COUNTER-STIFFENER Specification of Letters Patent.

Patented Mar. 31, 1914.

Application ined May 29, 1911. serial N0.l 630,255.

'0 all whom it may concern Be it known that I, GEORGE L. PREBLE, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements iin Counter-Stiffeners, of which the following is a specificat1on.

The present invention relates to counter stiffeners for boots and slices, and consistsy in a number of improvements upon the counterstiiiener illustrated and described in Letters Patent Number 866,732, granted me September 24, 1907. The essential feat-ure of the counter stiifener forming the subject matter of the aforesaid patent is a thin sheet of Celluloid molded to the required shape and interlocke-d with the fibers or stra-nds of' a sheet of reinforcing fabric. In that patent the sheet of Celluloid and sheet of reinforcing fabric are of the vsame shape sive. Considerable ditliculty is experienced in 'attaching t-heforward edges of the counter stiflener to an insole by the row of stitches vwhich attach a. welt strip. This ditliculty is due to the stiffness of the Celluloid.

One of the features of the present invention is the provision of flexible tabs formed conjunction with a sheet of Celluloid. The sheet of Celluloid is So cut that its forward ends Will not extend into the path ofthe needle of the sewing machine by which the wel-t strip is attached, but the sheet of rcinforcing fabric is extended beyond the sheet of Celluloid and is therefore extremely flexible and may be seated closely in the angle of the shoulder Iof an insole. The ends of a welt strip usuallyv overlap the forward edges of a counter stiifener about one inch, more or less, and when the counter stitfener is rovided, as in the present instance, with softlflexible tabs at the point of overlapping, a joint may -be made which is less bulky Athan if the sheet of Celluloid extended Another v4featurevvof theprCSent invention is the provision of a double blank of reinforcing"`fabric which is folded so as to provide two thicknesses to inclose the sheet of Celluloid.

Uf 'the accompanying drawings which illustrate't-he invention: Figure 1 represents aperspective view of a counter stiil'ener in position upon the heel portion of an insole. Fig. 2 represents an'inverted plan View of the molded counter st-if't'ener, a portion of the reinforcing fabric being broken away to expose the interior structure. Fig. 3 repre sents a cross-sectional view of a portion of a shoe in process of construction. Fig. et represents a plan View of the several blanks of which the Counter stifiener is composed. Fig. 5 represents a counter stiilener consisting of a st-ifi'ening member inclosed between two layers of reinforcing fabric before being molded. i

The same reference characters indicate thc same parts wherever they occur.

Referring first to Fig. Li, a blank of reinforcing material is indicated at 10.v A blank of Celluloid is indicated at 11, and a blank of stiffer and stronger material, such as wood liber or leatherboa-rd, is indicated at- 12. The blank 10 is composed of text-ile material. Flannel and felt are found to be desirable for reinforcing material. The sheet of Celluloid and the sheet 12 of relatively stiff material of the outlines shown are laid upon the blank 10, which has but a single thickness, in the condition shown by l? ig. 4. With the several members in the relation shown, the blank 1() is folded along its longitudinal cent-ral line 13 so as to inclose the

members

11 and 12 between two la J ers of reinforcing material. The blanks are then subjected to a molding process to give the article the desired shape, as shown by Figs. 1 and 2. A suitable solvent is applied to the Celluloid to render itI soft and sticky 'so that it will be ii'iterlocked with the

members

10 and 12 as the result of the molding operation. If a liquid solycnt is used'it will be applied to the Celluloid prior to the molding operation7 but ifheat is to be used asa solvent it may be applied during the molding operation.

It will be observed that the ends of the celluloid 11 are cut away at an angle to the inner edge thereof, as indicated at 14, 14. The purpose in cutting the celluloid to this shape is to provide soft

flexible tabs

15, 15, of reinforcjn material 10 at the forward extremities o? the counter stiff'ener. These its 15 serve to attach the counter stiffener ;c other parts of a shoe :c when the upper '1nd welt thereof are sewed to the insole. An insole is indicated at 16, an upper is indicated at 17, and a welt strip is indicated at 18. The ends of the welt strip usually overlap the endsv of the counter stiflener for a distance of one inch, more or less. 'When the counter stifl'ener is assembled with the other parts of the shoe, it is interposed bef tween the lining 19 and the upper 17, as shown by Fig. 3. The welt strip 18 is laid .upon the upper and the several thicknesses `are united with the insole by a row of stitches, as indicated at 20. The celluloid 11 and stiffening member 12 are not directly united with the insole by the stitches 20 because of the manner in which they are cut away. The tabs 15 are therefore adapted to be drawn snugly into the angle of the insole formed by the shoulder 21 and feather 22. The doubling of the reinforcing material 10 avoids loose ends of threads and provides a smooth inner edge for the lip 23 which engages the heel seat of the insole. The doubling of the tabs 15 also facilitates the sewing operation. The soft tabs 15 may be readily tri ed after the sewing operation has been fi ished.

lVhile a more efficient counter stiffener may be produced by the use of a sheet of celluloid 11, the celluloid may be omitted from counter stifl'eners for shoes of inferior quality, leavin the counter stiffener having only the flexib e material 10 and the relatively stiftl member 12, as shown b Fi 5. In this figure the material l0 is olde to provide two thicknesses, and the member 12 is inclosed between the thicknesses. The formation of' t-he stiflening member 12 provides the soft flexible tabs 15 as previously described. This counter stifl'ener may be molded in the usual way and may be attached to a shoe in the manner explained just as if it contained a sheet of celluloid. When the celluloid is used, the counter stiff.- ener is preferably molded so that the celluloid will lie between the stifeningmember 12 and the foot so as to serve as a moistureproof barrier between the foot and the stiffening member.

While the counter stiffenergin the forms illustrated has been described with part-icularity as to the materials used and as to the 'doubling of the soft fabric, I do not wish to limit myself in these particulars.

The essential feature of the invention still' material between said celluloid and one of the layers of said flexible material, said layer of stiff material being smaller than said layer of celluloid, said layer of celluloid being interlocked with said layers of flexible material outside the margin of said stiff material, and said flexible material extending beyond said celluloid to provide flexible tabs adapted to be sewed in with the between substance of a shoe b stitches which do not pass through the ce luloid.

2. A counter stifiener comprising a member of stiff sheet material having a heel-seat flange, and a covering therefor consist' of a member of soft flexible sheet materiel?, said covering having a crease and two confrontin layers connected by the creased part, said stifl material lying between said layers and said creased part inclosing the inner edge of said flange, said inner edge being substantially coextensive with said crease around the rear portion of the flange a substantial portion of the length of sai inner edge at each end of said flange being a sufficient distance from said crease to enable a needle of an inseam sewing machine to sew the inseam stitches through both layers of said soft flexible material between;`

said crease and the inner portions.

3. A counter stiflener comprising a layer of relatively still` material having a heel-seat flange, and a doubled sheetof soft flexible material, said stiff material being between the layers of said soft'flexble material, and the crease of said soft flexible material inclosing the inner edge of said flange and diverging from the edge of the flange to provide soft flexible tabs between the ends of said heel-seat flange.

4. A counter stifener comprising a doubled sheet of soft flexible material having an upper body portion and a heel-seat flange the crease' of said soft flexible material being at the inner edge of said flange, and a layer of relatively stiff material having an upper body portion and a heel-seat flange at the rear and sides, said layer of relatively still` material being between the layers of said soft flexible material, s'aid edge of said end flange of relatively stiff material being shorter than the body irtion thereof and secured to said upper and insole by said shorter than said flange c said soft Hexible stitches. 10 material.
