ABSTRACT:
A pitcher's rubber construction having a casing partially embedded in a pitching mound with the upper end substantially flat with the ground. A pitcher's rubber is attached to the top of the casing. The rubber is attached to the casing by a pair of spaced apart guide ways formed in the casing and a pair of spaced apart runners formed on the interior of the rubber. The spacing of the runners corresponds to the spacing of the guide ways whereby the pitcher's rubber, through alignment of the runners with the guide ways, will longitudinally slide relative to the casing. The rubber is locked to the casing by a resiliently biased plunger extending upwardly through a guideway and plunger-receiving recesses formed in one of the runners. The position of the recess relative to the plunger is such that when the rubber is slidably moved along the casing, the plunger will be biased into the recess and thereby lock the rubber in place on the casing.
