WILLIAM U. GRIFFITHS, OF PHILADELPHIA, PENNSYLVANIA.

VALVE-OPERATING MECIIANISM FOR WATER-GLOSE'IS.

Specification of Letters Patent.

Patented July 28, 1914.

Application filed July 18, 1913. Serial No. 779,690.

To all whom it may concern Be it known that I, WILLIAM U. GRIF- rITI-Is, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful'Improvements in Valve-Operating Mechanism for Water-Closets, of which the following is a specification.

. My invention relates to improvements in valve operating mechanism for water closets, and it has for its object to provide an improved mechanism whereby a water closet hopper may; be automatically flushed.

My invention comprehends the construction and arrangement of parts as illustrated in the accompanying drawing and as .18 particularly described and pointed out in the claims. It will be understood, however, that changes in the details of construction within the scope of the claims may be made without departing from my invention;

In the drawings :-F igure 1 is a 'view showing partly in side elevation and partly in vertical longitudinal section, a construction of apparatus embodying my invention;

Fig. 2 is a view showing the fiush tank in cross section with the valve and valve operating parts therein in front elevation; and Fig. 3 is a view showing a detail of construction.

In the drawings, 1 designates a water closet hopper (the top portion only of which is shown), and 2 designates the seat therefor pivoted at 3. The seat is provided with arms 4 extending rearwardly therefrom and having their rear ends connected by a crosspiece 5 which acts as a weight to tilt the seat 2 as shown in Fig. 1. The cross-piece 5 is provided with an undercut slot 6 for a purpose to be hereinafter described.

10 designates a flush tank which is substantially rectangular in cross section, as is indicated, the width of the same being considerably greater than its thickness from front to rear. My invention, however, is not dependent upon the shapeof the tank, although it is well adapted for use in a tank of the character shown. ater enters the flush tank through pipe 10 The said tank is provided with a port or opening 11 in its bottom through which a flush pipe 12, having connection at its lower end with the hopper 1, communicates with a siphon 13. The flush pipe 12 constitutes, in fact, a con- I tinuation of one leg of the siphon 13. The

opposite end of the siphon is open at all timesas indicated at 14c.

15 designates an opening into the longer leg of the siphon (regarding the flush pipe 12 as a part of such leg) which opening is,

tends horizontally and is provided with a weight 23. Movement of the lever 21 to the right, having reference to Fig. 1 of the drawings, is limited bycontact of the lower edgeof the arm 22 with the shoulder 2 1 upon the projection 20 between the ears 7 formed by the slot therein. The upper end portlon of the lever 21 is curved, as indicated at 25, to form a cam surface by means of whichthe lever 21 and the arm 22 and weight 23 carried thereby are operated.

Said lever 21 is also provided with an arm.

26 extending from one end thereof which arm is curved downwardly as shown in Fig.2.

27 designates a lever'pivoted intermediate its ends at 28 upon a lug preferably formed upon the siphon 13. lever 27 is provided with a lateral projection 29 the end of which is adapted to engage the curved cam surface of the lever 21 when the said lever 27 is moved about its pivot so'as to lower the said projection 29. When the said lever is moved about its pivot so as to lower the end carrying the projection 29 the said projection first contacts with the curved side of the lever 21 to cause movement of the same about its pivot at 30. When the projection 29 reaches the position indicated by dotted lines at 31 in Fig. 2 of the drawings, the weight 23 causes the lever 21 to turn about its pivot at 30 to return to normal upright position. Pivotal movement of the lever 21 thus effected does not affect the valve 16 upon the lever 17. In returning the lever 27 to its normal position which it occupies inFig. 2 of the drawings, the projection 29 catches underneath the arm. 26 andlifts the lever 21 together with the lever 17, causing the latter to turn about its pivot 18 and thus open the valve 16. In returning from the dotted line position indicated at 31 to normal position, the projection 29 and the arm 26 have sliding movement with respect One end of the said to each other, the projection 29 finallypassing around the end of the said arm 26. The levers 21 and 17 then return to their normal position indicated in Fig. 1 of the drawings 5 to close the valve 16. In the meantime, however, suflicient water has passed through the valve opening 15 to start siphonic action.

For the purpose of effecting pivotal movement of the lever 27 so as to depress the projection 29, I have provided the rod 35, the upper end portion of which is bent in two places, substantially at right angles to each other, so that its extreme end portion extends downwardly into the tank and is connected with the lever 27 at a point upon the opposite side of its pivot 28 from the projection 29. The greater portion of the rod 85 is located outside of the flush tanlrlO and its lower end is provided with an enlargement or ball which is positioned within the undercut slot 6 as is illustrated in Fig. 1 of the drawing.

It will be seen that when the seat 2 is moved from the full line to the dotted line position shown in Fig. 1 of the drawing, the arms 4: and connection 5 are moved upwardly causing an upward movement of the rod 35 and by reason of the connection of the upper end thereof to the end of the lever 27 as indicated at 36 the said lever 27 is caused to move about its pivot 28 so as to carry the projection 29 downwardly underneath the arm 26. In moving to this position it causes pivotal movement ofthe lever 21 as herein- 5 before described. When the seat 2 returns from the dotted line position to the full line position shown in Fig. 2, the rod is moved downwardly by its own weight and also by reason of the connection of itslower end with the weight 5 sothat the lever 27 is caused to move in a direction to carry the projection 21 upwardly from the dotted line position shown at 31 to the full line position shown in Fig. 1 of the drawings. In doing 5 so, it lifts the levers 17 and 21 as described.

I cla1m: 1. The combination of a valve adapted to be moved to open and close the same, a pivotal support for said valve, means hav- 5() ing connection with said valve whereby the latter may be moved to open and close the same which means is movable independently of said valve, the said means having a part adapted to be engaged to effect movement of the said valve and a movable member acting automatically to engage said part to effect movement thereof for the purpose stated.

2.
