the pipe at the same time it is crimped. They have steel rolls. When crimping only is desired, the collar is substituted in place of the ogee rolls. They are adapted to material as thick as No. 22 gauge.

The machine shown in Fig. 85 can be regulated to crimp deep or shallow or of any uniform depths by means of the thumb screw near the handle, by lowering

one or tightening the other-the upper shaft can be tipped either inward or from the handle as desired.

The machine shown in Fig. 86 is very similar to that illustrated in Fig. 85, except that it is arranged to be operated without the beader rolls. This allows the machine to crimp close up to a bend or angle. It will be found serviceable for cornice work.

Rim Machine. The machine shown in Fig. 87, will form, flare and edge straight strips of tin or other metal at one operation, it contracts but does not corrugate the metal. It is adjustable so that rims of different widths can be formed. It is well adapted for general use in shops, as all strips of metal can be utilized.

Beading Machine. Fig. 88 represents an entirely new beader. It is most carefully made and is an excellent and desirable machine. The rod in front is designed as a guide rest, on which the cylinder or vessel

may rest while forming the bead, and revolves without guidance by the hand.

The machine is made with interchangeable parts, and is heavy enough to bead No. 20 iron. Crimping rolls can be furnished to fit these machines, and are with straight corrugations.

Tucking or Crimping Machine. The machine shown in Fig. 89 is used by manufacturers of canning boxes, and is intended for contracting inward or expanding outward the top or bottom edges of can bodies. It can be used on maerial not thicker than No. 27 gauge.

Crimping Machine. The machine shown in Fig. 90 will put bottoms on all cylinders of a diameter not less than 211⁄2 inches, and in length not exceeding 71% inches. The smaller size can be used for cylinders of a diameter not less than 111⁄2 inches, and not longer than 6 inches. They can be used on metal not thicker than No. 27 gauge.
