Abstract: A stiffened elongated cutting blade for use in a cutting apparatus of the type employing an elongated cantilevered cutting blade for cutting layups of fabric or other similar sheet material, and reciprocated along its longitudinal axis when actively cutting. The blade is a compound part made up of an inexpensive, reversible and replaceable edge member insert which provides the cutting edge and an associated holder supporting the insert for substantially its entire length along its rear edge and serving to reduce lateral and rearward deflections. The insert is held in the holder by a mechanical interfit between the insert and holder at its lower end and in mechanical engagement with the holder at its upper end and is easily releasable from the holder to allow its reversibility and replacement after the cutting edge has dulled or worn beyond a desireable point.

Abstract: In a compass saw formed as a hand-held machine tool a flat saw blade is connected with a flat reciprocating rod by a connecting device which comprises a cup-shaped clamping sleeve screwed on a rotary member formed with a through hole extended in the direction of elongation of the reciprocating rod the end of which is inserted into that hole. The shaft of the saw blade passes through a bore formed in the clamping sleeve and partially extends into the hole in the rotary member. Two opposing pins formed on the shaft of the saw blade limit the extension of the saw blade shaft into the hole of the rotary member. The end of the shaft is pressed against a recess formed in the reciprocating member, on the one hand, and the pins of the shaft are engaged in depressions formed in the rotary member, on the other hand, whereby clamping of the shaft of the saw blade with the end of the reciprocating rod in the clamping sleeve is ensured.

Abstract: An elongated blade has a notch in its leading edge, with parallel chisel edges adapted to chop through the oriented fibers (boron or graphite) of uncured sheet material as the blade is reciprocated vertically at a high frequency relative to its forward velocity (five cycles per blade width). The notch is about half as deep as the blade width and has a vertical extent (between the chisel edges) of about 60 percent of the blade's vertical stroke. The blade has a lower edge which forms a 135 degree angle with it's leading edge, and which lower edge is spaced below the lower notch chisel edge by approximately the width of the blade.

Abstract: An arrangement, preferably for clamping knife blades in power shears includes a longitudinal T-slot or dove-tail slot in the blade holder or the blade itself. Gripping means (16, 46, 76) are provided in the slot for engaging retainers (19, 47). The retainers or gripping means are connected to biassing means whereby the blade is pressed against the holder. The biassing means comprise spring means (28) or hydraulic clamping cylinders (36, 38; 61, 62). For relieving the bias of the spring means (28) there are provided hydraulic cylinders (22, 23; 51, 52), which release the blade when they are in operation. Alternatively the bias of the hydraulic clamping cylinders is relieved by counteracting spring means (43; 66) to release engagement of the gripping means.Since the blade is retained by means of retainers engaging in a groove, it can be withdrawn sideways, which enables rapid exchange. The hydraulic operation for clamping and release of the blade, respectively, is very rapid.

Abstract: A leaf stripping machine for tobacco and the like which consists of a framework with a large pinwheel rotatably mounted on a vertical plane at one end of the framework and a stripping implement with a V-groove mounted on a track oriented perpendicular to the plane of the pinwheel. A plurality of tines project horizontally from the face of the pinwheel near its perimeter so that the stock of a tobacco plant or the like can be skewered thereupon.

When the swath of tobacco is removed, then the stripper operator extracts the stalk from the pin and places it on a pile at the back end of the machine. The pinwheel is then rotated and the operation repeated.

Abstract: A novel compound angle cutting edge configuration on a die rule, slitter blade, hollow punches, shearing blades, etc. provides cleaner cuts on stock material with less tonnage, improved cutting and cleaner cuts. The die rule cutting edge includes a plurality of side by side notches on only one side of the cutting edge defining a plurality of equally spaced piercing points. A primary cutting edge extends from each piercing point substantially to a next adjacent piercing point and forms a compound angle with an imaginary line through the tips of the piercing points of between about one and fifteen degrees. In use, the cutting edges are axially pressed through stock material to cut blanks of predetermined configuration. The cutting action consists of the piercing points penetrating the material and then the primary cutting edges slicing the stock material from one penetration point, substantially linearly and unidirectionally, to the next adjacent penetration point.

Abstract: A powered saw developed for use in orthopaedic surgery has a strip-form blade carrier projecting from a casing in which it is driven at its inner end in an orbiting manner while further towards the carrier free end the carrier is constrained to allow longitudinal translation and pivotal movement. In consequence, the free end of the carrier, and all points of a blade projecting therefrom, are also subjected to an orbital motion. By appropriate location of teeth the blade can therefore cut in any combination of both sideways directions and also at its tip, and preferably has non-symmetrical teeth which are all raked in the same sense around the edge of the blade.

Abstract: A cutting blade for cutting a multi-layer stack of fabric sheets comprises a relatively flat elongated blade body having a leading edge and a trailing edge. The leading edge of the blade body has a knife edge for cutting through the multi-layer stack of fabric sheets as the cutting blade is moved forwardly into the stack. A bevelled tip is provided on the cutting blade for cutting through the fabric sheets as the blade makes a downstroke through the stack. The bevelled tip has a leading point at the leading edge of the blade and a trailing tip at the trailing edge of the blade. The leading tip pierces the top sheet of the stack and defines a rearward facing upwardly angled cutting edge which imparts a forward acting force on the blade to balance the rearward acting force imparted to the cutting blade by the forward cutting movement of the leading edge as the cutting blade moves forwardly through the stack.
