Abstract
Abstract A load-carrying and positioning head for use in connection with jacks for handling vehicle transmissions or similar load lifting and handling devices, the head having a platform upon which the load rests, there being a plurality of arms carried by the platform and shiftable with respect thereto and into clamping engagement with the load when it is on the platform, there being chains cooperable with the platform for retaining the load thereon when the platform is tilted. The platform is carried by a mount which is coupled to the jack or the like, and is shiftable into plurality positions, there being a vertical axis coupling the mount and the platform whereby the platform may be rotated about a vertical axis with respect to the mount; there being a leveling link coupled with the mount, the mount having a transverse axis whereby the platform may be rotated about a horizontal axis; and there being a plate having a spherical surface carried by the platform and mating with a dished member, there being means for shifting the plate whereby the platform may be tilted from side to side.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A load-carrying and positioning head comprising: a platform for receiving said load; a plurality of arms shiftably carried by said platform, said arms each having a first stretch in the same plane as said platform and a second stretch in a laterally extending plane; means for locking said arms in a selected position with respect to said platform, said means including a locking device for said arms and engageable with the first stretch thereof; and means extending horizontally outwardly from the platform for supportingly receiving the first stretches and restricting shifting movement of said stretches toward and away from said platform to a substantially linear path.
Claim 2
Dependent Claim
106 words
A load-carrying and positioning head comprising: a platform for receiving said load; a plurality of arms shiftably carried by said platform, said arms each having a first stretch in the same plane as said platform and a second stretch in a laterally extending plane; means for locking said arms in a selected position with respect to said platform, said means including a locking device for said arms and engageable with the first stretch thereof; and means extending horizontally outwardly from the platform for supportingly receiving the first stretches and restricting shifting movement of said stretches toward and away from said platform to a substantially linear path.
Claim 3
Dependent Claim
21 words
A load-carrying and positioning head as set forth in claim 1, said locking device being carriEd by said outwardly extending means.
Claim 4
Dependent Claim
75 words
A load-carrying and positioning head for use with a lifting device comprising: a platform for receiving said load; a mount for said platform; and a plate carried by said platform therebeneath, said plate having a substantially spherical surface, the center of said surface being above the platform, said mount including a dished member carried by the mount and complementally receiving said plate, said plate and said dished member being shiftable with respect to each other.
Claim 5
Dependent Claim
75 words
A load-carrying and positioning head for use with a lifting device comprising: a platform for receiving said load; a mount for said platform; and a plate carried by said platform therebeneath, said plate having a substantially spherical surface, the center of said surface being above the platform, said mount including a dished member carried by the mount and complementally receiving said plate, said plate and said dished member being shiftable with respect to each other.
Claim 6
Dependent Claim
104 words
A load-carrying and positioning head for use with a lifting device comprising: a platform for receiving said load; a mount for said platform; a plate carried by said platform therebeneath, said plate having a substantially spherical surface, said mount including a dished member carried by the mount and complementally receiving said plate, said plate and said dished member being shiftable with respect to each other; and means for shifting said plate with respect to said dished member, said means including a shaft coupled with said plate, rotation of said shaft causing said platform to tilt from side to side with respect to said device.
Claim 7
Dependent Claim
104 words
A load-carrying and positioning head for use with a lifting device comprising: a platform for receiving said load; a mount for said platform; a plate carried by said platform therebeneath, said plate having a substantially spherical surface, said mount including a dished member carried by the mount and complementally receiving said plate, said plate and said dished member being shiftable with respect to each other; and means for shifting said plate with respect to said dished member, said means including a shaft coupled with said plate, rotation of said shaft causing said platform to tilt from side to side with respect to said device.
