Abstract: 263,196. National Cash Register Co., (Assignees of National Cash register Co.). Dec. 21, 1,925, [Convention date]. Cash registers printing on inserted material. - An independently-operated machine is provided with mechanism for automatically stopping the drive at a definite point in the cycle in order that the operator may perform an adjustment. The machine may then be re-started by the operator so as to complete the cycle. The invention is described as applied to a machine of the Shipley type described in Specifications 8119/15, 176,781, 209,408 and 223,939, wherein provision is made for printing the item or total on two superposed account cards, the upper card first receiving the impression and then being ejected to enable the second card to be printed. By means of the invention, the machine stops after the first card has been ejected and the operator can then adjust the card carriage to select any line upon the second card for the impression. In addition to the usual roller 31, Fig. 2, for terminating the cycle by raising the link 32 and rocking the clutch and switch controlling lever 12, 13 the gear wheel 28 is provided with another roller 47 located 90‹ in advance of roller 31. In adding operations therefore the lever 12, 13 is rocked to engage a secondary lug 48 of the clutch and stop the machine when three-quarters of the cycle have been performed. The lever is held in displaced position by a spring-controlled latch 41 a pin 44 on which takes under a shoulder 45. The latch is linked at 40 with a lever 38, Fig. 2a, pivoted at 39 and connected at 36 with the auxiliary starting key 34. To complete the cycle therefore this key is depressed so as to rock lever 38 counterclockwise and force the latch to the left to free the lever 12, 13 which then turns counterclockwise to re-start the machine. To ensure stoppage of the machine even if key 34 is maintained depressed, the arm 13 carries a one-way pivoted stop 46 so that when the arm is raised by the roller 31 or 47 the latch moves to the right slightly, as permitted by a pin and slot connection at 37, and the stop engages the pin 44 to keep the lever 12, 13 in locking position. The latch is normally held inoperative when the machine is at rest by engagement of roller 47 with lever 38 (see Fig. 2). In total-taking operations bowever it is necessary to maintain the latch out of action throughout the whole of the first cycle and for this purpose the following mechanism is provided. A link 68 is lowered by the displacement of the total lever to total-taking position and thus permits a lever 59, Fig. 13, pivoted at 105 to rock to bring a latch lever 57 into co-operated relation with a stud 55 on the lever 38. The latch lever rests on a stud 64 carried by short arms 63 of a quatrefoil pivoted at 60 on the lever 59 and consequently the nose 56 blocks the stud 55 to prevent movement of lever 38 and latch 41 when the roller 47 starts on its first cycle. When however this roller has nearly completed a revolution it engages and rotates the quatrefoil to bring a long arm 61 into supporting position thus raising the latch lever 57 and freeing the lever 38 and latch 41 to allow the automatic stoppage during the second cycle as in adding operations. Specification 205,451 is also referred to.
