ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 291,835, dated January 8, 1884.

Application filed April 30, 1883. (No model.)

To (all whom it may concern Be it known that we, LoUIs BEROUD and EMMA XVALsI-I, citizens of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Elevators; and we do declarethe following tobe afull, clear, and exact description of the invention, such as will enable others skilled in the art to which 1 o it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in elevators for use in coal-shafts,factories, hotels, residences, or other places where such things are desirable or necessary.

It consists in the means whereby the ear is automatically arrested in its fall when released by breakage or otherwise from the hoisting mechanism, and in the mechanism for preventing the car being carried above a certain point,

and in other improvements, all of which will 2 5 be hereinafter described and claimed.

In the drawings, Figure 1 is an edge view of the shaft, having the elevator-car and releasing mechanism therein 5 and Fig. 2 is a side view of the guy-rod and elevator, and Fig. 8 is a detail plan view of the compress ing-ring, and Fig. l is a detail view, all of which will be described. V V I The elevator-car A is provided on its opposite sides with guides or ways a a,which slide 3 5 on the guy-rods Z) Z) and steady the motion of the car. On the sides of the car, about midway between the guides a and the sides thereof, we fix the metallic staples or loops a, which extend in a line parallel with the guy-rods b b, as shown.

The pawls c are pivoted on the pins c,which are arranged on opposite sides of the guy-rods in a horizontal line about with the lower end of the staples or loops a, and their points 0 4 5 are serrated, as shown in Fig. 1, and adapted to be forced into the guy-rods and lock the elevator-car in position when released from the hoisting mechanism, as will be described. The outer ends, 0, of these pawls c are passed through the staples a, as shown. On the side of the car, above the pawls c, we fix one end of a spring, d, the other end of which bears on the pawl c and assists in the automatic oper ation of the device.

Projected from the side of the car, near its upper end, are short pins' d, which are arranged in a vertical line about with the outer side of the staples a, as shown. These pins serve to guide the connecting-rods 0, hereinafter described, in their descent, and secure a uniform action of the pawls 0. The connecting-rods care swiveled at their lower ends to the outer ends of the pawls c, and extend above the top of the elevatorcar, and are connected to the bailf, as shown in Fig. 2. This bail is composed of the base-rods f and the side rods, f the latter converging at their upper ends and being made fast to the headpiecef", which is provided with eye f ",to which the chain 9 is fastened.

When our elevator is to be used in coalshafts,we preferably'make it open at each end and secure rails a a" on the bottom for the coal-truck a to roll on. In order to secure for the truck a steady position within the car, we

journal the rod a on the inner side of the,ele

vator. This rod has its ends turned as shown, to provide the cams ahwhich bear against the side of the coal-truck, as shown, and brace the same in place. Instead of turning the ends of the rod as is preferred and shown, disks might be eccentrically secured thereon to providev the cams a". On the rod to we secure a stop, a which strikes against the side of the elevator-car and prevents the rod to being thrown too far back in the operation of releasing the coal-truck. ing the cams a bear against the sides of the coal-truck, the rod a might be made long enough, so that the cams a might be turned down on opposite ends of the coal-truck.

I11 hoisting the elevator it will be seen that the bail, connecting-rods, pawl, &c., are inthe position shown in full lines, Fig. 2. Should the hoisting mechanism break or the elevatorcar be otherwise detached, the weight of the bail f and rods 6 will carry the pawls into engagement with the guy-rods and stop the descent of the elevator. Should the break occur in the connecting-rods c, the spring (2 will act to force the pawls into engagement with the guy-rods, the bottom of the staples or loops IVhere so desired, instead ofhava serving in each case as a stop to limit the downward movement of the outer ends of the pawl, as will be understood on reference to the drawings.

It is often desirable in elevators to provide means to prevent the car being carried above a certain point, either by the carelessness of the operator or mishaps in the machinery. To this end we form or secure a stop, If, on guyrod 11', as shown, and arrange between the ear and the hoisting mechanism a connection, H, constructed as hereinafter described. This connection is composed of the bars h h, preferably curved as shown. These bars are pivoted together near their upper ends and are connected to the hoisting-chain 17, as shown. In the bar h, near its lower end, we form the longitudinally-elongated opening h through which the lower end of the bar h passes and works, as shown, and will be hereinafter de scribed. To the lower end of the bar h we pivot the rod h, which is passed through the chain 9 and a suitable opening formed through the lower end of bar h, and is provided with a vertical opening, through which the spring key h" is passed. This spring-key is preferably made I- shaped,with its wing 71f adapted to be engaged by the stop I) and drawn out of the opening through the rod h, and permit the bars h h to be separated and release the elevator-car when the said bars are compressed by the ring I, hereinafter described. Between the bars h h, we arrange the spring h", which tends to force the bars apart into about the position shown in Fig. 1, when they are not compressed by the ring I. The ring I extends over the elevator-shaft, and it and the stop If are arranged in proper relative position to the stopping-point, so that the trip b will drive the key it out, and the ring I will then compress the bars h h, so that the rod 715 will ecome detached from the lower end of the bar It and the elevator-car will be released. By the devices described it will be seen we have provided an automatically-detachable connection between the elevator-car and the hoisting mechanism, and means for automatically checking the car when released from. the hoisting mechanism. In this device the weight of the car is sustained by the bail or frame f, connecting-rods e, and the pawls c, the latter being pivoted to the car, as hereinbefore described. \Vhen the bail becomes detached, its entire weight falls instantly and directly upon the ends of and gives instantaneous action to the pawls. The car is locked at once before it acquires any momentum byits descent. It will be also seen that the connecting device H forms a link between the hoisting-chain '5 and the car-bail. When the latter is disconnected, the device H remains secured to the end of the hoisting-chain. It is readily adjusted and attached to the car-bail.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. In an elevator cage or car, the carryingframe and locking device, consisting of the hoisting-bail arranged above the cage, the series of depending rods having their upper ends pivoted to the hoisting-bail and their lower ends extended downward along the sides of cage, and pivoted to the arms of the safetydogs, and the safety-dogs pivoted on gudgeons fixed to the cage, and supporting the weight of thelatter, substantially as and for the purposes set forth;

2. The combination of the elevator-car, the hoisting mechanism, the guy-rods, the pawls c, connecting-rods a, bail], and pins (1', fixed on the side of the elevatonear inposition to guide the descent of the connecting-rods 6, substantially as and for the purposes set forth.

8. The combination of an open-ended elevator-car, a truck, a, and a rod, a, journaled in the sides of the car and provided on its opposite ends with cams a adapted to operate substantially as and for the purposes set forth.

4. In anelevator, the combination of the elevator-car, the connection H, consisting of bars h h, cross-bar hi, and key h, and connecting the elevator-car and the hoisting mechanism, the guy-rod provided with trip b", and the compression-ring I, all arranged and operating substantially as set forth.

5. In an elevator, the combination,with the hoisting-chain and the bail supporting the elevator-car, of an interposed detaching mechanism, H, having the hoisting-chain secured to its upper end and the bail of the hoisting-car secured to its lower end, and means whereby the mechanism H may be operated and the carbail detached therefrom, substantially as set forth.

In testimony whereof we aiiix our signatures in presence of two witnesses.
