skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which .form a part of this specification.

Our'invention relates to a machine for the manufacture of bag-ties consisting of aring composed of stout flexible wire. Bag-ties of this kind are formed of a piece of wire of suitable length, the ends being brought together and twisted about each other. The ties are applied by slipping the ring over the folds of the closed end of the bag or sack and by then twisting the ring tightly upon the neck of the bag by means of a suitable instrument held in the hand of the operator. This tie does not injure the sack and is readily and easily untwisted and removed to open the sack.

Our invention relates, more particularly, to mechanisms for rapidly taking wire from a coil, forming it into a ring of suitable dimensions, cutting off the wire and twisting the overlapping ends of the wire around each other to form a smooth stout ring, for the purpose indicated.

To this end our invention consists of the devices, construction and arrangement of parts hereinafter described, and shown and illustrated in the accompanying drawings in which,,

Figure 1 is a top-plan View of our machine; Fig. 2, a side-elevation of the same; Fig. 3, a section seen from the right in Fig. 2, of the feed-mechanism hereinafter referred to; Fig. 4-, a side-elevation of the .formsthe case {for retaining the twisting gear hereinafter referred to; Fig. 8, a topplan view of the same; Fig. 9, a side-elevation of the other of said bars; Fig. 10, a topplan view of the same; Fig. 11, a front and side elevation of the twisting-gear hereinafter referred to, detached; Fig. 12, a side elevation of a modification of said twistinggear in place; Fig. 13, a top-plan view of the same; Fig. 14-, a top-plan view of the ends of the wire tie twisted together by my device, and Fig, 15, a side elevation of the same.

Like parts are represented by corresponding numerals throughout the drawings.

This apparatus, designed to produce rings of the particular kind indicated, consists primarily of a machine-bod or base 1, upon which the various parts, now to be described, are suitably supported, such bod being raised by means of legs or a bcnch,not shown;- to a suitable height above the floor. Journaled across one end of the frame is adriving shaft 2, which, through beveled gears on counter-shaft 3, drives a shaft 4 journaled across the opposite end of the frame. The wire 5, to be formed into rings or ties, is drawn through straightening rolls 6 by means of feed-rolls 7 driven by gear 8 on shaft 3 meshing with one of the gear-s9 on the shaft of one of the feed-rolls. The wire passing between the feed-rolls is led by a guidetubc 10 to a point indicated at a Fig. 3, where the next step in the formation of the tie begins. Although the rotation of the feed-rolls is constant this feed of the wire is intermittent, as the gripping surfaces of the rolls do not extend around their entire circumference. One of the rolls is adjustable axiall to vary the arc of gripping contact and t 1e consequent feed of. the wire at each revolution of the rolls. (See Fig. 3.)

11-11 are a pair of like disks rigidly mounted upon the adjacent ends of two shafts 12-42. These shafts are journaled longitudinally ofthe frame in pillow-blocks or pedestals 1.&*13"--13"-'-13 and have a rotary movement in their bearings as well as a longitudinal movement toward and away from each other and with each other, as hereinafter explained. The margins of the meetingfaces of the disks are slightly beveled so that when the two disks are brought together they form a cylinder having a sharp circumferential groove 11 One of the disks is provided with a transverse hole 11", which,

The second in the manufacture of our ti -thesis the forming of the loop,--hcvbeen completed, the next step is to sever the wire, in ween the feed-rolls and the disks 11, which shop is performed by the meclmuism new to he described.

The next step in the formatioh of the tie is to wrap or coil these overlapping ends around each other, as illustrated in Figs. 1% and 15, and to time complete the tie. 'We accomplish these steps by means of the mechanism now to be described.
