Title: Improvements in or relating to a variable speed driving mechanism
IPC: B41F13/00
Filed: 1955-04-20
Abstract: 768.789. Printing-machines. HARRIS- 'SEYBOLD CO. April 20, 1955 [April 21, 1954], No. 11392/55. Class 100(2) [Also in Group XXIV] Driving printing-machines, rotary machines. A driving mechanism, particularly for driving a printing press includes driving and driven pulleys, one of which is adjustable as to its effective diameter in response to the tension of a belt passing around the pulleys, and an idler pulley engaging the belt, actuating means being provided tending to move the idler pulley in a direction to reduce the effective diameter of the adjustable pulley, means for moving the idler to decrease the belt tension and increase the diameter of the adjustable pulley, and a latch for preventing actuation of the actuation means. A shaft 22 carrying a printing cylinder is driven 'through a pinion 21 by pinions 18 and 20 on a shaft 19, the pinion 18 engaging a pinion 17 on a shaft 13. The shaft 13 carries a pulley 12 driven by a belt 15 from a variable diameter pulley 11 the two sides of which are urged together by spring pressure. The belt 15 is tensioned by an ilder pulley 16 rotatable on a stub shaft 24 supported in an arm 25 carrying a pinion 26. A pinion 28, on a shaft 29 axially slidable and rotatable in a frame 14, engages the pinion 26 when urged to the right by a spring 35, Fig. 4. A handle 38 actuates the shaft 29 to slide it axially, to move the pinion 28 out of mesh with the pinion 31 and rotate it to set a pointer 39 along a dial 40. The pinion 31 carries a pin 41 retained in position by a notch in a bellcrank lever 42, 43, Fig. 1, attached to a tension spring 45. The speed of the cylinder on the shaft 22 is manually adjustable by pulling handle 38 outwardy against the spring 35 and then turning the shaft 29 until the pointer 39 is opposite the required speed setting, e.g., " 5 ". Rotation of the shaft 29 turns the pinion 26, thus actuating the pulley 16 to vary the tension of the belt 15 and so vary the diameter of the pulley 11. Should printing be interrupted, e.g. due to a misfeed of sheets, the resulting tripping of impression actuates a rod 48 upwardly, thus rocking the bell crank lever 42, 43 counterclockwise to release the pin 41. A compression spring 54 on a rod 52 attached to the arm 25 by a bar 58 rocks the arm 25 downwardly, such that the pointer 39 registers " 1 ", the cylinder then being driven at slow speed. Return of the rod 48 to its original position permits the spring 45 to return the bell-crank lever 42, 43 to pemit re-engagement with the pin 41 when the handle is returned manually to its original setting. In order to maintain a selected speed of the printing cylinder with impression "off", a handle 66 operating a cam 67 is rocked to displace the rod to the right, thus disengaging a hook 49 from a pin 50 and the lever 42, 43 which then returns to its latching position to re-engage the pin 41.

Patent GB-559469-A (GB)
Title: Improvements in automatic firearms
IPC: F41A19/33
Filed: 1942-08-17
Abstract: 559,469. Automatic firearms. PATCHETT, G. W., and STERLING ENGINEERING CO. Ltd. Aug. 17, 1942, No. 11520. [Classes 92 (ii) and 119] Relates to change-fire mechanism applicable particularly to recoiling breech-bolt guns of the blowback type. The sear 18 is mounted on the same pivot 17 as a trigger-operated sear-carrier 15 and has a forked tail 18b which receives the T-headed arm 20 of a sear-locking lever 19 pivoted on the carrier 15. The lever 19 has arms 19a, 22 which co-act with the finger 23 of a selector device, which may be set in positions B, C, D for safety, single shots, or automatic firing. The trigger 8 rocks the carrier by contact of a shoulder 14 with a roller 13 on the carrier. When the selector finger is in position B, it engages the locking-lever arm 22 and prevents movement of the sear-carrier and sear. In position C, when the trigger is pulled, the carrier is rocked clockwise and the finger 23 engages the arm 19a thereby rocking the lever 19 and disengaging its T-head from the sear tail. The sear is thus released and is urged upwards to recocking position by a spring-plunger device 21 which acts also upon the locking-lever. Upon release of the trigger, the carrier 15 together with the lever 19 are returned to cocked position, the former by a spring 11 and the latter by spring 21. In position D, the selector finger 23 cannot engage the locking-lever, which therefore holds the sear locked to the carrier 15, so that the sear remains depressed as long as the trigger pull is maintained. The sear is operative to hold the breech-bolt in open or closed positions, and when the mechanism is closed and set for "safety", the bolt cannot be jolted to open position. The trigger is shaped at 9 so as to fit closely in the triggerplate opening.
