Patented Dec. 17, 1935 UNITED STATES PATENT OFFICE Joe Lieberman, South Bend, Ind.

Application April 15, 1933, Serial No. 666,330

2 Claims.

The invention relates to sole pressing members for shoe presses, and particularly to a pressing member employed in a shoe press for cementing soles on shoes. These shoe presses comprise a base which mounts a frame by which the sole pressing member is carried. The shoe, to which the sole has been applied by cement, is disposed on the sole pressing member, and a sole last is inserted in the shoe to bear against the sole thereof. Pressure is then applied to the last by suitable means, whereby the last and shoe sole are pressed against the sole pressing member while the cement applied to the sole is setting. In order for the device to achieve the best results, it will be obvious that the sole pressing member should be shaped to conform to the contour of the shank and sole of the shoe to provide the proper support for the shoe while the sole is being cemented.

This support should obviously be a face contacting support for the entire surface of the shank and sole of the shoe.

It will be seen that, to be practical, some provision must be made in the sole pressing member to accommodate the various contours of the soles and shanks of shoes of different sizes and makes and having different heel heights, since otherwise an almost infinite number of sole pressing members would be required for use in connection with 7 each shoe press. To provide an adjustable sole pressing member operable to accommodate any shoe is therefore the principal object of this invention.

A further object is to provide a device of this character which automatically shifts to accommodate its shape to the contour of the sole and shank of a shoe pressed thereagainst.

#A further object is to provide a device of this character comprising a frame and a pair of cooperating plates shiftably carried by the frame.

A further object is to provide a device of this character comprising a flexible pad which is supported by a pair of shiftable cooperating plates.

With the above and other objects in view, the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawing, which illustrates the preferred embodiment of the invention, the numeral I0 designates the shoe press which comprises a base I l on which is mounted my improved sole pressing member [2. The sole pressing member I2 is preferably provided with laterally projecting ears l3 which are apertured to receive the lower ends of vertical rods 14 which support the ends of a horizontal bridge member l5, spaced above support or sole pressing member 12. A pair 25 of spaced bosses l6 are provided in bridge member I5, which bosses are provided with threaded vertical apertures in which bolts ll each provided with an operating handwheel 18 are mounted. The bolts I! are each positioned to bear upon a sole last I9 which is fitted in a shoe 2B which is mounted upon the sole pressing member l2.

The sole last l9 may be of any desired construction, but I prefer to employ a last of the construction illustrated in my Patent No. 1,928,258, issued September 26, 1933. This construction of last, as illustrated in Figure 6 herein, comprises a base plate 2! which is hinged at its rear end at 22 to a shank plate 23. A handle member 24 projects upwardly from plate 2 l, and the bolt ll bears on the upper face thereof to apply pressure to the last. A recess 25 is formed in one side face of handle 24, which recess is of the shape of a sector of a disc. A flange 26 of sector shape fits into recess 25 and is carried by plate 23. A plurality of apertures 21 are formed in the flange 26 and are selectively brought into registration with an aperture formed in handle 24, through which registering apertures a pin 28 may extend to hold the shank plate 23 in desired angular relation to base or sole plate 2| to conform to the inner contour of the sole and shank of a shoe.

The sole pressing member l2 against which the last I!) presses a shoe sole while the cement applied thereto is setting is comprised of a frame 39, preferably cast and shaped to receive both right and left shoes. Each section of the frame 30 is defined by a vertical curved'plate 3 I, the rear ends of which are connected by a vertical plate 32 of lesser height than plate 3|. A transverse plate 33 is disposed centrally of each section of the frame at the lower side thereof for purposes to be hereinafter set forth. An inwardly downwardly inclined flange 34 projects from the front of each section at a height substantially equal to the height of plate 32, and is provided with a longitudinally elongated slot 35 extending therethrough. A pair of recesses 36 are formed in opposed relation in the plate 3| in rearwardly spaced relation to bar 33, and extend from the upper edge of plate 3! to a point substantially horizontally aligned with the upper edge of plate 32.

A sole plate 31 of a shape conforming to the forward portion of each section of frame 30 and of a size to move freely therein is disposed in each section of frame 39, the upper face of said plate 3'? preferably being slightly concaved in accordance with the normal convexity of the sole of a shoe. A perpendicular pin 38 depends from the bottom of plate 3'? adjacent the forward end thereof to fit into the slot 35 of flange 34. The plate 31 terminates in rearwardly spaced relation to bar 33 and is provided with a depending transversely extending convex bead 39 at its rear end. A shank plate 49 is disposed in the rear portion of each section of the frame 30 and conforms With the shape of said frame and is shiftable relative to the frame. A pair of opposed laterally extending pins 4| project from the sides of plate es and are mounted in recesses 36 to pivotally support said plate in said frame. The plate 40 is of a length to engage plate 32 at its rear end when substantially horizontally positioned and to underlie the rear end of plate 31 at its forward end. The forward end of plate 40 is provided with a transversely extending concave lip 42 which normally receives the convex bead 39 of plate 37, said lip being downwardly off-set from plate 40, whereby, when said plates 3'! and 40 are disposed in parallel relation as illustrated in Figure 4, the upper faces thereof will be substantially aligned.

A flexible pad 43 conforming to the shape of each section of frame 30 is mounted in each of the frame sections and is supported by plates 31 and 43, said pad preferably being formed of soft rubber. r

In the use of the device, the shoe is disposed upon pad 43, whereby said pad supports the sole and shank thereof. The last 19 inserted in the shoe and adjusted to conform in shape to the inner contour of the sole and shank of the shoe is then pressed downwardly by bolt I! to deform pad 43 and shift plates 31 and 40 to relatively angular position, as'illustrated in Figure 3. The pressure 7 applied to pad 43 and plates 31 and 40 shifts said plates and flexes said pad whereby the pad assumes and is firmly supported by the plates in a position wherein it conforms to the contour of the lower face of the shank and sole of the shoe. While the pressure is so maintained the sole and shank of the shoe are firmly pressed at the upper and lower faces thereof and throughout the full extent thereof to permit the cement applied to V the sole, as in applying a half sole to the shoe, to firmly set and adhesively securesaid half sole to the shoe. It will be observed that this construction of sole pressing member is operative to adjust its position to accommodate the contour of the shank and sole of any shoe.

The invention having been set forth, what is claimed as new and useful is:

j 1. In a sole pressing member for a shoe press, a frame including a vertical plate configured to receive the front portion of a shoe and a flange projecting inwardly of said frame at the front thereof, .said plate being provided with a pair of opposite recesses adjacent the rear thereof, a pair of cooperating plates mounted in said frame, one of said plates being supported by said flange, ears projecting intermediate the length of the other plate and disposed in said recesses to pivot said plate, said last named plate engaging said first plate, and a flexible pad mounted on said plates, said pad flexing to conform to the contour of the sole and shank of a shoe pressed thereagainst and shifting'said plates to relatively angular position to accommodate said flexing.

2. In a sole pressing member for a shoe press, a frame, a pair of plates shiftably carried by said frame, a convex bead carried by the bottom face of one plate at one end thereof, and an offset 45 concave lip carried by the other plate and underlying said bead, and a flexible pad mounted on said plates, said pad flexing to conform to the contour of the shank and sole of a shoe pressed thereagainst and shifting said plates to relatively angular position to accommodate said flexing.
