JOHN LINCOLN GISH, OF SOUTH BEND, INDIANA.

REGULATED AUTOMATIC-CLOSING VALVE.

Application filed December 16, 1908.

T 0 all whom it may concern:

Be it known that I, JOHN LINCOLN Gisi-i, a citizen of the Unit-ed States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented a new and useful Regulated Automatic- Closing Valve, of which the following is a specification.

The object of my present invention is to construct a regulated automatic closing valve in such a manner, firstly, that the fluid in the valve-casing be retained under direct pressure, until said fluid is required for flushing; secondly, that the fluid in the valve-casing be discharged in a large vol ume, under direct pressure, into a discharge pipe; thirdly, that the flushing stream after passing the outlet in the valve-casing, perform no other work or function, but that of flushing; and fourthly, after the flushing has been completed, for the regulated automatic closing valve to be closed'automatically, the apparatus be ready to repeat its work, as hereinafter described.

Figure 1, is a perspective of my improved apparatus. Flg. 2. 1s a vert1cal section thereof, with the valve K., closed. Fig. 3, is a vertical section thereof,.with the valve K., open.

In the drawings a self closing valve, of the reciprocating type is shown.

Like letters of reference, refer to like parts in the several figures.

In Fig. 1,T. T. T., is the valve-casing.

N. N. are screws, to fasten fluid-tight, the removable top T., of the valve-casing to the body or T. T., part of the valve-casing.

I., is the inlet to the valvecasing T. T. T.

0., is a discharge pipe.

S., is a spindle passing into and through the discharge pipe C.

1-1., is a handle fastened to, and operating the spindle S.

0., is an outlet from the discharge pipe G. The usual connections with the service pipe and discharge pipe are made at 1., and 0., respectively.

F., is a wheel mounted upon suitable bearings, within the valve-casing T. T. T. (in, a hollow float, attached to the wheel F., by the set-nut (Z. E., a slot in the rim or periphery of wheel F. R., an antifriction roller. 13., a projecting arm from roller It. A., a supporting arm fastened to the inside of the valve-casing T. T. T., and engag- Specification of Letters Patent.

ing the arm 13., thereby assisting in the proper alinement of the valve K.

D. D. D., is a connecting arm between the roller R, and the inside surface of the valve K.

K., is the valve seat, in the valve-casing T. T. T.

K., is the reciprocating valve, in the valve-casing T. T. T". i

Z., is the valve stem, connecting the valve K., with the angle arm S. S., by means of of a movable hearing at S. S.

a. b. 0., on the wheel F., indicate different positions, to which the float G., may be adjusted, in order to regulate a long or short flushing stream.

t., is a movable joint in the valve stem Z.

The arm D. D. D., has cleared the roller R, from the slot E., and at the same time raised the arm 13., through its bearing in the arm A. The float G., is in the position shown in Fig. 3. The wheel F., has been partly rotated upon its axis. The roller K., is in contact with periphery of wheel F.

In my invention the wheel F is operated by the float G., and the device performs its work as follows: In Fig. 2. the valve K., is in the closed position. Fluid is allowed to pass into the valve-casing T. T. T., at the inlet I. The valve K. (Fig. 2.) being closed, the valve-casing T. T. T., is filled and the fluid is retained under direct pressure, equal to the pressure in the service pipe. As the valve-casing T. T. T., is filled with fluid the float G., is held submerged. This submerged position of the float G., is accomplished by means of the roller R, engaging the slot E., forming a lock to the wheel F., and preventing the wheel F., from being rotated upon its axis. The wheel F., being held in a fixed position, and the float G., being immovably attached to the wheel F., by the set-nut (L, the float G., is therefore held in a fixed or submerged position, as the valvecasing T. T. T. is filled with fluid. .This submerged position (Gr. Fig. 2.), of the float G., remains so, until the handle II, is pulled down, thereby rotating the spindle S., upon its axis, and bringing the angle arm S. S. (Fig. 3.), into the upright position. Asthe angle arm S. S. (Fig. 8.) changes its position, a corresponding force is made to act, upon the valve stem L, which pushes upward against the valve K., causing the valve K., to be moved away from the valve seat K., thus opening the valve K.

and allowing the fluid to pass forward into the discharge pipe 0., to be discl'iarged in a large volume under direct pressure. Cooperating with the opening of the 'alve K. Fig. 3.. the arm D. D. 1).. removes the roller R. from the slot l l.. in the wheel F. thus releasing the lock to the wheel F. The valve K., being opened and the lock to the wheel F., being released simultaneously, the lifting powers of the submerged float (i., are instantly brought into action, and the float G., is changed from position. ((lr. Fig. 2.). to position (G. Fig. 3.), and during this change of position, the float G.. rotates the wheel F upon its axis, and carries the slot E, away from the roller R, and brings the rim or periphery of the wheel F, in contact with the roller 1.. thereby giving a movable contact support to the roller 11., and at the same time by means of the arm D. D. D., holds the valve K., in the open position, and presents the relation of parts as shown in Fig. 3.

The parts will remain as in Fig. 3.. until the contents of the valve-casing T. T. have been discharged, when the float G., by its own weight, will return to position (G.), and at the same time rotate the wheel F., back to position as shown in Fig. 2., and also allow the other parts to be returned to their respective positions as shown in Fig. 2., and leave the apparatus ready to repeat its work.

From the above description it will be noticed, that the fluid is retained under di rect pressure, in the valve-casing T. T. T., thus accomplishing the first object of my invention. By the opening of valve K., Fig. 3 the contents of the valve-casing T. T. T., are discharged under direct pressure in a large volume into the discharge pipe C, thus covering the second object of my invention. Since the regulating and working parts of my'device are contained within the valvecasing T. T. T., the flushing stream after passing the valve seat K., which is also the outlet to the valve-casing T. T. T., performs no other work or function, but that of flushing, thus covering the third object of my invention. After the flushing has been completed, the regulated automatic closing valve, is closed automatically. and all other parts are returned to their respective starting positions, thus covering the fourth object of my invention.
