Abstract

12,131. Moorwood, H. S., Moorwood, J. M., and Travis, W. J. May 28. Milling; planing; lathes; work-holding devices. -Twist drills, taps, reamers, &c. are held between multiple-spindle headstocks during the groove-cutting operation. The invention is described with reference to milling-machines, but is stated to be applicable to other machinery. The Provisional Specification states that the apparatus is applicable for lathes and planing-machines. A headstock A and tailstock B, Figs. 1 and 4, are mounted in line on the machine table, ribs C on the headstocks entering a groove in the latter. The table is set so that the axes of the drills make an angle with the revolving cutter suitable to the pitch of the groove, and the spindle ends A', A<2>, A<3>, are staggered to correspond with this inclination L. The spindles receive the taper ends of the drills or of chucks holding the latter and are geared together by pinions aud idle wheels. The central spindle is coned at A<4> for connection to the dividing-head, and is slotted at H for drifting out the work- The work is removed from the other spindles by set-screws E. The centres of the tailstock are ground to have points near the top of the periphery to give clearance for the revolving-cutter, and are provided with adjusting-screws I<3> and clamping-screws J<3>.
