UNITED" STATES PATENT OFFICE SHOE SOLEPRESS Michael Muscarella,`Nunda, N. Y.

Application April 1, 1932. Serial No. 602,577

1 Claim.

The invention relates to a press and more particularly to a shoe sole press for cementing soles upon footwear.

The primary object of the invention is the provision of a press of this character, wherein a distendable pad is arranged so that when pressure is applied to footwear on the application of the sole thereto by cement the said pad will firmly hold the sole in place and upon the footwear for the cementing of said sole thereto.

Another object of the invention is the provision of a press of this character, wherein equal pressure throughout the entire sole of a shoe will be had whereby such sole may be cemented to a shoe irrespective of the size and shape thereof or the character of such shoe, that is, for men or women.

A further object of the invention` is the provision of a press of this character, wherein equal pressure is assured under the action of fluid contained within a flexible and yieldable pad so that the latter will conform to the contour or shape of the shoe and especially when under pressure so as to maintain the sole in proper position for the cementing thereof to the shoe.

A still further object of the invention is the provision of a pressV of this character, wherein the pad as arranged therein is prevented from tearing away or otherwise separating from the base of the press when in use and such pad can be filled to the desired quantity with fluid to have the same flex or yield for its conformation to the shoe in the applying of the sole thereto by cementing such sole.

A still further object of the invention is the provision of a press of this character which is extremely simple in construction, thoroughly reliable and efficient in its purpose, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawingz Figure 1 is a side elevation of the press constructed in accordance with the invention showing the shoe in position for the cementing of the sole thereto and such shoe is of a womans type.

Figure 2 is a front elevation of the press.

Figure 3 is a top plan view.

Figure 4 is a bottom plan view.

Figure 5 is an enlarged vertical longitudinal sectional View taken on the line 5-5 of Figure 2 looking in the direction of the arrows.

Figure 6 is a fragmentary sectional view on 60 the line 6-6 of Figure 5 looking in the direction of the arrows.

Figure 7 is an enlarged transverse vertical sectional view.

Similar' reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the press comprises a base 10 preferably made from metal although it may be made from any other suitable material and carries a marginal rest flange 11, the latter being preferably separable from the base and is held secured through the medium of a plurality of bolts 12 carrying nuts 13. This flange l1 is formed upon a framing plate 14. Upon the base 10 is a flexible yieldable pad 15, preferably made from rubber and is clamped upon the baseY 10 by the framing plate 14, so that the said pad 15 will form independent pockets or chambers 16 and 17 respectively, into which can be introduced a fluid 18 such as water or other liquid or airor gas. The iluid 18 is introduced through a suitable port or opening having removably fitted therein a closure plug 19.

Bridging the base is a yoke or frame 20 havv ing adjustably fitted therein feed screws 21, these being vertically disposed directly over the pad at the two pockets or chambers 16 therein and engageable with each of these feed screws is a last 22 which is adapted to be introduced into a shoe for the holding of the same in position relative to the pad for the application of a sole 23 to the shoe by cementing of the said sole thereto.

Each feed screw 21 is adapted to accommodate a hand wheel 24 for convenient adjustment thereof.

It will be apparent that when the pad l5 has the chambers 16 and 17 supplied with fluid 18 on the application of the sole 23 to the shoe carried by the last 22 when positioned within the press as shown in Figures 1, 5 and 6 of the drawing the pad will flex or yield with the pressure of the fluid therein in all directions and thus conform the sole 23 to the shape of the shoe and in this manner the said sole can be cemented to the shoe while the pressure of the fluid within the pad will maintain a uniformity of such pressure throughout the area of the sole 110 and thus such sole will be completely cemented throughout its extent to the shoe.

The yielding and flexing of the pad 15 enables it to correspondingly shape itself to the contour of the shoe at the sole thereof and thus' pocket the said sole 23, while the shoe will be clamped in proper position by the last 22 and held fast by the screws 21.

The press by reason of its construction will permit full soles to be cemented to a shoe, that is, from the toe to the heel thereof and in this instance it is of course understood that theheel proper is subsequently mounted upon the shoe.

By reason of the formation of the framing* plate with the walls 25 about the pad 15 there will be no liability of the pad tearing away or otherwise becoming detached from the base of the press, the base being also formed with an inner wall or rib 26 which confronts the clamping extent of the pad 15 upon the base.

What is claimed is:-

thereof, a rib upstanding from the closure vplate and crowding the pad against the upstanding flange of said frame, means securing the closure plate tothe frame, a removable plug fitted in said closure plate, and presser means carried by the frame for directing and pressing a shoe against `the pad to have its sole rest in the seat in the latter.
