Title: Improvements in or relating to Means for Supporting Iron or Steel Plates and Moving them into Correct Position during the Operation of Punching or Shearing such Plates, with Special Reference to its use in Working Ship Plates.
Inventor: NICHOLSON FREDERICK
IPC: B21D28/26
Filed: 1917-10-22
Abstract: 119,565. Nicholson, F. Oct. 22, 1917. Metal-sheet feeds.-Ship plates and other metal plates are advanced to punching or shearing machines by means of a carrier which moves longitudinally in a slide which can be adjusted transversely by the operator. The slide is moved intermittingly or continuously by hand or power controlled mechanism. Gauging means are provided for assisting the correct feed of the work. The work is clamped, on to a slide M, Fig. 7, fitted on its underside with a rack N, and provided with adjustable gauges 0 which are fixed in the required positions in the slide M by means of bolts with T-heads which move in slots in the slide and are fixed in the desired position by nuts R, screws T being provided for fixing the work in the desired position. The slide M can be adjusted longitudinally relatively to two bearer or guide bars E which form part of a transversely movable carrier shown in Fig. 4, and comprising six or more slides C which can move transversely on corresponding bearers A, Fig. 10, which are mounted on concrete pillars. The slides C are connected by bars D so as to move together, and are fitted with rollers Z, Z<2> which support the work in part. The forward movement of the work is effected by rotation of a hand-wheel W, Fig. 10, on a shaft P which is geared to the rack N. An adjacent wheel K actuates through worm-gearing a shaft G which is fitted with gear wheels which engage racks on the slides C, and the transverse movement is thus obtained. The extent of these movements is controlled by a pointer 12, Fig. 10, and a scale on a rod X fixed to the transverse member, and by means of a pointer on a bar U which co-operates with a scale which may be clipped to the work under treatment. For use in connexion with two punching machines arranged parallel td each other, hand-operated winches are employed to actuate ropes which move the work from one feeding apparatus to another, so that two rows of holes may be punched in each plate without turning them end for end.
