This invention relates to means for positloning lnsoleson thelr lasts durmg a portlon of the operations of shoe manufacture. An-

machines for performing those operations,

andof such a characterasto adapt itto be readily applied to the insole and last and removed therefrom.

To this and other'ends, the invention provides a novel insole-positioning device of a type which is portable with the last and insole,comprising, in its illustrated form, a sheetmetalclamping member adapted to be applied iover'the bottom face of the insole transversely of the forepart of the last and having thereon a pair of pins arranged to project through holes in the insole into corresponding holes in the bottom of the last in locations spaced widthwise of the forepart to attach the device to the last and to position the insole accurately in properlengthwiseylateral and angular relationto the last. The device herein shown 1s thus adapted for use wherethe proper relation betweenthe insole "andthe last is predetermined by the useofholes formedin the last and in the insole at the forep'art in such locations as to align with one another when the insole is in proper position, in accordance with a method disclosed --in Letters-Patent No. 1,674,060, granted "upon my application on June 19, 1928, Preferably, :in order to retain the-device in operative position, theclamping memher is formed of-spri'ng metal so shaped as'to adapt it to'be sprung'into clamping position in applying the device to the lasti'and insole, and-the pins are so arranged that'bythe resiliency of this member in itsclampingpos1- tion'they are cramped in the holes in'thelast.

The invention will now be more particularly described by reference to the accompanying drawings andth'ereafter pointed out in the claims.

In'the drawings,

'50 Fig. l is a'perspective View of a last with an insole positioned thereon by the use of means constructed in accordance with the thecinsole-posipositioning the last and its shoe materials in proper relation to a etoe-lasting .or other machine in further accordance with the method disclosed in the Letters Patent above men tioned. fine of the holes in theinsole, was shownat in Fig. 1 is located near the toe end of the insole and in position to align with a corresponding hole (not shown) in the bot.

tom of the last, while the other two holes in the insole, indicated at 12 in Fig.2, arespaced apart widthwise of the last at the rear of the hole 170 in position to align with corresponding holes 14 formed in metal bushings 16 inthebottom of the last. The device herein shown for positioningthe insole ongthe last is so @formed as "to utilize the rear pairs of holes 12and 14 in the insole and-in the last,

and ftoathatend comprisesa clampingmemher 18 of such dimensionsas to adapt itto extend lengthwise in transverseor widthwise relation to the forepart ofthe insole, the device being provided on one side thereof near its opposite endswithpins 20 which, in the construction illustrated, are secured to the member 18by riveting them to this member and are so arranged as to adapt them to project through :the holes 12 inthe insole into the holes'ld in the last. The clamping member 18ois formed preferably of sheet metal, such as steel, which is resilient and of such contour that themember presents initially a concave face toward theibottom face of the insole. and is adapted to be sprung ;into aposition in which it lies throughout its length :in 811bstantially contiguous-relation to said face. --In the construction shown the clamping member is of greater length than width, its length operation in the manner disclosed in the Let tersPatentmentioned. Since the clamping being such as to adapt it to extend over a large portion of the width of the insole with the pins 20 spaced far enough apart for effective actionin holding the'insole in proper angula'r'relation to the last, while its width is limited as far as is consistent with proper strength of the member in order to facilitate the springing of the memberinto clamping position. All that is necessary in applying the device to the work isto present it with the pins 20 substantially in position to enter the holes in the insole and'the last, and then to press the device down to force the pins into the holes and to spring the member 18 into a position close to the bottom face of the insole, the springing of the member serving to bring the pins into substantially parallel relat-ion to the'holes so that they will enter the holes readily. It will be evident that the member 18 will then act by its resiliency to cramp the pins 20 in theholes 14 in the last, so that the device 'will be held securely in place. When it is desired to remove the device, this maybe conveniently done by inserting a suitable tool between the insole and the the work when the insole is assembled with thelast, andin its illustrated use it is intended toremain'in operative position during the pulling-over and side-lasting operations on the shoe, after which it will be removed to permitthe holes in the insole and last to be used in positioning the shoe for the toe-l asting member 18 formed of thin sheet metal which lies close to the bottom face of the insole and :since there is nothing, on the outer V side or face o'fthis member which projects presentation of t toany substantial extent heightwise of .the last; itzwill be evident thatthe device is of suchcons'truction as not to interfere with the he shoe to a pulling-over machine of the usual typei There is likewise nothing in the construction ofthe device and its relation ,to the shoe to interfere with the operation of" the sidelasting machine, since in addition to the above-mentioned characteristicsthe dCVl'CG IS'lOCalZQCl at a wldeportion of the insole, 'as'distinguished from the comparatively narrow shank, and'terminates far enough-from the side'edges of the insole to allow ample room for the overlaying and fastenin'gof the upper. In addition to the advantages above mentionedgit isto be noted that the device de- 'scribedpositi ons the insole in properlengthuse of a molded insole. in Fig. 1, the heel end portion of the insole is the holes in the insole and last( wise, lateral and angular relation to the last, that it is of simple construction and inexpensive to manufacture, and that the same device may be used interchangeably in making shoes of a number of different sizes Furthermore, the arrangement whereby the clamping member extends widthwise of the forepart to locations near the side edges of the insolecontributes efiectively to the hold. ing of the side portions of the insole close to the bottom face of the last. i c

The drawings illustrate an insole which has been previously molded to conform substantially to the contour of the bottom of the last, but it will be understood that the invention does not depend for utility upon the As shown, moreover,

fastened to the last by the use of a tack t to hold itfrom shifting laterallyafter the insole as a whole has been positioned by the use of the device hereinbefore described. While the use of such a tack may be desirable in op erating upon'some kinds of work,'it' will be recognized that frequently conditions will be such that it may be dispensed with. "It is further to be understood that the invention, in its more general aspects,is not limited to insole-positioning means provided with two pins to enter holes in'the insole and last, nor 7 to an arrangement of the pins andholes in ii the particular relation to the last-herein disclosed. Moreover, it will be recognized that the utility of the invention is not dependent upon the use of a-device having pins. or projections of the particular form and construc- '1 tion herein illustrated, and inthev appendedclaims the term tpinstis accordingly'used in a general rather than a restrictive sense to define those portions of the device that enter Having described the invention, what I claim as new and desire to 'securefby Letters Patent of the United States is c 1.
