Abstract

Abstract In accordance with the invention a coupling means is provided for a circuit conveyor of the type comprising a pulling chain having ratchets presenting fingers, a suspended track below the chain for bogies having forward and rearward drive units rolling on said track, coupling components having movable members mounted on the pulling chain, said bogies having fixedly mounted coupling elements cooperating with said coupling components, said coupling components on said pulling chain including a housing supporting a ratchet finger and a latch lever pivotally mounted on horizontal axes for pivotal movement in opposite directions, said latch lever normally retaining said ratchet finger in position for engagement, each rearward drive unit having a running path for cooperation with said ratchet finger to move said ratchet finger upwardly, one said bogy having a roller with a cap and said cap supporting a roller and having a forward curved portion defining said running path and a rearward vertical abutment surface, and a rearward roller having a cap having vertical forward and rearward surfaces, said ratchet lever serving also as a latch lever and presenting a nose adapted to stop said ratchet finger in vertical position above the axis of rotation thereof and when in raised position release said ratchet lever, and the combination of said latch lever and said ratchet lever and finger further including a drop lever pivotally supported in said housing having a lower end adapted to cooperate with a roller cap and an abutment in said housing for engagement by an end of said drop lever.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 247 words
Coupling means for circuit conveyor of the type comprising a pulling chain having ratchets presenting fingers, a suspended track below said chain for bogies having forward and rearward drive units rolling on said track, coupling components having movable members mounted on said pulling chain, said bogies having fixedly mounted coupling elements cooperating with said coupling components, said coupling components on said pulling chain including a housing supporting a ratchet finger and a latch lever pivotally mounted on horizontal axes for pivotal movement in opposite directions, said latch lever normally retaining said ratchet finger in position for engagement, each rearward drive unit having a running path for cooperation with said ratchet finger to move said ratchet finger upwardly, one said bogy having a roller with a cap and said cap supporting a roller and having a forward curved portion defining said running path and a rearward vertical abutment surface, and a rearward roller having a cap having vertical forward and rearward surfaces, said ratchet lever serving also as a latch lever and presenting a nose adapted to stop said ratchet finger in vertical position above the axis of rotation thereof and when in raised position releases said ratchet lever, and the combination of said latch lever and said ratchet lever and finger further including a drop lever pivotally supported in said housing having a lower end adapted to cooperate with a roller cap and an abutment in said housing for engagement by an end of said drop lever.
Claim 2
Dependent Claim 247 words
Coupling means for circuit conveyor of the type comprising a pulling chain having ratchets presenting fingers, a suspended track below said chain for bogies having forward and rearward drive units rolling on said track, coupling components having movable members mounted on said pulling chain, said bogies having fixedly mounted coupling elements cooperating with said coupling components, said coupling components on said pulling chain including a housing supporting a ratchet finger and a latch lever pivotally mounted on horizontal axes for pivotal movement in opposite directions, said latch lever normally retaining said ratchet finger in position for engagement, each rearward drive unit having a running path for cooperation with said ratchet finger to move said ratchet finger upwardly, one said bogy having a roller with a cap and said cap supporting a roller and having a forward curved portion defining said running path and a rearward vertical abutment surface, and a rearward roller having a cap having vertical forward and rearward surfaces, said ratchet lever serving also as a latch lever and presenting a nose adapted to stop said ratchet finger in vertical position above the axis of rotation thereof and when in raised position releases said ratchet lever, and the combination of said latch lever and said ratchet lever and finger further including a drop lever pivotally supported in said housing having a lower end adapted to cooperate with a roller cap and an abutment in said housing for engagement by an end of said drop lever.
Claim 3
Dependent Claim 26 words
Coupling means for circuit conveyor in accordance with claim 1, where said drop lever includes a pin which cooperates with the end of the latch lever.
Claim 4
Dependent Claim 24 words
Coupling means in accordance with claim 2, where the arm of the latch lever defines one end thereof and is provided with a counterweight.
Claim 5
Dependent Claim 19 words
Coupling means in accordance with claim 1, where said drop lever is subject solely to the force of gravity.
Claim 6
Dependent Claim 21 words
Coupling means in accordance with claim 4, comprising an additional drop lever corresponding in shape to that of the ratchet finger.
