lUNITED STATES PATENT OFFICEO LYMAN DAGGETT, OF BOSTON, MASSACHUSETTS.

.HVIPROVED ,INNER SOLE.

To all whom t may concern:

Be it known that I, LYMAN DAGGETT, of

Boston, in the county ot' Suffolk and State of Massachusetts, have invented a new and useful or Improved Inner Sole for Boots or Shoes 5 and I do hereby declare the same to be fully described in' the following specification and represented in the accompanying drawings, of which- Figure l is top View, Fig. 2 a bottom view, andV Fig. 3 a transverse section, of it.

It is composed of a sheet of india-rubber', A, or other suitable equivalent, and a lining or covering, B, of cloth orleather. It is puuctured with numerous holes, a a a, going through it at regular distances apart. I prefer to arrange them as represented in Fig. 1. The lower surface of the sheet of rubber is to be made with projections, as shownA at b b, and with cavities or passages o extending between or between and around the projections, Iand communieatin g with the holes a, which go down through vthe sole and between the vsaid projections.

These projections serve, while the sole is in use, to support it on the inner sole of the shoe or boot. The passages or cavities allow air to freely circulate underneath the false sole and up through the various holes in it. The false sole is thus elastic and ilexile. It insulates the foot of the wearer from the sole of the shoe, so as to keep the foot dry in case the sole becorne wet. By allowing air to circulate under and through the sole, perspiration of the foot can go on freely without injury to the foot or damping the stocking. Besides this, the sole constitutesan elastic body, which is soft or yielding to the foot and serves to relieve it or its joints from the effect of concussions of theV shoe while the wearer may be either walking or runnin g on pavements or a hard ground or surface.

It' desirable, the sole may be xed in so as to forni part of a boot or shoe. I ela-iin as my invention- The tlexile inside water-proof elastic soleas made with the supporting projections eX- teuding from its lower surface, and With passages around and between such, and holes leading therefrom up through the sole, the whole being substantially as described.

.LYMAN DAGGETT.
