To @ZZ whom it may concern:

Be it known that I, WILLIAM R. BAKER, of `Watertown, in the county of Jefferson, in the State of New York, have invented new and useful Improvements in Water-Closet Flushing Devices, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to flushing devices for water'closets or sinks, and has for its object to dispense with the tank or Servicebox and at the same time furnish the after-Wash; and the further object is to provide means for determining the length of time for the water to flow, or the quantity thereof during each operation of the device.

To this end mywinvention consists in the combination of a pipe or chamber closed at one end and connected at the other end with a supply pipe, an outletpipe communicating withone side of the. first mentioned pipe, a dash-pot formed stationary within the latter pipe at the closed end, a rod with a piston 4thereon entering the dash-pot, a valve on the 25 rod to open and close the supply pipe, and means connected to the rod to move the same longitudinally in one direction against the action of a spring; and my invention consists in certain other combinations of parts hereinat'ter described and specically set forth in the claims.

Referring to the drawings, Figure lis a side elevation of my improved flushing device. Fig. 2 is a vertical longitudinal sectional view of the same, with a side elevation of the piston-rod within the pipe; and Fig. 3 is atrans` verse section on line :uw of Fig. l, looking from left to right of the figure.

In the said drawings, A represents the pipe which is shown extending horizontally, having one end closed by a cap a, or other suitable and well known means. The cap is threaded on its inner side to engage the thread on the end of the pipe. On theinner side of this cap a, preferably integral with the same, as shown, is a dash-pot or tube, B, concentric with the pipe, A, but much smaller than the latter and projecting from the cap a short distance.

Extending centrally and longitudinally within the pipe, A, is a rod, D, which may be said rod is secured a valve, C, formed preferably of a leather disk of less diameter-than the interior of the pipe. When the pistonrod, D, is forced to the right as far` as possi- A ble by the action of the coil-spring, E, bearing with one end upon the valve, C, or a washer, of the same size in contact with the valve, and with its other end upon a tlangef within the supply pipe, F, the supply of water isA cut off as the rim of the valve, G, is then in contact' with a flange or seat, c, on the inside of the pipe. When the supply is thus cut off or when the piston rod is in this position, the piston is in close proximity to the cap 0. or to the bottom of the dash-pot B.

G is the outlet on the upper side of the pipe, A, and is connected by a pipe with the water closet or sink to be flushed. On the opposite side of the pipe, A, from the outlet, G, is formed a bearing, H', for a rock-arm, H, which extends toward the rod, D, and being bifurcated lies on each side of the rod and in a re" cess in a block, e, secured to the rod by set screws, e', e.

By means ofa spindle, h, extending through the said bearing and the rock-arm, the rod, D, may be moved to the left against the action of the spring to allow the water to tlow around the valve, C, to and through the outlet G. The spindle has a square head and may be operated by a lever thereon, as indicated in dotted lines in Fig. 3 ofthe drawings, or other suitable means. left, the piston rod is released and allowed to return to its original closed position by the action of the spring, E, alone.

It the piston, D', lits closely and is not provided with a valve or opening, the tube, B, forming the sides of the dash-pot is perforated by one or several holes, b, at different points along its length, so that the valve, C, will gradually return to its seat owing to the gradual iiow of water from the dash-pot through said holes that entered the dash-pot when the piston was moved to the left. The flow is con- After being moved to theV trolled or regulated by a screw, I, which passes through the side ofthe pipe or cap a and enters a small hole, t', at or near the base of the dash-pot. By means of this screw the hole, i, may be closed more or less todelay the return of the valve, C, to its seat, c, as long as may be necessary in order to flush the closet or sink sutliciently. By the proper adjustment of this screw, I, the flow of Water maybe prolonged after the handle is released as long as desired.

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

1. The combination in a flushing device, of -a pipe closed at one end and connected at the other end with a supply pipe, an outlet to one side of the first mentioned pipe, a dash-pot within and at the closed end of said pipe, a piston in the dash-pot, a rod connecting the piston with a valve, the seat for the valve, a spring to move the rod and valve toward its seat, perforations in the side Walls of the dashpot, at dierent points along its length and suitable means to move the rod against the action of the said spring, as set forth.

2. The combination in a flushing device, of a pipe closed at one end and connected at the other end with a supply pipe, an outlet to one side of the first mentioned pipe, a dashpot within and at the closed end of said pipe, a piston in the dash-pot, a rod connecting the piston with a valve, the seat for the valve, a spring to move the rod and valve toward its seat, perforations in the side walls ofthe dashpotat different points along its length, a screw passing through the pipe and adapted to closeV more or less the hole nearest the base of the dash-pot, and suitable means to move the rod together with the piston and valve against the action of the coil spring, as set forth.

In testimony whereof I have hereunto signed my name.

WILLIAM R. BAKER.
