JOHN DEMAREST, OF NEW YORK, N. Y.

FLUSl-IING ClSTERNS.

SPECIFICATION forming part of Letters Patent No. 232,009, dated September 7, 1880.

Application tiled July 22, 1880. (No model.)

To all whom it may concern Be it known that I, JOHN DEMAREST, of the cityand State of New Y0rk,haveinvented an Improvement in Oisterns for Water-Closets and Urinals, of which the following is a specication.

Heretofore, where a number of water-closets or urinals are in one place, it is usual to have a long cistern for water above such closets or urinals and a service-box to each closet placed below the cistern. rIhis arrangement is eX- pensive and difcult of access when repairs are needed.

I make use of a separate cistern to each water-closet or urinal. e One service-pipe runs along the row of cisterns and supplies water to them all, there being a ball-cock and sup-V ply-pipe to one of the cisterns or to a separate cistern, so that the water will be furnished alike to all the closet-cisterns.

In each cistern there is a valve and valve seats, constructed as hereinafter set forth, and a pipe from the cistern to the closet or urinal. When the valve is raised water is allowed to iiow from the cistern to the closet, and the pipe admitting water to the cistern is simultaneously closed.

In the drawings, Figure l is a vertical section of the eistern and pipes, and Fig. 2 is a sectional elevation at right angles to Fig. 1.

The cistern a is preferably of cast-iron and ot' a size to hold the required quantity of water. In the bottom of the cistern are two openings for the screw-tubes b and c that project downwardly from the plate d, and these screwtubes receive the clamping-rings t' that secure the parts to the cistern, and they also receive the couplin ofthe pipe k, leading to the watercloset, and the pipe l,by which wateris supplied. There is a curved pipe extending from the screw-tube c up to the cylinder 7L, which is in line with the screw-tube b, and through this cylinder h the valve-stem o passes, having upon it the double valve r s.

The valve-stein is pressed down by the spring t and raised by the connecting-wire u, lever lv, and wire fw to the closet-pull. It is preferable to have the lever within the cistern and to have the wire w pass through the tube u', that rises from the bottom of the cistern toaheight greater than that of the water as it stands in the tank or cistern. Usually the valve will be kept upon the seat e on the plate d by the pressure of the spring, and in that position the water-way through c and h is open, and the water finds its way from the pipe l and rises to the same level in the cistern that it does in the cistern to which the water is supplied with a ball-cock.

Then the pull of' the water-closet is operated the valve r is lifted oli1 its seat e and the water is free to ow to the closet. At the same time the valve s closes upwardly against the lower end of the cylinder h and prevents water running into the cistern until the watercloset pull is released and the valve r closes the passage to the water-closet.

For hopper water-closets the seat may be connected with the wire fw, so that the valve will be raised sufliciently to allow water to run while the seat is depressed.

I claim as my inventionrlhe combination, with the cistern a, of the tubes l) c, cylinder 7L, double valve 1' s, stem o, and spring t, the parts being arranged and operating substantially as set forth, to open the water-way to the closet when the inlet waterway is closed, as set forth.

Signed by me this 15th day of July, A. D. 1880.

JOHN DEMAREST.
