' INVENTOR Z W Z. Z4auLMo BY Z y WW ATTORNEYS 3,534,420 PAD BOX Harold E. Marasco, Beverly, Mass, assignor to Marasco Shoe Machinery Company, Lynn, Mass, a corporation of Delaware Filed Aug. 22, 1969, Ser. No. 852,419 Int. Cl. A43d 63/00, 89/00 US. CI. 12-38 Claims ABSTRACT OF THE DISCLOSURE A new and improved pad box having provision for interchangeably presenting mold members of different shape for conforming a heel breast flap to the breast surface of a heel already attached to the bottom of a lasted shoe.

This invention comprises a pad box for use in sole presses designed to lay on the bottom of a lasted shoe a sole having an already attached heel, and at the same time to conform a covering flap to the breast surface of the heel. This surface presents compound curvature, longitudinal taper and, of course, varies in length or height in shoes in process of manufacture.

The present invention solves the problem of conforming the breat flap, under usual manufacturing procedure, smoothly and completely for adhesive attachment to the heel. It consists in providing means for framing within definite limits the area of the heel breast to be covered, and providing a mold member or breast pad operative exclusively on the framed area of the breast. This novel construction has been found to expedite and improve the flap conforming step of the process and so contribute an important shoemaking advance in the art.

The invention includes a novel construction for interchangeably mounting a breast mold or pad in position to operate upon the framed area of the breast surface. As herein shown, this comprises a holder externally secured to the pad box and provided with ways or other means for receiving any one of an assortment of mold members.

This and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which FIG. 1 is a view of the rear end of the box in longitudinal section showing a shoe in operative position.

FIGS. 2 and 3 are views in perspective of the rear end of the pad box,

FIG. 4 is a plan view of the flap conforming pad, and

FIG. 5 is a sectional view on the lines 5-5 of FIG. 1.

My improved pad box as herein shown is designed for use with a sole press for heel-attached shoe bottom such as described in my prior Pat. 2,962,736 Dec. 6, 1960, to which reference may be had for details of construction.

The forepart of the box comprises a bottom and upright side walls 11. A two-ply flexible pad is secured to the top of the side walls by clamping plates or straps 13 and the pad is extended downwardly at its rear or heel end 12 as shown in FIG. 1. At its lower edge it is clamped against the bottom 10 of the box by a so-called constricter plate 14. This has a rectangular window 15 which in the assembled box registers with the heel flap desired to be conformed to the breast surface of the heel. The upright side edges of the window are spaced to receive the full width of the heel breast between them.

3,534,42 Patented Oct. 20, 1970 An open-top holder 16 is secured to the constricter plate 14 by bolts 17 and provides a vertical slideway for a rectangular flap-conforming mold pad 18. This may be molded of stiff resilient material such as natural or synthetic rubber. It is substantially rectangular in shape and beveled about its edges so that it may be conveniently inserted in or removed from the frame 16. It may have a surface contour compatible with the work in hand.

It will be understood that the window 15 opens from the pad box into free space and that the mold pad 18 lies against the outer surface of the plate 14 where it may be conveniently inspected and interchanged.

It has been found that the combination of the window 15 with the conforming pad 18 is particularly effective in laying the breast flap smoothly against the heel and causing it to adhere permanently and completely to the edges of the heel breast. It will be apparent that the pad 18 may take any contour best adapted for dealing with heels of various heights and styles and that a suitably shaped pad may thus be drawn from an available supply.

The successful and superior operation of my improved pad box is due in a large extent to the framing of a limited area of the heel breast and the concentrated action of the conforming mold member in this framed area.

Having thus disclosed my invention what I claim as new and desire to secure by Letters Patent is:

1. A pad box comprising a forepart section closed at its heel end by a transverse plate provided with a window opening into free space and arranged to frame the breast face to a sole-attached heel placed within the pad box, in combination with an open holder secured to a part of the box and a flap-conforming mold member removably retained by the holder in registration with said Window and in contact with the outer surface of the plate.

2. A pad box as described in claim 1, further characterized in that the holder is secured to the outside of the pad box and presents guideways for the reception of selected flap-conforming mold members.

3. A pad box as described in claim 1, further characterized in that the window of the transverse plate and has parallel upright edges which define the area of heel flap contact by the flap-conforming mold member.

4. A pad box as described in claim 1, further characterized in that the heel portion of the box is closed by a transverse constrictor plate secured at its ends to the upright side Walls of the box, having a centrally located window and an external holder for registering and supporting a flap-conforming mold member in fixed position with respect to the window.

5. A pad box as described in claim 1 further characterized in that the said window is located to expose the area of the breast surface to which the flap is to be conformed, and the flap conforming mold member is arranged to engage the breast flap only within the framed area.
