Claims
- 1. An improved coupling assembly for use in combination with a conveyor means to form a machine that carries a hollow workpiece between a workpiece loading station and a workpiece unloading station and then returns to the former which machine further includes conveyor means movably mounted relative to the base of said machine for supporting at least one such coupling for repeated movement along respective first and second paths to and away from said respective stations for loading and unloading and wherein said improved coupling comprises
- (a) a carrier that is a part of said conveyor means;
- (b) a support member having an upper stem portion and a lower portion, said upper portion being mounted on said carrier to revolve but not reciprocate relative to said carrier, said lower portion being cup-shaped, the cup being defined by an annular wall surrounding a chamber and an end wall connecting said stem portion to said annular wall and having an open end on the bottom of said cup opposite said end wall;
- (c) a follower slidably supported in said stem portion and having the lower end of said follower within said chamber, said follower being movable axially toward and away from said open end;
- (d) detent means comprising a lever means pivotally mounted on said lower portion with one lever arm engageable by said follower and the end of the other said lever arm disposed to be radially movable within said chamber, respectively, away from and toward the central portion of said chamber responsive to axial movement of said follower to respectively disengage and engage such workpiece;
- (e) an ejector means movably mounted on said lower end of said follower; and
- (f) means to resiliently bias said ejector means toward said cup open end.
- 2. An improved coupling for use in combination with a conveyor means according to claim 1, wherein said ejector means includes a radially extending member reciprocably mounted on said follower lower end of a size sufficient to engage the workpiece, and said means to bias is a spring.
