BALL-COCK.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed May 2, 1908. Serial No. 430,448.

To all whom it may concern:

Be it known that I, WALTER J. FROST, a citizen of the United States, residing at Kenosha, in the county of Kenosha and State of Wisconsin, have invented certain new and useful Improvements in Ball- Cocks, of which the following is a specification.

This invention relates to improvements in ball cocks, and it has among its salient objects to provide a construction in which the parts are so organized that the valve member closes against its seat in the same direction in which the pressure of the in-' flowing water is exerted; to provide a construction in which the valve mechanism proper is of what is known as the Fuller type, i. 6. so organized that the valve plug is mounted on one end ofa stem, the other end of which is directly connected with a pitman wrist or other eccentrically located wrist, which in oscillating carries the valve to and from its seat positively; to provide in a mechanism of the character last above mentioned such a construction and arrangement that the operative mechanism is housed in an extremely simple and comparatively small casing, so disposed with reference to the valve seat that a direct connection is pro vided between the moving and moved members; to provide a construction which is ex tremely compact and so organized that it can be conveniently used either as a bottom inlet, as a side inlet or as an elevated standing-free inlet; to provide a construction in which by reason of the fact that the pressure of the incoming water aids in closing the valve, a small float but slightly lighter than the water may be used; to provide a construction which affords most convenient and reliable means for adjusting the several parts for different conditions; to provide a construction so organized as to be comparatively noiseless, and in general to provide a simple and improved device of the character referred to.

To the above ends the invention consists in the matters hereinafter described, and more particularly pointed out in the appended claims.

The invention will be readily understood from the following description, reference being had to the accompanying drawing, in which Figure 1 is a sectional view taken vertically and axially through the main body of the valve construction and through the tank in which the latter is located, parts of the tank and stem of the float being broken out to reduce the size of the figure; Fig. 2 is a vertical sectional view of the valve or ball cock mechanism taken at right angles to that shown in Fig. 1; Fig. 3 is a perspective view of the device detached and looking at the discharge side of the same. Fig. 4 is a horizontal sectional detail taken through the lower part of the tubular extension shown in Fig. 2 and looking upwardly.

In said drawing 1 designates a casing, which is interiorly cylindric, open at one end, closed at the other except for a central journal aperture 2, and provided at its lower side with a base flange 3 adapted to rest against the bottom or side wall of the tank, depending upon in which position the valve is placed. Through the lower side of the cylindric casing is formed an inlet aperture 4, interiorly threaded and receiving the correspondingly threaded upper end of a tubular extension 5. The interior of the tubular extension 5 is contracted near its upper end to provide an annular valve seat 6, and the lower end portion is threaded, as indicated at 7, to receive a clamping washer 8 threaded thereupon and cooperating with the flange 3 to hold the device in position. One end of the cylindric casing 1 is closed by a detachable spout member 9, which is preferably rabbeted, as indicated at 10, to fit partly within and partly against the end wall of the casing, and in itself so formed internally as to constitute a downwardly opening discharge spout. At each side the casing 1 l is provided with outstanding ears, as 11, and similarly the spout member is provided with outstanding cars 12 which register with the ears l1; clamping screws 13 being inserted loosely through the ears 12 and threaded into the ears 11.

Journaled to extend through the back or closed end wall of the main casing is a crank shaft 14, which accurately fits the journal aperture 2 and is provided at its inner end with a rigid crank arm 15 (preferably formed integrally with the crank shaft) and carrying a screw-stud or wrist 16 with which is connected the eye-portion 17 of a V valve stem 18. The valve stem projects downwardly into the tubular extension 5 and carries an elastic valve plug 19. The part of the stem which extends through the valve member is threaded, and nuts threadplug in suitably adjusted position relatively to the valve seat. Between the lower nut 21 and the valve body is interposed a guide washer 22, the main body of whichis of less diameter than the interior of the tubular extension and is provided with radial guide projections or star points 23 which engage the interior of the extension and keep the valve body substantially centered.

Upon the crankshaft 14' is fixed one member 24; of an adjusting ratchet; the inner face of said member being arranged to rest against a shoulder 25 formed upon the crank shaft substantially flush" with the outer end face of the casing so that the washer member serves to confine the shaft against endwise movement in one direction while the crank arm itself serves to prevent movement of the shaft in the opposite direction. The member 24 is shown as threaded upon the shaft but may be fixed thereon in any other suitable manner.

26 designates acooperating ratchet member which slips loosely upon the threaded external portion of the crank shaft; the meeting faces -.of the two

members

24 and 26 being provided with inte'rfitting teeth or ratchets, which, when the parts are held against each other, lock them rigidly together as regards rotative movement. Upon the end of the crank shaft is threaded a thumb-nut 27 which performs the function of so looking the ratchet members together in any desired angular relation to each other. The member 26 is provided with a socketarm 28 extending radially therefrom, with in which is fixed the stem 29 of a hollow ball or other suitable float 30.

It will be obvious that the angular position of the float stem and float relatively to the crank-arm may be adjusted at I will. These parts will, of course, be so adjusted that when the water level has risen to the desired height in the tank, carrying with it the float 80, the crank-arm will assume a position which holds the valve plug closed against its seat; such position being inclicated clearly in Fig. 1 of the drawing. As the water is let out of the tank for flushing purposes (the means for discharging the tank form no part of the present invention, and being not shown) the float descends, and in so doing forces downwardly the valve plug and opens the valve. Thereupon the water will flow in through the valve or ball cock, filling the interior of the chamber and discharging downwardly out through the spout member 9. The extremely small cylindric chamber which contains the opera- 1 tive mechanism, its location in direct alinement and immediate communication with the inlet port, and the short downturned outlet direct y communicating with this comparatively small valve chamber insure an almost noiseless operation of the device; there being little or no opportunity for gurgling with its incidental noise.

The device embodies the desirable ad- 'justability and positiveness of action of the Fuller type of valves, enabling the device to be adjusted to compensate for wear and deformation of the valve plug with. the greatest facility, and it is to be noted that the parts are so constructed as to be capable of manufacture at an extremely low cost.

That is to' say, the form of construction is; such that it may be readily cast or formed of drawn metal parts; the cylindric sides and circular end of the main casing are concentric with the' ournal aperture therethrough so that these parts may be most conveniently turned or dressed off; the receiving end of the discharge spout is bored concentric with the rabbet 10' at the periphcry of this member so that these parts may be conveniently machined, and the construction throughout is well designed to be manufactured at a minimum cost, and at the same time secure a most durable and effective construction.

No change whatever in the construction is necessary to adapt it for use as an inlet through the side wall of a flushing tank and where it is desired to use it as a standingfree elevated inlet, this is accomplished by simply mounting it upon the upper end of a pipe which extends through the bottom" wall of the flushing tank and rises to the desired height.
