FLUSHOMETER.

Application 'filed September To all lwhom t may concern.'

Be it known that l, JOHN Rochas, a citizen` of the TJnited States, residing at Devon, in the county of ll ew Haven and State of Connecticut, have invented certain new and useful lmproveinents inv Flushorneters; and l do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains, to make and use the same.

rlhis invention relates to llushometers, and it consists in certain details of construction to be particularly pointed out in the following specification.

Referring to the accompanying drawings wherein the saine figures of reference indicate lilre parts throughout the several views,

Figure 1 represents a closed central sectional view of the ilushometer, brolren view of its discharge pipe and broken view partly in section of the supply pipe:

Figure 2 is a similar View showing the device open, and

Figure 8 is a cross sectional View on line 3-3 of Figure 2.

1 represents the casing divided into the three

chambers

2, 3, and 4. ln chamber 2 is located the valve actuating plunger 5 having a reciprocating movement therein. In chamber 3 is located the flush valve 6 communicating with the discharge or flush chamber 4, and also a relief valve-presently to be described-coinmunicating with the interior of the plunger. The valve 6 carries the heads 7 and 8 guided in the projections 9. rllhe lower head having the taper face 10 adapted to register with the valve seat 11 formed in the partition 12. The upper head 8 registers with the relief valve 13 guided on the stationary stem 14. 15 is a seat in the partitions 12 and 12a for said relief valve opening into the passage 16, which passage connnunieateswith he interior of the plunger through the openings 1'4". 18 is a screw spanning the passage 16 to regulate the amount of water entering the plunger during the `llushing operation.

The cap 19 has the air vent 2O adapted to be closed by the valve 21 of the float 22. 23 is a support located in the chamber 4 on which is journaled the lever 24, whose end 24 is located in the recess 25, formed by the offset 26 of the plunger 5, when 6, 1923.. Serial No. 498,654.

said plunger is raised. The other end of lever 24 contacts with the stein 27 of the flush valve.

The inlet water pipe 28 is connected to the nipple 29 held irnily against the proieetien of the casing by means of itsk head 30 and nut 31. The head 30 has the valve seat for the valve 33, which valve is n crine. ly rept open by the engagement of its stein 34 with the cross bar 35 forming an integral part ofthe casing. rlenfiporarily detaching the fiushonieter for repairs will release the valve 33 and the water pressure will instantly seat the same and thus effeetually shut off the water.

The inlet valve 33 being normally open while the flushcmeter is attached to the inlet pipe 28, the compartment 3 will always be filled with water. Depressing the plunger- 5, Figure 2, will actuate the lever 24 to open the flush and relief valves, and at the same time carry the end 24a of the lever out of the recess and against the side of the plunger, forcibly holding said plunger in its depressed position through the force of the water acting against the flush valve 6 engaging the opposite end of the lever 24.

Opening the flush and relief valves will cause the bulk of the water to flow into the chamber 4 and from thence into the extension 36. ln the meantime, a smaller quantity of water is flowing through the port 15 into the interior of the plunger 5, gradually filling the saine during the flushing operation. Depressing the `plunger 5 will alsoperrnit the float 22 to drop on to the pin 37 and uncover the air port 2O to permit the escape of air as the plunger is filling with water, and said air port will close as soon as the plunger is filled. The flow of water into the plunger is simply for the purpose of returning it to its normal position. As soon as the outward nievement of the plunger has brought its recess 25 in position to receive the end 24a of the lever 24, said end will be forced therein by the water pressure acting against the opposite end of the lever, and this pressure will also assist in returning the plunger while the flush valve and relief valves are being seated. The return of the plunger will uncover the port 38 in the partition 38a to permit the water in the plunger to empty into the extension 36, as shown in Figure 1.

Having` thus described my invention what I claim is l. A flushometer of the character described comprising a casing having three communicating chambers, a. reciprocating hollow plunger in one chamber having an air vent, a float adapted to close the vent, a Hush and relief valve in the second or valve Chamber, said relief valve operatively connected with the flush valve, a lever located in the third or tlush chamber in touch with the Hush valve and plunger so that the inward movement of the plunger will actuate the lever to open both of sai-d valves and temporarily hold the plunger inits inward position yto permit the volume of water to pass Yfrom the valve chamber into the Hush chamber, while smaller volume of water passes through the relief valve into the interior of the plunger to return the same to its normal position and close the air vent and permit the inlet water pressure to close both valves, and means whereby the water from `the plunger is discharged into the flush chamber.

2. A iushometer bil the character ldescribed comprising a casingn having a valve chamber and a flush chamber separated by a partition, flush valve having its seat located in said partition and opening into the flush chamber, a hollow reciprocating plunger, a lever pivotally supported in the flush chamber adapted to be actuated by the inward movement of the plunger to open the flush valve and also temporarily hold the plunger in its inward position, a relief valve actuated by the flush valve having its seat in said partition and a passage leading therefrom :to the interior of the plunger, an inlet pipe, said casingremovably attached thereto, a valve located between the casirngr and inlet pipe, and means whereby said valve is kept in open position by the casing So that the valve chamber will always be iilled with water from the inlet pipe.

3. A iiushometer of the character described, comprising a casing having communicating chambers, a iush valve, a relief valve connected therewith, a hollow plunger, ya head at one end having` an air vent, a float within the plunger. a support therefor, said ioat having` a movement between its support and head to close and uncover the vent, and means whereby the inward movementof the plunger actuates the valves.

4. A. Hushometer ot the character described, comprising va casing having communicating chambers containing respectively a reciprocating plunger, a flush valve, a relief valve connected therewith, and a pivoted lever, the plunger having a recess to'receive one end of the lever, and the other end of the lever adapted to act-uate the flush valve when the plunger is forced inward.
