INNER/SOLE. 7

Application fi1ed March 28, 1923. 'Serial No. 628,260.

This invention has relation to innersoles;

for welt footwear of the general character illustrated and described in my Letters Patent No. 1,420,461 and No-'1,393,730,dated June20, 1922 and October 11, 1991, respec- I tively. e

In a shoe, such as illustrated in these patents, the innersole comprises two members at the shank, one of which is stitched to the welt and the other of Which isloose or free from the welt, thereby making the shoe flexible and comfortable to the wearer. More particularly the innersole, which forms the subject of this specification, is split at the shank so as to provide the two members which are integrally connected along'a line transversely of the innersole at approximately the ball thereof or at the juncture of the shank with the forepart of the innersole.

The object of the invention is to provide a split shank innersole with a rib. which is shoes.)

reinforced at the shank,the invention comprising the innersole and the method of making it. I

On the drawings, I have illustrated the several steps which may be followed in forming an innersole in accordance with my process and for producing an innersole embodyv ing the invention.

Figure '1 represents an innersole, after the first operations have been-performed there on, to provide the innersole with an upstanding rib extending from the heel around the shank and the forepart back to the heel again.

Figure 2 represents the innersole after the forepart thereof has been subjected to an inner channellng operation.

Figure 3 represents the innersole after it has been split and the reinforcing members have beenturned up at the shank.

Figure 4 represents a longltudlnal section on the line fir-4 of Figure 3. j

Figures 5,. 6 and 7 represent sections on the lines 55, 66 and 7-7 of Figures 1, 2 and 3 respectively.

(The innersole represented in the foregoing figures is preferably adapted for mens Figure 8 represents an innersole blank after being subjected to the first operations of-forming and turning the rib from heel, to heel around the shank and forepart.

Figure 9 represents the same innersole blank after it has been subjected to'the second outside channeling and turning operation to provide a'reinforcing member for the first-formed rib.

Figure 10 represents the blank after it has been split both at the shank and at, the toe end. Figure 11 represents a section on the line -11-11 of Figure 10.

innersole blank of suitablevmaterial which has been subjected to an outer channeling operation to form and turn up a rib 20 which extends from the dottedline aa at the heel end of the shoe along the shank and forepart ofthe innersole back to the said dotted line, so that there is thereby provided a continuous rib to which the welt and the upper may be stitched. The forepart of the innersole is now subjected to an inner chan-' 'neling operation by which there is provided an inside channel 21 and a rib 22 which extends from what might be called the front end of the shank around the forepart, the two ribs 22 and 20 being spaced at their bases far. enough to afford ample-betweensubstance through which the needle may pass in stitching the welt and the upper to the innersole. The innersole is now split 3 from the heel end forwardly to the dotted preferably adapted for womfirstto Figures 1150 7 inclusive,

' the rib 22 terminates, the line of the split being indicated at -0 in Figure 7 The feather along the shank on both sides thereof is thus split and it then coated with cement and upturned backwardly or inwardly from the edge so as to be cemented to the upturned rib 20, the reinforcing rib thus formed by the splitting and turning operation being indicated at 23. IVith the innersole thus formed, itwill be seen that, during the welting operation wherein the welt and the upper are stitched to the innersole, the machine guide will engage the base of the rib during the stitching operation along the shank and will enter the channel 21 and engage the base of the rib 22 during the operation on I the forepart. The guidewill enter and leave the channel with out difficulty. The formation of the reinforcing ribs 23 alfords a thickness of be tween-substance in the innersole approxi- .mating that at the forepart due to the formation of the inner channel and the rib 22 which results therefrom. An innersole as thus described is more especiallyapplicable for mens footwear, although it will be seen that it may be utilized in making womens shoes as well. I

In Figures 8 to 14, I have illustrated another embodiment of the invention which lends itself more especially to the forma' tion of womens footwear. In this case, the innersole isjfirst channeled along its outer edge to provide an upstanding rib 3O (turned inwardly or backwardly from the edge) whichuentends along the shank and the forepart continuously from heel to heel,-that is, from the dotted. line d d along the shank and around the ferepart and back to the dotted line. The feather of the inner sole may then be coated with cc ment, and the innersole is again channeled onthe outside to form a second upstanding rib 31 which is cemented. to the rib 30. If desired, the second channel maybe cut, and the rib then coated with cement and turned inwardly or baclnvardly and compressed against the rib so as to adhere thereto throughout its entire length. The innersole is then split from the heel. end to the forward end of the shank as indicated by the dotted line c-e, the plane of the split being coincident with the base of the rib 31, as shownin Figure 4-. If desired, the toe end ofthe innersole may be split towardsthc heel'to approximately the line f-fat the ball of the foot so as to afford two integrally-connected members at-the, toe end of the innersole as well as the two integrallyc-onnected members at the shank.

I11 the case of both innersoles, as'herein described, it will be I seen-that the innersole is split at the shank to afford two shank reinforcing rib.

ward ends at approximately the ball of the shank but which are free from each other along the shank; and further that in each case there is a rib which extends continuously along both sides of the shank and H case of one innersole, the reinforcing rib.

member is formed by splittingthe blank on. a plane below the base of the first or inner rib member {and then upturning, the'split edge,and, in the second case, by an outside channeling operation which is performed before theshank of the innersole is split. In one of the innersoles there is an in'slde channel, as in Figure 3, in the forepart of the innersole; whereas, inthe case, of the other innersole, the second outside channeling operation provldes a relnforcmgrib which is continuous from heelto heel and extends along the shank and around the forepart. 5

It-is evident that the precise order of the steps taken in forming the innersole may be varied and that a definite sequence ofoperations isnot necessary; For example,the re-i inforc-ing ribs at the shank of the innersole first herein describedare formed by and si multaneously with the splitting operation, in which event the operation of turning the ribs upwardly and backwardly or inward lv is preferably performed subsequently;

whereas, in the second described innersole,

the splitting of the shank follows the channeling operation by'which the outer reinturning operation may followthe channeling and the splittlng operatlons or it may occur between them, as most convenient.

\Vhat I claim is u I 1. An 1111161'5016COIIlPllSlDg a blank havmg an lntegral feather, a rib upturned from the body of theblank and extending continforcing rib is formed. In this case, the rib- T of the i1111ElS0l6,tl18 feather and the upturned ribs together being in thickness substantially equal to the body of the blank, and said innersole being split at its shank portion on the 2. An innersole comprising a blank hav-' ing an integral feather, a rib upturnedfrom the body' of the blank and extending con-.. unembers which are connected at their fortinucusly along both sides of the shank and plane of the base ofisaid the fol'epart and turned up and back 01' insaid innersole being split at its shank por- Ward from the edge, and a reinforcing'rib tion and from the toe end substantially to also upturned from the body of the blank the ball lineon the plane of the base of said 10 outside the first-mentioned rib 0n the shank reinforcing rib.

5 portion of the innersole, the feather and the In testimony whereof I have affixed my upturned ribs together being in thickness signature.

substantially equal to the body of the blank, JOHN F. TEEHAN.
