Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 116 words
An adjustable roller support attachment for mounting on a clamping type work bench to facilitate the handling of long stock in stationary power tools, comprising a roller means, a support for the roller means, the support having a wide, elongated base for clamping engagement by the work bench, a stabilizing element forming an opening for receiving the support base, the stabilizing element having a stabilizing surface adjacent the opening for resting on the work bench, and means for releasably securing the stabilizing element to the support base whereby the stabilizing element assists in stabilizing the support and roller means on the work bench and facilitates height adjustment of the roller support attachment on the work bench.
Claim 2
Dependent Claim 116 words
An adjustable roller support attachment for mounting on a clamping type work bench to facilitate the handling of long stock in stationary power tools, comprising a roller means, a support for the roller means, the support having a wide, elongated base for clamping engagement by the work bench, a stabilizing element forming an opening for receiving the support base, the stabilizing element having a stabilizing surface adjacent the opening for resting on the work bench, and means for releasably securing the stabilizing element to the support base whereby the stabilizing element assists in stabilizing the support and roller means on the work bench and facilitates height adjustment of the roller support attachment on the work bench.
Claim 3
Dependent Claim 36 words
The adjustable roller support attachment of claim 1 wherein the means for releasably securing the stabilizing element to the support base comprises a screw means threaded through the stabilizing element for engagement with the support base.
Claim 4
Dependent Claim 54 words
The adjustable roller support attachment of claim 1 wherein the support base is of generally uniform thickness and substantial width to facilitate its firm attachment or purchase by vise jaws in the work bench, the support base being of substantial length to facilitate height adjustment of the roller support attachment on the work bench.
