Abstract: A non-indexable, one-sided cutting insert includes opposite insert side surfaces which define an insert width therebetween, opposite insert front and rear surfaces which extend between the insert side surfaces and define an insert depth therebetween and opposite insert top and bottom surfaces which extend between the insert side surfaces and the insert front and rear surfaces. The insert top and bottom surfaces define an insert height therebetween. The insert further includes a main cutting edge formed at an intersection between the insert top and front surfaces. A maximum value of the insert width is smaller than minimum value of the insert height, and a minimum value of the insert depth. The insert includes a deep opening which opens out only to the insert bottom surface and defines an opening depth. A depth ratio defined between the opening depth and the insert height is greater than 0.3.

Abstract: A saw blade with replaceable cutter teeth is provided. The saw blade is generally planer and has a first side and a second side, a leading edge and an inner edge. Plural cutting teeth members are removably secured at alternating spaced apart locations on the first side and the second side of the saw blade. Cutting teeth members have a cutting blade which extends outwardly from the leading edge. A variety of different ways to secure the cutting teeth onto the first side and the second side of the saw blade are disclosed.

Abstract: The disc saw blade has a plurality of arcuate teeth detachably mounted in complementary-shaped arcuate sockets provided in a rim portion around the circumference thereof. Each tooth has a portion butting against a stop, such as a transverse tail stop surface defined by an inward projection of the socket. The configuration provides a small throw entry gap to reduce the likelihood of sticks being thrown. The teeth preferably are detachably mounted by virtue of a tight fit within the sockets, with no use of fasteners to absorb cutting forces. Keying elements such as a male portion of generally rectangular cross-section extending from the socket into a corresponding female portion in the tooth preferably are used to ensure proper alignment of each tooth relative to the plane of the disc saw blade. Preferably, the teeth and sockets are parts of concentric circles, the diameter of the teeth preferably being slightly larger than the diameter of the sockets, thereby producing a press fit.

Abstract: A cutter tooth assembly for impingement of a material (e.g., a stump, wood, brush or earth strata). The assembly attaches to a driven member (e.g., a rotatable wheel). The assembly includes a cutter tooth which has an elongate body with a leading end and a trailing end, as well as a hard insert at the leading end of the tooth. The assembly also includes a pocket which has a base portion and a holder portion. The pocket attaches to the wheel at the base portion thereof. The cutter tooth is retained to the pocket at the holder portion thereof. The base portion of the pocket has a leading surface and a trailing surface. The cutter tooth is retained by the holder portion of the pocket so that the hard insert extends circumferentially past the leading surface of the base portion of the pocket.

Abstract: An indexable cut-off saw is used for cutting metal components, e.g. cutting a bearing cap cluster into separate caps. The saw has a circular tool body for mounting on an arbour and this tool body has flat side faces and a narrow outer periphery. A plurality of circumferentially equally spaced cutting inserts are mounted at the outer periphery of the tool body, these inserts being arranged in groups of three such that the total width of the saw cut is divided between the actions of three cooperating cutting inserts. These three cooperating cutting inserts include a central insert mounted centrally on the outer periphery of the tool body and left and right side inserts mounted in pockets extending into the side faces of the tool body. The left and right side inserts are of rectangular configuration presenting straight cutting edges, while the central cutting insert of each group presents a curving cutting face.

Abstract: In a cutting knife for rotary cutting apparatuses for paper, in particular multilayer separated paper products, having a circular base body, from the conical face of which opposite the cutting plane adjustable blades or the like project, the blades are arrested adjustably about a fulcrum or pivot point.

Abstract: A method and apparatus for cutting trees and bushes including a circular disk having cutting teeth connected thereto, a motor for rotating the disk and an arm connected to the motor for moving the disk into contact with trees and bushes.

Abstract: A circular disk carries individual saw chain teeth riveted in alternating fashion about opposite marginal sides of the disk. The disk is of lesser thickness than the kerf cut by the teeth. The preferred cutter blade includes teeth having a wide forwardly located depth gage inclined to the path of tooth travel.

Abstract: A circular saw blade in which tooth assemblies are pivotally mounted along the periphery of the disc spaced apart at equal angular distances. Each tooth assembly has a U-shaped tooth wedging member pivotally mounted on the disc. The tooth is secured between the disc and the wedging member. Pivotal movement of the tooth wedging member in one direction wedges the tooth between the disc and the tooth wedging member. Pivotal movement of the tooth wedging member in an opposite direction releases the tooth from the wedging action between the disc and the wedging member. A cam locking member is rotatably mounted on the disc adjacent the wedging member. Rotation of the cam locking member in one direction locks the tooth wedging member in the tooth wedging mode. Rotation of the cam locking member in an opposite direction unlocks the tooth wedging member to enable the tooth to be released from the wedging action between the disc and the tooth wedging member.

Abstract: A cutting knife for a rotary cutting apparatus for multilayer isolated paper products with projections, for example in tooth form, projecting from a base body. The projections are formed as blades or the like displaceable in or on the base body and inclined with respect to a cutting plane; the faces of the blades lying in the cutting plane can be reground.

Abstract: Wood-cutting apparatus with an insertable tooth in which the blade is positioned radially outwardly on a flat, elongated metallic plate and comprises two side edges, each of which: (a) extends generally radially (i.e parallel to a radius of the disc in which the tooth is inserted); and (b) is positioned ahead of the plate and other portions of the blade so that the side edges lead the tooth as the disc rotates in a predetermined rotational direction. The cutting edge of the blade extends along the most radially outward extent of a region of the blade connecting the two side edges, the connecting region being positioned rearwardly from those side edges in the rotational direction.

Abstract: The present invention is a rotary machining tool and a method of making it using an easily replaceable cutter element assembly. A circular saw is exemplary of a cutting tool which can be made using the present invention. The cutter element assembly comprises two portions. The first is an inverted, generally U-shaped clevis with spaced apart side portions that fit over the circumferential edge of a sawplate. The clevis has an upper portion which extends outwardly from the sawplate edge thereby defining a tooth retaining socket between the sawplate edge and the clevis. The side portions of the clevis are apertured to accept a pin for attachment to the sawplate which has a corresponding aperture. A buttress attached to the clevis normally bears against the leading edge of a gullet and prevents rearward rotation when in use. The second member is an insertable tooth having a head and an elongated tapered shank. The shank has a taper on its upper surface sufficient to form a self-releasing taper, usually between 3.

Abstract: An insertable tooth for use in a slasher for paper pulp manufacture is disclosed to have a flat elongated plate of steel of even thickness having a rounded base and substantially parallel leading and following edges with a V-shaped groove extending along a lower major portion of the leading and following edges. The tooth also has a planar top angularly extending from a lower point on the following edge toward a higher point near the leading edge. A blade of a material having a hardness of at least 9 MOHS is inserted in a notch at the high point of the leading edge. The blade is in the form of a cubic trapezoid, the base of which is arranged essentially flush with the leading edge. The width of the base of the blade is greater than the thickness of the plate of steel forming the tooth. The sides of the blade are relieved from the base while the upper surface of the blade is arranged nearly coplanarly with or slightly above the planar top of the tooth.

Abstract: A precision book cutting wheel with insertable cutting bits has sockets slidingly receiving the bits and a clamping block for holding the bit in adjusted position. The sockets are inclined at an angle of 20.degree. to 40.degree. to a cutting plane normal to the axis of the wheel, and each bit has an outer cutting edge formed by a bevel parallel to and adjustable to the cutting plane.
