Filed Oct. 10. 1929 ATTORN EY l atented Sept. 8 1931 UNITED STATES HENRY B. FOULDER, F GLENBROOK, CONNECTICUT TIE TWISTING TOOL Application filed October 10, 1929. Serial No. 398,588.

This invention relates to tie twisting tools, and more particularly to the heads of such tools.

In an application filed by me December 14, 1928, Serial No. 326,125, I have disclosed a tie twisting spindle having a stationary jaw and a jaw movable toward the stationary jaw to grip a tie therebetween, so that when the spindle is rotated the tie engaged in the jaws will be twisted. The ends of the ties enter between the aws endwise,'and are then gripped thereby. Often one end of the tie is more advanced than the other. Sometimes this prevents one end of the tie 5 from being engaged by the jaws at all, and

often the ends of the twisted tie are not symmetrically placed, which is objectionable.

The principal object of this invention is to provide a head for a tie twisting spindle,

which head is so constructed that it will cause the ends of ties entered between its jaws to become symmetrically positioned, and thereby to insure the engagement of both ends of the ties by the head and their symmetrical location in the twisted ties, irrespective of one end of the tie being further advanced than the other as the tie is entered between the jaws of the twisting head.

Another object of this invention is to 3 provide a tie twisting spindle head of the character described which is simple, sturdy and durable in construction and positive and eflicient in operation.

Further objects of this invention will be in part obvious and in part pointed out hereinafter.

In accordance with this invention, a stop, such as a shoulder or ledge, is provided in v .the head immediately to the rear of the tie engaging surfaces of the gripping jaws. When a tie, with its ends brought near to gether, is advanced endwise between the jaws from the front, both ends will be brought into abutment against the stop, thus insuring the entry of both ends of the tie into the jaws and their symmetrical placement, even though when the tie first enters the jaws one end of the tie is in advance of m the other. This also bows the tie ends some what, giving a more convenient grip for untwisting the tie.

A suitable twisting spindle for such head, means for operating the spindle and head, and means for advancing ties into engagement with the head are fully disclosed and claimed in my said prior application, and are not claimed herein.

In order that a clearer understanding of my invention may be had, attention is hereby directed to the: accompanying drawings, forming a part of this application, and illustrating certain embodiments of this invention, and in which: l V

Fig. 1 is a top view of my improved head, with a portion of the top jaw broken away, the View also showing the twisting spindle and certain associated parts shown in my said prior application, and a tie completely entered into the head;

Fig. 2 is a sectional view of the same, and is taken on the line 22 of Fig. 1;

Fig. 3 is a'fragmentary view of the head, showing a tie only partially entered into the head, and before it has been completely ontered, as shown in Fig. l.

F 4 is a plan view of a twisted tie; and

Fig. 5 is a fragmentary perspective view of the jaws on enlarged scale.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring to the drawings, the tie twisting head 1 comprises a stationary jaw 2 and a cooperating movable jaw 3 pivoted to the head at 4. On the jaws, inward of the gripping surfaces, are shoulder portions or abutments 5, forming stops for the ends 6 and 7 of a tie 8, and causing the tie ends to be in alignment when finally seated and gripped between the jaws, and also bowing them to some extent, as shown in Fig. '4.

Should one end of the tie be in advance of the other when the tie ends enter the jaws, as shown in Fig. 3, the trailingend will continue to move into the jaws until it comes against the stop 5 and even with the advanced end which has previously been stopped by one of the shoulders 5. Thus both tie ends indicated diagrammatically at 21.

will be even when gripped between the jaws and twisted. 7

As afore stated, this construction insures the seating of both ends of the tie completely and in alignment in the jaws, and avoids the possibility of only one end of the tie being gripped, or uneven twisting, or mis-alignment of the ends in the twisted tie, due to the ends being out of alignment when the tie is advanced into the head. The appearance of a tie 8 twisted by means of such head is shown in Fig. i.

Preferably a division wall or partition 9 is provided on the stationary jaw 52, and penetrating a slot in jaw 3 to keep the tie ends on the proper sides of the head and to cause the ends of the twisted ties to remain separated to some extent to facilitate untwisting.

In order to show the head in a suitable environment, it has been illustrated as being mounted on the spindle disclosed in my said prior application, and certain associated parts are also shown.

These include a turn-table 10 having a cover 11 in which the spindle 12 is mounted for rotation, by means of gears 13, and for longitudinal shifting, by means of lever i l, and collar 15. Numeral 16 indicates the lever, which is connected to the heel portion 17 of jaw 3 for operating this jaw. The turn-table has bag-holding notches 18 about which are the guide pieces 19 to guide the tie end across opposite sides of bags 20 in the notches and between the jaws 2 and 8'of head 1 when advanced by the tie advancing means,

As many changes may be made in the environment of this invention without departing from the scope thereof, it; is to be understood that all matter disclosed herein or shown in the accompanying drawings shall be interpreted as illustrative and not in a. limiting sense.

Vhat I claim is 1. In a tie-twisting head, in combination, two cooperating tie gripping surfaces and a stop the rear of and at all times fully bridging the space 7 between said surfaces adapted to engage and align the ends of a tie entered into the head from the front.

2. In a tie-twisting head, in combination, a stationary jaw having a tie gripping surface, a cooperating movable jaw having a tie gripping surface, stop means at the rear of said gripping surface adapted to be abutted by the ends of a tie entered into the head from the front, for aligning said tie ends, and a partition on the stationary jaw dividing its gripping surface and adapted to keep the ends of an entered tie disposed toward opposite sides thereof.

3. In a tie twisting head, in combination, two cooperating relatively movable gripping jaws, and a partition member dividing the gripping surfaces of both of said jaws latertherefor in the other aw.

This specification signed this 8th day of October, 1929.
