Qiairns. (Cl. 289-17) The following specification relates to an improved strand lacing implement for lacing bundles of strands such as insulated wires for telephone or related purposes, textile working and the like.

Numerous instances occur where it is necessary to assemble a considerable number of strands, wires and the like in compact bundles of minimum dimensions. As an example, the wire conductors for telephone switchboards and the like, are systematically tied together in bundles. This is done in small spaces seriously handicapping the operations of tying the strands together in bundles. In the case of telephone switchboards, the wires are tied together in groups for neatness, orderly arrangement, and in order to make the handling of the wires as simple as possible. Thus bundles of wires are tied together by lacing cords being knotted from one to four inches apart.

The manual operation of lacing wires and the like is a tedious operation. The operator tying these wires together by hand must exert a considerable pressure on the cord being used. This results in injury and callouses to the fingers. in fact, such work soon results in a distortion or disfiguration of the fingers.

The present invention enables one to rapidly make an improved knot at spaced intervals from a common supply, whether it be a ball or a bobbin.

One of the objects of the invention is to improve the knot itself so that it will be easily located in the desired position and rapidly fastened Without undue strain upon the hand of the workman.

A further object of the invention is to increase the amount of compression exerted upon the strands which are being knotted.

Among the objects of the invention is to enable the knot to be provided on the bundle of wires or the like even though the latter may be located so close to the surrounding surface as to prevent the ready passage of the winding cord.

A still further object of the invention is to make possible the use of a long cord of indeterminate length as contrasted to the limited length possible in the manual handling of binding cord where the knots are made bare-handedly.

The preferred form of the invention is shown by way of example in the accompanying drawings in which:

FIGURE 1 is a side view of the implement;

FIGURE'Z is an end view of the implement;

FIGURE 3 is a longitudinal vertical cross-section of the implement;

FIGURE 4 is a side view of the shell;

FIGURE 5 is an end view of the hand grip, and

FIGURE 6 is a plan view of the needle.

Briefly described, the invention consists in an implement having a bobbin carrying a lacing thread, cord or the like of indeterminate length. This is released under manual control to a book by which the cord is manipulated in tying together a bundle of strands and forming one or a succession of spaced knots without severing the cord between the knots.

The invention is part of the disclosure in the applicants pending application filed September 10, 1962, Serial No. 222,723, now US. Patent No. 3,138,394 and of which the present application is a division.

3,150,892 Patented Sept. 29, 1964 The method of lacing is carried out by providing an implement by which a supply of cord is carried, materially greater than what is possible for an operator to manipulate by hand. The handling of the cord is accomplished by means of a hook closely analogous to a knitting needle and operating much the same way. The structure includes the lacing implement 21 which is in the nature of a shuttle used in weaving to carry the thread in a bobbin. Thus the implement includes a hollow handle 22. One end or" the handle is closed by means of a cap 23, which fits over one end of the hollow handle 22.

The opposite end of the handle carries a head 24 which is in the form of a tapering cylinder. This head carries a hook 25. One side of the hollow handle 22 is provided with a grip plate or clamp 26 which serves as a brake to prevent undesired release of the cord from the bobbin.

The head 24 has a peripheral recess 27 in which is received the front end of the handle 22.

The head 24 is drilled lengthwise as shown in FIGURE 3 to receive a hook 25. The hook is held in place by means of a set screw 28.

The grip plate or clamping member 26 is a flat blade having curvature similar to that of the hollow handle. The plate is turned down at one end 29 and provided there with a central hole 39.

The hollow handle 22 has two diametrically spaced

transverse slots

31, 31 through which the end 29 of the plate 26 is passed.

A diagonal slot 32 is cut in the cylindrical wall of the hollow handle 22 from the end opposite the head. This slot ends in an angular transverse slot 33. These slots operate similarly to the slots found in the shuttle of a sewing machine and for the same purpose, namely to permit threading and withdrawal of the cord from the bobbin.

A central bolt 34 passes longitudinally through the handle 22. At its front end it carries a thrust washer 35. Beyond the thrust washer the end of the bolt 34 is screw threaded to fit Within an axial screw threaded hole 36 in the head. The opposite end of the bolt is slotted to permit it to be inserted with a screw driver.

In assembling the implement, the bolt 34- with the thrust washer is passed through the hole 30 in the end of the grip plate 26 before fastening.

The bobbin 41 with a full supply of the cord 37 is then inserted in the open end of the handle. The free end of the cord 37 is passed through the slot 32 into the transverse slot 33 where it is held under the grip plate 26.

The cap 23 has a peripheral reoess or rabbet which fits in the end of the hollow handle. The cap 23 has a stud 38. This stud is knurled on its outer surface so that it may be driven into tight frictional engagement in the cap 23. The stud has an axial screw threaded hole 39 by which it is fitted over the screw threaded end of the bolt 34.

The stud 38 is drilled to provide two right angled holes 40 through which the free end of the cord 37 is passed.

It is evident that the cord 37 may be drawn at will through the stud 33. In order to prevent too rapid delivery of the cord, it is only necessary to grip the plate 26 more closely against the hollow handle 22;, thus clamp ing the cord and arresting its removal.

The implement above described is useful in facilitating the making of a series of knots from a single cord and at spaced intervals along a bundle of wires or the like. The implement is convenient to handle. The discharge of the cord is always under positive control. This cord is delivered at the end opposite the hook, so that there is no likelihood of tangling. The case is readily opened for the insertion of a full bobbin replacing an empty one.

The invention has been described in its preferred form. However, it will be readily understood that numerous changes in minor details or" structure, materials and proportions are possible within the scope of the appended claims.

1. A device for lacing strands which comprises a hollow handle having a thread outlet in its side wall, a head fitted on one end of the handle, a hook on the head, a grip plate overlying the thread outlet and having a portion held transversely in the handle, an axial bolt having a thrust Washer, said bolt extending through the said portion of the plate and into the head, and a cap closing the opposite end of the handle and fastened to the bolt.
