SPECIFICATION forming part of Letters Patent No. 452,962, dated May 26, 1891.
Application filed June 1l.l 1890.
To @ZZ wiz/0m t may concern.-
Be it known that I, JOHN C. BEEKMAN, of the city of New York, in the county and State of New York, have invented a certain new and useful Improvement in Double Flush- Tanks for lVater-Closets, of which the following is a specification.
My invention relates to an improvement in double hush-tanks for water-closets, the object being to provide a float-valve and mechanism subject to the action oi". the valve by which a double flush niay be obtained by a single impulse of the operating dev ice.
A practical embodiment of my invention is represented in the accompanying drawings, in Which- Figure l is a View of the tank in longitudinal vertical section, showing the valve and other operative parts partly in section. Fig. 2 is a transverse vertical section through line of Fig. l, with certain of the parts partially broken away to more clearly illustrate other parts. Fig. 3 is a top plan view on a reduced scale, and Figs. 4t, 5, 6, and represent the operative parts in side elevation and illustrate the positions which they assume at different stages of operation.
A represents the tank divided by a crosspartition B into two compartments A A2. The partition B terminates at a point below the sides and ends of the tank A, and is provided centrally along its upper edge with a depression B for the overflow of water from one of t-he compartments into the other. Through the bottom of the coinpartmentA extends a discharge-pipe C, the same being secured water-tight to the bottom, as herein shown, by an annular flange c', which is intended to rest upon the bottom of the tank around the margin of the opening through which the pipe extends, and the lower portion of the pipe is screw-threaded and adapted to receive a nut c2, which, when forced home into contact with the bottom of the tank A, serves to tightly seal the fjoint between the flange c and the upper face of the nut c2, and at the same time hold the pipe securely i n position. The upper portion of the pipe C is provided with a flaring valve-seat c3, the face of which is preferably circular in order to tit the curved surface of a spherical valve D. Across the upper end of the discharge-pipe C sain No. 355,112. (No monti is a bar or other suitable support c4, centrally through which there is a perforation to receive the depending stem d", which serves to center the valve within its seat. An overflowpipe c5 leads from a point above the waterline down to and opens into the dischargepipe O. The spherical valve D, here shown as formed of two heinispherical shells united at their edges, is provided with an upwardlyextending operatingrod CZ, which extends upwardly through a suitable guide E at the top of the tank and between the forked ends e2 on the arin e of the operating-lever. Stops to limit the rise and fall of the operating-rod d', and hence of the valve, are located in the desired adjustment upon the operating-rod d', and are here shown as collars d2 and (Z3, provided with set-screws, as is common, to secure them in the desired positions on the rod. The operating-lever is fulcrumed upon a suitable support eg, and to the end of its "arm e* the operating-cord provided with an operating-handle e5 is secured. A stationary arm e7 projects upwardly iii a slanting direction from the tank, in the present instance from the line of the pivotal connection e5, and to its end and to the end of the arm ci ot the operating lever the ends of a spiral spring eG are secured. The tension of the spring e6 is exerted in a direction to return the operating-lever to its horizontal adjustment after it has been operated by pulling down on the handle The valve D, I am pleased to term a floatvalve, as itis intended that it shall be of such specific gravity as that when it is wholly immersed in water it will have a tendency to ioat therein; but its weight, as compared with the weight of the water which it displaces, is such that when the water-pressure shall have been removed from a portion of its surface-nas, for example, that portion below the upper margin of the valve-seat-the pressure of the water on the other portion, together with the weight of the valve, will be sufficient to hold the valve seated. VIt is evident, of course, that the valve itself need not be of less specific gravity than water, as the saine function could be secured by counterbalancing a valve, which was of greater speciic gravity than water in such a manner as to cause it to oat when wholly immersed and remain permanently seated when the Wa- IOO ter-pressure was taken off from a portion of its surface. The stop d2 is so located upon the rod cl that the upward travel of the valve will be terminated before the stem d* shall haveescaped from the guide-bar c4, and hence the valve will always be in position to return centrally to its seat. The operation of this valve D is as follows: When a pull is exerted upon the handle e5, the valve D will be lifted from its seat through the forked arm e of the operating-lever d3 and the rod d. The operating-lever, through the tension of the spring e, will be immediately returned to its normal position; but the valve D being now wholly immersed will remain lifted from its seat and floating. The water will rush from the discharge-pipe C until the compartment A has been emptied to a point so low as to no longer float the valve D, when the latter will fall again to its seat and the discharge-pipe will be closed. As the compartment A again fills with water, the valve D, being now in a position to prevent the water from gaining access nto its lower portion, will remain seated.
The second flush is under the automatic control of the valve hereinabove described, and the mechanism by which it is accomplished is constructed and arranged as follows: A discharge-pipe l'l is secured to the bottom of the compartment A2, preferably by means of an annular flange h and nut h2, engaged upon the threaded portion of the pipe below Vthe bottom in a manner quite similar to that described with respect to the dischargepipe C. The upper portion of the dischargepipe H is provided with a concave seat adapted to receive the lower portion of a spherical valve h3, and a bar 7L, extending across the upper portion of the discharge-pipe, is provided with an opening to receive the depending valve-stem 77,8, which serves to guide and center the valve in its seat. The valve h3 is also what I term a Heat-valve, in that when wholly immersed in water it will tend to float, but when the water-pressure is removed from the lower portion of its surface the pressure on the remaining part of it will be sufficient to hold it seated. As herein shown, the valve h3 is seated nearer the bottom of the compartment A2 than the valve D is to the bottom of its compartment. An operating-rod 71;l extends upwardly from the top of the valve h3 and through a suitable opening in a bracket h5, secured to the side of the tank.
Stops, shown in the present instance as collars h6 and 7i, embracing the rod h4 and provided with set-screws to hold them in the desired adjustment, are located in such positions on the rod h4 as to determine the upward movement of the valve and also the movement of a float g4, located in the compartment A', as follows: The float g"L is connected to the arm g2 of a lever fulerumed, as shown at g', to a suitable support G, secured to the partition B., The other arm g3 of the lever extends into a position to engagethe rod 7b4, and the forked end QG of the arm g3 embraces the opposite sides of said rod h* between the stops h6 and hl. A counterbalance-weight g5 is secured conveniently by means of a set-screw in the desired position upon the arm g2 to give the requisite preponderance of weight to the arm g2. A float f? is located within the compartment A2 and connected with an arm f3 of an angle-lever pivoted at its angle to a suitable support f'l and having its other arm f5 connected with a slide-valvef6 for controlling the supply of water to the tank A through a suitable supply-pipe F. The rod f', which connects the float f2 with the arm f3 of the angle-lever, is fixed to the arm f3, so as to cause the said arm to move with the rod f. The sliding valve f6 consists, in the example shown herein, of a cylindrical plug adapted to slide across the opening in the supply-pipe F, and the arm f', which is connectedwith the end of the valve, is provided with an elongated slot f7 to allow for the play of the arm as the angle-lever is rocked upon its pivot. rlhe supply-pipe F leads into the compartment A. i Y
The operation of the whole is as follows: Vhen a pull is exerted upon the handle e5, and the valve D thereby raised, as hereinbefore explained, the valve will remain suspended (see Fig. l) and the water in the compartment A will rapidly lower. As the water in the compartment A gradually-lowers, water from the compartmentAzwill flow over the partition B and through similar openings B? and B3 (see Fig. 5) in the partition Binto the compartment A,but the escape of water through the partition B will be much more rapid than the increase of water from the compartment A2 and from the now partially-opened supply pipe. The lowering of the Water in the compartment A will gradually lower the float g4t until the forked end g of the lever connected with the float engages the stop k7 on the rod h4 and produces a sufficient lift upon `the valve h3 to lift it from its seat. When lifted from its seat, the valve h3, because of its tendency to float, will remain open and the water will gradually fill it, the valve h3 having seated itself as soon as the water in the compartment A2 became so low as not to float the valve, the rise of the ioat g4 and the engagement of the forked end g6 of the lever with the stop h on the rod 77.4 having assisted to seat said valve ha in case the water in the compartment a2 had not sufficiently lowered to accomplish it. The refilling of the compartment A2 will again lift the ioatf2 and close the valve j"U as the tank H becomes completely filled and the whole will be ready for a repetition of the double flush before described. lVhat I claim as my invention is g l. The combination, with a flush-tank provided with suitable discharging-pipes, of a valve having 4a tendency to float when immersed for controlling the first discharge from the tank, and a second valve controlled by IOC IIO
the action of the irstnamed valve to effect a second discharge, the said valves having no connection with each other except through the liquid in the tank, substantially as specified.
2. The combination, with a tank provided with intercommunicating compartments and a discharge-pipe for each compartment, of a valve under hand control having a tendency to iioat when immersed for effecting a discharge from one of the compartments, and a valve in the other compartment having a tendency to float when immersed and under the immediate control of a iioat in the firstnamed compartment for effecting a second discharge, the connection between the valve for the second discharge and the float being such that the float is allowed to move through a predetermined distance before effecting an opening of the said valve, substantially as set forth.
3. The combination, with a tank provided with intercommunicating compartments, a supply-pipe for supplying Water to one of the compartments, and a dischargepipe for each compartment, of a valve under hand control having a tendency to oat when immersed for effecting a discharge from the compartment to which the supply leads, a float in said compartment having an engagement with a valve for effecting a discharge from the other compartment, and a float in said last-named compartment for controlling the supply, the said oats for operating the second discharge and the supply being separate from each other, substantially as set forth.
at. The combination, With the tank provided with compartments for the first and second discharge, the partition between the compartments being provided With openings therethrough, of a first discharge-valve and rneans for operating it byhand, a second dischargevalve in the other compartment and having its operating-rod connected with a lioat in the rst discharge-compartment by a lever, the said float being Wholly separate from the Valve and valve-operating mechanism of the first discharge and the said leverhavingafree play between stops located at a predetermined distance apart upon the second discharge operating-rod, and a supply-valve operated by a float in the compartment of the second discharge and wholly separate rfrom the dischargevalve and their operating mechanism, substantially as set forth.
