Patented Sept. 20, 1938 INSOLE BLANK AND METHOD F MAKING INSOLES THEREFROM Arthur C. Sewall. Auburn, Maine Application January 3, 1938, Serial No. 182,952
21 Claims.
My invention relates to insoles, and methods of and materials for making the same.
This application is a continuation-in-part of applicants co-pending allowed application Serial Number 88,152, med Juneso, 1936.
The invention, which has among its objects the provision of insoles of improved construction,.and methods of and strips for making the same with a minimum waste of material, will be best understood from the following description when read in the light of the accompanying drawings, the scope of the invention being more particularly pointed out in the appended claims. In the drawings: y Figure 1 is a plan view of a fragment of a strip from which the insoles are made, this ligure alsol schematically showing a way in whichv the insoles may be cut from the strip;
Fig. 2 is a section on the line 2-2 of Fig. 1;
Fig. 3 is a plan of the insole;
Fig. 41s a side elevation of the insole according to Fig. 3;
Fig. 5 is a plan view of a fragment oi a modifled form of strip from which a modified form of insole may be made, this figure also showing a way in which the modified insoles may be cut from lthe strip;
Fig. 6 is a section on the line 6-6 of Fig. 5;
Fig. 7 is a plan of the modified form of insole; and Y Fig. 8 is a side elevation'of' the insole according to Fig. 7.
It has been found that womens and other light weight shoes of the McKay, Littleway and similar types may be more easily formed and are more satisfactorywhen in use when the bail or ball and toe portions of the insole are of flexible material. However, if the shank and heel por-4 suitable for the purpose, commonly would be formed of a sheet of material, such as stiff leather,
the outline of lwhich -conforms to the outline of the shank and heel portions of the insole, and would be laid upon the llexible insole and assembled with it in the shoe. Y, Referring particularly to Figs. 1 to 4.of the drawings, applicant has foundthat improved results can be secured,'particularly with a so-called long shankf type of insolel used with FrenchA (c1. 12a-14s) and Louis heels, by making the ball portion I and toe portion 3 ofa sheet of thin, flexible material, such as alpha cellulose fibers felted together to make a bibulous paper which is afterward impregnated with rubber in the form of 5 a hydrocarbon rubber solution or a natural or artificial rubber dispersion such as the natural rubber dispersion known at latex, while the shank portion 5 and heel portion 1 are made of a sheet of stiif, preferably hard, cellulose material such 10 as berb'oard. Conveniently the toe portions of the insole are of the same thickness, or approximately so, and are secured together with rubber cement at a wide, skived joint 9.
i An insole so constructed presents a forward Il portion II of flexible material, which insole is much tougher than one having that portion made of ,upper leather or the like, and presents a rearward portion I3 of stiff, hard material which is much stiffer and harder than sole leather 20 of the same thickness. Further, each portion of the insole may readily be made of the same thickness, and a vplurality of insoles may readily be made of uniform thickness and properties, thusentirely avoiding the necessity of skiving vleather zo.
to a given thickness in the attempt to make insoles of uniform thickness and properties, which leather when skived is usually seriously deficient in tensile strength, stiffness and hardness. l
In th'e preferred way of making the insoles ac-v 30 cording to Figs. 3 and 4 by the improved method a strip is formed having a central or intermediate band I5 of the material of which the rearward -portions I3 of theinsoles are formed. Ce-
mented to the opposite edges of this central band 35 -I by means of skived joints I1 are side bands I9 of the :material of which the forwardportions II of the insoles are formed. From this strip so formed to provide relatively fiexible and stiff zones are cut Athe'insoles, preferably by use of 40 the machine which will die or cut by a stamping operation a plurality of insoles at a time as the strip is fed through the machine. ,The dotted lines 2i in Fig. 1 indicate the portions'of the strip which may be cut to form the insoles. \l3y cutting 4.5 from the strip a row of insoles, so positioned that alternate insoles have their forward portions II cut from opposite side bands I9 of the strip, while all the rearward portions I3 are cut from the central band on outlines in llongitudinal overvai() lapping relation, a great saving in material can be effected. Preferably the insoles are so cut 1 that the' width A between the heel portions of adiacent insoles is less than the width B of those lportions and slightly greater than the width C mi-v,
of the shanks, which permits the shanks to be cut from such portions of width A, and thus cutting the insoles on outlines in lateral overlapping relation eifects a decided saving in material.
If desired the toe portion of the insole may also be or relatively stift material such as ilberboard as shown by the insole according to Figs. 'I and 8. 'I'his insole is exactly like that shown by Figs. 3
' .and 4 'except that only the ball portion I is oi.'
the relativelydlexible material, the toe portion 23. of relatively stii materialbeing joined to the forward end of the ball portion by Ka cemented, wide, skived joint 25.
A form of strip for use in making the insole according to Figs. 7 and 8 is shown by Figs. 5 and 6. 'I'his strip has a central or intermediate band 21 of the relatively stiff material of which the rearward portions I3 of the' insoles are formed. Cemented to opposite edges of this'central band by means of skived joints 29 are bands 3| of the relatively flexible material of whichthe ball portions of the insoles are formed, which 'cemented to the outer edges of the bands 2| by means of like joints 29 are bands 33 of the relatively stiff material of which the toe portions are formed. The insoles may be cut along the dotted lines from the strip so formed as indicated in Fig. 5.
It will be observed that each of the strips above described has between its edges a longitudinally extending zone of the relatively stiff material from which the combined shank and heel' portions are cut, this zone being of widthapproximately the combined `lengths of those portions, and that contiguous with each edge of said zone is a zone of the relatively flexible material of which the ball portion is formed, these last mentioned zones being of width at least approximately the length of the ball portions of the insoles.
