CARL S. NORDEN, OF WAKEFIELD, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATER-SON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

T 0 cl? whom it may concern."

Be it .known that I, CARL S. NORDEN, a citizen of the United. States, residing at Wakefield, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Lasting-Machines, 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 has for its object to provide improvements by which the toes of shoes can be more satisfactorily and more expeditiously lasted than heretofore.

An important feature of this invention consists in an auxiliary device to draw the upper tight near the ends of wipers in a toe lasting apparatus. Wit-h apparatus as heretofore used this is one of the most difficult portions of the shoe to last, particularly on high toed lasts, because the wipers are less efficient near their ends than they are at the middle and corners of the toe and the upper forming and stretching action required is more than that which the wipers unaided can usually produce. This feature of the invention is embodied in grippers that are adapted to span the shoe and seize the upper at both sides of the toe and pull it adjacent to the ends of the wipers. The grippers can be caused to hold the upper under tension while the end portions of the wipers lay it over the last bot-tom into position to be fastened. The grippers comprise, in addition to their jaws and provision for closing and opening them, a fulcrum or rest relatively to which they can be rocked to pull the upper. A carrier for the grippers is provided at one side of the machine and movable to transfer the grippers to and from working position. In this carrier the grippers may be fulcrumed. In addition to its function as a gripper support the carrier is, in accordance with other features of this invention, made to serve as a holddown for clamping the last upon the toe rest. The holddown also advantageously has a foot to clamp the upper at the end of the toe in outspread position on the wipers. In apparatus of the type herein shown in which Specification of Letters Patent.

LASTING-MACHINE.

Serial No. 614,621.

the wipers and the last haVe'a relative vertical movement to rub the upper up the sides of the last the downhold may advantageously have an abutment to engage the wipers and limit such relative movement when the wipers are in a plane to close over the feather of the insole. This avoids such excessive movement as carries the wipers too high and allows the upper to slip and loosen back down the sides of the last before it is overlaid. These and other features of the invention, including certain details of construction and combinations of parts will more fully appear from the detailed description and will then be pointed out in the claims.

Figure 1 is a perspective view of a toe lasting apparatus embodying the present invention; Fig. 2 is a longitudinal section; Fig. 3 shows the same devices differently arranged.

The machine comprises a frame or support 2 in which a toe rest 4 is mounted for vertical movement and a toe lasting mechanism comprising wipers 5, connected with an operating handle 6, which are arranged for vertical movement altogether to cause the wipers to rub the upper up the sides of the last to the edge of the last bottom. The wipers are then advanced toward the heel and closed inwardly at the opposite sides of the toe to lay the upper over the feat-her of the insole and against the channel 11p where it is usually secured by a binder. These parts are or may be substantially as they are in the well known commercial No. 5 lasting machine. Alternatively the last may be depressed with relation to the wipers to efiect the rubbing'action of the wipers upon the upper on the side faces of the shoes as in the commercial type of lasting machine known as the Chase laster.

A bracket 10 attached to the rear side of the machine guides a vertically movable rod 11 or post, the lower end of which is connected to a treadle 12 by which the rod and the parts attached thereto may be drawn down to hold it in depressed condition with more or less force by the foot of the operator. Rotatably attached to the upper end of this rod is the hub or arm 1 1 and a torsion spring 15 has one end attached to the bracket and the other attached to the arm for turning the arm normally backwardly to carry it and its attached parts to a' position at the rear of the machine where they will be out of the way of the operator in inserting and removing the shoe. The bracket has a finger 16 to limit the movement of the arm. The arm H serves as a carrier for a pivoted stem 20 which is held in a normal angular position by a spring 22. The lower end of the stem supports the foot 24 shown best in Figs. 2 and 3 which has a contact member 25 and a rearwardly eX- tending arm in which is adjustably mounted a second contact member 26. The contact member 26 is adapted to serve as in Figs. 1 and 2 as a holddown to clamp the shoe down upon the toe rest or, if the machine be a Chase laster, to depress the last and the toe rest with relation to the wipers. In the machine shown the clamping of the shoe down upon the toe rest is desirable in order to hold the shoe from being lifted by the rearwardly rubbing action of the wipers as they are raised in wiping contact with the upper along the sides of the shoe.

The contact member 25 is adapted to be positioned over the wipers at the middle of the toe to limit the relative vertical movement of the wipers and the last and arrest that movement when the wipers are in a plane to lay the upper over the feather of the insole. The provision of this contact member prevents the wipers from being unintentionally raised high enough to lose their frictional hold upon the upper and allow the upper which they have wiped up to slack back before it is overlaid. The upper at the end of the toe will be outspread over the wipers, as shown in the use of these machines, and when the wipers are raised the upper will be clamped or gripped be tween the top face of the wipers and the contact member 25. Said contact member then serves as a retarder to restrain or retard the slipping of the upper over the wipers as the wipers are advanced and closed for laying the upper in lasted position. The

contact member 25 may be for this purpose of any desired lateral extent and of appropriate shape to serve this upper retarding function. The lower or stock engaging face of the'member 25 may be shaped as heretofore proposed for applying a different degree of clamping force to the upper at the middle and corners of the toe. Conveniently the lower face of the retarder will be cut away slightly at the middle of the toe and will be formed to apply a maximum retarding force at the corners of the toe. The object of this formation is to effect stretch ing of the upper to the desired extent at the corners of the toe without liability of over pulling it at the middle of the toe and thereby bowing or curving the tip seam.

operated by one hand of the workman. As :shown, the inner jaws of the grippers, that is, the jaws which engage the lining side of the upper stock, are formed on a single head 32 which is rigid in the direction of -the width of the shoe. The outer jaws are pivoted at 33 to the head 32 and are actuated by a wedge 34 carried on the end of the operating lever 35, the head 32 being rigidly attached to the upper one 36. A spring 37 opens the jaws when permitted to do so. The grippers are intended to be positioned to seize the upper at the two sides of the toe at or adjacent to the ends of the wipers and to pull the upper at this por tion of the shoe where the action of the wipers is least effective. The grippers may hold the upper under tension while the wipers close for overlaying it. The rigid head 32 carrying the inner jaws holds the upper out while the Wipers close under the grippers in overlaying the upper, thereby securing an effectual stretching of the upper at the ends of the wipers. Obviously the grippers can be caused to seize and pull different sections of the upper along the sides of the toe to draw it into condition to be overlaid by the wipers. The provision of a plurality of recesses in the lever 36 facilitates this use.

The devices above described are capable ,of use not only as above indicated, but as shown in Fig. 3. In this use the contact members 25 and 26 of the foot 2& are relatively adjusted into the same plane and are both caused to engage the insole over the ball of the last. The grippers are turned around to present their handle ends at the 5 rear of the wipers and their gripping jaws infront of the stem 20. lVhen the parts are thus arranged the grippers are used in substantially the same manner as that above described for pulling the upper at the sides of the toe at one or at a plurality of points lengthwise of the shoe and holding the upper under tension while the wipers overlay it. The capacity of the apparatus for arrangement in the two relations above described adapts it for the convenience or preferences of different operators.

In the lasting operation as carried on with the described apparatus the shoe is placed upon the toe rest and the upper at the end of the shoe outspread over the wipers. The arm 14 is then swung away from the finger 16 toposition the foot 24 over the last. If the parts are arranged as in Figs. 1 and 2 the contact member 26 is positioned just back of the insole lip and this brings the member 25 over the wipers, then the wipers and the last are relatively moved vertically either by lifting the wipers or by depressing the last by means of the treadle 12. hen the right vertical relation of the wipers and the last has been reached this movement is stopped and the toe portion of the upper is gripped or clamped against the wipers by the retarder member 25. With the parts in this position the wipers can be advanced to overlay the upper while the pressure of the retarder upon the upper is varied by the foot of the operator. Before advancing the wipers to overlie the upper the grippers will be manipulated to seize the upper at the sides of the toe at or adjacent to the ends of the wipers and the grippers will be rocked about the fulcrum point 30 to pull and stretch the upper tightly about the last and hold it while the wipers are closed under the grippers, the rigid head 32 of the grippers holding the edge of the upper out while the wipers close under the grippers. The grippers and the end portions of the retarder cooperate respectively with the wipers to obtain more stretching or pulling of the upper at the sides and at the corners of the toe while excessive stretching of the upper at the tip end of the tee is avoided by the formation of the lower face of the retarder. If the arrangement is that shown in Fig. 3 the contact members 25, 26 serve slmply as a holddown for the last depressor to clamp or depress the last upon the toe rest and the grippers are used in the manner above described for stretching the upper preparatory to the operation of the wipers and cooperate with the wipers in laying the upper over the last bottom under tension at the sides of the toe. When the upper has been overlaid preparatory to fastening it the grippers are released from the upper and the treadle 12 is allowed to rise in response to the upper expansion of the spring 15, the torsion of the spring swings the carrier 14L and its attached parts backwardly away from the shoe until this movement is arrested by engagement of the arm 14 with the finger 16.
