MECHANISM FOR OPERATING- FLUSH-TANK VALVES.

Specification of Letters Patent.

Patented Apr. 2, 1914.

Application filed December 1, 1913. Serial No. 803,973.

To all whom it may concern: Be it known that I, JOHN W. MnAKns, a

I citizen of the United States of America, re-

siding at Detroit, in the county of Wayne and, State of Michigan, have invented certain new and useful Improvements inMechanism for Operating Flush-Tank Valves, of which the following is a specification, refer ones being had therein to the accompanying drawings. I

This invention relates to mechanism for operating fiush valves for water closets and the like and to an arrangement thereof that provides for stable support of the parts, the ready assembling and dismounting thereof and positiveness of action, the mechanism being so disposed that no screws or like fastening means are used in holding the parts together.

The invention also includes means where by the oscillations of a handle in either direction results in the movement of a valve operating lever to raised or open position, the mechanism being adapted to be mounted on the inner face of the flushing tank and in a single opening therethrough whereby it is especially advantageous for use with enamel, porcelain, steel or glass tanks.

The invention consists in the matters hereinafter set forth and particularly pointed out in the appended claims.

In the drawings, Figure l is a View of a mechanism that embodies features of the invention mounted in operative position on the inner face of a tank wall, showing the parts with a valve operating "member in closed position; Fig. 2 is a similar View showing the valve operating member brought to open position by a movement of an operating handle in one direction; Fig. 3 is a similar view showing the valve operating member brought to the open position by oscillation of the handle in the opposite direc tion; Fig. 4 is a view in longitudinal section, partially broken away and in elevation of the parts when in closed position; Fig. 5 is a view in detail of a guide sleeve; Fig. 6 is a view in detail of a cam finger inserted in the guide sleeve, the latter being shown in sectionyFig. 7 is. a view in detail showing a valve operating lever in the sleeve; Fig. 8 is a view in detail showing a cam plate rock arm mounted in the sleeve; Fig. 9 is a view in detail of a modification of a cam plate; and Fig. 10 is a view showing a modification of the mechanism.

Referrin to the drawings, a hollow sleeve 1 has a reduced bearing portion 2 adapted to be secured in an opening through a wall 3 as by a suitable cap nut 4. Preferably a portion of the sleeve as at 5 is squared or otherwise arranged to enter a correspond ingly shaped portion of the opening and lock the parts from turning. A main spindle6 is rotatable in the journal portion 2 of the sleeve as by a suitable handle 7. In the preferred construction the spindle is squared or polygonal for a portion of its length and is slightly fiatted as at 8 to permit of its being bent to form a stem for the handle 7. Suitable shoulders 9 limit its movement longitudinally in one direction.

A cam plate rock arm 10 that is apertured to non-rotatably engage the outer portion of the spindle 6, and is otherwise osoillatory in the sleeve 1 has an arm 11 that extends through a guide slot 12 in the outer end of the sleeve. A locking plate 13 is swiveled on a suitable pivot pin 14 of the member 10 to loosely embrace the spindle (3. A finger pull 15 projecting beyond the end of the sleeve permits the locking plate 13 to be swung into engagement with any one of the number of transverse recesses or slots 16 in the spindle 6 so as to lock and cooperate with the shoulders 9 to lock the spindle from longitudinal movement, the point of engagement being determined by the thickness of the wall 3.

A cam finger 17 is secured in oppositely disposed slots 18 of the sleeve 1 parallel to and at an interval to the slots 12, the finger being apertured to loosely receive the spin dle and having a cam plate stop 19 at its outer extremity. Preferably the member 17 is formed or stamped of sheet material.

A valve operating member or lever 20 extends through and plays in a pair of guide slots 21 in the sleeve that lie parallel to and between the

slots

12 and 18. The lever is apertured to loosely encircle and rock on the stud 6. Its inner end adjacent the stop 19 carries a suitable lateral projection or stud 22 that extends through a cam opening in a cam plate 23. A guide slot 24 in the latter is engaged by the stop 19 so that the plate rides thereon. The arm 11 of the member 10 is pivoted or otherwise articulated to the plate 23 and is disposed in such relation to the handle 7 that movement of the latter in either direction causes a corresponding movement of the plate 23 on the finger,- lever and cam plate rock arm 10 are inserted and the spindle thrust home; the locking plate is then dropped into theadjacent notch of the spindle and the parts 7 are assembled ready for operation, the neces- 'sary connection having of course been made by the addition of the cam plate.

One feature of the device is the positive definition of movement of the several parts in their several planes by the guide slots of the sleeve so that the necessary play may be given the articulated member to insure ease of movement, there being no need of screws, cotter pins or the like to hold the parts in alinement.

Another feature is the adjustability of the device to any thickness of wall because of the engagement of the locking plate to any one of the series of notches in the spindle; the locking plate feature also permitting the withdrawal of the spindle from the sleeve and the consequent dismantling of the structure Without releasing the sleeve or detaching it from the tank wall. Conversely the parts are as readily assembled when the sleeve has once been secured into place.

The movement of the handle in either direction causes the movement of the valve operating member to raised or opened posi tion while the weight of the handle and the shape of the operating connections tends to normally hold the parts with the lever in lowered or closed position.

As shown in Fig. 9, the slot of the cam plate may be merely a straight notch 27. And, as indicated in Fig. 10, the sleeve 1 may carry a member with a cam stop or lug 28 oppositely disposed to the corresponding part of the other arrangement with. a cam plate 29 likewise reversed and adapted to reciprocate a stud 30 on the valve operating lever 31.

Obviously, changes in the details of construction may be made without departing from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts.
