BUNDLED WIRE.

Specification of Letters Patent.

Patented Aug. 29, 1922.

Application filed June 14, 1922. Serial No. 568,116.

To all whomit may concern:

Be 'it known that I, SPENCER C. CARY, a citizen of the United States, residing at the city of New York, borough of Brooklyn, county of Kings, and State of New York,

have invented a certain new and useful Bundled Wire, of which the following is a specicasing means with respect to the bundleand the individual components thereof.

According to the invention, a fastening member passes transversely through the bundle and through the encasing means therefor, and this member is in' fixed relation to the encasing means so as to retain the same securely upon the bundle end.

In a practical embodiment of the invention, the encasing means is a'cap composed of compressible material, around which cap is wrapped a part of the fastening member in such manner as to compress said cap into fixed relation to the bundle.

The cap for encasing the bundle end is composed, preferably, of sheet metal formed up to produce a shell and a head integral one with the other, and in order ,to attain the desired compressible formation of said cap, the shell thereof is cut or slitted, said slits extending from a free edge of the shell inwardly thereof to a desired point.

The fastening member is positioned within the end portion of the bundle transversely to said bundle, and it extends tightly for the purpose of compressing the shell of the cap into tight frictional contact with the end portion of the bundle.

It may be added that the encasing means and the fastening therefor are useful in connection with a bundle each wire of which is deformed by producing a flattened portion and a shoulder thereon, and upon assembling wlres of thls formation into a bundle, the flattened deformed portions thereof have a tendency to somewhat enlarge the end portion of the bundle. The encasing cap slitted as described may be slippedwith fac1l1ty over the expanded end portion of the bundle, and by wrapping the fastening member tightly around the cap-below the shouldered portion of the wires, said cap is compressed in a manner to utilize the shouldered wires as a means for preventing end-- wise displacement of the cap on the bundle end.

Other functions and advantages of the invention will appear from the following descrlption taken in connection with the drawings, wherein Figure 1 is a view in side elevation showmg straightened wires assembled to produce a bundle and with. an encasing cap applied :31? the respective end portions of said bun- Figure 2 is a vertical longitudinal section through an end portion of the bundle, the encasing means therefor, and the retaining member for said encasing means.

Figure 3 is a transverse horizontal section in the plane of the dotted line 33 of Figure 2.

Figure 4 is a verticallongitudinal section through an end portion of a wire bundle, illustrating another embodiment of the encasing means for the bundle end.

Figure 5 is a detail perspective view of another form of the slitted cap.

In this art it is common practice to draw wire at a mill, and to coil or wind said wire into a bundle, in which condition the wire is shipped from the mill to the consumer. -Wire so coiled or wound cannot be used to advantage in binding shipping packages with wire, for the reason that the curvature imparted to the wire by the winding operation has a tendency to loop the wire when passed around a package. In view of such condition of the wire the practice is to preliminarilystraighten the wire by subjecting itto the action of a straightening machine, and in this straightening operation said wire is cut in pieces or lengths suitable for use on packages of a certain size. The straightened and out pieces of wire, uniform as to length, are assembled 110 v or cut at d, the slits extendin into parallel relation to compose the bundle. In some instances, the straightened and cut pieces of wire are deformed by a swaglng operation to produce on each wire a flattened and shouldered portion, the same being .useful in connection with certain forms of tensioning implements for the reason that the flattened portion of the wire may be easlly introduced into the implement and the shoulder of the wire co-operates with said implement to prevent slipping of the wire when tension is applied thereto. The individual-wires aie indicated at-A, andthe deformed portion thereon is shown at a in Figures 2 and 4 ofthe drawings.

The wires are straightened, cut to length, and deformed at a, after which a desired number of such wires are assembled into parallel relation to compose the bundle shown in Figure 1 and partly represented in Figures 2 and 4. When bundled, the wire is shipped to the individual users, such as packing houses, merchants, andothers, and in the course of shipment, or in the storage of the wire, it must be handled, so that under such conditions of service, the end portions of the individual wires ma become bent, twisted or otherwise distorte making it a more or less diflicult operation to use the wire in connection with a tensionin implement. n order to protect the wires from distortion underservice conditions, I employ encasing means in the form of a cap- B which, is applied to the end portion of the bundle so as to cover the ends of the individual wires and the deformed portions a thereof see Figures, 2 and l. This cap is composed of-' any material suitable for the purpose, but it is preferred to employsheet metal in the manufacture of the cap, the metal being formed in a well known manner to produce a shell 6 and a head 0 in one integral piece. As shown in Figures 3 and 5 of the drawing, the shell I) of the cap is slitted inwardly from an edge portionof the she I and for a suitable distance. The slits (i may be on lines parallel to the vertical longitudinal axis of the cap, as shown in Figure 5, but

. it is preferred to incline the slits d at an angle to said vertical longitudinal axis, in order that the slitted shell may be compressed to a desired extent without an overlap in the edges of the metal due to a reduction in the diameter of the cap shell when it is compressed.

C is the fastening member extending through the end portion of the bundle and the encasing means therefor, said fastening member belng so related to the cap as to compress the latter into tight frictional contact with the wires composing the bundle at the end thereof. This fastening member 1s shown as a wire, or other flexible material,

and twisted as at d, see Figure 3.

wrapping the end portions of the fastening inserted through the middle portion of the bundled wire, below the deformed portions of said wires. One end of the fastening. wire is passed in one direction around the outside of the cap, as at 0', whereas the other end portion of said fastening wire is passed in an op osite direction, as at 0 around the outsi eof the cap, said two end portions of the wire being brought togetllipr wire around the slitted shell ofthe cap, and by drawing said wire tightly in contact with said slitted shell, the wire operates to compress the slitted shell so that it will have the desired frictionalcontact with the wires of the bundle adjacent the end thereof. The fastening wire is positioned \below the deformed portions of the wires composing the bundle, and the shell of the cap is compressed into tight contact with said bundle and below said deformations of the wires, as a result of which the cap is applied securely to the bundle of deformed wires, and cannot become displaced on said bundle lengthwise thereof, for the reason that the bundle at the deformed portions of the wires is of a diameter exceedin the diameter of that part of the cap whlch is compressed by wrapping the fastening wire exteriorly upon the cap, hence .the cap can be displaced only with difficulty and is not removable until the fastening wire is purposely cut so as to free said cap preliminaryto its removal from the bundle end.

tening wire therefor are adapted for, and may be used in connection with, bundled wire the wires of which are not deformed, i. e., with a bundle composed of straightened and cut wires free from the deformations a. In this event, the slitted cap is applied to the end portion of the bundle to encase the end portlons of straight wires, and the fastening wire is passed through the bundle and the cap, the end portions of said fasteningwire being wrapped around, and drawn tightly into contact with, the slitted shell of the cap so as to compress said slitted shell into tight frictional contact with the bundle. By passing the fastening wire transversely through the bundle and the cap, said wire becomesyanchored, in a measure, within the bundle by reason of the frictional contact of y service conditions of the bundled.

nents of the bundle. This liner. is composed of a relatively soft material such as felt, paper, card board, or other material of a fibrous nature. The liner is confined within the encasing means between the imperforate head 0 thereof and the ends of the individual wires, and the utility of the liner is to protect the head of the encasing means from becoming perforated under the impact of the wires should the bundle be dropped on end, as sometimes occurs in handling the bundle in the stages between storage and shipment of the wire.

As shown in'Figures 2 and 3 of the drawing, the fastening wire is used to compress the slitted portion of the cap, but in Figure 5 the cap is shown as having an annular roove, e, in the slitted part of its shell.

his groove is adapted for the reception of the fastening wire when wrapped around the shell, and said groove affords shoulders against which the wrapped wire lodges, whereby the groove contributes to the security of the attachment of the fastening wire, for the reason that it tends to preclude dislodgment of the wire with respect to the cap, hence the grooved cap and the wrapped wire co-operate in attaining a fixed and nondisplaoeable relation of the cap to the bundled wire.

It is not desired to limit the invention to the use of a cap in conjunction with a fastening wire wrapped around said cap, for the reason that the cap may be contracted at its inner edge around the bundle by means other than the use of the fastening wire. In Figure 4: there is shown a metallic cap E comprising an imperforate shell and an imperforate head, said cap being applied to the end portion of the bundle composed of deformed wires, as heretofore described. This cap is reduced in diameter below the expanded portion of the bundle produced by the deformed wires, and this reduction in the diameter of the cap shell below said deformed wires is brought about by the application of pressure to the lower free edge of the cap shell so as to deflect or crimp said edge inwardly at 6. This crimped edge of the cap shell co-operates with the deformed wires to preclude displacement of the cap relatively to the end of the bundle, thus simplifying the construction by omitting the fastening wire. It may be'stated, however, that I consider the fastening wire used in conjunction with the slitted shell as the preferred construction.

Having thus fully described theinvention,
