Abstract

777,016. Copy-milling. BLACKBURN & GENERAL AIRCRAFT, Ltd., WALKER, S., BANCROFT, T., and DUCKER, G. B. Sept. 20, 1955, No. 26809/55. Class 83 (3). A beam milling maching comprises a movable mounting 3, carrying the cutter 4, and a pneumatic device 9 which raises the cutter from the work 8 in the event of a power failure. Movements of the cutter, together with its motor 5, are controlled by an hydraulic copying device including a cylinder 7. If the hydraulic pump fails, a pipe bursts, or the electric motor driving the pump stops, the drop of pressure in a line 13 allows a spring 18 to move a valve 17 to connect an air-pressure line 19 to exhaust. A piston 9<SP>1</SP> is then moved immediately to raise the cutter 4 to its upper position.
