605,970. Building motions for textile ring spinning frames. PLATT BROS. & CO, Ltd., and PLATT, T. S. Dec. 17, 1945, No. 34080. [Class 120(ii)] In a ring spinning frame wherein the picking mechanism, by which the traverse of the ring rail is gradually raised, is formed as a separate unit from the building lever and attached to the machine frame at a height convenient for re-setting - purposes, the mechanism is provided with a resetting handle, which, in operative position, displaces propelling and check pawls from engagement with a ratchet wheel. Reciprocating motion is transmitted from the building lever (not shown) by a rod a Figs. 1 and 2, to a bell-crank lever c carrying a pawl h, Fig. 1, engaging a ratchet wheel i, which is also engaged by a check pawl j. Each pawl has a pin m, n, by which it may be disengaged from the ratchet wheel i when an arm o is raised. The arm o has a further arm q with a cranked end q<SP>1</SP> positioned in the path of a re-setting handle r, Fig. 2, when the latter is pressed upon the squared end of a spindle g for re-setting of the ring-rail, so that the pawls are simultaneously disengaged as the resetting handle is placed in operative position. The spindle g is rotated during the building of the cop by the pawl h and ratchet wheel i and, through gear u, Fig. 1, change wheels v, w, and gear x, movement is passed to a shaft d carrying the building chain bowl t. The extent of the movement which may be given to the pawl h is determined by an adjusting screw s, Fig. 2.
