This invention relates to an improved method of manufacture of boots and shoes whereby the toe portions and ball portions thereof can be made without metal tacks, nails or wire staples so that there is no danger of metal working into the interior of the shoe so as to be liable to injure the foot. By means of the improved method of manufacture the use of separate bottom filling materials is unnecessary thus avoiding the necessity of using additional materials as usually employed for this purpose whilst at the same time obtaining increased flexibility and comfort.
According to the present invention an insole for use in the manufacture of boots and shoes is marginally reduced in thickness on its lower surface, to form the equivalent to bottom filling materials, by skiving or splitting the underside edge margin of the toe portion of the insole. The
skiving or splitting preferably extends over the 0 ball portion of the insole up to approximately the shank and heel portion. The toe portion and shank and heel portion of the insole are preferably divided, whilst sheeting of vulcanite, vulcanized board or similar material is inserted between the separate layers so as to form a threeply toe portion and shank and heel portion, these portions being connected together by a solid ball portion.
According to another aspect of the invention an insole for use in the manufacture of boots and shoes consists of a three-ply toe portion and shank and heel portion interconnected by a solid ball portion, the thickness of the toe portion, and preferably also of the ball portion being .3 marginally reduced to leave a projecting portion which constit tes an equivalent to the usual bottom filling materials.
The invention will now be described with reference to the accompanying drawings, wherein Fig. l is a perspective view of a piece of leather shaped in the form of an insole.
Fig. 2 is a perspective view of an insole of which the toe portion and the shank and heel portion have been divided.
Fig. 3 is a similar view to Fig. 2 wherein sheeting has been inserted in the divided toe portion and shank and heel portion.
Fig. 4 is a perspective view of insole.
Fig. 5 is a perspective view of a composite insole with the marginal edge skived or split at the toe portion.
Fig. 6 is a perspective view of an insole of which the marginal edge has been skived or split 55 along the toe portion and ball portion, the skived a composite attests PArsnr orgies margin having applied thereto an adhesive coating or a fabric coated on both sides with adhesive, the outer layer of adhesive being covered by a protecting covering Fig. '7 is a similar view to Fig. 6 in which the 5 insole is provided with a metal shank stifiener.
Fig. 8 is a perspective view of the insole mounted on a last and having the upper partly secured thereto.
Fig. 9 is a view similar to Fig. 8 with the upper almost completely lasted to the insole, and
Fig. 10 is a cross-sectional view of an upper lasted to an insole.
Referring now to the accompanying drawings a solid piece of leather is shaped in the form of 15 an insole E as shown in perspective View in Fig. l. The insole l is divided horizontally at the toe portion and at the shank and heel portion as indicated at 2 and 3 in Fig. 2 leaving a solid ball portion 4 between the divided toe portion and shank and heel portion. Into the divided toe portion and shank and heel portion there is inserted a sheet 5 of thin vulcanite, vulcanized board or similar material. The three layers at the toe portion and shank and heel portion are suitably dressed with an adhesive and pressed into a solid member as shown in Fig. 4. There is thus formed an insole which is formed of three ply material at the toe portion and shank and heel portion with a An insole thus produced has the advantage of being extremely thin and at the same time possessing a high degree of strength and solidity at the toe portion and shank and heel portion, thus preventing spreading and distortion of the shape of the boots and shoes during manufacture and whilst being worn. At the same time flexibility is retained at the point at which flexibility is required, that is to say produces greater comfort whilst the boot or shoe is being worn.
The insole thus produced is then subjected to a splitting or skiving process for the purpose of marginally reducing the thickness on its lower surface indicated at '5 in Fig. 5. This marginal reduction of thickness is effected for a distance of /2" to from each edge of the toe portion, known as the lasting margin, thereby leaving a central projecting portion i. This projecting portion l subsequently serves to form the equivalent of bottom filling materials which have hitherto usually been used at a later stage in the manufacture of boots and shoes. By the provision of the projecting portion l the use of bottom filling materials and the process of bottom filling are thus dispensed with. The lasting margin solid ball portion 4. 30'

be applied.
For the purpose of rendering the projecting portion 1, which extends from the toe portion to the solid portion 4, more flexible it is provided with a series of transverse and intersecting incisions extending at different angles as indicated at H in Fig. '7.
The linings of uppers to be attached to an insole as above described are so designed as to 40 leave approximately to of the flesh side of the upper extending beyond the lining at that part known as the lasting margin. Consequently the lining requires less material than hitherto whereby a saving in lining material is effected.
For the purpose of attaching an upper to an insole in accordance with the invention, the
. insole is attached to a last I 2 (Fig. 8) in the usual -way. After the insole has been fixed in position the Cellophane or like covering 9 is removed so as to expose the adhesive layer 8 or the adhesive surface of the strip. An upper i3 is now pulled over by hand or by the usual machine fastened to the insole by hammer blows at points I4, l5 and IS in Fig. 8. The toe portior the upper is then completely lasted to the in: by hand or by the usual machine method as dicated at IT in Fig. 9. Thereupon the forep of the upper, generally referred to as the var is lasted to the insole by hand or by the 118i machine method as indicated at I8. The sha portion of the upper is also lasted to the ins as indicated at It by these methods.
As the upper is secured to the insole by adl: sion there is no necessity for using tacks, -na
v or staple wire and the machines used for the pu pose of applying the upper to the insole are n ted; with a hammering device instead of wi' tacking mechanism.
The lasting of the heel portion 20 is also e fected by hand or by means of a lasting machir in the usual way.
Fig. 10 shows a section of an upper which ha been secured to an insole in accordance with th invention. The upper is indicated at E3 and th last at l2 and the insole at l. The skived margi of the insole is indicated at 2|. The lining 22 o the upper is lasted over to a distance of approxi mately 4;" as indicated projecting portion 1 which is formed integral with the insole.
The outer soles can now be attached or fastened to the shoe in the usual way, that is to say either by sewing or by means of adhesive.
Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is:
and heel portions of said insole.
