摘要： A method of making a shock-resistant and wear-resistant composite steel tool comprises providing a steel tool body having a working edge, and providing a working part material of nonporous wrought steel in an unhardened state which is hardenable to a hardness greater than that of the body. The working part material, in its unhardened state, is fused by welding to the working edge of the tool body while being pressed forcibly against the working edge. After the fusion step, the outer surface of the working part material is hardened to a hardness greater than that of the body of the tool, the depth of penetration of such hardening being limited to the region immediately adjoining the outer surface of the material so that the underlying region of the working part remains ductile, and the weld is normalized thereby increasing its ductility and resultant shock resistance. The method is adaptable for economical high production of saw blades, cutting bits, and other tools of composite steel structure having hardened cutting tips or other hardened working parts.

摘要： An adjustable wobble dado assembly has a planar circular blade with spaced peripheral cutting teeth. The cutting teeth have respective top cutting edges at their radially outer extremities which are located at progressively different radial distances from the axis of the blade so that, when the axis is tilted relative to the arbor for purposes of cutting a groove, those top cutting edges located at progressively greater radial distances from the axis cut portions of the groove located progressively further from the longitudinal center of the groove. The top cutting edges also have respective different top angles relative to the axis of the blade, those edges located at progressively greater radial distances from the axis having progressively greater top angles relative to the axis. An adjustable hub assembly includes a hub composed of an integral portion of the material of the blade having a thickness greater than that of the blade. The hub protrudes axially in opposite directions from the blade and terminates in parallel planar outer surfaces facing opposite to each other and inclined with respect to the axis of the blade.

摘要： Wear-resistant and shock-resistant tools are constructed by preforming carbide-containing working parts of high wear resistance and hardness and attaching them to a softer base metal of the tool by means of a highly shock-resistant steel-to-steel fusion weld. The working part is preformed by powdered metallurgy techniques utilizing steel powders having carbide-forming constituents therein which form carbides along the grain boundaries of the steel uniformly throughout the working part as a result of sintering of the compressed powders. Thereafter the fusion welding process renders the carbide structure of the working part nonuniform for optimum shock resistance, without reducing the effective wear resistance thereof, while also forming a highly shock-resistance joint between the working part and the base metal of the tool.

摘要： An adjustable wobble dado assembly having a plate-like circular blade, a pair of inner plate members fixedly mounted on either side of the blade having generally parallel outer surfaces and complementary inner surfaces for holding the blade at an inclined position relative to the outer surfaces, and a pair of interconnected outer plate members on either side of the inner plate members having parallel outer surfaces and complementary inner surfaces inclined relative to the outer surfaces and bearing rotatably against the inner plate members. Each inner plate member has an inwardly tapering central aperture for rotatably receiving a respective cylindrical hub of an outer plate member. Each cylindrical hub extends along an axis perpendicular to the outer surface, rather than the inclined inner surface, of the outer plate member, such axis also being coincident with the axis of an arbor bore extending through the hub. The outside surfaces of the hubs, if tapered at all, are not tapered to the same degree as the central bores of the inner plate members, so that upon relative rotation of the blade and inner plate members relative to the outer plate members, the central bores tilt with respect to the hubs as though moving about a fulcrum. The inner and outer plate members are formed of a material having a greater specific gravity than the material of the circular blade so as to maximize the concentration of mass near to the arbor axis of rotation.

摘要： An apparatus for rapidly manufacturing elongate sawblades, such as saber sawblades, from a continuous band of metal. All sequential steps of the manufacturing operation, including tooth-cutting, deburring, tooth-setting and shank-forming are performed prior to the blade being severed from the band of metal so as to avoid the necessity of handling the individual blades separately for any of these operations. All operations are synchronized to the movement of the tooth cutter, the speed of which is maximized by advancing it in a direction perpendicular to the width dimension of the steel band. The outer surface of the tooth portion of each sawblade is heat-treated to provide hardness, but hardening and resultant brittleness of both the core metal of the tooth portion and the entire shank portion of the blade are avoided to preserve their ductility and resistance to breaking. High frequency electrical induction heating of a discrete portion, rather than the entirety, of each blade enables the attainment of these objectives.
