This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1911 edition. Excerpt: ...a hand-hammer, which completes the welding. Welding makes the rim ready for the spokes. The spokes are made two in one piece, of oval steel rod, cut to length, and slabbed on the sides to form a square tenon on each end to fit the square hole punches in the tire, and then formed Vshaped in the press, as shown in Fig. 202. There are four operations on the spoke V, only one, that of bending, being illustrated. First the spoke-blank is cut to length, then Fig. 201.--Welding wagon-wheel ri-on Justice hammer. slabbed on one end at a time for the square tenon, then formed by being laid on top of the V-horn of the press in the gages, which are of the same thickness, slotted so that the forming tool in the press-slide can bend both ends down into the completed form shown in Fig. 197. The spokes are riveted into the tire by a rapid pneumatic riveter, the piston being crank-driven, and the tool being a reproduction of the flat hand-hammer peen, t ltning round a little between blows. The spoke tenons are inserted in the rim by hand, being taken one at a time from the rod on which they hang at the workman's left, and then one spoke is grabbed in the press fixture vise and held hard by a long cam lever, all as clearly shown in Fig. 203, while riveting is done. The hammer is very fast, and the spoke slides down an inch or so while the riveting is done, which makes no difference as the atmospheric hammer follows it down all right. Riveting completes the rim and spokes, ready for assembling the entire wheel by adding the hub and side at the center of the bent Fig. 202-(rSpoke-forming press and tools. spokes which are seen in the row of wheels on the floor at the left in Fig. 203, and also in the pile of larger diameter wheels in Fig. 204, in which the...show more
