Definitions

  • This invention relates to document handling apparatus and more particularly to apparatus for selectively positioning a document in predetermined positions in accordance with selected operating mode.
  • the disclosed embodiment of the instant invention provides for no document advance, for a single line advance, for a first total at a predetermined location irrespective of the number of prior entries and a second total at a second predetermined location.
  • the device is selectively controlled to cause a single input to affect three output modes.
  • the illustrated device may be used to position a document with respect to a print mechanism for the sequential entry of item amounts to a predetermined maximum number of entries. If prior to a total a machine cycle occurs which does not require the entry of an item amount'the document is not advanced. Upon taking a subtotal the document is advanced to a predetermined position irrespective of the number of items previously entered, and a total is also entered at a predetermined position following the subtotal.
  • FIG. I is an elevation of the control device of this invention partly broken away.
  • FIG. 2 is a partial section taken along line 2-2 of FIG. 1.
  • FIG. 3 is an axial view as seen from the right side of FIG. I at the interface between the driven gear and the arm secured thereto with alternate positions of the control lever shown in phantom view.
  • FIG. 4 is a partial elevation showing the cam follower following the cam external peripheral surface with certain parts and an alternate position of the reset drive pin shown in phantom view.
  • FIG. 5 is a partial elevation view showing the cam follower at the terminal position of a total cycle with a reset levelcocked and a phantom view of the reset drive pin in an alternate position immediately prior to triggering the reset lever.
  • an input drive shaft is joumaled through a sidewall I2 and carries a gear II.
  • An output shaft I3, joumaled through the sidewalls I2 and 14, carries at its distal, cantilevered end a feed roll I5 which cooperates with a pressure roll I6 to control the advance of a document 17 retained therebetween.
  • An arm 18 as seen in FIG. 2 is carried by the shaft I3 and abuts against a stud I9 mounted on sidewall I2 to restrain rotation in one direction and establish a home position for shaft I3 and the elements that rotate in unison therewith.
  • a torsion spring ZI concentrically mounted anchored to feed wheel I5 and the opposite end anchored to the pin 22 carried by sidewall I4 to biasarm 18 toward the home position of engagement with stud I9.
  • the ratchet wheel 29 is secured to and turns in unison with shaft I3 and has on its periphery a series of identical teeth, one tooth 3B of extended length and a peripheral portion devoid of teeth extending counterclockwise from the long tooth 311 includes seen in FIG. 3.
  • the ratchet wheel 29 also includes an axially recessed portion 33 wherein a lever 35 is mounted about a pin 36 with a tension spring 37 extending between apertures in the lever and ratchet wheel to urge the lever in a counterclockwise direction, as seen in FIG. 3, into abutting relation with ratchet wheel 29.
  • lever surface 39 functions in the same manner as the surface of an adjoining tooth whereas any force exerted approximately normal to the sur face 40 of lever 35 serves only to pivot the lever clockwise about the axis of the pin 36 and is ineffective to drive the ratchet wheel.
  • a channel cam 42 which has two arcuate channels 43 and 44 and an exterior arcuate surface 45 along which a cam follower stud 46 carried by lever 35 is guided.
  • a control lever 48 determines through its pivotal position which of three paths the cam follower stud 46 follows during an excursion from the home position as seen in FIG. 2 to the terminal position illustrated in FIG. 3. When the lever is in the position shown in FIG. 2 the cam follower is prevented from dropping into either of channels 43 or 44 and traverses from the initial to final position along the exterior peripheral surface 45 of the cam.
  • control lever 48 is in the full line position shown in FIG. 3 the cam follower element is permitted to fall into the channel 43 whereas with the control arm in a pivotal position shown in the dash-dot position of FIG. 3 the cam follower is permitted to enter and follow channel 44.
  • the ratchet wheel detent lever 51 and the trip and release lever 52 are shown in FIGS. 4 and 5.
  • the detent lever SI is pivotally mounted about pin 53 carried by wall I4 and is urged in a clockwise direction as seen in FIGS. 4 and 5 by the biasing force of tension spring 54 to hold the detent pin 55 which projects from the end of the lever to restrain the rotation of ratchet wheel 29 against the biasing force of torsion spring 21 (FIG. I) when the ratchet wheel'is rotated away from the home position.
  • Trip and reset lever 52 is pivotally connected through an elongated lost motion opening 56 about a pin 57 carried by detent lever 51.
  • the projecting pin 27 engages the surface 29 of the trip and reset lever 52 as shown in phantom view at M causing no efiect upon detent lever SI.
  • ratchet wheel 29 rotates to its terminal position as shown in FIG. 5 (the same operating position illustrated in FIG.
  • a pin 62 projecting from the ratchet wheel surface and extending toward wall 14 rotates into position where it first engages the surface of the trip and reset lever- 52 closely adjacent the comer 63 and through the final few degrees of rotation moves the lever to the position shown in FIG. 5 causing the trip and reset lever to be pivoted to a position shown in FIG. 5.
  • the pin about the cantilevered portion of shaft 13 has one end 27, when returned to the home position as shown in the dotted line position M, engages the trip and reset lever surface 60 causing a slight further overtravel to pivot the detent pin 55 out of engagement with the ratchet wheel 29 whereupon the torsion spring 21 (FIG.
  • control lever 48 With control lever 48 positioned as shown in FIG. 2 the cam follower 46 will proceed along the exterior surface 45 of the channel cam 42 and engage the ratchet wheel 29 only at the terminal location causing no rotational advance of ratchet wheel or shaft 13 connected thereto.
  • control lever 4-8 When control lever 4-8 is positioned as shown in the dot-dash position in FIG. 3 the cam follower 46 will be permitted in the home position to fall into channel 44 through the action of the biasing spring 30 permitting it to excursion along the channel and approach the areuate surface 66 at the outlet of channel 44 to cause the distal end of lever 26 to engage the ratchet wheel 29 and advance the ratchet wheel one tooth space between the outlet of the channel and the terminal position.
  • the cam follower 46 may be excursioned through the channel 44 during as many as 12 consecutive operations, each of which will advance the ratchet wheel one tooth space and correspondingly the controlled document the longitudinal distance corresponding to the rotational advance of the ratchet wheel between adjoining teeth as would be representative of the entry of items in an accounting machine.
  • control lever 48 When it is desired to take a subtotal the control lever 48 is moved to the position which permits the cam follower to excursion through the channel 43 permitting the drive element to pick up the long tooth 31 at whatever location it is disposed about the periphery, in accordance with whether one or l2 prior entries have been made, and move such long toothed to a common position for such total irrespective of the number of entries made on the document.
  • the cam follower When taking a total on the accounting machine the cam follower is once again permitted to excursion through the channel 43 causing a three tooth position advance of the ratchet wheel and corresponding longitudinal advancement of the document controlled by the feed wheel with the result that the total entry is likewise made at the same location on the document irrespective of the number of operations or items entered prior to the initiation of the subtotal.
  • This final total operation also brings the ratchet wheel stud 62 to the position shown in FIG. to set trip and reset lever 52 such that the final restore operation brings the stud 27 around to the home position to engage'surface 60, release the detent S5 and permit shaft 13 to restore to the home position shown in FIG. 2. It will be recognized that as shaft 13 is restored to the home position the feed wheel 15 reverses its rotation and restores the document 17 to the initial position.
  • a document feed and control device comprising:
  • a multiple track channel cam having first and second channels each extending from a common initial location to a common terminal location; a rotary driven element;
  • a drive member including a cam follower portion and a drivingportion operable to advance said driven element
  • selectively operable control means adjacent said initial location for directing said cam follower into a predetermined one of said first and second channels, said cam follower portion following said first channel to affect advance of said driven element in a first mode and following said second channel to affect advance of said driven element in a second mode.
  • releasable detent means to restrict movement of said driven element to one rotational direction and drive means for moving said drive member to cause said cam follower portion to move from said cam initial location to said ter' minal location and return;
  • said driven element comprises a toothed ratchet wheel which is engaged and driven by said drive member driving portion.
  • a document feed and control device of claim 2 wherein a portion of said ratchet wheel is devoid of teeth to limit the number of times such ratchet wheel can be advanced in one of said modes.
  • said ratchet wheel includes a tooth of increased radial length engageable with said drive member when the latter excursions through said second channel to affect a common final position of said ratchet wheel irrespective of the initial position of said increase length tooth adjacent said second channel.
  • control means comprises a control lever which controls access of said cam follower to said channels of said cam at said initial location, said control lever having a first position permitting access to said first channel, a second position permitting access to said second channel, and a third position denying access to either said first or second channels.
  • the document feed and control device of claim 6 funher comprising a terminal channel portion in said cam extending from said terminal location to and communicating with the outlets of said first and second channels and presenting a camming surface at a uniform radial distance from the axis of said ratchet wheel.
  • said cam further presents an exterior camming surface extending from said initial location to a position adjoining said terminal location such that when said drive member is pivoted in a second pivotal direction opposite the direction of advance of the driven element said driving portion follows the surface of the ratchet tooth next adjoining in said second pivotal direction causing said cam follower portion to be guided onto said exterior camming surface, whereby said cam follower returns to said initial position along said exterior camming surface.
