  • Fig. 2 shows the covers 2 and the lids 3 swung outwardly so as to expose the working parts of the machine. Suitable bosses are provided for limiting the inward movement of the lids 3, and each of the covers 2 are provided with a usual form of spring catch 4 which cooperates with holes in the main frame of the machine to retain the covers in the position shown in Fig. 1.
  • One of the covers is provided with a spring-pressed lever 5 for either starting or stopping the machine.
  • the operation of the covers 2 may be likened to that of an ordinary Boston bag or pocket-book.
  • Located on the lid 3 is the usual angle plate for justifying the cards prior to placing them in the magazine 6.
  • the frame of the machine is a usual form of skeletonized box comprising a base or bottom, sides, and ends which support the various studs, bearings for shafts, anchorages for springs, etc.
  • Fixed to the base is a housing forthe worm drive and guiding studs or parts, for the reciprocating pin box assembly, and for the reciprocating printing platen.
  • the cards to be interpreted are stacked and weighted in the magazine 6 (Fig. 4) and are fed successively from the; bottom of the stack by a power reciprocated picker 1; thence through a usual form of adjustable throat opening; thence to'the first of a series of pairs of continuouslyrotating feed rolls 8; thence into the sensing chamber 9 which consists of a pair of matched perforated plates having their perforations at positions corresponding to every possible perforation in a card.-
  • the lower matched plate of the sensing chamber 9 lies slightly above the sensing pins of the reciprocatory sensing box 10 when said box is in its lowest position; said box also carries the. card stop l2.
  • a pair of skid rolls 8' (Fig. 6) for feeding a card after it has left the first pair of feed rolls 8.
  • the sensing box I3 (Fig. 4) rises so that the card stop I2 is in a path of the card before it has reached the position for sensing, but the pins of the pin box do not pass the top plane of the lower matched plate until after the card has reached the card stop i2 and universal bar 30 has reached its rearmost position (to the left as viewed in Fig. 3, or to the right as viewed in Fig. 8).
  • a pair of skid rolls B' similar to those used in the sensing box for feeding the card against the pre-positioned card stops 20 and also out of the printing chamber, when the said card stops are withdrawn, thence to the last pair of feed rolls 8 which eject the printed interpreted card into a suitably locatedstorage magazine.
  • ! and the operation of the ink ribbon mechanism are controlled from the main shaft 22.
  • the main shaft 22 is driven from a suitably located electric motor (indicated by a conventional diagram, Fig. 3) through a belt, worm and worm wheel, the latter of which is attached near the center of the main shaft 22 as is best shown in Fig. 17.
  • the picker eccentric 23 Adiacent the housingof the worm drive is attached the picker eccentric 23 (see also Figs. 9 and 17) which causes the picker 1 tobe reciprocated through the medium of a link surrounding said eccentric and a motion multiplying shaft and arm mechanism 24 (Fig. 4) which is directly connected by a short link to the picker 1.
  • the picker 1 makes a complete reciprocation for each rotation of the main shaft 22.
  • Adjacent the worm drive housing is a cam 62 (see also Fig. 1'!) for governing the card stop for the printing mechanism.
  • Said cam is adapted to oscillate an arm fixed to a sleeve pivoted on an intermediate shaft. Two arms fixed to said sleeve extend rearwardly to support a bail on which is pivoted a pair of symmetrically arranged spring urged card stops 20 (see Figs. 7 and 18 and 19) which are projected and withdrawn at the proper times from the path of the card as it travels through the printing chamber.
  • the card stops 20 of the printing mechanism are resiliently urged rearwardly by spring plungers contained in the massive part of the printing platen block I! so that they will normally take a position corresponding to an extreme rearward one, which corresponds to the lowest possible print position on the card.
  • each card stop 20 is provided with an extended heel near its pivot point.
  • the card stops 28 can therefore be shoved against their springs by an adjustable universal bail 49 to regulate or determine the position on the card in the printing chamber which will receive the imprint.
  • the rearwardly extending stem of the bail 49 is provided with slotted openings through which pass clamping screws for adjusting the said bail. This adjustment is desirable for locating the printing of the interpretation on a part of the card where there are no perforations. However, the majority of cards have no perforations along the 12 row or along the 12 and 4 rows, hence neatness of the interpreted card suggests a lowering of the printing line, therefore the described adjusting mechanism is ineluded.
  • each shaft 27 Fixed to each shaft 27 is a series of gears for driving-the lower of the pairs of feed rolls 8.
  • the first of the pairs of feed rolls 8 are positively geared together as shown in Fig. 3, but the upperrolls are usually driven by frictional engagement with the lower rolls or through the card as is shown in Fig. 13.
  • Each shaft 21 drives the lower of the pair of skid rolls 8 in the sensing chamber and the pair of skid rolls 8 in the printing chamber in exactly the same manner as the lower of the pairs of rolls 8.
  • the upper skid rolls 8 are frictionally driven as above described.
  • the frictio-nally driven rolls are mounted on spring urged frames, or levers as the case may be, as is the usual practice in perforated card controlled mechanisms.
  • each gear 26 Adjacent each gear 26 is a lobe shaped cam 28.
  • Said cam 28 drives the reciprocating universal bar 30 (Figs. 3, 5, and 17) through a pair of links 3i which in.turn are pivoted at the upper end of the frame supported bell cranks 32, whose lower ends carry rollers riding on the peripheries of said cams 28.
  • each link 3! is provided with a simple form of springpressed latch fitting into grooves on the universal bar 30 so that a manipulation similar to that of opening a cabinet door is suflicient to release the main restoring bar 30. This construction is desirable for, at times, it is necessary to remove, substitute, or replace one or more devices such as those illustrated in Figs.
  • each cam 28 (see Figs. 8 and 17) carries a roller which rocks a frame-supported, spring-urged lever 33 for each rotation of the main shaft 22.
  • the upper ends of said levers 33 are joined by a bar which is universal to the shorter arms of all of the bell cranks 39, hence rocking of levers 33 results in rocking bell cranks 39 and therefore,
  • a pair of sensing box cams I8, (Figs. 12, 1'7) on which ride anti-friction rolls carried by a pair of long arms l9 (Figs. 18 and 19) pivoted near the rear of the machine on frame supported studs.
  • the forward ends of said arms underlie studs fixed to the frame of the sensing box l0, (Fig. 6) hence said cams 18 rock said arms is to operate the sensing box during each rotation of the main shafts.
  • a pair of platen operating earns 55 Adjacent the cams i8 is a pair of platen operating earns 55 (Figs. 4, 11, and 1'7) each rock a platen operating lever 53 to elevate the respective sides of the platen block H.
  • the levers 53 are pivoted to studs integral with the platen block i7 and their extreme rear ends are pivoted to the upper ends of a pair of toggle links 538, whose lower arms are fixed to the shaft 52.
  • a record presence sensing mechanism causes said toggles to be broken so that the platen block ll, although it started its upward excursion, is permitted to drop and remains in its lower-most position during an operation of the main shaft, if the said main shaft is kept in operation by holding lever 5 depressed.
  • the frame of the sensing box i ii and the platen block I! are mounted on a pair of stout hollow posts (see Figs. 6 and 7)which are fixed to the base of the machine. These posts accurately guide these parts'in their reciprocatory movements so as to prevent a tendency to rock sidewise when sensing cards with a preponderance of perforations near one edge or when printing interpretations of alphabetic codes or -eolumn numerals.
  • Extending through the center of each hollow post is a rod fixed to the respective reciprocating frames.
  • the lower end of each or said rods is surrounded by a spring, which in turn is held in place by a nut.-
  • These springs tend to hold the sensing box l0 and the. platen block ll in their lowermost positions, and thus hold arms i9 and 53 in engagement with their respective operating cams.
  • the card stop It is mounted on the sensing box Hi. It, therefore. follows that the movements of the latter closely simulate that used for the pin box of the familiar Power tabulator (see Powers Patent 1,245,502).
  • the card stop 20 for the printing chamber is operated by a separate cam 62 shown in Figs. 10, 1'7, and 19.
  • the cam 52 rocks its cooperating lever which is fixed to a sleeve surrounding the pivot shaft of the arms 53.
  • the said sleeve carries an additional rearwardly extending arm to which is pivoted a siidable card stop 29 as Well as the rearward extension of the arm cooperating with cam 62 as is clearly shown in F gs. 18 and 19.
  • a ret-ractor cam 63 Adjacent one of the earns 28 is a ret-ractor cam 63 (see Figs. 2, 3, and 1'7) which, at times, operates a spring pressed lever (carried by the pivot of a bell crank 32); thence an adjustable link connected to a bell crank 84 attached to a frame supported retractor shaft, thence a retractor ball 65 which is universal to all the spring pressed slides I5. (See Fig. 4).
  • cam 43 is adapted to shift all of the locking slides 15, and, therefore, release all pins M which are elevated.
  • the upper end of bell crank 44 is provided with a fin er piece for manually releasing the pins I 4 if the occasion so requires.
  • a piniixed to cam 43 (Fig.
  • a ribbon feed cam 56 Adjacent the other cam 28 is a ribbon feed cam 56 which operates a boomerang shaped-lever (carried by the pivot of bell crank 32) whose forward end is connected by a link 51 (Figs. 5, 6, 17 and 21) to an arm' fixed to the operating shaft 55 of the ribbon feed mechanism. Near each ofthe ends of the shaft 58 is a fixed arm, each of which carries a spring urged saw-toothed actuating rack 59 for the ribbon spool ratchets for feeding the inking ribbon 60.
  • the ribbon reverse mechanism will be described under a separate heading.
  • straight or 45 column code utilizes one perforation in each column to indicate a single digit of the recorded number
  • perforations at the top of the card indicating the number 12, perforations at the second position indicating the number 11", perforations at the rations at the fourth level or position indicating the digit 1, and so on to the bottom of the card.
  • Alphabetic codes ters-are ones of comparatively infrequent occurrence-and hence the context will clearly indicate the character intended. Indeed an arbitrary sign such as may be used instead of any of these letters.
  • Combination or 90-.colum n code Fig. 31 shows the perforations according to the combination or 90 column code in which the customary card is divided into upper and lower fields. Half of each column of the older 45 column code system is utilized for all ten digits by means of a system of single and double perforations, the even numbered digits being indicated by two perforations.
  • the first or 45-column numeric code is transformed into a mechanical code by elevating a single stop at a position corresponding to the location of the perforations in the card.
  • the familiar Powers sensing box has always been able to interpret thiscode,
  • the specific means used in the present instance is best shown in Fig. 16, and consists of a series of slidable stops 35, any one of which may be elevated and temporarily retained in the path of a spring urged measuring bar 36, which is connected through toothed gearing to the type wheel 31; Obviously 11 and 12 stops 35 may or may not be used, nevertheless they are usually provided for the contingency of printing an interpretation of British or English currency.
  • the second, or alphabet code is interpreted in a similar manner for the first half of the alphabet.
  • the spring urged measuring element 36 is limited by a raised stop 35 in the path of the pawl 38 pivoted to element 36.
  • the 12 stop 35 is raised as well as one other.
  • the 12 stop elevates the pawl 38 so that theextreme end of element 36 abuts against the positioned stop, thus permitting an excess of movement equivalent toabout half the pitch of the stops 35.
  • the structure of Fig. 14 is shown in its position of full travel. Under normal operating conditions, the member 36 is drawn to the extreme right by the-bail member of Figs. 2, 3, 5, 8, 19 and 26.
  • the member 36 will advance to a given point until the end of the member 38 contacts with the stop to position the wheel 31 for the printing of a given letter. If. however, the stop 35 numbered 12 is also. raised, the swinging member 38 is elevated, allowing the member 36 to advance a half pitch step further, thereby bringing the next adjacent character on the Wheel 31 into printing position.
  • the type wheel 31 is driven as before. Obviously the characters thereon are arranged with the second half of the alphabet interspersed with the first half. Fig. 28.) Certain rarely used or strikingly similar characters are combined, for example 0 and Q; U and V; X and Z, as is indicated in Figs. 29, 30, 31, 32 and 33; The last two columns will be explained at the end of the next paragraph for I it is really a combination of the described alphabetic code and the 90-column numerical code.
  • the third and fourth, or 90-column codes are interpreted in a manner analogous to that used for the last half of the alphabet, except that the provision of the half-pitch movement is effected by the particular arrangement of the stops 35. (See Figs. 8, l5, and 25.) All the odd digits are interpreted in exactly the manner described for the first code by the positioning of a single stop 35. The even digits are interspersed with the odds, therefore, an increase in movement of a hat stop pitch will sufiice to interpret them. 'I'ne extra movement is attained by elevating either the 3 or the 9 stop, or both. Each of these stops is arranged with a trapezoidal projection, (see Fig. 25) whose narrow side normally rests against a fixed pin. but when such stop is raised the corresponding spring urged measuring member 35 will travel an additional (See
