FLUSH TANK VALVE Filed Feb. l, 1939 "mami ATTO R N EYS Patented July 9, 1940 UNITED STATES PATENT OFFICE FLUSH TANK VALVE Arthur N. Asselin, Fall River, Mass. Application February 1, 1939, Serial `No. 254,093
6 claims( (c1. l19V-104) c o 3 3 of Figure l looking in the direction of the The invention relates to a oat operated valve and more especially to flush tank supply valves.
The primary object of the invention is the' provision of a valve of this character, wherein the same is controlled by a float and is held against vision of a valve of this character, wherein the action of the valve is positive and sensitive in that suiiicient power is had from the water pressure flowing into a flush tank or box to assure the perfect working of the valve and with minimum lifting action upon the float, the valve being quick closing and thus shutting off instantly theA inflow of water when the pressure thereof is at the highest peak.
A further object of the invention is the provision of a valve of this character, wherein the parts thereof are readily accessible and of a minimum number, thereby providing for easy repairs and replacement of parts and maximum` life.
A still further object of the invention is the provision vof a valve of this character, wherein the valve assembly and the oat assembly are of novel construction toassure quick action of the valve and the perfect working thereof on installation within a flush tank or box.
A still further object of the invention is the l provision of a valve of this character, which is simple in its construction, thoroughly reliable and emcient in operation, being possessed of few parts resulting in durability thereof and elimination of repairs and replacements, strong, and inexpensive to manufacture and install.
With these and other objects in View, lthe invention consists in the features of construction, combination Vand arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.
In the accompanying drawing:
Figure 1 is a vertical sectional View through the valve constructed in accordance with the invention.
Figure 2 is a top plan view thereof.
Figure 3 is a sectional view taken on the line arrows. v
Similar reference characters indicate' corresponding parts throughout the several views in the drawing.
Referring to the drawingrin detail, the valve constituting 'the present invention comprises a substantially T-shaped valve casing or shell I0 `having a water inlet passage II to which is common the inlet nipples I2 and I3, respectively, these being preferably at right angles to each other so that the valve casing or shell I0 can be mounted for theinflow of water into a high or low ush tank or box. The selected nipple I2 or I3 is united with the water supply pipe or lead and the other being closed by a plug I4, which is interchangeable to either of the said nipples. Removably fitted within the passage I I is a valve cage or sleeve I5, being held in place by a locking ring or collar I6 and with which communicates the discharge lling pipe I1 for the tank or box (not shown) and only a portion of this tube or pipe I1 being disclosed. Also communicating with the said valve cage or sleeve I5 is a refill or syphcning tube or pipe I8, for the conventional purpose of supplying water to a toilet bowl (not shown).
At the end innermost in the passage II of the cage vI5 is a valve seat I9 for a slidable valve 20 movably fitting the cage l5 and this valve controls the water from the passage Il passing to the tubes or pipes I1 and I8, being engageable with the seat I9 for shutting off the fiow of water.
Formed on the casing or shell I0 at the uppermost side are the bearings 2| and 22, respectively. The bearing 2l pivotally supports a rocking lever 23, the pivot being indicated at 24, and this lever has lthe arm 25 supporting a weight 26. The bearing 22 has pivotally connected thereto toggle linkage 21, which is also pivoted to the lever 23, the pivots being indicatedat 28 and 29, respectively. Swingable upon the pivot 24 for the lever 23 is a float arm 30 which has adjustably fitted thereto the hanger stem 3| of a float 32, being suitably weighted at 33, the adjustability of the hanger arm being had by a set screw 34 fitting the float arm 30. 'I'his arm is formed with a forked end providing spread extensions 35 and 36, respectively, each having the lateral pins 31, the one on the extension 35 being in overhanging relation to the toggle linkage 21, while the pin 31 on the extension 36 is disposed beneath this toggle linkage. The rise of the float 32 with the rise o-f the water supply Within the tank or box causes the oat arm 30 to swing counter-clockwise as viewed in Figure 1 and the pin 31 on the extension 35 of this arm actuates the toggle linkage so that the valve 20 will be shifted to shut-off or closing position, the lever 23 being operably attached to the valve 20 through the forked formation 38 in said lever and the coupling pin 39, respectively, on the valve. The weight 33 on the float 32 is for partially sinking the float within water supplied within the tank or box so that when the Water is discharged from the said tank or box this oat will drop, rocking the weighted arm 30, forcing the pin 31 on the extension 36 in the direction of the toggle linkage 27 for action thereon to cause the valve to be moved away from the seat I9 therefor to an open position permitting the water through the -passage Il and the pipe I1 to ll the tank or box.
After the water reaches a determined level, the
float rising therewith operates the arm 30 so that the pin 31 on the extension 35 will become active on the toggle linkage 2 for actuating the valve 20 moving it to a closed position and thus shutting olf water supply to the tank or box. The weight 26 on the arm 25 of the lever 23 provides positive closing action in the operation of the valve. The valve shuts off the water supply in the direction of the inflow through passage l l so that the pressure of the water aids in effecting the tight fitting of the valve to its seat. In this manner there is no pressure required on the float to keep the valve closed tight against its seat and the weight 33 on the oat enables positive opening action of the valve and the float assures power for the closing of the valve with minimum lifting power.
One of the links of the toggle linkage 21 carries a stop ill for limiting the action of the toggle linkage in one direction so that on the upward movement the links of the said toggle are stopped in horizontal alignment with each other yet not interfering with the downward breaking of the toggle linkage 21.
What is claimed is:
l. A valve of the kind described, comprising a casing having a valve for controlling a flow passage therethrough, a rocking lever operating said valve, a float arm swingingly supported relative to said casing, toggle linkagev connections between said lever and said casing, and extensions on the arm and active against the toggle linkage connections alternately at opposite sides thereof for imparting opening and closing movements to the valve. 4
