SPECIFICATION forming part of Letters Patent No. 399,674, dated March 19, 1889.
Application filed August 13, 1888- Serial No. 282,57 2. (N0 model.)
To all whom it may concern:
Be it known that I, JAMES LAWsoN, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented a new and useful Flush- Tank for ater-Closets, of which the following is a specification, reference being had therein to the accompanying drawings, in which similar letters refer to corresponding parts. 7
Figures 1, 2, and 3 are elevations, partially in section, of my improved iiush'tank, showing the movable parts in different positions. Fig. 4c shows a modified form of valve with supply-pipe to correspond.
A is a water-tight box, constructed of any suitable material, and sufficiently elevated above the water-closet basin with which it is connected. Box A receives water from a supply-pipe, B. The discharge of water from this pipe is regulated by a valve, O, attached to a stem, D, which may be provided with one or more weights, D. The object of these weights is to regulate the weight of the valve to correspond with the pressure of the water in the supply-pipe, which is not uniform in all localities. The valve-stem is hinged to one extremity of a lever, F, provided with a suitable fulcrum, G. To the other extremity of lever F is attached a suitable chain or cord, O, of any desired length.
S is a spring made fast to box A at one extremity, the other extremity being free and in contact with lever F, as shown. This spring acts upon lever F in starting down the extremity of the lever on the opposite side of the fulcrum.
H is a float provided with an arm, I, hinged to a suitable support, J, attached to the box. Lever I is provided with a notch, K, for the reception of a corresponding lug, L, on lever F.
M is a siphon, a vertical section of which is shown in the drawings.
The operation of my improved flush-tank Fig. at.
is as follows: I'Ve will suppose box A to contain no water, and that the different parts of the mechanism are. in the relative positions shown in Fig. 1. The force of the water in pipe B raises valve 0 sufficiently to allow the water to pass slowly but continually into box A until it rises to a level shown by dotted line it x in Fig. 3. In the use of my improved device I prefer the modified form of valve with supply-pipe to correspond, as shown in The water-closet basin is flushed by pulling downward on chain or cord 0, which raises valve O. Lug L of lever F is thus brought in contact with lever I of float I-I, raising the arm and depressing the float to the position shown in Fig. 2, lug L being in notch K, and holding valve 0 suspended, as shown in the last-named figure. Float H being depressed, as just described, raises the water suddenly in box A to the extent of the amount displaced by said float, and the water rushing in from pipe 13 at the same time fills the longer arm of the siphon, through which the contents of box A are rapidly discharged into the water-closet basin below, when the different parts of the mechanism occupy the position shown in Fig. 1, lever I having released lever F and valve O resuming its original position at the discharge-opening of pipe 13.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
In a flush-tank for water-closets, a valve, O, provided with a suitable stem, a lever, F, connected with the stem of valve 0 and provided with a lug, L, iioat H, provided with a lever, I, having a support, J, for its fulcrum, the short arm of lever I being provided with a notch, K, and a discharge-siphon, M, substantially as described, and for the purpose set forth.-
JAMES LAWVSON.
