WATER COCK.

"bllmlluummmluuuuu THOS. BIRCH AND LEWIS BRADLEY, OF HARTFORD, CONNECTICUT.

WATER-CLOSET.

Specification of Letters Patent No. 22,543, dated January 11, 1859-.

T 0 all whom it may concern;

Be it known that we, THOMAS BIRCH and LEWIS BRADLEY, of Hartford, county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Devices to Regulate the Gradual Stop-Oft of ater-Cocks; and we do hereby declare that the same is described and represented in the following specification and drawings, and to enable others skilled in the art to make and use the same we will proceed to describe the construction and operation, referring to the drawings, in which the same letters indicate like parts in each of the figures.

The nature of our improvement consists in constructing an air vessel, or in the employment of an air vessel to produce a gradual stoppage of the flow of water as applied to water closets.

In the accompanying drawings Figure 1, shows a side view or a water closet arrangement with the improvement attached. Fig. 2 is a sectional view of the improvement.

A, is the metallic disk.

B, is a flange-ring, which is secured to the flange of the metallic disk.

C, is a metallic arm projection, made in a curvated form, so as to afford means of securing it, when desirable, and also to secure the cock E upon the end thereof.

F, is a valve disk, having a neck piece H, and chambered so as to allow of a free admission of air.

I, is a cap having openings (4 a to admit air, when the valve is open, and is fitted onto the neck of the valve disk.

G, is a cap having a screw plug which fits into the chamber of the valve disk F, and having a valve seat J.

K, is a valve stem, having a valve L, on the lower end and also having a spiral spring N, thereon between the valve L, and cap I. The valve-stem K has a hole made in the end thereof extending up just above the cap I, and is intersected by quite a small hole M, just above said cap. The spring N, is designed to press the valve L to its seat when the lever O is dropped, and thus prevents the air escaping back through the valve L.

P, is an opening in the spindle for the end of the lever Q, which opens and closes the cock E.

R, is an arm extending from the lifting spindle and is secured thereto by a set screw and having a hole in the end, through which the valve stem K, passes, having an adjustable nut on the upper end thereof, so as to regulate the height which the air valve shall be lifted. The elastic diaphragm D is secured between the metallic disk rim A, and the flange ring 13, by the outer edge, and the center between the underside of the valve disk F, and the cap G.

The water is conducted to one end of the cock E, by a pipe, and from the opposite end of the cock to the basin in the ordinary way. Now as a person takes hold of the knob S, and hits in the ordinary way, the projecting arm It, also lifts against the nut T, lifting also at the same time the diaphragm D, the valve L, lever Q, together till they are brought into the position shown in Fig. 1. The diaphragms D, F, being filled with air, the cock I being open so as to admit of a free [low of water into the basin U, and as the air gradually exhausts out of the chamber of the diaphragm through the small hole hi, it closes, carrying down the end of the lever Q, thus closing the cock E, in a greater or less time, by increasing or diminishing weights upon the diaphragm F or its spindle K. Thus we are enabled to produce a simple, durable and efficient mode of gradually closing oil the flow of water, after it has been started. These features also constitute the principal and decided advantages derived over other devices now in use.

Ive are aware that various devices have been used for the purpose herein described, by the use of water and air valves of different construction. But

What We claim and desire to secure by Letters Patent is- The arrangement of the metallic rim B arm C, disk F, cap G, lever Q in the manner as and for the purpose described.
