t V11- Claims. (Cl. 36-25) 'I'his invention relates to improved outsoles for shoes.

One object of the invention is the provision of an outsole which possesses a high degree of. flexibility at least in the forward portion thereof, say from the shank to the toe of the shoe, without, however, requiring the use of thin leather? or thin leather substitutes. In other words, in accordance with the present invention the outsole may be of substantial thickness and yetpossess great exibility in the direction of the length of the shoe.

Another object of the invention is to provide an outsole formed of orcomprising at least in the forward portion thereof a plurality of strips of suitable material disposed in adjacent side by side relation and extending transversely of the outsole and secured in said relation whereby at least said forward .portion of the outsole is easilybendable about a plurality of transversely extending lines.

-A further object of the invention is to provide a rope sole of such construction that it' can be readily produced by die-stamping or otherwise cutting the same from sheet material, making it unnecessary to produce the rope sole by winding a length of rope in order to form the sole.

The above and other objects, features and advantages of the invention will be fully understood from the following description of the presently preferred embodiment of the invention. reference :u being had to the accompanying illustrative draw.

Fig. 4 is a plan view of the sheet material utilized in producingthe outsole illustrated -in Figs. 1 to 3, the dotted lines showing the manner of cutting the outsole blanks from said sheet material,'and

Fig. 5 is a View similar to Fig. 4. showing a modification.

'Referring now to the drawing in detail, there is shown in Fig. 1 a shoe Ill having an upper l2. an outsole I4 and a mid-heel I6 of the wedge type, said outsole extending from toe to heel of the shoe in substantially a single plane. It will be understood that the style of the shoe may be different from that illustrated and that the shoe may be provided with any type of heel.v As the invention resides primarily in thev outsole and in said strips, respectively. Said strips I3 are prefy the material used therefor, these aspects of the invention will now be described.

The outsole, as here shown, is formed of ,braided rope and comprises in themain part Ma thereof a plurality of strips IB of braided rope disposed in adjacent side by side relation and extending transversely of the outsole and secured in said relation preferably adhesively by layers 2liv of latex or other rubber interposed between the adjacent sides of adjacent strips i8 for the full length of erably formed of braided rope and are greater in width than in thickness and are disposed in the outsole so that the widthsof said strips extend in the direction of the thickness of the outsole. that is, in the direction extending between the opposite'A surfaces of the outsole. layers 20 of latex or other rubber are confined substantially to the spaces between the adjacent sides of adjacent strips and between the opposite surfaces of the outsole. Said latex or rubber is applied to both sides of the strips for the full length thereof and may be applied either in liquid or semi-liquid form or in plastic condition, and it will be understood also that the said latex or rubber may be applied to the strips by a frictioning operation, for which purpose any conventional 'or other suitable frictioning rollers may be used. The rubber may be applied for the full width of the strips but is preferably kept from the marginal edges extending longitudinally of the sides `of the strips so that the oppositesurfaces of the outsole will be substantially free of rubber.

While the rubber impregnates a su'lcient thickness of each strip adjacent the opposite surfaces thereof which are disposed in side by side relation in the outsole, whereby to obtain a secure union between adjacent strips. the major part of the thickness of each strip is preferably not impregnated with the rubber, so'that the porous character of the strips remains substantially unimpaired. Y'

It wm lbe observen-nat stops la in main part.

or blank Ha of the outsole vary in length depending upon their location along the length of the outsole and are disposed in the outsole so that the opposite edges of said strips. considered as a unityconform to the peripheral edzfe contour of the outsole. A covering strip 22 of braided rcpe is applied to the opposite edes of strips i8 and as here shown extends completely around the outsole. Strip A22 is4 preferably formed of braided rope of the same construction as strip I8 but if desired may be formed of any other suitable material. Said edgingr strip 22 is The interposed secured to the edges of strips I8 by a layer 24 of latex or rubberinterposed between the inner side of strip 22 and the adjacent edges of strips I8. As here shown strip 22 is formed in one length and has its edges located at the inner side of the outsole in the region of the shank as indicated at26 in Fig. 2. While as here shown out. sole III comprises strips I8 disposed therein for the full length of the outsole, it is within the scope of the present invention to form only certain parts of said outsole from said strips, for example, the forward portion of said outsole, namely, the part thereof extending from the forward part of the shank to the forward end or toe portion of the outsole, since the advantage f flexibility is valuable principally in the forward portion of the outsole while the shank and heel portions' thereof can be stiff or comparatively stiff. Preferably, however, as here shown the outsole is of uniform construction as this facilitates the manufacture thereof and of the shoe provided therewith, and especially since the various parts of the shoe which are advantageously rigid or stiff can be provided with shank stiffeners or other devices with which the shoe-manufacturing art is familiar.

The main part Ma of the outsole embodying the present invention, as described above, that is, the part which is constituted by said strips I8 united with each other in said side by side relation, is made from the sheet material M illustrated in Fig. 4. As here shown, said sheet material M comprises a plurality of lengths l8a of braided rope extending longitudinally of the sheet in side by side relation and secured together in. the sheet in said relation by interposed layers of latex or rubber as described above in reference to Fig. 3. In other Words, the strips I8 united with each other as described above are derived from lengths |80. `of sheet M. This is accomplished by die-stamping or otherwise cutting the main part or outsole blank Ma from sheet M along spaced lines extending transversely of said sheet wherebyvthe outsoles are provided with the united strips I8 which extend transversely of the outsole. `Said sheet M is of sufficient width to permit the outsole blanks or main parts I4a to be cut therefrom with the lengths of the outsoles extending transversely of said sheet.

' While said sheet can be substantially wider than the lengths of the outsoles, said width need be only equal to or slightly greater than the length oi the outsoles to be cut therefrom. Moreover, it will be understood that said sheet can vary in width depending-upon the lengths of the outsole to be eut therefrom and that 'said sheets can be supplied in various minimum widths or can be supplied in widths which are large enough to permit soles of the longer lengths as well as of the shorter lengths to be cut therefrom. Further, it will be understood'that while the sheet `M has been illustratedas Wide enough only for a single row of outsole blanks, it may be of any desired greater width so that a plurality of rows of outsole blanks can be cut therefrom. y

It will be understood that after the outsole blanks Ida are cut from sheet M the edging strips 22 are applied to said blanks, respectively, as described above. Preferably, the outer side of edging strip 22, especially when the latter is formed of rope, is free of adhesive or any other coating or covering material so that the ornamental appearance of said edging strip is'provided in the shoe comprising said outsole. Afterthe outsoles are made they are attached to the shoe bottoms in any suitable way, preferably 1n accordance -with any of the conventional methods of making cemented shoes. Further, it will be understood that the sole blanks I4a can be at-` tached to` the bottoms of the shoe before the edging strips 22 are applied and attached to said solev blanks.

While in Fig- 2, the strips I8 are shown arranged at right angles to the longitudinal median line of the sole, said strips can be arranged at a different angle to said median line, especially when it is desired to produce a sole which is less flexible than when said strips are insaid right.. angular relation. This can be easily accomplished by cutting the sole blanks from the sheet M in the manner illustrated in Fig. 5, i. e., by cutting the blanks indicated at Mb so that the longitudinal median line 26 of the sole blank is inclined at the desired angle to the longitudinal line of sheet M.

Thus, it is seen that the-above described outsole and material utilized in making said outsole are well adapted to accomplish the several objects of the present invention. It will be understood, however, that while I have illustrated the preferred embodiment of my invention the latter may be embodied otherwise than as herein specifically shown or described, and further it will be understood that in the illustrated embodiment certain changes in the details of construction and in the arrangement of parts may be made. Therefore, I do not wish to be limited to the invention as herein specifically illustrated or described except to the extent which may be required by the scope of the appended claims.
