Abstract: A tubing cutoff die having a horizontally moving scarfing blade and a vertically moving cutoff blade. The tubing being cut off is held in clamping jaws movably mounted on the lower die shoe of the die and actuated by a cam extending from the upper die shoe. The scarfing blade is also mounted for horizontal reciprocation on the lower shoe and actuated by another cam fixed to the upper shoe. The cutoff blade is mounted on the upper die shoe. The two die shoes are reciprocably connected by post and bushing arrangements. There are three of these disposed so that the centerlines are at three of the corners of a rectangle. One of the clamping jaws is mounted on a holder reciprocably mounted on the lower die shoe and the other jaw is mounted on a second holder reciprocably mounted on the first holder. The mounting for the cutoff block provides for either of two rigidly located positions, for different tubing sizes, and the scarfing blade is also adjustable.

Abstract: A support means is provided with a pair of fixed dies aligned in spaced, horizontal relationship for receiving a metal strip having a base portion with edge portions extending in planes different from that of the base portion to be cut. Cutting die means are movably carried by the support means with actuating means connected to the movable die means for cutting the base portion and the edge portion of the metal strip supported on the spaced fixed dies with the cutting dies being shaped so that the angle cut on the base portion by the cutting die means is different from the angle cut by the cutting die means on the edge portions of the metal strip.

Abstract: An angle shears with two shear cutting members for cuts in two directions. The two shear cutting members are arranged to be moved independently of each other and have a divided drive. The cutting edges of the shear cutting members are arranged at small angles to the surface of the sheet metal to be cut.

Abstract: An apparatus for slashing tree trunks into logs including at least two knives positioned at an acute angle relative to each other which are forced through the tree to meet at a point on the other side of the tree, or to meet an opposite pair of knives in the center of the tree. As the two knives travel through the tree, wood between the knives is chipped away and severed from the tree. The chipped wood is thus removed from the surface of the knives so that the chips do not bind the knives as they pass through the log or tree.

Abstract: A double-cut tube cutoff machine for severing steel tubing in such a way as to produce minimum deformation of the tube in the severed area. The machine comprises a base carrying opposing die jaws to clamp the tube, and a ram assembly which moves vertically and reciprocally relative to the base. The ram carries a sharp-pointed severing blade which actually cuts the tubing. A first cam arrangement synchronizes the opening and closing of the die jaws to clamp the tube during a transverse slotting operation as well as during the final severing step. A second cam arrangement synchronizes the motion of a cross slide to ram movement to drive a slotting blade transversely across the tube to notch or slot the top wall part way through prior to the severing operation. The slotting blade is carried in a blade holder which receives inserts of varying thickness so slotting blades of conversely varying thickness all pass over the workpiece in the plane of the severing blade.

Abstract: Apparatus for feeding objects to a transport mechanism and transport and delivery mechanisms for the objects, and, in particular, apparatus for feeding books to, transporting them through the cutting stations of and delivering them from a two-station, three-knife book trimmer. The feed mechanism includes a hopper for holding books, a prestripper for stripping a book from the hopper and moving it part way to the front knife cutting station and pushers, which continue to feed the book to the first cutting station, with means coordinating the prestrippers and pushers. The transport mechanism includes a plurality of displaceable, e.g. upper transport belts and a plurality of belts in opposition to the displaceable ones, e.g. lower transport belts, which clamp the book, respectively, from above and below. While clamping the book, the transport belts travel with it to the side knife cutting station, halt for side knife trimming, and then move the book beyond the second station to the delivery mechanism.
