Specification of Letters Patent.

Patented Jan. re, 11ers.

To all whom it may concern Be it known that I, ALFRED F. MORENCY, citizen of the United States of America,

residing at Sturgis, in the county of St.

to reduce the velocity of the water after leaving the feed or supply pipe, thereby eliminating the usual noise incident to the flushing operation, particularly where, a

high pressure water supply is utilized.

With the above general objects in view, the invention may be defined further astconsisting of the combinations of elements embodied in the claim hereto annexed and illustrated in the drawings forming a part hereof wherein Figure 1 is a side elevation of the invention partly in section. Fig. 2 is a horizontal section taken on the line 2-2 Fig. 1.

Referring more specifically to the draw ings in which like reference numerals designate corresponding parts in each of, the views 1 represents the bottom of a flush tank of usual construction apertured as at 2 to receive a flange supply pipe 3 having its outerend connected with a suitable source of water sup ly (not shown), and the inner end thereof secured to the lower end of a ,water feed pipe 4.

- A truncated cone shaped valve seat member 5 screwed upon the upper end of the pipe 4 is provided with a central opening 6 coincident with the bore of pipe 4. This opening 6 is normally closed by a cylindrical valve 7 seating upon the edge 8 of the wall 9 surrounding said opening 6. The valve 7 has the upper portion thereof closely embraced by the contracted upper end 10 of casing 11, which in turn is secured to the outer annular wall 12 of the truncated cone shaped member 5 as by screw threaded connection 13.

As best shown in- Fig. 1, the casing 11 has anenlarged or bulged portion 14 extending both above and below the valve seat 8 forming an expansion chamber 15 for a purmember 5 is provided with a screw threaded portion 16 adapted to receive the upper end,

of a correspondingly threaded tube 17 surrounding and concentrically located with respect to the feed tube 4. The tube 17 terminates at its lower end a short distance above the bottom 1 of the flush tank, and at its upper end communicates with the expansion chamber 15 through arc-shaped peripheral-openings or slots 18 formed in the member 5,

Any suitable mechanism may be employed for operating the valve 7, but in accordance with the present embodiment of my invention the casing 15 is formed with oppositely disposed upwardly curved arms 19 and 20. The arms 19 and 20 are forked and the former arm projects considerably above the latter. A lever 21 is pivoted at one end between the forks of the arms 20 and has its other end projecting through the forks of the arm 19 and its intermediate portion projecting through the upper looped end 22 of the valve 7. A float lever 23 is pivoted intermediate its ends to the arm 19 and is connected to the end of lever 21 by means of a link 24:. It is" of course understood that the long end 25, of the float lever car- -ries a float (not shown).

With the parts in the position seen in Fig. 1, the lowering of the end 25 of the float lever 23 causes the valve 7 to rise from its seat. As the valve opens, water rushes from the feed pipe 4 through opening 6 formed in member 5 into the chamber 15, Where the force of the water is more or less dissiplated, and from this chamber passes out t rough the openings 18 down thewalls of tube 17 finally discharging into the flush than the diameter of the feed pipe 4, the

water flowing down through the tube is spread over a comparatively large area and consequently the operation of the invention is practically a noiseless one. Moreover, it will be noted that the water in the chamber 15 surrounding the valve seat drops back into the tube 17 with a pressure evenly distributed around the seat.

In practice it has been found desirable to make the tube 17 of such a size that the space between the tube and the inclosed feed pipe 4 will be somewhat greater in area than the intm'ior of the feed pipe,.but I 10 prising a coupling adapted to pass through the bottom wall of a tank and be rigidly securedthereto, a stand pipe detachably connected to and supported by said coupling, a cap threadedly engaging the upper extremity of said stand pipe and provided with an opening extending thereth'rough; the end of the walls forming said opening forming a valve seat, a second pipe embrac ing said stand pipe, threadedly engaging the said cap and terminating short of the said coupling, a cylindrical member with outstanding integral armssecured to the outer periphery of said cap'and provided with a central opening extending through the top thereof, a cylindrical plunger valve member slidably disposed within said opening and adapted to rest upon and closesaid valve seat, means pivotally secured'to' ca said integral arms adapted to actuate said valve member, said cap provided with openings for establishing communication of said second pipe with said cylindrical member.

In testimony whereof I aflix my signature in presence of two witnesses.
