Abstract
982,803. Stencil switches. SPERRY RAND CORPORATION. July 13, 1962 [Aug. 10, 1961], No. 27009/62. Heading H2B. A sensing unit for detecting holes 23 in an information card 22 as it passes over a conductive roller 21 comprises a brush assembly 24 wherein the connections from individual leads 76 to a plurality of brushes 36 are made by means of a printed-circuit board 20 so that the brush assembly is readily removable without interference with the individual leads. Brushes 36 extend from strips 26 which are mounted in slots in an insulating bar 29 pivoted in a framework 14 comprising channel member 16. 17, which are carried on the main body of the machine 10 by engagement in mating grooves on a bracketed support 13. Each strip 26 is secured in position and electrically connected to a corresponding strip 27 by a bolt 37, and the ends 34 of the strips 27 engage respective conductive elements 28 on the printed circuit board 20. The assembly is removed by sliding from the machine after first rotating a hand wheel (Figs. 1 and 2, not shown), which turns bar 29 to bring the brushes 36 and ends 34 into the gaps 14E and 14B respectively, and moves a detent arm 43 clear of the body of the machine. In a modification (Figs. 11 and 12, not shown), the printed-circuit board is arranged to one side of (instead of above) the brush assembly and the ends of strips 26 engage the board directly.
