STEAM-TRAP.
SPECIFICATION forming part of Letters Patent No. 467,634, dated January 26, 1892.
Application filed December 5, 1890. Serial No. 373,639. (No model.)
drawings representing like parts.
This invention has for its object to improve the construction of steam-traps. In accordance with this invention a thermostatic valve is contained in a shell or case of suitable length to receive it, said thermostatic valve consistingof a longitudinally-expansible tube, preferably corrugated and adapted to be filled or not, as desired,'with expansible liquid. A chambered block, which may be a casting, is secured to said shell or case, which has formed in it, and projecting centrally into the chamber thereof, a nipple having a passage through it communicating with the interior of the shell or case. On the underside of the chambered block opposite the nipple a valve-seat is formed for the thermostatic valve, and said valve is provided with a suitable guide or leg which enters the passage through the nipple. A strainer, preferably conical in shape, may be secured to the nipple within the chambered block. That portion of the chambered block around the nipple serves as a sedimentreceiver for scale and the like, and to this part of the block a blow-0E cock is secured.
The drawing shows in vertical section a steam-trap embodying this invention: The shell or case a is made of any suitable length, and for this purpose I preferably utilize a piece of pi A thermostatic valve is placed within the shell or case a, it consisting, as herein shown, of a longitudinally-expansible tube a, preferably corrugated, andadapted to be filled or not, as desired, with expansible liquid, and having at one end a valve a provided with a guide or leg a and having at its opposite end a screw-threaded portion or. The thermostatic valve is adj ustably held in position at one end by its screw-threaded portion a entering a screw-threaded plate or cap I), which is secured to one end of the shell or case a. The plate or cap I) has several ports, as I), through it. Achambered block 0 is secured to the opposite end of the shell or case a, it having formed within it and projecting centrally into it anipple c,hav1ng a passage through it. The under side of the chambered block 0 opposite the nipple c is formed to serve as a seat. for the valve a and the guide or leg a of said valve enters the passage through the nipple c'. The nipple c is directly opposite the entrance to the steamtrap, and it has secured to it a conical strainer 0 The annular chamber surrounding the nipple c is quite deep, as shown, and serves as a sediment chamber or receiver for scale, dirt, and the like. At the lower end of this annular sediment-chamber a blow-off cock d is secured. The steam entering the chamber 0 may pass through the nipple c and, if the valve is open, into the shell or case a; and out through the ports I). As the tube a expands, the valve a closes against its seat and the progress of the steam is checked. As the water of condensation gradually rises in the chamber 0, it flows over the top of the nipple c and passes into the shell or case a on a very slight opening of the valve. By opening theblow-oif cock d any sediment or water may be immediately removed. By making the tube a corrugated it may be slightly compressed if overheated.
I claim In a steam-trap, the combination of the following instrumentalities, viz: the shell or case a, a thermostatic valve contained therein,
.composed of a longitudinally-expansible tube preferably corrugated and having at one end the valve 71 and at the opposite end the portion a by which said thermostatic valve is adjustably supported in the shell or case a, the chambered-block c at the entrance to said trap, the nipple 0', having a passage through it and projecting into the chamber of said block to thereby form an annular sedimentchamber, a blow-oft cock at the lower end of said sediment chamber, and a valve-seat formed on the under side of said chambered block 0 opposite said nipple c to serve as a seat for the valve a substantially as described.
In testiinony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
