9 Claims.

This invention aims to provide functionally and structurally improved articles, primarily intended for use in connection with the manufacture of shoes, and also aims to teach a novel l'5 method of manufacture in connection, with thel production of shoes.

It is an object of the invention to provide a sole of novel construction, and by means of which the methods of manufacturing shoes may be yl greatly improved.

A further object is that of providing an inset or iiller piece in connection with the use of insoles and by means of ,which the resultant product will be greatly improved.

l A still further object is that ofteaching a method of manufacturing shoes, which method will preferably employ soles and ller pieces as afore noted, the practice of such method resulting in the expeditious manufacture of shoes having improved characteristics.

- Moreover, by means of the present invention, there are provided soles and insets which may be economically manufactured in large quantities, and the method as taught by the present invention will not require the services of an especially skilled workman.

With these and other objects in mind, reference is had to the attached sheet of drawings illustrating practical embodiments of the invention, and in which:

Fig." 1 is a perspective View of an inner sole;

Fig. 2 is a transverse sectional view taken along the lines 2--2 and in the direction of the arrows as indicated in Fig; 1;

Fig. 3 is a perspective view of a shoe-upper and showing the same in association with a sole of the type illustrated in Fig. 1, during the lasting operation;

Fig. 4 is a view similar to Fig. 3, but showing the shoe after the same has been subjected to a further step of manufacture;

Fig. 5 is a transverse sectional view of the shoe and sole as illustrated in Fig. 4, with an outsole added;

Fig. 6 isV a sectional and perspective Aview (cl. iz-uz) by leaving uncut or unscored zones Il, and deliberate destruction oi which is, of course, necessary to eiect removal 'of the portion I2.'

In forming the slit or score Il, care is preferably taken so that the edges shall be beveled as- 5' at Il in Fig. 2. It is obvious that this beveling might be followed to any desired extent, and might readily be conducted at the time the sole is stamped or cutout.

In any event, the inner sole l0 and the upper I0l I5 may be `applied in the usual manner to the last I6, and the lasting operation is conducted in any suitable manner, as, for example, by cementing the lasting allowance I1 to the margins I8 of th'e insole. During this operation, andincident to 15 the central portion l2, the insole will oifer suiili cient-resistance to buckling so -that no dilculties may be apprehended. Thereafter, by simply cutting through the zones I3, the central portion may be removed. 20

The operator may now apply to the insole the iiller piece I9, which piece should be of a thickness such that it will extend from the plane of the inner face of the sole l 0 to the plane of the outer face of. the lasting allowance. While, for the 25 purpose of illustration, the filler piece has been shown as having a somewhat reduced area', it will of course, be understood that preferably the area thereof should be substantially equal to the area between the inner edges of the lasting al- 30 lowance so that substantially continuous surfaces are provided. v

Of course, before the application of the illler piece I9, but after the removal of the central portion l2, the operator may modify the, edges of 35 the central opening as may seem most desirable. Such modification may take the form of beveling to a greater extent than has been done prior 'tol the application of the inner sole to the upper. Alsoas shown, in Fig. 7, the filler piece need not i0 necessarily have those edges which contact the edges of the central sole beveled, but instead a shoulder 2li may be provided at this point, the

n depth of the shoulder being such that the inner cementing be resorted to to assure a permanent union between these parts. In many respects it is preferable that slitting, as indicated at il, be resorted to, but it is obvious that, regardless of whether a composition or other sole is being utilized, a line of weakening might be furnished, as, for example, by a crushing action, which would substantially remove said portion but nevertheless leave in existence a thin layer of material, precluding accidental detachment of such portion. Under the latter circumstances the unsevered areas i3 might be utilized or entirely dispensed with, in that the operator could very easily complete the removal of the central portion. In certain instances, and especially where scoring is utilized, these unsevered areas mightagain be dispensed with.

From the foregoing it is obvious that a sole is provided and a method taught which will permit of adequate support being furnished during the lasting operation and by means of which, after such operation has been completed, the rigidifying portion may be removed with facility and replaced by a filler piece or inset which will assure the incorporation of maximum flexibility and comfort in the resulting shoe. The outer faces of the lasting allowance and inset might be skived, so that the outer sole might readily be cemented thereto, it being, however, immaterial-in so far as the present invention is concerned-whether cementing, stitching, or other forms of attachment are employed.

It will be noted, particularly in Figs. 5 and 7, that by virtue of the thickened insert in the inner sole the latter hasa centrally elevated portion or landwhich projects outwardly from the bottom face "of the lasted upper. The boundary of this landed portion approximately coincides with the inner boundary of the inner sole lasting allowance, and in the complete lasted upper assembly there is a` substantially even surface extending from side to side of the shoe which is adapted tomate firmly and snugly with an outer sole, which latter may be readily manufactured in a flat condition with a minimum number of preforming steps.

From the foregoing,l it will be obvious that, among others, the several objects of the invention as specifically afore noted, are achieved. It will be appreciated that numerous changes in construction might be resorted to, and that the steps and the method might be varied in many respects without departing from the spirit of the invention as dened by the claims.

Having thus described the invention, what is claimed as new and desir`ed to be protected by Letters Patent is: Y
