ABSTRACT:
Apparatus for fragmenting or subdividing railroad rails wherein rails on tiltable platforms at the respective outer sides of two longitudinally extending, parallel sets of conveyors are lifted, one at a time, over fences on the platforms and onto the conveyors by rotatable fingers along the laterally inner edges of the platform. Inverted, shiftable T-shaped hooks engage and right tipped over rails on the conveyors prior to notching. Chisels on the ends of extensible and retractable plungers notch the outer edges of the base flanges of the rails. The notched rails advance toward holding and breaking stations and are held against upstanding, contoured walls by another set of plungers with one pair of the notches transversely aligned with breaking edges on the walls. A third set of plungers engage the portions of the rails that project unsupported beyond the breaking edges and bend these portions until separation occurs. A method of fragmenting or subdividing railroad rails is also disclosed, which includes the steps of transporting rails along longitudinally extending paths, righting tipped-over rails on the paths, substantially simultaneously inserting laterally oppositely arranged notches in the base flange of each rail, stopping the rails so that the sets of notches therein are aligned with breaking edges on upstanding, contoured walls along the inner sides of the paths, holding the rails against the contoured walls, and bending the unsupported portions of the rails until the unsupported portions break off.
