Combined Check and Throttle Valves.

f n Q UNITED STATEs PATENT QEEIcEo ANDREW G. SMITH AND PLATT S. OSBORN, OF OIL CITY, PENNSYLVANIA.
IMPROVEMENT IN COMBINED CHECK AND THR-OTTLEVALVES.l
Specification forming part of Letters Patent No. 157,941, dated December 22, 1874; application led January'27, 1873.
To all whom tt may concern: l
Be it known that we, ANDREW C. SMITH and PLATT S. OSBORN, both of Oil City, in the county of Venan go and State of Pennsylvania, have invented certain new and useful Improvements in Valves; and we 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
Our invention relates to improvements in combined check and throttle valves.
In the drawings, Figure l represents a horizontal transverse section, and Fig. 2 a plan view, of the valve complete.
Our invention consists in certain combinations and arrangements of devices and appliances, as hereinafter set forth and claimed,
wherein- A represents the chamber, containing both the check and globe valves. B is the stem of the check-valve C, which valve operates to open and close the opening E. D is a continuous partition, which forms the seats for the valves, traversing longitudinally the entire length of the chamber A, and provided with the central partition F, which separates the two valves. Gr is the stem of the globe-valve E, which valve operates to open and close the opening J in partition D. K is the supplypipe, which brings water into chamber A. L is the exit-pipe, which conducts the water off from chamber A to the boiler or other place. The arrows indicate the direction taken by the water in its passage through the valve.
The operation is as follows: The valves C and H are in the positions shown in Fig. 1. The action of the pump draws the water through pipe K into chamber A under valve C, the force of the water raising the valve. It then passes up through opening E, and down through opening J, and from thence through pipe L to the boiler. When the water ceases to act against the valve C, it returns to its place on the valve-seat by gravitation.
When it is desired to repair the check-valve, the globe or throttle valve is forced up against the valve-seat J, thus cutting oi' all communication between the chamber A and the exitpipe L. The check-valve may then be removed and repaired.
We are aware that valves have before been constructed with two independent valvesa check and a throttle valve; but the construe` tion of the chamber containing them and their operation are somewhat different from ours.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
The valve herein described, consisting of the globe-valve G H, check-valve B G, and continuous partition D, traversing longitudinally the entire chamber A, and provided with the central partition F and the openings E J, constructed, arranged, and adapted to operate substantially as and for the purposes set forth.
