Adjustable holding device

Claim 2

An adjustable device for holding a workpiece while work is being performed on it comprising a support means having a lower and an upper vertical component, axle means horizontally mounted on said upper vertical component, a rotatable cylinder concentrically mounted on said axle means, means having elements for engagement with the edges of a bumper mounted on said rotatable cylinder, means for holding said bumper in position on said elements, means peripherally engaging said rotatable cylinder for holding said rotatable cylinder in a fixed position, means for releasing said cylinder from a fixed position, and means to pivotally support said upper component on said lower vertical component.

Claim 3

In the device as defined in claim 1, said pivotal support comprising a cradle assembly between said lower and said upper component to permit angular adjustment of said upper component relative to said lower component.

Claim 4

In the device as defined in claim 2, said means for holding and releasing said cylinder being adaptable to simultaneously lock said cradle assembly against relative rocking movement.

Claim 5

The device of claim 3 wherein said means for holding said rotatable cylinder in a fixed position is a flexible brake band lapping said cylinder and having one end attached to one side of said lower vertical component and the other end is spring biased against a retaining means on the opposite side of said lower vertical component, whereby said brake band is drawn tightly around an arc portion of said cylinder holding it in a fixed position, and locking said upper component to said lower component.

Claim 6

An adjustable device for holding an automobile bumper and the like while work is being performed on it comprising a base, an I-beam vertically mounted on said base, said I-beam comprising two parallel rails joined by a web which extends between said rails and which has an opening near said base; an outwardly extending retaining plate having an aperture therein horizontally mounted between said rails; a work support pivotally mounted on top of said I-beam for angular adjustment relative thereto; a cylindrical hub horizontally mounted on said work support between spaced side plates; a rotatable cylinder concentrically mounted around said hub; at least two holding plates having notched upper surfaces mounted in parallel on said rotatable cylinder, said holding plates having a catch bar mounted therebetween at one of their ends, and a shaft having a ratchet wheel attached thereto mounted at the other of their ends; a flexible brake band lapping the top portion of said cylinder, one end of said band being fastened to one side of said I-beam and the other end having a bolt attached thereto which extends downwardly through said aperture in said outwardly extending retaining plate horizontally mounted on said I-beam, and which is spring biased against the underneath side Of said plate to tension said brake band to thereby lock said cylinder against rotation and said work support against angular displacement; a foot pedal having a first and second end extending through said opening in said web of said I-beam fulcrumed on said I-beam, said first end of said pedal being located under said bolt whereby a downward force on said second end of said pedal compresses said spring thus relieving the tension on said brake band and allowing said cylinder to be rotated to a new position and said work support to be angularily adjusted relative to said I-beam.

Claim 7

An adjustable device for holding an automobile bumper and the like while work is being performed on it comprising a base, an I-beam vertically mounted on said base, said I-beam comprising two parallel rails joined by a web which extends between said rails and which has an opening near said base; an outwardly extending retaining plate having an aperture therein horizontally mounted between said rails; a work support pivotally mounted on top of said I-beam for angular adjustment relative thereto; a cylindrical hub horizontally mounted on said work support between spaced side plates; a rotatable cylinder concentrically mounted around said hub; at least two holding plates having notched upper surfaces mounted in parallel on said rotatable cylinder, said holding plates having a catch bar mounted therebetween at one of their ends, and a shaft having a ratchet wheel attached thereto mounted at the other of their ends; a flexible brake band lapping the top portion of said cylinder, one end of said band being fastened to one side of said I-beam and the other end having a bolt attached thereto which extends downwardly through said aperture in said outwardly extending retaining plate horizontally mounted on said I-beam, and which is spring biased against the underneath side Of said plate to tension said brake band to thereby lock said cylinder against rotation and said work support against angular displacement; a foot pedal having a first and second end extending through said opening in said web of said I-beam fulcrumed on said I-beam, said first end of said pedal being located under said bolt whereby a downward force on said second end of said pedal compresses said spring thus relieving the tension on said brake band and allowing said cylinder to be rotated to a new position and said work support to be angularily adjusted relative to said I-beam.
