Abstract
Abstract An overhead conveyor comprising an endless draw member travelling along a closed stretch and containing regularly spaced claws in which a carrier hook such as a coat-hanger can be suspended, each claw being capable of closing and opening for carrying or dropping a hook. The conveyor is further provided with throw-off stations, positioned along its stretch, a number of stations comprising a catching rail movable between an active and in inoperative position. In its active position the rail can receive a hook, dropped by an open claw. In its inoperative position the travelling claws with a hook are able to pass through the concerning throw-off station.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
207 words
An overhead conveyer comprising an endless draw member traveling along a stretch, said member being provided with pick up claws mounted at regular distances from each other, which claws can be selectively adjusted between closed and open positions for transporting or dropping respectively a carrier hook suspended in a claw in transverse position relative to the direction of travel of the conveyer, the carrier hook being of the type in which one side is closed and the other side being open and having a beak, said conveyer further comprising a number of throw off stations each being provided with means for opening a passing claw, each of said stations on the side of the conveyer toward which the beak of the hook is facing will further comprise a stationary rail having a tongue reaching into the path of travel of the carrier hook, and each of said stations on the opposite side comprising an adjustable rail having a tongue which is selectively displaceable between a catching and an inactive position, the catching position being when the free end of the tongue is lying within the path of the carrier hook, said inactive position being when the tongue is lying completely outside the path of the carrier hook.
Claim 2
Dependent Claim
207 words
An overhead conveyer comprising an endless draw member traveling along a stretch, said member being provided with pick up claws mounted at regular distances from each other, which claws can be selectively adjusted between closed and open positions for transporting or dropping respectively a carrier hook suspended in a claw in transverse position relative to the direction of travel of the conveyer, the carrier hook being of the type in which one side is closed and the other side being open and having a beak, said conveyer further comprising a number of throw off stations each being provided with means for opening a passing claw, each of said stations on the side of the conveyer toward which the beak of the hook is facing will further comprise a stationary rail having a tongue reaching into the path of travel of the carrier hook, and each of said stations on the opposite side comprising an adjustable rail having a tongue which is selectively displaceable between a catching and an inactive position, the catching position being when the free end of the tongue is lying within the path of the carrier hook, said inactive position being when the tongue is lying completely outside the path of the carrier hook.
Claim 3
Dependent Claim
40 words
A conveyer according to claim 1 characterized in that the displacement of the tongue at the free end of each movable catching rail (8) from its catching position to its discharge position has a sideward component and an upward component.
Claim 4
Dependent Claim
71 words
A conveyer according to claim 1 or 2 characterized in that each movable catching rail (8) comprises a fixed bar portion (20) and a movable bar portion (21), both portions being provided with a continuous flexible plastic profile (24) which functions as a hinge between the two bar portions spaced from each other, in which the movable bar portion constitutes the tongue (9) at the free end of the catching rail.
Claim 5
Dependent Claim
72 words
A conveyer according to claim 3 characterized in that the tongue (9) at the free end of each movable catching rail (8) is mounted at an end of two braces (25) the other ends of which are connected to a common arm (26) rotatable around a shaft (27) having an axis (D) which cuts the pivotal portion of the catching rail under an angle with a vertical (E) to the catching rail.
Claim 6
Dependent Claim
45 words
A conveyer according to claim 2 characterized in that the tongue (9) at the free end of each movable catching rail (8) is mounted on a swivelling parallelogram-linkage (31) such that the tongue (9) of said rail is capable of being displaced horizontally and vertically.
