p.168 HAND-FORGING manner. Instead of the center being cut out, it is left on, and the part on each side of it is cut off. In making this part of the hinge, a T weld is made with two pieces of stock; then the eye is formed and welded. The stock for the scroll ends is first drawn out on the horn of the anvil, and then the scroll is formed in shape. The tail of the hinge is formed from a piece of wider stock and then welded to the bar that has the eye on. The tail is made by splitting the stock into three parts as shown at D. The center part is cut shorter than the outside pieces. These prongs are then formed into shape. Fig. 111 shows some hinges that may be made from stock 1/16 or 1/8 in. thick. The eyes are not welded, but turned loose, and the projections are then filed. The open or pierced work is first drilled, then cut out with a small, narrow cold chisel. In Fig. 112 are shown door-keeps and hinges. The stock for the plates is 1/16 and 1/8 in. thick. The door-keep at A has a handle which swings from a pivot. The pivot is to go through the door and has a piece fastened to it with a set screw. This piece holds the door, and when the handle is turned the door is released. The keep at B may be used either for a door or window fastener. The latch has a spring so that it will snap when the door is closed. |
