Abstract: An arbor apparatus for mounting an attachment to a rotary tool includes a mandrel with a drive stage insertable into a passage in a drive boss such that rotation of the mandrel rotates the boss. The boss has a polygonal drive head engageable with the drive opening of the attachment. One end of the mandrel has a locking plate that approaches the drive head when the mandrel is inserted into the boss. The locking plate is sized to pass through the drive opening while also partially extending radially beyond the edge of the drive head. With the mandrel inserted through the boss, the locking plate is passed through the drive opening of the attachment. With a gap being maintained between the locking plate and the drive head, the mandrel is manually rotated to allow the drive head to enter the drive opening, simultaneously causing portions of the locking plate to extend beyond the edges of the drive opening.

Abstract: A manually tightened drill chuck includes a drill body, a nut, a front sleeve and a rear sleeve. The front sleeve is provided on the front end of the drill body with the nut being provided in the middle. A decorative sleeve is mounted on the front end of the drill body with an external peripheral surface of the nut being housed in an inner sleeve by shrink fit. At least one key groove is located in the inner wall of the front sleeve. A key cooperates with the key groove. At least one locating member is provided in the lower end of the key that includes a hole. The front sleeve further defines at least one protrusion that corresponds to the position of the hole for snapping into the hole. Accordingly, the stability of the front sleeve and the rear sleeve without radial vibration is achieved.

Abstract: A tapping device is configured to be used within a drill press or lathe or other device capable of holding a cylindrical object. The tapping device has an upper projection for being axially fixed in, for example, a drill press. The remainder of the body of the tapping device is rotatable with respect to the upper projection and includes side handles for providing handy mechanical advantage to the turning of the tapping device body. The end of the body opposite the upper projection includes a chuck for holding a typical tapping tool. The projection is connected to an internal shaft which engages the body of the tapping tool and is spring biased to draw the projection and internal shaft within the body of the tapping tool. Conversely, when the tapping tool is supported in, as an example, a drill press chuck, such spring urging acts to lift the body of the tapping tool in the direction of the projection.

Abstract: Collet chucks (20) comprise at least two tensioning segments (21). Adjacent tensioning segments are connected to each other by way of elastic spacer elements (30). The tensioning segments (21) have back-cuts (22), whilst the spacer elements have correspondingly formed sections (36). A positive fit of the formed sections in the back-cuts of the tensioning segments (21) is thus possible.

Abstract: Apparatus for releasable attachment to an electric drill housing includes a flexible base member, a bit holder and a flashlight. The positions of the bit holder and the flashlight are adjustable relative to the base member and a flashlight head of the flashlight can be adjusted relative to the flashlight body.

Abstract: A weight and method of providing mass for a model racing car is the subject of the present application. The weight is comprised of two portions. The first portion simulates the undercarriage of an automobile and the second portion comprises multiple components joined by lines of weakness. The multiple components of the second portion can be broken away to vary the total mass of the weight. The method comprises forming a weight having a first component of the configuration of an automobile undercarriage and a second component comprised of a plurality of sections joined by lines of weakness and the step of attaching the weight to the bottom of a model racing car. Portions of one of the components may be removed to vary the total mass.

Abstract: An adapter for prompt engagement a shank of screw driver with a handle includes a tubular adapter connected with a handle, a polygonal central bore having a reduced bottom, a concaved front outer periphery to define a shoulder thereunder, a plurality of conical through holes around a middle peripheral wall for respectively disposing a plurality of steel balls, a conical spring disposed into the central bore having a large thick upper portion blocking the conical through holes and a small incompact lower portion fixed in the reduced bottom, an annular sleeve with an annular convex on middle inner periphery slidably wrapped on the adapter biased by a circular spring on the shoulder, an annular cap fixed on the top of the adapter with a circular ring engaged therebetween, a receiving space for receiving the steel balls and a polygonal shank of in the bore is held by the steel balls.

Abstract: A sheet metal hole cutter has a cap plate defining a substantially circular peripheral groove and an annular shelf extending radially outwardly from the peripheral groove. An elongated band forming an approximately circular shape with opposite ends of the band contacting each other defines a base edge received within the circular peripheral groove in an abutting relationship with an inner edge of the groove. The band defines an axial depth of about ½ of an inch or less, and an outer diameter within the range of about 9/16 of an inch through about 6 inches. A weld region fixedly secures the base edge of the band to the cap plate. The annular shelf of the cap plate extends radially outwardly from the base edge of the band and defines a radial depth of at least approximately 1/16 of an inch in order to prevent over-feeding of the hole cutter through a work piece.

Abstract: This invention is a long thin rocket that launches forward and glides backward after an ejection pitch maneuver with no moving parts. It takes advantage of a shift in center of pressure caused by a change in the angle of incidence of the rocket. This change in angle of incidence is caused by the side thrust pitch maneuver. The pitch maneuver is initiated by the ejection charge out a side thrust port or other side thrusting apparatus at a location on the rocket causing a large torque about the center of gravity of the rocket. The center of gravity of the rocket after the pitch is optimally less than 60% of the way between the Barrowman center of pressure and the center of lateral area center of pressure.

Abstract: A tool for machining workpieces, having a parent body which can be expanded at least zonally, having at least one geometrically defined cutting edge projecting beyond a circumferential surface of the tool, and having a setting device influencing the radial distance of the cutting edge from the center axis of the tool. The setting device has a setting element, and an adjusting device which sets the degree of bending of the setting element. The setting element is inserted into the parent body of the tool in such a way that, when the bending of the setting element is varied, the radial distance of the cutting edge is varied.

Abstract: A central piece of a drill guide is formed by a pair of opposing boards having elongated slots formed therein. A second pair of boards similar to the first set also has elongated angulated slots formed therein.
