BENJAMIN GETTY oAMrBnLL, or OAKLAND, oA ir RNIAQ OPERATING ANn CONTROLLING MEANS FonvALvEs.

T all whom it may concern:

Be it known that I, BENJAMIN GETTY- I CAMPBELL, a citizen of the United States,

residing at Oakland, in the county of Ala media and State of California, have invented certain new and useful Improvements in Operating and Controlling Means for Valves,

of which the following is a specification.

The present invention relates to improvements in operating means for valves, and

more particularly to a structure designed to be employed in connection with flushing valves, whereby a measured quantity of water is supplied on each operation of the valve.

The invention has for its principal obj ects to provide a structure which is capable" of operation without great efiort; is provided with means whereby the valve after being opened is retained in an open position for a predetermined period; and one provided with a fluid controlled timing apparatus which will operate at a determinable period to release the means for. retaining the valve in open position, thereby permitting the same to close. I V

With the above mentioned and other objects'in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being under- I stood that various changes in the form, proportion,*size and minor detailsof construction'within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of advantagesof the inventlon. V

To more fully comprehend the invention,"

reference should be had to the accompany ing sheet of drawing disclosing the preferred 2 form, and in which- Figure 1 is a view part in elevation and part in section with my invention attached to a suitable flushing valve, disclosing the toggle frame, the connection therebetween and the handle, the catch, and the pivotally mounted fluid containing receptacle; Fig. 2 is a side elevation, disclosing more fully the supporting standard, and the pivotal points for certain of the members extended therefrom. l

Referring more particularly to the figures of the drawing, wherein like numerals of reference designate corresponding parts throughout the several views1 indicates a Specification of Letters Patent.

between which is controlled by the valve 1,

prov ded with the stem 5 which projects.

through the-upper surface of the casing 1 andis provided on its upper end with an outwardly fianged plate6' provided on its upper surface with' the rib 7. A coiled spring 7. interposed between the underside" of the flanged plate 6 andthecasing 1, normally retains the valve 4 in a closed or seated position.

Extending upwardly from one side of the r upper surface of the casing 1 is a'supporting arm or standard 8,:carrying at its'upper end a horizontally disposed shaft 9",' to which are pivotally mounted the ends of arms 10 and 11, which are pivotally connected at their lower ends, as at 1'2 and 13, to the upper ends of arms 1i and 15, whichare in turn pivotally connected at their lower ends to' the upstanding rib 7 the structure forming a substantially diamondshaped toggle jointed frame; I

Pi'votally connected to the pivot points and 13are the ends of the

respective arms

16 and 17 which are pivotallyconnected at their opposite ends to the respective arms 18 and '12 projecting in diametrically opposite dlrections from the handle head portion 20 from'which projects the operating handle or lever 21', the head portion being pivotally mounted on a shaft 22 extending outwardl from the support 8 directly below the shaft 9; .It".wi1l be apparent from the-above description that on the downward movement" of the operating handle the pivot points 12 and '13 will be drawn inwardly toward each other, forcing the :lower ends ofthe arms 1& and 15 downwardly, which in turn force the valve stem 5 downwardly to open the valve 4 against the tension of' the spring 7,

and on the upward movement of the lever 21 by the spring, the respective parts will assume the positions as shown in the drawings;

Pivotally mounted on a stu'd 23' projecting outwardly from the support 8 below theshaft 22, is the lower end'of a substantially T-shaped trip lever 2t, provided with a catch 25, adapted when'theo-perating handle or lever 21 is in its downward positionto engage a shoulder 26 formed on a boss 27 adapted to pivot about the shaft 22, and

which is secured in any suitable manner, as

bythe screw 28, to the head 20. The upper end of the trip lever 24 is formed with,

alined oppositely extending

arms

29 and 30, the arm 29 carrying an adjustable weight 31 which causes the trip lever to normally maintain the catch 25 in contact with the surface of the boss 27 and in a position to engage the shoulder 26, and the arm 30 carries at its end a roller 32, with which is adapted to contact a releasing device hereinafter described.

.Pivotally mounted as at 33, on the shaft 9, slightly to-one side of its longitudinal center, is a receptacle 34 formed at its opposite ends with the

respective compartments

35 and 36 connected by a contracted channel 37 controlled by a valve 38. The chambers are adapted to contain a suitable fluid of heavy specific gravity, preferably mercury, which is admitted thereto through the filling opening 39 and the fluid passing from one compartment to the other through the channel 37 will retain the receptacle'in an inclined position'in either direction.

Extending upwardly from the handle or lever 21 is an arm 40, provided adjacent its upper end with spaced horizontally disposed

fingers

41 and 42 which when the handle is operated alternately engage a lug 43, projecting from the end of the receptacle The parts being assembled and in the position as disclosed in the drawings, the device operates in the followin manner:On pushing the handle or lever 21 downwardly,

the arms 18 and 19 through their connections will draw the pivot points 12 and 13 together, forcing the plate 6 downwardly, compressing the spring 7 and unseating the Valve 4. Simultaneously with this operation the catch 25, owing to the rotation of the boss 27, will engage the seat 26 and-retain the lever or handle 21 in its depressed position, and the valve 4 open. The finger 41 on the downward movement of the handle will engage the lug 43, and move the

receptacles

35 and 36 to a slightly inclined position in an op osite direction to that shown in the drawings, which will permit the mercury to pass from compartment 35 through the bore 37 to the compartment 36; the weight of the mercury collecting in compartment 36 will cause the same to tilt downwardly and contact with the roller 32; the weight of the mercury being greater than the weight 31, the same will be lifted and the catch 25 will be withdrawn. from the shoulder 26 which will permit the spring 7' to close the valve 4, and through the various links and arms raise the lever or handle On the upward movement of the handle the finger 42 will contact with the underside of the lug 43 and raise the receptacle 34 to a horizontal position, which will permit the mercury to fiow from the compartment 36 to compartment 35, and the receptacle being pivoted to one side of its-lon itudinal cente'r. as in the drawings. will tilt toward the compartment 35, on the mercury in both compartments becoming level, and will assume the position as in Fig. 1, when the ap paratus will be in a position to operate as before described.

It will be apparent from the above description that I have provided an eiiicient valve timing mechanism which is capable of being attached to any valve, one which is simple in its operation and may be con structed at little cost.
