Definitions

  • This invention relates to tabulator machines and more particularly to the means for printing alphabetical characters from the so-called spelling field of a card.
  • the perforated cards are first stacked in a magazine from which they are ejected seriatim 2 to a sensing box, in which the cards are temporarily held during translation, a condition corresponding to such translation being then set up in a stop basket preparatory to actuating the type sectors to the printing position.
  • the 25 sensed or translated card is fed to a receiving magazine and another card .is fed forward to be translated for another line of printing.
  • One object of this invention is to provide means whereby tabulator machines, provided with alphabet type sectors, may be run at a'much higher speed than has heretofore been deemed practical.
  • Another object of this invention is to provide a simplified mechanism for retracting the alphabet printing hammers a short distance, imme- 35 diately after they have struck the type, so that the type sectors may begin their return stroke immediately after printing.
  • Another object of this invention is to move auniversal alphabet sector restoring bail with sub- 40 stantially a simple harmonic motion, so that the said sectors may be restored by it with substantially the same type of motion.
  • Another object of this invention is to restore the printing hammers at the time that the speed of the universal bail is a minimum.
  • Another object of this invention is to speed up the printing hammers by reducing the distance through which the said printing hammers travel to strike a printing blow.
  • Another object of this invention is to restrain the alphabetical printing hammers during totaling operations.
  • Fig. 1 is a front to rear diagrammatic elevation, showing 2. Powers tabulator in which the invention is embodied.
  • Fig. 2 is an approximate full sized elevation of an alphabet printing sector in initial position.
  • Fig. 3 is a detail view showing the position of a hammer at the end of its percussive stroke.
  • Fig. 4 is a view corresponding to Fig. 3 after the hammer has had its momentum spent.
  • Fig. 5 is a cross sectional elevation showing the mechanism for operating the alphabet sector universal bar.
  • Fig. 6 is a rear view of the alphabet unit.
  • Fig. '7 is a diagrammatic view showing the mechanism for restraining the alphabetic hammers during the space and total strokes of a totaling cycle.
  • Fig. 8 is a face view of the type on a type carrier.
  • the invention is shown applied to that form of Powers tabulating machine disclosed inthe patent to William W. Lasker, No. 2,044,119, dated June 16, 1936.
  • the card hopper I'I corresponds to magazine II hereof, arm 2I to arm I3, feed rolls 81 and 88 to feed rolls I4, card stop 236 to card stop I6, main shaft to main shaft 28, eccentric I83 to eccentric I9, sensing pins I14 to sensing pins 2
  • a stack of pre-grouped perforated cards I0 is first inserted into the magazine II.
  • the cards are ejected seriatim from said magazine and indi-. vidually tabulated.
  • the cards are extracted from the stack by means of the usual picker knife I2 operatively connected to an arm I3 of the usual picker mechanism the cards being then engaged successively by pairs of feed rolls I 4 and I5 arranged to move the card rearwardly against an effectively positioned card stop I6 which holds the card stationary between the pin boxes which are indicated in general by the reference numerals l1 and I8 (Fig. 1). While the card is held in the sensing position, the lower, or sensing pin,
  • vbox I8 is moved upwardly by a mechanism including a link embracing an eccentric disk I9 secured to themain shaft 20.
  • the said main shaft is continuously rotated by a usual form of prime mover such as an electric motor, (not shown).
  • the shaft 28 makes one rotation for each card tabulated and such rotation of this shaft is designated a cycle.
  • the lower pin box i8 is provided with a plurality of rows of sensing pins 2
  • the card stop I6 is elevated and the now sensed card is fed onward by the pairs of skid rolls
  • the mechanism for printing alphabetic characters includes a number of pairs of arms which are journaled on the frame supported shaft 31 and are normally held in the relative positions shown in Fig. 2 by spring pressed catches 8
  • the arm 35 carries a plurality of usual spring restored plunger types 36; and is connected to arm 83 by means of a pin 84 fixed to arm 35 and a spring urged catch 8
  • are adapted to engage each other.
  • the members 35 and 83 tend to rotate relatively to each other because of the tensioned spring 88 connecting them, which spring also urges the latch 8
  • the member 35 is provided with an upwardly and rearwardly extending arm which is shaped to provide two hooks, one indicated at 8
  • Stops 85 control the positioning of stop sector 83. It has been described above that the differential stops 65 are positioned by a reciprocation of the sensing box
  • Each of the stops 85 is provided with a stud 1
  • Said slide 68 is mounted so as to have a sliding transverse movement on frame supported rods 81, 88.
  • the forward end of the bell crank lever 18 has pivoted thereto the zero stop 84; hence, when any differential stop 85 is elevated, its stud 1
  • any of the first eleven characters of the aiphabetare sensed one of the eleven stops 85 is elevated to determine the proper position of the type. If the twelfth character is sensed, disconnector 88 is elevated. The elevation of this element rocks catch 8
  • the universal bar 38 is carried at the lower ends of a pair of frames 48 pivoted on the supporting shaft 31. Said arms are pivotally connected through pins 45 fixed thereon to the links 44 extending rearwardly to pins 43 of the cranks 4
  • (Fig. 5) is fixed by some suitable means such as the rivets 41 to a long hubbed gear 48.
  • Each of the hubs of said gears is pinned to the shaft 42 so that the crank, gear and shaft rotate as a unit.
  • Each of the gears 48 meshes with a companion gear 54 pinned to the auxiliary main, sometimes called rotation, shaft 58.
  • a complete rotation of the shaft 58 correspondingly causes a complete rotation of the cranks 4
  • Shaft 58 is a rotation shaft which is connected through a pair of beveled gears 52 (Fig. 1) to the frame supported downwardly extending connecting shaft 53, the lower end of which terminates in one of a pair of similar beveled gears 5
  • the main shaft 28 rotates in the direction of the arrow shown in Fig. 1 and gears 52 are so located that shaft 58 rotates in the opposite direction but with the same speed of rotation.
  • spring pressed hammers which are journalled on a frame supported shaft 8 are provided.
  • the printing hammers 81 are normally restrained in cocked position by the spring pressed latches
  • Each of the latches I84 has pivoted near the midpoints thereof, a spring pressed interponent I03 which lies above the forwardly extending arm of its companion bell crank lever 98 which bell crank is loosely pivoted on the printing element frame supported shaft 99.
  • the bail I I9 (Figs. 2, 3, 4 and 7) is carried by a pair of arms fixed to the shaft II8. Also fixed to said shaft I I8 is an arm I to which is pivoted a link I2f extending downwardly to a pivot I- on cam I22 of the type usually used for engaging and disengaging totalizers which camis fixed to the main oscillatory shaft I23.
  • a pitman I28 is pivoted to the upper end of arm I29 (Fig. 1), which arm is fixed to shaft I23. Said pitman extends rearwardly to pin I21 which extends laterally from crank I26 fixed to the rotation shaft 50.
  • Each of the printing hammers 91 is provided with a forwardly extending finger II1 which lies by partially stretching the springs in the path of the rearwardly extending end of its associated spring pressed buffer arm 2. Just before the hammer 91 reaches the positioned type, as shown in Fig. 4 the associated finger II1 will contact the associated arm II2.
  • Each of the buffers H2 is loosely fastened on a printing unit supported shaft H3 and is held in its normal position shown in Figs. 2 and-4 by a spring II5 which is strong as compared to the relaxed strength of the printing hammer actuating springs I09. The printing hammers are released when the pins 43 of the cranks 4I have reached their approximate lower dead center position,
  • a slide I38 is associated with each order of the reading retaining pins 24. This slide I38 is spring pressed rearwardly by a device such as that shown in Fig. 19 of the cited Patent No. 2,044,119.
  • Slides I38 may be. pre-selected by positioning a manually settable interponent I380 between said slides and a universal bail, thereby controlling the functions of total control shaft I 39 through a pawl and ratchet mechanism which is actuated by a cam (such as 360, Fig. 2'? of the cited Patent No. 2,044,119) on main shaft 20.
  • a cam such as 360, Fig. 2'? of the cited Patent No. 2,044,119
  • slides I38 are move-d forwardly by the movement of any upper;-.or reading retaining, pin 24.
  • This motion of slides I38 causes the forward end thereof to contact interponent I380 which has been set in the process of preselecting the column in which the change-of-designation is to be made effective.
  • the motion of I 38 will move interponent I380 and bail I38I causing an oscillation of shaft I382 which shaft corresponds to shaft 336 (Fig. 10) of the cited Patent No. 2,044,119.
