Abstract: The organizer glide system of the present invention is comprised of a base frame slidably engaging a pair of support rails mounted to a support surface. A wire basket or other organizer container is removably secured to the base frame. The glide system is designed so that the application of external pressure, such as is generated by a heavy object held within the organizer, creates tension on the leg members of the base frame; thereby flexing the leg members resulting in a trussing effect by the side runners against the channel walls to control the sliding movement of the base frame and container. Interaction of the stop member of the base frame with the stops of the support rails limits the reciprocating movement of the glide system.

Abstract: The shelf connector of the present invention forms a single bracket for the attachment of shelves to a support frame. The shelf connector can be manufactured from either metal or plastic and adapted for installation on either round or square tubing. The shelf connector of the claimed invention facilitates attachment of shelves to a support frame with the shelf lip in the "up" or "down" position. The shelf connectors may be installed on either the left hand side, right hand side, or centrally located with respect to the support member. After installation, the shelf connector covers the ends of shelves to provide a finished, decorative appearance.

Abstract: A blast joint for use with a snubbing unit includes a casing around the protective rings and means for sealing around the bottom of the rings between the tubing and the casing.

Abstract: A multiple saw blade adjustable dado cutter assembly. The cutter can be used with a table saw or a radial arm saw, for example, to make dado cuts in board lumber. A pair of cooperating cams, each connected to a saw blade, can be adjusted to make a dado cut of a desired width. If the desired dado width is wider than the two blade configuration can cut, a center cam attached to another blade can be inserted between the pair of cooperating cams. With the three blade configuration, the three cams cooperate to allow the three blades to be spaced for the desired width of cut. In both configurations and at any spacing width, the two or three blades employed remain in a generally parallel alignment and transverse to the axis of the arbor on which the assembly is secured. To permit the blades to function with this geometrical relationship and to be adjustable, not all of the blade teeth lie in the same plane. The sequentially operating three or more cam assembly has uses beyond dado cutting.

Abstract: The present invention comprises a wood bit for use in wood working applications. The blade of the bit is generally spade shaped having cutting spurs on each corner of the blade, a central point projecting from the leading end of the blade, and hooked cutting edges.A progressive transfer die is used to bend the leading end of the blade and forge a continuous hook angle extending along the side cutting spur, the lateral shoulder, and the central point of the blade. The forging of a hook extending from each side of the blade converging at a central point provides a hook along the leading end of the blade projecting outwardly (in the direction of rotation) pass the plane of the blade face. The leading end of the hook is beveled forming a continuous cutting edge extending along the hook from the outer side wall of the blade through the outside cutting spurs, along the lateral shoulders, and along each side of the central point.

Abstract: A router accessory used in concert with a router attached to a router table. The accessory can be used to produce rosettes, model wheels, buttons, coasters, and other circular decorated projects, for example. In the preferred embodiment, a wooden workpiece can be positioned horizontally above a selected router bit. The workpiece zero point, which may be the workpiece center, can be off-set horizontally from the router bit. The accessory can then be used to lower the workpiece onto the router bit, so that rotation of the workpiece routs a circular cut equidistant from the workpiece zero point. The maximum depth of cut can be set. The off-set can be changed to make additional circular cuts into the workpiece, as desired.

Abstract: A drill bit includes an elongated shaft with a threaded male end and a cutting head with an axial through-bore having female threads to receive the male end of said shaft in threaded engagement, and there is a bearing surface area between the shaft and the cutting head above the threaded portion which provides for proper alignment and reduced stresses.

Abstract: A drill bit for drilling holes around the corner of a workpiece is provided with a single rounded continuous cutting edge with radiused upper and lower corners to permit free rotation of the cutting head as it is urged along an arcuate path. The bit is of a unique two piece construction permitting selective materials to be utilized in the shank an cutting head portions.

Abstract: A hard, relatively non-brittle, cemented carbide body is made by sintering pressed grade carbide powders in the presence of a boron-containing material such as boron nitride. During sintering, appreciable quantities of boron migrate or diffuse into the body to become incorporated throughout the microstructure of the carbide resulting in the formation of a third quarternary phase comprised of tungsten, nickel, boron and carbon.

Abstract: A router attachment which is particularly useful for cutting decorative slots or grooves in wood and/or other materials, particularly those decorative cuts that are present in dentil moulding(s).
