Our invention has for its prime object to secure a greater universality and more perfect control in the presentation of the work held in the cutting or dividing head of a milling machine, but its general features will be found applicable in shapers, planers, and other Machines on which it may be desirable to cut work at an angle. Its main points may be summarized in the statement that the mandrel or work-carrier is permitted, for the purposes of adjustment, first, rotation upon a pivot perpendicular to the supporting bed or carriage; second, rotation or oscillation upon a pivot at right angles to the first; and, third, a rotation upon its own axis, thus allowing the work an adjustment representing the resultant of any one or more of the others; also, that provision is made for a primary adjustment of the index dial to determine 'the interval between the kerfs, and for a secondary adjustment subordinate to the first, and without disturbing the index-pin, for the purpose of a fresh cut in the same kerf, whereby, especially, the kerfs of bevel - wheels may be suitably converged from outer to inner end. |

Figure 1 is a front elevation of a machine embodying our improvements, certain parts not necessary to the description being broken away. Fig. 2 is a vertical longitudinal section through the head - stock and the parts which it carries, showing the means for adjusting the spindle and face-plate thereon. Fig. 3 is a top plan view of said head-stock and mechanism carried thereby, and Fig. 4 an elevation from the inner end thereof; Figs. 5 and 6, respectively, details in side and edge elevation of the face-plate and the improved clamp or chuck mounted thereon; Figs. 7 and 8, sectional and face elevations of the tail stock and its accessories, and Fig. 9 a detail in elevation of a center adapted to said stock; Figs. 10 and 11, horizontal sections of the tail stock on the correspondingly-numbered lines in the two foregoing figures. A is any usual and appropriate frame for the machine, supporting between its main portion and an overhung arm, A', an arbor, a, which carries the cutter or cutters a', said arbor, as customary, being mounted upon a live spindle in the main frame and a center in the overhung arm, so as to be removable to interchange cutters. On the body part of the frame, beneath the overhung arm, we form suitable ways or guides, upon which slides a knee piece, B, to support the clamp-bed and traversing carriage. An upright screw, B', is threaded into a step at the foot of the frame and collared in a lug or cross-bar, &, from the knee-piece, so that whenever it is turned this knee-piece may be adjusted up and down toward or from the cutter, carrying with, it all the parts which it ultimately supports. |
