Specification of Letters Patent.

Patented July 30, 1912.

Application led June 6, 1910. Serial No. 565,224.

To all 'whom t may concern:

Be it known that I, ARTHUR L. RUSSELL, a citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Viring Devices, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to wire anchoring apparatus and has for one object to provide improved means for anchoring a wire to a tack or the like.

Another object is to provide means by which a wire can be place-d and tightened into binding relation to t-he work, as for er;- ample, about the toe portion of a lasted shoe, and then anchored while held under tension,

A further object is to provide a hand tool by which a workman can string a wire about the toe of a shoe in the process of lasting and drive a tack and anchor the wire.

An important feature of the invention consists in means for holding a wire adja cent to a tack stem or to the path of an ingoing tack and means actuated by the downward movement of the tack driver or the like for wrapping the wire around the stem of the tack. Heretofore it has been proposed to bend a wire around a tack by force applied in the plane in which the wire was to be bent or in a plane parallel thereto but in accordance with this feature of the invention the wire bending movement is taken from a member moving perpendicularly to the plane of the wire.

In the preferred embodiment of this invention the apparatus includes a tacker, the driver of which acts through a spiral or in clined connection with a sleeve to twist the wire around the tack which is being inserted. It may, however, be embodied without further invention in an apparatus which will wrap the wire around a previously driven tack.

A further feature of the invention is found in means constructed and arranged for use in carrying a wire around the object to be bound and having means for anchoring the wire; Preferably said wire carrying means will be formed to adapt it to place a wire under tension in holding relation to the work, as for example, between the retracted wipers and the upstanding upper materials of a lasted shoe toe. As herein shown, the wire carrying means is a part of 0r an attachment to a hand tacker, the vnozzle of which is employed for placing the wire and the wire bender is turned about the noz- Zle to wrap the wire around. the stem of the tack as the tack is being driven.

A further feature of the invention is found in a wire tension device mounted to move with the wire carrier in placing the wire around the work. Preferably also the wire tension device moves with the bender in wrapping the wire around the tack. As herein shown the tension device accompanies the bender in its rotary movement and in accordance with a further feature of this invention a wire cutter is interposed in the path of the strand of wire which extends from the bender to the tension device to cut the wire automatically when it has been partially wrapped around the tack.

These and other features of the invention, including certain details of construction and combinations of parts will more fully appear in connection with the followingv description of a preferred embodiment of the invention and will then be pointed out in the claims.

Figure 1 is a perspective view showing the toe portion of ashoe in a bed last-ing machine, the lasting wipers being partially retracted to permit a wire to be carried around the lasted toe by the nozzle of a hand tacker equipped with wire anchoring means embodying this invention; Fig. 2 is a longitudinal sectional view of the tacker and wire anchoring attachment; Fig. 2a is a transverse section on line 2*1L showing a modification; Fig. 3 is a perspective view of the lower end of the apparatus; Fig. L is a perspective detail, and Fig. 5 is a perspective detail from a diEerent angle.

1 indicates a casing of a hand tacker which may be in general construction substantially like that shown in United States Letters Patent No. 500,225, granted on application of Crisp and Judkins June 27, 1893. This casing comprises a cylindrical driver guide having a lateral extension or bracket 2 to which is attached the raceway 4 in which tacks are held and conducted to the driver passage, a gate 5, operated by the wedge bar on the driver plunger 6, being located at the foot of the raceway as shown in the sectional view, Fig. 2. These parts, together of the casing through slots in the plunger to`v` the other side may be the same as in said patent.

Rotatably mounted within the cylindrical driver guide is a sleeve 2O having a slot 22, the lower portionof which is oblique or spiral and in this slot moves a roller stud 24 which projects laterally from the driver plunger 6, see dotted lines Fig. 2. By this arrangement the sleeve 20 is automatically given a partial rotation during the last or tack driving portion of the driver movement. The roller stud may be connected to the driver plunger yieldingly as by a circumferentially movable block 23, Fig. 2, to lessen the shock when the roller enters the spiral portion of the slot in the sleeve.

Attached to the sleeve 20 is an arm 25 which projects through a circumferentially elongated opening in the casing and which is bowed around those portions of the tacker which include the tack feeding devices and has on its lower end a ring 26 provided with a toothed interior face. These teeth mesh with a small pinion 28 which is fastened, Figs. 4 and 2, to or formed integral with a wire twisting sleeve 30 which turns around the nozzle l2 of the tacker. This twisting sleeve has a wire finger 35 by which it engages the wire, assistingto determine its normal position with relation to the tack passage, and compelling the wire to be carried around the stem of the tack when the driver in its descent causes the rotation of said sleeve. The arm 25 carries a tension device 36 between which and the finger 35 the course of the wire is determined and on the lower end of the casing are mounted the open jaws 38 of a wire cutter. This cutter is located in the path of the wire as it is carried around the nozzle by the rotation of armv 25 and sleeve 20. These jaws are pivoted on different centers, as shown in Fig. 3, which are so located that pressure of the wire into the angle between them turns them toward each other in a direction to sever the wire. The lower end of the sleeve 30 is beveled at 40 so that as the sleeve is turned in the directionrof the arrow, Fig. 4, the wire is automatically crowded down toward the shoe. A wire supply holder may be detachably mounted on the tacker. This holder comprises the plate 46 fast to the casing l and having the series of out-turned fingers or flanges. The outer flange 48 supports the coil of wire and has a bead on'its edge which interlocks with the correspond- 'tacker with the wire anchoring attachment may be used, if desired, in the customary wayA toinsert the lasting tacks for securing the upper at the heel as well as an anchor tack in the upper side of the shoe at the toe. The wire is applied to the apparatus by inserting the coil in the holder and passing the end of the wire under the tension device which may be opened to receive it by pressing upon its rear end, Fig. 3. The free end of the wire having been hooked over the finger 35 may then be twisted around the tack by using the tacker 3 as the lasting machine operators are accustomed to use their hand pincers for this purpose. Then the wire is strung or drawn lunder tension about the toe of the shoe, the wipers 41, Fig. l, being backed partially away from the upstanding upper material to permit this placing of the Wire which is very conveniently effected by the nose of the tacker. The wire might come through the tension device from a reel mounted on a stationary support like the frame of the lasting machine if that were preferred. At the second side of the shoe where the tacker is shown in Fig. l, the wire is pulledl tight by means of the tacker and then with the nozzle vresting ony the shoe the driver plunger is forced down to insert the second wire anchoring tack by impact. In the last part Yof this movement the roller stud 24 enters the spiral part of the slot 22, turning the sleeve 20, arm 25 and sleeve 30, and causing the wire finger 35 to carry the wire under tension around the stem of the ingoing tack while the bevel on the end of sleeve 30 forces the wire down toward the shoe. The tack may be left slightly upstanding or may be fully driven, but in either case the twisting sleeve insures that the wire shall be wrapped around the tack stem under its head and close to the surface of the work. As the twisting devices rotate and the tension device 36 with them, although more slowly, the wire between the finger' 35 and the tension engages the cutters 38 and is severed from the supply. The devices are shown as arranged to give to the sleeve 2() a rotary movement of 90 which isl multiplied by theV pinion V28 to give the twisting sleeve 30 a half rotation. This carriesthe end portion of the wire back to the body of the binder.

By the use of this invention in which the wire` is wrapped about the ingoing tack close to the work a shorter and more slender tack can be used than is necessary to use in j hand wiring and such 'a light tack'can adamount of rotation can be given to the wire twisting sleeve if desired by changing the proportions of the gears 26, 28, or extending the spiral portion of the slot 22.

It will be noted that as the apparatus is used to place the wire around the toe, it can be moved to slide the nozzle between the partially backed oif wipers and the upstanding edge of upper that is to be bound in place and the wire will thus be strung around the toe under tension and the finger will place the wire high enough so that it is out of the path of the needle of the sewing machine by which the upper is later fastened permanently to the lip of the insole.
