Abstract

317,510. Alexander, F. May 14, 1928. Line-spacing mechanism. - The line-spacing lever 13, Fig. 2, rocks a shaft 10 provided with a tooth 14, Fig. 8, which is guided by a slot in a bearing-sleeve 9 and engages an arm 15 pivoted on a lever 18 carrying a pawl 21. The pawl is normally horizontal and co-operates with a ratchet-wheel 8, but can be turned into the position shown in Fig. 2 when out of use. The arm is secured to a pin 16 pivoted in lugs on the lever. The lever is pivoted on a pin 19 and engages a returning-spring 20. The spacing- regulator consists of a curved member 23, Fig. 2, resting on the bearing-sleeve and formed with a finger-piece, and a lug which normally holds the pawl out of engagement with the ratchet-wheel. The member is rotatable to vary the position of the lug and is retained by a screw 24 which passes through a slot. The above-described mechanism is provided at each side of the carriage, and to permit employment of the same line-spacing lever with either mechanism, each shaft 10 is formed with a slot and grooves for engaging a mortise and cross-pins on the line-spacing lever. The ratchet-wheels engage detent-rollers 26 on springs 27 engaging projections 30 on a shaft 28 which can be rocked by means of a finger-piece 29 to the detent-rollers. Specification 315,044 is referred to.
