Abstract: A deburring tool comprising a barrel having a blade slot integrally formed in its top end and a blade having an aperture disposed therethrough freely positioned within the blade slot. A blade axle aperture is disposed through the barrel and the blade slot. The blade axle is positioned within the blade axle aperture and through the blade aperture in order to secure the blade within the blade slot. A resilient positioning member aperture is integrally formed in the bottom end of the barrel for receiving the resilient positioning member. The resilient positioning member maintains contact with the blade and exerts an outward force against it. The blade is able to retract if forced but will immediately extend outward due to the resilient positioning member as soon as any opposing forces dissipate.

Abstract: A clamp for indexable inserts used especially for turning. The clamp consists essentially of a clamp shaft and a clamp head combined with it in one piece. The clamp shaft can be secured to an axis-parallel clamping surface of a tool holder by a supporting surface obliquely transfixed by a clamping screw. The clamp head has an open-edged recess to take the indexable insert, one effective cutting corner of which projects on one side beyond the outer surface away from the support surface. In order to be able to adjust the distance between the clamping surface and the cutting corner, the clamp head has, in the free region between the recess, the supporting surface and the clamp shaft, a slot-like aperture having a curved cross-sectional shape open towards the clamp shaft. The clamp head can be elastically bent with respect to the clamp shaft under the effect of an adjuster.

Abstract: An abrasive tool such as a drill bit has a body with a working face (10). Undercut recesses (12) are formed in the working face (10). Cutting inserts (16) which present working ends (20) are located in the recesses (12). Locking means (24) in the recesses engage between the undercuts (14) and formations (22) on the inserts (16). This locks the inserts (16) against withdrawal from the recesses (12).

Abstract: A lathe tool includes a stiff shank and handle portion and, adjustably extending forward from the shank, cantilever fashion, an elongated resilient blade. The combination is configured and disposed on a tool rest so that, when the tip of the blade engages a downwardly moving surface of a workpiece, a vibration or chatter of the blade results and produces a three dimensional textured pattern on the workpiece. Pattern and texture may be selectively varied by adjusting the unsupported length of the blade (to control its frequency of vibration), by changing speed of rotation of the workpiece, by changing pressure of the tool blade on the workpiece, and by lateral and rotational manipulation of the tool.

Abstract: A rotary slot cutting tool having a flat sided disc shaped body with a central bore, a plurality of apertures spaced about the periphery of the body each aperture having in it a cutting insert held in position by the shape of the aperture against radial movement, each aperture being shaped in such a manner that on the application of a force acting radially outwards on the circumference on the bore of the body, faces of the aperture are caused to spread apart to permit removal and replacement of the inserts in an axial direction. The invention further provides an insert for use in rotary and other slot cutting tools.

Abstract: A tooth for use in a comminuter roll comprises a roll of spring steel having a first end formed into a point or other abrading shape. The tooth is compressed upon insertion into a mounting hole in the roll and the inherent spring of the steel tends to force the tooth back to its original size, thereby creating forces on the interior of the mounting hole to form an interference fit that holds the tooth in place in the mounting hole. In a preferred embodiment, the tooth is formed of a roll of spring steel having a G-shaped cross section. This shape provides an opening through the length of the tooth and also leaves a solid place in the center of the tooth to aid in tooth removal. A rod can be slipped through the lengthwise opening of the first tooth so that its end abuts the solid center portion of the second tooth that is colinearly mounted in the other end of the hole that the first tooth is mounted in. Tapping the rod will force the second tooth out of its hole without disturbing the first tooth.

Abstract: A fleshing machine for removing fat and fleshy membranes from a hide or pelt, which includes a fixed position roller with many shaped cavities.

Each knife has a shaped cutting head which, in use, protrudes from the surface of the roller. The knives and cavities are so shaped that each knife is capable of limited reciprocal movement in a direction perpendicular to the axis of the roller.

Abstract: A cutter for the deburring of bores comprises a rectangular edged cutter element having taperingly extending cutting edges, having clearance surfaces ground undercut and comprising a convexly ground contact surface on one end of the cutter head for contact with the internal surface of a bore. Two oppositely aligned cutter elements are mounted for displacement in a radial direction in a guide recess of a tool holder, and while in the operative position during the deburring of a bore, the cutting elements are displaced inwards radially because of the tool holder feed and because of the tapered extension of the cutting edges, against a spring force in the guide recess, until they finally reach the inner area of the bore in the non-cutting mode.
