Abstract

674,272. Locking rods. SCHRANZ, R. Jan. 4, 1951 [Jan. 20, 1950], No. 1573/50. Class 80 (iii). [Also in Group VI] The toothed rack 10, meshing with a pinion 11 is normally held against movement by a pawl 13 mounted on a pivot 14 and engaging a ratchet wheel 12. The spring 15 which normally urges this pawl into engagement with the wheel is attached to a partially rotatable cover 9 which, when moved slightly clockwise from the position shown, carries the spring around until it bears on the projecting tail 18 of the pawl and thereby raises the latter out of engagement.
