1 Claim. -(Cl. 1233) This invention relates to shoe repair devices and more particularly to a device for use in applying half-soles to shoes.

A primary object of the present invention is to provide a device of this character which will permit the repairing of shoes in such a manner that the shoe will be pressed back into its original shape; the cementing of the shank end of halfsoles to the shank of the shoe instead of-nailing said end as is now the general practice; and which finally will permit the repair man to properly shape the shoe during the course of repair, in the region of the shank thereof so as to provide the necessary metatarsal support.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure l is a top plan view of the device.

Figure 2 is a side elevational view thereof.

Figure 3 is an end elevational view of the device.

Figure 4 is a detail view partly in section and partly in elevation showing a shank plate and a supporting standard therefor.

Figure 5 is a detail sectional view showing the universal connection between a pressure plate and a lever therefor, and

Figure 6 is a plan view of a last plate.

Referring to the drawings by reference numerals it will be seen that in the preferred embodiment thereof the device comprises a base or platform In to which adjacent opposite ends thereof are secured base or attaching plates II and I2 respectively. Rising from the plate II is a pair of integral spaced posts I3 provided with rows of vertically spaced openings whereby through the medium of a pivot pin I4 a lever I5 at one end may have an adjustable pivotal connection with the posts I3.

Rising from the plate I2 is a pair of integral standards or posts It between which the free end of the lever I5 worlm. The lever I5 at said free end is provided with a lateral tooth I'I cooperable with ratchet teeth I8 formed on the inner face of one of the standards I6 for securing the lever I5 at the desired adjustment. Secured to and rising from the base II] at about the center thereof is a pedestal I9 which supports a last plate 20 detachably connected to the pedestal through themedium of interengaging sockets and pins indicated generally at 2I.

Relative to the last plate 20 it will be understood that the repair man will maintain in stock any number of such plates varying in size and shape for selective use according to the size and shape or style of shoe being repaired.

In all forms thereof the last plate 20, asclearly. shown in Figure 6, willbe characterized by asuitable depression 22 to the shape of which theinsole and filler are molded due to the external pressure applied through the medium of a, pressure plate 23, the under face of which pressure plate is suit: ably shaped to insure the application of, proper pressure as will insure a proper shaping of the repaired shoe at the shank thereof;

The pressure plate 23 is provided at the top side thereof with a socket 24 for receiving a ball 25 on one end of a stem 26 that has a portion thereof extending through a suitable opening provided therefor in the lever I5.

The ball 25 is retained in its socket through the medium of a plate 21 suitablyapertured to accommodate the shank 26 and secured tothe presser plate 23 by set screws or other suitable fastening means 28.

The shank 26 is secured in place on the lever I5 through the medium of a plate 29 secured tothe lever by screws or other suitable fastening means 30. The plate 29', it will be noted, is providedwith an opening the edges of which are accommodated in a groove 3| formed intermediate the ends of the shank 26. At the groove 3| the shank 26 is squared and the opening in the plate 29 is also squared so that the shank 26 is secured. against rotation. Thus is provided a flexible universal connection between the lever I5 and the presser pad or plate 23.

Secured to and extending transversely of the platform It at opposite sides of the pedestal are substantially T-shaped combined guide rails 32 and rack bars 33.

Associated with each combination rail and rack bar is a. standard or pedestal 34 which includes integral angularly related legs 35. The legs 35 have lower ends formed as at 36 to straddle the rails 32 for slidable engagement therewith and to provide teeth or flanges 3'I engageable with the ratchet teeth 33 for securing the standard 34 at the desired adjustment.

At its upper end the standard 34 is formed with an integral socket 38 which slidably receives a shank 39 secured at the desired vertical adjustment through the medium of a set screw 40. The shank 39 is equipped at its top with a head 4I having an upper surface which is flat from the inner to the outer side of the head but is convexed or curved in the direction of the other two sides to permit lateral tilting of a welt plate 42 retained on the head 4! through the medium of screws or the like 43.

The welt plates 42 have feathered edges 43 of proper curvature to correspond to the curvature of a shoe at the shank thereof. (See Figures 1 and 3). I

As will be appreciated the welt plates 42 are adapted to engage the shoe on the last plate 28 at opposite sides of the shank and to fit under the welt of the shoe when the shoe is under pressureduring the repairing operation and to insure perfect contact of the welt with the shoesole to the end that the shoe will be molded back to its original contour incidental to an application of the welt to the shoe.

The manner of using the device in applying a half-sole to the shoe to be repaired may now be briefly set forth as follows: The old shoe, with the worn half-sole thereof removed is placed in an obvious manner on the last plate 20 with the shank portion or remaining arch section of the shoe sole fitting and filling the recess 22 in the last plate 20. The new half-sole is then properly positioned with respect to the shoe to be repaired and with the feathered shank or arch end of the new half-sole overlying the adjacent end of the arch or shank portion of the old shoe. The new half-sole is then cemented to the welt and to the lapped end of the arch or shank section of the old shoe. Next the standards 34 are adjusted inwardly so that the feathered edges 43 of the welt plates 42 are properly engaged with the shoe at opposite sides of the shank section of the shoe and under the welt. Lever i5 is then forced downwardly to force the pad or presser plate 23 into engagement with the arch or shank section of the old shoe and also into engagement with the new half-sole with the welt of the old shoe and the edge portion of the half-sole being clamped between the feathered edges #3 of the welt plates 42 and the edge portions of the presser plate which overlie said feathered edges 43 of the welt plates 42 in a manner to cooperate with the edges of the welt plates for applying pressure to the edge of the half-sole and the welt for adhesively uniting the half-sole to the welt. This pressure of the plate 23 where the feathered edge of the half-sole at the shank. end thereof overlaps the adjacent end edge of the shank or arch portion of the old shoe will also serve to unite these lapped and overlapped edges'toge'ther. Also the pressure of the plate 23 on the shank portion of the old shoe filling the recess 22 will serve for a proper shaping of the shank or metatarsal support of the shoe under repair.

Thus it will be seen that with a device of this character the half-sole is cemented to the shoe and particularly through the medium of this device the desired cementing of the shank end of the half sole to the arch or shank section of the old shoe is readily accomplished, this cementing at this point being more preferable than the present practice of nailing the half-sole at the shank thereof to the original shank or arch portion of the old shoe.

It will be understood of course that the recess or depression 22 in the last plate 29 controls the shape of the insole and consequently the shape of the metatarsal support. Consequently it will be necessary to have enough last plates 23 of various sizes and shapes to permit the repair man to repair any shoe that may come into the shop.

While the structure herein illustrated is designed for cementing half soles on shoes for the left foot, it is to he understood that a properly shaped last plate 28 and welt plates l2 may be substituted when similar work is to be performed for shoes for the right foot.

Having thus described the invention, what I claim as new is:

A device ofthe character described, a pedestal, a last plate supported by the pedestal and provided with a depression, .a lever, supporting means for the lever disposed at one side of the last plate and to which one end of the lever is pivoted, a pressure plate on the lever for movernent therewith into and out of cooperative position relative to the last plate and ocoperable with the depression in the last plate for molding the shoe shank into shape to provide a metatarsal support, a pair of welt plates disposed on each side of the last plate, supporting standards for the Welt plates, means securing the welt plates on the supporting standards for tilting movement in either of two directions. only, a fixed guide rail for each standard, and interengagingmeans on said guide rail and standard whereby the latter is trained to move in a fixed path laterally toward and away from said pedestal.
