Abstract

19,452. Hailwood, E. A. Feb. 28, 1908. Milling.-A milling-machine having one or more chucks mounted on a platform intermittently rotated by the reciprocations of such platform is provided with improved rotating and locking means, and with a knock-off motion, and with a telescopic drive for the reciprocating platform. The chuck E is mounted on the reciprocating platform B and is fixed to two ratchet-wheels D D<1> one above the other as the platform reciprocates, a spring-pressed pawl G gives an intermittent rotation to the chuck, and the chuck is looked in the forward position of the platform by a cam J<1> engaging a pawl J which locks the ratchet-wheel D. A ratchet-wheel Q<1> is actuated by a pawl R on the platform and carries a wiper Q, which engages a trip-rod p<2> and thus frees through trip-levers the spring-pressed arm N which puts out the driving-clutch M. Electro-magnetic means may be used to operate the knock-off means, the wiper Q being replaced by a contact-piece on an insulated wheel. The connecting-rod K, K<1> for reciprocating the platform is made telescopic, a spring bolt T' fixing the two parts. By this means, the platform can be moved farther back for fixing the work. The reciprocations of the platform may be performed by hand.
