JOSEPH S. PEDEN, OF JERSEY CITY, NEW JERSEY.

CABLE-G RIP.

. SPECIFICATION forming part of Letters Patent No. 506,014, dated October 3, 1893.

Application filed April 5, 1893. Serial No. 469,095. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH S. PEDEN, a citizen of the United States, residing in Jersey City, in the county of Hudson and State of New Jersey, have invented a new anduseful Improvement in Cable-Grips, of which the following is a specification. f

My invention relates especially to the construction and arrangement of grips for cable railway cars, and has for its object the prov1s1on of a double grip, the two parts whereof may be operated independentlyin an effective and simple manner; the provision of means whereby the cable will be automatioally released when the grip comes in contact with any obstacle; and also the provision of means whereby the grip may be raised up beneath the car wherewith it is employed, clear of the cable way and ground, so that the car may be run upon an ordinary track. 7

To attain the desired ends, my inven 'on consists in certain novel and useful combinations or arrangements of parts, and peculiarities of construction and operation, all of which W111 be hereinafter first fully described, and then p nted out in the claims.

II1 the accompanying drawings, Figure 1 is a P View of a car wherewith my improved cable grip is employed. Fig. 2 is a side view of, showing the grip as lowered to the cable, and engaging therewith. Fig. 3 is an end View of the car. Fig. 4 is a plan view'of the grip, the connected parts being in section at line -00 of Fig. 3. 'Fig. 5 is a side elevation, and vertical, sectional view .of the car, at line y-y of Fig. 1.

Like numerals of reference, wherever they occur,indicate corresponding parts in all the figures.

1 is the main frame, or platform of the car.

90 are cross pieces, connecting the sides of the main frame 1. 2 are standards passing downward therefrom, and acting as journals for the axles, 3, whereon are mounted the wheels, 4.

Passing downward at each side of the main frame, between the wheels, are vertical standards, 5,connected togetherat bottom bycurved cross-pieces, 6.

7 are vertical rods, passing downward from the main frame 1, to side bars, 8, whicn'pass between the vertical stan dards 5. (See Fig. 2.) i

9 are Vertical rods, passing from the-crosspieces 6 to the main frame 1.

10 are standards passing from the curve of each cross-piece 6, at the center thereof to the main frame, at 11.

12 are horizontal, inwardly projecting arms from standards 10, having vertical slide ways 13, and upwardly projecting arms 14, passing therefrom to the main frame 1.

Mounted upon the four rods 9, are movable bars, 15, having side arms 16, which pass to the vertical rods 7, being movably mounted thereon.

17 are cross bars connecting the arms 16 together, below cross-bars 16, and 18 are bars connecting said arms 16, together at their outer ends. At the center of the bars 16, are vertical bars, 19, connected together at the top by a crosspiece 20. This device formsa guide for one portion of the grip lowering and .raising mechanism. Extending upward from the center of each vertically movable side .bar18, are eyes 21, wherein are pivoted links 22. To the other extreinities'of these links are pivoted arms, 23, said arms being fulcrumed upon stays 24, in the fixed vertical bars, 5, said stays curving downward and engaging with bars, 6. The upper extremities of arms 23, are pivoted to horizontally movable yokes, 25, which engage with operating 'levers,26, pivoted at 27- upon the main frame, 1. The object of this arrangement is to providemeans whereby the grip mechanism, to

be hereinafter described, may be raised and lowered within the cable conduit or way.

28 are bars, pivoted at 29 to the uprights, 10, at each side thereof, the bars upon one side engaging with the operating levers 30 to move independently of each other, in accordance with which of two cables it is desired to grasp.

37 is a vertically movable frame, arranged to play upon the slide Ways, 13, said frame having downwardly extending bars, 38, secured thereto. These bars 38 are fixed at bottom to the lower grip jaw 39. Engaging with the frame 37 at the top, are arms, 40, pivoted at 41 to the standards, 10, and engaging at their outer extremities with operating levers, 42.

Passing through the lower jaws of the grip, are bolts,43, bearing upon their lower extremities a shoe 44, the ends whereof are turned upward, as at 45, and are provided with projections, 46. i

47 are collars fixed upon the bolts, 43, the upper grip jaws resting upon said collars, which also serve to hold the bolts 43 in place, and 52 are guide pins, extending from the shoe 44 into perforations in the grip jaw 39.

48 and 49 represent cables, and 50 and 51 supporting pulleys.

When a car provided with my improved cable grip is in the shed, or run upon a track, indepenclent of an y grip and cable-way, all the parts are raised to the position shown in Fig. 5. When run out over the cable, the lever 42, is first operated, lowering all the parts to the position shown in Fig. 2, the grip being within the cable-way, and the two upper independen tly movable jaws raised from the lower jaw, permitting the cable to run free. If it is desired to pick up the cable 49, the jaw 36 is closed down before the grip is dropped into place, said jaw occupying the position shown in Fig. 3. The grip jaw 34, is left raised, and the cable coming in contact with the overhanging outer edge of said jaw, will pass into the groove between it and the lower jaw, when said upper jaw is forced down onto the cable, and the carstarts. The vertical movement of the grip, beyond that which is acquired by dropping it as far as the lever 42 and its connections will permit, is obtained through the medium of levers 26, and their connections to the grip from either end of the car. If it be desired to pick up the cable 48, the jaw 36 is left up when the grip is dropped, and jaw 34 closed. It will thus be seen that either cable may be picked up or dropped independent of the other. When the grip is in the position shown in Fig. 3, and a cross-cable, or other obstruction comes in contact with it, the shoe 44, will be forced upward, the projection 46 thereon comingin contact with the uppergrip jaws, and forcing them up, releasing the cable 49 from the grip, thus avoiding accident. If the levers 30 and 31 were provided with bolts arranged to catch in notches in a segment, when the grip engaged the cable, such an operation as is above described could not take place, and in order to permit it, I screw-thread the upper ends of the levers 30 and 31, and apply thereto manipulating handles, 75, havingscrew-threaded perforations which engage with the levers. Just at the point of union between thelevers and manipulating handles, 75, are placed bearing segments, 76. When the gripman moves a lever 30 or 3l,he turns the handle 75, raising it clear from the segment 76, and when the grip is tightened upon the cable, he screws the handle 75 down upon the segment. This gives sufficient holding power to retain the cable in the grip; but when the shoe 44 is struck, there is power enough transmitted through the connections to a lever 30 or 31 to cause the handle 75 to slide upon the segment, releasing the grip upon the cable.

In order to overcome the difficulty heretofore experienced in carrying a cable grip around curves, I have provided means where by the cable may be released at each end of the grip, and retained in the center thereof.

To the upper jaw of the grip is secured a pin 77, said pin being arranged to enter a perforation, 78, in the lowergrip jaw. When the car reaches a curve, before it losesits momentum, the gripman eases up the cable by raising the upper jaw sufficiently to permit the cable to slip out at both ends of the grip, while still held in place in the center by the pin. As the car starts around the curve, the grip is tightened, the cable being held only at the center, as illustrated in Fig. 4. When the car reaches the straight track, the grip is raised, allowing the cable to enter the same at full length, and then the grip is tightened. In dropping the cable entirely, the upper jaw is raised to the position shown in Fig. 2, leaving room below the pin 77 for the cable to escape from between the grip jaws.

By my peculiar construction of cable grip, and mechanism for operating the same, the gripman can drop the cable instant-1y at any desired point, such for instance as in crossing another cable, and can again pick it up at any point, without the intervention of any other machinery or mechanism than that carried by the car, the use of special sheaves, &c., in the cable-way, for the purpose of raising the cable to the grip being entirely unnecessary. In case of a fire along the line whereon my invention is used, the grip may be raised entirely clear of the cable-way and track, and the car run over a hose bridge, as in the case of an ordinary horse car. If the cable which is being used should break, it may be dropped, and the second cable within the conduit picked up at once, and this may be done at any point upon the line where the car happens to be at the time, and thus there is no material delay occasioned.

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

,1. A grip for cable railway cars, having one lower jaw, and two independently movable upper jaws, substantially as shown and described.

2. In a cable grip of the character herein specified, the combination with the lower jaw,
