Application December 13, 1933, S erialNo. 702,236 7 3 Claims.

' This invention relates to an improved tool for applying tie wires to paper rolls or other packages, wherein the tie wire is provided at one end with a .knot forother obstruction and is passed through thepaperroll or. package and through central aperturesin metal-disks or heads positioned at opposite ends of the paper roll or package for protecting the latter in transit.

More particularly, the present invention relates to an improved tool for coiling the protruding end of the tie wire so as to draw and tightly secure the metal disks or heads in place at opposite ends of the paper roll or package.

A specific object of the present invention is to provide a very simple tool by means of which the tie wires may be effectively applied in an expeditious manner. a

The invention consists in the novel construction of tool hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing:

Figure l is an elevational view, partly broken away and in section, of a paper roll having the end heads or disks fastened in place by means of a tie Wire applied in accordance with the present invention.

Figure 2 is an elevational view of the tool constructed in accordance with the present invention.

Figure 3 is an enlarged view partly in elevation and partly in central longitudinal section, showing the formation of the free end portion of the tool shank.

Figure 4 is a view similar to Figure 3 illustrating the second step of the operation of applying a tie wire in accordance with the present invention and by use of the tool shown in Figure 2, and

Figure 5 is a fragmentary view illustrating the protruding end of the tie wire completely coiled in accordance with the present invention, the shank of the tool being shown by dotted lines in position as the coiling operation is completed.

The present invention relates to the application or the coiling of the protruding end of a tie wire 5 of an ordinary type which is provided at one end with a knot or other obstruction Sand which is passed through the paper roll or other package 7 and through central apertures of sheet metal disks or heads 8 positioned at opposite ends of the paper roll or package to protect the. same in transit. After passing the binder through the heads and package or paper roll, the protruding end of the tie wire is ordinarily bent or looped at the outer side of the adjacent disk or head 8 so as to secure the two heads in place, and this invention relates to an improved tool for coiling this protruding end of th'e'tie wire so that the heads are tightly drawn in place and effectively secured and retainedagai'nst' the ends" of the package or paper roll "7. i

The tool constructed in accordance with the present inventionincludes a straight metal bar or shank 9 provided with a crank portion 10 at one end and having its other end portion 11 tapered smaller toward the free or terminal end thereof. This tapered end portion 11 has its outer part longitudinally slotted or bifurcated as at 12, and the inner part of the tapered portion 11 is provided with an axial bore 13 whose outer end opens through the bottom of the slot 12. Suitable sleeves 14 may be journaled on the shank 9 inwardly of the tapered portion 11 and on the handle part of the crank portion 10 so as to permit the tool to be gripped at these points without having the hands offer any resistance to free turning of the shank or of the handle part of the crank portion 10 relative to the hands.

In carrying out the presentv invention, the tie wire 5 is passed through the heads 8 and the roll or package '7, and the protruding end of the tie wire has its terminal portion engaged in the axial bore of the tool as shown in Figure 3. The tool is then manipulated to bend this terminal portion at right angles to the remainder of the tie wire as shown in Figure 4, with the tie wire extending laterally through the slot 12 at the inner end of the latter. The shank 9 is then manually turned so as to coil the inner or remaining portion of the protruding end of the tie wire about the tapered portion 11 of the tool shank 9. In coiling this portion as indicated at 15, the shank portion 11 of the tool approaches the adjacent head 8 until the coil is completed and brought tightly against the outer surface of the adjacent head 8. In this way the tie wire is applied in a taut condition with the heads 8 drawn tightly against the opposite ends of the paper roll or package and effectively secured in place. It will be particularly noted that after bending the terminal portion of the tie wire as in Figure 4, the shank 9 is rotated for producing the coil 15 upon the inner part of the tapered portion 11 of the shank 9 so that when the tool is removed the angularly bent terminal portion of the tie wire extends axially of and through the coil as at 16. This produces a neat and compact formation of the protruding end portion of the tie wire by which the disks or heads are secured in place, and it will be seen that due to the tapered form of the shank portion 11, it may terminal portion 16 freely passes out of the bore 13. The coil 15 is extremely efiioient as it emectively resists serious distortion or bending, being considerably more satisfactory than mere looping of the protruding end as heretofore practiced. The above method may be readily and expediticusly carried out by means of a tool which is extremely simple in construction and comparatively inexpensive to manufacture.

Minor changes in details of the invention as herein shown and described are comtemplated Within the spirit and scope of such invention as claimed.

What I claim as new is:

1. A tool for coiling the protruding end of a tie wire, comprising a straight shank having an outer end portion tapered smaller toward the free outer end thereof, the outer part of said tapered portion being longitudinally slotted, and the inner part of said tapered portion being formed with an axial bore opening at its outer end through the bottom of said slot, as and for the purpose described.

2. A tool for coiling the protruding end of a tie wire, comprising a straight shank having an outer end portion tapered smaller toward the free outer end thereof, the outer part of said tapered 1,990,583 be readily withdrawn from the coil 15 while the portion being longitudinally slotted, and the inner part of said tapered portion being formed with an axial bore opening at its outer end through the bottom of said slot, whereby the terminal portion of the tie wire may be entered into said bore and the tool manipulated to bend said terminal portion at right angles to the remaining portion of the tie wire and with said remaining portion extending laterally of the shank at the inner end of its slot so that upon turning the shank the portion of the tie wire inwardly of said terminal portion may be coiled upon the tapered portion of the shank to form a coil having its axis at right angles to the longitudinal axis of the major portion of the tie wire.

3. A tool for coiling the protruding end of a tie wire, comprising a straight shank having an outer end portion tapered smaller toward the free outer end thereof, the outer part of said taperedportion being longitudinally slotted, and the inner part of said taperedportion being formed with an axial bore opening at its outer end through the bottom or said slot, said shank having a crank portion at its other end provided with a handle, and sleeves journaled on the shank inwardly 01 its tapered portion and upon the handle part of the crank.
