BME TIE WITH DEFORMED ENDS.

Application filed June 14, 1922. Serial No. 568,302.`

To all whom t may concern:

Be it known that we, ALEG J. GERRARD and PARVIN WRIGHT, respectively a subject of the King of Great Britain and a citizen of the United States, both residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bale Ties with lDeformed Ends; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bale ties, or tie wires, having deformed ends, especially adapted for use in connection with wire tying machines, such as those disclosed in our copending application #525,908 filed December 31, 1921, and entitled lVire tying machines. i

Ithas for its object to provide a tie wire which will be simple in construction, comparatively inexpensive to manufacture, and more eiiicient in use than those which have been heretofore proposed.

With these and other objects in view, the invention consists in the novel details of construction and combinations of parts constituting the tie wire, all as will be more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification, in which 'like numerals designate like parts in all the views:

Figure 1 is a diagrammatic elevational view of a machine adapted to use these particular tie wires;

Figure 2 is a side elevational view of one of the wire holdingposts employed in said machine.

Figure 3 is an end elevational view of the post and wire shown in Figure 2;

Figure 4 is a plan view of a deformed end of the tie wire;

Figure 5 is a -view of the parts shown in Figure 4, when turned through an angle of 90 degrees;

Figure 6 is a view of the knot which is tied with this particular tie wire;

Figure 7 is a diagrammatic view of the coripleted tie wire after the knot has been tie Figure 8 is a diagrammatic view on an enlarged scale, of. one form of notch or deff has recentlv been developed wire tying machines of the type illustrated in Figure 1. which puts two parallel bights of the tie wire under tension after it has been wrapped around a box, and then while these bights are under a considerable strain. the said machine twists them together into a knot. lt is desirable that the ends of the wires used in these particular machines be deformed as illustrated in Figures 4 and 5, for the deformation of their ends affords a number of 7&3

advantages in the practical use of the machines which can only be appreciated from a general knowledge of the construction and operation of the machine itself. and such an operation may be understood from what follows:

As is more fully disclosed in our cepending application above mentioned` 1 indicates the frame work of a machine especially adapted to employ these tie wires, 2 a hold- 85 ing post for one end of the tie wirel 3 a housing enclosing a twisting mechanism adapted to twist together parallel bights of the tie wire, 4 a second'.holding post surrounded by a cutter 5, for cutting oft4 one 90 of the bights after the twisting operation` 6 a means for putting a tension on the tie wires before the twisting operation. 7 a means Vfor operating the tensioning means (i.

and 8 represents a package around which 15 the tie wire is passed prior to the tensioning, twisting, and cutting operation.

The machine is adapted to rest upon the top of the package 8 and a deformed end 9 of the wire 12 being inserted in the post. 160

while the other end 13 of said wire is secured to the ratchet 6, an operation of the lever 7 will put a very considerable tension on the parallel bights 10 and 11 of the wire. while an operation of the handle 14 will cause said 105 bights when still under tension to be twisted together as illustrated in Figure 6. Now. if no deformation were provided in the end 9 of the wire 12 some other means would have to be employed which would not 119 only securely hold the wire during the tensioning operation, but would also enable one to readily introduce the wire -into the machinev before the twisting operation and to as readily remove it after said operation. Such devices, however, have in all cases been found very slow in practice and also objectionable in that they usually bite into the wire when under strain and thus are the wires liable to pull loose.

By employing a deformed end for the tie wire, such, for example, as a notch 15, on the other hand, which may be formed by' a displacement of the metal, a shoulder 16 is provided against which the edge 17 of the holding post 2 takes. A flat portion 18 is also provided in the. deformedend, which enables the operator to insert the wire into the slot 19 of the post with his left hand, leaving his right hand free to train the `wire around the box. The metal being displaced to form the Hat portion 18, and not removedL the wire is not weakened as a whole, and further, as the depression or deformation` 15 is made by a'die action the skin of the metal is so compressed that it is found that the wire breaks under tension at other places rather than at the deformed end.

Another very important advantage that iows from the deformation 15 resides in the fact that during the tensioning operation. the edge 17 of the post forces theextreme end 9 downwardly as illustrated in Figure 3, the companion edge 20 of the slot 19 being cut away orV rounded od' to admit of this movement. yThe result of bending down the end 9 of the bight 11 of the wireis to make it lie down snugly against said wire in the finished knot, instead of permitting it to stick up and form a snag to tear the hands of the operator or to rip open other packages that are slid over it, which often happens with prior knots.

1n the same way, whenthe rotary cutter 5 is operated to sever the'bight 10 of the wire at the end of the twisting operation,l

its cutting edge 22 bends down the severed end and causes it to lie down snugly alongside the body of the wire, instead of leaving it to stand up and tear the hands of the operator, or to rip open other superposed packages when they are moved. The result is the twisted knot shown in Figures 6 and 7 having each of its ends tucked down. alongside the body of the wire. l

lt has been found in practice that if the shoulders 16 of the deformed end of the wire are made sloping as in the drawings, the extreme end or head 9 will hold, while the main body of the wire breaks under strain, as above stated, but on theother hand, ithas been found if said shoulders are more abrupt as indicated at 25 in Figure 8, the head is not so strong and may break before the wire body breaks.

lin making these tie wires, it is convenient to deform both ends of the same as indicated in Figure 10, for when very small boxes are wired, the severed portions will have a deformed end and may itself be used as a tie wire.

lt is obvious that those skilled in the art may vary the details ofl construction as well as the arrangement of parts without departing from the spirit of the invention, and therefore we do not wish to be limited to the above disclosure except as may be required by the claims.

What is claimed is:

1. A .tie wire provided with a deformed end and having parallel portions thereof` twisted together with said deformed end bent down alongside of the main wire body, substantially as described.

2. A. tie wlre knot composed of oppositely extending twisted bights of the same wire having one of its ends deformed and l its other end of a normal shape', and having its deformed end disposed down alongside of the main body of the wire below the top surface thereof, substantially as described.

3. A tie wire knot composed of oppositely extending twisted bights of the same wire having one of its ends deformed and its other end of a normal shape, and having its deformed and normally shaped ends disposed down alongside of the main body of the wire below the top surface thereof, substantially as described.

1n testimony whereof we aiiix our signa- 100 tures..

ALE@ d. GERHARD. PARVN WRIGHT.
