snmznr 4 2 62 i 5 I INVENTOR r\ um mm 1 Robert/ Murray ATTORNEYS PATENTEU JAN 5 I971 SHEET '4 BF 4 4 m m 4 O I20 HO Ill ATTORNEYS Robert H Murray M Wi W SCORING DEVICE FOR PUNCHING AND REMOVING CHIPS FROM COMPUTER PUNCH CARDS HISTORICAL BACKGROUND For many years, computer punch cards' have been available which are scored in such a manner as to provide a plurality of rows of rectangles thereon which may or may not have identifying indicia. These cards are used in such amanner that the rectangles form chips of cardboard, or the like once they have been punched out along the score'lines. One of the problems of present day equipment for removing the rectangular chips is that they tend to hinge on side or the other and not break free from the card. Thus, when the cards are stacked, some of the chips which have; not been completely removed, because of the hinge, tend to return to the hole from which they were struck. It is quite obvious, that someone endeavoring to read the information which has been placed on the card, could well be in error since they might not observe thatone of the rectangular chips though punched, has not been punched completely out.

Inadequate punching equipment has caused numerous errors and frequent backchecking to determine whether or not there are any chips which are hinged so that they can be removed prior to scoringqFor the most part, machines which have been manufactured with the intent of completely removing the chips. are expensiveand not foolproof.

Elaborate and costly means have beendeveloped to insure removalof the chips in order to eliminate error. Frequently,

check must be done visually and the chips removed by hand.

OBJECTS AND SUMMARY It is therefore an object'of this invention to provide a machine or device for punching and removing chips from computer punch cards which is simple and inexpensive to manufacture.

Another object of this invention is to provide a scoring device for removing, chips from computer punch cards by manual means.

FIGS. 1 THROUGH 3 In FIG. 1, the scoring device includes a card holder generally shown at H. A card C as best shown in FIG. 2, is fed into a slot 10 in the rear of the card holder H. The slot is formed by upper holding or restricting

means

12 and 14 and lower support means 16 and 18.

Sidewalls

20 and 22 position the upper holding means 12 and 14 and lower support means 16 and 18. An opening or slot 24 is formed between the lower support means 16 and 18. Mounted to project slightly into the slot or opening 24 is a feed roller 26 having an external manipulating knob 28 as best illustrated in FIG. 1. The feed roller 26 preferably is of resilient material and preferably is knurled or corrugated lengthwise. Mounted beneath the roller 26 is a chip receptacle 30.

The upper holding or restricting means 12 is provided with a bore 32 (FIG. 2) which matches with an opening 34 (FIG. I) for holding a punch stylus 36 which is held captive to the sidewall 22 by means ofa chain or the like 38.

The upper holding or restricting means 14 is provided with a series of parallel coextensive slots 40. In FIG. 2. it will be noted that the rear face of the slot 42 is positioned above the feed roller 26 andslightly forward of the axis of the feed roller The front wall 44 of the slot 40 extends beyond the outer periphery of the roller 26.

Mounted in advance of the upper restricting means 12 is an indexing roller 46having various indicia thereon for identifying the parallel coextensive slots 40 and thus for determining different informational series which might. be. selected forscoring the card'C. A knob 48 is provided for rotating. the indexing roller 46 to present different ind'icia depending upon the type questions which are to be answered and scored on the card C. l V

Adjacent the slots 40 is a visual aligning slot or transparent guide 50 which permits the operator of the card holder H" to position the card initially. within the holder H so that the scored rectangular portions of the card C will be positioned properly beneath the openings or slots 40 whereby the punch stylus 36 will operate directly to remove the chips 52 from the card C.

In FIG. 3, it will be noted that the stylus 36 includes a punch 54 which is spring biased by a spring 56.

OPERATION It will now be obvious that when the'punch' 54 of the stylus 36 is fed into one of the slots 40, and the card C has been posi- 1 tioned in such a manner that the rectangularchips are directly aligned with the slot 40, the punch 54 will engage the chip 52- and force it against the resilient roller 26. Since the pressure of the stylus will be slightly off centerof the roller 26, the roller will rotate in a clockwise direction as'illustrated in FIG. 3. In doing so, the chip 52 will be clamped'between the roller 26 and the punch 54 and will be stripped from the card C. The rotation of the roller 26 will also cause the stylus 36 to be moved forwardly in the slot 40 toward the front wall 44 and in so doing will advance the card C the exact distance necessary to present a new scored rectangular chip 52 for a new punching operation. The spring 56 allows the punch 54 to recoil slightly thereby permitting a constant pressure on the roller 26 without severely damaging the roller 26 to thus provide long life for the roller 26.

As the chips are stripped from the card C,'they drop into the chip receptacle 30 which is removable for disposing of the chips which have collected therein. It is to be noted that the punch 54 can only travel downwardly into the slots 40 up to the barrel portion of the punch stylus36. Thus the stylus 36 is limited both in downward travel by the width of the slot 40 and in forward travel by the front wall 44 of the slot 40.

FIGS. 4 AND FIGS. 4 and 5 show a slightly different feeding mechanism which can be utilized within the card holder. The upper holding and restraining means 12 and I4 are identical to the structure illustrated in FIGS. 1 through 3. However, a lower support means 58 comprises a piece Of flat sheet material from which has been struck downwardly beneath the slots 40 a series of ramps 60. The ramps 60 may be grooved as illustrated. In effect, the ramps 60 substitute for the roller 26 in FIGS. 1 through 3. When the stylus 36 is inserted into one of the slots 40, it will engage aninserted card in the area of the rectangular chip and force the same against the ramp 60 so that the chip will be clamped between one of theramps 60 and the punch. As the stylus is forced into the slot 40, it is also carnmed downwardly on the ramp 60 thereby stripping the chip from the card and at the same time advancing the card to the next succeeding scored chip area for a subsequent punching operation. The ramps 60 may be resilient to flex and take up some of the shock of the stylus. The punch 54 of the stylus 36 need not be spring biased in view of the flexing of the ramps 60.

FIGS. 6 AND 7 FIGS. 6 and 7 illustrate yet another modification of the invention in which the stylus is eliminated and a series of fingers 62 which are resilient and flexible are-each provided with a punch 64 which is mounted to pivot in an opening 66 in the finger 62. The punches are providediwith naillike heads 68 which prevent the punches 64 from dropping through. the openings 66.

It will be noted in FIG. 6 that upon' depression of the finger 62 tothe dotted line position, the:punchfiglgwill pivot forwardly and downwardly on the roller-26-to-both strip the chip 52 from the card C and advance'the card for the nextrchip removing operation. ",{Ii

FIGS. 8, 9, AND10 .J FIGS. 8, 9, and 10 illustrate. yet :anpih fb i mechanism in which a series of flexible fingers- 70. replace the fingers 62 of FIGS. 6and 7.,The fingers 70.are providedwith, punches 72..Buttons 74 permit depression otZthe spring fingers- 70 which are formed from a single sheet of material-sothat,

they are all interconnected electrically to a single electrical connection 76 which is tied in to a lead wire It is to be noted that the punches 72 include a stop tab 80. .Mounted in the walls of the card holder is a feed. lever 82having a cam surface 84 and a feeddog 86., A spring 88 biases the feed lever forwardly and is connected to a wall 20 of the ,card holder H.

A locking bar 90-extends between a pairof thefeed levers 82 as best illustrated in FIG. 10.

Mounted just behind the buttons 74 and above the fingers 70 is a rocking bar 92. The rocking bar. is journaled-in the sidewalls of the cardholder H. A rocking arm '94 is secured to the rocking bar 92 and extends forwardly of the rockingbar 92 and beneath the fingers 70. A feed lever arm.96 is also connected to the. rocking barv 92 and extends rearwardly of I the rocking bar 92 and beneath the feed;fingers-70 and connects to the feed levers 82 on either side of the cardholder H. A series of contact conductors 98 are positioned below thestop tabs 80 and are provided with a series of leads 100 which, junction in a multiple outlet 102 as does also the leadwire 7,8.

OPERATION OF FIGS. s rHR UoH 10 It will now be obvious that upon the depression of the buttons 74 one of the spring fingers 70 will bedepressed and the punch 72 will enter the slot 40 for the purposeof striking out one of the chips of a card (not shown).- As the fingeris' descends, and the feed lever 82 reciprocates rearwardly, the

locking bar 90 mounted between the feed levers 82, will move rearwardly and beneath the stop tabs of the punches 72 which have not been depressed thereby insuring that these punches will not be depressed while the other punch is depressed. It will be noted that the punch which is depressed as illustrated in FIG. 10, in its downward travel, causes the tab 80 which also doubles as anelectrical contact, to engage the electrical contact 98 completing a circuit between the fingers 70, the electrical connection 76, the lead wire'78, and withthe lead 100. The outlet 102 is plugged into an indicating device (not shown) which will indicate which of the buttons 74 have been depressed and automatically score electrically in a unit (not shown). Upon release of the button 74, the feed. dog 86 will engage one of the feed holes or slots in the card for advancing the card to the next position for subsequent punching operation. The spring 88 will cause retraction of the feed levers 82 upon release of the button 74.

FIGS. 11 THROUGH 14 FIGS. 11 through 14 Show a modified type of punch mechanism in which the feed of the card, is prior to the punch stroke rather than after the punch stroke as illustrated in the

sidewalls

20 and 22. The rocking bar includes a locking arm 112 and a cam arm 114. Depending from the rocking bar 110 are rocking levers 116 which engage the card feed yoke member 118. The card feed yoke member 118 includes pawl feed fingers 120. The punch arms 104 include cam surfaces 122. The card'feed yoke 118 is spring biased rearwardly by means of a spring 124. In operation, upon depression of one of the buttons 106, the cam surface 122 operates against the cam arm 114 of the rocking bar 110, to cam it forwardly and at the same time to cause the locking arm 112 to move beneath the projecting fingers 126 of the punch arms 104. When the rocking bar is rocked, the rocking levers 1 16 move forwardly engaging the card feed yoke 118 causingthe pawl fingers 120 to engage in openings previously provided in special cards so as to index the cards forwardly to the next station. Upon further depression of the punch 106, the rihips are forced out of the card by means of one of the punche 108. The action of spring 124 returns the rocking bar to its original position so that the cam arm 114 engages in the cam S] t 128 upon release of the button 106.

FIG. To FlU. s

FIG. 15 illustrates still another modification of the invention in which aslotted feed roll 130 as best illustrated in FIG. 16 is provided. The feed roll 130 is provided with a series of annular friction feed rings 132. Slots 134 are provided in the rotor at spaced intervals for permission of entry of the punches 136. The punches 136, which are mounted on arms 138, force the chips into the slots 134 thereby stripping them from the cards which have been inserted into themechanism in a manner heretofore described.

The friction feed rings engage the undersurface of the cards to advance the same for positioning beneath the punches 136. When the 'chip'has been forced by'the punch into the slots 134, the slots provide a-gripping action and maintain the chips within the slots until stripped therefromby means of stripping fingers 140 which extend into the slots and force the chips therefrom and into the chip receptacle provided. The punches 136 fold the chips in U-shapes between the walls of the slots 134 to cause them to be frictionally engaged thereby due to the spring action of the folded chip. 1

The punch arms 138 are provided with a slot 142 which receives a rivet 144 connected to the punch 136. The punch 136 is biased to the rear of the slot 142 by means of a spring 146 attached to the rivet 144. In operation, one of the buttons 148 of the punches 136 is depressed. As the punch 136 enters into the slot 134 of the roller 130, the punch 136 moves forwardly as the rivet 144 travels forwardly in the slot 142 against the spring 146. Upon release of the button 148, the rivet returns to the rear of the slot bringing with it the punch 136. This action permits the punch 136 to act as the means for feeding and indexing the card to the next succeeding position for subsequent operation.

FIG. 19 illustrates how any one of the card holders H heretofore described, can be equipped with a second punch mechanism generally indicated at 150. This punch mechanism is located in the bottom of the card holder and includes a spring identifying punch arm 152 with a series of punches 154 mounted thereon. A slot 156 is provided in the card holder H for receiving a card. A stop 158 limits the insertion of the card into the slot 156. Upon insertion of a card into the slot 156, the punch arm 152 is depressed upwardly causing the series of punches 154 to punch the identifying information into the card. The card is backed by a sponge or resilient backing material 160 against which the series of punches force the chips so that they will be stripped from the card.

While theinvention has been described, it will be un derstood that it is capable of further modifications, and this application is intended to cover any variations, uses or adaptations of the invention following in general the principles of the invention and including such departures from the present disclosure as come within known or customary practice in the art to which the invention pertains, and as may be applied to the essential features hereinbefore set forth and as fall within the scope of the invention or the limits'of the appended claims.
