Abstract

619,388. Punching presses. LOTUS, Ltd., BOSTOCK, G. S., and SHARPLES, T. G. Dec. 6, 1946, No. 36095. [Class 31(ii)] A punch-carrying plate of the type used in presses for producing perforated patterns in shoe uppers has a set of holes of standardized diameter equal to the external diameter of the wider end of punches to be used therewith, the latter having different internal diameters and being interchangeable in the holes in the punchcarrying plate so as to produce various patterns. Fig. 1 shows the complete die comprising a base plate 9 and removable punch-carrying plate 13, located and secured on the base plate by dowel pins 9b and screws 18; resiliently mounted on the base plate is a presser plate 10 having an aperture corresponding to the shape of the punch-carrying plate 13 and having a cover plate 15 which is perforated at 15a corresponding to the pattern to be punched to permit free passage of the punches and which is provided with work locating and holding members 17 and 16. The base plate 9 and punch-carrying plate 13, (see also Fig. 4), have aligned perforations, those in the punch-carrying plate 13 being adapted to receive individual punches 14 according to the pattern desired, and those in the base plate 9 being large enough to permit passage of the largest waste discs which will be produced by the range of punches to be used.
