The head, Fig. 152, is octag-onal, with circular ends 2y2 ins. diameter, and weighs 12 to 15 lbs. Tamping Bar.—For tamping ballast (except stone or slag), a bar is used 226 TRACK. about 5% ft. long, weighing about 12 lbs. Two forms are shown in and 154, the latter being the form adopted as standard by the Road-masters Association of America. The bar is generally of %-in. round iron,straight, with a flat piece 6 ins. long and 4 ins. wide, %-in. thick at the edge,welded on at an angle of 24°, so as to strike well under the tie. The upperend should be flattened to a chisel edge 2 ins. wide. Some bars have thelower end bent, made %-in. square, and having a tamping head Sy2 wide and %-in. thick. A larger diameter gives a better grasp for the hand,and in some cases a gas pipe handle is used to increase the diameter with-out increasing the weight. Lining Bar.—For lining and throwing track, a straight bar is used, , generally about 5 ft. 6 ins. long, weighing 22 to 30 lbs., and taperingfrom ly2 ins. square at the lower end to %-in. diameter at the top. A weightof about 24 lbs. is sufficient in a well made bar. The smaller end should beformed with a sharp diamond point, and the square (or lower) end should TRACK TOOLS AND SUPPLIES. 227 have a l^-in. chisel edge for about 3 ins. In throwing track, the flat end ofthe bar is driven into the ballast, and two men can take hold of it. In somecases the pinch bar serves as a lining bar, as it answers very well for thepurpose and thus saves the expense and trouble of extra bars.
