METHOD OF 'MAKING BOOTS AND SHOES.

Application filed July 20, 1920. Serial No. 397,695.

To all whom zmag/ concern:

Be it known that 1, FRANK E. ROBERTS, a citizen oli' the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful mprovements in Methods of h/laking Boots and Shoes, of whichthe following is a specification. A

My invention relates to boots and shoes and has reference particularly to the method of making boots and shoes of that class which have molded outersoles.

it has been the practice to mold the outersoles of certain kinds of vboots and shoes, particularly womens boots and shoes, so as to `term a sharply deiined angle or corner extending across the sole at the 'junction of the shank with the fore-part, that is, just back of the ball, so as to give a. pronounced arch to the shank which starts upwardly abruptly from the rear end olf the Jforepart. 1t also has been the practice to mold the shank of the outersole so that it was more or less V-shaped in cross-section with a sharply defined median ridge or corner upon the exterior thereot1 extending from the rst mentioned transverse corner or angle at the rear of the fore-part to the breast of the heel. This peculiar molding of the outersole, sometimes referred to as the Cottage Roof shape, has the advantage of improving the appearance of the boot or shoe and also of stifening the shank.

1n my co-pending application. filed August 20, 1919, Serial Number 318,771, 1 have illustrated and described a shoe whose outersole is molded to the Cottage Root shape after the parts of the shoe have been assembled upon the last, and my present invention has for its object to provide a simple, expeditious, economical and efficient method of making shoes of' this kind.

1n making a boot or shoe constructed as described in said application, the upper and innersole are first assembled upon a last and a bolstering member is placed in position upon the innersole at the place where the sharply delined bend or corner is desired in the outersole. The outersole is then secured in place and beaten down so as to utilize the bolstering member to give the desired shape to said outersole.

In making a boot or shoe in accordance with my present invention the parts may be assembled upon the last and secured together as described in said application, but the beating down of the outersole `is effected by blows or pressure delivered `onto said outersole by'any suitable instrument, preferably a rotating wheel, in the peculiar 1 fashion hereinafterA described which stretches or crowds the material ot the outersole toward theapex of the corner or bend with the result that a very sharply defined and accurately formed ridge or corner is produced.

In the accompanying drawings;

Specification of Letters Patent. Patented June 28, 1921.

Figure 1 is a perspective view of the bottom portion of a shoe having a Cottage Roof sole, said view including also a portion of Va beating down wheel which is shown by dotted lines.

Fig. 2 is a perspective view of the bolsterlng member hereinafter referred to.

Fig. 3 is a perspective view of a portion of the beating down wheel hereinafter referred to.

Fig. 4 is a sectional detail of the wheel shown in Fig. 3. i

1n constructing the shoe of Fig. 1 the upper and inner sole are lasted and sewed together as usual after which the usual filler is spread over the fore-part of the innersole between the edges of the upper. 1 next place upon the innersole, immediately at the rear of the filler, a holster member 9, Fig. 2, said bolster comprising a strip 14 extending more or less obliquely across the sole at the rear of the fore-part thereof and a stem 15 extending lengthwise of the shank 7 at the middle thereof. An unmolded outersole is then placed in position and sewed to the up per and welt in the usual fashion after which the outersole is trimmed.

The rear end of the iforepart and the shank 7 ofi the outer sole are then beaten down to shape them to the last and also bend or fold the sole sharply around the bolster member 9, the strip 14 of the latter producing a sharply delined bend or corner 6 upon the exterior of the sole extending somewhat diagonally across the latter, and the stem 15 of said bolster member giving to the shank a V-shape in cross-section with a sharply defined ridge 8 at the middle of the exterior of the shank which extends Jfrom the bend or corner 6 to the breSt of the heel,

In proceeding' according to my presentin- Vvention the beating down oftheoutersole is effected by After the-upper, inner sole,bolster mem-V bers and outer sole have been assembled upon the last, and the inner and outer' soles last g, then placing a Ahave beensewed te the upper, theV shoe, still upon the last'is` manually presented, .as shown in F ig. l, to a rapidly rotating wheel l2 formed witharoughened or corrugated periphery v13 and is shifted about relatively thereto'so thatthe elevationsot said periphery deliver a succession of glancing or wiping blows upon the tread side of the outersole asindicated by the arrows. The

wheel l2 is, causedto traverse both sides of corners 6 andA ridge 8, the workman grasping the `opposite ends of' the shoe vwith his hands and pressin said shoe against wheel l2zwith `his hip.` he shoe is'presented to wheel 12 sov that each peripheralV elevation of the wheel strikes the'V outersolelat one side iof the line of the corner 6, er ridge 8 that is being formed and wipes or slides on 'the sole toward said line. This method oiV procedure beats the outersole down againstthe last and bolstering means and Valso crowds the material of theoutersole more 'or less toward the corner 6 and ridge 8 with the resuitV that the latter are very accurately produced and `sharply defined. Moreover, this method is expeditious and economical, as' by ita skilled workman can completelyniold the sole of a shoe of avery few seconds.

The method of making boots and shoes of the class described whichconsisvts in Vfirst assembling the upper and'in'ner sole 'upon a bolstering Vmember inY position` upon the innersole; then securing the outersole in place, and lastly beating dowiithe outersole so asto shape the latter to the last and bolstering membcrby crowding the material of the outersole'toward said bolstering member and the Vlast'simultane-` ously.
