llllllllllll- Patented Feb. 15, 1938 UNITED STATES MACHINE FOR TREATING HEEL SEATS F SHOES Application September 12, 1936, Serial No. 100,437 3 Claims. (01. 12-315) This invention relates to machines used in the,

manufacture of foot wear, and more particularly to heel seat cutting-on machines.

General objects of the invention are to provide a heel seat cutting-on machine and a heel measuring indicator of improved construction which are adapted to enablean operator rapidly and efficiently to position a soled shoe with respect to a heel seat cutting device in accordance with the measurement of-the heel which is to be applied to such seat;

Further objects are to provide such cutting-on and such indicating devices which are-easy to handle and do not require undue care or skill on the part of the operator, are simple and rugged in construction, unlikely to get out of order and which accurately control the dimension of the heel seat cut in accordance with the measurement of the applied heel.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the invention will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. l is a plan view showing a heel size indicator and an associated cutting-on machine embodying principles of this invention, certain parts being broken away better to show the underlying structure;

Fig. 2 is a' vertical sectional View taken along line 22 of Fig. 1;

Fig. 3 is a transverse vertical sectional view taken along line 3-3 of Fig. 2;

Fig. 4 is a transverse vertical sectional View taken along line 4-4 of Fig. 1; and

Fig. 5 is a fragmentary perspective view showing a heel seat after the cutting-on operation.

In cutting-on heel seats for the reception of heels havingaconcaveupper surface, such as Louis wood heels or related types, it is customary to remove a horse-shoe shaped marginal strip from the outsole at the heel of the shoe leaving a construction like that shown in Fig. 5, where the outsole A has such a marginal strip removed so as to leave a central tongue B at the heel seat. This tongue at its forward end meets shoulders C adapted to be abutted by the forward edge of the heel. This leaves exposed a marginal portion of the upper materials at D which latter in accordance with well-known procedure is adapted to be 7 roughed and cemented, together, if desired, with the tongue B, in order that a heel may be adhesively affixed thereto. Itis obviously important that the shoulders C be precisely located in accordance with the length of the particular heel to be applied, and since even heels of a given size vary somewhat in length, it is desirable that each cutting-on operation be controlled by the particular heel which is to be used on that shoe.

The present invention provides a heel measuring indicator adapted to position an indicating marker in accordance with the gaged measurements of a particular heel. preferably there is associated with this indicating device a cutting-on machine, which has a control pointer conveniently arranged to register with the indicator marker, and which controls the position of a shoe engaging rest to determine position of the shoe with respect to the cutting device in order to control the position of the shoulders C.

Referring more particularly to the drawing, and first to the heel size measuring and indicating device, there is shown a bed plate [0 carrying a heel gage comprising a fixed abutment II and an opposed movable member i2 adapted to have a heel positioned therebetween as shown in dotted outlines in Figs. 1 and 2. The member I 2 has a downward projection guided in a slot I3 in the bed plate and carrying a pin to which a tension spring [4 is attached in order to give the member I2 a normal bias toward the-fixed abutment H. The member- I2 carries a rack E5, the outer end of which is guided between a roller l6 and a pinion IT. vertical shaft 18 and has fixed thereto an indicator disc l9 having a visual marker 26 thereon, which may comprise a line or arrow point extending radially to the edge of the disc. This disc is preferably of pronounced radial extent so that the marker at its edge will traverse a considerable distance upon relatively slight rotational disc movement.

When the gage member 12 abuts the end of a heel held against gage abutment l I, the indicator disc and its marker 20 will assume a position corresponding to the length of the measured heel.

The marker 20 need not be mounted on a disc, if desired, but may comprise a single arm swinging from the pinion I1. Also, if desired, the heel measurement may be indicated by putting a calibrated size scale on the disc in position to move past a fixed marker (such scale and marker are This pinion'is freely rotatable on a not shown), or such a calibrated scale may be positioned adjacent a single pointer such as that at on the indicator disc. Preferably, however, a single marker such as 20 is swung from the pinion I! in position to have alined with it a control' for the cutting-on device about to be described.

This cutting-on device comprises a base 2| having a recess 22 open at the forward side of the machine for reception of the heel end of a shoe, as shown in Fig. 3. A sole supporting plate 23 caps this recess 22 and is adapted tobe inserted between the heel portion of a lasted upper and the heel portion of an outsole A which may preferably be attached to such upper throughout its forepart and shank but not at its heel. A plunger carrying a die 24 is mount-ed for reciprocation above the plate 23, such die having a U-shaped cutting blade joined at its forward ends to transverse cutting blades adapted to out the tongue B and shoulders C in a single stamping or dinking operation.

A rest' 25 is provided which is adapted to have the rear end of the shoe seated thereagainst in order to position the shoe with respect to the cutter die 24. This rest has a rearwardly extending tail 26 which is slidlngly accommodated in a suitable aperture provided between the base 2| and the plate 23 and is supported on a ledge 21 extending rearwardly from the base 2!. A tension spring 28 extends from a fixed pin below such ledge to the rest 25 and gives the latter a normal rearward bias.

At its rear end the tail 26 is smoothly beveled for sliding contact with the inclined surface of a wedge 29 having a guide groove 39 slidable over a pin 3| fixed to the ledge 27. This wedge carries a rack 32 guided between a guide roller 33 and a gear 34 with which the rack meshes. This gear is preferably concentric with the indicator pinion H and to this end may conveniently be freely rotatably mounted on the same shaft 18, which latter may be fixedly carried by an arm 35 extending from the base 2|.

A handle 35 is fixed to the gear 34 and carries a pointer 31 adapted to be alined with the indicator marker 20.

The inclined face of the wedge 29 is so designed that the considerable rectilinear movement imparted to such wedge upon axial movement of the gear 24 is transmitted to the tail 26 in a considerably reduced proportion so that considerable axial movement of the gear effects relatively slight adjusting movement of the rest 25. The parts are also proportioned so that when the indicator marker 20 is positioned in accordance with the length of a heel measured by the gage at H and I 2, and the control pointer 37 is in alinement with such marker, then the heel rest 25 is properly positioned with reference to the cutting die 24 to locate the heel seat shoulders C at the proper points along the length of the shoe to assure an accurate fit when the heel is thereafter cemented in place on the heel seat. By virtue of the motion reducing mechanism between the pointer 2! and the heel seat 25, it will be seen that sufiiciently accurate results will be obtained so long as the pointer is put by the operator into reasonably accurate alinement with the marker 20. Thus the operator may quite rapidly and without undue care position the rest 25 by suitable manipulation of the handle 36.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
