A carding engine including a frame, an axle, a cylinder mounted on said axle and rotatable therewith, bearing means between said frame and each of the ends of said axle, a bearing block housing said bearing means at each end of said axle, a bend spaced apart from each end of said cylinder and fixed to said bearing blocks, said axle ends extending through said bends into said bearing means, pivot means between said bearing blocks and said frame permitting swiveling movement of said bearing blocks about an axis parallel to said frame and an axis vertical to said frame.
Claim 3
Dependent Claim
56 words
A carding engine according to claim 1 in which said bearing blocks are formed integrally with said bends and a swivel pin is carried in said bearing blocks, said pin extending into a base block, said base block mounted for movement about said parallel axis substantially at right angles to the axis of the swivel pin.
