SPECIFICATION forming part of Letters Patent No. 403,926, dated May 28, 1889.
Application filed August 22, 1888. Serial No. 283,472. (No model.)
To all whom it may c0ncern:
Be it known that I, PATRICK W. DOHERTY, of the city of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Operating Mechanisms for Valves of WVater-Oloset and other Tanks of which the following is a full, clear, and exact description.
This invention relates to mechanism for operating valves of water-closet and other tanks to secure their opening and closing.
Under this invention, in substance, there is combined with an opening and closing valve, which maybe otherwise of the usual or any other suitable construction or arrangement, and a lever which is fulcruined on a suitable support or equivalent mechanism therefor and suitably adapted to be operated, preferably two levers, each separately fulcrumed and each arranged and adapted to work independently, and suitably operated to open the valve and then to leave it free to close, and both connected to and operated from a common operating mechanism, and all so that in one direction of movement of said operating mechanism the valve is opened by one of said levers and left free to close,
while at the same time the other lever is placed in position for operation on the valve to open it and in the other direction of movement of said operating mechanism,-and then by the other of said levers, and the one previously placed, as stated, in operative position, the valve again opened and left free to close, all substantially as hereinafter described.
In the drawings, forming part of this specification, Figure 1 is a longitudinal vertical section of a water-tank and its discharge-pipe and a side elevation of the valve closed and mechanism of this invention to secure an opening of the valve on both movements of the operating-lever and to allow the valve after each opening to close. The valve is also shown, in dotted lines, closed. Fig. 2 is a horizontal section, line 2 2, Fig. 1. Fig. 3 is a viewin detail of modifications hereinafter explained.
In the drawings, A is a tank.
B is a discharge-pipe leading from the bot tom of the tank.
C is a valve for opening and closing the discharge-pipe at the tank and at one side, 0 hinged to a suitable stationary support and seat, 0 and D is a lever having a fulcrum, E, of a stationary support, F, of the tank, and at one end, D suitably connected by a chain and pull (not shown) or otherwise, (not shown,) as well known, so as thereby to be moved in one direction, and at its other end, D weighted at G, or otherwise suitably adapted, and as well known, so as thereby to be moved in the other and opposite direction, and on a release of the power or force applied to its end D to move it and all and otherwise, except as to the features of this invention, as well known in water-tank systems of dwelling-houses, buildings, &c., or otherwise suitably, and therefore needing no more particular description herein.
H is an upright or vertical arm or extension of the valve 0, and, as shown, constituting the overflow-pipe of the tank, opening (not shown) at the upper end, H to the waterspace of the tank and at its lower end (not shown) having communication through the thickness of the valve with the dischargepipe B, and all in itself, neither as a whole, nor as to its separate parts, forming any part of this invention.
J and J 2 are two arm projections on opposite sides of the valve 0 and its extension II, and in different horizontal planes, one above the other.
K is a horizontal valve-lever, which is above and has its fulcrum on a horizontal extension of the casing 0 making the valveseat 0 and at its opposite end and in the normal position of the lever projects under and has its upper edge in contact with the under side of the arm projection J of the valve.
L is a chain or otherline, of flexible or suitable character, and at one and its lower end connected to said valve-lever K between its fulcrum and its bearing on the valve-arm J, as above stated, and at its other and upper end connected to the end portion, D of the operatin g-lever D. This chain L, in its normal as also sion H, and in the swing of the angular valvelever M on its fulcrum M the upper and outer end of its arm M the arm the nearer to the arm projection J 2 of the valve moves through i the vertical plane of a block, J which is attached by set-screw to and thus made capable of being adjusted lengthwise on the arm projection J 2 of the valve.
The block J attached, as stated, extends downwardly and presents a vertical workingface, a, at one side and a non-working face, I), at its other side, to the arm M of the angular valve-lever M, as will hereinafter appear, The opposite arm, M of the angular valve-lever is weighted, as at M, and it is connected to the lower end of a c hain,N,or,other line, of flexible or suitable character, which at its upper end is connected to the operating end portion, D of theoperating-lever D, and in the closed position of valve and the normal positions of operating and angular valve-levers D M is taht.
The angular valve-lever M in its normal position has both arins vertical, and its arm to work on the abutment-block of valve-extension H is then at one side of and opposite to the non-working face I) of the block, as will hereinafter more fully appe'ar.
gular Y&1Y6.-1 6V6I consists of a hinged ,or swinging toe-piece, O, which has a shoulder, d, in 'position to abut against an opposed shoulder, f, of the lever-arm, and is provided with a bent spring, 9, one end secured to the lever and at its other andfree end resting on the toe-piece, and all so that the toe in its normal position rests by its shoulder d against the shoulder f of the lever, and on the swing of the angular lever in one and a direction toward and to bring the toe into abutment against the working face .a of the abutmentiblock J of the valve-extension H, said toe hearing against block thereby swings the valve on its hinge C and opens it, until by the continued swing of valve and angular 1evers the. toe and said abutmentrblock are made to escape from each other, leaving the valve free to close and the angular lever to continue its swing'on its fulcrum in the same .of the abutment-block J 3 of the valve-extention,yields thereto and passes under the end of the abutment-block, all without eficct on provided.
the valve, and finally comes to its normal position, in which position it is out of contact with and situated in relation to the non-working face I) of said abutment-block, as before explained.
An arrangement of valve-levers K M and an application thereof to a valve, in combination with an operating-lever common and connected to both, allas has been described, secures from the movement of the operatinglever in each direction an opening and a close of the valve, and the opening of valve in such case, is positively accomplished and the closing is secured from the weight of the valve, the valve being left free to close after each opening. By this means two separate discharges of water from the WZLtGIE-tftllk are secured in one complete operation of the opcrating-lever; and in order that the second discharge shall be theg-reater in quantity, thus giving the afterwashj as it is termed, to the bowl of a water-closet in connection with the discharge -pipe of the tank, the first discharge given thereto being the preliminary wash, as it is termed, the valvelevers and the parts .of the valve on which each lever works, as has been described, and all otherwise, are arranged and applied together, so that the valve is opened to the greater distance in the operation thereon of the angular valve-lever. In the operation of each valve-lever ,on the valve the'chain connecting it to operating-lever is taut, and the chain connecting the other and the nonworking valverlever is slack or loose. The valvelever K, in working on the valve to open :it, escapes from the valve projection J; when, or
1 about when, the operating-lever has reached The working end of the arm M of the anthe limit of its movement in the direction to operate said lever, and on the followingopen.
D D -for the operating-lever D, in each direction of movement thereof, are preferably A hinged or pivoted toe-piece, J Fig. 3, may be provided for the abutment-block J of the angular valve-leverfand also for the valve-arm J and valve-lever K, workingon said arm, and if the abutment-block J has such a toe-piece the toe-piece of the angular valve-lever may be either dispensed with or may be used with it. Again, the valve-arm J and valve-lever Kmay each or either one have a toe. iece, as described.
