T 0 all whom t may concern Be it known that I, JOHN HEARL, a citi- Zen of the United States, residing 'at Baltimore, State of Maryland, have invented vcertain new and useful Improvements in Flushing Apparatus for 7Water-Closets, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements in flushing apparatus for water closets, and more particularly to a flushing device which is frost-proof.

An object of the invention is to provide a device of the above character wherein the supply valve and the flushing valvel are'independently mounted and controlled by the seat, the flushing valve being disposed'so as to operate horizontally.

A further object of the invention is to provide a device of the above vcharacter wherein the flushing valve is'controlled directly by a cam shoulder on the seat and wherein the flushing valve is heldby a lim iting stop away from the casing when forced open by the water pressure.

A still further object of the invention is to provide a device of theV above' character with a spring for holding the flushing valve slightly unseated. i

In the drawings, which show by way of illustration one embodiment of the invention,-Figure 1 is a view partly in section and partly in side elevation, showing a closet having my improved flushing apparatus applied thereto; Fig. 2 is an enlarged detail in vertical section through the upper valve casing, showing the parts in position for supplying water to the tank; Fig. 3 is a detail showing the flushing valve as unseated by its controlling spring; Fig. 4 is a similar view, showing the valve in full open position resting against the limiting stop.

The invention consists broadly in providing a flushing device having a supply controlling valve located below the frost line and a flush controlling valve located substantially at the line of the seat, both of which valves are'simultaneously operated by the seat, so that when the supply controlling valve is opened by the depression of the seat the flush controlling valve is closed, so as to direct the waterto the air tank,.and when the seat is raised so as to allow the supply valve to close, then the flush controlling'valve is opened by the water pressure as it rushes from the tank to the hopper. The water from the supply passes through a pipe connected to the upper valve casing and the valve stem for the valve controlling the supply extends upwardly through this pipe. The spring for depressing the valvey is located outsideA of the pipe, so that no water accumulates in the spring to freeze and render the device inoperative. The flush controlling valve is mounted so as to move horizontally, and is located substantially in the plane of the seat, so that the same may be engaged directly by a cam shoulder' on the seat arm. Means is also provided for normally holding the flushing valve slightly off from its seat, and also for limiting the movement of the flushing valve through thel action of the water so it is held spaced from the valve casing. i

` Referring more in detail to the drawings, my improved flushing device is shown applied to a closet having a hopper 1 and a seat 2. The supply pipe is indicated at 3. This supply pipe is connected to the lower valve casing 4 whichv is located below the frost line. The lower valve casing 4 has a valve seat 5, which is adapted'to be engaged by a valve 6. rlhe valve 6 is attached to a valve stem 7 which extends upwardly through a pipe 8 screwed into the lower valve casing 4. rlhe lower valve casing 4 is provided with a by-pass 9, so that when the valve 6 is raised the water from the supply pipe 3 will pass through said by-pass and up around the stem 7 in the pipe 8. The pipe 8 at its upper end is attached to a E"-coupling 10. A pipe 11 is suitably connected toi-,his T -coupling at one end, and at its otherend is connected to an air pressure tank 12. rPhe water from the supply, when the supply valve is open, rushes into the air tank which is substantially a closed tank, compressing the air therein which expands when the supply valve is closed for forcing Y the water through the pipe 11 to flush the hopper. rlhis type of closet iswell known, and further detailed description of the operation of the tank is not thought necessary.

Attached to the hopper'spud 13 is an upper valve casing 14. Said upper valve casing 14 is connected to a pipe 15 threaded into the T-coupling 10 by a flanged sleeve 16, cooperating with the flange on the upper end L 60 stufling box 38.

of the pipe 15. This connection permits the T-coupling tobe set so that the pipe 11 may be connected thereto directly in rear of the pipe 8, or at one side thereof as the conditions demand. The valve casing is provided with a suitable water-tight packing gland 17, which will be referred to more in detail later. Moving in thisl packing gland is a coupling sleeve 18, secured to the valve stem. l15in expansion rod 19 is threaded in the upper end of this coupling sleeve. An open cage is threaded onto the upper end of the valve casing 14 and this cage serves as Yan abutment for the spring 21 which holds the valve stem 7 depressed. Said cage kat its upper end is threaded to receive a sleeve 22 which is closed at its upper end and formed with square shoulders serving as a means for adjusting the position of saidsleeve. The spring 21 extends into this sleeve and bears against itsk upper closed end. Said `spring at its other end bears against a washer 23 which restsl on the upper end of the coupling 18. VThis sleeve 22, as above noted, may be adjusted in the cage andis locked in adjusted position by a lock nut 24. By adjusting the 'position of the sleeve 22, the pressure of the spring 21 may Y be varied and'thus the pressure of the valve 6 against its seat Ymay be Vadjusted to correspond with the water pressure in the supply main.'` y

`'The valve casing 14 is formed with a downwardly and outwardly projecting arm 25 which is secured to the hopper spud 13 by a clamping collar 26 of the well known construction. The seat 2 is'screwed to a seat iron 27 and this seat iron is formed with forked arms 28 extending each side y of the valve casing. A pivot `bolt 29 passes through a suitable lug 30 formed on the valve casing vand also through the forked serves as a support for the seat.

treme outer ends of the arms 28 are curvedk arms 28 of the seat iron. VThis pivot bolt The eX- and also enlarged so as to weight the same. These curved arms-engage a cap 31 fixed to the rod 19 which is an extension of the valve stem 7. The cap 31 is secured to this valve The-valve casing 14 is forniedrwith a port .l 34 which connects the main part of the valve valve seat.

casing with the arm- 25. The outer face of the port 34 is provided with a valve seat 35 and a valve 36V is adapted to engage this Said valve 36 is carried by a stem 37 which passes throughl a suitable On the outer end of the valve stem 37'is an adjustable knob 39. This knob is threaded onto the valve stem and isy held in adjusted position by a set screw 40a.-

, The knob is rounded off and is adapted to V be engaged by a cam face 40 on the seat iron 27. A spring 41 may be placed between this i.

knob and the stuffing boX.- The spring, however, is of sufficient length and tension merely to hold the valve slightly unseated when it is not, closed by the depressing of the seat. The valve is moved to open posi- Vtion by the water pressure. A limiting pin A42 is secured to the valve casing in position so that when the valve is forcedto openv position by the water, it will engage the valve and hold the same spaced away from the casing. This prevents the valve'freezing on its seat, and also prevents the valve freezing against the casing.

The packing gland 17 consists of a sleeve 43, threaded into the valve casing, a rubber sleeve 44 which rests against a shoulder 45 of the valvev casing and projects downwardly below said shoulder, a washer 46 of metal and a suitable packing washer 47. The I' with a projecting flange 48 at its lower end.'

This iiange ywhen the valve stem is raised is adapted to engage the lower endof the rubber sleeve 44 and further linsurea watertight joint at this point in the valve casing, when the valve casing is subjected to the water pressure from the supply, thatis, during the` filling of the tank.

i When the seat 2 is depressed theV valve 36V Y l through the action 'of the cam face 40 on the knob 39 will be forced inwardly, and this will seat the valve and close theV port 34. This same movement of the seat causes theV arms 28 to engage the cap 31H andraise vthe valve stem 7, unseating the valve controlling the supply and permitting the water from the supplyto pass through the by-pass 9:V

thence through the pipe 8 and the'pipe 11 to the tank 12. The amount of water enteringthe't'ank 12 will depend upon thevpressure `of the water main. When the seat 2 is released the spring 21 will operate to depress the valvestem 7, seating the valve 6 and cutting olf the supply. The water from the tank through the action vof the expanding air therein unseats the valve 36, which is now released and passing through the hopper spud flushes the hopper. After all the water in the tank has passed into the hopper, the water remaining in the pipe 8 and below the hopper spud willfpass through the drainV opening 42L and the vpipe 43l to the hopper liaY waste'p'ipe.` The valvestem 7 is'provided with a cylindrical valve 44ZL which closes tne waste opening 42a when the supply valve is raised, so as lto prevent the water from thek supply escaping through the drain pipe 43th This cylindrical valve 44a, however, uncovers the wasteV openingwhen the supply valve is seated.

ist

It will 'be noted from the above description, that the valve for controlling the flushing water is unseated by the pressure of the water. lThis Vvalve is also operated independently of the supply controlling valve, although simultaneously therewith, by the movements of the seat. Said valve is located substantially in the plane of the seat, so that it may be engaged directly by the seat iron, thus reducing to a minimum the number of parts and thereby the eiliciency of the apparatus. It will further be noted that the Varm of the valve casing which carries the flushing water to the hopper, extends generally in a downward direction from the port 34, so that all the water in the valve casing will drain either through this down wardly projecting aan into the hopper, or downwardly through the vertical part in the valve casing and the pipe 8 to the drain pipe 43a. lt will also be noted that the flushing valve is held vslightly away from its seat, which prevents any water from accumulating or being trapped by the valve through an incomplete or improper depressing of the seat, and by the limiting pin or stop which holds the valve away from the casing likewise any liability ofwater trapping around the valve is prevented.

It is obvious that minor changes in the details of construction and the arrangement of parts may be made, without departing from the spirit of the invention as set forth in the appended claims.
