Abstract
Abstract This invention involves a pallet for use in automatic stitching machines which insures proper registration of a workpiece with respect to the stitching instruments and maintenance of such registration during machine operation. Basically, the pallet is constructed of two outer plates hinged together to form a sandwich type arrangement having openings therein to allow for access of the stitching instruments to the workpiece. These openings are generally identical and are accurately located with respect to the stitching instruments. In the interior of the pallet means are provided for removably securing the workpiece in accurate registration with the stitching instruments. The access openings may be designed to receive overlay or overlapping portions of a composite workpiece and additional outer or interior plates may be provided to accommodate a wide variety of workpieces. The pallet is removably secured to the supporting carriage of the automatic stitching machine in a position which is fixed in relation to the stitching head.

Claim 2
Dependent Claim
149 words
In a stitching machine which utilizes an automatically controlled carriage for moving the workpiece in relation to the stitching instruments, a device for registering and securing the workpiece in a fixed position on the carriage with respect to the instruments, comprising: A. a base plate having a cavity therein to receive the workpiece and limit the movement thereof said cavity conforming to the shape of the workpiece and being registered in a fixed position with respect to the instruments, said base plate further having openings therein to allow access to the workpiece for the stitching instruments; B. a cover plate removably secured to the base plate to enclose the workpiece, said cover plate having opening therein to allow access to the workpiece for the stitching instruments, said openings being in fixed registration with said instruments; and C. means for removably securing the base plate to the automatically controlled carriage.
Claim 3
Dependent Claim
76 words
In a stitching machine which utilizes an automatically controlled carriage for moving a workpiece in relation to the stitching instruments, a device for registering and securing a workpiece in a fixed position on the carriage with respect to the instruments, as described in claim 1 wherein the cover plate is secured to the base plate by means of hinges which allow the cover plate to pivot away from the base plate to expose the cavity therein.
Claim 4
Dependent Claim
152 words
In a stitching machine which utilizes an automatically controlled carriage for moving the workpiece in relation to the stitching instruments, a device for registering and securing the various parts of a composite workpiece in a fixed position on the carriage with respect to the instruments, said composite workpiece including base and overlay portions, comprising: A. a base plate having a cavity therein to receive the base of the workpiece, said cavity being registered in a fixed position with respect to the instruments, said base plate further having openings therein to allow access to the workpiece; B. a cover plate removably secured to the base plate to enclose the base cavity, said cover plate having openings therein to allow for access to the workpiece and for providing a cavity to receive the overlays in fixed registration with the instruments; and C. means for removably securing the base plate to the automatically controlled carriage.
Claim 5
Dependent Claim
152 words
In a stitching machine which utilizes an automatically controlled carriage for moving the workpiece in relation to the stitching instruments, a device for registering and securing the various parts of a composite workpiece in a fixed position on the carriage with respect to the instruments, said composite workpiece including base and overlay portions, comprising: A. a base plate having a cavity therein to receive the base of the workpiece, said cavity being registered in a fixed position with respect to the instruments, said base plate further having openings therein to allow access to the workpiece; B. a cover plate removably secured to the base plate to enclose the base cavity, said cover plate having openings therein to allow for access to the workpiece and for providing a cavity to receive the overlays in fixed registration with the instruments; and C. means for removably securing the base plate to the automatically controlled carriage.
Claim 6
Dependent Claim
85 words
In a stitching machine which utilizes an automatically controlled carriage for moving a workpiece in relation to the stitching instruments, a device for registering and securing a composite workpiece in a fixed position on the carriage with respect to the instruments, said composite workpiece including base and overlay portions, as described in claim 3 wherein the cover plate is secured to the base plate by means of hinges which allow the cover plate to pivot away from the base plate to expose the base cavity.
Claim 7
Dependent Claim
137 words
In a stitching machine which utilizes an automatically controlled carriage for moving a workpiece in relation to the stitching instruments, a device for registering and securing a composite workpiece in a fixed position on the carriage with respect to the instruments, said composite workpiece including base and overlay portions, as described in claim 3 wherein the base plate comprises: A. a frame member having an opening therein: B. a bottom plate secured to the frame member and providing a bottom enclosure to the frame member opening; said bottom plate having openings therein to allow access to the workpiece; and C. a template which is removably secured in full registration within the frame member opening, said template being cut out to form a cavity within the base plate which conforms to the size and shape of the workpiece.
Claim 8
Dependent Claim
