Specification ofLetters Patent.

Patented Mar. 5, 1912.

Application filed January 27, 1911. Serial No. 605,017.

To all whom t may concern: Y

Be it known that I, Louis G. FREEMAN, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented an Improvement in Insole and Lasting Tack Fullers and Toe-Wire Removers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. Y

This inventionis a machine for pulling the insole and side tacks and removing the toe-lasting wire usually employed inthe process of lasting welt innersoles.

Innersoles are usually secured to the last by three or more holding tacks located as to hold the innersole in place on the last and usually driven down hard into the last, and quite a number of tacks are driven along the side at the points where displacement of the upper would be most apt to occur, to insure the retaining thereof in proper lasted relation to the innersole.

My invention provides cooperative means for pulling these two sets of tacks, including the anchor tacks for the toe-lasting wire, and in conjunction therewith provides means whereby the toe-lasting wire can be quickly and easily removed.

A prominent characteristic of the invention is the special juxtaposition of parts to accomplish these functions, whereby the several results come about virtually as component parts of a single operation.

The invention provides a novel form and arrangement of power controlled gripper for the toe-lasting wire, an especially effective arrangement of side tack-puller, and other improvements in detail, which will hereinafter more fully appear.

In the drawings, in which I have shown a preferred embodiment of my invention, Figure 1 is a side elevation of the machine; Fig. 2 is a plan view thereof; Fig. 3 is a front elevation; Fig. 4 is a sectional side elevation on line 4 -4 of Fig. 2, showing details of the toe-wire gripper; Figs. 5 and 6 are side and front elevations respectively of the side tack puller gage; Figs. 7 and 8 are side and front elevations respectively of the insole tack-puller gage; Figs. 9 and 10 show, enlarged, the side tack-pulling tool in V"side and front elevation respectively; and Figs. 11 and 12 show, also enlarged, in side and front elevation respectively the innersole tack-pulling tool; and Figs. 13-16 illustrate the operative positions of the mechanism when at work, Fig. 13 showing i'n side elevation the side tack puller engaging a tack, Fig. 14 the same in front elevation, Fig. 15 the insole tack puller in front elevation, and Fig. 16 a top plan view illustrating a capability of pulling the wire upward by means of the member 25 while the shoe 1s strained downward to bring one or 3 the other of the end tacks into position to be knocked out or pulled out by an adjacent tack puller.

In the machine of the drawings, I have shown two laterally spaced-apart tack moving tools carried on reciprocating arms 1, 2, the tack-engaging fingers or tools proper 3, 4 carried by these arms having special form adapted for the side tack-pulling and innersole tack-pulling respectively, as later described. The reciprocating arms 1, 2

are similarly mounted, each being suspended intermediate its length on short`oscillating links 5 from the frame head 6 and being actuated by eccentrics 7, 8 on a driver v shaft 9 actuated by driving pulley 10. This eccentric movement in connection with the `link suspension of the arms at 5, will cause vthey tack-engaging points of the tools to traverse a cycloidal path for digging and pulling the tacks. The two eccentrics 7 and 8 are shown as oppositely mounted on the shaft 9, so that as either tool is advanced the other will be retracted.

The side tack-pulling tool 3 and the innersole tack-pulling tool 4 are arranged to coact with yielding backing posts or gages 12, 13 respectively. These posts or gages are slidably mounted in bearings 14, 15- at the front end of the frame head 6 and are normally urged to a lower limit of movement as by springs 16 fixed to the fra-me head, engaging collars 17 adjustably secured to said gages or posts by screws 18, the limit of downward movement of said posts being determined by the engagement of the collars 17 with the top of the frame head in whatever position the posts are mounted relative to said collars. The gages 12, 13 are enlarged and forked at their lower extremities, as shown at 19, 20, to permit the movement of the operative ends of the tools 8, 4 therethrough, and the end of gage 12 along which the edge of the shoe is adapted to be engaged and slid as shown in Fig. 1, has its end cut away so that the shoe form may more easily and properly slide along, and

kept in substantial longitudinal alinement with the direction of the pulling devices for the pulling of the several side tacks, it being only necessary then for the operator to move the shoe in the proper lengthwise positions to pull the tacks. The other post or gage 13 has its forked bottom rounded as shown at 23, this being adapted to engage the insole between the welt seams to enable the insole tack puller 4 to dig out the insole tacks as described in Patent No. 923,828,

issued to me June 8, 1909. The side tack puller 3, operated in like manner as the insole tack puller, has a similar orbital path of movement, as more fully set forth in said patent, yto .engage under the head and lift the tack by a nearly vertical movement, this side tack puller having its prime distinction in the special form of its backing post or gage 12 which coperates therewith and also has relation to the insole tack puller as now to be explained. It is thus apparent that the successive side tacks canvbe quickly removed by the tool 3, the shoe being slid along in engagement with the gage 12, and keptin proper position thereby for operation on the several side tacks, and, when desired, as the several insole tacks come adjacent the insole tack puller, the operator is enabled to pull said insole tacks by the tool `4, an adjacent part of the sole being then pressed against the gage 13. @ne pulling device is going back while the other is coming forward, thereby facilitating rapid pulling and the ready manipulation of the shoe before one or the other of the pulling devices with great freedom and without confusion or liability of injuring the work.

Fixed to and projecting from the forward i end of the frame head 6 intermediate and preferably somewhat above the two pullers, is a fixed, lower jaw 24 of a toe-lasting wire gripper, extending beyond or forward of the tack-pullers and slightly inclined downward from the horizontal to coperate to the best advantage with the rest of the niachiiie in dislodging specially hard and ob stinate wires and their end-holding tacks. This lower jaw 24 has a sharp beak 25 to be forced underneath the wire at the toe of the shoe, to coperate with a movable jaw 26, pivoted at r27 to the frame support and normally urged toward closed position byl roller 29 on the end of a lever arm 30 pivoted at 31 to a projection upstanding from theframe, this arm being actuated by eng'agement of a roller 32 on its inner end by a cam 33 fixedl on a shaft 34 suitably journaled in the frame head. This shaft is driven by any suit-able means, as by a pulley 35 and a belt 36 from a pulley 37 on the driving shaft 9. The cam 33 has a relatively long cut-away port-ion 33 to permit the jaws to remain closed about two-thirds of a revolution ofthe cam, so as to give sufficient time to enable the operator to manipulate the shoe, if required or desired, to bring either the wire or wire-holding tacks into coperation with the adjacent puller tool 3 or 4.

The gripper is so located and its operation preferably timed, with reference to the two tack pullers, to permit the operator with the utmost celerit-y to remove the wire and the two anchor tacks which hold its opposite ends, and, as already explained, the two tack digging and pulling tools and their operating mechanism and adjacent parts, are so located with reference to each other as to permit the operator to remove all the tacks progressively and with eXtreme speed, the respective pullers being preferably separated sufliciently and also operating alternately so that there is no possibility of their both engaging' the shoe at once, butV on the contrary, as constructed, they permit the operator at will to use either to the best advantage and yet to shift instantly to the other if desired, and to bring either into coperation with the wire gripper whenever desired. For example, when a toe wire is to be removed, the operator catches the wire w over the beak 25 or the latter is dug under the wire to permit the wire to be gripped and the shoe is then instantly pulled or jerked downward by the operator in that direction which will bring the obstinate wire-holding tack in position to be pulled or knocked out by the adjacent pulling device.

In Fig. 16 the range of lateral movement required of the shoe is indicated at s and s to bring the left hand wire-end tack or the right hand tack as the case may be into position so that when the shoe is pulled down to bring its toe wire taut the adjacent pulling tool will strike the taut wire or the tack and thereby dislodge the latter and free the wire.

The respective tack pullers and gripper may be spaced apart widely or narrowly and preferably also the pullers operate at a high speed, the usual skilled workman becoming quickly expert inhandling the shoe in each of its positions and in bringing either/of the three tools to the aid of the other or others whenever required or desired, so that a shoe l spans the forked end of the tack puller rest or gage 12 as important, because it makes it practically impossible for the tool 3 to gouge the welt ridge while said gage is sliding along the same and said tool is operating between the forked sides thereof to pull the side tacks. The stationary member 24 of the wire gripper projects slightly so as to permitthe operator to use the same to dig out a particularly obstinate wire (or, for that matter, a tack if desired) when buried in the welt seam.

I believe myself to be the first inventor of a twin tack puller having tools adapted to co-act as set forth and particularly also in conjunction with a toe-wire gripper disposed for co-action therewith as explained.

yWhile I prefer the form of reciprocating tool, moving in an orbital path, as herein shown, I do not limit myself to this particular tool and operating mechanism therefor except as set forth in the claims.
