ELEvAToR.

SPECIFICATION forming part of Letters Patent No. 410,181, dated September 3, 1889.

Original application filed November 22, 1887, Serial No. 255,857. Divided and this application filed March 9, 1888. Serial No. 266,653. (No model.)

T all whom it 'may concern.:

Be it known that I, CHARLES E. ONGLEY, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Elevators, fully described and represented in the following specification and the' accompanying drawings, forming a part of the same.

1o This invention relates to a mechanism for operating the main valve or other mechanism which controls the movements of an elevator, which is especially adapted for use in connection with a system of electrical connections for operating the same, such as or similar to that shown in my prior application for Letters Patent filed November 22, 1887, Serial -No. 255,857, of which application the present is a division. The mechanism constituting the 2o present invention may, however, be operated otherwise than electrically.

The invention consists, primarily, in what I -terrn an auxiliary-valve apparatus, by which the elevator-controlling mechanism is operated in the ordinary working of the elevator, but which is so constructed and organized as to permit the main valve or other controlling, mechanism tobe operated by other means in case of an emergency.

3o 4In the accompanying drawings, Figure l is a diagrammatic View illustrating an organization of the apparatus embodying the present invention. Fig. l2 is an enlarged elevation of what I term the auxiliary-Valve ap- 3 5 paratus, by which the main valve is moved in one direction; and Fig. 3 is a sectional view of the same.

Referring to said drawings, it is to be understood that B represents an elevator-car, O a hydraulic cylinder or other motor by which the car is raised, and D the hoisting-cable, all of which parts are organized in the usual and well-known manner.

E represents the mechanism for controlling the movements of the elevator, which, in the case shown, is the main or induction and exhaust valve of the cylinder O, and is of any suitable construction to allow the Water to be admitted to the cylinder to cause the car to ascend when the valve is in one position, to allow the water to escape from the cylinder to permit the car to descend when the valve is reversed, and to close both the induction and exhaust to stop the car when the valve isin an intermediate or mid` position. Such cylinders and valves are in common use, and their construction is well known. I have not, therefore, deemed it necessary to illustrate or describe the same in detail. It is to be understood, however, that the cylinder C may, 6o

if preferred, be arranged vertically instead of horizontally,^and may be providedwith the well-known circulating-pi pe, ormaybe amotor of any of the forms common'in elevators. The mechanism for controlling the movements of the elevator is therefore the main valve or other mechanism which controls the Vmovements of the elevator-motor, and will auxiliary-valve mechanisms H O, whichare 8o operated, preferably, by electroniotors under the control of the conductor in the car. i .AS the auxiliary-valve mechanisms H O are connected bythe pipes G G with the valve-operating cylinder F2, these mechanisms may be placed in any convenient position in any portion of the building, either near to or remote from the main'valve of the elevator.

The auxiliary-valve mechanisms H\O are alike in construction and operation, and have 9o for convenience a common water-supply, oneV apparatus controlling the pipe G and the other the pipe G. These auxiliary-valve apparatuses are controlled in the case shown by electromotors I J ,which are energized through. electric circuits, including suitable battery power and appropriate circuit-closers, located upon the car and at the different landings, all as shown and described in my prior application beforereferred to. f H

The construction and operation of the auxiliary-valve mechanisms H O will now be described. As these two mechanisms are exact duplicates, a description of one will apply7 to both.

Referring to Figs. 2 and 3, it is to be understood that ct is a valve-cylinder containing two valve-seats c2, formed upon the ends of a bushing l), having perforations c and two heads b b2, which are securely fastened in the cylinder. The auxiliary induction and exhaust valves CZ e are connected by a valverod f, to'which a spiral spring f is applied to hold the valve CZ against its seat and the valve e away from its seat. The valve-cylinder is enlarged at one end-to form a cylinder a', in which is itted a piston g, which is attached to the valve-rod f. Communicating with the cylinder a is a pipe 7i, which is controlled by a valve h3, termed for convenience a primary valve, the rod 7b4 of which is adj ustably connected by the nuts j* to a lever j, carrying at its free end an armature j', held within the magnetic field of the clectromotor J by means of the suspension-rod f, having a nut js, by which the position of the lever j is adjusted.

The water-supply pipe 7c communicates with the valve-cylinder d, and also with the pipe h, as shown, and the induction and exhaust pipes G G communicate with the cylinders d of the respective valve mechanisms between the heads b b2 of the bushing Z). Each of the cylinders a is provided with a waste-pipe Z, which communicates with the space between the valve e and piston f, and each of the pipes 7i is provided with a small open wastepipe m, which communicates with the pipe between the piston g and valve h3.

The operation is as follows: The valves d are normally held against their seats c2 and the valves e away from the seats by the springs f, and also by the pressure of the water in the supply-pipe k, thereby preventing any water from entering either of the pipes G or G to create a greater pressure upon one side of the piston F and operate the main valve and at the same time leaving the pipes G G open to allow the water to flow out of either end of the cylinder F2, and thus permit the piston F to be moved in either direction. As soon,however, as either one of the motors I or J is energized by the closing of the electric circuit through said motor, its armature will be attracted, thus raising the lever j and primary or motor valve h3 and allowing water from the pipe 7L to enter the cylinder a and act upon the piston g, and as the area of the piston g exceeds that of the auxiliary induction-valve CZ the valve e will be moved to its seat and the valve CZ away from its seat and allow the wat-er to enter by the valve d and pass through the openings c to the pipe G or G', as the case may be, and to the cylinder F2, causing the piston F to be moved and operate the main valve to cause the car to ascend or descend. As soon as the circuit through the motor is broken the motor will be de-energized and its armature released. The "weight of the lever j, aided by the pressure of the water in the pipe 7L, will at once close the primary valve h3, thereby removing the pressure from the piston g. The water between the valve h3 and the piston g will then gradually escape through the pipe fm, thereby allowing the sprin g f to restore the auxiliary induction and exhaust valves t-o their normal position. By closing the circuit through the other motor the same operation will take place in the other auxiliary-valve apparatus, thereby admitting water to the other end of the cylinder F2 to act upon the opposite side of the piston F and move the main valve in the opposite direction, and this being continued the main vvalve will be revefsed and the car caused tomove in the opposite direction; or if it is desired to simply stop the car the circuit will be broken as soon as the main. valv'e arrives in its mid-position, and the car will then remain at rest. As the piston F is moved in either direction by the admission of water to one end of the cylinder F2, the Water in the other end of the cylinder will iind an unobstructed escape through the pipe G or G, as the case may be, and past the auxiliary exhaust-valve e to the waste-pipe Z. The waste-pipes m are, as will be observed, always open for the escape of water from the cylinder ct; but these pipes being of small size as compared with the pipes 7i, the water will not escape with vsutlicient rapidity to prevent the pistons g from operating properly.

The rods h4 of the primary. valves h3 are preferably provided with sliding joints, as shown in Fig. 3, so as to permit those valves to accommodate themselves more readily to their seats.

Although the valves h3 are herein illustrated as provided with means by which they are operated electrically, ,it is to be understood, as before stated, ,that these valves may be operated through other suitable connections with the car, if preferred.

In addition to the appliances for controlling the ordinary working movements of the elevator through the auxiliary-valve apparatuses which have been described, it is desirable that means should be provided by which, in case of an accident or in case the auxiliaryvalve apparatuses should for any reason become ineffective, the conductor can operate the main Valve or other mechanism which controls the movement of the car directly. For this purpose the rod F is provided with the usual rack, which is engaged by a pinion upon a shaft 2l, having a pulley 20,-around which passes a hand-rope 22, which extends around pulleys located at the top and bottom of the shaft and passes through the carin the usual manner.

It has already been stated that the auxiliary induction and exhaust valves d e are TOC) IIO

normally maintained in such position as to Y open the pipes GG' to allow the water to iiow out of the cylinder from both sides of the piston F', and thus permit the piston to be moved in either direction. From this it results that in case the auxiliary-valve mechanisms fail to act the main valve will not be locked by the water in the cylinder F2, but will be free to be operated by the hand-rope 22 or other mechanical connection. This hand-rope will not be used in the ordinary working of the elevator; but in case of any emergency, as before stated, the conductor can, by means of this hand-rope, operate the main valve, and thus have mechanical control of the movements of the elevator, as in the old way.

The hand-rope 22 may be provided with the usual buttons located near the top and bottom of the shaft, and which will engage with the car and operate the main valve to stop the car before it reaches the limit of its movement in either direct-ion. rope is herein illustrated as the simplest and, all things considered, the most desirable mechanical appliance forcontrolli'ng the Valve, in connection with the electrical appliances herein described; but it 4is to be understood that any of the other forms of mechanical connections by which the conductor in the car is enabled to control the main valve may be applied and used in place of the simple handrope shown, and are to be regarded in this connection as equivalents of said rope and included Within the term rope.

The form of motor C, for operating the elevator, which is herein shown, has been 4selected merely for the purpose of illustrating one application of the invention. Any other suitable form of motor may of course be employed.
