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 vertical component, axle means for supporting a cylinder horizontally on said vertical component, a rotatable cylinder mounted horizontally on said axle means, at least two parallel elements having means 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 and means for releasing said cylinder from a fixed position.

Claim 3

The device of claim 1 wherein said means for engagement with the edges of said bumper are notches in the upper surface of said elements.

Claim 4

The device of claim 1 wherein said means for holding said bumper in position when it is engaged with said engaging means is a belt having one end fixed to a rotatable support mounted at one of the ends of said parallel elements and the other end engageable with a support mounted between the opposite ends of said parallel elements, whereby when said bumper is engaged with said engagement means, said belt is lapped over said bumper and engaged with said support at the opposite ends of said parallel elements, and said rotatable support is rotated to tighten said belt against said bumper.

Claim 5

The device of claim 1 wherein said means for holding said rotatable cylinder in a fixed position is a flexible brake band lapping said cylinder having one end attached to one side of said vertical component and the other end spring biased against a retaining means on the opposite side of said vertical component, whereby said brake band is drawn tightly around an arc portion of said cylinder holding it in a fixed position.

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 orifice therein horizontally mounted between said rails; a bar horizontally mounted between said rails and extending across a portion of said opening in said web; a cylindrical hub horizontally mounted on said I-beam between said rails above said web; 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, one end of said shaft being aDapted to receive a means for rotating said shaft; a pawl mounted on one of said plates engageable with said ratchet wheel; a belt having one end fixed to said rotary shaft and the other end engageable with said catch bar; 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 orifice in said outwardly extending retaining plate horizontally mounted on said I-beam, and which is spring biased against the underneath side of said plate; and a foot pedal having a first and second end extending through said opening in said web of said I-beam fulcrumed on said bar across said opening, 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 the brake band and allowing the cylinder to be rotated to a new position.

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 orifice therein horizontally mounted between said rails; a bar horizontally mounted between said rails and extending across a portion of said opening in said web; a cylindrical hub horizontally mounted on said I-beam between said rails above said web; 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, one end of said shaft being aDapted to receive a means for rotating said shaft; a pawl mounted on one of said plates engageable with said ratchet wheel; a belt having one end fixed to said rotary shaft and the other end engageable with said catch bar; 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 orifice in said outwardly extending retaining plate horizontally mounted on said I-beam, and which is spring biased against the underneath side of said plate; and a foot pedal having a first and second end extending through said opening in said web of said I-beam fulcrumed on said bar across said opening, 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 the brake band and allowing the cylinder to be rotated to a new position.

Claim 8

An adjustable device for holding a workpiece while work is being performed on it, comprising: a. support means having a vertical component, b. axle means for supporting a cylinder horizontally on said vertical component, c. a rotatable cylinder mounted horizontally on said axle means, d. means mounted on said cylinder for retaining a workpiece, e. braking means for holding said cylinder in a fixed position comprising a flexible element lapping around an arc of said cylinder having one end fixed and the other end spring biased against a retaining means, whereby said flexible element is drawn tightly around an arc portion of said cylinder holding it in a fixed position, and, f. means for releasing the braking action of said flexible element.

Claim 9

An adjustable device for holding a workpiece while work is being performed on it, comprising: a. support means having a vertical component, b. axle means for supporting a cylinder horizontally on said vertical component, c. a rotatable cylinder mounted horizontally on said axle means, d. means mounted on said cylinder for retaining a workpiece, e. braking means for holding said cylinder in a fixed position comprising a flexible element lapping around an arc of said cylinder having one end fixed and the other end spring biased against a retaining means, whereby said flexible element is drawn tightly around an arc portion of said cylinder holding it in a fixed position, and, f. means for releasing the braking action of said flexible element.

Claim 10

The adjustable device as claimed in claim 6 in which said releasing means comprises a foot pedal.
