The gauges are so arranged as to be adjusted with ease and accuracy, and the top roller is adjusted by means of a foot treadle. These machines can be made to run by power.

Forming and Beading Machine. Fig. 91 represents a machine for forming and beading strips or narrow widths of metal, such as milk can bands, furnace bands

as wide as 6 inches. It can be made in different lengths from 6 to 16 inches between housings, and will form cylinders as small as 3 inches in diameter.

Power Beading Machine. The beading machine illustrated in Fig. 92 is designed to be run by power. They are furnished with pulleys 10 inches in diameter, having a 3-inch face, and have the same number and size of rolls as the regular beaders.

Double Seaming Machines. The seaming machine, illustrated in Fig. 93, will double seam vessels made of metal no heavier than No. 22 gauge, and of a diameter not less than 934 inches, and not deeper than 15% inches.

The lower horn is encased in a heavy casting its entire length, giving great strength for the purpose of working very heavy material.

This machine is made to be run by hand or power. A double seaming machine with setting-down attachment is shown in Fig. 94.

The setting down attachment to this machine will set. down any work that can be double seamed on the machine. It works rapidly and accurately, and an inexperienced workman can use it without difficulty. It is also intended to be used on work that does not require to be double seamed, and to a large extent will

take the place of the setting down in the set of machines. Eleven discs are furnished with each machine as follows: Flaring discs, 48, 43%, 534, 64, 85% and 10% inches. Straight discs, 5, 534, 6, 61⁄2 and 8 inches. It is adapted to material as thick as No. 26 gauge.

The machine shown in Fig. 95 is more readily adjusted to double seam vessels of different sizes than any other manufactured. It is also the most expeditious in its operation. It acts more favorably in passing seams or locks, because the pressure to set down a

double seam is obtained by means of a foot lever, which yields as the roll passes the seam. It is well adapted to wash basins, pans, etc., and will do any work that can be done on similar machines.

Elbow Seaming Machine. A plain elbow seaming machine is shown in Fig. 96, it is adapted for either hand or power.

Wire Straightener. Fig. 97 shows an eight-roll wire straightener, with central standard. This straightener
