Abstract: A brake assembly for large mechanical presses of the type which employ large gears and operate at relatively high speeds. The brake assembly is especially adapted to reduce noises emanating from the brake housing of such presses due to sudden shocks and stresses placed on the mechanical gearing and drive means of the press when the reciprocating slide of the press delivers its power stroke for performing work functions on a workpiece supported on the bed of the press. The brake assembly and the clutch of the press are coupled to the main driveshaft of the press, and the brake assembly may comprise an integral unit with the clutch or it may be a separate unit.

Abstract: A sound abatement device for large mechanical presses of the type which employ large gears and operate at relatively high speeds. The device is especially adapted to reduce noises emanating from the enclosed crown of such presses where the press gearing, drive means and bearings are located, and, to this end, the device desirably is positioned in openings in the base of the enclosed crown through which the pitmans or connecting links for moving the slide or ram of the press extend, and through which the crown generated noises normally are released. The device, while being positioned in the openings through which the pitmans or connecting links extend, does not interfere with, or impede, the vertical and oscillating movements thereof.
