FLUSH- SPECIFICATION forming part of Letters Patent No. 746,044, dated December 8, 1903.
Application' ined April 21, 190s.
To @ZZ whom it may concern.: p
Be it known that I, LOUIE T. DERY, a citizen of the United States, residing at Montpelier, in the county of Stutsman and State of North Dakota, have invented certain new and useful Improvements in Flush-Valves, of
l canse the automatic seating of the valve after actuation from the normal position thereofr For a full description of the invention and the meritsthereof and also to acqnireaknowledge of the details of construction of the means for effecting'the result reference is to be had to the following description and drawings hereto attached. v.
While the essential and characteristic features of theinvention are susceptible of modi- Iication, still the preferred embodiment of the invention is illustrated in theaccompan'ying drawings, in whicht Figure lis a vertical sectional-view through Fig. 2 is a detailside elevation of the piston and valve shown in working relation. '4 Fig. 3 is a horizontal sectional view through the valve-casing and the`A inner chamber.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. ,Y
In carrying outthe invention the casing 1` is provided with an inlet-opening 2 at the npper portion thereof, to which the service-pipe `will be connected when 'the device is` placed in operative position. Within the casing 1 is disposed a chamber 3, this chamber being rigidly fixed within the casing l in any suitable manner. Au outlet-'opening 2a, disposed at the lower portionof the casing, is adapted to receive the pipe leading to the closet-bowl in a manner which will be readily apparent. A
Serial No. 153,625. (1510y model.)
piston 9 ismovably mounted within the inner chamber 3, and this piston is the actuator means for operating a valve 5, by which the outlet-opening leading fromA the casing 1 is normally closed. The piston is provided with a piston-rod 6, which is formed witha tubular portion 8a at the lower part thereof. The tubular portion 8a of the piston-rod 6 receives the valve-stem 7, andthe said stem is providedgwith a head 10a. The piston is held normally at the lower end of thechamber 3 bya coil-spring 24, which is disposed so as to surround the piston-rod, normally exerting a pressure against the upper side of the piston-head, which causes same to rest at the lower portion of the chamber until actuated from this position and causes valve 5 to rest upon its seat by means of the end of the tubular stem 8L resting on head 10a. A lever 20 of ordinary type is pivoted to the casing 1, and this lever is connected at one end to the piston-rod 6, and from the other end thereof extends a chain'25. The valve 5 is normally held seated by the pressure of the piston-rod against the head 10, formed upon the,y valve-stem 7. When the lever 20 is pulled downward by the chain 25, the piston 9 is moved toward the upper portion of the inner chamber 3, and when the said piston 9 has approximately reached its limit of movement toward the upper end of the said chamber a lower clamping-ring 10, whicliserves ,to-clamp the packing of the piston upon one side, engages 'with the head l()a and the valve 5 is raised from its seat 17. The valve being lifted from its seat, the water which has been drawn within the outer casing rushes through the outlet 22L and into the pipe connected thereto down to the closet-bowl in the usual manner. Upward movement of the piston by its tendency to create a vacuum within the chamber causes a suction which draws the water coming.r in from the service-pipe through the inlet 2 within the said inner chamber through the passage-way 23, which leads into the side of the latter and also through the passage-way 18. krlhe passageway 23 is located at the lower portion of the inner chamber 3. When the chain 25 is released, the spring 24 forces the piston 9 to IOO the lower part of the chamber and the water which has been drawn within the chamber is forced through the passage-Way 23 into the outer casing 1 and from the outer casing through the outlet 2, giving a continuous flow ofwater to the closet-bowl. The outletpassage 23 is of such a size that the return of the piston 9 to its normal position when the chain is released is by an approximately slow movement, being retarded, of course, by the Water within the said inner chamber. It is proposed to so regulate the outflow of water from the inner chamber 3 through the passage-way 23 that the return movement of the piston 9, to cause seating of the valve 5, may
be also regulated. This is accomplished by providing means for increasing or decreasing the size of the passageway 23, whereby the amount of water flowing into the casing 1 through the said passageway may be regulated, so as to regulate the flow of water through the casing 1 and outlet 2a. The means before mentioned consist. of a pin 13, which is threaded into the side of the casing and is regulated by means of a finger-piece 14. An indicating-plate 15, provided with suitable data, such as numerals or the like, indicates the position of the pin 13 with relation to the passage-Way 23. By means of this plate 15 the position of the pin 13 is determined, and thus the size of the passage-way 23 is increased or decreased to permit the water within the inner chamber to escape slowly or the reverse. The valve 5 when off of its seat moves in a recess 27 upon the closing-cap et at the lower end Y of the inner chamber 3, and thus is not affected by the :rush of water through the outlet 2a.
Having thus described the invention, what is claimed as new is 1. In a fiush-valve mechanism, the combination with a casing, an inner chamber disposed Within the casing, outlet and inlet means provided upon the casing, a valve disposed in the casing adjacent the inner chamber and normally closing the outlet means, a stem extended from the valve and passing within the inner chamber, a piston mounted within theinner chamber and provided with a hollowstem, said hollow stem of the piston receiving the portion of the valve-stem Within the inner chamber, means for actuating the piston to cause unseating of the valve, and spring means for normally holding the piston in such a position as to cause the valve to remain normally seated.
2. In a ilush-valve mechanism, the combination with a casing provided with inlet and outlet means, an inner chamber, a valve seated so as to normally close the outlet of the casing, a piston disposed within the inner chamber for cooperation with the said valve at ascertained points in its movement, and a recess disposed adjacent the valve and adapted to receive the same when actuated from its normal position.
In testimony whereof l afiix my signature in presence ot' two witnesses.
