STEPHEN SNOW, OF EVERETT, MASSACHUSETTS, ASSIGNOR TO PEERLESS MACHINERY COMPANY, OF CHARLESTON, VEST VIRGINIA, AND NEW YORK, N. Y.

LASTINGNNIACHINE.

SPECIFICATION forming part Of Letters Patent NO. 701,411, dated June 3,1902. Application iiled May '7, 1900. Serial No. 15,697. (No model.)

To all whom. t may concern.-

Beit known that I, STEPHEN SNOW, of Everett, county of` Middlesex, State of Massachusetts, have invented an Improvement in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a speciiication, like letters on the drawings representing like parts.

This invention in lasting-machines relates 1o more especially to the toe wiping devices mounted on the jack, my invention being intended as an improvement on the class of machine represented in United States Patent No. 378,446, dated February 28, 1888. In the described patent the toe of the last was acted upon by a leather toe-wiper, the upper edge of which meets the upper of the shoe where it contacts with the top of the last at a point behind the end thereof, said toe-wiper being zo gradually moved forward in contact with the upper on the last, the toe-wiper stretching the upper, and inally passing the toe end of the last and wiping the upper upwardly above the bottom of the last and holding the upper im- 2 5 pinged against the end of the last at and about the edge thereof.

In accordance with my invention I have added to the machine having a toe-wiper of the class described a toe-rest which contacts 3o with the shoe to be lasted and presses the same upon the top ofthe last, the toe-rest moving longitudinallyof the length of the last and followingthe toe-wiper. 4The toe-rest is i adjustable in order that itsposition may be varied to determine the position of the upper edge of the toe-wiper with relation to the upper side of the inner sole laid on the bottom of the last, which during the lasting operation rests on the bottom of the last which is 4o uppermost.

In practice I find that a shoe may be lasted more perfectly and the upper be made to bind the last more closely by the employment of a toe-rest which moves in the direction of the 4.5 length of the last, it following the toe-wiper.

Figure l, in side elevation, represents part of the standard of a lasting-machine, showing a jack containing a toe-wiper and toe-rest embodying my invention, the toe-wiper being in 5o its inoperative position. Fig. 2 is a longitudinal section of part of the devices shown in Fig. l, the toe-wiper being in its operative position. Fig. 3 is a plan view looking into the toe-wiper and upon thetoe-rest. Fig. 4 is a section in the line Fig. l. Fig. 5 is a section in the line 5 5, Fig. 2. Fig. 6 is a section in the line 6 6, and Fig. 71s a detailed View showing the toothed plate d2 and devices cooperative therewith.

The column A, the lever A', the spring .A2 to hold up said lever, the spindle B, revolubly connected with said lever and having at its upper end a head B', ou which is adjustably mounted aheel-carriage Bgand a toe-carriage B3, the means shown for adjusting said toe-carriage on said head, the wiper-carrying levers C, upon the upper ends of which are pivoted the opposite ends of the toe-wiper carrier C', the spring C2, connected with said carrier and to a projection C3 of the said carriage B3, are and may be all as common in this class of lasting-machine, and consequently the named parts are not to be herein claimed.

The central part of the toe-wiper carrier C has jointed to it at c the upper end of a rod c2, having at its lower end a pivot c3, carried by an arm d, extended from a rocking sleeve dm, Fig. 3, surrounding loosely a ixed stud dx, said sleeve being provided with a handpece d4, having a spring-controlled pawl d3. The stud dx has fixed to one end of it a `ratchet-toothed plate d2, which is engaged by the pawl carried by the handpiece, said sleeve, pawl, handpiece, and tooth-plate being common to said patent, the upward movement of the handpiece causing the rod c2 to be lifted to turn the wiper from its inoperative position, Fig. l, into its fully-operative position, Fig. 2. i

Fig. l shows the toe-wiper in its inoperative position, the last at about the ball thereof having been put in contact with the toewiper near its extremities.

In the operation of the machine the toewiper by engagement of the handpiece d4 is turned about the pivots at the upper end of the lever C, andthe upper edge of the toewiper is made to contact with the upper lying on the last at a point behind the toe end of the last, and by a continued movement of the lever the force is sufficient to cause the toewiper to travel bodily, the spring c2 yielding until the toe-Wiper arrives in its fully-operative position, Fig. 2, the toe-Wiper thus stretching and pulling the upper and iitting it to the top of the last between the ball and the toe end of the last, finally holding the upper in contact with the last at and about the junction of the bottom of the last with the sides and toe end thereof.

In accordance with this invention I employ a toe-rest e', which is located inside the toewiper, said rest sustaining the toe end of the last as the toe-wiper completes its stroke in wiping the upper over the toe end of the last. The toe-rest occupies a position between that part of the wiper embracing the toe end of the last and the pivotal point of the toe-wiper.

The wiper meets the upper across the top of the last at a point between the toe-rest and the end of the last and is moved longitudinally over the last toward the toe end thereof. The toe-rest may contact with the upper on the last before or just as the toe-wiper arrives in its eXtreme position, Fig. 2, the upper edge of said toe-wiper in its extreme position standing in alinement with the bottom of the last. The toe-rest has a threaded shank e2, which enters a threaded socket of a suitable support e3, which in the form in which I have herein chosen to show my invention in Figs. l to 3 forms part of the movable rod c2, the said rest being adj ustable to adapt it to the shape of the last and to determine the position to be occupied by the acting edge of the toe-wiper at the end of its stroke. This invention is not, however, limited to supporting said toe-rest on said rod, which is a preferred form, as said rest may be sustained in other ways and yet be within the scope of my invention.

The pin a, holding the heel end of the last, is threaded at its lower end and screws into the threaded tipping post a', adjustable by a worm ft2, engaging a Worm-toothed sector dsx at the lower end of said post in usual manner. The pin is provided with one or more slits a4, which may be engaged by a locking device a6, which may be made to enter any slit and restrain the rotation of said pin.

In order that the spindle B may rise and fall in a straight line under the action of the treadle in positioning the last with relation to the usual lasting devices and also be rotated, I have provided said spindle with opposite grooves b, in which enters a guide-pin b.

In the process of lasting the shoe and spindie have to be revolved, and to provide for this the guide-pin must be withdrawn from the groove. For this purpose I have mounted the pin b' on a carrier, herein represented as composed of a bar b2, connected with a plunger b3, with which cooperates a spring b4, which acts normally to keep the pin in the groove; but the operator may force his knee against the plunger and withdraw the pin whenever he may desire to turn the shoe and spindle,

the pin entering the groove automatically whenever the said groove arrives opposite said pin.

The levers C constitute a movable actuator for the toe-wiper carrier.

I-Iaving fully described my invention, what I claim, and desire to secure by Letters Patent, is-- l. In a lasting-machine, a toe-wiper, and means to move the same when in contact with the upper on the top of the last back of the toe end thereof forwardly toward and to the toe end of the last, said wiper moving in the arc of a circle located between the toe and heel of the last, and a toe-rest movable in the direction of the length of the last during the operation of the toe-wiper, said toe-rest contacting with the upper on the top of the said last back of the toe end thereof.
