Abstract
Abstract A carriage is movable on rails at opposite lateral sides of which objects are to be deposited or picked up. A turnable shaft is provided on the carriage and connected with a parallelmovement linkage, including a toggle joint, to a free end of which there is connected a gripper for engaging objects to be conveyed. A cylinder and piston unit is connected with the pivot of the toggle joint, so that when the unit is operated, the latter collapses and the gripper engages from below an object to be lifted, whereupon turning of the shaft causes the parallel movement to perform an arcuate movement so that the object is moved from one side of the rails to the other for deposition thereat.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
255 words
In a conveying arrangement, a combination comprising a turnable shaft; at least one parallel-movement linkage comprising a first lever having an end portion pivoted about said shaft and a free end portion spaced from said pivoted end portion, a first arm pivoted on said free end portion of said first lever and having a free end, a second arm rigidly attached to said shaft so as to be turnable therewith and having a free end, and a second lever interconnecting said free ends of said arms in such a manner that said arms extend parallel to each other and said second lever extends parallel to said first lever; a toggle joint having two lever sections having respective free ends and respective pivotally connected ends, one of said free ends being connected with said free end portion of said first lever and the other of said free ends being connected with a stationary support; a cylinder-and-piston assembly fixedly mounted on said stationary support and having a piston rod connected with said connected ends of said lever sections for erecting and collapsing said toggle joint; and a load-engaging element having an engaging portion and rigidly connected to said second lever so as to be dis-placeable therewith for displacement of said engaging portion beneath a load to be engaged in response to the displacement of said toggle joint and for lifting displacement of such load, together with said engaging portion, from a first to an at least laterally spaced second position in response to turning of said shaft.
Claim 2
Dependent Claim
255 words
In a conveying arrangement, a combination comprising a turnable shaft; at least one parallel-movement linkage comprising a first lever having an end portion pivoted about said shaft and a free end portion spaced from said pivoted end portion, a first arm pivoted on said free end portion of said first lever and having a free end, a second arm rigidly attached to said shaft so as to be turnable therewith and having a free end, and a second lever interconnecting said free ends of said arms in such a manner that said arms extend parallel to each other and said second lever extends parallel to said first lever; a toggle joint having two lever sections having respective free ends and respective pivotally connected ends, one of said free ends being connected with said free end portion of said first lever and the other of said free ends being connected with a stationary support; a cylinder-and-piston assembly fixedly mounted on said stationary support and having a piston rod connected with said connected ends of said lever sections for erecting and collapsing said toggle joint; and a load-engaging element having an engaging portion and rigidly connected to said second lever so as to be dis-placeable therewith for displacement of said engaging portion beneath a load to be engaged in response to the displacement of said toggle joint and for lifting displacement of such load, together with said engaging portion, from a first to an at least laterally spaced second position in response to turning of said shaft.
Claim 3
Dependent Claim
18 words
A conveying arrangement as defined in claim 1; and mounting means turnably mounting said element on said linkage.
Claim 4
Dependent Claim
16 words
A conveying arrangement as defined in claim 1, wherein said shaft is turnable through substantially 180*.
Claim 5
Dependent Claim
60 words
A conveying arrangement as defined in claim 1, further comprising a gear drive having a first gear rigidly attached to said turnable shaft, and a second gear operatively associated with said first gear; and a cylinder-and-piston unit pivotably attached to said stationary support and having a piston rod pivotally connected to said second gear for effecting displacement of the same.
Claim 6
Dependent Claim
26 words
A conveying arrangement as defined in claim 4, said gear drive further comprising a drive chain engaging with said first and second gears in motion-transmitting relationship.
Claim 7
Dependent Claim
77 words
A conveying arrangement as defined in claim 1, further comprising a pivot connecting said free end of said second arm with said second lever for pivotal displacement of the latter in relation to the former in response to a displacement of said cylinder-and-piston assembly transmitted to said second lever by said toggle joint, said first lever and said first arm, and for a corresponding displacement of said load-engaging element about a pivot axis defined by said pivot.
Claim 8
Dependent Claim
16 words
A conveying arrangement as defined in claim 6, wherein said axis is at least substantially horizontal.
Claim 9
Dependent Claim
32 words
A conveyor arrangement as defined in claim 1, further comprising an additional parallel-movement linkage similar to and interconnected with said one parallel-movement linkage so as to move in concert with the same.
