(5.) The combination of mechanism as described with the ordinary brake-lever mechanism, so that the brakes may be actuated by the ordinary brake-lever handle or by the mechanism combined therewith, substantially as described. (6.) The combination of mechanism for acting directly upon a shortened ordinary brake-lever to apply, hold on, and release the brakes from either side, substantially as described, and illustrated by Figs. 12 and 13 of the drawings.
