CABLE-GRIP.

lECIFICATION forming part of Letters Patent No. 623,855, dated April 25, 1899. Application filed April 30, 1897. Serial No. 634,555. (No model.)

To all whom, it may concern.-

Be it known that I, LOUIS JOHN \VILDE, a citizen of the United States, and a resident of New York city, county of New York, and State of New York. have invented certain new and useful Improvements in Cable-Grips, of which the following is a specification, reference being had to the accompanying drawin gs, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to improvements in grips for cable-cars, the object of the invenrion being to provide means for preventing the cable from slipping when partially released while the car is rounding a curve, whereby the speed may be reduced for purposes of safety to the public.

The device is simple in construction and effective in operation, and, further, by the use of this invention the car can be successfully stopped and quickly stopped upon a curve when necessity demands.

The invention will be hereinafter fully described, and specifically set forth in the annexed claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a general perspective view of my improved grip. Fig. 2 is a vertical sectional elevation on the line 1 1 of Fig. 1. Fig. 3 is a similar view on the line 2 2 of Fig. 1. Fig. 4' is a sectional plan view on the line 3 3 of Fig. 1. Fig. 5 is a longitudinal section on the line a 4 of Fig. 4, and Fig. 6 is a detail sectional plan taken on the line 5 5 of Fig. 3.

As my invention is chiefly embodied in the lower portion of a grip, the drawings show the upper portion (where it attaches to the platform of a car and where the uprights en-- gage with the levers and chains) broken away.

In the practice of my invention the bedplate 0. comprises a part of the lower portion of the grip, and extending upwardly from each end of the plate a are uprights a, preferably formed integral with the bed-plate a and adapted for making connection with the platform of a car.

Engaging above the bed-plate a and around the uprights a, so as to slide up and down on said uprights, is the plate I). The plate Z) has formed integral with it the upright Z), which to work the frame 0 up and down.

engages with suitable levers and chains operated at front platform of the car and employed to move the plate b up and down. A frame 0 moves up and down on either side of the uprights a and b and has formed at the ends downwardly-proj ectin g curved arms c,which work up and down in openings a in the bedplate a.

Integral with the frame 0 and extending upwardly from it are the uprights 0 work ing between the uprights a and b and engaging with suitable levers and chains employed The ends of the frame 0 engage against and on either side of an upright or throw-out e, the lower end of-which is beveled outward on either side, as at e, and moves up and down in opening-a in bed-plate a.

At each end of the frame 0, connecting the two sections thereof, are bolts 01, which pass through slots 6 in the uprights of the throwout 6, whereby the throw-out may be moved vertically by means of the ordinary mechanism upon the car.

The cable A passes between the bed-plate a and plate I) and is gripped between them by the action of the plate I) being forced down and against the bed-plate a.

On rounding any curved section of a cableroad the cable will exert a lateral pressure upon the grip, and should it be partially released by opening the grip it will be impossible for the cable to leave the grip owing to the arms 0 of the frame a; but if in case of emergency it is desired to release the grip entirely an extreme vertical movement of the throw-out,in combination with the framework 0, will entirely release the cable.

With my grip when a car is rounding any curved section of the road 'and it is desired to lessen the speed of the car the operator releases the cable by raising the plate I), there.- by allowing the cable A to slip through the grip, the arms 0' preventing the cable A from leaving the bed-plate a and out of reach of plate 1) when operator desires to again start the car.

Should the operator desire to release the cable and throw it off entirely, he first raises the plate I) and then the frame 0, bringing the arms 0 out of the bed-plate a, and the bolts (1 of the frame 0 move up in slots 6 in throw out c until they reach the upper end of said slots to raise the throw-out. Just as soon as the arms 0 leave or are raised above the plate a the cable will leave the grip should it be necessary to stop the car while rounding a curve.

To prevent any injury to the cable when arms 0 are in action, the said armshave their inside vertical edges rounded, as at 0 (Illustrated in Fig. (3.)

The plate I) and bed-plate a are provided with grooves and (1. in which the cable A is gripped.

The grip, as can be seen from the drawings, is made double, one side being 011 the np-track and the other on the down-track.

For purpose of lightening the bed-plate a holes a, as shown by dotted lines in Fig. 5, may be made in said plate.

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

1. The combination in a grip for cable-cars, of a bed-plate, a gripping-plate adapted to securely grip the cable, a frame having arms at either end and employed to prevent the cable from slipping laterally from the bedplate, a wedge-shaped throw-out, and bolts attached to the ends of said frame, and engaging iu slots in the said throw-out, and adapted to raise the throw-out, substantially as described and set forth.

2. The combination in a grip for cable-cars, of the bed-plate, having the uprights for the purpose of making connection with platform of car; the grip-plate having the upright em ployed in conjunction with suitable levers and chains to grip and release the cable, the frame having downwardly-extended arms whose vertical inside edges are rounded, said arms adapted to enter recesses in the bedplate, said frame having uprights employed in conjunction with suitable levers and chains to operate the said arms and throw-out, movingin openings in the said bed-plate, and operated by the action of the said frame, substantially described and set forth.

3. A cable-grip comprising a stationary plate having recesses in the sides thereof and a vertically-movable plate, the said plates adapted for clamping the cable and a verlateral movement of the cable when the car.

is rounding a curve, substantially as shown and described.

4. In a cable-grip, the combination f two clamping-plates, with a wed ge-shaped throwout and a vertically-movable framework having arms extending downwardly therefrom for preventing lateral movement of the cable upon a curved section of the road, and means for operating the said parts, substantially as shown and described.

5. In a cable-grip, the com bination of a stationary plate depending from the car and a vertically-movable plate adapted to be operated from the car, and means for operating the movable plate whereby the cable can be clamped between the plates; in combination with a throw-out comprising a verticallymovable framework constituting a wedgeshaped throw-out and downward] y-extendin g arms, adapted respectively for throwing the cable and for preventing lateral movement thereof, and means for operating the said framework, substantially as shown and described.

(3. In a cable-grip, the combination with the gripping-jaws; of guides located at the end portions of said jaws independent of the latter and arranged to extend past the grippingsurfaces of said jaws, as specified.

7. In a cable-grip, cable-gripping jaws and an attachment for one of said jaws, arranged to operate independently of said jaw, the said attachment consisting of guides extending at the sides of the opposing jaw of the grip, forming normally a barrier to the outward passage of the cable from between the jaws, and means for raising and lowering the guides independently of the movement of the gripping-jaws, for the purpose set forth.

In testimony that I claim the foregoing as myinvention I have signed my name, in presence of two witnesses, this 28th day of April, 1897.

LOUIS JOHN \VILDE.
