However the whole casing may if the socket I5 in the aforesaid hub I4 and extends 50 desired be formed of one integral casting or made vertically upward therefrom through the center up in any other suitable form.

the necessary vertical play of the valve while maintaining it in proper alignment with its seat. A pair (more or less) of latches 40 are hinged at their upper ends 4l in slots or notches 42 in said valve base 3l and hanging free of their own weight are balanced to swing inward toward the stem 36 at their lower ends whereby the hooks 43 as the valve is pushed down will slip over and engage the shoulder 44 below said enlarged upper end 38 of the stem and will thus hold the valve 29 in opened position (Figure 3). A carrier member or release block 45 is provided and same has an axially extended bore 46 adapted to clear and freely receive the stern 36 on which this member is mounted. The said stem has square or worm threads 41 throughout all of its length except for clear and reduced upper and lower end portions 48 and 49. Said bore 46 also clears this threaded length of the stem as shown. Wings or blades 50 are hinged at 5! in slots 52 cut at diametrically opposite points through the walls of the carrier member 45 and the outer ends 50a of these wings are twisted or inclined relative to the axis of the member whereby they serve or act as propeller blades in a manner to be described. The opposite ends of the wings have small short fingers or teeth 53.

In the normal position of the parts the carrier member 45 rests at the lower end of the stem 36 against a rubber bumper washer 54 and the wings 5U of their own weight hang down almost at against the sides of the member as shown in Figure 1. Now as the valve 29 is pushed open and locked by the latches 40 and water rushes through the casing as set forth above the force of the water will first raise or swing the wings 50 upward and outward and impinging against the twisted ends 50a thereof will impart a rotating motion to the carrier member 45 and will at the same time urge the same upward on the In this substantially horizontal position of the wings 50 the ngers 53 are swung inward and will then engage the threads 41 on the stem 36. These threads are so cut that the rotary movement thus imparted to the member 45 will cause it to screw up the stem 36 until it reaches the upper extremity of the threaded portion thereof. In this position the tapered end 55 of the carrier member strikes the lower ends of the latches 40 and forcing the same apart releases the hooks 43 from the shoulder 44 and allows the valve to close under pressure of the water in the casing. At the same time the upward flow of water being shut ofi the wings 50 fall back to their downward position releasing the fingers 53 from the threads 41 at the clear upper end 48 of the stem and the carrier 45 falls back of its own weight to its starting position.

During the time the valve 29 is open water rushes into the bowl C and flushes it thoroughly and at the same time a part of the water passes up through the opening 22 into the chamber 2| and as the valve again closes this water runs slowly out of the chamber and out through the outlet i6 into the bowl to form the necessary after fill or water seal. To prevent air from being trapped in the chamber 2| as it llsa small tube 56 is extended from the outlet I6 up to the top of the chamber as shown. From the foregoing it will be apparent that a push on the knob 21 sets the parts in operation so that a quantity of water runs into the bowl sufficient to completely flush the same after which the water is automatically shut off and the water seal provided.

The operation is simple and positive and a minimum of working parts and valves are used thus increasing the useful life of the device. An important feature is the compactness of the device and it will be evident that the casing may be very small since very little storage or tank space is required. The casing also lends itself to any ornamental finishing or formation and may even be concealed in the wall entirely hidden.

While I have herein set forth a certain preferred embodiment of my invention it is understood that I may vary from the same in minor structural details so as best to construct a practical device for the purposes intended, not departing from the spirit of the invention and within the scope of the appended claims.

I claim:

1. In a device of the kind described, a tubular casing having a water inlet at one end and a laterally opening water outlet some distance from the inlet, the other end portion of the casing being entirely closed except for a restricted opening communicating with the water outlet, a valve seat formed adjacent the outlet, a valve seated in the valve s-eat, a push rod slidably mounted in the casing and adapted to push the valve away from its seat in the direction of the inlet, a threaded stem mounted longitudinally in the casing from the inlet end to the valve and the said valve being slidably mounted on the stem, a shoulder formed on the stem adjacent the valve, latches pivoted on the valve and adapted when the valve is opened to engage the said shoulder and hold the valve in this position, and means operable upon the said threaded stem for automatically disengaging the said latches and reseating the valve.

2. In a device -of the kind described, a tubular casing having a water inlet at one end and a laterally opening water outlet some distance from the inlet, the other end portion of the casing being entirely closed except for a restricted opening communicating with the water outlet, a valve seat formed adjacent the outlet, a valve seated in the valve seat, a push rod slidably mounted in the casing and adapted to push the valve away from its seat in the direction of the inlet, a threaded stem mounted longitudinally in the casing from the inlet end to the valve and the said valve being slidably mounted on the stem, a shoulder formed on the stem adjacent the valve, latches pivoted on the valve and adapted when the valve is opened to engage the said shoulder and hold the valve in this position, and means for automatically disengaging the said latches and reseating the valve, the same comprising a carrier member freely mounted on the said stem, angularly set and twisted wings pivoted on the carrier and normally hanging free and downward against the member but adapted by the rush of water through the casing to swing outward and impart a rotary movement to the carrier member, the said wings having small fingers at their ends adapted as the wings move outward to mesh with the threads on the stern and cause said rotary movement of the carrier to move the same up the stern, and the end of the carrier being tapered to engage and release said latches and as the carrier reaches the end of the stern.

3. In a device of the kind described, a tubular casing having a water inlet at one end and a laterally opening water outlet some distance from the inlet. the other end portion of the casing being entirely closed except for a restricted opening communicating with the water outlet, a valve seat formed adjacent the outlet, a valve seated in the valve seat; a push rod slidably mounted in the casing and adapted to push the valve away from its seat in the direction of the inlet, a threaded stem mounted longitudinally in the casing from the inlet end to the valve and the said valve being slidably mounted on the stem, a shoulder formed on the stem adjacent the valve, latches pivoted on the valve and adapted when the valve is opened to engage the said shoulder and hold the valve in this position, and means for automatically disengaging the said latches and reseating the valve, the same comprising a carrier member freely mounted on the said stem, angularly set and twisted wings pivoted on the carrier and normally hanging free and downward against the member but adapted by the rush of water through the casing to swing outward and impart a rotary movement to the carrier member, the said wings having small ngers at their ends adapted as the wings move outward to mesh with the threads on'the stem and cause said rotary movement of the carrier to move the same up the stem, and the end of the carrier being tapered to engage and release said latches and as the carrier reaches the end of the stem the threads on the stem terminating considerably short of both ends thereof whereby the fingers in the wings will turn free as the carrier actuates the latches and allow the wings to swing back inward and the carrier to return to starting position.

4. In a device of the kind described, a tubular casing having spaced water inlets and outlets, a Valve seat formed adjacent the water outlet, a valve seated in the valve seat and normally shutting off the outlet, means mounted in the casing and adapted to move the valve away from its iseat in the direction of the inlet, a threaded stem mounted in the casing from the inlet to the valve,

the said valve being slidably mounted on the stem,
