FLUSHING-TANK.
SPECIFICATION forming part of Letters Patent No. 586,924, dated July 20, 1897.
Applicationfiled November 20, 1896. Serial No- 612,903. (No model.) 7
To all whom it may concern:
Be it known that I, JOHN C. FISHER, a citi- Zen of the United States of America, residing at Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Flushing-Tanks, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in flushing-tanks, and has for its object to provide. new and novel means for controlling the inlet or pressure Valve of the tank whereby the required amount of water will be admitted and the valve held open while the flushing processoccurs and until the tank is again filledwith a predetermined'quantity of water; further more, to obviate the hissing noise usually accompanying the operation of flushing-tanks.
The invention further aims to provide a flushing-tank and operating mechanism that will be extremely simple in its construction, being used in connection with the ordinary pressure-valve, and that will be strong, durable, effectual in its operation, and comparatively inexpensive to manufacture.
With the above and other objects in view the invention finally consists in the novel construction, combination, and arrangement of parts to be hereinafter more specifically described, and particularly pointed outin the claims.
a which- Figure 1 is a vertical sectional view of the tank, showing all-parts in position and the.
' valve closed. Fig. 2 is a vertical sectional showing a modified form of supporting the 5o float-rod.
Referring to the drawings by reference-letters, a indicates the tank, in the bottom of which is placed the pressure-valve b, to which is connected the inlet-pipe o. This valve 1) is of the ordinary construction, and the stem at thereof is slotted to receive the pivoted arm 6, provided with a screw-threaded aperture in its outer end to receive the operating or set-screw n to limit the backward movement of the sliding weight. The operating chain or cord 0 is attached to the sliding weight and passes over a pulley 19, arranged on top of the tank. On the side walls of said tank is suspended a rod (1, to which is swiveled the floatrod 1-, carrying the float 5, said rod also carrying a vertical arm 15, having a weighted portion '1), serving to hold the. arm in its vertical position, and the said aim being adapted to engage the lug on the sliding weight, as shown in Fig. 2 and as will be more fully explainedintheoperation. Anordinarysiphon w is connected to the flush-pipe y to drain the tank.
In Fig. 6 I have shown a modified form for supporting the float-rod r. In this construction a standard or socket a, is formed integral to receive an arm or roda which supports the float m, said rod being fastened and adjusted by means of a set-screw a in the standard.
The operation is as follows: lVhen the chain or cord 0 is pulled downward, it retracts the sliding weight it on its rod, and when the same reaches a point over the center or balance the weight will slide against the setscrew n, throwing the rod in the position shown in Fig. 2 of the drawings and opening the valve 1) to admit the water to the tank, and as the same becomes filled to the predetermined point the suction created in the siphon empties the tank through the flushingpipe. During the emptying of the tank the float s will descend with the water and the end-of the weighted arm 25 will pass between the guide Z and the weight and in the rear of the lug 7c, and as the tank refills through the inlet-valve, which is still open, the raising of the float by the water will operate the floatwith or screwed into the valve 1), and is adapted rod, causing the weighted arm If to engage the lug 7t and force the sliding weight forward on its track-rod and over the center or balance, when the arm will pass out of engagement with the lug and the weight will slide to the extreme forward end of the rod, thus bringing the same to the position shown in Fig. 1 and closing the inlet-valve Z) before sufiicient water has been admitted to the tank to again create the suction in the siphon.
It will be observed that by this arrangement the back pressure on the inlet-pipe will be materially decreased, in fact, almost 0bviated, by reason of the gradual closing of the inlet-valve. As the arm carried by the iloat-rod operates the sliding weight it forces the operating-rod f downward, partially closing the inlet-valve, and as the weight passes over the center of bearing on the rod it will pass gradually to the end of the same by reason of the resistance offered by the operating-chain being attached thereto, thus almost obviating the back pressure as caused by a sudden closing of the inlet-valve and eliminating to a great extent the hissing noise caused by a sudden closing of the valve and the return of the water through the inlet-pipe. 3y providing the arm I, with the weighted portion the same will be held in a practically vertical position at all times, and by securing the guide Z to the sliding weight this arm will be guided into engagement with the lug and prevented from engaging elsewhere on the weight, especiallyat the rear of same, by reason of this guide extendingpast the weight at this point, so as to receive the arm. It will also be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.
Having fully described my invention, what I claim as new, and desire to secure byLetters Patent, is
1. In a flushing-tank, the combination of the tank provided with an inlet-valve, an operating-rod connected to said valve, a sliding weight on said rod, an operating chain or cord attached to said weight, a rod carrying a float arranged in the tank, said rod carrying an arm adapted to engage the sliding weight to operate the rod and close the "alve substantially as shown and described.
2. In a flushing-tank, the combination of the inlet-valve, an operating-rod, a sliding weight on said rod, achain or cord attached thereto, a float-rod and float, a weighted arm carried by said float-rod to engage the sliding weight when the valve is open and operate same to close the valve, substantially as shown and described.
3. In a flushing-tank, a tank, a valve arranged therein, an operating rod for said valve, a sliding weight on said rod, said weight carrying a lug and guide, a float-rod carrying a float arranged in the tank, said floatrod carrying a weighted arm adapted to engage the lug of the sliding weight and operate same on its rod to close the valve, substantially as shown and described.
4. In a flushing-tank, the tank, an inletvalve, an operating-rod for said valve, asliding weight on the rod, said rod also carrying a collar and set-screw to limit the movement of said weight, a float-rod and float havinga supporting-rod, said float-rod carrying a weighted arm adapted to engage the sliding weight and operate same to close the valve, substantially as shown and described.
5.. In a flushing-tank, the tank, an inletvalve and siphon arranged therein, an oper- 'ating-rod for said valve, said rod carrying a sliding weight having the chain attached thereto, a supporting-rod carrying a fioat-rod, and float, said floatrod carrying an arm engaging the sliding weight through the raising of the float, and moving the weight to opcrate the rod and close the valve, substantially as shown and described.
In testimony whereof I atfix my signature in presence of two witnesses.
