Nov. 17, 1936. J. J. GooDRlE FLUSHING VALVE ITI ZZV/lll Filed Feb. 3, 1934 l IIIIIIIJ Patented Nov. 17, 1936 UNITED STA'ES PATENT GFFIQE 15 Claims.

'This invention relates to an improved silent flushing valve, particularly adapted for toilet bowls and the like, and has for one of its principal objects, the provision of a flushing valve which, besides eliminating the necessity for the ordinary toilet bowl with the float and other appurtenances, will constitute a very silent, and, therefore, satisfactory mechanism.

One of the important objects of this invention is to provide a. flushing valvefor toilets or the like which shall be compact, economical to manufacture, easily installed, and which will not be likely to get out of order.

Another and further important object of the invention is the provision of a flush valve for toilet bowls and similar equipment which, on account of its simplicity of construction, can be readily assembled and as readily taken apart in the event that cleaning or repairs ever become necessary, and furthermore, one in which the needle valve, which has heretofore been considered as a necessary evil in these devices, shall be so constructed that it is quite unlikely tok ever become plugged or stopped, and if this does happen, the construction of this needle valve is such that it can be readily removed for cleaning or replacement.

Another and still further important object of the invention resides in the provision of a flushing valve of the type described wherein all the parts can be readily removed while the casing is still in rposition in the pipe line, thereby rendering inspection `and repairs quite easy and simple, and one which, furthermore, includes a manually operated time adjustment for the length of the -flushing operation, whereby the same can be regulated as occasion arises or as necessity requires.

A still further and. not the least important object is to provide a flushing Valve which will deliver a considerable volume of water even under a small head or pressure, and even when used with an intake pipe which is of less diameter than usual.

Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawing and following specication.

The invention, in a preferred form, is illustrated in the drawing and hereinafter more fully described.

In the drawing:

Figure l is a vertical sectional view of the improved silent ushing valve of this invention, showing the same in closed position.

'Figure 2 is a vertical sectional view teken on a (Cl. 137-93) l plane at an angle to the plane of the section of Figure l, showing other operating parts and also showing the valve in open position.

Figure 3 is a greatly enlarged section showing the removable nozzle for the capillary or similar tube which controls the length of the flushing operation.

As shown in the drawing:

The reference numeral Ill indicates generally the casing of the improved flushing valve of this invention, the same being preferably closed by a removable cap vI2 at the top and having a water outlet opening I4 at the bottom and a water inlet opening I6 at the side.

Slidably and removably fitted into the interior of the casing I is the body I8 oi the valve which comprises essentially a cylindrical structure having a piston 20 slidably and removably mounted in its lower end.

Depending from the piston 20 by means of a connecting shaft 22 or the like is a valve element 24 which has mounted therein a resilient valve member 26 which is adapted to fit into a valve seat 28 formed in the interior and lower portion of the outer casing I0. A guide 30 is provided for the piston and valve, this being preferably in the form of a four-flanged element as best shown in Figure 2 whereby free passage of water through the opening outlined by the valve seat 28 is permitted when the valve 24 is up. The upper end of the casing I8 is formed to dene a chamber as shown at 32 which is open at the top to form a valve seat 34 and mounted in this valve seat is a tiltable valve element 36 having a central stem Adapted to operate against this central stem 38 is a push-rod 40 mounted vin a support 42, the push-rod being normally held in retracted position by means of a helical spring 44.

Adapted to operate against the push-rod 40 is an operating rod 46 fitted in a bearing 48 which bearing is, in turn, mounted in a support 50 for a handle 52.

The handle 52 is mounted for universal tilting movement in a housing 54 on the end of the support and operates against a head 56 positioned l ment and repairs and which jet empties into the space 66 interiorly of the inner casing I8 and above the piston 20.

When the valve 36 is open, water in the space 66 is allowed to iiow into the space 68 in the chamber 32, but inasmuch as a channel 'l0 leads from this space 68 to the outlet end I4 of the Valve, no water ever accumulates in the space 68.

Normally, when the valve is closed, water from the intake pipe I6 flows into the space 62 and also into the capillary tube 60 through the nozzle 64 into the space 66 above the piston 2U, thereby holding the piston down in valve-closing position.

When the valve 36 is opened through the action of the handle 52 tilting the stem 38, the water in the upper end of the space 66 is allowed to flow into the chamber 68, thereby releasing the pressure above the piston 20, and the pressure of the in-coming water in the space 62 raises the piston 20, accordingly opening the Valve 24-26. Water then iiows through the intake pipe I6 directly past the Valve and out through the opening I4, thereby flushing the toilet or performing any other desired operation. In the meantime, the return of the handle 52 into normal position allows the valve 36 to close, and the small iioW of water through the capillary tube 60 will then accordingly in a predetermined length of time, iill the space 66, forcing down the piston 20, and finally again closing the valve 26, whereupon the apparatus is again ready for operation.

The distance of upward movement of the piston 20 can be manually regulated by means of the set screw 12 which is mounted in the piston head and held in adjusted position by means of a lock nut or the like 14. In this way, the length of time of the iiushing operation may be controlled, and this may also be controlled by the size of the opening 16 in the removable jet or nozzle element 64.

The iiushing valve of this invention is particularly quiet and efficient in operation and is not likely to get out of order, and even if it does so become out of order, repairs can be quickly and economically effected even by one not skilled in the art. Furthermore, the construction is comparatively simple and will thereby produce an economical valve having desired qualities of durability and neatness. The large size of the opening immediately made available by the initiation of operation enables a considerable Volume of water to pass through the valve, and therefore, a satisfactory flushing operation will be consummated even under a relatively light head or low pressure of water.

I ammaware that many changes may be made and numerous details of construction varied throughout a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.
