. My invention relates to im rovements in flush valves, and the object 0 my improvement is to supply a device of this character of a compact, simple and economical construction, and including both manual starting means and an automatically. controlled flushing rotor adaptable and adjustable for supplying a desired quantity of a flushing hollow 2.

liquid for any purpose desired.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Fig.1 is

a vertical transverse section ofwmy improved herein shown and described, nor to the various details thereof, as the same may be -modified or rearranged in various particulars without departing from the spirit and scope of my invention, one practical embodiment of which has been herein illustrated and described without attempting to show all of the various forms and modifications "in which my invention might be embodied.

My device is particularly appropriated for use in the flushing of water closet bowls and for which it is most suitably adapted.

The devicehas a hollow cylindrical body 1, preferably a metal casting having an upwardly directed integral valve-chamber 8 whose chamber hollow 9 is open at the top and supplied with a screw closure 10 having a. central depending socketed projection 13 to receive and serve as a top guide for a cylindrical stud 27 on the topof a fiat circular valve 26 in and of less diameter than said chamber.

The bottom of the chamber 8 has ports 6 and an apertured cross memher 7 traversed slidingly by a depending stem 28 fixed on the bottomof said valve 26 and having a terminal cage containing,

an antifriction ball 29 movable in the body chamber 5 below the hollow 2 of the latter chamber and at times downwardly into the The valve chamber 8 is ported laterally to receive one end of a supply conduit 12 in communication with a supply of water or o of t ther liquid under head. The lower part he rotor chamber 1 is formed with an integral delivery nipple 3 in communication with its interior 2.

he rotor chamber 1 contains a central rotatable shaft 16 from front to back, its rear end seated'in a bearing socket 24 in an outwardly projecting boss 23. A headed ended screw 25 is mounted in a threaded aperture in said boss 23 to bear at its flat end ad ustingly upon said shaft frictionally,

with more or less braking force according to its adjustment, to thus allow of the relative retardation of the rotation of the shaft.

- The front ofthe chamber or body'l is open but has an interiorly threaded seat 'atl 5 toseat a front circular closure 14 removably, said closure having an outwardly projecting central hollow boss 31 havingan fere of t

ntially spaced radial vanes 20 terminatclosely to the inner circumferential wall he chamber hollow 2. These vanes are connected a little to the rear of the middles of sand vanes by a flat annular web 17 whose peripheral edge is troughed around shallowl at 19 to seat said anti fiiction ball herein, and this peripheral edge has an inwardly curved recess 18 which makes it a locking cam for said valve stem 28 and the ball 29.

The numeral 36 denotes a mating clutch disk with teeth to mate with the teeth on the disk 37 at times, and the disk 36 is also rotatably mounted in the hollow of the boss 31 at its inner unthreaded end. The disk 36 is integral with the end of a short shaft 38 alined with said shaft 16 and carrying an enlarged cylindrical part 39 mounted both rotatably and slidably in the hollow sleeve 32 which latter is exteriorly threaded to be seated adjustingly in the threaded inner wall of said boss 31. An annular nut 33 on the outwardly projecting end of the sleeve 32 holds it in a desired adjustment longitudinally in the boss 31.

On the outer extremity of the shaft 38 is fastened a short starter handle 40 removably. A shortcoiled spring 42 is mounted around the shaft 38 within the hollow of the sleeve 32, having one end fastened thereto at 43 and its inner end fastened to said shaft, at 44. On the inner end of the sleeve 32 is an inwardly projectingcam34 of ramp shape, and a like but reversed cam35 on the outer face of the toothed disk 36 is located thereon to, at times, ride upon the cam 34 when the handle 40 is rocked in one direction, tensioning said spring 42, and the mating cams then operate in thrusting the clutch disk 36 to engage its teeth with the teeth of the clutch disk 37, so that the handle 40 in its further movement rocks the rotor with the shaft 16 to cause the cam edge of the annular web 17 to push upwardly the stem 28 and valve 26, this initial position of the parts being shown in Fig. 1. The valve 26 being thus opened, water or other liquid under head from the conduit 12 traverses the valve chamber 9 and the ports 6, impinging upon the vanes 20 of the rotor in succession while rotating the latter, the moving water then being delivered through the flushing nipple 3. The rotor makes but one rotation, as the ball and stem 29 and 28 drop into the cam depression 18 and lock the cam and the rotor against further rotation. A single flushing charge ofliquid is thus delivered by the device, the quantity being dependent upon the retardation of rotation of the rotor by the adjusted friction of .the screw 25- upon the rotor shaft 16.

The operator has need only to rock the handle 40 about a one quarter rotation to cause the action of the cam projections 34 and 35 to engage the clutch disks 36 and 37 and then cause sufficient initial rotation of the rotor cam 18 to lift the ball 29 and stem 28 up to ride upon the circular edge of the cam in the peripheral groove 19, the groove preventing sidewise displacements .of the ball. The operator releases the handle, allowing the tensioned spring 42 to react,

outlet ports, a valve chamber in communicationbetween said inlet port and a supply of liquid under head, a valve in said chamber to close said inlet port, an adjustable movable device in said casing coacting with said valve to intermittently cause the opening of the valve while movably adjustably controlling the passage of liquid from said inlet port through the casing to said outlet port, and resiliently controlled manuall operable starting means axially longitudinally shiftable and releasably engageable with said movable device, said movable device having a releasable locking engagement with said valve at each actuation of the movable device to restrict the device to a single action induced by said starting means. a

2. In a device of the character described, a casing having inlet and outlet ports, a rotor in said casing having vanes partitionallyldividing the interior of thecasing into circumferentially opening pockets, a valve chamber in communication between said inlet port and a-supply of liquid under head,

avalve in said valve chamber havinga stem extending through the casing reciprocatingly into its interior and having an antifriction ball mounted on its extremity, said rotor comprising a circular cam having a depression with like curvate shoulders to render the cam reversibly rotatable in its cam edge, its cam edge being troughed around to seat said ball therein, an adjustable contact member for frictionally retarding adjustably the rotatory speed of said I rotor.

3. In a .device of the character ,described, a casing having inlet and outlet ports, ,a valve chamber in communication between said inlet port and a supply of liquid under pressure, a valve in said valve chamber having a depending stem traversing the casing wall, a reversible vaned rotor in and fitting said casing whose vanes subdivide said casing and having a medial circular .cam provided with a synclinal depression, said valve stem having a terminal contact with the cam edgeto be interlocked with said depression at each rotation of the rotor with said valve closing the inlet port, and a manually operable resiliently controlled starting device including mating clutch members for longitudinal separation and for an initial rotatory impulse to be given thereby in starting rotation of the rotor to shift said valve stem out of the cam depression and upon its circular edge, said clutch members being resiliently controlled when the starting device is manually released to disconnect, permitting the rotor to rotate one revolution in passing liquid from said valve chamber through the casing to the outlet port by impact of the liquid with the rotor vanes in filling the pockets of the rotor in succession.

In testimony whereof I aflix my signature.

WILLIAM MOONEY.
