Abstract: An apparatus for drilling matching dowel holes in at least two companion workpieces includes a frame with a top surface and a drilling mechanism driven by a motor. The drilling mechanism is slidably attached to the top surface of the frame and movable along a first drilling axis substantially parallel to the top surface. A centering mechanism automatically centers the workpieces with respect to the first axis by movement along a second axis. A positioning mechanism is rigidly attached to the centering mechanism and positions the centering mechanism such that each of the workpieces is positioned in at least two dowel hole drilling positions along the first drilling axis. The positioning mechanism includes spaced-apart first and second stop members which define first and second dowel hole drilling positions. A stop engaging member is positioned movably between the first and second stop members and rigidly connects the positioning mechanism with the centering mechanism.

Abstract: A tool jig for bringing an implement to bear on an inner tubular 10 of a multi-tubular blown well includes a support 1 attachable to the outer tubular 2 and a tool holder 12. The tool holder has a hollow bore and a valve 24. At its rear end the tool holder is threaded for coupling on an implement and has at its front end a saddle seal for sealing the implement with the inner tubular, via through a window 9 in outer tubular 2. A back-up unit 18 abuts the inner tubular opposite the tool holder 12. The support 1 supports the tool holder 12 and back-up unit 18 via connecting brackets 13, 19. Screw jacks 22 acting through the support clamp the tool holder and backup unit in position.

Abstract: A door lock drill assembly includes a housing with an apertured side wall and end wall, securable upon the upright edge of a door for drilling a first aperture through the door on a first axis and successively drilling a second aperture into the door edge on second axis coplanar to and at right angles to the first axis. Guides are mounted upon the side wall and end wall and extend at right angles thereto. A hole saw is reciprocally mounted upon one guide coincident with the first axis, and includes a projecting coaxial drill shaft. A drill bit is reciprocally mounted upon the other guide coincident with the second axis, and includes a projecting coaxial drill shaft. The drill shafts are adapted to be selectively and alternately power driven and fed into the door by the application thereto of a power driven tool.

Abstract: A jig for guiding the bits of boring and routing tools to predetermined locations on a door in preparation for the installation of a door knob assembly, dead bolt or the like. The apparatus includes an elongated channel-shaped frame member for receiving an edge of a door and having a base portion and two depending side portions, a pair of templates attached to respective side portions of the channel shaped frame member for guiding a boring tool bit to locations along the side of the door, a movable edge boring guide attached over the base portion of the frame for directing a boring tool to predetermined locations along the edge of the door, and a pair of clamps for clamping the frame firmly to the door. The base portion of the frame forms a router support surface to facilitate routing of the edge of the door.

Abstract: A door boring jig system for aligning a cross bore and edge hole in a door, including a pair of spaced clamping jaws; a bore hole in one clamping jaw locating the position of the cross bore; adjustment means for moving the clamping jaws toward and away from each other to adjust to the width of a door to be bored; a bushing mounting hole in the other clamping jaw aligned with the first bore hole; a split bushing having a flange at one end and a hinge at each end, each hinge including a pair of pins mounted in separate parts of the split bushing and a link pivotably mounted to both pins; each link being loosely fitted to at least one of the pins to enable the bushing parts to slide or translate as well as pivot or rotate relative to each other; guide means mounted between the clamping jaws remote from the first hole and bushing mounting hole and having an edge hole guide for defining the position of the edge hole; and edge bevel accommodator means including first and second mounting means carried by the guide m

Abstract: The spectacle frame includes a frontal lens support incorporating a nose bridge, a pair of temples, and hinges connecting each temple to an outer end of the lens support. A blind bore is formed in either the lens support or the temple at at least one outer end of the lens support. An adjustment mechanism, including an internally threaded sleeve and an externally threaded adjusting rotor member, is inserted in each bore. The adjusting rotor member has an outer end engaging the other of the lens support and the temple. The adjusting mechanism is formed with a notched or knurled operating head particularly configured for operative association with assembling tools.

Abstract: A support device for a pipe driller and particularly for sewer pipe which eliminates excavation from the underside of the pipe. A support means engages a standard pipe driller and arm members extend from the support. The arm members are pivotally secured to the support and extend in one direction to partially surround the pipe. The arm members also extend in the opposite direction and are operable with screw means to secure the opposing arms against the pipe. The pipe contacting portions of the arm are preferably arcuate in configuration and surround the pipe over not more than ninety degrees of its radius and above the lowermost portion of the pipe.

Abstract: A clamp, useful in mounting a drill jig having a base plate with drill guides on a ski for boring holes for bindings, comprising a pair of jaws having face portions and mountable on the base plate, the jaws being moveable with respect to the base plate and the face portions opposing each other, means for biasing the jaws toward a first closed position, and manually operable means for overcoming the biasing means to move the jaws to a second open position. In a preferred embodiment the jaws have rack portions engageable with a pinion rotatable with the manually operable means, at least one of the faces has an adjustable stop for centering the jig on the ski, and a torsion spring contained within the manually operable means provides the biasing means.
