SOLE PRESS Filed May 2, 1930 2 Sheets-Sheet I Patented Jan. 5, 1932 JOHN '1. EVANS,

or innrnmiroms, INDIANA SOLE .IERESS Application filed May 2,

This invention relates to repair tools designed primarily for applying half-soles and heels to shoes and the like with adhesives and one feature of the invention is the provision of a device that may be used by a novheel to a shoe.

A further feature of the invention is the provision of forms in connection with the remainder of the device that, when pressure is applied thereon, the parts of the shoe will be protected against injury.

A further feature of the invention is the provision of means for applying pressure to any selected parts of the device for causing the adhesive material to be spread to all parts of the sole or heel to insure a perfect union between the parts of the'shoe and the parts being applied.

A further feature of the invention is the provision of a cushioning means in connection with the sole applying mechanism.

A further feature of the invention is the provision of means for adjusting parts of the device when desired.

Other objects and advantages will be hereinafter more fully set forth and pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application,

Figure 1 is a top plan view of the device applied to use.

Figure 2 is a side elevation thereof.

Figure 3 is a vertical longitudinal sectional view of the device as seen along line 3'8, Fig. 1.

Figure 4 is a plan view of the inner clamping plate for the device.

Figure 5 is a similar View of the outer clamping plate, and,

Figure 6 is a section thereof as seen along line 6-6, Fig. 5.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, the numeral 1 designates a shoe, which may be of any preferred style and size and having an outer sole portion 2, a heel 3 and an inner sole portion 4, to which the outer sole portion is sewed or otherwise attached thereto.

Heretofore, it has been customary to sew 1930. Serial No. 449,137.

or nail a half-sole or heel to the shoe, but in the present instance, the half-sole 5 and the heel 3 are to be secured to the remainder of the shoe by means of any suitable adhesive material, and to make these the shoe proper, they must be applied under strong pressure. a

To this end a'clamping block 6 is provided, which is adapted to fit-over the soleportion of the shoe, with which cooperates a metal clamping plate 7, the upper face of the block 6 and the plate 7, being preferably slightly cupped to conform to the shape of the sole of the shoe. Adapted to snugly fit within'the shoe 1 and being so shaped that the shoe upper will not be injured when pressure is applied, is an inner metal clamping plate 8 with which cooperates a last9-of any suitable construction, said last having an elongated bearing shoulder 10 thereon, with which co-' operatesa clamping bar 11.

The clamping bar 11 preferably extends longitudinally of the shoe and is preferably held in position on the last by means of, a bolt 12, said bolt extending upwardly through the. shoulder '10 and through an elongated slot 13 in thebar 11, so that said bar may be adjusted to difierent forward or rearward positions, as when a half-sole is being attached or a heel is being attached.

Cooperating with the clamping block 6 and the clamping bar 11, are any suitable form of clamps 14 and 15, the clamp 14 being positioned with one terminal engaging the clamping block 6 adjacent the inner end thereof and the opposite terminal engaging the clamping bar 11 at a point in registration with the shoulder 10, when a half-sole is being applied, 15 are located at any suitable point adjacent the outer ends of the block 6 and bar 11. By placing the clamp 14 at the point shown, the greatest pressure is applied at the point on the half-sole receiving the greatest strain when in use, that is, at the inner end of the half-sole and in order to obtain a substantially uniform pressure throughout the extent of the clamping plate 7 a cushion 16 is introduced between the plate 7 and the halfwhile the terminals of the clamp parts adhere to a sole 5, said cushion being constructed of any suitable yielding material.

When a heel is being applied to the shoe,

the bar 11 and plate 8 are adjusted towards the rear portion of the shoe and any suitable form of heel block (not shown) placed to receive the lower extremity of the clamp 14.

y forming the clamping plate 7 slightly cupped, as shown, the proper amount of pres sure will be applied against that portion of the half-sole projecting beyond theedges of the clamping plate 8.

In applying a half-sole or heel in this man-7' ner, it is but necessary to select a half-sole and heel of the proper dimensions to fit the shoe to which they are to be applied, so that any person, whether skilled or not, may apply the clamping mechanism and secure the half-sole and heel to the shoe, as it is then merely the applying of proper pressure to complete the operations.

What I claim is:

Means for securing parts to a shoe withan adhesive, comprising a clamping block adapted to engage the exterior of a shoe, a

last adapted to be inserted in the shoe, a shoulder on sa-id last, a flat clamping bar adapted to rest on said shoulder and extending lengthwise of the shoe with its ends projecting beyond said shoulder in each direc tion, said bar having an elongated slot therethrough, a bolt extending through said shoulder and through said slot, in the bar for adjustably attaching the bar to the last, and 354 clamps adapted to engage said block and bar at any point between the ends thereof for forcing said block and last against interposed parts. i

In testimony whereofl I have hereuntoset myohand on this the 22nd day of April, A. D.

JOHN T. EVANS.
