Abstract: 30,332. Jones, H. Sefton-, [Bates Machine Co.]. Dec. 28. Number-printing apparatus.-A number-printing apparatus of the kind in which the reciprocation of a handle depresses the wheels into printing position, changes them automatically, and inks them on the up-stroke, is constructed with an improved setting-mechanism of the type that permits any number to be repeated indefinitely or any desired number of times, and after advancing the numerals one digit to again print the same or a different number of times. The numbering-disks 22, Fig. 4, are carried by a shaft 21 in a frame 20, which is depressed by a rod 13, provided with a handle, against the action of a spring 17. The depression of the frame 20 raises a frame 38, which carries an ink-pad, and also oscillates a frame 28, which is loosely mounted on the shaft 21, and carries a pivoted multiple pawl 25 controlled by a spring 29 and provided with a tail 96 which may be held by a hook 95 carried by a shaft 90 when the pawl 25 is to be prevented from operating the disks 22. The hook 95 is caused to hold the tail 96 whenever a tooth 720, Fig. 9, on a flange 71 of a ratchet-wheel 65 is not in engagement with a space 97 between two teeth on a plate 92 carried by the shaft 90. When in the position shown in Fig. 9, the numbering-disks are actuated normally. To cause the disks to repeat the same numbers for a certain number of actuations, a shaft 52 connected to a dial 55 is rotated in a clockwise direction after releasing the dial from the action of a spring-catch 62 ; and the shaft, through a spring 69, also rotates the ratchetwheel 65, which, during the rotation, is released from the action of a detent 75 on a pivoted plate 73 by means of teeth on a disk 63 which engage a stop 78 on the plate. The plate 73 is provided with notches 80, 81 engaged by a bent spring 82 to keep the detent 75 out of or in engagement with the ratchet-wheel 65. At each actuation of the frame 28, a pawl 88 on the frame rotates the ratchet-wheel 65 through one tooth against the action of the spring 69, and when the wheel has rotated through a distance equal to the same number of teeth as the number of repetitions required, an enlarged tooth 68 on the ratchetwheel trips the plate 73, and the spring 69 returns the ratchet-wheel to its set position, but the plate 92 is first of all actuated so as to release the pawl 25 from the hook 94 and the pawl is thus allowed to actuate the number disks. A tooth 70 on the ratchet-wheel 65 contacts with a pin 64 on the disk 63 to stop the ratchet-wheel in the correct position. When a number is to be repeated indefinitely, the detent 75 is caused to engage a gap 670 between the ratchet teeth, and the wheel is thus not actuated by pawl 88. The end 89 of the pawl 88 re-sets the plate 73. When it is required to re-set the apparatus before a given number of repeats has been printed, the disk 63 is rotated, after release of the catch 62 from the dial 55, until the inclined side of its projection 64 contacts with the stop arm 78. The plate 73 is thereby moved to release the wheel 65, which moves under the influence of the spring 69. The disk 63 and dial 55 are then moved to the new position, the projection 64 acting on the pin 70 to move the wheel 65 to its new position.
