SPECIFICATION forming part of Letters Patent No. 540,347, dated June 4, 195.
A lication filed October 1, 1894- gerial No. 524,550. (No model.)
To aZZ whom it may concern.-
Be it known that 1, WILLIAM R. BAKER, of Watertown, in the county of Jeffersomin the State of New York, have invented new and useful Improvements in Water-Closet Flushing Devices, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
My invention relates to flushing devices for Water closets, which dispense with the service box, and furnish the necessary after-wash, and the object is to provide suitable and efficient means to allow the Water to flow freely into the dash-pot during the opening of the main valve.
To this end my invention consists in the combination with a main pipe or chamber closed at one end and connected at the other end with a supply pipe, an outlet communicating with one side of the main pipe, a dashpot within the latter pipe at the 'closed end thereof,a rod carrying a piston to operate in said dash-pot, a valve on the opposite end of the rod to open and close the supply pipe, and the lever to move the rod, of a small pipe or passage connecting the base of the dash-pot with the supply pipe, or the main pipe beyond the valve seat, a cut 01f in the small pipe or passage, and means through which the latter cut off is operated by the said lever; and my invention consists in certain other combinations of parts hereinafter described and spe cifically set forth in the claims.
In the drawings hereto annexed and forming a part of this specification, Figure 1 is a top plan view of a device embodying inyinvention. Fig. 2 is a vertical longitudinal section on line a: on of Fig. 1; Fig. Stis a side elevation showing the apparatus in its normal or inoperative position; andFigA is also a side elevation of the apparatus, but showing the same in an operative position.
Referring specifically to the drawings, A represents the main pipe or cylindrical chamber extending horizontally having its right hand end closed by a cap a. On the inner side of the cap, a, preferably integral with the same, as shown, is a dash-pot or tube B, concentric with the pipe, A, but much smaller in diameter than the latter and projecting from the cap a short distance. Extending sides of the tube B. On the opposite end of said rod is secured a valve, 0, formed preferably of a leather disk of somewhat less diameter-than the interior of the pipe A.
When the piston rod is forced to the right as far as possible by the action of the coiled spring, E, bearing with one end upon the valve, 0, or a metallic washer of about the same size in contact with the leather disk, and with its other end upon a flange,f, within the supply pipe, F, the supply of water is cut ofi as the rim of the valve, 0, is then in contact with a flange or seat, 0, on the inside of the pipe. When the supply is thus cutoff, or when the piston rod is moved to the right to its fullest extent, the piston, D, is in close proximity to the cap, a, or the base of the dash-pot B. t
G is the outlet on the upper side of the pipe, A, and is connected by a pipe with the water closet or sink to be flushed. On the opposite side of the pipeA from the said outlet, is formed a bearing H, for a rock-arm I-I. Said rock arm extends toward the rod D, and being bifurcated at its free end lies on opposite sides of the rod and in a recess in a block, 6, secured to the rod by set screws. By means of a spindle, h, extending through the said bearing and rock-arm, the rod, D, is moved to the left against the action of the spring to allow the water to flow around the valve, 0, to and through the outlet G. A lever, L, on a square end portion of the spindle, operates the latter with the rock-arm as hereinafter explained. After being moved to the left a sufficient distance, the piston rod is released and allowed to return to its original or normal position by the action of the spring. If the piston, D, fits very closely and is not provided with a valve or opening, the tube, B, forming the sides of the dash-pot is perforated bya number of small holes, 5, along its length, so that the valve, O, willgradually return to its seat owing to the gradual fiow of water from the dash-pot through said holes, I), that entered when the piston was moved to the left. The flow of water may be controlled or regulated by a screw, I, which passes through the side of the cap, a, and enters a small hole 1', near the base of the dash-pot. By means of this screw the hole, 1', may be closed more or less to delay the return of the valve C to its seat as long as may be necessary in order to flush the closet or sink sufficiently. By the adjustment of the screw, I, the flow of water may be prolonged after the handle has been released, as longas required.
Now in order that the water may flow freely to the dash-pot just before or at the instant the rod, D, begins to move to the left and in fact during the greaterpart of said movement, I provide a passage from the supply pipe to the base of the dash-pot by means of a small pipe, J, extending along on one side of and parallel to the main pipe. This small pipe, J, is bent or shaped to enter and extend through the center of the cap, a, at one end, the other end entering the side of the main pipe, A, to the left of the valve 0. A cut-off in the small pipe opposite or near the cap, a, permits the flow of water through .the pipe at the proper time. The cut-off has an oscillating spindle, is, with a short arm, 70, secured to its end for turning the spindle. WVhen the cutoff is closed or in its normal position, the arm, lies in a horizontal position, as shown in Fig. 3 of the drawings, and when it is open it extends in the direction shown in Fig. 4. On the end of the arm, 70, and ,loosely pivoted thereto is a segment of a disk, it, having one side edge recessed. This part, 70, engages the operating lever K pivoted on the end of the spindle, 72, through a pin, Z, eX- tending from the side of the said lever K.
When the lever, K, is raised, the pin, Z, strikes the curved edge of the part, 70 and raises it with the arm, 70, to the position shown in Fig. 4, thus opening the cut-off in the small pipe and allowing the water to flow into the dashpot. When, however, the operating lever is raised slightly beyond the point shown, the part, 76'', drops and the spindle, is, with its arm, 70', is returned to its original position by means of the coiled spring, j, on said spindle, closing the cut-off again.
In order that the movement of the rod, D, may not take place until the small cut-off is opened to an extent, I simply pivot the lever, K, on the end of the spindle h, and key or otherwise secure a short lever, L, to the spindle, h, said lever, L, being broad and provided with projecting stops, s, s, on its free end lying on opposite sides of the lever, K, said stops being separated a greater distance than the width of the last mentioned lever. It will be apparent that by this means the spindle, h, will not be rotated until the cut-0E in the small pipe is partly, opened, and further that the said cut-off is released and closed by its spring,j, just before the end of the movement of the rod,D, to the left. v
I do not claim the device separate from the side passage or pipe in this application, as said device is set forth and claimedin a pend ing application filed June 22, 1894, Serial No. 515,324.
Having described my invention, what I claim as new, and desire to secure by Letters Patent,is
