Abstract: An apparatus and method for imparting a sharp, defect-free outside corner of a desired angle to a metal workpiece are disclosed. The apparatus comprises two separate cutting tools, each with a distinct cutting direction. The tools are juxtaposed such that their leading surfaces are adjacent to each other and that their respective cutting edges intersect at the desired angle. This provides that the cutting directions of each tool are opposite one another. In using the improved cutting apparatus, the workpiece is secured and the apparatus must be movable along the x, y and z axes. By cutting the first and second surfaces of the workpiece in sequence with the first and second cutting edges of the present apparatus respectively, a sharp defect-free corner of the desired angle can be imparted to the workpiece. A specific application for the present invention is in the fabrication of intricate copper products, such as heatsinks for semiconductor devices.

The cutter is directed along a curve of the inner edges of the bore of the workpiece by a cam on the frame engaged by a follower on the cutter spindle.

Abstract: A hand tapping device has a driving rod at one end provided with a handle and a chuck at the other end for holding a tap. A housing located between the rod and chuck is attached at one end to the rod for axial movement and at the other end to the chuck. A sleeve attached to the rod provides a guide for axial movement of the housing in response to rotation of the rod to effect cutting threads by the tap as the housing expands from the rod and sleeve with a progressively reducing force exerted by a spring located within the housing. At the same time, a graduated scale on the outer surface of the housing indicates the distance the housing moves outwardly from the sleeve and the corresponding depth of the tapped threads.

Abstract: A rod chucking device for a perforator for perforating a pig iron discharge opening being adapted to mount exchangeably perforating rods for perforation work, such as drill rods, blanking rods and the like to the tip end of an impact rod. The chucking device has a cotter movable between an engage position and disengage position in order to fix the perforating rod inserted into a rod insert hole of a socket. A spring is engaged with the cotter for urging the cotter toward the engage position. In order to prevent deterioration of the spring through vibration and heat during the operation, chilling air passage from the impact rod to the perforating rod is separated to form an air passage to chill the spring.

Abstract: A radially expansible thin-walled expansion sleeve (13) is expansible under hydraulic pressure by pressing a piston element (17) against hydraulic fluid in a chamber, upon operation of a threaded bolt (18) in a threaded bore (19) in the spindle (11) or an attachment element (12) connected thereto. To prevent loss of the grinding disk, and provide a safety interlock in case of leakage of hydraulic fluid and hence loss of frictional engagement due to the expansion sleeve, a safety lock is formed by a sleeve element (22) which has resilient tines (24) extending therefrom, formed with locking projections (25), radially expanded behind a shoulder (30) formed on a disk holding bushing (1) upon tightening of the bolt (18). The tines (24) have internal camming surfaces (26) which engage against conical surfaces (27) located on the spindle (11) or the attachment (12) thereto.

The edges (13,16) are preceded in the rotational direction by a third cutting edge (14) which during the drilling cuts away the material radially inside a circular groove which is cut by the first and the second cutting edges (13,16).

Abstract: A quick changing jaw carrier assembly for mounting a top jaw. The jaw carrier assembly includes a main jaw carrier slidably confined for radial movement within a slot of a rotatable housing. An auxiliary jaw carrier or locking wedge is radially slidably mounted on the main jaw carrier. The auxiliary and main jaw carriers define radially opposed wedges for defining a dovetail structure which lockingly engages a similar such structure on the top jaw. The auxiliary jaw carrier is spring urged outwardly into a jaw-engaging position, and can be manually moved inwardly from this position when release of the jaw is desired. A manually-controlled locking cam is rotatably supported on the main jaw carrier and can be rotatably displaced into a locking position wherein the locking cam projects radially beneath a shoulder formed on the auxiliary jaw carrier when the latter is in its jaw-engaging position.

Each jaw is substantially symmetrical to a respective jaw plane extending substantially radially of the chuck axis. In addition each jaw is formed with a pair of angularly spaced teeth substantially symmetrically flanking the respective jaw plane and each having a respective inwardly directed edge and an outer tooth surface extending radially back therefrom and angularly away from the respective jaw plane.

Abstract: A dust guard cap for the tool holder in a hand-held drilling device is formed of a casing secured on the tool holder and a cover member mounted on and extending across one end of the casing. The cover member forms an opening through which a tool can be inserted into the tool holder. Attached to the cover member and extending inwardly from the through opening is a resilient sleeve-like torus which forms a seal around the tool. An outwardly projecting bead is formed on the inner end of the torus and bears against the casing.

Abstract: In a drill chuck for securing the shank of a tool in a hand-held device, clamping jaws are mounted in a chuck member and bear radially outwardly against the conically shaped surface in a first sleeve into which the tool shank is inserted. A second sleeve is connected to the first sleeve and is threaded engagement with the chuck member. A locking or third sleeve is located about the first and second sleeves. The third sleeve is axially displaceable between a first position and a second position. In the first position the third sleeve engages the first and second sleeves so that the second sleeve cannot be rotated relative to the first sleeve or the chuck member and the tool shank can be locked by the clamping jaws. When the third sleeve is displaced into the second position, the second sleeve is released and can be rotated relative to the chuck member for axially displacing the first sleeve relative to the chuck member and adjusting the radial position of the clamping jaws.

The projections may be joined through an external annular ring which encircles the hole saw. The ring may be grasped and forced downwardly causing the plug member to eject a waste plug from the hole saw. A spring may be positioned between a mandrel of the hole saw and the plug member in order to normally bias a plug member downwardly to assist its positioning and ejectment of a waste plug.

Abstract: An axial lead forming machine is presented which is capable of trimming, shaping, and electrically verifying the characteristics of axial components under computer control. Two die cutting and bending assemblies are incrementally moved horizontally over the wire leads of an axial component, which is suspended between them. A set of counters, lead screws, and two electric motors initially hold the two die assemblies in a known position defined as a "home" location. By correlating the number of leads per inch on the lead screws and counting the number of rotations of the electric motor, the lead forming mechanism is capable of communicating to a computer the exact location of the hammer, anvil and cutting edge of the die assemblies so that a programmable setting of the trimming and shaping of the axial leads may be accomplished automatically under computer direction.

Abstract: A boring tool with interchangeable tool bit holders is equipped with weight balancing members pivotable about a common fulcrum located on the rotation axis of the fine boring head. The weight balancing members are in the form of circular segments. They are pivoted from their given position about the common fulcrum by means of pull cords fixed thereto. In principle, each pull cord is fixed to each weight balancing member. Thus, a first pull cord fixed to one side of two weight balancing members is guided about a first guide bolt and a second pull cord fixed to the other side of the two weight balancing members is guided about a second guide bolt.
