BALE TIE Filed March 21, 1934 INVERTER;

-22. fi x Patented Nov. 13, 1934 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to bale ties and more particularly to types of bale ties in which the wire portions thereof vary in gauge and degree of hardness.

It has been the practice heretofore to use bale ties made of 14 to 16 gauge annealed wire. Annealed wire should be distinguished from wire commonly referred to as straight drawn wire. Straight drawn wire has a tensile strength which is considerably greater than annealed wire of similar gauge but is not as pliable as annealed wire. For example, 14 gauge annealed wire has a tensile strength of approximately 300 pounds, whereas 14 gauge straight drawn wire has a tensile strength of approximately 514 pounds. i The drawing of the wire causes it to partake of a hardness commonly referred to as work hardness, and hence will not stretch when in use, whereas annealed wire will' experience considerable stretching. For instance, a 9 foot length of 14 gauge annealed wire, when used as a bale tie, may stretch as much as 5 inches.

It will also be understood that annealed wire having the same tensile strength as a drawn wire will be considerably heavier inasmuch as the annealed Wire must be of larger gauge than the drawn wire. Applicant has found that the only portion of a bale tie which need be pliable or flexible for purposes of tying is the end portion of the tie which is slipped through the loop on the other end when the tie is wrapped around a bale. Therefore, it is one of the important objects of the present invention to provide a bale tie, in which the major portion has less weight than a 35 small pliable section at the free end thereof, and to this end applicant proposes to secure or attach a relatively small section of annealed wire to a relatively large section of drawn wire.

A further object of the invention is to provide improved methods of securing the annealed and drawn sections of wire together, and applicant proposes to accomplish this by welding the enlarged extremity of the drawn section with an end of the annealed section.

45 Other objects will appear in the following specification taken in connection with the annexed drawing, in which- Fig. 1 is a plan view of my bale tie with the straight end portion thereof, or rather that portion which is used in the tying operation, annealed, while the main body of the bale tie is formed of straight drawn wire;

Fig. 2 is a plan view of a bale tie in which the main wire portion is formed of a relatively light gauge of straight drawn wire and there is buttwelded thereto a heavier gauge annealed wire end which is used in the tying operation.

Before referring to the drawing, it might be stated that applicant has disclosed herein a character of bale tie which has the same or greater strength than the ordinary bale tie and still has the advantage of great reduction in weight.

Further, it might be stated that this bale tie combines the advantages of straight drawn and annealed wire in such manner that a more satis- 66 factory bale tie. may be produced at a greatly reduced cost.

In Fig. 1 of the drawing is shown a bale tie which includes the main wire portion 10 formed of relatively light gauge straight drawn wire. A 70 loop 11 of any character may be formed, although in the present instance the loop 11 is formed by bending the wire in a straight line as shown, with the attachment end 12 welded directly to the main wire body portion 10. The straight end, or rather a portion of the straight end, indicated as 13, is annealed with the result that this end of the wire when passed around a bale may be readily and properly drawn through the loop 11 and twisted upon itself in the usual tying operation.

By constructing a bale tie in the manner above described, a bale tie of uniform strength is produced at a muchreduced cost. Considerable saving in expense is accomplished by merely annealing that portion of the wire which is used in the tying operation.

In Fig. 2 of the drawing, the main body of the bale tie has been designated 14, the same being formed of a relatively light gauge straight drawn wire. It is of course well known in wire on drawing that straight drawn wire has greater strength than annealed wire. However, same is not as capable of being so readily bent or twisted.

In this instance a loop 15 is formed in exactly the same manner as shown in Fig. 1, although it is quite obvious that this loop, as well as loop 11 in Fig. 1, might just as well be formed in several other ways. The opposite end of the straight drawn wire 14 has its area increased substantially, as shown at 150., either by one character of mechanical operation or another, and to this expanded end portion is secured by means of a butt-welding operation, a portion of heavier gauge annealed wire which in the drawing has been designated 16. By constructing a bale tie in the above manner, applicant has provided a main wire body portion of straight drawn wire which has the necessary strength with a reduction in weight, this type of wire being better adapted for passing about a bale the tensile strength thereof would be materially decreased, and breakage w'ould occur at the point of annealing; In other words," the enlarged section a'of the'drawn: wire has sufficient length to prevent the annealing heat from traveling as far as-thedrawn wire. 1 In practice, it has conventional annealed bale ties.

been found satisfactory-Etc employ 16 gauge drawn wire for'the larger section 14, and 14 gaugeannealed wire-r-for'the section 16. By increasing the end portion 15a, ofthe 16 gauge drawn wire to a thickness approximating the 14 gauge annealed wire andthenyvel'ding the two sections" together,rthe resultingbale tie has a substantial uniform tensilestr' ngth throughout the entire length thereofi By butt-welding a hea pof annealed wire such as shown -at"1'6 to thestraight drawn wire, applicant has provided a means for satisfactorily tying the bale, it always being advisable of course to have a 'type of wire that is readily twisted upon itself for this tying operation. However, by varying the gauge ofthe wire, applicant has, provided a bale .tie: --of uniform strength throughout with a great reduction of weight and uniformity of strengthand with an added advantage of greatly reduced cost.

From the foregoing it will be apparent that the present invention contemplates the provision ofbale ties which possess numerous advantages over conventional bale ties with which applicant isfamiliar. As previously pointed out, conventional bale ties are usually made .of 14 to 16 gauge annealed wire. A 9-foot length of annealed wire, which has the approximate length ota bale tie, will stretch approximately 5 inches when in use, whereas, by'employ'ing applicant's combined drawn and'annealedwire structure, practically no elongation takes "place, The slight elongation of the small annealed section 16 is negligible.

Furthermore, applicants bale tie gives-the required tensile strength .with the use of'a smaller gauge wire, thereby materially reducing the weight or bulk of the tie. The difference in size and weight is of considerable "consequence when it is understood that bale ties are shipped in bundle form, each bundle containing 250 bale wires. Also, drawn wire costs less'than annealed wire of the same gauge, and hence applicants bale ties may be more economically produced. In fact, applicant is'able to produce the combined drawn and annealed tiejstructure with a saving of at least 22 percent "over the cost of producing To this saving must also be added the saving in freight resulting from the decrease in Weight and bulk. Furthermore, the eificiency of applicants bale tie is greater than conventional ties, inasmuch as the tensile strength of applicants combined wire sections is greater'than the tensile strength of the usual annealed wire bale ties.

In addition to reducing the stretch or elongation of the bale tie to a negligible amount, attention is also directed to the fact that applicants drawn wire section 14 is applied to the when compared w 1' liability or wire, the tying maygbe effected with the required degree of ease.j,Furthermore, applicants described arrangement, in addition'to reducing the weight andincreasing the tensile strength,

overcome the mairr disadvantages that attend the useof any of the known or patented types of bale ties.

My present invention is not directed to any specific form of wire receiving meansor loop.

In other words, various forms of wire receiving means or loops may be employed without departing from the spirit and scope of this invention;

I have made reference herein to straight drawn wire, and, for purposes of clearness, it

should be understood that this is the type of conventional wire commonly referred to by wire manufacturers as bright h'ard drawn wire or bright basic hard drawnwire.

What I claim is: 1

1. A wire bale tiehaving a wire receiving means at one end, them'ain wire portion of the bale tie being formed of straight drawn wire and the other end being more pliable to permit tying thereof to the receiving means.

2. A wire bale tie having a wire receiving means at one end, the main wire portion being formed of relatively light gauge straight drawn wire and the other portion being formed of heavier gauge more pliable wire ,welded to the first mentioned portion.

3. A wire bale tie having a wire receiving means at one end, the main .wire portion being formed of relatively light gauge straight drawn wire with a small portion adjacent its end substantially increased in diameter and a strip of heavier gauge wire welded to said expanded portion.

4. A wire bale tie having a wire receiving means at one end, including a main wire portion of a larged extremity a length of wire of heavier gauge,

and welding the abutting parts together without subjecting the smaller gauge wire to annealing heat. 7

'7. The method of producing wire bale ties including the steps of enlarging one extremity of a relatively small gauge drawn wire; positioning a length of heavier gauge annealed wire in abutting relation with said enlarged extremity, and welding said abutting parts together without causing the drawn wire extending beyond the enlarged extremity to experience annealing heatr ALVIN V.
