PATENT-"OFFICE 'f K .71,926,765 Y A llfET-EOD QFMAKINGINNERSOLES Y "l Frederick VW. Eager, Arlington, Mass.. assigner toeckwith Manufacturing Company', Boston, Masswa corporation of 'Massachusetts ApplicationuApril 8,1930. SerialNoffliZZZ 'lfClairn' (Cl. 12-146)' Figure 8 is a fragmentary transverse section This invention relates to innersoles for those types of shoes, wherein-the upper` materials are lasted over flat against` the outer faceKV ofthe innersole'such as McKay, Littleway, and cement 5 process shoes. When such an innersoleis a at piece of substantially uniforinthickness throughout, as heretofore constructedk andthe edges of the upper are lasted thereover, these edgeY por- 4 tions form a marginal rib about thev edge of the 10 innersole which requires va filler to befapplied to the central portion of the innersole in order that a substantially fiat surface laterally of the shoe may be presented `to receive the outersole. Commonly' the upper margins are not lastedin ceive the edges of the upper material, but to' facilitate making such a construction and to per`- mit the use of relatively thin cheap innersole stock, I preferably apply tothe usual flat innersole face a composition layer which may form a combined filler and heel seat brace and then remove suiiicient of the marginal portionof this layer material to form a pocket or depression to receive the edges of the upper. Thus a relatively thin innersole stock may be employed and yet provide the necessary ller thickness.
Fora more complete understanding of thisinvention, reference may be had to the accompanying drawing in which Figure l is a perspective of an innersole blank as heretofore made. Y l
Figure 2 is a fragmentary diagrammatic seca tion showing the method of applying the filler material to the innersole stock'either before o1"V after it is cut into innersole blanks.
.Figure 3 shows in perspective a coated innersole blank, a part of the margin of thellerlayer being cut away.
Figures 4 and 5 are cross sections through the forepart portions of fully prepared innersolesl showing` different methods of forming to receive the lasted edges of the upper. Figure 6 is a crosssection through the fore-` part of the lasted shoe,y a portion of the upper material having been trimmed.
Figure '7 is a fragmentary perspective of the heel portion of aY prepared innersole illustrating `'about the heel seat of the innersolesso that a i ,l through the heel portion of a .shoe showing the f innersole of Figure 7 and providedwith a Wood heel. i v
Referring Y to the drawing, a suitable sheet material'of relatively thin stock, such as has heretofore been employed Yfor the manufacture of innersoles `for the flat innersole type shoes, such A i v as McKay, Littleway process and cement process shoes are provided Withacoating layer 3 of ina-1 terial suitable for useas a innersole filler. This material may well be rformed from initially plastic material, such as the mass shown at 4, which may-be rolled onto one face of the sheet 1 to form a self -bonding layer of the desired thickness. Material suitable for this purpose should be capable of being rendered initially plastic and should adhere to the innersole and flex therewith during kuse without cracking, and without flowing too.
readily after having been once applied and hard-- ened. p
While many compositionsvmight bev used, one composition which is suitable for the purpose may be made up as follows: 21/2 pounds of rubber inthe form of smoked sheet; 1 pound of asbestos fiber; ll/pounds of resin; 1A pound of ground cork; 1 ounce Zinc oxide and 1 ounce of sulphur may be compounded in a mixer or mill. When Ythe mass is reduced tothe desired consistency Yit maybe supplied to the nipbetween a pair of rolls 10 and 11 as shown in Figure 2,r these rolls being spaced so as to leave the desired uniform thickness of material on one face of thefounda-k tion layer of sheet material. This coating material should be applied while warm and then be permitted to harden, and may be applied either]- before or after the sheet material is cut into the i shape of innersole blanks, as shown in Figure l,
but preferably is applied before the blanks .are 1y cut, since it is then easier to insure a uniform.v Ycoating of the material.
After the material has solidied a portion about the margin of the innersole is cut to form "a seat to receive the margin of the upper materiale during i-the lasting operation.
Y VAs shown in Figuresl 3 and 4 this seat may be formedby removing the4 entire marginal Yportion -of vthe Y coating layer as by channeling or by any other suitable method, the seat being shown at 15.l In
place of removingfthe whole thickness of theY lcoating layer it maybe skived as shown at 16 in Figure 5. As shown inFigure 3, the seat is not formed to extend about theV heel end portion of the innersole, the coating at this'portionof the innersole being left its full'thickness and formfsb ing a heel seat braceras lat 1'7 integrally connected with the filler portion 18 between the margins cut to receive the marginal edges of the upper'.
As shown in Figure 6 these upper materials as 20, including the outer upper materials 2i and the lining 22, may be lasted over the margin ofthe innersole and secured thereto by any suitable means, this means depending on the type of shoe which is to be made. The margins of the upper materials which initially may extend inwardly of the seats 15 are then trimniedoil,V as shown at Athe left hand portion of Figure 6,
so that the lower face of the upper materials at their margins is substantially vvin'V lateral alinetic composition to one face of innersole stock to ment with the lower face of the fillerjl. p
Instead or" terminating .the marginal seat of the innerscle forwardly ofthe heel seat, it may be extended entirely around the edge including the heel end'oi the innersole, as shown at 25 in Figure 7, this seat beingv occupied not only by the upper materials, but by the attaching flange 26 of the counter stifener 27, as shown in Figure 8. The central portion of uniform lthat the margin 30 of the wood heel may closely engage the upper.
From the foregoing description ofr certain ernbodiments ofV this invention, it should be evident 'to those skilled in 'the art that various changes and modifications might be made without departing from the spirit or scope of this invention as defined by the appended claim.
VI claim: l
The method which comprises applying a plasform a layer of a thickness suitable to form an nnersole iiller, permitting the layer to harden, and then removing sufficient oi said layer about the margin of an innersole blank cut from such stock to form a seat to receive the lasted margin of a shoe upper.
