Abstract

1405856 Filing machines NITTO KOHKI CO Ltd 10 Jan 1973 [20 July 1972] 1244/73 Heading B3L A reciprocating type portable filing machine has a main hand grip 10, a hollow main body 30, a fluid actuated cylindrical reciprocator 60 disposed in the main body, an axially slidable piston 80 in the reciprocator 60, a filing member 90 rigidly connected to the reciprocator and a roller bearing assembly 100 spaced between the main body and the filing member 90. In operation actuation of valve member 23 allows air to enter one of the chambers 77, 78 in the reciprocator. Consider air initially enters chamber 78 then the piston is forced to the left and the reciprocator moves to the right against spring 48. Such movement uncovers exhaust ports 63 allowing chamber 78 to be vented such that spring 48 can move the reciprocator to the left. The movement of the piston causes air to enter chamber 77 and a similar sequence of movement of the piston and the reciprocator occurs although the directions are reversed.
