WILLIAM J. CALLOW, OF TORONTO, ONTARIO, CANADA.
FLUSH-TAN K CONTROL.
Application filed May 2, 1917.
70 01% whom it may concern: Be it known that I, WILLIAM JonN CAL- Low, a sub ect of the King'of Great Britain.
of York. Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Flush-Tank Controls, described in the following specification and illustrated in the accompanying drawings, that form part of the same.
he principal objects of the invention are to eliminate the undesirable prolonged noise made by the inflowing Water to flush tanks following the flushing, and to obviate the unsatisfactory conditions of float valve controls.
A further object is to devise a simple compact and. effective mechanism which will maintain a full flow of water to the tank until it is filled and will then out 01f instantaneously.
The principal feature of the invention consists in the novel construction and ar rangement of parts whereby an instantaneously closing valve is maintained full open for the maximum period and upon release closes quickly without causins? a water hammer, the valve being retarded in closing by a Water brake applied to the valve spindle. In the accompanying drawings, Figure 1 perspective viewof my improved con- In the practical application of the present invention the Water supply pipe 1 extends into the tank and supports the self closing valve 2 which is of a Well known type. valve is arranged in a horizontal position with the spindle 3 extending toward the front wall 4 of thetank.
Secured upon the end of the valve spindle is an extension'member 5 provided with a circular flange 6 Which' is formed with a ratchet notch 7. The outer end 8 of the ex tension member 5 is drilled transversely and a rod "9 is inserted therethrough and secured by the set screw 10. The rod 9 extends downwardly into the tank and has a sheet metal vane 11 secured to its lower end. The V shape and forms a brake to engage the Water in the tank and retard the closing movement of the spindle against too rapid action, thereby preventing water hammer.
12 is a metal frame secured to the inner side of the front Wall of the tank having a Specification of Letters Patent.
Patented Jan. 14, 1919. Serial No. 165,922.
sleeve 13 which extends through the wall and is secured at the outer side by a nut 14. The sleeve 13 is arranged in axial alinement with the spindle of the valve 2.
15 is a. spindle journaled in the sleeve l3 having a suitable operating handle lli st cured to its outer end and upon its inner end is secured a cam plate 17 which is adapt ed on rotation to engage the lever 18 which is pivotally secured to the portion 19 of the frame 12.
The lever 18 is connected at its outer end 19 to a rod 2i) for operating the release valve, which is not shown. and is guided in its swinging movement by the slotted guide 21 on the frame 12.
The cam plate 17 is provided with a pair of pins 22 and 23 which project inwardly into the tank and extend each side of the rake rod 9 and are so arranged as to en gage the said rod upon the rotation of the cam plate to turn the spindle of the valve 2 coincident with the raising of the lever 18 to open the flush valve.
. pawl 24 is pivotally mounted on the stud 25 formed pawl formed with a hooked outer end 26 Which rides upon the flange 3 carried on the spindle of the valve 2 and upon the rotation of the said spindle to open the valve 2 the hook end 26 drops into the notch 7 and holds the valve full open.
A rod 27 is secured to the outer end of the pawl 24 and carries a ball float 28 at its outer end.
In the operation of this device, upon the turning of the handle 16, the spindle 15 is rotated to open the inlet valve 2 through the connections described and the pawl 24 drops into the notch in the flange 6 and holds the valve open. Coincidently with the opening of the valve 2, the lever 18 is raised to open the release valve. Upon the rotation of the spindle to open the valves the rod 9 is swung to a substantially horizontal position.
The water flows into the tank at full flow until it engages and lifts the float 28 thereby lifting the pawl to release the flange 6 Whereupon the valve 2 immediately closes.
As the rod 9 and brake member 11 are rigidly connected to the valve spindle,'the vane is forced downwardly in the Water and checks the valve 2 against closing too rapidly.
A device such as described is extremely on the frame 12 and said
