps 16 and 17, bolted to the outer sides of the extensions, may be employed to protect the parts.

The numeral 18 indicates an oscillating receiver, preferably made of aluminium,having a projecting neck 19, into which is screwed one end of a valve-casing 20, vthe other end being screwed into the opening 12 of the union connection.l The valve-casing at one side is provided with a suitable check-valve 2l, which in the present instance consists of the iap or swing style. The oscillating receiver is provided with a central tube 22, (shown in Fig. 9 and by dotted lines in Fig. 3,) passing entirely through of the tube is provided with a collarA or nut 23, having a circular row of' perforations. f Movably fitted in said tube is a valve-rod 24, provided `with a valvehead 25, the latter being of sufficient diameter to of perforations. The arm 15 is provided with a centralbore, which is connected to a hollow `extension 2o,r

extension 5 is IOC ' actuated valve-rod Aby dotted lines in Fig.4 3.

To the outerpend of the a'rm 15 is securedun arm 30, on which is adjustably secured a eonnterbalancingweights31, ,bymeans of which the oscillating receiver is returned to normal position. (shown by dotted lines in Fig. 3) after each discharge of the Water from I said receiver.

vwhichthe iiow of water 'receiver to fall, and just before 'To the outer end of the tubular arm let there is connected by a suitable coupling one end of a pipe 32, which leads to a proper water-tank. (Notshown.) Thispipeisprevided with a suitable check-valve 33, by means of to the oscillating receiver may be automatically cut off. The:v casing 1 is provided at one side with a-.wateroutlet 34, to which may be connected the pipe leading to the boiler to be fed, and at the top with an inlet 35 for the introduction of steam, which ma'y be taken from the steamdome ofthe boiler.

In operation -the fiow of the water the pipe 32 exerts a force sufficient the check-valve 33 and permit' the water to enter the oscillating receiver, the pressure of steam A in ther-casing serving to maintain the valve 2l in closed position during the filling operation. When the receiver is lled, the counterbalance is overcome, allowingthe reaching the limit of its movement the end of the valverod 24 comes in contact with the bottom of the casing and is forced upward to uncover the circular row of perforations, so that the steam may enter the receiver. The steam entering the receiver overcomes the pres- `sure of the inflowing water and causes the valve`33 to close, thus shutting oit the supply of Water. At the instant the flow of water is stopped the Waterin the receiver exerts a pressure against the inner face of the valve 2l, and this pressure, reinforced through to open by the pressure of the steam entering the receiver, i's sufficient to overcome the pressure of the steam in the casing against the outer face of the valve 2l and cause it to open to permit the water in the receiver to be dis- A chargedainto the casingjromgvhence it flows unobstructed into the boiler. As soon as the receiver is emptied of its contents it is caused to rise by the-counterbalance, and the valvehead coming intecontact with the top of the casing it is pushed down and the flow of steam into the receiver is cut oil, the steam and air escaping through the vent-pipe 29 out into the chamber' of the cap 17 and thence into the open air through an outlet 3o in said cap when used. ,lyllben the receiver has ses,

reached its normal position, the pressure of the water on the valve 33 opens it, and the operation is repeated.

Various modifications and changes maybe made in the structure of my device without changing the principle or sacrificing the spirit of the invention. i

Having thus fully described my invention, what I claim' as new, and desire to secure by Letters Patent, is- 1 l.
