Abstract
Abstract Apparatus having a pallet for supporting a workpiece for movement relative to a tool. The pallet is removably mounted on moving means operative to move the workpiece on the pallet relative to the tool. The moving means comprise a movable support for the pallet, motive means, and a resilient, arcuate interconnection between the support and the motive means. The pallet has means for securing the workpiece against movement relative to the pallet and an aperture for providing tool access to portions of the workpiece where the tool operates on the workpiece.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
In a sewing machine having a reciprocating needle and a needle reciprocating mechanism, a holding tool for supporting the workpiece comprising: A. an apertured nipple which is mounted for reciprocating movement into supporting engagement with the workpiece, the nipple aperture being substantially axially aligned with the needle during workpiece engagement; and B. reciprocating nipple drive means operatively connected to said needle reciprocating mechanism to cause the nipple member to intermittently engage the workpiece in timed relation to needle penetration of the workpiece.
Claim 2
Dependent Claim
82 words
In a sewing machine having a reciprocating needle and a needle reciprocating mechanism, a holding tool for supporting the workpiece comprising: A. an apertured nipple which is mounted for reciprocating movement into supporting engagement with the workpiece, the nipple aperture being substantially axially aligned with the needle during workpiece engagement; and B. reciprocating nipple drive means operatively connected to said needle reciprocating mechanism to cause the nipple member to intermittently engage the workpiece in timed relation to needle penetration of the workpiece.
Claim 3
Dependent Claim
48 words
In a sewing machine having a reciprocating needle, a holding tool for supporting the workpiece as described in claim 1 wherein the apertured nipple is mounted on a support arm, said arm being pivotally mounted to provide reciprocating movement of the nipple into supporting engagement with the workpiece.
Claim 4
Dependent Claim
68 words
In a sewing machine having a reciprocating needle, a holding tool for supporting the workpiece as described in claim 2 wherein the reciprocating drive means comprises: A. an eccentrically mounted cam member operatively connected to the pivoting support arm; and B. means connected to the eccentric for causing rotation thereof in a manner that provides for supporting engagement of the holding tool during needle penetration of the workpiece.
