Be it known that I, LE DRU R. PoMERoY,

a citizen of the United States of America,

residing at Toledo, Lucas County, Ohio, have invented new and useful Wire-Tying Tools, of which the following is a specification.

This invention relates to strand twisting means.

This invention has utility when incorporated in a device for rotating a pair of spaced ends of a Wire which is looped about a sack or bag opening for thereby closing such opening.

Referring to the drawings:

Fig. 1 1s a side elevation with parts broken away of the device .as a wire tie tool A for a sack with the wire tie in position ready to be tied;

Fig. 2 is a side elevation with parts broken away of the device of Fig. 1 with the tie in position just as tripped after being tied;

Fig. 3 is an end elevation of the head with its coacting jaw;

Fig. 4 is a plan view of the head and jaw in position as shown in Fig. 1;

Fig. 5 is a section on the line V-V Fig. 1; and

Fig. 6 is a section on the line VT-VT 13g. 1.

A hollow actuator, grip or handle 1 is shown as provided with a pair of opposite or diametrically dis osed bearing seats or lugs 2 on its inner tulbular portion, and longitudinally spaced therefrom as well as at an angle thereto a second pair of bearing seats or lug members 3. These lugs or seats 2, 3, coact with a pair of helical ways 4 in a stem 5 extending through the handle 1.

This stem 5 projects from one end of the handle 1, to form a head 6 terminatin in a pair of radially extending diametrically spaced seat 7 (Fig. 3), between which seats 7 is an upstanding portion or spacing tongue 8. These seats are termed diametrically extending because they approximate a line transversely of the axis of rotation of the head and in a right line passing through the center of the polygonal bulging figure formed by the jaws as shown in end elevation in Fig. 3. A pivot pin 9 approximating diametrical relation to the stem 5, mounts a .swingable holder or jaw member 1() which has a air of diametrically spaced radially extendlng seats 11 cgacting to oppose the "spring 18 may seats 7 and thereby complete a pair of notches at the terminus of the head 6. Each completed seat or notch 7,11, 'hasl its inner face or wall 12 beveled or 'inclined forwardly. Accordingly when upset heads 13 of a Wire tie 14, are seated in such head' 6 and a pull is made on the handle 1 there is a tendency to force the jaw member or holder stem 5, there y normally thrusting the rod 16 into position to hold the member 15 for' maintaining the holder or jaw 10 in position to keep the notch seat portions 7, 11, against each other or closed. Protrudin beyond the side of the stem 5 remote for t e head 6, there is a iian'ge 20 :fast with the rod 16. In operating the de# vice or toolof this disclosure, with the pair of heads 13, one in each guide way or notch 7, 11, and the handle in the position shown in Fig. 1, a quick vigorous pull of the handle 1 away from the wire 14 results in a rotation of the head 6 las the handle 1 is held against rotation and reciprocated away from such head. en this handle 1 reaches the limit of its travel along thestem 5 by having the flange 20 enter a recess 21 in the handle 1, this dan 20 is moved away from the stem 5 and such movement causes the rod 16 to move through the collar 19, into the stem 5 and the member 15 to move away from under the jaw 10. The 'aw is thus free for opening as shown in thus operating the tool may be a jerk and without concuion for the 4menriber 16 in itstravel 'toward' the stem 5 strikes helical spring 22 mounted in such stem 5 and held in position by being on the rod 16. This spring 22 accordingly serves as a buer.

For variation in the sizes of sacks or the thickness of material of the sacks, so that range of tightne may be changed when using the same tool over a range-of con-v tainers, provision is made for adjusting. the

region of twisting for the tie, whenfthe same length ties are used. Aa shown hereinigj2. The pull inime ` which may be mounted a member 25 having a slot 26 in which may engage bolts 27 adjustably anchoring the member 25 against the head 16. This member 25 is shown as having an angular forward extension 28 extending into the region of the tongue 8 but forwardly of such tongue so that it mayvary the spacing of the tie wires 14 at different distances from the head 6, and thereby result in the. twisting occurring more remote from the head 6 and thus closer to the ba being tied, for tightening such tie.

hen the tool is thus automatically released from the sack or container being tied by the-wire tie, spring 18 automatically effects a resetting ofthe tool by throwing the rod 16 toward the head 6 in which travel the member 15 rides against cam 29 and rocks the jaw or holder 10 back into starting position so that the next pair of heads 13 of a tie wire 14 may be introduced into position with the loop around the bag opening 23. The handle 1 may be heldup to allow the stem 5 to run back by gravity therethrough to initial position adjacent the head 6, which travel is limited by collar 30 on the stem 5. As herein shown the seats 3 are in a collar or rin 31 having an annular groove 32 engage/d a set screw 33. In providing this loose colar 31, a variation in the pitch of the helical ways 4 may be taken into account, with the advantage in practice of less torsional resistance in the longer pitch portions near the head 6. This is a feature materially contributin to ease ofoperation, as well as speed, for t e twist pull does not meet with its greatest resistance until it has accumulated momentum.

The progressive Ior varying pitch thus means that the longer pitch portion of the ways i in the stem 5 at the starting pull efects twisting with more ease, although through a longer travel distance for the handle 1. With the twisting thus easily started, the continued pull meets with greater resistance as the pitch is shorter, thus increasing the twisting rate per unit of distance traveled by the handle 1. However, the momentum of the parts from the quick jerk at starting makes such increased resistance negligible in practice, and the total of operation is gauged by the ease of starting.
