Abstract

20,389. Darling, J. Sept. 1. Ratchet-braces of the reversible type have a screwed spindle adapted to carry a drill at either end, and engaging nuts formed by tapping the cheeks of the brace frame. Pressure for drilling is obtained from a back-centre carried by a tube fitting over the spindle and abutting against the brace frame. When the spindle has been screwed out to its full extent during drilling, the whole brace is turned end for end, the tube and the drill are each transferred to the opposite end of the spindle respectively, and the ratchet mechanism is reversed. The brace is then ready for further drilling. The brace is operated by a hand-lever and quadrant B, Figs. 1 and 2, pivoted at B<1> and meshing with a pinion D loose on the boss of a ratchet-wheel E splined to the spindle. The pinion carries flanges D', D<3>, connected by a gapped ring D<2>. A double-ended pawl F is rockingly attached to the flange D<3>, and is set to rotate the ratchet-wheel in either direction by means of a lever G carried by a ring rotatable between the flanges as controlled by the gap. A shouldered catch H may be pressed, against the action of a spring, into the path of the lever G to effect the reversal.
