Definitions

  • This invention relates to improvements in printing and paper feeding mechanisms for computing or like machines and is shown as applied to the well known Powers tabulator mechanism of the type shown in U. S. Letters Patent to Powers #1,236,481, August 14, 1917, and including an automatic total taking mechanism such'as disclosed in U. S. Letters Patent to Lasker #1,376,555, May 3, 1921.
  • the novel features of the invention are not limited to embodiment in this type of machine or to the total taking-mechanism shown in these patents.
  • An object of this invention is the provision of automatic mechanism for feeding the paper variable distances after the total has been printed during a total taking operation, to present the first line of a new form or section of the paper to the printing line to receive the imprint of the first item of a new series of items, the mechanism operating to perform this function regardless of the number of items making up the total which are confined within the length of a single form or section.
  • a further object of my invention is to provide means for automatically effecting said variable feed of the paper in the event that the number of items on one form. exceed the length thereof and have to be carried over onto the next succeeding form.
  • Another object is the provision of adjustable or shiftable means for controlling the single or double line spacing of paper and for variably spacing the paper automatically after the impression during a total taking operation.
  • variable paper feeding means which can be manually thrown out of operation for any desired period as in cases where the items are printed on a plain strip of paper.
  • variable line spacing mechanism under control of printing and non-printing mechanism so that in nonlisting operations the total alone will be printed on the paper or the individual forms or sections and the paper automatically advanced to position the next form to receive the next total impression.

  • the forward lower side of the lever 53 is provided with a short arm 61 (Fig. 5) for engagement with a projection 68 on a bar 69 to limit the return movement of the lever 53 and thus determine the extent of the throw of the pawl 52 to feed the platen and paper a single line space only.

  • blocking means comprising a lateral flange or stop 80 (Figs. 1, 7 and 8) on a slide 8
  • the flange 86' will block the movement of a lever 84 connected by link 85 to the three armed lever 5! and thereby prevent retractlng movement of the feed pawl 52 from its actuated position, but this block will be removed and the paper feed mechanism rendered operative whenever the hammer lock is set to allow printing.
  • thevpush button 46 when thevpush button 46 is moved inward, it positions the ball 35 as hereinbefore described to permit item printing and by the actuation of the shaft 36, crank arm 83 and link 82, lowers the flange 86 out of the path of the lever 84, permitting this lever to rock against a stop 81 on a slide 88 which permits the three armed lever 51 to rock sumciently far to retract the pawl 52 for double line spacing movement.
  • the slide 88 has the stud 16 before referred to connected thereto so that this slide will be lowered by the arm TI to move the stop 81 out of the path of the lever 84 whenever the total control shaft 43 is rocked clockwise from the position shown in Fig. 8.

  • variable feeding mechanism may be disabled by throwing the pawl 95 (Fig. 5) to the right against a stud 99 on the arm 9
  • the effect of thus shifting the pawl 95 to and maintaining it in ineffective position is to render the variable feed mechanism inoperative without, however, interfering with the operation of the link 56, and the line spacing lever 53 controlled thereby, for effecting single and double line spacing, as hereinbefore described.
  • a manipulative three arm lever pivoted at (Fig. 4) is provided to engage a stud
  • paper is inserted and adjusted to the first line space of the first form.
  • Various information may be printed under headings as indicated. Following each listing operation the paper is fed a single line space or a double line space accordingly as it is controlled by the position of the bar 69.
  • the items are listed in succession and the maximum number of items on a form may vary in accordance with the predetermined construction of the variable line spacing mechanism and the length of the forms. After any variable number of items have been listed, a total card follows a space card, or the well known total designation control mechanism (not shown), initiates a total taking operation. This results in rocking the total shaft 43 clockwise from the position shown in Fig. 1.
  • the pawl 95 When the pawl 95 is in operation advancing the paper to the head of the next form the pawl 52 makes its motion of a double line space, but inefiectively, because the platen is then turned by the pawl 95 which, acting through the pinion 96 of relatively small diameter, causes the ratchet wheel 5
  • the variable line space pawl 95 is retracted a distance slightly greater than the length of a ratchet tooth on the ratchet disk 94, such retraction being permitted by the withdrawal of the limiting stop 81.
  • the pawl On the return stroke of the shaft ID on the total printing cycle, the pawl It is advanced and picks up the ratchet tooth over which it has been retracted and moves it into the position shown in Fig. 5, thereby feeding the work sheet to brins the first line of the next form into printing position.
  • the pawl 95 is given a predetermined uniform feeding stroke at each total printing operation, sufficient to advance the paper a distance equal to the length of a form. Howey during listing operations the ratchet wheel M has been advanced step by step relatively to the pawl Ii by the pawl 52 through the gears 93. I. a distance depending upon the number of items listed. Then when the pawl 95 is given its operating stroke after the total printing operation, a portion of the predetermined movement of the ratchet 84 has already occurred and the pawl II will pick up the corresponding ratchet tooth where it finds it and will complete the advance of the ratchet to the position shown in Fig.
  • the link 56 reciprocates at each printing cycle a distance limited by the stop ll.
  • Each such reciprocation produces a reciprocation of each of the pawls 52 and Ii, the former line spacing the platen and paper as above described.
  • This limited reciprocation of the pawl i is ordinarily an idle one, because the pawl is not drawn back far enough to snap in behind a new tooth of the ratchet 94, but only rubs back and forth a certain distance on the inclined side of the tooth.
  • each step imparted to the platen by the pawl 82 turns the ratchet ll forward, so that as a column of figures is printed, the next tooth of ratchet 94 gradually creeps toward the front of the machine.
  • this on-coming tooth will have reached a position so near to the normal position of pawl 95 that when said pawl is drawn back to its usual limited distance, the pawl will drop in behind said tooth, and when the pawl is then advanced on the return stroke of main shaft ll, said pawl will advance said on-coming tooth to the position shown in Fig. 5, which brings to printing position the first line of the next form, skipping the spaces containing the heading of such next form. It will be understood that even this limited movement of the pawl 95 turns the platen much further than pawl if can turn it, due chiefily to the fact that it acts through pinion I! which is of much smaller diameter than ratchet II.
  • next item will therefore be printed in the first writing line position of said next form.
  • Successive items may continue to be entered on the second form until a total card (following a space card) is reached. This will result in printing the total two spaces from the last entered item as in the instance previously described.
  • the pawl 05 will be given a full feed motion, due to the fact that the stop II has (been withdrawn by the rocking of the total taking shaft 43 as hereinbefore described, and will result in turning the platen an extent sufficient to bring the next bill form to a position where the next item may be entered in the first line thereof, and so on the operation may be repeated as hereinbefore described.
