Abstract
Abstract A metal washer with resilient tabs extending from its circumferential periphery is used to support an anchoring member, such as a stud, bolt and the like within the barrel of a stud setting apparatus. The tabs have a thickness less than the washer and the roots of the tabs are located inwardly from the circumferential periphery of the remainder of the washer. Preferably, the tabs are equiangularly spaced about the periphery of the washer and the tabs and washer are formed from a single piece of metal. When positioned on the shank of an anchoring member and inserted into the barrel of a stud setting apparatus, the tabs are bent out of the plane of the washer and provide a resilient support in contact with the surface of the barrel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
218 words
A metal washer for supporting an anchoring member, such as a bolt, stud and the like, within the barrel of a stud setting apparatus from which the anchoring member is driven into a hard target material, such as concrete, steel and the like, said washer having a flat configuration with an opening centrally arranged therethrough for an anchoring member, wherein the improvement comprises that said washer has a circumferential peripheral edge having a diameter such that said peripheral edge affords a guiding action on the surface of the barrel for the anchoring member as it is driven from the barrel, at least one resilient tab formed on said washer and arranged in the plane of said washer, said tab extending radially outwardly beyond said peripheral edge so that when inserted into the barrel of the stud setting apparatus the radially outer end of said tab deflects out of the plane of said washer and resiliently supports the anchoring member within the barrel, and said tab having side edges extending inwardly from its radially outer end to a point on said washer spaced radially inwardly from said circumferential peripheral edge, the radial extent of said tab radially inwardly of said circumferential peripheral edge being at least equal to the radial extent of said tab radially outwardly of said edge.
Claim 2
Dependent Claim

A metal washer for supporting an anchoring member, such as a bolt, stud and the like, within the barrel of a stud setting apparatus from which the anchoring member is driven into a hard target material, such as concrete, steel and the like, said washer having a flat configuration with an opening centrally arranged therethrough for an anchoring member, wherein the improvement comprises that said washer has a circumferential peripheral edge having a diameter such that said peripheral edge affords a guiding action on the surface of the barrel for the anchoring member as it is driven from the barrel, at least one resilient tab formed on said washer and arranged in the plane of said washer, said tab extending radially outwardly beyond said peripheral edge so that when inserted into the barrel of the stud setting apparatus the radially outer end of said tab deflects out of the plane of said washer and resiliently supports the anchoring member within the barrel, and said tab having side edges extending inwardly from its radially outer end to a point on said washer spaced radially inwardly from said circumferential peripheral edge, the radial extent of said tab radially inwardly of said circumferential peripheral edge being at least equal to the radial extent of said tab radially outwardly of said edge.
Claim 3
Dependent Claim
34 words
A metal washer, as set forth in claim 1, wherein said tab having a thickness dimension in the axial direction of said washer which is less than the corresponding thickness dimension of said washer.
Claim 4
Dependent Claim
20 words
A metal washer, as set forth in claim 1, wherein said washer and tab being formed as a unitary member.
Claim 5
Dependent Claim
26 words
A metal washer, as set forth in claim 1, wherein three said tabs are formed on and are positioned at equiangularly spaced locations about said washer.
Claim 6
Dependent Claim
57 words
A metal washer, as set forth in claim 4, wherein the sides of each said tab are arranged converging toward one another in the direction toward the radially outer end thereof and a recess formed on each side of each said tab projecting inwardly from said circumferential peripheral edge to the radially inner end of said tab.
