Definitions
- This invention relates to a key and/or pattern card' operated punching machine for" effecting data perforations in record cards.
- the present invention is primarily for use in a punching machine for punching so-c'alled multideck record cards which are fed one by one from a supply hopper to and past a, row of punches, step by step as disclosed and claimed in our copendin'g applicationv Serial No. 61,662, filed November 23', 1948', now-Patent No. 2,566,931 issued September 4, I951. Provision is made in this punching machine to unch key-set data in a first deck as the card passes the row 6f punches and, if data is to be unched in a second deck, the card is then retracted and fed past the row of p'un'ches a second time to receive data in the second deck.
- the card is retracted for a second time and then fed past the punches to receive data in the third deck.
- the card is not shifted along its lesser dimension to punch the plurality of decks and a bank ofpu'nches extending across three decks, here twenty-one punches, is employed.
- the principal object of the present invention is to provide an improved keyboard incorporatingtherein coding devices,v whereby a key representing an alphabetic or numeric character or a symbol will establish circuit connections to efiect punching. of holes in accordance with a 7-hole combination code.
- Fig. l is a plan View of the alphahetic keyboard of this invention.
- Fig. 2 is a plan view ofithe' alphabetic keyboard with the casing partly broken awayto show the interior mechanism.
- Fig. 3 is an emarged detail of part" of the key operated selecting mechanism.
- FIG. 4 shows the arts-in Fi 3 in anotherpositi'on".
- Fig. 5 is a section taken on line 5&5 ofFig'. c;
- Fig. 6 is a section taken on line 6-6 of Fig.2;
- Fig. 7- is a section taken on line 1--Tof"Fi'g. 6 showing. the combination selecting mechanism.
- Fig. 8 is a view of the card and-code perforations.
- the card which is used in conjunction with the keyboard of this invention is shown in Fig. 8 where it is shown provided with five decks designated A, B, C, D and E, each of which has seven horizontal rows of punching positions designated X, Y, Z, 0, 1, 3, 5.
- the card is further provided with sixty verticalcolums so that it will be seen provision is made for recording three hundred characters on this card. In the great majority of commercial applications, three decks are generally sufficient to'record necessary data, as three decks of sixty columns each provide one hundred and eighty character recording positions.
- the record card is designed to cooperate with a row of punches extending across the three lower decks A, B and C spaced to correspond to the punching positions on the card, that is, there are twenty-one punches.
- the punching mechanism is described in further detail in the above mentioned copendin'g' application.
- the card is first m'ovedpast these punches and the set of seven punches related to a selected one of the three decks A,-B or'C is oper'ated to punch data in this selected deck.
- the card is then re tracted, preferably automatically, and moved past the punches asecondtime" during which the group of seven punches related to either of the other two deck-s are operated to punch the desired data in its related deck, and finally after a second retraction the" card is moved past the punches a third time, during which the set of punches related to the third deck is operated.
- a master or pattern card is inserted in asuita-ble reading station and this card is provided with perforations which are to-be duplicated in each of the cards moved past the row of punches;
- the arrangement is such that all data to'be' duplicated is punched in the blank card during the first movement thereof past the row of punches.
- This firstmovement is termed a first pass.
- 'Ihe'second' movement is termed the second pass, and similarly the third movement is called the third pass; so that during the first passof'lthecard all-data obtained as a' result of control by the pattern card is punched regardless of the-deck in which it occurs.
- the three card fields designated Duplicate" are punched during the first .pass.
- the cards are fed through the punching machine in a separate operation but inverted to feed face down, and the set of punches in each deck is operated invertedly, that is, the X punch is operated to record in the position, the Y punch is operated to record in the 3 position, and the Z punch is operated to record in the 1 position and so on.
- duplicating this is accomplished by also inverting the pattern card.
- the card of Fig. 8 shows variable data punched in the fields labeled Key Punch under control of manually operated keys l0 (Fig. 2) and. common data punched in fields labeled Duplicate under control of the pattern card (not shown), which latter contains perforations in its corresponding fields.
- the fields labeled Skip are left blank and automatically passed.
- Alphabetic keyboard The keyboard which comprises this invention is shown in Figs. 1 and 2, with the keys in arranged in a conventional manner for operation by a typist. Additional keys designated REL, DUP, SKIP, 5, X, Y and Z are provided in the lower right hand corner with the four last named keys shaded to distinguish them from similarly identified keys in the conventional group.
- each key It is suitably supported for vertical movement and is normally biased upwardly by a spring Ii.
- key 50 When depressed, key 50 will rock a bell crank lever 12 to draw a connected link l3 toward the left.
- the space key a has a similar bell crank connection to a link I3, so that all of the keys when operated will actuate a related link l3 with the exception 4 of the Duplicate key H) which closes a pair of contacts (not shown) when depressed.
- Each link l3 has a right angle extension
- This latch has a l
- the latch Ii serves to hold slide 2
- are all provided with a series of notches 24 into which the fingers 25 of a set of ten plates 26 extend.
- Each plate is integral with a rod 21 (Fig. '7) mounted for oscillation in end plates 28.
- a rod 21 (Fig. '7) mounted for oscillation in end plates 28.
- the rods 21 are labeled 5, 3, 1, 0, Z, Y, X, KB, SKIP and REL and the fingers 25 are arranged combinationally so that, when a particular character key is operated, the rods 2! corresponding to the combination for that key, as set forth in the table above, will be rocked.
- the KB (key bail) rod 2! has a finger 25 in all positions except Shift, so that when any slide 2
- the Skip and Releasekeys rock separate rods 2! similarly identified.
- has pivoted at 20 and adjacent to its latch 11 a.
- spring pressed lever 29 which, when the slide is lowered, will assume the position of Fig. 4 where its upper extremity extends slightly above the left edge of notch 16.
- This lever is to guard against an inadvertent repeat operation where the operator may hold the key depressed in such a position that, when latch I! restores upwardly, it may be caught by extension l5 and held to the left.
- Lever 29 prevents this by elevating extension l5, if it is not in its fully restored position, and maintaining it out of the notch
- the latches H are interlocked by the well known type of interlocking disks 38 indicated in Figs. 2, 3 and 4 which allow only one latch to operate at a time with the exception of the ones related to the Shift keys, which are not interlocked.
- Each plate 26 and related rod 21 has a single, rearwardly extending finger 35 and these are arranged in two vertical rows near the extremities of the rods (Figs. 2 and 6) with alternate fingers at one end for more convenient spacing.
- Each finger 35 extends beneath an insulated contact blade 35 (Fig. normally out of contact with a common conductor 3'! so that, when a rod is rocked, the related finger 35 will shift its blade 36 into contact with common conductor 31. Accordingly, the contacts 36, 31 are closed in combinations corresponding to the combinational arrangement of fingers 25 in Fig. 7 and in the table above, and these contacts will close circuits to effect punching operations.
