EUGENE L. KEYES, OF BOSTON, MASSACHUSETTS, ASSIGNOB TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Application filed April 28, 1911.

To all whom it may concern:

Be it known that I, EUGENE L. Knvns, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Apparatus for Use in Lasting Toes, 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 lasting apparatus and particularly to apparatus designed for use by a hand workman to facilitate the listing and fastening of the toe portion of a s 0e.

This invention is particularly useful in the manufacture of turn shoes, although it is capable of use also in making welt shoes.

The object of the invention is to provide means to assist the operator in binding the toe portion of the shoe in lasted position.

An important feature of the invention consists in means constructed and arranged for use by ahand laster for holding a toe binding wire under tension in position to bind the upper in lasted position as the lasting operation proceeds about the toe. This is shown as embodied in a wire guiding arm mounted for movement of its wire delivering end around the toe portion of a shoe from one side of the shoe to the other as the toe of the shoe is being progressively lasted, and means to cause said wiring arm to hold the wire under tension at difierent points in the path.

Other features of the invention, including certain details of construction and combinations of parts will appear in connection with the following description of an illustrated embodiment of the invention and will then be pointed out in the claims.

Figure 1 is a side elevation; Fig. 2 is a perspective view showing the toe portion of the shoe during the progress of the lasting on the first side of the toe; Fig. 3 is a perspective view showing the toe portion of the shoe during the progress of the lasting on the second side and illustrating in dotted lines the movement of the wire guide for wrapping the wire around the anchor tacks.

The illustrated apparatus comprises a lasting jack having a base to rest upon the floor, a column 2 tubular at its upper end to receive in vertically adjusted position a stem Specification of Letters Patent.

4 on the upper end of which is formed a circular disk shaped head 5. On a bracket 6 1s a similar disk shaped member which is clamped frictionally upon the member 5 by a screw upon which is a wing nut 7. On the left hand end of the bracket 6 is a bearing for a sleeve stem of the jack base 8, said stem having on its lower end a ratchet 10 with which cooperates a locking pawl, not shown, to restrain the jack from rotation or to hold it against rotation in one direction. From one side of the jack base 8 projects a curved horn 14 upon which is adjustably held the sleeved lower end of the toe post 15. Upon an oppositely projecting horn 16 of the base is pivoted a heel post member 18 havmg; a last pin 20 and having a forwardly directed arm pulled upon by a spring 22 that extends into the stem of the base. The spring holds the last pin tipped forwardly and when the shoe is on the last holds the toe portion of the shoe firmly down upon the toe post 15. The column 2 has bearing in a bracket 24 that is adapted to be fastened to a work bench 25.

The column 2 is embraced by a split sleeve onthe lower end of a bracket 30 which is frictionally clamped thereon to resist turning movement by a screw having an operating handle 32, said arm resting down upon a collar 33 which is adjustable on the column 2 to vary the height of bracket 30. The bracket trends upwardly and at its free end has a horizontally projecting portion to which is clamped in horizontally adjusted position a foot 35 having a slot through which the adjusting bolts 34: extend into the bracket. The foot 35' has a vertical bearing for the lower end of a post 36, said post having a collar 38 to rest on the foot and the foot having a handled bolt 39 by which to hold the'post 36 frictionally in the pos1- tion to which it may be turned in the use ofthe apparatus. At the upper end of the post is mounted the wiring arm 40, the connection providing for a turning movement of the wiring arm up and down and for frictionally holding said arm in adjusted position. The arm comprises a sleeve member which is directly connected to the post and a rod member sliding endwise in the sleeve member and having a stud 42 in a slot in the sleeve member to limit the sliding movement and to restrain the parts from relative turning movement. A spring ll holds the rod member normally within the sleeve member. The rod member has a tapering nozzle-like free end and a Wire passage leading from its end backwardly to a point near the sleeve member. The post 36 supports by a sleeve the spool holder or reel 45 and a tension device 46 through which the wire passes from the spool upwardly into the passage of the wiring arm and thence out from the tapering nozzle.

It will be noted that the connection of the Wiring arm to the post is a frictional joint and that the post turns in the foot 35 against a friction determined by the handle 36 and again the bracket 30 turns on the column 2 against a frictional resistance. This provides a flexible supporting means for the Wiring arm adapted to permit the arm to be positioned as required in the wiring operation and to maintain the arm in any position to which it is moved. In the use of the ap paratus a shoe is applied to the last pin 20 and held in position upon the toe post 15 by the action of the spring 22. The shoe may be pulled over and the sides and the heel seat lasted after having been applied to the jack or the shoe may be prepared for the toe lasting operation in any other desired manner. In beginning the toe lasting operation the workman swings the wiring arm downwardly to the shoe andanchors the free end of the wire to a tack in the right hand side of the shoe. He then swings the wiring apparatus to position the wiring arm about as shown in Fig. 2 with the wire under tension between the tack and the end of the Wiring arm and pressing against the upper along the side of the toe. The friction joints in the apparatus may be adequate to hold the wiring arm with the wire under suflicient tension in this position or the tension may be supplemented or maintained by the left hand of the workman on the wiring arm. The workman now with his hand pincers or other lasting devices pulls the upper into lasted position and crimps or plaits it, beginning preferably at the end of the toe and working backwardly along the right hand side and causing the wire to bind the upper with suiiicient force to hold it in its lasted position as the operation proceeds from theend of the toe toward the anchor tack. When the lasting of this side of the toe is completed the workman turns the jack about the axis of the post 4: and he turns the wiring apparatus about the axis of the column'2 as may be necessary to cause the shoe and the wiring arm to move progressively from the relative position shown in Fig. 2 to the relative position shown in Fig. 3, meanwhile lasting the end and the left hand side of the toe and laying his plaits toward the toe on the left hand side like the plaitswere laid toward the toe on the right hand side. With his hand the workman then hooks the wire over a tack on the left hand side and manipulates the wiring arm to wrap the wire around the tack and secure it. If the workman be left handed the shoe support and the wiring apparatus may be both turned about the axis of the column 2 into a position at the right hand side of that column in the drawings and then the lasting operation will begin with the left hand side of the shoe and proceed around the toe to the opposite side.

That improvement in methods of making shoes herein disclosed is not claimed in this application but constitutes the subjectmatter of a divisional application, Ser. No. 87Q,81l, filed Nov. 7, 1914.
