Abstract
A reciprocating and oscillating ram for a winding head is reciprocated and oscillated at high speeds by a single drive shaft and a rotary to reciprocatory and oscillatory movement mechanism including a carriage, adjustable Scotch yoke drive means reciprocally driving the carriage, a rack bar slidably mounted on the carriage and a pinion member engaging rack teeth on the rack bar and affixed to the ram. The rack bar follows reciprocal movements of a plate that carries cam followers driven by a cam mounted on the drive shaft. The Scotch yoke mechanism includes an adjustable length crank arm with a counterbalance. The movements of the carriage are counterbalanced by reciprocatory movement of a counterbalance carriage driven by a similar crank arm. Wire is guided to the ram by a non-rotating wire feed tube connected to the carriage for reciprocation therewith and projecting to the rear of the machine. A wire guide pulley is mounted on the rear end of the feed tube for guiding wire from a wire source.
