<p>1,215,726. Conveyer apparatus for electro-plating. MIF INDUSTRIES Inc. Feb.14, 1968 [Dec. 22, 1967], No.7293/68. Heading C7B. [Also in Division B8] Containers 32 are dipped into a plating bath 42 after being picked up by members 116 suspended from an arm 60 pivotably mounted at 62 on a carriage 64 mounted on rails 38 and 40 by the action of an endless chain 54, the arm 60 having a cam follower 82 which co-operates with cam sections 44. A latch 122 on the carriage 64 co-operates with a lug 128 on the arm 60 to maintain the load in a raised position so as to avoid provision of cam sections 44 at unnecessary parts of the conveyer track. At the loading end of each cam section 44, a member 132 of the latch 122 is adapted to be engaged by a fixed cam plate 134 so as to release the arm 60. The members 116 may be adapted to engage recesses in the rim of the container 32, or may be replaced by a rack (108) Fig. 6 (not shown). The tension of the chain 54 is adjusted by movement of a sub frame 135, Fig. carrying two guide sprockets 52. The frame 135 carries continuation sections 38a, 40a, Figs.24, 26, of the rails 30, 40. Slotted-in rail portions 152, 154, maintain track continuity for the running wheels 70, 70, 77, Figs. 3 and 4 of the carriage 64. Adjustment of the sub frame 135 is effected by rotation of a threaded draw-member (158) Fig.25, (not shown).</p> |
