UNITED STATES PATENT OFFICE.
)JOHN DEMAREST, OF NEW YORK, N. Y., ASSIGNOR TO THE J. L. MO'IT IRON VORKS, OF SAME PLACE.
CISTERN-OVERFLOW VALVE.
SPECIFICATION forming part of Letters Patent No. 348,663, dated September 7, 1886.
Application filed July 19, 1886. Serial No.' 208,358. (No model.)
To all whom it may concern:
Be it known that I, J oHN DEMAREsT, of the city and State of New York, have invented an Improvement in Cistern-Overllow Valves, of
which the following is a specification.
Gistern-overfiow pipes have been provided with a valve at the lower end resting upon a seat at the top of the iiushing-pipe leading to the water-closet. When this pipe and valve are lifted, the water rushes into the flushingpipe, and the air is drawn in at the top of the overflow-pipe and produces a whistling noise that is very disagreeable, especially in private residences.
Efforts have been made to close the upper end of the overflow-pipe, but there is risk of the parts adhering and not acting promptly, should the water in the cistern rise above its normal level, and thereby retaining the water and preventing the same passing off by the overflow-pipe.
My invention relates to the combination, with the overflow-pipe, of a movable cap resting upon the top of the said pipe and a bellshaped float sliding upon said pipe and acting to lift the cap whenever the water rises above its normal level, and the cap is perforated at its sides to allow the free passage of water. Vhen this overliow-pipe is also provided with a valve to the flushing-pipe of the closet, the lifting-rod passes through the cap, and by its motion from time to time prevents the cap adhering to the top of the overflow-pipe.
In the drawing I have represented my improvement by a vertical section.
A represents the iiushing-pipe l thewater-closet and connected at the upper end to the cistern B. C is the-valve-seat, D, the valve at the lower end of the overflow- 40 pipe E, and Fis the rod, and G the lever to the water-closet-pull by means of which the valve is raised; but as these parts are well known I have simply shown the same to represent the manner in which my improvement is usually applied. However, if the overiiow-pipe E was a fixture, as is sometimes the case, my improvement may be applied to the same. Around the overflow-ppe Eis a bell-shaped iioat, K, of sheet metal or other 5o suitable material, open at its lower end, and
leading to having a vertical tubular guide through the float, and surrounding the overow-pipe E. A collar at L limits the downward movement of the oat K, and a collar at N limits the upward movement. Resting upon the top end of the overiiowLpipe E is the cap P, having a downward rim and perforatons at Q. In the normal position the oat K rests upon the collar L, and the cap l? rests upon and closes the upper end of the overiiow-pipe E. If, now, the water rises above its normal height in the cistern B, the float K is lifted, and it rises up below the cap P, andit comes into contact with the perforated fiange of the cap l?, and lifts the same'off the upper end of the overiiowpipe, allowing the surplus water to pass freely through the openings Q and discharge by the pipe E. Vhen the water descends in the tank, the cap l? again rests upon the top of the overdow-pipe E.
It will be apparent that the rod F, passing through the cap E, agitates the same, and prevents the cap sticking upon the top of said VoveriioW-pipe, and when the valve is raised and the overiiow pipe lifted air cannot be drawn into said overflow-pipe, because its upper end is closed with a cap.
I claim as my invention- 1. The combination,with the overflow-pipe, of a bell-float surrounding and sliding upon the upper end of said pipe and a cap resting upon the top of the overliow-pipe, and having a perforated rim, against which the float acts in lifting the cap, substantially as set forth.
2. The combination,with the overfiow-pipe,
the valve at thelower end thereof,and the valveseat, of a bell-float around the Lipper end of the overiiow-pipe and sliding thereon, a separate cap having a downward rim and openings and resting upon the upper end of the overflowpipe`, and a lifting-rod passing through the cap and acting to lift the overflow-pipe and valve, substantially as set forth.
Signed by me this 15th day of July, A. D. 1886.
JOHN DEMAREST.
