VISE FOR CLAMPING THE END PORTIONS OF CABLES OR ROPES 2 Sheets-Sheet 2 3mm [l R. Grange 1" m WJW Patented Jan. 6, 1948 UNITED STATES PATENT OFFICE VISE FOR CLAMPING THE END PORTIONS OF CABLES OR ROPES The present invention relates to a vise for clamping the end portions of a cable or rope in such a manner that a wire rope socket may be slipped over such portion.

The main object of the invention is the design of an apparatus serving the above purpose and suitable for difierent sizes of cables or ropes.

Another object of the invention is the design of a clamping device of simple, sturdy and inexpensive construction which can be operated by a person without special training and experience.

With these objects and others as will become apparent from the following disclosure, the invention resides in the novelty of features, combination and arrangement of parts as described in the following description and illustrated in the accompanying drawing forming part of this application and in which:

Figure 1 is a top plan view of the preferred embodiment of my invention in inoperative or open position;

Figure 2 is an enlarged top plan view in operative or clamping position;

Figure 3 is a still more enlarged longitudinal, central and vertical section on line 3-3 of Figure 2;

Figure 4 is an enlarged transverse, vertical section on line 4-4 of Figure 1;

Figure 5 is an enlarged transverse, vertical section on line 5-5 of Figure 2.

In the drawing in which like reference characters designate like or similar parts, numeral 2 denotes one of four legs which are of angular cross section and converge upwardly. At an intermediate point these legs are connected by a brace 3 which takes the form of a plate and may also serve as a shelf for tools, supplies and the coiled portion of a wire rope the end portion of which is to be clamped in the device being described.

The plate may be connected to the less by any suitable means preferably welding. Another plate 4 is supported by the upper ends of the legs and connected thereto by welding or other- 4 wise. Upon opposite marginal end portions of the top side of this plate strips 5 are secured by bolts 6. Angle irons I having their horizontal flanges extending toward one another are mounted upon plate 4 between said strips to function as guides for a structure to be described. The angle irons extend considerably beyond one side of plate 4 and are provided throughout their lengths with guide strips 8 of a width of flanges to which they are secured. The narrow vertical edges of these strips are in contact with the lower portion of the inner side of the vertical flanges and their bottom faces rest on the inner portion of the horizontal flanges. A pair of narrow guide flanges 9 are each vertically spaced from and above the guide strips and fixed to the upper inner marginal portion of the vertical main flange and extend throughout that portion of the angle irons which overhangs the table described and for a short distance over that portion of the angle irons resting on the table.

A slide it! (Figures 1-4) of suitable material, preferably iron, is shaped for cooperation with the guide structure described and consists of a top portion slidable between the guide flanges 9 and a bottom portion having lugs ii that slide beween the guide strips 8 and flanges 9. To the outer or righthand (Figures 1-3) side of this slide are affixed by welding or otherwise two parallel spaced horizontally disposed plates l2, [3; the upper plate I 2 slides beneath the guide flanges 9 while the bottom plate l3 slides upon the horizontal flanges of angle irons l and between the guide strips 8. These plates have on their free front edge angular cut-outs I4 of about 60 for a purpose which will become clear as the descriotion proceeds.

Between the movable plates described is disposed a stationary plate l5 which has a similar cut-out l6 facing in a direction opposite that of the cut-outs in the first described plates. The rear end of plate [5 has a flange l1 whereby it is welded to a rod l8 mounted in the vertical flanges of the angle irons. Figure 5 shows the outlines of the flange i1 partly in dotted lines.

To eiiect the motion of the slide the following mechanism is provided. The slide has in the center of its upper portion an aperture which is lined by a bearing ring IS in which the reduced portion of a screw 20 is journaled. On the rear side of the slide a nut M is threaded on the reduced portion which carries on the front side of the slide a washer 22 and nut 23. On the left- 5 hand end of the table and angle irons is an abutment 24 which has a U-shaped (Figures 1, 2) boss 25 on its inner side. The boss and abutment have a threaded hole for the screw which carries upon its outer end a hand wheel 26 with a handle 21 extending outwardly and at right angles to the plane of the wheel.

In order to operate the device described the hand wheel is turned in the proper direction to retract the slide and the plates carried thereby about one-third of the width of the horizontal until the cut-outs in the three plates have a cross sectional area large enough for the passage of the cable or rope C, the end of which is to be fitted with a wire rope socket. The hand wheel is then turned in the opposite direction until the rope end is clamped in the cut-outs and between the plates. Since the strands of the rope or cable are loosely pressed together, the wire rope socket may he slipped with ease over the rope end protruding above the plates.

The foregoing description describes and the accompanying drawing illustrates a preferred embodiment of my invention. However, it is to be understood that the specific details of this embodiment are not limitations, but more examples of my invention, :and that in adapting the same to meet different conditions, various changes in form, proportion, and minor details of construction may be resorted to without departing from the spirit and scope of the invention as defined in the appended claims.

What I claim and desire to secure by Letters Patent is:

1. In a vise, an elongated supporting frame having a plate member disposed therein and fixed thereto and provided with a notch at one end thereof, forming a fixed vise jaw, a movable vise jaw slidably disposed in the supporting frame,

guide means for slidably supporting the movable vise jaw in the frame and relatively to the fixed vise jaw, said movable vise jaw including a plurality of spaced plates forming a space therebetween in which the fixed jaw is receivable and between which said fixed jaw is closely engaged, said plates of the movable jaw having notches in an end thereof, opposite to the notched end of the fixed jaw and combining therewith to form a substantially diamond shaped opening as the movable jaw is moved toward a projected position and into telescopic engagement with the fixed jaw and manually actuated means for moving the movable jaw toward and away from said fixed jaw, said supporting frame including side rails between which the movable jaw is slidably disposed and which are provided with inwardly extending horizontal portions provided with upstanding guide strips for slidably supporting the bottom plate of the movable jaw and on the upper side of which the fixed jaw is supported, and said side rails having upstanding longitudinal flanges provided with inwardly extending guide strips, between which and the upper side of said fixed jaw, the upper plate of the movable jaw is slidably supported.

2. In a vise, an elongated supporting frame having a plate member disposed therein and fixed thereto and provided with a notch at one end thereof, forming a fixed vise jaw, a movable vise jaw slidably disposed in the supporting frame, guide means for slidably supporting the movable vise jaw in the frame and relatively to the fixed vise jaw, said movable vise jaw including a plurality of spaced plates forming a space therebetween in which the fixed jaw is receivable and between which said fixed jaw is closely engaged, said plates of the movable jaw having notches in an end thereof, opposite to the notched end of the fixed jaw and combining therewith to form a substantially diamond shaped opening as the movable jaw is moved toward a projected position and into telescopic engagement with the fixed jaw and manually actuated means for moving the movable jaw toward and away from said fixed jaw, said supporting frame including side rails between which the movable jaw is slidably disposed and which are provided with inwardly extending horizontal portions provided with upstanding guide stripsfor slidably supporting the bottom plate of the movable jaw and on the upper side of which the fixed jaw is supported, and said side rails having upstanding longitudinal flanges provided with inwardly extending guide strips, between which and the upper side of said fixed jaw, the upper plate of the movable jaw is slidably supported, and said movable jaw having an end wall, remote .to the fixed jaw and provided with extensions at the ends thereof slidably disposed between said guide strips.
