  • PAPER FEED MECHANISM Filed Aug. 22, 1954 s sheets-sheet 7 rurali..
  • the invention relates to the paper feed mechanism of bookkeeping and like machines. Some of the features of the invention are applicable to such machines generally, but certain features of it are especially applicable to record controlled tabulating machines.
  • the invention has for its principal object to provide certain improvements in the means for handling long Webs of paper, and especially where such webs are pre-printed to constitute a succession of separable forms, and more especially where it is also pre-folded.
  • the invention includes means for causing a long web to pass smoothly through the machine and to be disposed in neat and convenient form after being printed on by the machine, and without attention by the person operating the machine.
  • the invention has for one of its objects to provide means for imparting long feed movements to the paper under conditions and requirements more complex than usual, and preferably for doing so entirely automatically, without personal intervention.
  • the invention also contemplates various improvements in mechanism of the characterI indicated.
  • the invention is capable of various applications and of embodiment in various forms. One specific embodiment and application ,of it are shown and described herein.
  • the invention is herein described as embodied in a Powers tabulating machine, for tabulating records consisting of punched cards, and as applied to making out the monthly statements of the charge customers of a department store.
  • the statements are printed by the machine on a web of paper pre-printed in a succession of forms, the paper being in fanfold form and being restored to that form after passing through the machine.
  • the mechanism causes the name and address and account number of the customer to be automatically printed under the control of punched cards in a space provided for the purpose in the heading of the form.
  • the mechanism then automatically imparts a long feed to the paper, to position it for the entry of the rst item of the statement. When the last item of the statement has been printed, the
  • the machine is equipped with the usual lineto-line feed which operates as usual between the long feeds. It may also be equipped with a known form of hand paper injector and ejector which imparts long feeds to the paper, and there is no interference between that and the longfeed mechanism of the present invention. Means are provided for disabling the latter, by a simple setting of a handle, leaving the machine free to be operated as heretofore; andthe long feed of the present invention may be brought back into use at will by resetting said handle.

  • the head I8 contains several tabulator units, each of which may' include the usual register-actuating rack sectors 2
  • the operat'- ing mechanism comprises a continuously rotating transverse drive shaft 23 geared to make one rotation for each machine cycle and connected by a Stud shaft 24 on cam 36 and link 25 to oscillate a transverse shaft 26, which carries a series of arms (not shown) which are connected by links to the restoring bails for the numerical type sectors 22 and the printing hammers 21.
  • the usual main rock shaft 28 which, among other things, moves the registers into and out of mesh with the racks 2l has, in this instance, an arm 30, connected by a link 3
  • Some of the units contain the direct subtraction mechanismfarniliar to users of this lmachine and described in a certain application for Letters Patent, filed by William W. ,Lasken
  • This comprises reciprocatory pieces 31 linked to the respective type sectors 22 and each controlling an adding rack bar 38 and a subtracting rack bar 40,
  • the usual forward total shaft 42 is rocked on occasion by the usual link 43, and it in turn rocks the rear total shaft 33 by means of the link 44, as usual, in order to take a total from the rear registers 4l.

  • 'Ihe platen 46 (Fig. 3) has its shaft 41 journaled as usual in the paper carriage 48.
  • the platen is divided in two in a familiar way, and the novel feed mechanism is applied to the left-hand half of it; but this is immaterial.
  • the platen is provided at its left-hand end with the usual ratchet Wheel U and detent wheel 5I shown in Fig. 2 in which these parts are seen from Vthe right hand side, the platen being sectioned away.
  • Said ratchet is actuated one or two of its teeth at a time, or not atall according to manual adjustment, by a pawl 52, pivoted to a sliding link 63, which link is pivoted to an arm 64 on the lefthand end of the usual long pinion shaft 66, which extends the entire length of the platen and is joumaled in the carriage.
  • this pinion shaft is engaged by a pinion 66 on a stub shaft having an arm 61 connected by a ⁇ link 58 with a bell crank 80, pivoted at 6l to the right-hand end frame member of the tabulator head and influenced by a spring 62.
  • This bellcrank is connected by a link 63 with an angle lever 64 pivoted to said frame member at 66 and .having one arm thereof pivoted to a long link 66.
  • the latter has at its upper end a'slot 61 engaging a stud 68 on an arm projecting from the rock shaft 26.
  • the construction is such that the rocking of this shaft, acting through the train of mechanism described, rocks the pinion 56 and pinion shaft 55, and reciprocates the pawl52 to impart a suitable feed to the platen at'each machine cycle, unless something intervenes to prevent such an operation.
  • such intervening means is something applied in the form of a stop set in the path of a shoulder'69 on the lever 64, in which event the stud 68 lplays idly in the slot 61 andthe spring 62 is therefore unable to operate the line space mechanism.
  • Said spring has one end attached to a stud 18 on the link 66. The distinction between single, double and no spacing is made by differential stops set in the path of the return movement of the slide link 53.
  • the usual pressure rollers co-operate with the platen to'feed the paper.
  • the platen shaft is provided with a pinion 1l having the same number of teeth -as said ratchet wheel and driven by a gear 12, journaled on a stud 13, secured to the left-hand end plate of the carriage.
  • the Powers tabulator as heretofore manufactured, has sometimes included this gear, driven by a pawl 14 pivoted to a lever 15, which lever is pivoted on the stud 13 and is provided with a handle 16. This constitutes a hand device by which the platen may be rapidly rotated either for the original insertion of a new bill sheet, or for the ejection of the old one.

  • each sale to a charge customer is recorded on an ordinary Powers 90-column card perforated to designate the number of the customers account, the date of sale, the name of the goodssold, the department of the store from which they were sold, and the amount of the charge, or in other words, the price; also when the customer makes a payment on account, a similar card is punched, but punched with the amount of the payment instead of the price of the goods, and this card is so punched as to indicate that it represents a credit instead of a debit.
  • these charge account cards are sorted according to the customers account numbers, and the result of this sorting operation is a stack of cards arranged in groups, each group including all of the debit and credit cards of a single customer arranged in the order. of the dats: Into" this "bk there are inserted other cards for printing the name, account number and address of each customer.

Any debit items are printed in the column entitled charges as shown.

  • lThe bill forms 88 are printed on a continuous web, as shown in Fig. 13, the successive bills being separable from each other by lines 90 of perforations or other means of weakening. In the present instance this webof paper is folded in fanfold form and preferably the folds come at the lines 90 of separation.
