Abstract
An apparatus comprising a grinding unit supported on and movable along a transversal beam provided in a wagon which is movable along a pair of spaced rails. The grinding unit includes a stationary frame on which a transversal beam is movably supported. A shaft member is rotatably mounted in a hollow member secured to said transversal beam and has fork-shaped frames fixed to the lower end thereof. A frame is pivotably supported between the lower ends of the fork-shaped frames and has a shaft bearing sleeve secured to a front portion of said frame. A grinder wheel shaft carries a grinding wheel and is rotatably received in the shaft bearing sleeve. There is provided means for swinging said fork-shaped frames about an axis of said shaft member. Cam means are mounted on the underside of a base member secured to the top of the hollow member to define a gap therebetween. A roller is rotatably supported on the top of a L-shaped link pivoted to the top of the fork-shaped frames and is received in the gap to roll along said cam means. The other end of the L-shaped link is linked through to the shaft bearing sleeve on said frame.
