Abstract
An anti-slip wooden handle for a hand-held striking tool, and a method of making the same, embody the provision in the handle of grooves formed in a gripping surface by die-pressing at high temperature, so as to minimize slipping of the handle when in use, while also minimizing hand irritation.
Claims6
In a method of making a wooden handle for a hand-held striking tool, said handle including a gripping portion having a substantially elliptical cross-sectional configuration providing a pair of opposed relatively wide gripping surfaces and a pair of opposed relatively narrow gripping surfaces, the improvement comprising die-pressing a plurality of spaced-apart non-intersecting grooves into a relatively wide gripping surface, said grooves having a width of about 1/64 to 1/32 inch and a depth of about 1/64 to 3/64 inch, for minimizing slipping of the handle in the hand during use of the tool, said die-pressing taking place at a die temperature of about 550.degree. F. to 1000.degree. F. and a die pressure of about 1200 to 9300 pounds per square inch to provide grooves substantially free of abrasiveness and splinter formation.
In a method of making a wooden hand-held hammer handle including a gripping portion having a substantially elliptical cross-sectional configuration providing a pair of opposed relatively wide gripping surfaces and a pair of opposed relatively narrow gripping surfaces, the improvement comprising die pressing a plurality of non-intersecting grooves including a longitudinal row of spaced-apart substantially parallel grooves into each of the relatively wide gripping surfaces, said grooves having a width of about 1/32 inch and a depth of about 1/32 inch for minimizing slipping of the handle in the hand during use of the tool, said die-pressing taking place at a die temperature of about 850.degree. F. to 950.degree. F. and a die pressure of about 1200 to 4000 pounds per square inch to provide grooves substantially free of abrasiveness and splinter formation.
