The jaw, or forkedend, is opened with a common wedge in a bulldozer. The forked end of the hanger is then reheated and brought toa welding heat. It is placed in the forging machine and thejaw is finished and that end of the body of the hanger is com-pletely welded together by the dies and former shown at theright in Fig. 3. The slotted end of the hanger is then heated andthe slot is punched with the dies and punch shown at the leftin the same photograph. The center of the hanger is drawn to.

Spring Band.—A spring band for an under-hung type of springand the dies and former for forging it are shown in Fig. 4. Theband is formed from a 1 by 5 in. bar of commercial iron. Thebar is bent to suitable shape to go into the die; a filler is placedbetween the two pieces and it is completed in one stroke of themachine. This makes a strong spring band at a very low cost. Drawbar Yoke Filler.—The filling block for the back end ofa curved drawbar yoke, and the dies and former for making it,are shown in Fig. 5. These blocks are usually made of malle-able iron, but it has been found that they may be made morecheaply by forging them. The forged block is made from piecesof different size arch bars, varying from 1 by 3 in. to 1% by 4in. The pieces are cut to the proper length to insure t
