METAL CLIP FOR BINDING ROPE ENDS AND FOR USE IN ROPE-SPLICING;

To all whom it may concern:

Be it known that 1, JOHN J. A. MILLER,

a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented a new and useful Metal Clip for Binding Rope Ends and for Use in Rope-Splicing, of which the following is a specification.

My invention relates to an improved metal clip for use in rope splicing and also for securing the loose strands of hemp and to splicings and in binding the strands of rope ends. I attain these objects by the mechanism illustrated and described in the accompanying drawings, in which,

Figure 1 is a view of a piece of ordinary hemp rope, showing the strands thereof bound together adjacent to one end by the improved clip. Fig. 2 is a similar viewof the opposite side of the rope, showing the manner of securing the ends or points of the clip prongs to the said rope. Fig. 3 is a sectlonal view on the line 3-3 of F 1g. 1.

v Fig. 1 is a plan view of one of the clipsbefore the same has been bent, the clip being stamped from sheet metal. Fig. 5 is a perspective view of the clip showing the prongs thereof partially bent for convenience of at tachment to the rope. Fig. 6 i's-a front View showing the clip bent into the position it occupies when clamped upon a rope. Fig. is a plan View of a clip, the prongs of which are circular in cross section. And Fig. 8 is a View showing the application of the clip in splicing rope.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates the rope encircling or band portion of a clip embodying my invention, the ends of which terminate in pointed prongs 2 and 3. The prongs 2 and 3 are each straight on one edge and inclined on the other edge, so that when the clip is bent into circular form the inclined edges rest one against the other, as shown in Fig. 2, thus maintaining a uniform width of band. The

Specification of Letters Patent. Application filed November 1'7, 1913. Serial No. 801,515.

clips are made of different lengths for different sizes of ropes,the full length of a clip for a given size rope being sulficient to permit the clip to be wrapped around the rope, its ends overlapping or passing each other side by side, enough to allow one prong to extend to the center of one strand of the rope, and the opposite prong to extend past mm the next strand of the rope,

long enough to extend entirely through and.

beyond the surface of the rope when theclip is placed thereon, so that it may be bent to lap over onto one or both of the prongs. 2 and 3 when the clips are clamped upon the rope. The clip thus comprises a band,'the' ends of which are in the form of prongs,

and'a prong extending at right angles to the band, the improved clip being designed to be used for binding the loose strands of rope ends and. thustake theplace, offthe usualwrapping ,whichis employed for preventing the strands, from becoming untwisted. i

The band 1 of the clip is clamped upon the rope with suflicient force to embedit slightly into the surface of the rope, so that it will not form an obstruction in handling or in operation when passing over a sheave wheel. In order that the point of the prong 7 1, which overlaps one of the prongs 2 or 3,'may not project beyond the surface of the rope and thus form an obstruction, an indentation 5 may be formed in one or both of the prongs 2 and 3, near their pointed ends, which will receive the pointed end of the prong 4, and thus permit it to lie flush with the surface of the ropes, as will be fully understood by reference to the accompanying drawings. The clip shown in Figs. 1 to 6 inclusive, may be stamped from sheet metal of suitable character, but in Fig. 7 is illustrated a clip 6, the prongs of which are round in cross section. In other respects, the clip 6 is identical with that shown in the other figures.

i 7, l and 13, where the knots occur, the improved clips are secured in the manner In Fig. 8 is illustrated a View il1ustrat-. ing the application ofthe clipin rope splic-r ing. In splicing the ends of a rope together in the usual way, the strands of each of the; ends are untivisted for a suitable length, and the untwisted portions are placed together, crotch to crotch, and a strand from one end is tied with a strand from the other end toform a knot 7, the letter B indicating where the two crotches unite, the rope illustrated; being a three strand rope. Then a strand: 8 of one rope end X is untwisted for suitable distance, and a strand 9from the other rope end Y is wound or twisted into the space previously occupied by the strand 8, and the strands 8 and 9 are then formed into-a knot 10 at thepoint A. In the same manner, the remaining strand 11 of the rope end Y is untwisted fOl a suitable distance, and the remaining strand 12 of the rope end X'is twisted into the space'previously occupied by the strand 11, and the strands 11 and 12 are tied to form a knot 13 at the point C. In the usual manner of splicing, the tied ends at A, B and-O would be secured by tuckingthem under other strands of the'ropes, a process which is not only difficult, but requires considerable skill, especiallyin cases of wirerope splicing, and it is to eliminate this difiicult feature that my improved clip is employed. At the points before described, the clips being shown only at B and C, and being omitted at A, so that the knot may be clearly-seen. These clips prevent the knots from becoming untied, and untwisting of the strands is prevented by securing a clip on each side of the knotsecuring clip, as-shown at'the points Band C. After the clips have-been secured, the ends from which the knots are tied, are cut prising a metal strip, the opposite edges of which are cut oil at an inclination to form with the straight edge a pointed prong, one of saidprongs having a transverse indentation, and a pointed prong extending at right angles from said strip, said strip being adapted to be bent to encircle a rope, its pointed ends passing each other and bent at-an angle and embedded in the said rope, and the right angled prong extending throughthe rope, its pointed end being bent and resting in the said indentation.

2. The combination with a rope, of a strand binding clip therefor, comprising a pliable metal strip, the opposite edges of which are cut oil at an inclination to form pointed prongs, said strip being bent to encircle the rope, its inclined edges adjoining and its pointed ends passing each other, and being'bent at an angle and embedded in the rope, and a pointed prong extending at right angles to the strip, said prong being passedthro-ugh the rope, its pointed end being bent to overlap one of the prongs of the strip.

Intestimony whereof I aliiX my signature in presence of two witnesses.
