IMPROVEMENT m sToP-vALvE's.
Specification forming part of Letters Patent No. 1 81,684, dated August 29, 1876; application filed July 22, 1876.
To all whom it may concern:
Be it known that I, JAMES D. KEEGAN, of
the city, county, and State of New York, have invented a new and Improved Stop-Valve for Water- Works, of which the following is a specifloat-ion:
Figure 1 is a vertical section on line a; w in Fig. 2. Fig. 2 is a section on line y 3 in Fig. 1.
Similar letters of reference indicate corre-' sponding parts.
The invention consists in rendering the stopvalve of water-works more easy and convenient in operation by providing the case and valve with a flange and balls, arranged as hereinafter described.
A is a casing of a valve, in the bottom of which the annular groove a is formed. Bis a valve, having the staves 1) connecting the upper and lower portions of the valve, the whole being fitted closely to the casing A, so that the staves b will stop the passage through the valve when turned so as to cover the openings in the casing. In the bottom of the valve B an annular groove, 0, is formed, which corresponds with the groove a in'the bottom of the casing. When balls are used to support the valve, the grooves a and c are nearly semi- I circular in section but when rollers are used the grooves are made to conform to the rollers. 61 d are balls placed in the groove a to support the valve B. A gudgeon, 6, projects from the center of the lower end of the valve B, and has a suitable bearing in the casing A. At f there is a flange which rests in a recess in the casing and assists in supportingthe valve. The upper portion of the valve B is bell-shaped, and terminates in a cylindrical stem, g, which is squared at the outer end to receive a wrench or lever. O is a hemispherical cover provided with a flange, h, which is bolted to a flange, i,
on the casing A. D is a stuffing-box formed on the cover 0 which surrounds the stem 9. If a valve is so large as to require gearing to move it, the gearing may be placed at the bottom of the casing, so that a portion of the weight of the valve may be supported by it. In very heavy valves the flange f may beprovided with teeth on its periphery, and a pinion may be placed in the casing on a suitable shaft, whichprojects through a stuffing-box in the casing, so that it may be turned with a wrench 0r lever.
Having thus described my invention, I claim as newand desire to secure by Letters Pat-- ent The combination of the casing A, valve B, flange f, and balls 01, as shown and described.
