Apparatus and method for securing a tubular workpiece in position on a support
First Claim
1. A device for maintaining a workpiece in position on a support, comprising:
- a body;
clamping means for affixing said body to said support; and
stationary retainer means provided on said body for engaging said workpiece and fixing the position of said workpiece relative to said support, said retainer means comprising an upwardly facing slot formed in said body and adapted to receive said workpiece therein, said slot being provided with a decreasing transverse dimension toward the lower portion of said body so that downward movement of said workpiece in said slot causes engagement of said workpiece with the walls of said slot.

Abstract
An apparatus and method for maintaining a tubular workpiece in position on a support, such as a ladder or the like, preferably comprises a pair of bodies adapted for connection to the support, with one of the bodies being positioned on either side thereof, such as to the stiles of the ladder. A clamping assembly including a clamping plate secures the bodies to the ladder stiles in a predetermined position on the ladder and at a predetermined angular orientation. Each body is provided with an upwardly facing slot having a width which decreases toward the lower portion of the body, with the slots being adapted to receive the workpiece therein. Downward movement of the workpiece into the slots results in frictional engagement of the workpiece with the slot walls to secure the workpiece in position. The workpiece is removed by exerting an upward force thereon and disengaging the workpiece from the slot walls.

8. An assembly for maintaining a workpiece in position on a ladder or the like including a pair of spaced upright members, comprising:
-
a first body; a second body; first clamping means for affixing said first body to one of said upright members; second clamping means for affixing said second body to the other of said upright members; and stationary retainer means provided on each of said bodies for providing engagement of said workpiece at spaced locations and fixing the position of said workpiece; wherein a rearward portion of each of said first and second bodies is adapted for engagement with its respective upright member, and wherein said stationary retainer means is provided on a forward portion of each of said first and second bodies, and wherein said stationary retainer means comprises an upwardly facing slot formed in each said body, each said slot being provided with an entrance having a sufficient transverse dimension to receive said workpiece therein, and being defined by tapered walls which cooperate to provide a decreasing transverse dimension to said slot toward the lower portion of said body, so that downward movement of said workpiece in the slots formed in said first and second bodies results in engagement of said workpiece with the walls of said slots to frictionally engage said workpiece with said first and second bodies. - View Dependent Claims (9, 10)
