SPECIFIGATION forming part of Letters Patent No. 649,879, dated May 15, 1900.

Application filed August 24, 1899. Serial No. 728623. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM. T. SHEILL, a

tizen of the United States, residing at Do- )it, county of IVayne, State of Michigan,

.ve invented a certain new and useful Imovement in Relasting-Wlachines; and I de are the following to be afull, clear, and ex- -.t description of the invention, such as will iable others skilled in the art to which it ertains to make and use the same, refernce being had to the accompanying draw- Jgs, which form a part of this specification.

This invention relates to a shoe-last inserter,and has for its object an improved ma- .hine adapted to insert a last in a turned shoe.

In that class of shoes which are known as turned shoes it is necessary to insert a last in the shoe after it has been partially made wrong side out and turned right side out, and it has been found very difficult to "orce the last into the toe of the shoe, so that .t will fully fill the shoe out to its proper shape. The machine which contains this invention overcomes the ditiiculty and enables the workman to force a last into the shoe without pulling or stretching the upper of the shoe in any way to destroy its proper shape.

The machine is intended to be used especially with jointed lasts; but the principle employed may be used with the ordinary unjointed last equally as well as with the jointed last.

In the drawings, Figure lshows a machine with a shoe in place preparatory to forcing the last into the shoe. Fig. 2 is a plan View. Fig. 3 is a side elevation showing the last in the position on the machine as it would appear were it placed on the machine Without the shoe. Fig. 4 shows the machine adapted for use with an unjointed last. Fig. 5 shows an unjointed last in position on the machine. The last in this case is provided with a hole leading into the under side of it at the heel part of the last. Fig. 6 is a cross-section of the machine.

A indicates the frame of the machine; B, the tubular part of the frame; 0, a toe-rest on the table. At that part of the frame over which the heel of the shoe rests and below the tubular part of the frame there is a clamp consisting of a movable jaw 61, a fixed jaw 19, and means for forcing the movable jawtoward the fixed jaw. As shown in the drawings, the means employed is a cam-lever (1', one end of which is mounted on a rock-shaft c, which bears in brackets that extend from the fixed jaw and one end of which, 01, is connected by a link to a foot-lever d". The cam 61 presses against the movable jaw and presses the movable jaw toward the fixed jaw. A sliding frame 6 rests in supportingbrackets e, that project from the table-frame, and this sliding frame e is provided at the end which lies above the clamp with a hook h. The hook it rises above the surface of the table and is adapted to engage against an opposing part of the last. When the jointed last is used, the hook 71 has the shape shown in Fig. 1 and engages against the back or hinge end of the toe part of the last.

When an unjointed last is used, the hook it may take the shape of apin rising straight from the sliding plate e, as is shown at h of Fig. 5, or it may take the form of a gooseneck hook, (shown at h in Fig. at.) In either of the latter forms the pin or hook engages in a hole in the last. The frame 6 is normally held back, with the hook it behind the clamp, and it is held in this position by a spring It. To the forward end of the frame is engaged a chain it, that extends over the sheave 70 to a foot-lever 7t. A catch d on the foot-lever 61 engages under a toothed standard (Z and a catch it on the foot-lever 70 engages under a toothed standard it.

In operation the heel part of the sole of the shoe is left without fastening it to the upper when the shoe is sewed, and the rear part of the sole, loose from the upper, is bent downward and engaged between the jaws to and b of the clamp. The last is inserted in the shoe either before the sole is clamped in the jaws or afterward, and the last is pushed into the shoe until the hook can engage the last properly. If a jointed last is used, the last is pushed into the shoe until the hook can engage behind the toe part of the last. If an unjointed last is used, it is provided with a hole that extends vertically into the heel part of the last either through it or from above into it or from below into it, and the hook 7t or 762 engaged in the hole. After the sliding part of the frame has been engaged to the last the last is pulled forward by means of the sliding frame 6, which is actuated by the foot-lever 10 The shoe is held againstthe forward pressure of the last, because the heel part of the sole of the shoe is heldbetween the jaws a and b of the clamp.

What I claim is 1. In alast-inserting machine, in combination with means for grasping and holding the sole of a shoe, a hook adapted to engage the last, and means for pressing the last forward into the shoe, substantially as described.

2. In a machine for inserting a last in a shoe, in combination with a support for the shoe, a clamp arranged to grasp the heel part of the sole, a hook arranged to grasp the last, and means whereby the hook is actutated to push the last forward, substantially as described.

3. In a machine for inserting a last in a shoe, in combination with a support for the shoe, a clamp arranged to grasp the heel part of the shoe-sole,- means adapted to engage the last, and means whereby the last is forced into the shoe, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
