STEAM-TRAP.
ySPE(LIIIFICATION forming part of Letters Patent No. 425,108, dated April 8, 1890. Application iiled February 10, 1890. Serial No. 339,892. (No model.)
To all whom, it may concern.-
Be it known that I, JAMES O. RICHARDSON,
of Boston, in the county of Suffolk and State.
of Massachusetts, have invented certain new and useful Improvements in Steam-Traps, of which the following, taken in connection with the accompanying drawings, is a specification.
The object of my invention is to so improve the construction and arrangement of the parts of a steam-trap that it shall work very promptly upon a slight accumulation of water and be cheap and durable. This object I attain by the mechanism shown in the accompanying drawings, in which- Figure 1 is a vertical longitudinal section. Fig. 2 is a cross-vertical section taken on line Qc x of Fig. l. Fig. 3 is a vertical section through the valve-tube, showing the valve open.
III the drawings, A represents the water and float chamber case, and is provided at one end with a hand-hole device A', for convenience in cleaning and repairing, and an inlet-pipe A2.
B is a valve-tube attached by screw-threads or otherwise to the case A and by a unioncoupling D to the discharge or waste pipe C, which, if desired, Inay be connected to a water-tank. (Not shown.) The valve E swings on a horizontal pivot P and is connected to a rod II, said rod II having at its end afloat K. The extension II of the rod II serves as a lever against which the screw S may be operated when it is desired to force the valve E open, as indicated in dotted lines. The valve E is so fitted to the valve-tube B that when it stands in its normal position no flow of steam or water can take place in the valvetube B; but when inclined, as indicated by dotted lines, then steam or water, as the case may be, can freely iow around the edges of the valve through the grooves F F, made in the interior of the water-tube. -The valve E is pivoted upon the pin P, which passes through the walls of the valve-tube and centrally through the valve, as shown. IVhen the pin P is in place, the ends are entirely covered by the union-coupling D and held in place.
By making the case A and its inlet Aand valve-tube B in the manner shown, I have a clear working-passage from the inlet to the outlet, so that it is a very simple matter to clear out the trap when it becomes foul.
My valve operates as follows: If there is no water in the chamber of the trap, then the float K will lie on the bottom of the chamber and the valve E will remain in its normal position-that is, closed,-and no water can escape; but if water accumulates in the chamber then the Iioat K will rise up, as indicated in dotted lines, and the valve E will open (see Fig. 3) and allow a free passage of water over and under it through the grooves F F. As the water escapes the float will lower and close the Valve, and so hold it until the water again accumulates.
I claim-n 1. In a steam-trap, the combination of a chamber having an inlet and outlet passage aligned with each other and with the trend of the said chamber, with a valve adapted to close and open said outlet-passage and an operatingfloat attached to said valve, all op erating together substantially as and for the purpose set forth.
2. In a steametrap, the combination of a valve-tube having grooves F F with a valve E and float K, substantially as and for the purpose set forth.
3. In a steam-trap, the combination of the valve-tube B, the union-coupling D, the pivotpin P,held in place by the said union-coupling, and the valve E, substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 6th day of February, A. D. 1890.
JAMES O. RICHARDSON.
