Abstract: 13,271. Holland, J. W., and Anthony, A. May 28. Making parts of velocipedes.-Relates to components for cycles and the like formed by stamping and pressing. The fork crown, Fig. 3, comprises two parts, each of which has a raised collar A<1>, B<1> and the two portions or wings A<2>, B' of a curved form in plan. The collars A', B' come together and encircle the steering-tube C, and the wing portions encircle the fork blades and are brazed or otherwise secured together. Projections may be formed on the plates to form a brake-rod guide and mud-guard attachment. Modifications are described, in one of which each of the parts is divided vertically so as to form separate stampings, and in another the collars A<1>, B<1> may be replaced by a tube. The rear fork end, Fig. 8, is formed by stamping from a blank, and has a semi-tubular portion D<1> and a channelled portion D' which form a D-shaped socket and also similar projections D<4>, D<5> forming a socket for the back stay. In place of the projections D<4>, D<5>, an ear may be formed and a dress-guard attachment may be formed if desired. Central slot are provided for the rear-wheel adjustment, and a bridge may be formed across the slot for the adjusting-screw. Several constructions of a rear-stay lug are described, in which the stamping is bent up to form a semi-tubular end and then folded so as to bring the ends together. Pedals consist of a piece of sheet metal stamped and folded to form a body shown at G<2>, Fig. 15, the ends g<2> being united by brazing or otherwise. Rubber or rat-trap treads G<3> may be inserted and end plates F<4> bearing pedal pins fitted thereto. Instead of inserting treads, teeth g<5> may be struck up from the metal. The brake clip, Fig. 18, consists of two similar stampings H<1> bowed at the middle H<3> to clip the tube and folded round to embrace a tube or ferrule H<2> which may receive the brake rod. Mudguard lugs are described in which the stampings are bent to suit the required purpose and loops may be formed which are tapped for the reception of the mud-guard stay. The bottom bracket M, Fig. 22, consists of two similar stampings M<1> each having semi-tubular projections for the reception of the frame members. The sockets of the bottom stays are completed by a bridging-piece. The stampings are secured together by rivets through the webs, and may be then brazed. A liner or split tube M<6> is preferably inserted, and within this are fitted the ball races M<7>, M<8>, adjustable preferably by means of the rack m<8> and pinion m<7> and clamped by means of bolts passing through the lugs m<1>. A seat pillar lug P, Fig. 24, is formed from a stamping having two semicircular ends which, when brought together, form a tubular portion P<2> and also D-shaped portions P<3> and a rear portion P<2>. An alternate arrangement is described in which the tube A<3> is formed in two parts, and in another arrangement the tubes P<3> are dispensed with, and a member provided for the reception of a rear fork. The steering-socket is formed from a blank with four half lugs which is bent round a mandrel, or the lugs may be formed separately and fixed to the tube, the edges of which are united by a fold.
