'UNI'FED STATES TIMOTHY KIELEY, OF NEW YORK, N. Y.

IMPROVEMENT IN STEAM-TRAPS.

Specification forming part of Letters Patent Nol90,7l9, dated May 15, 1877; application filed February 7, 1877.

To all whom it may conceml' Be 'it known that I, TIMOTHY KIELEY, of the city and county and State of New York, have invented a new and Improved Steam- Trap; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the annexed drawing, making part of this specification, in which Figure 1 is an elevation in perspective; and Fig. 2 is a vertical section, showing the whole internal construction.

This steam-trap consists of a reservoir, A, partitioned by a flexible diaphragm-plate, B, to the center of which there is connected a shaft, 0, the end of which is fitted with a lever, D, the upper end of which is connected to a shaft, E, passing out of the reservoir through a stuffing-box, as shown in Fig. 1; and also of a receiver, F, placed above the said reservoir, and connected to it by means of two pipes, G and H, the pipe H beginning in the top of the reservoir and terminating in the bottom of the receiver, as shown by Fig. 2.

To the top of said receiver F is applied a pipe, I, the end of which is fitted with adouble valve-chest, J J, a valve -stem, m, and two valves, K L, and two pipe-connections, P Q. Said valve-stem and valves are operated by means of a cam-lever, n, applied to the end of a shaft, 0, which passes out of the upper valve chamber through a stuffing-box, as shown by Fig. 1. To the end of this shaft 0, outside of the stuffing-box, there are appliedtwo levers, R u. Upon the end of the lever B a weight, V, is hung, and to the end of thelever, a link, a, is connected, uniting the valves with the diaphragm-plate by means of the rod T. To the side of the pipe H there is connected a pipe, w, to which is applied a pipe, X, fitted with receiving and delivering check-valve yz.

The trap, being constructed as above described, operates as follows: Let the pipe z be connected to the condensed-water side of the steam-heater, and the pipe 3 to the steamboiler, and let the pipe P be also connect-ed to the boiler, and the pipe Q to the sewer or waste-pipe, and let the trap be charged with water, as shown by Fig. 2 of the drawing.

The diaphragm-plate, owing to the column 'of water G, will be forced over to the left, as

shown in the drawing; but as soon asthe condensed water from the heater fills the re ceiver F, an equilibrium will be established on the two sides of the diaphragm-plate, which will then, by the aid of the counter balance, be forced over to the other side, and carry with it the lever D. This will actuate the shaft E and the rod T, which, moving around the shaft E as a center, will move the lever u on the shaft 0, and open the valve K and close the valve L through the cam n, by which the steam from the boiler will enter the top of the receiver, and force the water through the valve y back into the boiler, leaving the column of water G to press over the diaphragm-plate and close the steam-valve, as before. The condensed water will then begin to fill the receiver again, and so on continually, the valve L remaining open, while the steam-valve K is closed to allow the air to escape from the top of the receiver into the waste-pipe or sewer.

claim The combination of the receiver F, pipe G and pipe H, chamber A, interposed diaphragm B, valves K and L, and mechanism for connecting the diaphragm and valve, substantially as and for the purpose set forth.

Dated February 2, 1877.

TIMOTHY KIELEY.
