Car Brake.
Patent for a new and improved car-brake. This design consists in "brake-shoes [which] are jointed by pivots to brake-blocks of the usual form, which are suspended from the truck-timbers by suitable suspending links or clevises, so that they may have a free longitudinal movement when acted upon by the actuating mechanism, and said blocks and brake-shoes are separated by transverse brake-bars, in order that they may be kept truly in-line with the car-wheels at all times" (lines 16-25).
