Definitions

  • This invention relates generally to machinery for handling data-tabulating cards, and in particular to an improved card-punching mechanism.
  • Information is entered on tabulating cards by coded combinations of holes punched in the cards.
  • Machinery in which the present invention may be used is designed to perform this punching operation.
  • cardpunching machinery employs a line of punching tools, one such tool for each of the hole locations in a line extending along the width or length dimension of the card. All the punching tools of the line are actuated by a single striker bar which reciprocates at a distance therefrom, and a punching tool selection mechanism is interposed between the striker bar and the line of punching tools to select which of the punching tools shall be actuated and which shall be idle on each particular actuating stroke of the striker bar.
  • the striker bar keeps reciprocating very rapidly so as to provide a drive which is continuously available whenever a particular combination of punching tools is selected for actuation.
  • Tabulating cards are fed past the operating location of the punching tools at a rather high rate, and each of, for example, twelve rows of holes on each card are punched in rapid succession. In high speed data-processing this operation may have to be repeated at punching speeds of the order of 75 rows per second.
  • the punching mechanism must be capable of 75 punching operations per second; therefore the striker bar must reciprocate at a rate of 75 cycles per second throughout operation of the card-punching machine, whether or not cards are actually being punched at any given moment.
  • this invention aims to provide a mechanism of this type which completely eliminates sliding friction in the suspension of the reciprocating striker bar. Another object is to provide a striker bar suspension which is inexpensive to manufacture.
  • An illustrative example of a punching mechanism embodying this invention comprises apparatus formed with a cutting surface and including actuating means effective in response to movement in a selected direction to drive the cutting surface operatively against the material to be punched. Then there is provided at least one flexible member supporting the actuating means, and being sufficicntly bendable to permit the required movement of the actuating means.
  • FIGS. IA through C are a sequence of side elevational views, with parts broken away, sectioned, or removed for clarity of illustration, showing successive stages in the operation of a card-punching mechanism with which the present invention may be employed, with FIGS. IB and C illustrating a striker bar suspension in accordance with this invention;
  • FIG. ID is a front elevational view, also with parts broken away, sectioned, and omitted, of the mechanism of FIGS. IA through C;
  • FIG. IE is an enlarged detail of FIG. ID
  • FIG. 11 is a side elevational view of an alternative embodiment of a striker bar suspension in accordance with this invention.
  • FIG. IA illustrates a card-punching mechanism of the type which pro vides a typical environment for the reciprocating suspension of this invention.
  • a punching tool it the upper part of which is seen in FIG. IA, is vertically oriented and is mounted, in a manner which will subsequently be discussed, for a vertical movement in which it is driven downwardly against the material to be punched, e.g. a tabulating card, and is subsequently pulled upwmdly to extract it from the punched hole.
  • the downward impetus is applied to the punching tool it by a striker bar 12 which reciprocates vertically, as indicated by arrows A.
  • the punching tool 10 would generally be one of, for example, up to eighty such punching tools arranged in a row extending perpendicularly to the plane of FIG. IA.
  • the reciprocating striker bar 12 which is seen in section in FIG. 1A, also extends perpendicularly to the plane of that figure and parallel to the row of punching tools 16, so as to be able to actuate all of the eighty individual punching tools in the row.
  • the full length of the striker bar 12 is seen in FIG. ID.
  • selector mechanisms 14- each interposed between the striker bar 12 and the respective punching tools 10.
  • Each selector mechanism 14 includes a mounting plate 16, and an interposer l3, rocking lever 2% bell crank 22, and cushion ing lever 24 mounted on the face of the mounting plate 16. All these members are stamped from sheet metal to make them sufiiciently flat for the selector mechanism 14 to be readily accommodated within the thickness (in a direction perpendicular to the plane of FIG. IA) of the single punching tool operated thereby.
  • FIG. ID illustrates this by showing the way in which the assemblies of the interposers 18 and mounting plates 16 of each punching tool 10 are arranged along the length of the striker bar 12.
  • Each interposer 13 can be pivoted between one position wherein it is interposed between the striker bar 12 and its punching tool 16 to transmit the motion of the former to the latter, and another position (seen in FIG. IA) wherein it does not so transmit this motion.
  • the interposer 18 is pivotally nested within a recess 29a formed in the rocking lever 2% which rests atop the punching tool 19 and has its right-hand end pivotally connected by means of a pin 3%) to the mounting plate 16.
  • a tension spring 32 is connected between the left hand end of the rocking lever 20 and the interposer 18, to bias the latter for counterclockwise rotation toward a position wherein it is struck by the striker bar 12 to transmit the motion thereof to the punching tool 10.
  • FIG. IA shows the interpeser 18 in position to permit the striker bar 12 to drive the punching tool 16.
  • an armature arm 22b of the bell crank 22 is attracted upwardly, as indicated by arrow C, by a solenoid 46 which is accommodated within a cut-out 16a formed in the mounting plate 16 (see FIG. IA), and which has just been energized.
  • This rotates the bell crank 22 counterclockwise about its pivot pin 36 to move the latching arm 22a thereof out of latching engagement with the interposer tail 1811, thus permitting the upper part of the interposer 18 to rotate counterclockwise toward the striker bar 12 under the urging of the tension spring 32, as indicated by arrow D.
  • FIG. ID permits a ready comparison of interposers 18 which are in this position preparatory to actuating their respective punching tools 10, and other interposers 18 which remain in the punch-idling position.
  • the punching tool 10 then rides downwardly through a bore formed in a pair of upper and lower punching tool guides 59 and 52 respectively to drive a cutting surface 1th; at the lower end thereof through the body of a tabulating card T which has been inserted between upper and lower card guide plates 54 and 55 respectively, and between the upper and lower punching tool guides 50 and 52.
  • FIG. IC the striker bar 12 has risen again, as indicated by arrow F, and the punching tool is being extracted from the hole which it has just punched in the IA-C, extending perpendicularly to the plane of these figures and parallel to the row of punching tools 10.
  • the crossbar 64- is iorrned with a tongue 64a which projects into notch 10b formed in each of the punching tools 10;
  • Each such notch 1% has a large enough vertical dimension so that whenever the particular punching tool 10 is not being actuated the tongue 64a rides idly therein as the stripper bail 6i) oscillates vertically as indicated by arrows G of FIG. IA, H of FIG. IB, and I of FIG.

IA.
  • the tension spring 78 rotates the cushioning lever 24 against the stop 72 so that he hooked abutment 24b thereof protrudes into the return path of the latching arm 22a.
  • the latching arm 22a Upon its return, the latching arm 22a then strikes the; hooked abutment 24b and drives the cushioning-lever 24 back from the stop 72. In order to do this it must tense It will The hooked V the spring 73, which thus provides a cushioning action allowing the latching arm 22a to strike the stop 72 more gently so as not to rebound therefrom.

  • the carriage 100 is secured at either end to a pair of pillars 194 by means of bolts 1%.

  • FIG. IE it is seen that when the assembly of the pillars 104-, carriage 1G0, and striker bar 12 is driven downwardly through its punch-actuating stroke, the fiex-ure springs Hi8 bend in the manner illustrated, thus providing a suspension which allows these members the required freedom of vertical movement. Thereafter the flexure springs 198 spring back to the position of FIG. IC.
