SHOE UPPER ROUGHENING TEMPLET Filed Jan. 16, 1967 FIG.1 36

IINVENQTOR. Norbert Winig ATTORNEY United States Patent 3,405,416 SHOE UPPER ROUGHENING TEMPLET Norbert Winig, Gloversville, N.Y., assignor to Winlg Slipper Corporation, Gloversville, N.Y., a corporation of New York Filed Jan. 16, 1967, Ser. No. 609,513 4 Claims. (Cl. 12103) ABSTRACT OF THE DISCLOSURE A rigid templet for association with a lasted shoe to precisely define on the turned over portion of the upper, a marginal portion which is to be roughened or abraded.

Background 0 the invention Slippers and the like with their uppers lasted, have turned over marginal edge portions overlying the insole carried by the last. In preparation for the application of the outsole by a cementing operation; the turned over upper portions must be roughened or abraded.

Such roughening operation is conventionally performed by skilled operators who merely present the lasted upper to the rotating abrading brush and by skillful manipulation restrict the roughening to the selected portion of the turned over upper portion. However, such conventional procedure makes for a relatively high cost operation and a substantial number of rejects unless the operator reduces his rate of output, which further increases costs for the operation.

It has been proposed to utilize an automatic mechanism for such abrading operations. However, such a mechanism is extremely complex in structure, entails a high capital investment and results in a high production cost.

It has also been proposed to use flexible, elastic templets for the abrading operation. This approach requires special equipment for mounting the templet and stretch in the templet requires use of the same by a skilled operation with incident high operational costs.

Accordingly, an object of this invention is to provide an improved templet for use in masking the turned over portions of slipper uppers while on a last, to sharply define the surface area which is to be roughened or abraded; such templet being of simple, economic construction and allowing the use thereof by operators of relatively low skills, yet insuring optimum roughening operations.

Another object of this invention is to provide an improved templet of the character described, which is formed of thin sheet metal and permits fabrication thereof to suit the contours of the lasted upper; the same being relatively light in weight and lending itself to easy manipulation by the operator when in use.

Other objects will in part be obvious and in part hereinafter pointed out.

Brief description of the drawing FIG. 1 is a side elevational view showing a templet embodying the invention, in association with a lasted slipper upper;

FIG. 2 is a top plan view thereof;

FIG. 3 is a bottom plan view thereof;

FIG. 4 is a sectional view taken on the line 4-4 of FIG. 2; and

FIG. 5 is a partial side elevational View similar to that of FIG. 1, showing the opposite side of the assembly.

Description of the preferred embodiment As shown in the drawing, designates a template embodying the invention, which is mounted on a lasted slipper upper U on a last L; the upper U having turned 3,405,416 Patented Oct. 15, 1968 over and wiped down peripheral marginal portions M which overlie the usual insole I on the bottom of last L.

It is understood that a predetermined peripheral portion of upper marginal portion M is to be subjected to a roughening or abrading operation as by a rotating wire brush or the like. Such abraded upper portion must be sharply defined since adhesive is to be applied to the same, to secure the usual outsole thereto, in a manner known in the art.

Template 10 comprises a thin sheet metal member 11 which may have a thickness of the order of about Member 11 is formed with a central opening 12 providing said member with an inner peripheral edge 13 and an outer peripheral edge 14. Edge 13 of member 11 has a contour related to the contour of upper marginal portion M so that with last L and upper U thereon, located on member 11; determined surface portions of upper portion M are exposed on the underside of member 11. As indicated in FIG. 1, member 11 may be formed to accurately conform to the longitudinal, as well as transverse contours of lasted upper U.

The upper surface of member 11 is rabbeted outwardly from inner edge 13 thereof, providing a seat portion 15 of reduced thickness and a peripheral shoulder 16. The last L with its upper U is located on member 11 with its marginal portion M seated on seat portion 15.

To further define the exposed surface portions of upper portion M so as to delimit the area thereof to be roughened or abraded, there is provided a pair of very thin,

metal shim members

18, 19 which are adj-ustably mounted on the underside of templet member 11 to define the area to be abraded as at 17.

Shim

members

18, 19 have a thickness which is a small fraction of that of member 11 and have inner and outer edge contours similar to that of member 11. The

members

18, 19 have

inner edges

20, 21 which are adapted to project beyond the inner edge 13 of member 11.

Shim

members

18, 19 are formed with transversely disposed, longitudinally spaced

slots

22, 23 respectively, and are secured to the underside of member 11 by

screws

24, 25 passing through

slots

22, 23 and threaded into threaded openings 26 in member 11. The

opposite ends

26, 27 of shim member 18 overlie the

opposite ends

28, 29 of shim member 19.

The last L and the upper U thereon is held in place on templet 10 by a pair of upstanding abutment members 30 on the foreportion of the templet; said members being formed of synthetic plastic and positioned on the templet so that the inner surfaces 31 thereof abut the adjacent portions of upper U. Similarly, a second pair of abutment members 32 upstanding from templet member 11 on rear portions thereof have their inner surfaces 33 abutting adjacent portions of upper U, and finally, a single upstanding abutment member 34 on the rear of member 11 has its inner surface 35 abutting the adjacent rear portion of upper U. The

abutment members

30, 32 and 34 are secured to member 11 by screws or the like.

Means is provided for tightly holding the upper U on its last L in association with templet 10. To this end, a hold down bar 36 is adapted to straddle the narrow top surface 37 of last L and to be releasably locked to templet member 11. To this end, a relatively long strap member 38 of thin metal and a relatively short strap member 39, also of thin metal; which are slotted at their upper ends, are respectively secured to the opposite ends of bar 36 by

screws

40, 41 passing through the slotted portions thereof and received in threaded openings in the opposite ends of bar 36.

A fixed strap member 42 is secured at its lower end to an upper surface portion of member 11, as by solder, welding or the like; the upper end of member 42 being hingedly connected to the lower end of the short strap member 39, as at 43. A latch member 44 of thin springy metal is hingedly connected at its upper end to the lower end of the long strap member 38, as at 45. Latch member 44 terminates at its lower end in a reversely bent U shaped clip portion 46 which is adapted to snap into engagement with an outer edge portion 47 of member 11.

Thus, the last L carrying upper U with turned over upper portions M on the underside thereof, is tightly held in place on templet 10. The

thin shims

18, 19 can be adjusted as to their positions on the underside of templet member 11 to precisely frame the exposed upper portion M which is to be roughened or abraded. Accordingly, the resultant assembly may be presented to the usual rotary abrading brushes to roughen the exposed upper portion M.

It is understood that a series of tcmplets of respectively different slipper or shoe sizes, are provided for association with corresponding lasts and uppers. The slotted

shim members

18, 19 allow for very fine adjustments of the positions thereof on member 11, thereby adjusting the upper area to be roughened, as required.

As various changes could be made in the embodiment of the herein disclosed invention, without departing from the spirit of the invention, it is understood that all matter herein shown or described shall be deemed illustrative and not limiting except as set forth in the appended claims.
