Abstract

452,897. Punching-machines. TRUSSEL MANUFACTURING CO., Poughkeepsie, New York, U.S.A. Dec. 5, 1935, No. 33778. Convention date, June 13. [Class 31 (ii)] [See also Group XVI] In a machine for punching holes in sheets, the sheet is positioned on a work table by a fixed front gauge, a movable back gauge and movable side gauges, and a common mechanism is provided for operating the three movable gauges and the punch or punches in definitely timed relation. The sheets 13 are removed by hand from a stacker 126, Fig. 3, having an inclined side 133 to stagger the sheets, and are placed on a table 17 where they are positioned by undercut side gauges 18, 19, a back gauge 14 and a front gauge 24, Fig. 6 ; they are then perforated by punches 87 and removed by hand to a stacker 127. The gauges 14, 18, 19 are adjustably secured to slides 29 movable in grooves 16, 22, 23 by screws 33 and slots 34, the screws engaging one of a number of holes 32 in the slides. The slides are actuated by levers 35, 36, 37 pivoted on studs 38, 39, 40 at the underside of the table and having pivoted links 41, 42, 43 connected to studs 44, 45, 46 on the slides. The levers are coupled together with lost motion by a link 65 having a slot 72, and a roller 68 and arm 70 and are urged towards their operative position by springs 58, 59, 60 from which they are withdrawn by a chain 50 controlled by a cam. The punches 87 reciprocate vertically in blocks 25 and have heads 84 engaged in a groove 83 in a row of blocks 80 whereby they are adjustable laterally. The blocks 80 are guided by short rollers 81 and a long roll 82 and are pivoted to a rockable member 76 by hinge tubes 79 bearing in blocks 78 attached to the member 76. Lubricant inserted in a hole 99 in a tube 79 issues between the tubes to oil the bearings. The member 76 is rocked about its shaft 109 by a pitman 74 connected to a crank on the shaft carrying the gauge controlling cam. When desired the gauge 18 may be fixed in a position in which it is not influenced by the cam, by engaging a screw 122 with holes 123, 124 in the slide 29 and groove 22. The other side gauge 19 and the back gauge 14 also remain stationary.
