One of the walls 66 may be formed with an opening 3'2 and the lever may be provided with socket 14. In the socket is a spring pressed hall 15 adapted to snap into opening '52 to retain the lever against accidental rotation about the of pin 68 in the position of the lever shown in full lines. In this position, the lever may he against rotation, thus permitting the hand‘wheel 44 to be rotated for the screw adjustment of the slide. ' . . The friction of the wedge I96 between the brake wings 94 will retain the lever in braking position. In such position, the lever cannot be rotated side ways about the axis of the shaft 5|.
