Abstract

1461261 Punching apparatus L K BILLOWS 7 Jan 1974 [10 Jan 1973] 1264/73 Heading B4B [Also in Division B3] A punch mechanism for punching holes in carrier sheets and plates used in printing comprises a punch member 13 slidably mounted in a guide 10, two cam members 6, 7 being provided to impart reciprocatory motion to the punch member upon unidirectional rotation of the cam. The cam members are rotatably mounted in a housing 2 and each provided with mirror image cam tracks 8 each adapted to engage a respective end of a pin 15 passing through a head 14 formed on the punch 13; the cam members are keyed to a shaft 9 which is rotatable by a handle 30. A stop plate 23 for engagement with the edge of a sheet is slidably mounted in the housing, its position relative to the punch being set by a cam member 25 secured to a rotatable spindle 19; an index plate 26 is provided on the spindle. Heavy rotatable bars 32, Fig. 2, are provided for holding down the sheet material, clearance 33 being formed in the housing to permit the bars to lift when the material is inserted thereunder. In a modification, several punch mechanisms may be connected to a common shaft 9 so that several holes may be punched at one time.
