Application filed September 28', 19,11.`- .Serial No. 651,694. i

T 0 all 'whom it may concern Be it known that I, GEORGE L. RoLLiNs,

of Bridgewater, in the county of Plymouth forced by a stay of any material suitable for the purpose, for instance, a-textile fabric such as duck or other cloth, or other nia terial. l

My particular object is to supply a want which has Vnot as yet been met by reinforced iiiner soles as heretofore inade,1iiamely, to

supply a sole having the desirable character` istics as followsz--irst the full stiffness and strength of the stock in its original condition at the edge of theinsole; secondJa flat and smooth surface over .the entire area bounded by the rib; third, additional reinforcement at the rib; fourth, the abscnge of a groove or gutter on the face of the sole opposite to that from which the rib proje` and following the course of the rib. in;v short it is my ob]ect to combine all ot these 30 .features in a single sole.

same parts in all the figures. ,i

` Referring to the drawings, a represents an inner sole which is ordinarily made of leather, but sometimes made lof leather 4 board,pasteboard,or some such material less expensive than leather. Formed integrally on the sole is a lip or rib b provided to receive the stitches which unite the upper leather and welt strip to the inner sole. This lip ory rib is formed by cutting a chan- `rih and the bottom of the channel c..

nel, represented by1 c in the face of the sole,

Land turning up that part of the material of the sole which lies over the channel, at right angles to thc plane of the sole. nel c is cut from a line welll within the edges of the sole, following the outline' thereofI more or less closely, andextending part way only to the edges. In othef' words, the inner limit of the channel is distant from the edge of the sole an amount equalito the height of the rib plus the extension` qf the sole`outside Vof the rib.' The rib is thus formed entirely of material cut from .they face of the sole The chan-` Y back-yor insideof the base of the rib. The

reinforcing strip or stay strip d, preferably of some such textile fabric as duck, is lai;l in ,the angle between the inner face of the The width of the strip is approximately 'equal to the height of the lip plus the width of the channel. and its thickness is about equal to the depth of the channel. It thus lies in the channel practically tillfing the same, and
