' My invention relates to new and useful improvements in a flush `valve and has for its object to provide an Vexceedingly simple and effective device of this description adapted 15 to utilize an air trapped tank of such dimensions as to be placed within the walls of the ordinary building and which will serve to deliver the proper amount of water under pressure to the bowl and automatically shut oii the flow of said water at a predetermined time.

With these and other ends in view, this in# vention `consists in the details of construction and combination of elementshereinaiter set fort-h and then specifically designated by the claims. i

In order that those skilled in the art to which this invention appertains may understand how to use and make the'sarne, I will 20 describe its construction in detail, referring by numerals to the accompanying drawings forming apart `of this application, in which:

Fig. 1 shows my improved flush valve applied Ato an ordinary bowl and connected with an air confining tank located within the wall of a building.

Fig. 2is a plan view of Fig. 1. z Fig. 8 Vis an enlarged central longitudinal section of the valve in its closed condition; the clapper valve member being left in section.

Fig. 4 is a view similar to Fig. 3, showing the valve mechanism open, said mechanism i being in section.

Fig. 5 isa central longitudinal section of the clapper carrying member.

Fig. 6 is a bottom view of the clapper carrying member.

" Fig. 9 is a central longitudinal section of `the housing into'which the clapper carrying lmember telescopes. Fig. 10 is a bottom view of Fig. 9. Fig.` 11 is aside view of Fig. 9.' Fig. 12 is an end view of'Fig. inthe direction of the arrow.

Fig. 13 is a section of the 'casing -at the line 13-13 of Fig. 3. In carrying out my invention as herein embodied, 10 represents a relatively small air 11 looking 192s.' seriaiNo. 283,578.

trapped tank which is preferably located within the wall of the ordinary building and is supplied with water at any desired point through the service pipe 11 having the valve 12 therein for regulating theiow of water to this tank. i I' From the bottom of the tank the pipe 13 is led through the wall and has threaded thereon the `union nipple 14 carrying the union nut 15 for screwing upon the threads 16Av formed on the casing 17 of the valve whereby a water-tight connection maybe readily made between the nipple and the casing as will be readily understood.`

Thebodyof the casing 17 extends downward at an angle and terminates in thedelivery pipe 18 through which water is delivered to the bowl and 19 represents an oiiset :for accommodating the stripping dog 20. rilhis dog is secured upon the spindle 21, the latter being journalled in the side walls of the oif-set in any well-known manner to prevent leakage while permitting the spindle to be turned upon its afxis. y

The spindle 21'extend-s outward at one side of the valve and is curved as clearly shown in Fig. 2 and has thereon a suitable handle 22 in proper positionfor easy access. i f

` represents theclapper adapted to close upon the `seat 24 and this clapper isv secured in any suitable manner to the carrying member 25, said member having a threaded stud 26 projecting Ythereiroin through the clapper and on which is run the counter weight 2'? for Y determining the time relative to the flow of water at which the clapper will be closed vas will behereinater explained.

The member `25 `is preferably tubular shaped having the inclined face 28 against which the clapper is secured andso that the clapper may closein substantially a vertical `positionwlfiileithis member extends outward and downward on the axial lines oi' the cas-V 'ing and projects into the housing 297 the latter having the slots 30 formed in the outer portionthereoiand through these slots passes the guide pin lcarried by the casing. This pin .while permitting vthe sliding of the hous- .ing back and forth within the casing pre- CTI ment causes the housing to move back andi forth with the clapper member while permitting said member to be tilted independently of the housing and the particular shape of the lugs 34 and the seats and angular slots prevent the disengagement of the clapper a member and the housing during the various movements thereof. a

Since the housing is held against axial rotation by the pin 31, the lugs 34 in engagement with said housing as just described will' also prevent the clapper member from rotaa Ytion upon its axis and thus always maintain the clapper in proper relative position to its seat. Y

A rib35 carried by the housing serves as a riding surface for the clapper member in its to-and-fro movements relative to the housthus preventing undue friction.

The clapper member is cut away as indicated at 36 so as to permit the free iiow of water to the interior of the member when the clapper is open and also to direct the flow of the water at an upward angle to hold the valve open as will be presently explained.

37 represents a tongue formed with the member 25 and. this tongue terminates in a heel 38 against which the dog 2O acts to force this member inward and upward in order that the shoulder 39 carried by the tongue may be brought into engagement with th shoulder 470 formed in the casing.

From the foregoing description, it will be obvious that when the handle 22 is raised, the dog 20 will. force the clapper off its seat, tilting the member 25 upon the rib 35 and enthe shoulder 39 with the shoulder 40 thereby lifting the inner end of this member and the clapper carried thereby so that the flow of water from the tank will pass beneath the clapper through the openings 36 and against the upward wall of the member 25, thus holding the clapper open as long as the force of iiow is suflicient to maintain these parts inthis position and sustain the'counter weight 27 in its elevated position; but when the force of the flow of water has been dic the water will close the clapper upon its seat shutting od any other flow.

The adjustment of the counter weight upon the stud 26 will determine the point at which the water will shut off as will be readily understood.

By utilizing an air trapped tank and providing for the-closing of the valve at a predetermined pressure iiow' of the water, not only the supply of water in the tank at the time thevalve is open will be delivered to the bowl, but the additional water which will fiow into the tank after the pressure in the latter falls below the pressure in the service pipe will also be delivered to the bowl, thus necessitating a much smaller tanlr than will otherwise be necessary; and as the water is delivered through the valve under pressure and therefore at high speed, its effectiveness in cleansing the bowl is increased, thus requiring a less quantity of water than where the ordinary gravity tanks are used.

The releasing of the handle 22 and the return of the dog to its normal position as shown in Fig. 3 prevents interference with the tilting of the member v25 and the backward movement of the tongue 37 during the closing of the clapper upon its seat.

Of courseI do not wish to be limited to the exact details of construction as herein shown, as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is 1.
