' Figure 1 illustrates a projectile body 'lfi having one end supported in the chuck i8 and its other end supported .by'the usual tailstock center 20. I also make use oflthe usual cross slide 22which carries the tool holder 2l forpresenting thetoo l 26 to the body It for shaping the face s28 o f the body to its finished contour.
Tothe cross slide-22 is secured an arm "38 {by Motion is imparted to the cross sli'de 23 7 through the medium of the arm 3?) by reaso'n'of a contour slide or bar 34 bolted, to the bar 360i the usual taper bar mount. Bar 35'is supported by brackets clamped to the bed 12 in the usual j manner; In the instantcase, the contour slide 5 34 is so contoured as to 'move thefcross slide 22 transversely of the bed l2 through longitudinal movement of the carriage l4 onthe bed for, moving the tool 26in a cutting-pathconforming to, the contour of the slide; 34. The slide 34 is contoured in conformity with the contour desired ,on the body I6. 7 r r Figure 2 illustrates a block 40 mg under- 7 i n'eath the arm 30 and provided ane pin 42 threadedly secured therein. The sleeve 44" is provided with a shoulder 48 engaging the bottom 7' I 40 A key 50 isv formed on the shoulder 48 and extends into the slot 46 to restrain the sleeve from rotation.
