BALE TIE.

Application filed March 13, 1922. Serial No. 543,155.

To all whom it may concern:

. Be it known that I, JOHN W. LnsLrn, a citizen of the United States, and resident of Evanston, in the countyofCook and State of Illinois, have invented a certain new and useful Improvement in Bale Ties, of which the following is a full, clear, concise, and exact description, reference being hadto the accompanying drawings, forming a part of i this specification.

Then a wire bale tie of any one of the types heretofore employed is applied to a rigid boX or similar package, the tie is apt to be somewhat loose for the reason that the workman applying same has no way of determining the limit to which it may be safely stretched. If such a tie is stretched too tightly it will break or become overstrainedyand thus unreliable. Ordinarily, a workman applying a wire bale tie being apprehensive of breaking or overstraining the tie fails to stretch the tie to the most desirable extent. This is especially true when the workman uses certain types of wire stretching tools in which the direct stretchin g pull is supplemented by therotation of the entire tool around an axis located substantially at the loop of the tie. This sec ond operation applies tension to the tie under considerable leverage and in those cases where the primary stretching operation has been carried too far the tie will break in this secondary operation. This is a very frequent source of tie breakage.

My invention contemplates the provision of a wire tie which is so constructed that it will yield somewhat when it has been sub jected to a tensile stress slightly less than that required to overstrain it. A workman applying a Wire tie of this character may stretch the same to the desired degree of tightness without fear or apprehension of breaking or overstraining it. y p

In the accompanylng drawings illustratmg my invention Figure 1 illustrates one of the tiesof my.

invention extending around a boX and ready to be tightened thereon;

Figure 2 is a fragmentary plan view on an enlarged. scale of the ends of the tie shown in Figurel;

Figure 3 is a view similar to Figure 2; but illustrating the preformed loop of the tie as it appears after the tie has been stretched to a degree slightly less than that required to overstrain it;

Figure 4 shows the ends .of the tie as they appear after the formation of the second loop, and

Figures, 5, 6 and 7 are views similar to Figures 2, 3 and 4, but illustrating a modified embodiment of my invention.

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

Referring first to Figure 1, at A I have illustrated a box or carton around which one of my improved wire ties has lJGBIlBX- tended. The tie is indicated at B. It will be notedthat one end of the tie has been conformed and twisted upon itself to proyide an eye or loop C. The eye or loop G is formed prior to the application of the tie to the package, and will usually be made by the manufacturer of the wire tie rather than by the user thereof.

Referring now to Figure 2, it will be noted that the eye or'loop C as there shown is substantially heart shaped. The important features of the loop, however, are the abrupt angle bends 0-c. I have found that when my improved tie is stretched in angle bends 0c open. In applying my improved tie to a package of the type illustrated in Figure 1, the end D of the tie is passed through loop C and is drawn up to stretch the tie until the abrupt angle bends c a open as illustrated in Figure 3. The workman thereupon twists the tie end D upon itself to form a second loop E which interengages with the loop C. The tie has now been properly tightened, and applied to the package. Icontemplate that a suitable tool or tools will usually be employed for stretching the tie and for forming the second loop E. Tools suitable for my purpose are now known to persons familiar with the art to which my invention relates hence it will be unnecessary for me to illustrate or describe such tools.

It is satisfactory to have the abrupt angle bends c0 open just slightly before the tie has been stretohcdzto the extent necessary to over-strain it, because when the bends 00 open the preformed loop C lengthens slightly. andtherefore, to a smalLextent, re-

lieves the tension under Whi'clithe tie hasbeen placed.

The embodiment of my invention illus trated in Figures 5, 6 and 7 differs from that shown in the preceding figures in that the preformed loop 0 is initially triangular insliape, in this case it being the base ofthe triangle which is engaged bythe tie end D when the'latteri is drawn through the preformed loop The abrupt a11glebends-00 serve the same purpose in both of the ill'us trated embodiments of my invention.

1 donot limit myself to the particularembodiments ofmy invention herein shown and described; as- I appreoiatethat: my invention may be variously modified without departing from the scope of theinvention covered by: the appended claims.

hat:lzclaimisanew and desire to secure by. Letters Patent of the United States is:

1. Themeth'od which consistsin passing around a package a wire tie having one end thereof conformed and twisted upon itself toprovide a polygonal loop, drawing the unlooped end of the tie through said polygonal loop until said polygonal loop becomes appreciably narrower, and then twisting the unlooped end of the tie upon itself to form a second loop which interengages with the first-1nentioned loop.

2. The combination with a package, of a tie wire encircling said package, one end of said wire having a loop formed with abrupt angle bends therein, anda loop on the other end of said wire interengaging with said first loop, said second loop being formed by passing the end of said wire through said first mentioned loop and then twisting said wire back upon itself, the abrupt angle bends in said first loop indicating by their angle the tension of said tie wire.

It witness whereof, I hereunto subscribe my name this6th day ofMarch, 1922.
