UNITED STATES LEWIS M. LANCASTER, OF PHILADELPHIA, PENNSYLVANIA.

AUTOMATIC FLUSH FOR WATER-CLOSETS.

To all whom it mag concern;

' Be it known that I, LEWIS M. LANCASTER, a citizen of the United States, residing at Philadelphia, in the county .of Philadelphia and State of Penns lvania, have invented certain new and use 111 Improvements in an Automatic Flush for WVater Closets, of which the following is a specification.

My invention relates to an improved automatic flush for water closets, an object of the invention being to provide improvements of this character, in which the inlet valve to the tank, may be located at any distance below the level of the ground, which together with a drain to empty the pipe from said valve to the tank, will absolutely prevent any possibility of water freezing in the pipes, and hence prevent the damage incident thereto.

A further ob'ect is to provide an improved construction 0 this character, in which the valve may be drawn out of the pipe to enable the insertion of a new washer on the valve, or to repair the valve in any way, without the necessity of digging up the ground.

A further object is to provide an improved construction and arrangement of parts which will compel the tank to fill when weight is upon the closet seat, and which will automatically flush the closet when the weight is off the seat.

A further object is to provide an improved construction wherein the inlet valve will serve to open the drain when the valve is closed, to empty the pipe between the valve and the tank.

With these and other objects in view the invention consists in certain novel features of construction, and combinations, and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure? is a view partly in side elevation and par y in section illustrating my improvements. Fig. 2, is a view in longitudinal section through the tank and cooperating parts. Fig. 3, is an enlar ed view in vertical section through the in ct pi e showing the inlet valve on its seat, and ig, 4, is a view in cross section on the line 4-4 of Fig. 3.

latter being suflicient to hold the seat in an inclined position as shown in Fig. 1.

5 represents a flushing tank having a suitable cover (3, and connected by a pipe 7 with the bowl 1.

The tank 5 is supplied with water by a pipe 8, which latter projects up a considerable distance into tank 5, and is provided with a perforated cap or cover 9. This inlet -pipe 8, which projects down into the ground any desired distance, far enough to prevent any possibility of freezing, is provided with a valve seat 10 normally closed by a plunger valve 11 having an ordinary washer 12 thereon. This valve '11 is provided at opposite sides with keys 13 guided in key-ways 14 into the valve casing 15, which latter forms a section of the pipe 8. The drain pipe 16 communicates with the casing 15., and is open when the valve 11 is closed, but when the latter lifts to open, it will close communication with pipe 16 and prevent any passage of the water through said pipe. The valve 11 is secured on the lower end of a rod 17, which latter extends up through pipe 8 into tank 5, and a coiled spring 18 is located in the upper end of the pipe 8 and bears downward against shoulder 19 on rod 17, to normally press the valve 11 on to its seat.

The tank 5, is provided with a vertical sleeve or housing 20, in which a vertical rod 21 is mounted, and provided at its upper end, in tank 5, with a cross rod 22. One end of end of rod 17, and the other end of the with a tubular valve stem 24, the latter providedat its lower end with the valve 25 to close against a valve seat 26 around-an outlet port 27, connecting with the flushing pipe 7. The rod 21 is disposed vertically and is provided at its lower end, with an. enlargement 28, located in the path of movement of the arm 3 on seat 2, to be moved by the seat aswill now be explained.

follows: As shown in the drawings the valve 11 is closed, the valve 25 is open, and the tank 5 and pipe 8 are empty. When weight is applied on the seat 2, the arm 3 will engage the rod' 21 and move the latter upward. This movement of rod 21, through the medium of cross rod 22, will lift the rod 17 and valve 11, and also lift valve 25 to close the port 27. When rod 17 is lifted, the

this cross rod 22 is connected to the upper cross bar 22, is connected by a spring 23,

The operation of 'my' improvements is as valve 11 will close communication between pipes 8 and 16, and the water will flow upwardthrough pipe 8 into tank 5 until it reaches the top of the tubular valve stem 25%, when the water will flow down through this valve stem 2%, and pipe 7, into the bowl 1. \Vhen the seat 2 is relieved of its weight, it will swing upward by reason of the weighted arm 2, and the rod 21 will fall, permitting the valve 25 to open and the water in tank 5 to flow through pipe 7 and flush the bowl 1. \Vhen the rod 21 is permitted to fall, the spring 18 will force valve 11 tightly on its seat 10 and shut oii" the water, and this downward movement of valve 11. will open communication from pipe 8 to pipe 16 and .drain through pipe 16 to thoroughly empty pipe 8. It is of course understood, that this pipe 16 is to be connected to the sewer in any desired way.

A great many slight changes might be made in the general form and construction of parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: I

1. In an apparatus of the character described, the combination with a flushing tank, of an inlet pipe communicating with said tank and extending down below the level of the ground, a drain pipe communicating with said inlet pipe below the level of the ground, a valve in said inlet pipe be low the drain pipe and of a size to permit its being drawn up through the inlet pipe and tank, and said valve constructed to close the drain pipe when moved to permit the water to flow to the tank, and to open said drain pipe when moved to permit the water to flow to the tank, and to open said drain pipe when moved to closed position. Y

2. In an apparatus of the character described, the combination'iwvith a flushing tank, of anvinlet pipe communicating with said tank and extending down below the level of the ground, an inlet'valve in said pipe below the ground, said valve being of v a diameter smaller than the internal diameter of the smallest part of said pipe, permitting the valve to be drawn up through the pipe, and a rod in the pipe connecting with said valve, and means for operating said rod.

3. In an apparatus of the character described, the combination with a bowl, a flushing tank and a flushing pipe connecting the tank and bowl, an inlet pipe extending down below the ground level and rojecting up into the tank, a valve in the inlet pipe below the ground level, a spring pressed rod secured to said valve and extending above the upper end of the inlet pipe in the tank, an outlet valve in the tank to close a port communicating with the flushing pipe, said valve being normally 0 en, a hinged seat on the bowl, a weighte arm on the seat, and a rod in the path of said arm and connected with the first mentioned rod, and with the valve for the flushing pipe.

4. In an apparatus of the character de-' scribed, the combination with a tank, a

bowl, a flushing pipe connecting the tank and bowl, a hinged seat on the bowl, and a weighted arm on the seatnormally holding the seat at an incline, of an inlet pipe connecting with the tank, a valve in said pipe,

a spring pressed rod secured to said'valve Y and projecting up into the tank, a valve to close communication between the flushin pipe and the tank, a tubular stem on sai valve projecting up into the tank, a sleeve in said tank, a rod movable in said sleeve and located in the path of movement of the arm on the seat, a cross rod on said last mentioned rod in the tank, connected at one end to the inlet valve rod, and a spring connecting the other end of said cross rod withthe tubular valve stem.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
