Fig. 88 shows a curved-gap tongs, Fig. 89 a bar tongs, and Fig. 90 a side-grip tongs. Other forms are illustrated in Figs. 92 to 99. To forge and put together a pair of flat bitted tongs (Fig. 93), of the most usual pattern, select a bar of good 1 in. square iron; lay about 3 in. on the inside edge of the anvil (Fig. 100) and "take down" the thickness to 1/2 in., at the same time "drawing" it edgeways to maintain the width at 1 in.; this is done rapidly, so as to have heat enough in the bar to proceed with the next step, which consists in turning it at right angles, and hanging the "bit," or part just taken down, over the front edge of the anvil (Fig. 101) and flattening the bar just behind it. The third step is performed by placing the work about 3 in. farther forward on the anvil, and again turning at right angles (Fig. 102), slightly raising the back end, and striking the iron fairly over the front edge of the anvil, alternating the blows by turning and returning the bar. Cut off the "bit" 3 or 4 in. behind the part last treated (Fig. 103). Prepare a second bit in exactly the same manner, and scarf down one end of each. For the handles or " reins," choose a piece of 1/2-in. rod, upset one end, scarf it, and weld it to one of the bits. Serve the other bit the same.
Punch a 3/8-in. hole through each, and connect them by riveting. Reheat the finished tongs and dress them parallel; then cool by immersion and constant motion in cold water. The other forms are made in a similar manner, dressing the bits in each case around pieces of metal of suitable shape and size.
