ALLIGATOR POWER SHEARS BY J. H. CHANCYForeman Blacksmith Shop, Georgia Railroad, Augusta, Ga. The drawings show a home made power shear which wasbuilt in the Augusta shops of the Georgia Railroad to re-place an old pneumatic shear, by the use of which a greatincrease in the capacity for cutting up material has been. some of the parts were designed especially for this will be seen by an inspection of the drawings, the mov-able shear plate is operated by a cam on a 3J^-in. shaft. While, no doubt, a machine could have been purchased inthe market which would possess some advantages over theone described, the service which this machine is renderingis entirely satisfactory and its construction was taken careof without interfering with the regular work of the shop.
