FLUSHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 605,712, dated .Tune 14, 18.98.

Application filed July 30, 1897.i Serial No. 646,501. (No model.) l

To au whom it may concern.:

Be it known that I, HENRY HAYNEsVof Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement' in Flushing Apparatus, of which the following is a full, clear, and exact description. v

The object of my invention is to provide a flushing apparatus especially adapted for use with Water-closets; and the object of the invention is to provide'an apparatus of such description in which the water will be admitted to the tank while the seat of the closet is pressed down or during the period that the closet is in use and whereby Whenthe seat is relieved from pressure the water will immediately iiow from the tank into the bowl.

Another object of the invention is to provide a system of valves for controlling the supply of water to the tank and the discharge of water from the tank to the bowl,'whicl1 system of valves will be exceedingly simple, durable, and economic, and, furthermore, to provide a simple means for operating the said valves by raising and lowering the closet-seat.

The invention consists in the novel construction and combination of the several parts, as Will be hereinafter fully set forth, and pointed out in the claims.

Referenceis to be had -to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding partsin all the figures.

Figure 1 is a vertical section through a iiushing-tank having the improvement applied and a side elevation ofthe valve-casing, the discharge-pipe, and the connections between the said pipe and bowl and the pull-rod and seat. f Fig. 2 is an 'enlarged-vertical sec.

tion through a portion of the bowl and through that portion of the apparatus which is adjacent to the bowl.- Fig; 3 isV an enlarged transverse section through the tank, the loat, and air-valve casing for the tank, and likewise a vertical section through the casing for the supply and discharge valves of the tank and through the water inlet and discharge pipes.v

Fig.`4 is an'enlarged'vertical section through a portion of the tank, the discharge and supply valves, and their casings, and Fig. 5 is a horizontal section through a slghtly-modilied form of thevalvemechanism adapted to be placed ina position removed from the flushing-tank and under the seat, which is shown 4in plan.

The flushing-tank A may be made of any suitablematerial and is air-tight. An opening is made in the top of the tank, which opening receives a casing 10. The bottom portion of the casing is of greater diameter than the top and is provided with flanges 11, arranged for attachment to the inner face of the top of the tank, and slightly above the flanged portion Vof the casing an annular and preferably conca-ved valve-seat 12 is produced.` Below the casing within the tank a guide-plate 13 is horizontally supported and spaced from the casing 10 by bolts l15 and sleeves 14. A iioat 16,v preferably iiat, is provided With a stem 17, which extends upward through an opening in the guide-plate 13 and the top of the casing 10. A valve 18 is secured on this stem, adapted to control the supply Y of air to the flushingftank, and this valve usually consists of 'a disk,which is secured on the stem, and as'eniispherical elastic body erably interiorly-threaded flange, as shown in Fig. 4. The plate 19 has' anfopening 2O in its central portion,and the bottom edge of the said opening is cut away to form a concaved annular valve-seat 21. (Shown also in Fig. 4.) A` casing 22 is attached to the valved portion of the plate` 19, and the bottom portion of said casing is contracted, forming a neck 23, eX- teriorly threaded, as shown in Fig. 3. A second plate 24 is located above the plate 19, attached to the flushing-tank- This plate 24 is provided with an upwardly-extending iiange 25, which receives vthe lower end of an upwardly-extending casing 26, this lattercasing being entirely Within the tank. The pl'ate 24 is separated from the plate ,19 andi isi held in position by bolts 28' and sleev`es'27. (Best shown in Fig. 4.)

An opening 29 is made in the central portion of the upper plate 24, and the upper edge IOO 'second section Jr() of the valve-stem is IAO of the said opening is cut away to form an anl nular concaved valve-seat 30. A spider-guide 3l is secured at the neck portion of the lower casing Bland a similar guide 32 is placed within the upper casing 2b' near its top. A valve-stem 33 extends within the lower casing and practically through the upper casing, passing likewise through the openings in the two plates l0 and 2l. This valve-stem carries a lower discharge-valve 3l and an upper supply-valve S5, one being adapted to open when the other closes. The lower or discharge valve 3l is larger than the upper or supply valve 35, but both valves are practically ot' the same construction, each comprising a metal disk a, which may be connected with the valve-stem, and a semispherical elastic body a. The lower discharge-valve 3l seats when carried upward, and the upper or supply valve 35 seats when it is carried downward. A sleeve 315 is slipped over the valve-stem 33, being placed between the two valves, and at each end of the sleeve a ilange 37 is made, one of: the [ianges engaging with the dischargevalve and the other flange with the supplyvalve, as shown in Fig. l.

A pull-rod 3S is screwed upon the lower end of the valve-rod 33 to an engagement with the lower or discharge valve, holding the latter in place, and a union 39 is screwed upon the upper end of the valve-stem 33, serving to hold the upper or supply valve in place. A

screwed into the union 39 and passes through the upper guide 232, the pull-rod 3S passing through the lower guide 3l, as shown in Fig. 3. This lower guide 3l insures the valves sliding through to their seats.

The water-supply pipe 50 is passed usually through a side of the tank and is secured in the upper end of the valve-casing 26, as illustrated in Fig. 3. A discharge-pipe 5l is secured to the lower end of the lower valvecasing 22. This discharge-pipe is of anydesired diameter and extends downward, usually through a support 52, attached to a wall or adjacent tothe closet-bowl 53. The lower end of the discharge-pipe 5l is suitably shaped to enter the bowl. At the bend of the discharge-pipe 5l a stufling-box 5l is formed, through which stulling-box the pullrod 3S passes. The lower end of the pull-rod is provided with a head 55, and a spring 5G is coiled around the pull-rod, having bearing against the said head and against the stuffing-box. This spring serves to keep the upper or supply valve from leaking during low pressure in the water-main, and the spring likewise serves to assist in holding up the front of the closet-'seat when the latter is not in use.

The seat 57 is connected with the support 52 or with an equivalent support by means of a hinge 5S of suitable construction, and the seat is so mounted upon the support that it will have normally at least an inch play to and from the bowl. The pivot 5S) of the hinge is above the level of the seat, and the upper end of a lever 60 is loosely mounted on the pivot-pin of the hinge, extending downward through an opening inthe hinge and an opening 6l, provided between the rear of the scat 57 and the support 52, as shown in Fig. 2. The upper end of the lever GO is preferably at an angle to its body, and the straight-forward edge of the lever just beneath the anguiar top is adapted for engagement with the back ot the seat 57, and in order that the lever shall not mar the seat a protecting-plate 2 is attached to the seat opposite the lever, as is also shown in Fig. 2. The lower end of the lever 60 is provided with a longitudinal slot G3, in which a pin (il is adjustably secured, and said pin is connected with a link G5, the link beingpivotallyattached to an arm 0f a bell-crank lever fill, the opposite arm of the lever being pivotally attached to the head of the pull-rod.

In operation when the seat 57 is unoccupied it will be raised at its outer end, as the spring 5G, pressing downward on the horizontal member of the elbow-lever GG, will cause the said elbow-lever to force the lever Gl) forward and thereby carry the seat to an upward inclination at its forward edge, and the spring 56 will likewise serve at that time to keep the su pply-valve 35 closed and the discharge-valve f3'- open, so that all the water that may have been contained in the tank will have ilowcd out through the discharge-pipe 51 into the bowl. The adjustable pin 6l, connecting the link G5 with the lever (50, is made adjustable in order that the throw of the valves may be controlled from said lever. lVhen the seat is pressed downward onto the bowl, the seat as thus forced downward will force the lever GO rearward and cause the elbow-lever GG to force the pull-rod 38 upward against the tension of the spring 5G, thereby causing the dischargevalve 3i to close and the inlet-valve to open, as shown in Fig. 4C. The result will be that while the lid is held down the water will flow into the tank until it has reached such a level as to cause the iioat to close the air-valve 18, and in a short time the air-pressure in the tank will become equal to the water-pressure in the supply-pipe and the supply of water will cease. As soon as the lid is released from pressure the spring 5G acts on the lever G0 to throw the seat up and unseat the dischargevalve 34, closing the supply-valve 35, and, as stated in the first place, all the water in the tank will flow downward to the bowl.

In the construction shown in Fig. 5 the arrangement of the valves is especially adapted to admit of the valves being placed at a point below the seat and at the rear of the bowl. This construction embraces a valve casing 68, into which the discharge -pipe G7 enters near one end and is connected with the bowl. Vithin the casing, just in front of the entrance of the discharge-pipe G7, a vertical partition 60 is formed, havingan opening therein, at which opening a discharge-valve is adapted to be seated. Parallel with the par- ICO TIO

tition 69 a .second vertical partit/ion 7l is `formed in the casing, having an opening at which the inlet-valve 72 is to be seated, the inlet or supply valve being at the outside of lthe partition 7l, while the discharge-valve 70 is at the outside of the partition 69.

, partitions 69 and 7l, and the water-supply pipe 76 is connected with the casing atY that end near which the inlet-valve 72 is placed. The two valves are secured upon the saine stem l73, and this stein is coupled toa pullrod 74, passed through a bushing 75 at the end of the casing, the pull-rod terminating in a head 55 the same as the pull-rod in the other views heretofore described. The outer portion of the pull-rod is surrounded by a spring 56, acting in the same inanner as the spring designated by the same reference-numeral in the other views. The head portion of the pull-rod is connected with a bell-crank lever 77, and the said bell-crank lever is connected by a link-'7S with a seat-lever 60.

Having thus described my invention, I

l claim as new and desire `to secure by Letters cap having a valveseat forined therein, connected valves, one valve being arranged to close the outlet for the water-supply pipe and the other valve being arranged to close the inlet of the discharge-pipe, one valve seating when the other is unseated, and a pull-rod connected with the valve, whereby the valves are operated, for the purpose specified.

2. In a lushing apparatus, the combination, with a tank, a water-supply pipe leading into the tank, the said tank being provided with -an opening in its bottom and a plate having a valve-seat supported within the tank above the opening, forming a cap for the outlet end of the supply-pipe, of a discharge-pipe iitted in the opening in the tank and provided at its top with an apertured cap having a valve-seat formed therein, con-Y nected valves, one valve being arranged to close the outlet for the water-supply pipe and the other valve being arranged to close ,the inlet of the discharge-pipe, one valve seating when the other is unseated, a pull-rod connected with the valve whereby the valves are operated, a tension device normally holding the pull-rod in a downward direction, causing the supply-valve to be normally seated, a lever, and a connection between the said lever and pull-rod, whereby the said rod may be forced upward against the resistance of the said tension device, as and for the purpose specified.
