l/l//T/vgsssfs To aN whom it comme?.

Be it known that Bientina E) .zo'inj n cinizen of the United States, resid Boston., county oi Suffolk, State of fussziehusetts, have invented certain new and. use fui mpi'ovements in the Metiio of Making and neorporating Stiiiening--Pieees in the Foiepert of Boots and Shoes.

My invention relates to the nianufiiofbure of been; and shoes of the type wherein ehe toe parte having box toee :ire formed di the process of lasting which bmi Dees hei/e a, siening piece incorporated ther-ein pnbie of being moided into the desired Shape during the lasting operation. y

The object of the invention is to produce e stiiiening piece for a. box 'me which wiii be durable, not effected by moisture, and not aifeeted or softened by a ciegiee oi? heet which might be injurious to the materiel oi the upper of the boot 01' shoe; and fiiitiiei, to provide for heating the stiii'ening piene to soften it after it is dry and incorporated in the upper oi e boot oi" shoe by applying the heat in such manner as not io ing'uz'e seiEA upper.

In Carrying out the invention provide e blankV of absorbent, iibroue or 'textile fais ric, capable of 'absorbing a stiifening iiiid ei. composition. A. suitabie eompesiion er Huid may be made effe solution of Sheila@ and alcohol, to which may be :aided :i sin@ cient quantity of borax solution :and eiiii'ii dissolved in Water. When desii'e, the alum may be left out and buty ii simili quantity of borex added to the sheilac in order that the composition may be inactif ',enily Waterproof and so the@ it Wiii reqniie degree of heej, in excess of @he boiiing point o soften the stin'eitnng piece se 1; een be moided into the desired shape.

other method of heating may loe used, such as gas, eteem, or other means which will generete suiiicient heet to soften the sti'ennog piece l.

v:in carrying out my method o making end incorporating o stienirig piece in e boot or Shoe, i provide the heet e' 9 with the inem .loting pieces l0, i0, the heater being provided with suitable supports, es il, 1i, to reise it, so that for convenience the lesti-Q may project eiigiitly under 'the heater. The Ilest may be supported upon e rock 3 3 so es to bring the toe-port of the `ooot or shoe upper to e position where the stiileniug piece 1 may loe easily inserted in the heater. ln, the heater shown, le is the body part of the heater, which may be en incloeed metal body ond which may contain the heating coils l5, .3.5,- etc. li eieo provide Wire protectors lo, 16, etc., to guide the .etiening piece i and to prevent it from coming in contact with tlie y heating surface of the heating coils l5, l5,A

'Elie guards l0, l?, maybe mede 'of any suitable non-conducting 1r1oteriel,e11cl1 ee osbestos end the likeg Ae before stated, Il do not confine the stiening iiuid oi composition AWitli which the toerpiece is saturated to siiellec, or Shel lac and borex, or shellec, berm; and alum composition, es any other suitable Weterproof, end loeheotproo composition mey be used for stiifeniiig the fibrous materiel, or textile fabric; nor do confine my invention to en. electrical heater, or the exact form of un electrical heater shown in the drewing, when. euch type ot' heater is used, es any ormof electicel heater may be used which will generete e suiiicient omountoit' heet to soften the stiiening vpiece; and further, other forms of heating devices, such es steam', or o gas heater, may be need. My in volition resides particularly' in providing composition that will be practiealiy Water roof and that eviil not eoiten up under the ordinary degree of heat; such for. instance, if the wearer of e boot or Shoe should hold his foot close to or against e, steam redietorq Liemeer) the heat generated iii such case. would not ice sufficient to soften toe toe-piece` Further, 'l provide means for softening the toe-piece so lit can be molded Without liability to irlg'ure or overheat the lining or toe-piece of e shoe.

1. The method of making stiieeed foreparts of boot and shoe uppers, which consists in incorporating in the boot or shoe upper before lasting, o dry stileniig piece composed of a ibrous material containing stiilening composition or materiel adapted to be softened by a, degree of heat, which might be injurious to the boot or shoe upper and lining; heating the stiiieniug piece to soften it and .protecting tlie upper end lin ing from the heat; 'thereafter molding the stilienin piece to the form. of the toe portion of tie lost While it is soit, by the opere tions of pulling over and lasting and ellow ing the stiiiening pieceto cool and permenently retain its molded form;

2. The method of making stiiiened box toes of boot and shoe uppers, which consists oft making e stieniug piece composed of iibrous materiel containing e stiiieniiig composition or material adapted to be` softened by heet of o degree which might be injurious to the 'upper and lining; fasteiiing the stiii'ening piece to the upper; turning back the upper from the stiiiening piece to protect it from the heet; heating the stiening piece by o comparatively dry heet to render it soft and yielding; thereafter molding the stiiieiiing piece to the form of the toe portion of the last While it is soft by the operetioii of pulling over 'the upper and allowing the stiii'ening piece to .cool end permanently retain its molded form.

iin testimony whereof, l lieve hereunto set my hand, in the presence of two subscribing Witnesses, this the 10th dey of December,
