FREDERICK JOHN MORGAN, OF OLAREDENE, MAIDENHEAD, ENGLAND.

WATER-WASTE PREVENTER.

Application filed May 22, 1908.

T o all whom it 'may concern:

Be it known that I, FREDERICK JOHN MORGAN, a subject of the King of Great Britain, and resident of Claredene, Clare Road, li'laidenhead, county of Berks, England, mechanic, have invented new and useful Improvements in )VatergWaste Preventers, of which the following is a speciication.

The present invention relates to that class of water waste preventer or flushing tank for lavatories and the like which is normally empty and which fills and discharges only when operated by means of a handle or otherwise.

The advantages of the normally empty tank are many and obvious but there are also difliculties notably in securing a satisfactory discharge of water automatically when the tank has been filled.

My invention consists in the construction of water waste preventer and arrangement of parts now about to be described.

Figure 1 represents my invention in plan view, the cover of the tank being removed. Fig. 2 is a. section on line A-A of Fig. 1 and Fig. 3 is a section on line B-B of Fig. 2. Fig. 4 shows the water inlet valve detached on an enlarged scale.

(L is a tank or cistern having a removable cover i). c is a water pipe leading thereto and d is a valve casting embodying the inlet pipe e which cast-ing is attached to the pipe c by means of a screw union f outside the tank a.

g is a water inlet valve having a conical head closing down on its rubber lined seat (see Fig. 4) under the pressure of the water supply.

71, is the spindle of the valve projecting into the interior of the tank.

The valve casting as well as the cistern is normally empty and will not therefore freeze in frosty weather.

The water pipe c which is outside the cistern can always be lagged without difficulty. On the lugs z' attached to the casting (Z is pivoted the float lever j which has in one with it the arm 7c. This arm le is pivoted to the valve spindle 71. at Z. m is a hook on the arm k (see Fig. 2). A

a is a rocking shaft arranged transversely of the tank in suitable notches or bearings. Fast to this shaft is the chain lever 0 and also the weighted lever p the nose p of Specification of Letters.Patent.

which is adapted to engage with the hook m of the arm le.

g is a siphon fitted in a well in the bottom of tank a. It consists of the vertical pipe 7 open at the top and connected to the flush pipe at the bottom, the cap s inclosing the pipe 7 and an air pipe t extending from the outside of the cap near the bottom to the interior thereof near the top above the level of the top of the pipe a. n the present instance communication between the pipe t and the interior of pipe 7' is established through a perforated plate 1" held in the top of pipe r by means of a bolt r2 passing through the upper end of the cap s and engaged by a nut r3. This siphon will always discharge automatically when the tank is filled and will obviate the use of an overflow pipe. There is preferably a hole in the pipe r near the bottom of the well so as to insure that the latter shall be normally dry. This may either be a very small hole which is not large enough to appreciably retard the lling of the tank or it may be a larger hole furnished with a plug as at o which is raised by the ball or float descending on the end of the plug lever w when the tank is empty. This drainage hole is useful in the case of severe frosts.

When the flush is required the chain of the lever 0 is pulled thereby rocking the shaft a and depressing the nose of the weighted lever p which strikes the incline of the hook m, tilts the same backwards and opens the valve g and retains it open by engaging beneath the said hook (see dotted position of Fig. 2). The water running in lills the tank and raises the Hoat lever y' causing a further backward tilting of the arm lo. The same movement opens more widely the inlet valve and the siphon being overflowed, automatically discharges.

u is a closed air vessel for preventing shock in the water pipe when the valve is shut by the pressure of water behind it on the descent of the float lever. The weighted lever p falls back against its stops (not shown) when its nose clears the hook m and the tank is then ready for the next flush.

What I claim and desire to secure by Letters Patent of the United States is z* 1. In a normally dry water waste preventer or flushing tank, a self-closing inlet valve; a pivoted hook lever connected thereto, a weighted lever provided with a nose for tipping the hook lever (so as to open the valve) and retaining it in a tipped position, an operating device for rocking the weighted lever, a float lever for disconnecting the hooked lever from the nose of the Weighted lever and an automatic siphon discharging itself when a predetermined water level in the tank is reached, substantially as set forth.

2. In a normally dry Water Waste preventer or liushing tank, an inlet valve, a pivoted hook lever connected thereto, a Weighted lever provided with a nose for tipping the hook lever (so asy to open the valve) and retaining it in a tipped position,

an operating device for rocking the weighted lever, a ioat lever for disconnecting the hooked lever from the nose of the Weighted lever and an automatic Siphon discharging itself When a predetermined Water level in the tank is reached, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
