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. 1902 Excerpt: ...work of a similar character. As the hand should be free to manipulate and turn the metal, the tongs are held in position by a link driven on over the handles as shown in Fig. 16. The elasticity of the latter serves to hold the work securely. Chisels are of two kinds, those used on hot and those intended for cold work. These differ in that the hot has a thinner and sharper blade than the cold chisel. Fig. 22 shows a hot chisel and Fig. 23 a cold chisel. Both are held on handles like a hammer head. The blacksmith holds the work in position on the anvil with his left hand, while the chisel is held at the point to be cut with the right. A helper Fig. 21. then strikes on the head of the chisel with a sledge. The work is usually facilitated hy putting an anvil cone, Fig. 24, in the square cutter hole at the tail of the anvil. A common form of hot chisel for cutting off round bars or trimming off rough edges is shown in Fig. 25. This is known as Fig. 22. Fig. 23. the gouge chisel. Another, but more unusual form is the square chisel shown in Fig. 26. The Flatter is a tool in common use and is shown in Fig. 27. It is for smoothing off the surface of metal that is being Fig. 24. Fig. 25. worked and thus removes hammer marks. It is held in the same way as the chisels and is struck with a sledge by the helper. Sometimes the edges are rounded. This makes it possible to work up close to rising portions and form fillets. The flatter is also made with an offset on one side as in Fig. 28. It is then called a foot tool. Fullers (Fig. 29), resemble the flatters in the uses to which they are put. They are also used for working into corners, Fig. 30, where it would be impossible to strike a satisfactory blow with a hammer. The fuller shown in Fig. 29 is known as the top-fuller....
