Abstract: 615,766. Friction clutches. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. Aug. 13, 1946, No. 23929. [Class 80 (ii)] [Also in Group XXXIV] Distensible means for effecting radial movement of clutch friction members comprises in one form, Fig. 1, an outer annular tube 1, of resilient material such as rubber and having a substantially rectangular cross-section when not distended, which encloses a similar inner tube 2, the chambers 4, 3 defined by the tubes being supplied with fluid through inlet pipes 6, 5. The depth of the chamber 4 is such that little or no clearance exists between the adjacent walls of the tubes in the undistended condition. The inner walls of the tube 2 may be contiguous when the tube is not distended. The outer wall of the tube 1 may be thicker than the inner wall, as in the form shown, and may be reinforced with bands of bias-cut textile material. In a second form, Fig. 2, the inner peripheral wall of the tube 2 is adhesively secured to the adjacent wall of the chamber 4. In use, one tube is supplied with pressure fluid to engage the clutch while the other is charged with a liquid or plastic medium such as oil or grease to adjust the initial clearance between the friction members and the drum, the charge being increased when necessary to compensate for wear of the friction members. For this purpose, one of the pipes 5, 6 may be fitted with a grease cap or stauffer cup. Alternatively, the pipes 5, 6 may be connected to a valve control operable to admit pressure fluid to either tube whereby operation is assured even if one tube is defective.
