Patented Oct. 13, 1931 IsInoI-tn sIIvIoN, or CHICAGO, ILLINOIS METHODQF MAKING SHOES, INNERSOLES, AND THE Original application filed October 12,

This invention pertains to the method of producing devices such as shoes, and the like, for correcting foot ailments. 1t is known that methods of a similar character have here- 51 tofore been practiced;` however, as lfar as applicant is aware, none of the methods heretofore employed in the manufacture of shoes have embodied the scientific principles rcharacterizing applicants invention as'disclosed V19 in Vthis application. Y

` The present application is a division of my copending applicationiiled Oct. 12, 1927, Serial No. 225,763, which has matured into vPatent No." 1,738,929, granted December 10, 15 1929.

An object v of the present invention is'to provide a method yfor producing shoes,

and

the like, which will prevent and correct abnormal distribution and abnormal direction Y ,20 of forces in the various parts of the human foot.

A further object of the invention is to provide a method for producing devices,particu larly shoes yandy their innersoles, for .the` purcorrecting and checking abnormal strains and stresses and abnormal distribution oi force inthe human foot and for treating feet subi ected to other than normal forces. v

Many other objects and advantages of the method herein shown and described will be lobvious tol those skilled in the art from the disclosure herein given.

To this end my invention consists in the various steps of a novel method for producing shoes, and the like', ycharacterized by the construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

Fig. 11 is a section on the liner 11-11 of Fig. 8 andin addition'thereto showing a split innersole, the position of a wedge asplan view of alast on which ISO sociated therewith, and a concavity formed inthe heel of the' innersole Fig. 12 is a detail view of in Figs. 4' and 5'; and l Fig. -13 is a top plan view of a slightlydifferent form of the innersole employed in practicing the present invention and illustrates a depression in the innersole Jfor the lateral tubercle of the oscalsis as well asthe median tubercle.

In carrying out the present invention, an innersole 25 (see Fig. 2)v` is embossedat 26r before being applied A counterbalance for the ybase of they i'fth metatarsal bone of the foot, the base being a weight bearing point of the foot. The innersoleis then split into upper part 38v and lower part 37 (see Fig. 11) from heel to shank and a leather wedge 27 inserted or a filler at the inner side o the wedge shown to `the last, to form a of the outerfcomponent part Y f roc the heel otherwise provided, its greatest thickness being' on the medial or inner side of the foot. The purpose of this wedge or filler is to counter-balance the lateral tubercle of the oscalsis located in the outer compo-nent part of the foot. Cooperative with the wedge 27 and the boss 26 is tne lill-shaped or semicircular cut-awayv portion 23 (ses Figs. 5 and l2). Cooperating` therewith isthe concave denression 29. One oi the purposes of parts 28Land 29 is to obtain a proper and perfect supportat the heel, particularly on the medial side of the center line. rEhe parts 23 and 29 receive the median tnbercle of the foot. This allows the wedge 27 to extend at least to the center line or` further it desired in order that the proper angle and support at the heel may be obtained in aggravated and special cases. However, in the preferred embodiment, the transverse inclined plane orig;m inates at the center line. rlhe parts 23 and 29 furthermore relieve the median tubercle of undue strain and stresses with attendant tenderness and soreness so common when ordinary shoes are worn and particutarlyY shoes of this general character. The pressure on the ti n or the tubercle is obviously Ireatlv reduced or relieved entirely and the weight is carried over a much lar r surta ce above and immediately surround the tubercle. lt is obvious that other shapes and supports may be substituted for the wedge 27, the wedge beine' merelv the preferred form.

YThe innersole is embossed before beine` applied to the last. The embossed portion 26 is held in place by a boss liller 30 being` formed of vulcanized rubber or other plas tic substance. Its general shape approximates an ellipse. tlat on one side and convex on the other.' It is cemented into the concavitv formed in the under surface of the innersole due to thelembossing and is then covered with canvas or other suitable material 31 and secured in place.

The innersole thus former with mathematical precision is to be incorporated into all sizes and styles ot foot wear. the boss maintained by a vulcanizable or other plastic compound.

A new method of malrinn' shoes is thus provided in which the innersole forms a @cometrical connterbalance tor the weicht bearinn; points of the outer coinnonent `,art et the toot. The embossed portion 2G and wedge 27 form the weight bearin points for the inner component part ot the foot. ness and wedge 2'? occin oj in the innersole proper, leaY-.fing` the interior side of the innersole a plain fiat surface covered with canvas or other suitable material 3l interfering; in no way with the clizmnelingl of the innersole, and not depending in any way upon the cork-gum filler 32 used in `shoe construction to support or maintain the boss 30 or the wedge 27. The

outer sole is shown at 33, the heel of the shoe at 3l and the upper at 40.

The present invention may be carried out on a last 35 with a depression as at 36 (Fig. 3) to receive the inner-sole with the embossed portion 26, the greatest elevation ot' which is located at a point on the center line of the foot opposite the shafts ot the second and third inetatarsal bones, respectively, at the junction of their medial and distal thirds. itt this point is formed one angle of an isosceles triangle, the base and head of the litth metatarsal bone being the other two points, the base of the triangle extending from the point of the juncture mentioned above to the head of the fifth metatarsal. rl`his formation of the depression 3G is accomplished by tooling' out the last to accommodate the embossed portion 26 on the inner-sole. V

The last is further formed with an elevation or boss 39 located approximately centrally of the heel portion. This elevation or boss-like formation fits into the concavit of the depression 29 in the heel seat of the innersole.

The heel of the last is further shaped to receive the elevation on the innersole caused by the wedge by cutting down the wood of l the last shown at al, forming two inclined l lanes all and L12, the plane 41 with its lower pointlocated at the medial or inner border and its highest point terminating` at the center line (see Fig. 8), inclined plane Ll2 with its lowest point located at the posterior border 43 of the heel and terminatiimat the junction of the heel le and shank 45 with the exception of an and the longitudinal f additional elevation 39 at a. point located1 beneath the median tnberele of the oscalsis to [it into the concavity or depression 29 on the heel seat of the inner sole previously set forth.

it will be obvious that, if desired, a thick innersole may be employed, and instead of inserting a wedge in the innersole, the outer side thereof may be out away.

ln Fic.V 6 is shown a depression 50 tubercle ot the oscalsis is applied to an ordinary shoe innersole.

lin Fig. .7 is shown a structure wherein a depression i6 is further lateral tubercle of the oscalsis. This form is preferable in many instances, inasmuch as the depression for the lateral vtubercle is equivalent in certain respects to a. slightly higher wedge.

The last for makingthis form is further the lateral tubercle.
