Our invention relates to n device for wiretying bags and has for its object to provide means whereby ties muy be easily twisted upon the bag and the wire-tying device ensily eindV autonmtiea-lly released from the tie.

It is illustrated in the accompanying drawings wherein- Figure 1 is a. side elevation of the device with'the bag and tie in position;

Fig. 2 is a similar view of the same with the tie completed;

Fig. 3 is e similar view tie has been released;

The object of this etrange ment, of Course, is to cenere e. rotational movement of the hook relatively slow with reference to the movement of the handle et the beginning of the twist. The slow Ditch. of Vthe spiral nt the l'ieginning gives inore power with refer-mice to the mnonnt of twist effected sind it is :it that point that such power is required. As the pitch increases, the twist being" well started. less power is required. This Glow pitch if; indicated by the letter G.

W e do not wish to be limited to the 'par lienlnr form. size. oro-portion end arrange ment of these seri-eral parte. as. obviously grunt elmog'es could be inode Without departing' from the spirit of our invention. We wish our drawings to be tnleh in n sente as ding'rmnrmitie, although they do repren sont an operative device.

Tliehooke B, B3 in the preferred forni zure formed of n single integral thin plete perpendicular to the shank B? and som1- ranged that the slot between them and the member l will be comparatively deep and narrow. This is am advantage but not ebso lntely essentiel und the piece would function properly if the slots were not S0 deep; but with the device nrrnnged ns shown, the Slot-S being em'vfd about. the center .of rotation, the opemtiv n is better than if' the arrangement Vwere slightly di'erent.

The use and operation of our invention. are es follows:

Assuming that the parte are in the position shown in Fig. 1, the link C being against the breast of the operator, the tie loop havingY lmd its two ends caught in the two hooks while its body portion is gathered around the top of a puckered bag to completrl the tie it is only necessary to brin the handle to the limit of its motion towar the operator or toward the left. This Will cause the rod A to rotate and that rotation will rotate the hook in the direction indicated by the arrow in Fig. 5, thus tendin to keep the 'upset ends of the tie loop in hoo ed relation. The tie will now be twisted as indicated in Fig. 2 so as to complete the tie and tighten it about the bag.

The sleeve or buffer member E4, with its end E3, is operatively connected to the tie holder, and with the spring E2 and bulier E3 always normally in contact; While the s ring is compressed by the pushingl in o the buffer member by striking against the ring or collar C2 only at or near the end of the tie-twisting movement. At this time, when the operator releases his hold on the handle D, the compressed spring presses against the handle D and thereby causes the reverse turn on the shaft which releases the Wire tie from the tying hooks, and the parts E* and D are again pressed apart from the position shown in Fig. 2 to that indicated in Figs. 3 and 4.

In thus moving the handle to the limit of its motion toward the left as indicated in Fig. 2, the spring E2 will be compressed and if then the handle be free this spring will force the handle toward the right, thus rotating the hook piece slightly in the reverse direction and dlsengaging the hooks from the ends of the Wire tie. This is very inlportant in the use of such machines or tools. They are generally used by more or less inexperienced help and any effort required to manipulate or operate the tool beyond what is absolutely essential should be avoided. 'lhe automatic release due to this retraeting spring is very effective in releasing and disi-hargng the tie and therefore the bag and greatly facilitates the operation, for the op' eralor immediately upon completing the tie roh-ases the handle and proceeds to manipulatil another tie without havingr fo stop to lsengage the tool. The importance of this will be evident when it is remembeiml that lensrol'` millions ot such bags are wire-tied every year.

Attention is called to the fact that the ,spring hnller arrangement is 5so arranged lhutwhen the twisting movement has been comph-led the spring then cornes into operation lo return the pa rtal and rotate them lhrougg'h a short distant-e so as lo dismigago the l'ie-holdir from lhe lie. Attention 'is also walled to the .simplicity of lhe device wherein the axes ol' the slots are )arallcl with the axis of rolal'ion oi' the lwistlng tool andso parallel with the wire ends as they are twisled. The slots are deep and ual'- row and are substantially concentric. Since these slots are curved and curved about the center of rotation of the twisting tool, it is obvious thattlley take hold of the wire, and the rotation of the tool tends to lock the wires into the slots, and because they are curved it is eas for them to be disengaged by the relatively light pressure `of the releasing spring.

It willbe observed that the s rin bulier is so arranged that it rotates t e s ank in the opposite or untwisting direction substantially through one whole revolution so as to disen age the hook from the ends vof thevties. learly, if the resistance is ve great, the spring may not rotate the hoo throu h a whole revolution, but under no conceivable circumstances will there be such a resistance as will make it impossible for the hook to be rotated back far enough to tive tqkrotate the parts in the opposite irection only at the end of the twisting movement.

A wire-tie twisting tool-comprising a. tie holder having parts adapted to hold the ends of the tie and `faced in the same rotational direction, means for rotating the holder in one direction to twist the tie, and means for automatically rotating it approximately one revolution only in the opposite direi-tion at the end of the twisting action to release the tie, said means comprising' a spring, a buffer member. o eratively connected to the-tie holder, t e spring and buffer member being 'so positioned that they como in contact with one another and the spring is compressed only at the end of the lie twisting movement.

'3. A wire-tie twisting tool comprising a tic holder having projecting Slotted parts, the slots being deep and' narrow and open on opposed sides ol' the slotted part inthe same rdtational direction, said slots being parallel with the axis of rotation ot the twisting tool.

fl. lu a. wire-tie twisting tool comprisinga shank aud means `l'or rotating` it,.a pair of curved lingers forming an S-sliaped hook lwilli narrowV deep slots curved about the centi-r ol" rotation ol' the shank and o ponin,f \r in the same rotatiolnil direction.

In a wire-tie twisting lool comprising it, a gait' of bape hook with narrow doop slots curved about the' contar of' rotation of the shank and opening in the same rotational direction, Said hooks being formed of a single integral thin plate perpendicular' to the Shank.
