| Abstract: |
Disclosed is a tool for use in spreading soft, malleable materials along an inner corner formed by angular surfaces. The tool has a relatively hard core and an elastomeric covering on the core together forming a spreading nose for the tool. The tool has a handle for the spreading nose. The elastomeric covering is a soft, resilient material so that it will seal against the angular surfaces of the inner corner where the material is being spread, even if those surfaces are somewhat irregular, for confining the soft spreading material and inhibiting it from spreading around a working edge of the tool except at a tip where a bead is formed.

First Claim:
Show all 7 claims |
Having thus described my invention, I claim:
1. A tool for use in spreading soft, malleable material along an inner corner formed by angular surfaces, comprising:
- a hard core with an elastomeric covering, having a durometer hardness in the range from 20 to 70 Shore A, on said core together forming a spreading nose for said tool;
- a handle for said spreading nose;
- said elastomeric covering tapering inwardly and longitudinally, forming an apex angle in the range from 20 to 90 degrees, to a narrow tip;
- said elastomeric covering having a working edge with longitudinally converging portions for engaging the angular surfaces of the inner corner;
- said working edge having a blunt tip to form a bead of soft malleable material at said corner;
- said elastomeric covering supporting said working edge having substantially uniform thickness of up to substantially 1/8 inch and said core providing substantially uniform support to said working edge such that said elastomeric covering compresses and said working edge conforms and seals against the angular surfaces, even if said angular surfaces are somewhat irregular, when said spreading nose is pressed and pulled along the inner corner for substantially confining said soft malleable material to said spreading nose and a uniform bead formed by the blunt tip of said working edge at the inner corner.
