LASTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 564,152, dated. July 14, 1896.

Application filed August 31, 1893. Serial No. 484,450- (No model.)

To all whom it may concern.-

Be it known that I, CHARLES H. KELLEY, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Lasting-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its objectan im provement in lasting-jacks, by means of which the shoe is not only held in position while the upper is being secured in place by tacks or other securing means, but which shall also serve to properly smooth and press the upper into position prior to the securing of the upper in place; and it consists in a device constructed as hereinafter set forth, and the novel features of which are pointed out in the claims which are appended hereto.

In the accompanying drawings, to which reference is made in the following description, I have shown a device embodying my invention.

In said drawings, Figure 1 is a side elevation, and Fig. 2 is a plan view looking down from line 2 2 of Fig. 1.

My device may be employed either in connection with some of the well-known machines for lasting shoes inwhich the upper will be secured in place by tacks or other securing means in the operation of the machine, or it maybe employed simply to effect the lasting of the shoe, that is, to properly smooth and press the upper over the last, and the operator may then secure the upper in place by hand.

The supporting-bed, which is shown at A, may obviously be varied in form as desired, or if the device be employed in connection with a machine for securing the upper in place the bed A may be-omitted, the base piece B being applied directly to a portion of the jack-supporting mechanism of the machine.

The bed A is preferably provided with pins 0, which fit holes in the base 13, and which afford a means of quickly and accurately placing the base on the bed and securing it thereon. At one end of the base Bis secured a post (I, said post being set in a slot 6, formed lengthwise of the part B to permit of the adjustment of the post to accommodate lasts of different sizes. To the post dis pivoted the heel-rest f, which is provided on top with a pin adapted to project into a socket in the last in the well-known manner. At the other end of the base B a post g is secured in the same manner as is the post d. Upon the post 9 is mounted the pivoted toe-rest h. The upper portion of the post 9 is adapted to be raised or lowered and seen red in a given position, as shown.-

The construction of the heel and toe rests is old and well known and will not require a more detailed description. v

To the base of the post is secured, by means of a bolt j, the part k, which is provided at its outer end with a post or stud Z, upon which is pivoted the laterally-extending arms m n.

. The part 75 may, if desired, be formed integral with the base B. These arms are made preferably of spring metal, so that they may yield slightly. They are of the shape shown in Fig. 2, being curved slightly outwardly to correspond somewhat with the curve of the sides of the last. To the arms m n are secured, by means of 'a clamping-strip w or in any suitable manner, a series of vertical springarms 19. These arms extend upwardly and are preferably curved, curving outwardly slightly and then inwardly at their upper ends, where they are rounded or turned back slightly, so that as they engage the upper they will press and bear against it without danger of defacing or tearing it.

The number of the vertical arms employed may be varied, but I prefer to employ as many as four on each side. I prefer also to employ a spring-arm g, which is fast at its lower end to the upper portion of the post g, and which at its upper end engages the upper at the toe of the shoe, but I do not consider this arm as essential to the operation of my device, and it may be omitted, if desired.

On one of the arms m n I pivot, as shown at r, a latch s, which extends across to the opposite laterally-extending arm and is provided at its free end with a shoulder or hook, (shown at t,) which engages said opposite arm when the lateral arms are closed, and which serves to hold said arms in a closed position. By raising this latch the arms on a will spring apart or may be thrown apart, freeing the vertical arms 1) from the shoe.

The operation of the device is simple. The operator, after assembling the parts of the shoe on the last, places the heel of the last on the heel-rest, the rest being then swung back on its pivot out of the vertical position. The last is then brought forward until the upper ends of the vertical spring-arms p bear on the sides of the upper. The arms m n are then closed or brought together and are secured in that position by the latch s. The operator then forces the last downwardly until the toe of the shoe bears firmly on the toerest. In doing this the sides of the upper are spread and smoothed out by the rubbing and pressing contact of the ends of the sprin garms 19, and the upper is drawn tightly and smoothly into position on the last. The operator may then readily draw in the edge of the upper over the insole and secure it in place, or the edge of the upper may be drawn in and properly placed and the jack put into a tacking-machine or similar device and the upper secured in place by the operation of the machine. To remove the shoe, it is only necessary to raise or trip the latch 3, allowing the arms m n to spring apart, after which the shoe may be readily removed.

The device is simple, speedy in its operation, and effective. If, however, in any case it does not operate to perfectly smooth and bring the upper into position, the operator may readily see where the defect is and may quickly remove it by drawing the upper into place with his pincers, when the arms 1) will operate to hold it securely in place while it is being tacked or otherwise fastened.

hen the device is employed in connection with a tacking-machine, the speed with which it maybe operated, both in lasting the shoe and in removing the shoe after it has been lasted, is of great importance.

hat I claim is- 1. The combination in a lasting-jack with the last-supports of arms located on opposite sides of the last-supports, and pivoted at one end adjacent to one of said supports to enable them to be swung horizontally toward and from a last mounted on the said lastsupports, a series of vertical spring-arms rigidly secured to each of said lateral arms and means for securing said lateral arms in their closed position, substantially as and for the purposes set forth.

2. The combination in a lasting-jack with the arms pivoted at one end thereof as described and each having a series of vertical spring-arms rigidly affixed thereto of a latch secured to one of said lateral arms and adapted to engage the other lateral arm for the purpose of holding the arms in their closed position, substantially as set forth.

A lasting-jack provided with arms pivoted at one end thereof as described and each having rigidly applied thereto a series of vertical spring-arms for engaging the sides of the upper, means for holding said arms in their closed position; and a vertical springarm for engaging the toe of the upper, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
