Abstract: In one aspect, a tool support for a pipe machining apparatus includes a support arm defining a groove therein and configured to support a tool, and a guide member at least partially positioned in the groove to allow movement of the support arm in a first direction and inhibit movement of the support arm in a second direction. In one aspect, a tool support includes a one-piece unitarily formed body member defining a cavity there through, and a tool support arm at least partially positioned in the cavity and configured to translate within the cavity. In one aspect, a tool support includes a first translating member configured to translate a tool toward and away from a pipe, and a second translating member configured to translate the tool toward and away from the pipe. The second translating member is coupled to and moveable relative to the first translating member.

Abstract: A joint prosthesis for mounting in a first bone and presenting a prosthetic joint surface for engaging an opposing joint surface of a second bone, the joint prosthesis comprising a sleeve which is adapted for partial disposition in an opening formed in the first bone; a center adapter which is adapted for disposition within the sleeve and a prosthetic joint surface mounted to the center? adapter; wherein the disposition of the center adapter is adjustable, both longitudinally and rotationally, relative to the sleeve, so that the disposition of the 15 prosthetic joint surface is adjustable, both longitudinally and rotationally, relative to the opposing joint surface of the second bone.

Abstract: An apparatus is provided that is configured for attachment to an aerosol can to permit mixing of contents therein. The apparatus includes a generally flat base portion coupled to a drive shaft orthogonally oriented relative to the base portion, and a securing strap attached to the base portion. The securing strap is configured to engage or grip a cylindrical end portion of an aerosol can to secure the aerosol can to the apparatus, whereby the drive shaft is configured to be mounted within a drill chuck to permit the mixing apparatus to rotate an aerosol can attached thereto for mixing contents within the aerosol can.

Abstract: A combination tool holder includes a holder body, at least one tool adapter and a bolt. The holder body defines therein a through hole including an enlarged-diameter segment, a reduced-diameter segment and a tapered segment. A stepped surface is formed between the enlarged-diameter segment and the reduced-diameter segment. The tool adapter defines therein a channel and has a combining end. The combining end has a conical surface configured to be received in the tapered segment. The bolt includes a screw and a nut. The nut is configured to abut against the stepped surface while the screw extends into the tapered segment to engage with the combining end. By screwing the bolt, the conical surface is driven to press against the tapered segment, making the through hole and the channel coaxial.

Abstract: An axially adjustable tool holder, having a principal body (1)with attachment, in a recess (2) of which is slidably mounted a mobile part (3) for mounting a tool (4). The mobile part (3) cooperates with a ring for transverse adjustment (5), mounted in rotation on the extremity of the principal body (1)with the recess (2) and secured transversely to said extremity, by a ball bearing device (8), in the form of a sleeve with an interior thread (5?). The ball bearing device (8) presenting axial play of the ring for transverse adjustment (5), when the mobile part (3) is tightened, application of the proximal face (51) of the adjustment ring (5)against a corresponding distal external supporting flange (1?) of the principal body (1). The mobile part (3) being locked in working position, after adjustment, by a device for tightening (6) by traction cooperating with a part (7) of the mobile part (3).

Abstract: A tool holder for a cutting tool having a tool shank includes a receptacle which extends in an axial direction and a sleeve disposed in the receptacle. The sleeve includes a tool receptacle structured to at least partially receive the tool shank and a blocking element that projects radially into the tool receptacle. The axial positioning of the sleeve is adjustable with respect to the receptacle.

Abstract: The invention relates to an adjusting device for axially supporting a shank tool in a shrink-fit chuck tool holder, comprising a leveling section on the side facing the shank tool to level out or at least reduce any changes in position and/or orientation of the shank tool which are due to shrinkage.

Abstract: The invention is a drill bit extender and method that enables holes to be formed or screws to be driven remote from a drill motor. It includes a drill adapter for attaching to a drill bit, hole saw, or spade bit, for example. The drill adapter accepts a threaded rod, such as a segment of rod that is threaded along its entire length, where the length of the rod determines the distance that a hole can be drilled remote from a drill motor. The rod is readily attachable and replaceable to enable an operator flexibility in drilling at various locations remote to a drill motor. The rod is attached to a drill motor by a drill motor adapter, which securely retains the rod in the drill motor adapter, enabling the drill motor to drive the remotely located drill bit efficiently.

Abstract: A micro-adjustable tool chuck comprises a first cylindrical body member (1) adapted for connection to a drive spindle, a second cylindrical body member (2) adapted to receive a tool bit in the end thereof, and moveable axially relative to the first body member (1), and means for drivingly connecting the first body member (1) to the second body member (2). A first screw thread (10) is formed on the outer surface of the first body member (1) and a second screw thread (11) is formed on the outer surface of the second body member (2). The first screw thread (10) is of a greater pitch (coarser) than the second screw thread (11).

Abstract: The adjustable-length tool holder for a rotating tool comprises a base element (7) which is provided with a coupling shank (9) for connecting to a machine tool and which, axially remote from the coupling shank (9), ends in a sleeve part (11) forming a central locating opening (13). The tool holder also comprises a plurality of tubular-cylindrical extension sleeves (15, 19) which in turn each form a central locating opening (17, 21) and of which a first extension sleeve (15) is arranged in an interference fit in the locating opening (13) of the sleeve part (11) in such a way that it can be positioned in an axially variable manner, and each of the further extension sleeves (19) is arranged in an interference fit in the locating opening (17) of the adjacent extension sleeve (15) toward the base element (7) in such a way that it can be positioned in an axially variable manner.

Abstract: A combination chamfering tool and cutting tool for a milling machine that machines a wall and leaves a chamfered comer including a shaft having one section (12) dimensioned to slip into a mill collet. Another larger cylindrical section (14) is joined end- to- end with the one section and has a conical end (16). A pair of cutting flutes (18) are formed on the conical surface (16). A central bore (20) extends the entire length of the shaft and is dimensioned to accept a mill cutter (22) slip fitted into the bore (20). A set screw (24) secures the cutter (34) in the bore (20). In one embodiment, a part of the bore is threaded and an allen screw (34) is a positioning stop for the cutter (22). In another embodiment, a cylindrical sleeve is journalled onto the shaft forming a chamber.
