Abstract
Abstract This conveyor intended for the transport of objects possibly mounted on supports comprises a succession of standard rectilinear transport elements, each controlled by a reduction drive motor and each including at least two pulleys; a transmission element such as a chain or a belt, the said transmission element being provided with gripping members designed to catch hold of the objects to be transported or their supports, the said transmission element being passed round the two said pulleys; guide rails for the transmission element; at least one supporting surface intended to bear the weight of the object and its support; and means of transfer able to unfasten the objects or their supports from a standard rectilinear transport element and to engage them with another standard rectilinear element of the conveyor.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
241 words
Conveyor and transfer system comprising a plurality of supports adapted to mount articles for conveyance therealong, each said support comprising a vertically depending rod having at its lower end a portion for suspending an article, a suspension portion fastened to said rod at its upper end, hook means fastened to said rod intermediate said ends, radially extending elements connected to said rod along the length thereof, a plurality of contiguously positioned identically-shaped conveyor elements disposed in a common horizontal plane, each said conveyor element including at least two end pulleys, stationary frame means rotatably mounting said end pulleys, endless motion transmitting means inter-connecting said pulleys, gripping means attached to said motion transmitting means adapted to engage said hook means for driving the latter, guide rails for said motion transmitting means, track means disposed on said guide rails and adapted to be engaged by said suspension portion for supporting said supports, stationary orientation elements mounted on said frame means and disposed between each of two of said contiguous conveyor elements, said orientation elements being adapted to cooperatively engage said radially extending elements duRing movement of the supports on at least one of said two contiguous conveyor elements to thereby rotate said support about its vertical axis to an extent disengaging said hook means from the gripping means on said motion transmitting means and to engage the hook means with the gripping means of a motion transmitting means of the successive conveyor element.
Claim 2
Dependent Claim
241 words
Conveyor and transfer system comprising a plurality of supports adapted to mount articles for conveyance therealong, each said support comprising a vertically depending rod having at its lower end a portion for suspending an article, a suspension portion fastened to said rod at its upper end, hook means fastened to said rod intermediate said ends, radially extending elements connected to said rod along the length thereof, a plurality of contiguously positioned identically-shaped conveyor elements disposed in a common horizontal plane, each said conveyor element including at least two end pulleys, stationary frame means rotatably mounting said end pulleys, endless motion transmitting means inter-connecting said pulleys, gripping means attached to said motion transmitting means adapted to engage said hook means for driving the latter, guide rails for said motion transmitting means, track means disposed on said guide rails and adapted to be engaged by said suspension portion for supporting said supports, stationary orientation elements mounted on said frame means and disposed between each of two of said contiguous conveyor elements, said orientation elements being adapted to cooperatively engage said radially extending elements duRing movement of the supports on at least one of said two contiguous conveyor elements to thereby rotate said support about its vertical axis to an extent disengaging said hook means from the gripping means on said motion transmitting means and to engage the hook means with the gripping means of a motion transmitting means of the successive conveyor element.
Claim 3
Dependent Claim
44 words
Conveyor and transfer system as claimed in claim 1, wherein said orientation elements comprise stops disposed along the path of the gripping means on the first of said two contiguous conveyor elements, and substantially upstream of the transfer point between said successive conveyor elements.
Claim 4
Dependent Claim
57 words
Conveyor and transfer system as claimed in claim 1, each said end pulley comprising a double-grooved pulley, a relay pulley disposed intermediate said end pulleys, a relay motion transmitting means inter-connecting and extending about said relay pulley and an end pulley of a successive conveyor element, and gripping means being provided on said relay motion transmitting means.
Claim 5
Dependent Claim
76 words
Conveyor and transfer system as claimed in claim 1, comprising an inclined conveyor element for effecting changes in the plane of article conveyance, an upper end pulley for said inclined conveyor element being disposed adjacent an end pulley of a conveyor element in an upper plane of article conveyance, and a lower end pulley for said inclined conveyor element being disposed adjacent an end pulley of a conveyor element in a lower plane of article conveyance.
Claim 6
Dependent Claim
49 words
Conveyor and transfer system as claimed in claim 4, including gripping means on a motion transmitting means for said inclined conveyor element, said suspension portion of said support including a ring portion adapted to engage said last-mentioned gripping means for effecting the change of plane in the article conveyance.
Claim 7
Dependent Claim
30 words
Conveyor and transfer system as claimed in claim 1, said suspension portion comprising a horizontal plate, and felt cushions mounted on said plate for sliding movement on said track means.
Claim 8
Dependent Claim
31 words
Conveyor and transfer system as claimed in claim 1, said suspension portion comprising a horizontally extending axle, and rollers rotatably mounted on said axle adapted to move along said track means.
Claim 9
Dependent Claim
28 words
Conveyor and transfer system as claimed in claim 1, said radially extending elements on said rod comprising blades extending transversely with respect to the direction of article conveyance.
Claim 10
Dependent Claim
56 words
Conveyor and transfer system as claimed in claim 1, each of said radially extending elements being of identical lengths, said elements being fastened to said rod at spaced elevations, said orientation elements being located at corresponding elevations, so as to effect transfer of selective ones of said supports having radially extending elements at said corresponding elevations.
