Abstract: A tool and method for plugging a service connection to a gas main in preparation for removal of the service tee removes the perforator, mills the hole in the main to provide a smooth seat for a sealing plug, and inserts a gas-tight sealing plug into the hole. The tool of the invention is operable through a narrow "keyhole" excavation, which decreases the risk to service personnel and significantly reduces costs of repairing the excavation. In the preferred embodiment the tool is loaded with a milling bit and a sealing plug before attachment to the service tee. The tool head is engaged to the service tee in a gas-tight fit to prevent the escape of gas during the procedure, and an adapter plate is pivoted between three working positions to perform the three steps of the service connection plugging method.

The cutter housing also has a channel for receiving a cutter, and the channel communicates with the recess for cutting a notch in the head of the rivet. A longitudinal axis of the channel is offset from a longitudinal axis of the rivet when the head of the rivet is positioned in the recess defined by the end portion of the cutter housing.

Abstract: A tool for preparing broken stud bolts or the like for extraction by screw extractors has a guide for centering a center punch and/or a drill on a broken face of a stud. The guide is a nut and a shaft assembly. The nut has a central bore therethrough having a first portion threaded to mate with the stud threads and a second portion bored to just slide over the stud threads. The shaft assembly has a cylindrical shaft having a first end and a second end and an axial bore therethrough. The shaft includes a first externally threaded portion extending from the shaft first end of threads similar to those of the broken stud and an expandable sleeve attached to the shaft second end such that threading movement of the nut toward the shaft second end axially compresses the sleeve whereby the sleeve expands radially outward. The second end of the shaft has a conical end face.

Abstract: A tool for removing broken threaded fasteners such as seized or damaged Budd nuts mounted on a stud extending from the hub of a dual wheel assembly. The tool includes a base plate which is securable at the Budd nuts adjacent the broken nut by stand-off and fasteners. A cutter is advanceable by a pivotal bar by means of a manually operable adjustment knob. The cutter is rotatable in a busing and has a cutting head with a bore which extends over the damaged nut. Replaceable cutting teeth are carried on the cutting head and when advanced cut through the flange on the damaged Budd nut. The device can be powered by a power tool attachable to the device. A depth guide is provided to assist the mechanic in correctly determining the proper depth of cut. As the cutting head is advanced, the flange portion of the Budd nut is cut away so the inner wheel rim can be removed from the hub and thereafter the remaining shaved Budd nut can be easily removed.

Abstract: A rivet remover has a casing with a rivet contacting region that is shaped for emplacement on a rivet head and has an interior passage that extends to that region. A rotatable drill bit carrier rod is movable along the passage to cause the bit to cut into the rivet head. The carrier rod may extend out of the casing to enable use of an electric drill motor to drive the tool. The rivet contacting region is on a casing end member which may be disengaged and replaced with any of a series of other end members that have differing rivet contacting regions adapted for conforming with rivet heads of differing sizes and/or shapes. The preferred embodiment uses an ordinary twist drill bit and apertures in the casing side wall discharge shavings that are drawn into the casing by the bit. An adjustable stop limits penetration of the bit into rivets to avoid damaging of the riveted structure.

Abstract: A tool to be used in cooperation with a rotatable drill having a shoulder portion and a shank portion to remove set rivets securing parts together. The tool includes a hollow compressible means which surrounds the drill. The compressible means is provided at one end with a relieved surface having a contour that mates with the head of the rivet and with a central bore through which passes the drill. Spacers may be provided between the shoulder portion of the drill and the tool as well as may be friction reducing. The drill is moved toward the head of the set rivet through the tool and into cutting engagement with the rivet head to cut away the central portion of the rivet head without inadvertent disengagement. The tool may then be removed from the drill to permit the rivet to be knocked out of the parts or the drill may then be used to drill out the remainder of the stem of the rivet.

Abstract: A water faucet valve removal and insertion tool includes a handle and a self-tapping threaded rod attached to the handle. There is a sleeve coaxial with the threaded rod and threadedly engaged therewith. The sleeve includes a rotational stop which is formed and adapted to interact with a water faucet valve. The threaded rod functions to form an internal thread in the stem of a water faucet valve to thereby attach the tool to the valve. The tool can be used to remove an installed water faucet valve or to insert a water faucet valve within a faucet housing. In either event the tool is attached to a water valve by the threaded rod and uses the rotational stop to turn an installed faucet valve or to turn a valve during insertion for proper alignment thereof.

Abstract: In a hand drilling tool, in particular for drilling out spot welds, comprising a bracing support means which is releasably mounted to the body of the drilling machine and which is displaceable in the direction of the drilling axis by way of an actuating lever which terminates in a handle, it is provided that the lever (4) acts on a fitment sleeve (6) which embraces the body (2) of the drilling machine and on which the bracing support means (3) is mounted and that the fitment sleeve (6) is adapted to be axially displaceable with respect to the body (2) of the drilling machine. To eliminate moments the axis of the lever which acts on the fitment sleeve intersects the axis of the body of the drilling machine.

Abstract: A device for removing a collar coaxially fixed to a projecting end of a fastener axially extending through the surface of a substrate, the device comprising a jig having opposed base and top surfaces and a cavity open at the base surface and disposed to coaxially receive the collar when the base surface is disposed on the substrate, at least one drill bit bushing extending through the jig on an axis generally parallel to and spaced a predetermined distance from the axis of the cavity, the bushing being disposed to guide a drill bit into engagement with the collar when disposed in the cavity, and an adjustable screw for controlling the axial length of drill bit extending through the bushing.

Abstract: A hand-held drill jig is utilized to locate and maintain a central axis through a head and an associated neck of a femur enabling a blind hole to be drilled into the femoral head oriented to the central axis. The drill jig is adjustable to accommodate a broad range of sizes of femurs and can be readily attached to, then removed from, the femur. A positioning mechanism is provided to firmly engage both the outer peripheral surface of the femoral head and the femoral neck. This operation renders associated drill bushing immobile relative to the femur and orients its longitudinal axis with the central axis. A drill bit is then capable of being guided through the drill bushing and into cutting engagement with the femoral head.

Abstract: A drill guide apparatus for use in drilling a central bore in a portion of a broken-off bolt remaining in a threaded bore. A clamp tube carries inwardly-directed setscrews for attaching the clamp tube to a stud or bolt located near the broken bolt. An arm extends adjustably through the clamp tube, and setscrews in the clamp tube hold the arm in a desired position relative to the clamp tube. A drill guide holder mountedon the arm includes setscrews which hold an appropriate drill guide tube in position to receive and guide a drill to bore the required hole in the remaining portion of the broken bolt.
