ELEVATOR CONTROLLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 519,119, dated May 1, 1894:.

Application filed November 22,1893- Serial No. 491,626. (No model.)

in Elevator Controlling Devices, of which the following is a full, clear, and exact description, reference being hadto the accompany- 1ng drawings,which form a part of this specification.

My invention has for its object to provide ready means in the car and connected with the elevator operating mechanism, which will be readily controlled by the operator.

In the drawingsr-Figurel is a front ele vation partially in sect-ion of a portion of the elevator operating mechanism and the elevator controlling mechanism. Fig. 2 is a modified form of the same. Fig. 3 is a detail view of portion of Fig. 2. Fig. 4 is an enlarged front elevation of a portion of the car showing the lever and friction devices for operating the cable.

Fig. 13 is adiagram showing the course of the cables with relat-lon to the arrangement of friction devices shown in Figs. 11 and 12. Fig. 14. is a sectional view on the line cc, Fig. 5. p

T is the elevator shaft; T the elevator car; 1. the lifting cable which passes round the sheaves, t, 1?, around the fixed pulley't and then around the sheave i upon the operating piston i t is the valve controlling the admission of the fluid to the operating cylinder 15*.

t is the inlet from the fluid source to the valve, and t the pipe leading from the valve to the'cylinder.

B B are the operating cables which pass up the shaft T beside the car T and around the fixed sheave b at the top of the shaft T. On the outside of the car is placed the lever 0 shown in detail in Figs. 4:, 5, 6 and 7. This lever is pivoted at D, and connected at its pivot point with the car, and on this same pivot is placed the wheel F. At the other end of the lever O is placed the wheel E. The wheel F is on the outside of the cable B, and the wheel E is on the outside of the ca ble B 0 is slotted at c, and a block H has a bearing adapted to slide in said slot. To this sliding block is pinned the sheave G. This sheave is between the two wheels E and F, and, as may be clearly seen in the detail figures, is flanged. The position of these sheaves is such that the cables B and B are free from the sheave G when the sheave is in its central position. To the sliding block H is attached the arm N bent, as shown in Figs. 5 and 7, the bent portion of arm N passing through a slot in the frame of the elevator car, and having the plate 1, projecting from which plate Z are the handles K and L. Through this same slot and through a slot in the plate Z, a handle I, attached to the lever 0, passes. The cables B and B may be connected with the operating mechanism in various ways. I have shown two. In Fig. 1,1 have shown it connected to a lever B, having on eachside of its fulcrum point springs 'r, r. This lever is connected with the piston of the piston valve S, which has the inlet port 0', and ports leading to the cylinder M, one on each side of the piston m. In said cylinderM this pistonm is connected with the valve t. By this arrangement the main valve 15 is operated by the piston in cylinder M, which is controlled by the piston valve S, thereby relieving the operating cables. B and B of the work of operating valve 2?. In place of connecting the cables B and B with the auxiliary valve in the manner just described, the cables B and B can be connected, as shown in Fig. 2, in which case the cables pass around the sheave A, upon the shaft of which is a pinion, a, which works in the rack,-a', on the valve stom or of the main valve i a To prevent the valve i from oper- Between these twowheels the lever ating too quickly, I attach'to the valve a piston contained in the cylinder 0. The upper side and under side of this cylinder are connected by pipe P, containing a cock Q. This cock opens in'both directions, and in consequence of the movement of the valve, requiring the contents of one side of this cylinder to be forced to the other, the greatest speed at which the valve can be operated can be nicely adjusted by adjusting the cock Q. In order to operate the mechanism with either one of these connections, suppose the elevator to be at rest and the operator desires to cause the same to ascend; the operator grasps the handles I and L and forces the handle L toward the handle I, which moves the sheave G toward the sheave E, clamping the cable B between the sheaves G and E. After 'clamping, the handle I is moved upward in the speed desired, he relieves the handle L and allows the cable B to pass freely, when the elevator continues at that speed. If he desires to stop, he grasps the handle K with the handle I and clamps the cable B between the sheave G and the wheel F. As the cable B operates the operating mechanismin the opposite direction to the cable B then, owingto the motion of the car, the mere clamping of the cable B operates the operating mechanism to stop the supply and stop the elevator. To descend the operator grasps the handles I and L in the same manner as heretofore described, in ascending, but pushes the lever 0 downward to start the elevator, when to increase the motion or stop it he operates it as before described for stopping when ascending.

In place of the wheels E and F, blocks E and F can be attached to the lever O, as shown in Figs. 6 and 7, the cables being allowed to slide in their blocks, and if desired even the sheave G may be replaced by a block.

In Figs. 8, 9 and 10, I have shown the operating cables wound around sheaves E and F corresponding respectively to the sheaves E and F of Fig. 4. The lever C is not slotted, while a flange non the arm N has a bearing on the lever G and is adapted to slide thereupon. In this arrangement, the sheaves E and F are of course loosely journaled and the operating cables instead of touching them tangentially, passes once around each of them.

Consequently the travel of the car will cause the sheaves E and F to revolve. This arrangement permits the substitution for the large intermediate pulley G of a small friction block G. To start the car, the friction block, which is operated precisely as is the.

large intermediate sheave of Fig 4, is brought in tight contact with the flanges of the sheave E, and the lever thrown in the direction in which the operator desires to start thecar. This will draw up the cable and operate the valve. In stopping, the friction block is s n1- ply brought in contact with the revolving sheave F, thereby checking its motion and thus stopping the cable.

In Figs. 11, 12 and 13, I show two pairs of sheaves, the sheaves of each pair being mounted on a common axis. The operating cable, as Fig. 13 will show, in its downward extension passes under one sheave, E of one pair, and over one sheave F of the other palr, while on its return it passes over the remaining sheave E of the first named pair, and under the remaining sheave, F of the other pair. Obviously, the friction block cannot be located in this construction between the pairs of sheaves, owing to the crossing of the cable. Instead there are two friction blocks located respectively at opposite ends of the lever N. By bringing block, G in contact with sheave E and block G in contact with sheave F the elevator can be controlled in the manner before described. To prevent eitherfriction block from clamping more than one of the corresponding pair of pulleys, the pulleys, F. and F may be made larger than pulleys, E and F as illustrated.

The devices hereinbefore described may be modified, and still embody my invention, although the preferable constructions are those which I have described.

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