Abstract

Abstract A wire clamping clip for mounting on a stucco wall is constructed as a block member having a workpiece engaging surface and an exposed top surface. A recess is formed in the workpiece engaging surface for receiving a wire. A throughbore is formed in the block adjacent to the recess and a plastic bushing having a cross sectional dimension of the same shape and slightly smaller than the cross sectional dimension of the throughbore is positioned in the throughbore. A hardened pin with a sharpened end is slidingly received in a tight frictional engagement through the center of the plastic bushing and has an enlarged head for abutting against the top end of said bushing and having a length longer than said bushing so that its sharpened end extends beyond the lower end of said bushing.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 192 words
A wire clamping clip for mounting on a stucco wall comprising a block member having a workpiece engaging surface and an exposed top surface, a recess formed in the workpiece engaging surface completely traversing said surface in a predetermined direction for receiving a wire, a throughbore formed in said block adjacent to said recess and in a normal relation therewith, a plastic bushing having a cross sectional dimension of the same shape and and slightly smaller than the cross sectional dimension of said throughbore and having a tapered nose portion at its lower end, said throughbore has a polygonal cross section and the exterior of said bushing has a conforming polygonal cross sectional shape to prevent rotational movement of said block member about said bushing, the length of said bushing being substantially longer than said throughbore, and a haredened pin with a sharpened end slidingly received in a tight frictional engagement through the center of said plastic bushing with an enlarged head for abutting against the top end of said bushing and having a length longer than said bushing so that its sharpened end extends beyond the lower end of said bushing.
Claim 2
Dependent Claim 192 words
A wire clamping clip for mounting on a stucco wall comprising a block member having a workpiece engaging surface and an exposed top surface, a recess formed in the workpiece engaging surface completely traversing said surface in a predetermined direction for receiving a wire, a throughbore formed in said block adjacent to said recess and in a normal relation therewith, a plastic bushing having a cross sectional dimension of the same shape and and slightly smaller than the cross sectional dimension of said throughbore and having a tapered nose portion at its lower end, said throughbore has a polygonal cross section and the exterior of said bushing has a conforming polygonal cross sectional shape to prevent rotational movement of said block member about said bushing, the length of said bushing being substantially longer than said throughbore, and a haredened pin with a sharpened end slidingly received in a tight frictional engagement through the center of said plastic bushing with an enlarged head for abutting against the top end of said bushing and having a length longer than said bushing so that its sharpened end extends beyond the lower end of said bushing.
Claim 3
Dependent Claim 190 words
A wire clamping clip for mounting on a stucco wall comprising a block member having a workpiece engaging surface and an exposed top surface, a recess formed in the workpiece engaging surface completely traversing said surface in a predetermined direction for receiving a wire, a throughbore formed in said block adjacent to said recess and ina normal relation therewith, a plastic bushing having a cross sectional dimension of the same shape and slightly smaller than the cross sectional dimension of said throughbore and having a tapered nose portion at its lower end, said throughbore has a polygonal cross section and the exterior of said bushing has a conforming polygonal cross sectional shape to prevent rotational movement of said block member about said bushing, the length of said bushing being substantially longer than said throughbore, and a hardened pin with a sharpened end slidingly received in a tight frictional engagement through the center of said plastic bushing with an enlarged head for abutting against the top end of said bushing and having a length longer than said bushing so that its sharpened end extends beyond the lower end of said bushing.
