WIRE-TIGHTENER.

SPECIFICATION forming part of Lettersvlatent No. 679,870, dated August 6, 1901. Application tiled September 1, 1900. Serial No. 28,738. (No model.)

To all whom, it may concern,.- y

Be it known that I, CHARLES F. STODDARD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi nois, have invented a new and useful Wire- Tightener, of which the following is a specification. i

This invention relates to a wire-tightener.

The object of the invention is to provide a simple and effective means for drawing stay- Vtighten the wire. Fig. 2 is a side view of the same. Fig. 3 is a front view of a bale with the wire-tightener applied and the wire drawn tightly around the bale. Fig. 4 is a side view of the same. Fig. 5 is a front view of a bale with the wire-tightener swung to a reverse position around one arm of the same, so as to bend the wire back upon itself. Fig. 6 is a side view of the same.

In carrying out this invention the two 0pposite ends of the wire which is to encircle the bale are grasped by two arms which are adapted to move away from each other. `A convenient arrangement of these arms is that shown in the several figures of the drawings, in which the upper ends of such arms are pivoted together and the lower ends are free and are provided with a construction adapted to manipulate the ends of the wire, as will be hereinafter more particularly described. While this pivoted arrangement is the preferable form, it is manifest it is not absolutely necessary so long as the arms are capable of being moved against each other and are yet held in a certain relation to each other. Some particular portions of these arms, preferably the lower ends thereof, are provided with means for taking hold of the ends of the wire. A convenient construction for this purpose is shown in the accompanying drawings. The arm to the right is provided with a lip or pro- `and 6 of the drawings.

jection extending at right angles from the outer face of the arm and having a daring or forked slot therein. This slot receives the end of the wire adjacent to the loop, and the lip forms anV abutment to prevent the loop from too readily pulling through. This lip is in the drawings designated by the letter e, and its construction is best shown in Figs. 4

tightening-wire should be passed through the loop and to and through an'aperture or slot formed in the arm D. This slot or aperture is preferably somewhat elongated and inclined to the plane of the arm-that is to say, 65

starting from the outside the slot is cut through the arm in a direction approaching the other arm and at what might be termed an acute angle. This shape of the slot it The other end of the 6o is manifest will cause the end of the wire to 7o bind more tightly in the slot (which is designated d in the drawings) the more tightly the wire is drawn by the spreading apart of the movable arms.

It is plain first loosely applied around the bale and to the tightener the position of the tightener and wire are about as shown in Fig. l of the drawings; but by spreading apart the arms to be seen that when the wire is which grasp the ends of the wire a tighten- 8o ing of such wire will be eected, as shown in Fig. 3 of the drawings. Many eifective devices may be employed to spread apart these arms; but a pair of elbow-levers pivoted together at their angle and having the short end of each connected to an arm and the long end of each projected above to serve as handles has been found in practice to be a most effective and convenient means for the purpose. bell-crank levers ,are shown pivoted together at their angles at the point C and pivoted to the arms D and D', respectively, by the pins A3 and B3. These bell-crank levers are In the drawings these elbow or 9o in the drawings designated by the referenceletters A and B, the short arms of such levers by the reference-letters A2 and B2, and the long arms by the reference-letters A and B.

`The pivot of the spreading-arms isdesignated by the letter E.

As before stated, the upturned lip is designated in the drawings by the letter e and IOO l the flaring slot or cut or notch therein by the letter e'. g r"lhepperation ofthe device is as follows: lhe wire which is to encompass the bale -or other package has formed in one end thereof a loop, and'after such Wire is passed around the bale or package the other end of such Wire is passed through the loop and thestem of the loop placed in the notch of the llpd, so that bhe body of the loop will albut; agalnst the outer side of such loop, wh11e the free end of the fire which has been passed through. the loop is Vnext?passedrdovvn through talle 1711- clined slot in the other arm of the pair of spreading-arms. The handles, which are at this time in the position shown in Fig. l of t-he drawings, are then drawn together, which forces the arms or jaws D D" apart, and as the free end ofthe Wire is gripped in the slot 'd ofthe spreading-arm D and the looprests against the outer side of the lip of arm D "the wire is constantly drawn upon in both directions and tightened, as shown in Fig. 3 of the drawings. After the wire has been tightened the tiglitener is turned back upon itself into the position shown in Fig. 5 of the drawingsthat i's to say, it is turned about arm or jaw D `as an axis-so that arm D is 'swung from the position shown in Fig. 3 over to the position shown near the edge of the bale in Fig. 5, which consequently turns or bends the wire upon itself over the loop, and thereby prevents any slackening of the wire, after which the tightener may be removed. The end of the wire is twisted around the taut part of itself, and thus a permanent tie is effected.

This tightening device is very rapid in its action and veiy edective in its result, so that every particle of slack of the wire is taken up, and the wire can be permanently fastened without any danger of its becoming loosened. Furthermore, With the construction shown an increase of leverage is acquired in the manipulation of the device, with a proportionate decrease of power, enabling the wire to be drawn more tightly against the expansion of the bale than can be accom plished by other hand-operated tighteners.

It is manifest that many modifications may be made in the details of construction Without departing from the spirit of the invention,

and I therefore do not wish to be understood as limiting myself to the exact details shown and described.

What I claim, and desire to secure by Letters Patent, is-.

l. A wire-tightener having two movable parts, each provided with means for grasping thewire, in `combination with bell-crank le- 6o thereof to said movable parts, as and for the l purpose set forth. y

2. A Wire-tightener comprising a pair of Varms or jaws pivotally connected together and each. provided With. means' for grasping the ends of the Wire to be tightened, in combina.- 'bion with' levers pivoted to each. other and respectively connected to said plvoted armasY or jaws, as and for the purpose s ef: forth.

3. Arwire-tghtener comprising a pair of jaws or arms pivotally connected together and having arms for grasping the ends of the wire to be tightened, in combination with a pair of bell-crank levers pivotally connected to each other and each connected to one of said jaws, as and for the purpose set forth. Y

4. A Wire-tightener comprising a pair of arms'or jaws pivotally connected together at the ends thereof and provided with means at the other ends thereof for grasping the ends of the Wire to be tightened, in combination with a pair of bell-crank levers pivotally connected together at the angles thereof, one arm of each lever being pivotally connected to one of said pivoted arms or jaws at a point intermediate the ends of the latter, as and for the purpose set for-th.

5. A wire-tightenei comprising a pair of arms or jaws pivotally connected together at one end, one of said jaws provided at the free end thereot` with an abutment and the other -of said arms or jaws provided at the free end thereof with a slot, in combination with bellycrank levers pivotally connected at the angles thereof, one arm of each of said levers being pivotally connected to one of said arms or jaws, as and for the purpose set forth.

6. A wire-tightener comprisiiiga pair of pivoted arms or jaws, the lower ends of which are respectively provided with a lip having a notch therein, against which lip the loop of the wire to be tightened rests, and an inclined slot in which the free end of the wire is gripped, and bell-crank levers pivoted by their shorter ends to the said arms or jaws and having their longer ends project upward to serve as handles for manipulating the saine; substantially as and for the purpose set forth. In witness whereof I have hereunto set my hand, this 28th day of August, 1900, in the presence of the subscribing Witnesses. A
