Abstract
Abstract A suspension yoke for the conveyance of goods along various conveying devices has wheels set at such an angle that when the wheels engage a rotating tube or like means the suspension yoke is advanced along the tube by the rotary movement imparted to the wheels by the rotation of the tube, hook means so arranged that when the hook means engages the screw thread of a rotating conveyor screw the suspension yoke is advanced along the screw by the rotation thereof, and a roller so mounted that when the roller engages a downwardly inclining rod or like element the suspension yoke is advanced along the rod by gravity.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
176 words
A universal suspension yoke for use in a conveyor system including separate and independent rotating tube conveyors, screw conveyors, and inclined rod conveyors, said suspension yoke comprising: a yoke frame; wheel means rotatably mounted at an angle on said yoke frame for selective independent engagement with a rotating tube conveyor of said conveyor system and for imparting movement to said suspension yoke along said rotating tube conveyor; hook means mounted on said yoke frame for selective independent engagement with a screw conveyor of said conveyor system and for imparting movement to said suspension yoke along said screw conveyor; roller means rotatably mounted on said yoke frame for selective independent engagement with an inclined rod conveyor of said conveyor system and for allowing downward movement of said suspension yoke due to the effect of gravity thereon along said inclined rod conveyor; and said wheel means, said hook means, and said roller means being mounted on said yoke frame for separate and nonsimultaneous movement along said rotating tube conveyor, said screw conveyor, and said inclined rod conveyor, respectively.
Claim 2
Dependent Claim
176 words
A universal suspension yoke for use in a conveyor system including separate and independent rotating tube conveyors, screw conveyors, and inclined rod conveyors, said suspension yoke comprising: a yoke frame; wheel means rotatably mounted at an angle on said yoke frame for selective independent engagement with a rotating tube conveyor of said conveyor system and for imparting movement to said suspension yoke along said rotating tube conveyor; hook means mounted on said yoke frame for selective independent engagement with a screw conveyor of said conveyor system and for imparting movement to said suspension yoke along said screw conveyor; roller means rotatably mounted on said yoke frame for selective independent engagement with an inclined rod conveyor of said conveyor system and for allowing downward movement of said suspension yoke due to the effect of gravity thereon along said inclined rod conveyor; and said wheel means, said hook means, and said roller means being mounted on said yoke frame for separate and nonsimultaneous movement along said rotating tube conveyor, said screw conveyor, and said inclined rod conveyor, respectively.
