Abstract

16,921. Raven, J. Aug. 21. Braces.-In a ratchet brace in which the rocking of the hand-lever causes a continuous rotation of the tool, the hand-lever 3 carries pawls 6, 7 engaging ratchets 8, 9 formed .on the periphery of bevelwheels 10, 11. A key 12, carrying shoulders 14, 15 and moved by a finger-piece 13, causes one or other of the bevel-wheels to drive the tool spindle 1. A holding-lever 17 carries bevel-wheels gearing with the wheels 10, 11 and forming a crown train. For feeding the tool, a screwed sleeve 24, carrying the thrust point, meshes with an internally screwed spindle 26 of opposite sense engaging the spindle 1. In the position of the finger-piece 13, shown in Fig. 2, on the hand-lever being turned to the right, the spindle is rotated by the ratchet 8 ; when it is turned to the left, the ratchet 9 is actuated and the spindle rotated through the bevel-gearing. To reverse the direction of motion, the key 12 is moved to make the shoulder 15 engage the wheel 11. Intermittent rotation may be obtainei by putting one pawl out of engagement.
