7 Claims.

This invention relates to machines for operating on shoes and is herein illustrated in itsapplication to machines for assembling shoe upper parts on their lasts preparatory to the pullingover and lasting operations. An embodiment o1 the invention is herein vshown as applied .to `a machine of the type disclosed, for example, in United States Letters Patent No. 1,356,510, granted October 26, 1929, onan application of Hannah Ashton, executrix of the will of Orrell Ashton.

Machines of the above type are provided with means for fastening the lasting margin yof the upper at the extremity ofthe heel portionof .the shoe to an insole on the last bottom. Usually, the upper is provided with a molded counterand the fastenings securing the lasting margin of the lining also secure the flange of the counter to the insole. For positioning the shoe relatively to the operating instrumentalities of the machine ,and bringing the side portions of the upperand the counter in against the last, the machine .illustra'ted in the Ashton patent is provided with side presser members which engage oppositesides of the upper at points adjacent to the lasting margin.

It sometimes happens that the counter is posi- -tioneda little high on the last. In orderto .correct this condition, the side pressing meansherein illustrated, in accordance with va feature of the invention, is constructed and arranged to apply pressure heightwise of the last to a molded counter misplaced heightwise thereof on the last, thereby to bring the counter into correct heightwise position with its flange seated .against vthe margin of an insole on the last bottom, .said pressing means after so positioning the counter acting to apply pressure widthwise of the last to the heel portion of the upper. The illustrated side presser members have means extending inwardly over the bottom of the last for engagement with the overlasting margin of the upper. The illustrated inwardly extending members are inclined upwardly over the last bottom adjacent to the corners and thewings of the counter and, as the side presser members swing inwardly toward the sides of the upper, their inwardly eX- tending members, by reason of their upward inclination, exert a pressure against the overlasting margin of the upper heightwise of the last. It will be understood that this heightwise pressure will lseat the flange of the counter firmly against the insole, if the counter is slightly misplaced heightwise of the last. It will also be understood that as the side presser members act on the flange of the counter to position the counter heightwise of the last, the counter will be free for such movementsince the side presser members do not apply pressure to the counter WidthvWise of the last until after the counter has been brought into correct heightwise position with its ange seated against the margin yof the insole.

The invention will now be described with -reference to the accompanying drawings and lpointed out in the appended claims.

In the drawings,

Fig. 1 is a perspective view illustrating the side presser members together with their operating mechanism;

Fig. 2 is a plan view illustrating the side presser members in operation on ashoe in the machine; and

Fig. 3 is a section on the line Ill-III of Fig. 2.

Referring to Fig. 1, the illustrated mechanism for operating the side presser members is substantially the same in its construction and'operation as the side presser operating mechanismto extend verticallydownwardlyfrom vthe front .of the machine head. The'bracket II] has bear- .ings in which are mounted vertical shafts I2 to the upper ends of whichrare secured carrier arms I4 on which are swiveled the side presser membersl. The carrier arms I4 are swungtoward each other to'advance the side presser members generally widthwise of-a shoe in the machine by torsion springs I8 surrounding the shafts I2. The operation of the carrier'arms by said springs is controlled by a hook 2E) whichacts against la roll 22 at theend of the horizontal larm of a bellcrank lever 24 the vertical arm of which presses against two arms 26 secured to the lower ends of the shafts I2 and arranged toextendinwardly therefrom. The hook 20 moves downwardly after the shoe has been brought into position to be operated upon and during such downward movement of the hook the bell-cranklever .24 is released for movementv in a counterclockwise .direction, as seen in Fig. 1, thus permitting the torsion springs I8 to swing the carrier arms I4 toward each other thereby operating the side presser member I6.

Referring to Figs. 2 and 3, the side presser members are generally U-shaped, as seen in plan View, and are swiveled on headed pins 28 in the front ends of the carrier arms Id. As in the machine illustrated in the Ashton patent, the side presser members I6 are held properly oriented for operation on a shoe in the machine by spring-pressed pins 3G mounted in the carrier arms I4 and arranged to engage shoulders 32 provided in the presser members. Referring to Fig. 3, the illustrated side presser members have upwardly and inwardly extending portions 34 which act against the opposite side portions of an upper, for example, the upper 36 mounted on the last 38. The illustrated side presser members have end portions 40 which extend inwardly over the last bottom, the bottom faces of said end portions extending inwardly with a slight upward inclination so as to enable them to exert a downward pressure or cam action on the lasting margin of the upper and the ange of a molded counter 42 positioned therein. Thus it will be seen that the side presser members, as they move widthwise of the last into engagement with the upper, apply pressure to the side portions of the upper widthwise of the last while simultaneously the end portions of said presser members apply pressure to the lasting margin of the upper and the flange of the counter heightwise of the last to seat the flange of the counter rmly against the margin of an insole 44 on the last bottom. It will be understood that in the event that the counter is misplaced heightwise of the last with the fiange of the counter spaced from the margin of the insole instead of being seated against said margin, the end portions di) of the side presser members will exert a downward pressure against the counter as the side presser members move inwardly, and by the time said presser members have come into position to apply pressure widthwise of the last to the side portions of the upper, the counter will have been brought into correct position heightwise of the last. As seen in Fig. 2, the end portions 40 of the side presser members are arranged to act on the flange of the counter at points adjacent to the corners and the wings of the counter thereby assuring a correct longitudinal alinement of the counter on the last.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a machine for assembling an upper and a molded counter on a last preliminary to lasting, the combination with means for4 supporting the last in a predetermined position heightwise thereof, of a presser member operable to apply pressure heightwise of the last to a molded counter misplaced heightwise thereof on the last thereby to bring the counter into correct heightwise position with its ange seated against the margin of an insole on the last bottom, said presser member, after so positioning the counter, acting to apply pressure widthwise of the last to the heel portion of the upper.

2. In a machine for assembling an upper and a molded counter on a last preliminary to lasting, a presser member operable by movement widthwise and not heightwise of the shoe to apply heightwise pressure to a molded counter misplaced heightwise of the last thereby to seat the flange of the counter against an insole on the last bottom, said presser member, after so positioning the counter, acting to apply pressure widthwise of the last to the heel portion of the upper.

3. In a machine for assembling an upper and a molded counter on a last preliminary to lasting, a sidel presser member movable widthwise of the last rst to apply pressure to the lasting margin of the upper and the ange of the counter heightwise of the last and thereafter to apply pressure to a side portion of the upper widthwise of the last.

4. In a machine for assembling an upper and a molded counter on a last preliminary to lasting, a side presser member movable widthwise of the last first to exert a cam action on the lasting margin of the upper and the flange of the counter thereby to position the counter heightwise of the last and thereafter to apply pressure to a side portion of the upper widthwise of the last.

5. In a machine for assembling an upper and a molded counter on a last preliminary to lasting, a side presser member movable generally widthwise of the last to apply pressure to a side portion of the upper, and a member extending inwardly and upwardly over the last bottom from said side presser members and operating during movement of the side presser member toward the last to apply pressure to the lasting margin of the upper and the flange of the counter heightwise of the last.

6. In a machine for assembling an upper and a molded counter on a last preliminary to lasting, a pair of side presser members movable generally widthwise of the last to apply pressure to opposite side portions of the upper, said presser members having members extending inwardly at an upward inclination over the bottom of the last adjacent to the corners and the wings of the counter and operating during movement of the presser members toward the last to apply pressure to the lasting margin of the upper and flange of the counter heightwise of the last.

7. In a machine for assembling an upper and a molded counter on a last preliminary to lasting, a pair of side presser members each comu prising an arm mounted for movement generally widthwise of the last, a presser member fulcrumed on said arm on an axis extending heightwise of the last, said presser member having a pair of work-engaging members positioned at opposite sides of said fulcrum and characterized by end portions constructed and arranged to extend inwardly with an upward inclination over the ange of the counter and operable upon inward movement of the side presser members to press the counter downwardly and seat its flange against an insole on the last bottom.
