.To aZZ whom, it may concern.-

Be it known that I, GEORGE W. HUBBARD, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of N cw York, have invented certain new and useful Improvements in Reservoir or Tank Apparatus for \Vater-Closets, of which the following specification is a full, clear, and exact description.

This invention relates more particularly to that class of apparatus in which there is a closed tank, so that the inflow of water is stopped by the accumulation of pressure therein; but certain parts thereof are not restricted to such apparatus and maybe employed in any relation to which they are or may be suited. It comprises a new or improved combination of a closed tank, a self-acting valve, especially a selfiacting float-valve, and a specially-arranged air or waste-water pipe, and certain other new or improved constructions and combinations, hereinafter particularly pointed out.

In the accompanying drawings, which form part of this specification, Figure I is a sectional elevation of a reservoir or tank apparatus for waterclosets constructed in accordance with the invention, and Fig. II a plan of one of the parts thereof.

The water tank or reservoir A is of cylindrical form, with a height many times exceed ing its diameter. It is arrangedin an upright position. It has a bottom in one piece with its sides, and it is closed at the top by a head, B, secured by bolts 1 and nuts 2 but any suitable closed tank could be employed, and so far as certain parts of the invention are concerned it is not necessary that it should be closed. This tank A is upheld by the pipe 0, which is interposed between the said tank and an enlarged base or foot, D, so as to form a conduit communicating with said tank as well as a support for upholding the same. It is connected with base or foot I) by the T-coupliug 3 and with the bottom of the tank by straight coupling 4, externally and internally threaded but any suitable connecting means could be used.

The water is introduced into the tank A through the pipe 0, which thus becomes the water-inlet pipe, and in order to avoid emptying the tank when water is drawn in other parts of the house it is preferred to extend the said pipe to the upper part of the tank A, the

extension, as shown, being formed by an additional section of a pipe, E, secured into the coupling 4. A check-valve could also be placed in the pipe 0, if desired.

The discharge-valve F, when closed, prevents the water escaping from the tank A, and when opened allows it to pass into the discharge-pipe G, for conveying it to the hopper or bowl to be flushed. A discharge-valve of any suitable construction could be used; but it is preferred to employ a valve of the special construction hereinafter set forth.

The pipe H is a combined air and wastewater pipe. It opens through the branch 5 into the outside air, through the branch 6 into the interior of the tank A, and through the branch 7 into the space below or on the discharge side of the valve F. Consequently air may pass by said pipe into the tank A, and any Water which may enter the said pipe is conveyed into the dischargepipe. The end of the branch 5 is closed by a self-acting valve, I, which, when seated, prevents the egress of air or water, so that the pressure on the tank will then accumulate until it equals that of the Water-service and stops the inflow of water. A check-valve is a self-acting valve and could be used, it being arranged to open inward; but itis preferred to secure the automatic operation of the valve by means of afloat, 8, which closes the valve when the water reaches a certain level in the tank and opens it when the water falls below that level.

The use of any suitable fioat-valvc would be within the invention; but it is preferred to employ one having the improved construction showntha-t is to say, the float 8 and the valve proper, 9, are connected by a lever, 10, which is fulcrumed in a fulcrum-piece, ll,which can be adjusted vertically, in order that the valve may rest flat on its seat 12. The seat 12 is formed of a bushing inserted into the end of the branch pipe 6, and the fulcrum-piece 11 consists of a collar which surrounds the said pipe, and is provided with a set-screw, 18, for binding it in place; but of course the valveseat need not be formed by a bushing, and other means could be employed to render the fulcrum-piece adjustable. Any leakage past the valve I is carried away by the pipe H into the discharge-pipe. The lower end of the pipe H is screwed into the bottom of the tank A and its upper end passes through the head B, a tight joint being formed between said head and the nut 14 by screwing down the nuts 2.

The head B is depressed in the middle, so as to retain any water which might leak through thejoint, and the pipe I-I drains the said depression.

The hollow casting K is secured under the bottom of the tank A by means of bolts 15 and nuts 28, the bolts being arranged in a circle at equal distances apart, so that said casting can be adjusted into different positions around a vertical axis. In order to change it from one position to another, it is removed, turned to the proper extent, and replaced with the bolts in other holes. The object of having it adj ustable in this way is to facilitate setting up by avoiding the necessity for making joints, the hole for receiving the discharge-pipe G being in the side of said casting and the adjusting of the casting bringing it into different positions relatively to the other parts of the apparatus, whose position in the room it may not be desirable to change.

In order that thepipe H may be in free communication with the interior of the casting K in all positions of the latter, the circular passage 16 is provided beneath the lower end of the pipe H, so that its relation to said pipe is not altered by shifting the casting.

The dischargevalve F is provided with a stem, 17, of iron or steel, which is fastened to the metal head 18, and is surrounded by a brass tube, 19, securely fixed thereon, and the packing 20 of said valve is confined between the said head 18 and a metal washer,21,which bears against the end of the tube 19. This valve is easily manufactured, and the brass protects the iron or steel from corrosion,works with less friction, and is more easily packed where it passes through the bottom of the casting. The seat for the discharge-valve F is made on the hollow casting, and while this is preferred it is not essential. There are also brass bushings 22 and 23 for the valve-stem 17 19. The lower bushing, 23, is extended to the level of the discharge-pipe G, so that there will be no opportunity for sediment to settle on or around the valve-stem, and thus be worked into the joint. At the bottom of the bushing 23 is a packing-ring, 24., and a metal washer, 25, which are held in place by the spiral compression-spring 2G, interposed between said washer and the collar 27 on the valve-stem.

This spring assists in drawing the valve to its the discharge-valve F is lifted, the water escapes through the hollow casting K and the discharge-pipe G.

Modifications may be made in details with out departing from the spirit of the invention, and parts of the invention may be used separately.

The conduit 0, which enters into and forms a support for the tank A, forms no part of the present invention; but the right is reserved of making a separate application for it and the combinations or apparatus of which it is an element.

I claim as my invention or discovery-- 1. The combination, with the closed tank having water inlet and discharge pipes, and provided, also, with a discharge-valve, of the air or waste-water pipe having three branches or openings, through one of which it communicates with the interior of the tank, through another with the outside atmosphere, and through the third with the discharge-pipe beyond the discharge-valve, and a self-acting valve which closes the opening into the tank, substantially as described.

2. The combination, with the closed tank having water inlet and discharge pipes, and provided, also, witha discharge-valve, of the air or waste-water pipe having three branches or openings, through one of which it communicates with the interior of the tank, through another with the outside atmosphere, and through the third with the discharge-pipe beyond the discharge-valve, and a self-acting float-valve which closes the opening into the tank, substantially as described.

3. The combination, with the tank having the discharge-opening in the bottom and provided with a discharge-valve, and a hollow casting having a side opening to receive the discharge-pipe and secured to the bottom of said tank below said discharge-opening by means which permit said casting to be adjusted about a vertical axis to present said side opening in different directions, of a wastewater or air pipe which communicates with the interior of said casting below the discharge-valve through a circular passage at the outside of said casting adjacent to'said tank, so that on adjustment of said casting there is still communication with said pipe, substantially as described.
