Title: Improvements in or relating to machines for moulding shoe-heel stiffeners
IPC: A43D8/00
Filed: 1945-04-13
Abstract: 590,127. Moulding shoe-stiffeners &c. CHAMBERLAIN, W. H. April 13, 1945, No. 9259. [Class 17 (i)] The wiper plate h by which a flange or seating is moulded on a stationary heel stiffener blank x is pressed outwards from the slide a by which it is reciprocated, by relative movement between the plate h and a slide a, during the operative stroke, and the pressure on the plate h is relieved during the return stroke. Heavy pressure may thus be exerted against the blank during the operative stroke while during the return stroke this pressure is relieved and dragging on the material of the blank avoided. In one form, Fig. 2, the slide a accommodates in a recess f in its rear face the wiper plate h and a plate g, the plate g and inner face of recess f being tapered at the same angle, as shown. A connecting rod d, by which the slide a is operated, is attached at its lower end to a lever j centrally pivoted on a pen k in lugs m on the slide, a ball or finger n at the opposite end of the lever j engaging a rounded hole oin the plate g. During the downward operative stroke of the rod d and slide a relative movement occurs between the plate g and slide a in the direction of movement opposite to that of the slide to press the plate h outwards in the recess f against the blank x as the flange thereon is produced. The reverse occurs on the upward stroke. In a modification, the connecting rod is attached to a member rigidly secured to a tapered backing plate in a recess in the slide, the plate and recess being tapered in opposite directions to those in the example described above. Specifications 482,761 and 488,453 are referred to.
