one to two and a half inches in diameter, by from 12 to 36 inches long. They are operated by hand or by power. Fig. 122 shows light rollers which are also formed with grooves for bending wire of various gauges. Such machines are also fitted with spur gearing and fly-wheel in place of the winch-handle for heavy work.

Circle Cutting Machine. Fig. 123 shows a plain circle cutting machine. The sheet to be cut is held in the end of a long jaw, which can be moved along the

bed to give a radius of as much as nine inches from the cutters. The cutters are of hardened steel carried in a fixed head, and operated by gearing. In more powerful machines, sheets 48 inches in diameter by 1/8-inch thick can be cut. Rings as well as discs can be cut. In one type of machine, the sheet to be cut has a small hole drilled in the center for fixing the sheet in the bow or arm.

Cornice Makers' Shears. As shown in the illustration at Fig. 124 these shears have an automatic holddown attachment, gauges for squaring and cutting at angles, and a device for working the back gauge with arm and slide in place of bevel gears and screws as heretofore used. The lever is operated from the

center of the shears on a graduated arc which indicates the position of the gauge, and from the front instead of the back of the shears. To cut sheets 3/4 to 11 inches wide, simply move the lever to the corresponding measurement indicated on the arc. To cut from 11 to 20 inches in width, move the gauge to the second

pocket in the slides and operate the lever in the same manner as in cutting narrow widths.

Cornice Makers' Brake. The machine shown in Fig. 125 is exceedingly well made and simple in construction, and of equal merit with any brake of its class.

This brake is warranted to bend No. 20 iron perfectly straight its entire length without springing. It is easily and quickly operated. Seven formers are furnished with each machine for making circular bends.

Folding Machine. As now made, the machine shown

in Fig. 126 will turn locks of different widths on any length of sheet. To turn an edge longer than the length of the machine, use the round rod, placing it so that the sheet will be put into the machine over it and

turn the folding bar against its round surface, making a slight bend the entire length of the sheet, and repeat this operation of bending until the lock is finished, or far enough to close it down in the ordinary way. In turning edges on long sheets it will be well to turn the edge slightly at first and repeat the

process of bending until finished. To turn wider locks than the depth of the folding plate use the steel strips under the plate to increase the width, and operate the machine in the same manner as without them.

Sheet-iron Folding Machine. The machine shown in Fig. 127 has an improvement consisting of a round steel rod, against which the fold is completed, thereby preventing the edge of the frame from being worn off,

thus rendering the folding plate more durable and insuring a lock of uniform width of entire length, as variations in the hardness of the material will have no effect upon the uniformity of the lock.

This rod can be replaced at small expense.
