Abstract
519,102. Reducing or finishing curved surfaces. MILTON, A. Nov. 7, 1938, No. 32200. [Classes 60 and 145 (i)] [Also in Group XXII] Internal or external curved surfaces in metal, wood &c. are produced or finished by shaping tools, milling-cutters, grinding-wheels, flame cutters &c. in a machine which comprises a tool-head adjustable along an arm pivoted about an adjustable centre and oscillated by means engaging the other end. As applied to shaping surfaces the tool 3', Fig. 2, is mounted in a clapper box 2c on a head 2 adjustable by a screw driven by a hand wheel 2b along an arm 1 pivoted at 4 to a slide 5 adjustable in ways 6. The work is mounted on a table 16 adjustable on ways by known feed means. When it is required to machine a curve of which the radius changes corresponding adjustments of tool head and table are made. When it is desired to machine two curved surfaces on the same piece of work, the slide 5 is employed to facilitate obtaining the exact adjustment prior to commencing the second cut. The arm 1 is oscillated by a slide 13 reciprocated, for example, by the usual shaper mechanism. A pin on the slide engages a slot in an eccentric mounted in a strap on the end of the arm.
