Abstract
1,213,552. Rotary pneumatic motors. BLACK & DECKER MFG CO. June 20, 1968, No.29545/68. Heading F1F. A radially sliding vane in a rotor in a rotary pneumatic motor, particularly for a rotary portable power tool, e.g., an impact wrench, comprises a flat elongated member 47, Fig.1, of synthetic plastics material of high heat and wear resistance and low moisture absorption characteristics, e.g., phenolic thermosetting resins, inwhich is embedded a woven material including warp and weave threads 59, 61 disposed generally perpendicular to each other wherein the weave threads 61 disposed transversely to the vane are made of cotton, wool, linen, rayon, nylon or acrylic fibres which provide strength but at the same time are moisture absorbent and the warp threads 59 include threads of non-absorbent properties, e.g., glass fibre, to improve the longitudinal dimensional stability of the vane and allow closer manufacturing tolerances between the ends of the vane and, the end faces of the casing in which the vaned rotor is rotatably mounted.
