Definitions

  • This invention relates to a paper feeding device for a calculating machine and particularly pertains to means to suppress a paper feed on the first cycle of a two-cycle total-taking or sub-total-taking operation in a machine that normally feeds record material one space each ma- :chine cycle.
  • the invention includes certain novel features of construction and combinations of parts, a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.
  • Fig. 1 isa view of the right side mechanism of the machine with the carriage removed.
  • Fig. 2 is a right end elevation of the paper carriage, showing the paper-feeding mechanism.
  • Fig. 3 is a detail of the paper feedbail and pawls.
  • Fig. 4 is a perspective of part of the mechanism of Figs. 2 and 3.
  • Fig. 5 is a rear elevation of the paper feed suppressing mechanism.
  • Fig. 6 is a right side elevation of the total-taking control linkage which disables the suppressing mechanism of Fig. 5.
  • the rear drive shaft 20 (Fig. 1) rocks first counter-clockwise and then clockwise during a machine cycle of operation.
  • an arm 21 (see also Figs. 2 and 4), having a stud 22, which normally rests against the end of an arm 23 of a bracket formed by the arm 23 and an arm 24, pivoted on a pin 25, supported in a rearwardly-extending portion 26 of the machine.
  • the free end of the arm 24 is bent over and bolted to the arm 23 to form a bearing surface 27, on which is mounted a roller 28, which bears against the forward surface of a paper feed bail 29 supported by an arm 30 pivoted by a screw stud 31 to the right frame plate 32 of the paper carriage.
  • the left end of the feed bail is supported in a similar manner.
  • a spring 33, wound around the stud 31, has one end resting against a stud on the frame plate 32 and its other end resting on the arm 30, so as to urge the feed bail to rock toward the roller 28.
  • a platen feed pawl 34 Pivoted to the upper end of the arm 30 is a platen feed pawl 34 (Figs. 3 and 4) having a tooth 35 adapted to cooperate with a ratchet wheel 36 secured to a platen support shaft 37. Rocking of the feed bail will turn the platen a step, the distance being controlled by the position of a lever 38, which, through a cam edge 39, controls the timing of the engagement of the pawl 34 with the wheel 36.
  • the paper carriage is formed of the right side plate 32 (Fig. 2), a similar left side plate, and various cross bars and shafts, and is mounted for cross-tabulating movement by bearings on a support member 40 and another support, not shown.
  • a support member 40 and another support not shown.
  • a lever 43 Pivoted on a stud 41 (Fig. 5) on a back frame piece 42 of the machine is a lever 43, normally held in the position shown by a spring 44, where the upper end engages a notch 45 in the arm 23. If this condition prevails during a cycle of machine operation, the paper-holding platen will not be given the feeding movement.
  • the shaft 20 rocks first counter-clockwise and then clockwise during a machine cycle.
  • the forward end of the link 47 is pivoted to a plate 48 secured to a cross shaft 49, which, also, is rocked first counter-clockwise and then clockwise during the cycle.
  • Pivoted to the right side frame plate 50 is a lever 51 having a downwardlyand rearwardly-extending leg 52 bearing against a stud 53 on an arm 54 secured to a hub 55 (see also Fig. 5) pivoted on the right frame plate 50.
  • the lever 51 (Fig.
  • the total-taking and sub-totaltaking operations are two-cycle operations. Such are initiated by keys, not shown here but shown in the Frieberg et a1. application before mentioned.
  • a total key when operated, bears down on a stud 72 on the total slide 61, moving it downwardly and rearwardly to a point where the nose 59 cannot move into the notch 60 but hits the rear edge of the total slide, such movement not being sufiicient to move the arms 54 and 64 a sufiicient distance to move the lever 43 (Fig. out of blocking position.
  • the sub-total key when operated, bears down on a stud 73 on a sub-total slide 74, moving it downwardly and rearwardly, carrying the total slide 61 with it, with the same result on lever 51.
  • the total slide stud 72 extends into a slot 75 of the sub-total slide to couple the two slides together in sub-total slide movements.
  • a bell crank lever 78 pivoted to the machine frame, is rocked counter-clockwise at the initiation of the first cycle, allowing the latch 77 to drop to where it rests on the top edge of a total link 80, which has a notch 81 thereon.
  • the slide 76 has moved completely forward, and an ear 82 on the latch 77, carried thereby, has dropped into the notch 81 under the urge of a spring 83, and, on return movement of the slide 76 in the last half of the first machine cycle, the total link 80 is moved to the right.
  • the total link 80 is pivoted to a swinging support 84 at its front end and is pivoted to a total bell crank lever 85, pivoted to the right frame, at its rear end.
  • the movement of the link 80 rocks the bell crank lever counter-clockwise as seen in Fig. 6, lifting up on a link 86, pivoted to its upper end.
  • the link 86 is resiliently coupled, by pins 87 and 88, slots 89 and 90, and a spring 91, to a link 92, pivoted to an arm 93, pinned to a shaft 94, journaled in the machine frame.
  • the shaft 94 is rocked counter-clockwise as seen in Figs. 1 and 6. Pinned to the shaft 94 is an arm 95 (see also Fig.
  • a machine of the class described having a cyclicallyoperable main operating means which performs one cycle of operation on item-entering operations and two cycles of operation on total-taking or sub-total-taking operations, the combination therewith of record material feed means spring-urged in a feeding direction but normally held in a home position while the machine is at rest; blocking means normally blocking the feed means from movement, said feed means making a feeding excursion once each machine cycle if the blocking means has been moved to ineffective position at the commencement of a machine cycle; control means operable to move the blocking means; a lever urged to move from a home position but held there by the main operating means while the machine is at rest, said lever being permitted to move to a full extent during the first half of an item-entering machine cycle but returned to home position at the close of a machine cycle, and said lever, when moved to its full extent, operating the control means to move the blocking means to ineffective position; a total control means which is moved to initiate a total-taking or a sub-total-taking two-cycle operation,
