Abstract: In a bicycle frame of the type wherein front and rear portions of the frame are connected together by a flexible spring member, the spring includes at least two laterally spaced, elongated rods extending between opposed mounting blocks in the front and rear portions of the frame, with the ends of the rods being held in the mounting blocks by a clamping mechanism that can be released to permit removal and replacement of the spring members when desired. A replaceable wire management tube is attached to the side of the crossbar of the bike by adhesive tape and extends at least a portion of the length of the crossbar. The bicycle frame can incorporate a folding mechanism that permits the front and rear portions of the bike to be folded together for easy portability of the bike.

Abstract: A lifting and storage apparatus is disclosed for handling a vise attachment for a vertical turret milling machine. The lifting means includes an articulated support arm that is adapted to attach at one end thereof to the glide or way provided on such machines for support and axial movement of the motorized milling tool. The articulated support is adapted at the distal end thereof to be clamped within the jaws of the vise attachment for support of the vise attachment when the movable bed of the milling machine is lowered. The articulation of the support arm allows free movement in the horizontal plane only; therefore, after the bed is lowered, the supported vise may be moved laterally to the side to a new position above the bed or to a storage position that is clear of the bed and of the work area related to the bed.

Abstract: A bicycle frame having a front frame portion with a rearwardly extending crossbar of elliptical cross-section, the major elliptical axis of which is vertically oriented. The rear of the crossbar is gradually tapered by flattening and widening into a substantially equilateral triangular configuration and then sharply reduced to an oblong horizontally extending opening where it is connected to a rear frame by a flexible spring connection.

Abstract: A bicycle frame has front and rear frame portions interconnected at their top by a flexible spring connection, that allows relative vertical flexing of the frame portions, and by a tension cable and compression spring between a forward portion of the front frame portion and a lower portion of the rear frame portion. Integral stiffening means included with the vertical center post member of the rear frame portion and with the horizontal crossbar assembly of the front frame portion are provided to minimize the tendency of the front portion of the frame to yaw laterally from side to side relative to the rear frame.
