Abstract

1,117,583. Rotary impact tool. ROCKWELL MANUFACTURING CO. 11 March, 1966 [22 March, 1965], No. 10894/66. Heading B3N. In a portable pneumatic rotary impact tool, a valve means is provided for stopping the motor after a predetermined period of time has elapsed. The tool comprises a housing 10, a sliding vane motor 16 in the housing, a planetary reduction gear 23, a hammer 48, and an anvil 58. The valve means comprises a main air supply valve 90, Figs. 1 and 2, controlled by a trigger 100 and rod 92, a second valve 125, which is biased into its open position by a spring 144, and surrounds, and interconnects, ports 120, 122, a speed control valve 150, an adjustable time control valve 161, and a check valve 195. In operation, trigger 100 is depressed and valve 90 opens. Air flows to the motor through chamber 93, ports 120, 122 and valve 150, and also through valve 161, which is set to the required flow, and thence through a passageway 192 to chamber 81. As the pressure in chamber 81 increases, valve 125 is forced against spring 144 until port 120 is closed, and the air supply to the motor stops, a bleed 199 being provided to prevent a gradual cut-off.
