Claim 4
Dependent Claim
55 words
A machine as set forth in claim 1 wherein the means for tensioning and positioning the upper comprises a toe gripper and side grippers, power means for operating the grippers to tension the upper over its last and manually operable means for controlling the action of said grippers to position the upper on the last.
Claim 5
Dependent Claim
86 words
A machine as set forth in claim 1 wherein the means for clamping the tensioned and positioned upper to its last comprise a toe band and a heel band and wherein the means for holding the shoe on the carrier comprises a toe pad, and wherein means are provided at the upper tensioning and positioning station for moving the toe band and the heel band to operative positions after the upper has been tensioned and positioned and for thereafter moving the toe pad to operative position.
Claim 6
Dependent Claim
45 words
A machine as set forth in claim 4 wherein means are provided on the carrier for holding said toe band, heel band and toe pad in operative positions during movement of the carrier and during the action of the lasting instrumentalities at said other stations.
Claim 7
Dependent Claim
77 words
A machine as set forth in claim 1 wherein the means for clamping the tensioned and positioned upper to its last comprises a toe band and the means for holding the shoe on the carrier comprise a toe pad and wherein means are provided at the upper tensioning and positioning station for moving the toe band to operative position after the upper has been tensioned and positioned and for thereafter moving the toe pad to operative position.
Claim 8
Dependent Claim
77 words
A machine as set forth in claim 6 wherein the toe band is mounted on the carrier for movements lengthwise and heightwise of the shoe thereon and wherein the means for operating the toe band include power operated members at the upper tensioning and locating station for effecting said lengthwise and heightwise movements of the toe band to caUse it to wipe the tensioned upper heightwise of the last and to clamp the upper to the last.
Claim 9
Dependent Claim
31 words
A machine as set forth in claim 1 wherein means are provided for engaging the toe end of the last to locate the shoe in a lengthwise direction on the carrier.
Claim 10

Claim 11
Dependent Claim
77 words
A machine as set forth in claim 1 wherein the means for clamping the tensioned and positioned upper to the last comprise a heel band and the means for holding the shoe on the carrier comprises a toe pad and wherein means are provided at the upper tensioning and positioning station for moving the heel band to operative position after the upper has been tensioned and positioned and for thereafter moving the toe pad to operative position.
Claim 12
Dependent Claim
57 words
A machine as set forth in claim 10 wherein the heel band is mounted on the carrier for arcuate movement and wherein means are provided at the upper tensioning and positioning station for effecting such arcuate movement of the heel band to orient the heel band relatively to the bottom of the heel end of a shoe.
Claim 13
Dependent Claim
50 words
A machine as set forth in claim 11 wherein said means for effecting arcuate movement of the heel band comprises power operated means together with means for controlling the action of said power operated means including a sensing member for engaging the heel end of the bottom of the shoe.
Claim 14
Dependent Claim
136 words
