METHOD or MAKING TURN sHoEs. l

Application led'J'anuary 7, 1924. Serial No. 684,699.

Turn shoes are now commonly manufactured under what is known as the string system in which the various operations are divided among several operatives, Veach of whom performs one operation, orL if the operations are minor, two or three, and then passes the shoe to the next operator in the proper sequence. Y

The shoe sole must be in temper when first tacked to the last and must remain so unt-il after the final sole shaping operations have been performed thereon, which commonly is not until a considerable number kof other operations have also been performed. This causes a considerable time interval to elapse between the first and last operations in whichl the sole must be in temper, often as milch as an hour and a half being expended in these intermediate operations and in passing from one operative to t-he next so that this time elapses between the sole vtacking operation and the time when the shoe may be .permitted to dry out. It has. been found impracticable to retemper the soles of shoes which have once become dry, as this injures t-he upper and is quite likely to stain the linings, and consequently shoes, the assembling of which on the last has been commenced, must be carried through the operations until such time as the temper of the sole is no longer required as soon as possible so that they may still be in temper for the final operation requiring it. They can not be left over night when in any intermediate state as they would not remain that long in temper and would be unsuitable for carrying out the required operations on the soles on the succeeding day. From this it results that the operator who pounds out the soles must wait until the shoes begin to reach him after all the previous operations from the sole tacking have been effected the same day, that is, if the sole tacker starts to work at 8 oclock a. m. there may be nothing vfor the pounder out to do before 9:30 oclock. Likewise the sole tacker must stop work early in orderthat the last operation requil-ing the sole tobe in temper maybe completed on allthe shoes which the sole tacker has worked upon that day by the end of the same working day. Moreover, as some of the later operations requires a longer time than the earlier ones, the sole tacker'V must stop Work earlier'than the pounder out by a greater time interval than his earlier start in the morning. It is not uncommon, theretions requiring the sole to be in temper is absent, since if he can not be replaced fat once all of the other operatives Within this the sole tacker to stop Work at group can not work.V This will be evident when it is considered that it 'would not do for those performing operations prior tothe absent operator to do their parts as the shoes would then dry out after being partly completed and would be unfit for the later operations, and there is no work left over from the previous day in condition for perform-V ing the later operations.

Heretofore, also,.when the shoes are being dried they are still onthe they have been drawn in .the'relasting operation so that theV air does not have free access to the interior of the shoes. It commonly requires as much as five days from the sufficiently dry for the lasts to be removed,

and consequently a very large number ofr each is substantially equalized. The com-- paratively short time required causes the temper of the sole to be` more uniform for the different operations requiring it and permits a longer working day for the individual lasts over which `timeof relasting for the shoes to become' operator without lengtheningl the operating time of the factory. This lresults in a greater output of finished shoes with the same factory equipment and personnel, more efficient operation of machinery and reduced overhead expense. vMoreover, the relatively f few operations required` to be performed while the sole is in temper greatly lessens the chance for the absence of one operator stopping the Work ofothers and decreases the number of others who are affected incase one should be absent. i Y

Moreover, as will later more fully appear, in carrying out the methodfof this invention, the soles are shaped quickly by machine without requiring special skill on the part of the opei'atoi'and to a more perfect form than can be produced by the hand 'pounding out method which requires considerable skill and a much greater expenditure of time.

Further advantages will appear from a more complete description of the method with relation to the accompanying drawings in which Y v Figure 1 illustrates the shoe as assembled 0n thellast. 1

This invention relates to a modification of the vgeneral method of making turn shoes,

particularly described and claimed in my Y. Patent No. 1,537,419, granted May l2, i925,

for turn shoes.. The process as disclosed in -this patent is' as follows. The sole and upper `are assembled on the last wrong side out,

the i sole being in temper, and they are stitched together in the usual manner, the

partially made shoe 'at' this time being provided with neither a boX toe nor a counter stifener. The last is then withdrawn-from Y the shoe and the Vtoe portionof the shoe -end of the shoe between the lining and Ycap of the vamp, the lower edges ofthe hntuined, and in this condition a previously molded box toe may be inserted in the toe ing havingbeen left unattaehed to the sole in thev stitching operation to permit the Vcap to be inserted in position. lf desired the toe stifener may be inserted after the sole has been? allowed to'dry. A previouslyinolded 'counter-- stiii'ener assembled with a shank Y counter, and after the counter stiffener is itis dry.

thus properly located a looseV strip of the shank piece is turned 4down to yoverlap the inturn'ed edges of the lining and the heel seatflange of the vcounter stiifener.

In the turning operation the shoe is more or less wrinkled and marred, the sole being substantially flat and with a slight curvature upwardly at the toe end. l/Vhile the lsole is still in temper, according to the patented process, it is thenV molded as between dies to finished form, particularly throughout its shank portion and its entire forepart. After the sole has been molded to form itis then permitted to dry and Vthe subsequent `operations are performed on the shoe while The present invention covers a Inodilication of this method in which instead of assembling the counter and shank piece in the Vshoe before the molding' operation, as Vdisclosed in the patent, this assembling operation is deferred until after the molding operation. rlhis necessitates a modification inthe form the moldingdies as is fully illustrated in Figure l. The die 15 is the saine as disclosed in the patent, but the shankportion of the die 20 forming the inner face of the shoe is formed withV a fairly sharp l! -shaped extension which forms a decided depression in the inner of tle shank of the sole as shownat 22 in Figures 2 and 4.- f

After the molding operation the shoe is permitted to dry and the counter and shank piece are then assembled in'position as illustrated iii Figure Preferably as is shown inthe patent thek counter stiffener is one which has been previously molded and assembled with the shank piecel2, Vthe shank piece havingbeen splitforwardly from the heel end so that after the counter is properly located in place between the lining and counter, the loose strip i3 the shank piece may be turned down so as to overlap the inturned edges of the 'liinng` and the Aheel seat flange of theV counter stitlener. While this is the preferred construction of shank piece and counter stifiiener, other constructions may be employed if desired.

This method is regardedas Jreferable to i. c l 7 that in my patent becauseV after tiie inoiding operation the shank of the sole conforms to the shank piece, whereas in the iforiner method the shank piece and sole .are not formed to lit each other when theyare attached. It furtherhas the advantage that when the counter and shank piece are being assembled,V the Aanvil block` 2B* of the nailing machine 'being prolonged forwardly to underlie the entire shank .and the rear portion ofthe forepart as shown at 24 so that wliilethe nailing-block. 25 of the nailing machine through which vthe securing nails are driven which attach the shank piece Aand counter yin position is'in clamping relation tothe anvil piece, theextension 24 of this piece forms an' anvil block against which' a tack, as at 26, driven through the forward end of the shank piece and the sole of the shoe may beolinche'd. This attaching operation maythus-be performed very readily by hand without requiring a separate handling ofthe shoe asiis required lwhere'a special operation `for this purpose is necessaiy'as in the method described in the patent. This modification alsorrenders necessary one less operation While the sole of the shoe is inY temper, thus expediting the operations requiring the sole to be in this condition. i

As herein shown the heel portion of the shoe is turned back after the molding and drying operations and before the counter and shank piece are fixed in position, the heel portion of the shoe having been already turned right side previous to the molding operation so that thc counter and shank piece may be xed to the upper face of the sole readily in the manner disclosed in the patent hereinbefore mentioned. This, however, is a very simple act since the upper only is manipulated, but if desired the counter and shank piece may be assembled While the heel portion is right side out according to the method disclosed in my Patent No. 1,665,582, granted April 10, 1928,- entitled Method of and machine for attaching counters to turn shoes. l

Having thus described this invention it should be evident that various changes and modifications may be made therein without departing from its spiritor scope as defined by the appended claims.

I claim:
