Indexing machine transfer mechanism

Claim 2

In combination with an indexing machine of the type wherein various mechanical operations are performed on articles at workstations about a worktable rotatable about a center, the improvement which comprises: a. a transfer means for picking up and placing the articles on the worktable; b. a support means mounted on the indexing machine and in operative engagement with a drive shaft below the worktable for operation within the periphery of the worktable and penetrating the plane of the worktable for reciprocating the transfer means; and c. a projection means mounted on the indexing machine in operative engagement with a drive shaft below the worktable for operation within the periphery of the worktable and penetrating the plane of the worktable within the periphery of the worktable for oscillating the transfer means between a first point beyond the periphery of the worktable and a second point within the periphery of the worktable, whereby the reciprocating action of the support means and the oscillating action of the projection means combine with the pickup action of the transfer means.

Claim 3

The improvement described in claim 1, wherein the support means comprises a drive shaft disposed perpendicularly to the worktable, a barrel cam mounted on the drive shaft, a center shaft mounted coaxially with the worktable, a cam follower fastened to the center shaft in operative relation with the barrel cam, fastened to the center shaft a tool plate, and a carrying means supported by the tool plate to hold the transfer means, whereby the rotation of the drive shaft reciprocates the transfer means.

Claim 4

The improvement described in claim 1, wherein the projection means comprises a drive shaft disposed perpendicularly to the worktable, a barrel cam mounted on the drive shaft, a rod mounted perpendicular to the worktable, a cam follower fastened to the rod in operative relation with the barrel cam, a collar mounted to the rod above the worktable, a lever in operative cooperation with the collar mounted on the rod, and a collar on the transfer means operatively cooperating with the lever whereby the rotation of the drive shaft oscillates the transfer means between a first point beyond the periphery of the worktable and a second point within the periphery of the worktable.

Claim 5

The improvement of claim 1, wherein the support means comprises a drive shaft disposed perpendicularly to the worktable, a first barrel cam mounted on the drive shaft, a center shaft mounted coaxially with the worktable, a cam follower fastened to the center shaft in operative relationship with the first barrel cam, a tool plate fastened to the center shaft above the worktable, and a carrying means supported by the tool plate to hold the transfer means for reciprocating the transfer means, and the projection means comprises a second barrel cam mounted on the drive shaft, a rod mounted perpendicularly to the worktable, a cam follower fastened to the rod in operative relation with the second cam, a collar mounted to the rod above the worktable, a stationary plate disposed between the collar mounted on the rod and the worktable, a bell crank lever pivotally supported by the stationary plate having a first arm operatively connected to the collar mounted on the rod, and a collar on the transfer means operatively connected to the second arm of the bell crank lever for oscillating the transfer means between a first point beyond the periphery of the worktable and a second point within the periphery of the worktable, whereby the rotation of the drive shaft reciprocates and oscillates the transfer means.

Claim 6

The improvement described in claim 1, wherein the support means comprises a drive shaft disposed parallel to the plane of the worktable, a cam mounted on the drive shaft, a center shaft mounted coaxially with the worktable, a cam follower joined to the center shaft in operative relation with the cam, fastened to the center shaft a tool plate, and a carrying means supported by the tool plate to hold the transfer means, whereby the rotation of the drive shaft reciprocates the transfer means.

Claim 7

The improvement described in claim 1, wherein the projection means comprises a drive shaft disposed parallel to the plane of the worktable, a cam mounted on the drive shaft, a rod mounted perpendicular to the worktable, a cam follower joined to the rod in operative relation with the cam, a collar mounted to the rod above the worktable, a lever in operative cooperation with the collar mounted on the rod, and a collar on the transfer means operatively cooperating with the lever whereby the rotation of the drive shaft oscillates the transfer means between a first point beyond the periphery of the worktable and a second point within the periphery of the worktable.

Claim 8

The improvement of claim 1, wherein the support means comprises a drive shaft disposed parallel to the plane of the worktable, a first cam mounted on the drive shaft, a center shaft mounted coaxially with the worktable, a cam follower joined to the center shaft in operative relation with the first cam, fastened to the center shaft a tool plate, and a carrying means supported by the tool plate to hold the transfer means for reciprocating the transfer means, and the projection means comprises a second cam mounted on the drive shaft, a rod mounted perpendicular to the worktable, a cam follower joined to the rod in operative relation with the second cam, a collar mounted to the rod above the worktable, a lever in operative cooperation with the collar mounted on the rod, and a collar on the transfer means operatively cooperating with the lever, whereby the rotation of the drive shaft reciprocates and oscillates the transfer means.
