AUTOMATIC FLUSHING MECHANISM.

SPECIFICATION forming part of Letters Patent N o. 621,058, dated March 14, 1899. Application filed September 20, 1898. Serial No. 691,436. (No modell) To all whom it may concern:

Be it known that I, JOSEPH W. FRY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Automatic Flushing Mechanisrn; and I do declare that thefollowing is a full, clear, and exact description of the invention, which Will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in automatic flushing mechanism forwater-closets; and the improvement consists in the peculiar construction and novel combination of parts, substantially as hereinafter described, and more particularly pointed out in the claims.

The object of the invention is'to provide a water-closet bowl with an automatic arrangement which will ll the flushing-tank with water when the seat is occupied and discharge the Water with sufficient force to fiu'sh the bowl when vacated.

In the accompanying drawing the single ligure is a side elevation of a bowl with the flushing-tank and valve mechanism shown in section.

The bowl 2 is of any desired form or construction, but preferably of the kind which has a hinged seat-cover 3 at its top. At the back of this bowl and also resting on the top thereof is the Iiushing-tank 4, which has its outlet 5 connected directlywith'the flushingrim of the bowl. The'water-supply pipe 6 leads from the bottom of the tank 4 down to and beneath the floor to a governing-valve 7, centrally located at the front and also beneath the floor. This Valve 7 could be placed above but is preferably arranged below the iioor to avoid exposure to the elements, especially where the bowl is placed in an outhouse or the like, where freezing is likely to occur. The governing-valve 7 is provided with a supplychamber 8 and a waste-chamber 9, and these chambers are divided by a wall 10, which has Valve-seats in each side ofits face, and the chambers are connected by an open passage 11, leading from seat to seat. A stem 12 passes centrally through the passage and out through a bushing at the top of the Valve 7 and extends up and against the bottom and outer end of the'seat-cover 3. Valves 13 and 14 on the stem 12 are arranged within the chambers 8 and 9, and when one of the said valves is on its seat the other is oft' and open.

The main supply pipe and inlet to the governwhich the Waste water in the local supplypipe 6 is drawn olf through the Waste-pipe 15, leading from chamber 9 to the main outflow 16. As soon and as long as the seat 3 is occupied the stem 12 is depressed, valve 13 is open, and valve 14 closed. The waste-passage is thus cutoff, and the Water is free to enter supply-pipe 6 and pass to the flushing-tank 4, where it irst enters a piston-chamber 10 before discharging into the tank proper. The Water enters the bottom end of the pistonchamber, and the force of the same comes head on against the end of the piston-valve 17 and carries the piston up and beyond openings 18, through which the water then discharges into tank 4. The pressure of the Water keeps the piston up in raised position and is utilized to close the flush-valve 19 and keep it .closed until it is released, as hereinafterdescribed. In'the meantime the tank fills toits limit, which limit is controlled by an air-valve 18 and float 19. As the water rises the float is carried up until air-valve 1S is closed. The water will continue to rise under its own pressure and compress' the air within the top of the now air-tight tank, and the forced water-level obtained is maintained until the occupant vacates the seat 3 and the pressure upon valve 13 closes the said valve and cuts off the Water-pressure on the piston- Valve 17 and allows the flush-pipe valve to be opened. The Water will then iiow rapidly and with force out of outlet 5 and flush the bowl.

The operative connectionV between piston- IOO valve 17 and valve 19 consists of a link 20, pivotally connected to the apex of the conical hinged valve 19 and to the end of the pist0n-stem 21. A spring 22, within the pistonchamber 16, bears on the piston, and when the water is cut off forces piston-Valve 17 down and opens valve 19, as seen in full lines. The back of the valve is cone-shaped, as described, to decrease the amount of resistance in opening the same occasioned by the weight and pressure of the water in the tank. This form of valve allows a quicker action with less pressure of water against the piston to operate the said parts.

The advantages of a fiushing mechanism constructed and arranged as described are as follows: The closetv whenever used is sure to be automatically flushed without the attention or care of the occupant, the tank and exposed pipes are free from water at all times except when the seat is occupied, preventing freezing or chance of leakage, and the construction as a whole is so simpleV and compact that it is both convenient and durable, as well as efficient in operation.

lVhat I claim as new, and desire to secure by Letters Patent, is-

1. In water-closets, a flush-tank and an outlet-Valve therefor, a Water-inlet chamber for said tank, and a supply-pipe thereto, a valve in said inlet-chamber constructed to be raised by water-pressure to establish flow of water to the tank, and a spring to restore the Vinlet-valve to its seat when the supply-pressure is cut off, and connections'between said outlet-valve for the tank and the inlet-Valve for the said chamber, substantially as described.

2. The combination of the closet-bowl and seat and the flush-tank and inlet-chamber therefor, a water-supply pipe to said chamber and a valve to close. said water-supply having operating connection with the said seat, and connected inlet and outlet Valves for the flush-tank, substantially as described.

3. Flushing mechanism for water-closets comprising the bowl and seat, a flushing-tank, a water-supply-governing Valve and a stem therefor, said valve arranged to be closed by water-pressure, in combination with an outlet-valve within the flushing-tank and an inlet-valve connected therewith, substantially as described.

4. Flushing mechanism for water-closets comprising a water-supply pipe leading to the ushing-tank and a governing-valve therefor constructed and arranged to be kept closed by the water-pressure, in combination with a flushing-tank and an outlet-Valve therefor, an inlet-chamber for said tank and a Valve therein, and pivoted connections between said Valves, substantially as described.

5. The bowl and the seat thereon, flushing mechanism comprising a flushing-tank, a water-supply-governing valve and a rod therefor extending to the seat, said Valve arranged to be kept closed by the pressure of the water, a piston-Valve chamber within the flushingtank, a supply-pipe leading from said chamber to said governing-Valve, a spring-pressed piston-valve Within said chamber, a flushingvalve hinged and seated at the outlet of said tank, a link connection between said piston- Valve and flushing-valve, and an air-valve inv the top of said tank, all said parts combined and operating, substantially as described.

6. Acloset-bowl andailushing-tankmounted thereon, a hinged seat for said bowl, a set of water-supply and waste chambers, Valves within said chambers and a stem connecting said valves and arranged to engage the said hinged seat and be depressed thereby, thc Valve within the supply-chamber being seated opposite the water-inlet and constructed to be kept closed by water-pressure from the main, in combination with valve mechanism within the flushing-tank comprising a conical-shaped flush-valve and a float-controlled air-valve, and a chamber and piston-valve in said chamber, and a link and pivoted arm connecting said piston-valve t and the said flush-valve and a spring to close the piston- Valve and open the Hush-valve in the same action, substantially as described.

Vtfitness my hand to the foregoing specification this 3d day of September, 1898.

A JOSEPH WV. FRY.
