FRANCIS FLvNN, or WooNsocKnT, RHODE ISLAND.

Letters Patent No. 96,412, (letal/November 2, 1869.

IMPROVEMENT IN SOLES OF RUBBER. BOOTS AND SHOES.

The Schedule retorted to in these Letter Patent and making part of the same.

To all whom it may concern 4:

Be it known that I, FRANCIS FLYNN, of Woonsocket, in the county of Providence, and iu the State oflthode Island, have invented a new and useful Iulprovement iu Boots and Slices; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had'to the annexed drawings, making part 0f this speeitication, iu which- Figure 1 represents a longitudinal vertical section of suck portion of a rubberboot as is .necessary to` illustrate my improvement.

Figure 2 is a section in line x x of fig. l.

The nature of my invention consists in providing rubber boots, shoes, and such like articles, with a leather sole, while the rubber is still in the plastic state, andat'terward subjecting such shoes, boots, 85e., together with the leather sole thus attached, to the vulcauizing-process. v

Hitherto it has been considered infeasible to fasten a leather sole to rubber boots, shoes, Sac., before they had been vulcanized, because it was believed that the heat required for such process would inevitably destroy the qualities ofthe leather.

After many experiments I have found that oak leather is an exception lto this rule, and that it will stand such heat without loosing its qualities.

lo enable those skilled in the art to make and use my invention, I will 'proceed to describe its construetion.

In the annexed drawings- A represents a rubber boot;

B, theheel;

C, the leather sole; and

D, a metal plate, embedded in the heel.

These parts are constructed and united together in the fonowing manner:

^ day of August, 1869.

The heel is-ilrst prepared and vulcanized, having suitable recesses formed iu it t'or the reception ot the tongue ofthe leather sole and the metal plate.

' This latter is then placed in the heel and upon it the tongue of the sole, the plate having tilst been tapped in the proper pla-ee. The rubber sole ofthe hoot is then tbrlued by spreading a sheet of sufficient thickness, of prepared gum, upon the leather sole and the heel adhering thereto.

lloradditioual security the' leather' sole may then be screwed to the rubber sole, as shown in the drawings, or it may be tacked or sewed thereto, ik' preferred.

It is desirable to use a screw iu. the heel, penetrating the rubber and leather sole, and screwing into the metal plate, so that the heel may be moretirmly secured.

The tbrmation of the boot, shoe, Ste., is then to be I completed, at'ter which it is placed in the vulcanringl heater and properly vulcanized. ished in any approved manner.

Having thus described my invention,

What l claim, and desire to secure by Letters Iatent, s

Attaching oak-tauned leather soles to soles of rubber boots and shoes, substantially iuythe. manner described, aud then causing them to adhere to rubber boots and shoes by the ordinary means of vulcanizetion.

The above specification signed by me, this 23d FRANCIS FLYNN.
