Abstract: 843,819. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 28, 1956 [Dec. 30, 1955], No. 39530/56. Class 100(4) In a decelerating mechanism for use with a typewriter having a travelling carriage, when a tape drum 20, Fig. 1, rotates to drive the carriage for tabulation a hub 10 is rotated through a member 26 and a one-way spring clutch 28, and with it a governor 2 through gears 4, 6. Tab check lever 30, Fig. 3, is set by being pulled to the left by a spring 56 acting through members 58, 60, 62, 38, 36 when released from a retainer 54 by tab lever 50. As cab check lever 30 is driven back to its original position during the last part of the carriage travel, a cam 58 is driven anti-clockwise about a shaft 8 through the members 36, 38, 62, 60. The cam 58, Fig. 1, is mounted on a hub 64 which is connected via a one-way spring clutch 66 to the hub 10 which drives the governor 2 as previously described, thus decelerating the carriage. At the end of a carriage return movement, a bell crank 78, Fig. 4, is rocked anti-clockwise by a slide 72 pushed by a stop 70. A cam 100 is rotated anti-clockwise through members 98, 96, 86, and a lever 84 depressed by an ear 82. The cam 100, Fig. 1, rotates a hub 102 which rotates a hub 16 via a one-way spring clutch. The hub 16 drives the governor 2 via members 14, 10, 6 and 4. The decelerating force for carriage return is adjustable by altering the relative positions of levers 88, 86 by turning a screw 92.
