Abstract: A positioning jig for locating drill holes or other targets in a workpiece on which the positioning jig is positioned. The positioning jig includes a pinion body and a pair of arms extending from the pinion body. The pair of arms are engaged with a pinion in the pinion body to provide a rack and pinion mechanism for centering the positioning jig on a workpiece. A jig body including at least one aperture is connected with the pinion body. The jig body may be translated with respect to the pinion body for locating the at least one aperture at a target point on the workpiece for drilling a hole or marking the workpiece.

Abstract: A novel method and instrumentation for insertion of humeral and glenoid total shoulder implant using arthroscopic visualization for bony preparation as well as insertion of components through small incisions. Mini instruments and cannulated guides and reamers are used in order to perform the procedure under direct arthroscopic visualization. For ease of insertion, the components are inserted separately and assembled in situ. Securing the humeral components in place is accomplished with bicortical screw transfixing the central peg of component.

Abstract: The present disclosure relates to a space and dimension determining device, which is useful for placement, mounting, hanging and leveling a picture, shelving, or any other object onto a receiving surface. The present device is capable of locking into position capturing the dimensions and allowing for “measureless” transfer of dimensions from one place to another. The present disclosure further relates to a device incorporating a laser, either as part of, or a separate, attachable feature to, the present device, the laser being useful for assisting in determining center points, and a plurality of dimensions and readings equal distance from the center point. The present disclosure also relates to a system and method of transferring dimensions from a space determining device to an electronic communication device, which is used to create a template for placement of an item or items within a target space.

Abstract: The present invention is a tool for locating and marking center points on various objects configured with a geared carriage assembly having guide holes for insertion of posts and a counterpunch centered automatically when posts are inserted into an interior and/or exterior surface of an object such as a square, rectangular, polygon, circle or other circular shapes. The tool is particularly novel to quickly and accurately locate the center point from a hole, aperture, and/or a prick mark made in the surface of the object such as, for example, paper, sheet metal, etc.

Abstract: The present invention is directed to a marking device that includes a main backplate. At the center of the marking device there may be a central hole, and attached to the backplate, are two extendable arms, each designed with a pin attachment to make marks and/or small holes in the wall material. The extendable arms are attached to the backplate in a manner that the arm pin attachments on each arm are perfectly aligned with the central hole. Using a set of gears or other method, the extendable arms are fitted to the back plate in a manner whereby the extension and/or retraction of one arm causes the other arm to move in an equal, but opposite manner. With this, the holes and/or marks will be equidistant from the central hole/pin hole, and also in-line with the center hole/pin hole and each other.

Abstract: A slider device (200, 800) according to the present invention includes a base (200); a running head (300) slidably provided on said base (200) along the direction guided by a prespecified guide mechanism (400); a rack (510) provided in the fixed state on either said base (200) or said running head (300) along the guide direction by said guide mechanism (400); a pinion (520) engaging with rack teeth of said rack and driven and rotated by a prespecified power source; a swing arm (540) rotatably supporting said pinion (520), having an oscillation shaft (550) parallel to a rotary shaft of said pinion, and coupled to either one of said base (200) and said running head (300) via said oscillation shaft (550) in the oscillation-allowable state with the line extending between said oscillation shaft (550) and the rotary shaft of said pinion substantially parallel to said rack (510) as the reference state; and a biasing mechanism (570) for biasing said pinion (520) toward said rack (510) via said swing arm (540).

Abstract: An instrument for measuring rigger-spread of a boat has an elongate casing 1 for support athwartships of the boat with a shoulder 2 of the casing 1 abutting the outside of the gunwale 4 opposite the rigger 5 and a slidingly-adjustable shoulder 6 abutting the opposite gunwale 9. A measuring tape 10 is extendable longitudinally from the casing 1 to the oarlock 14 of the rigger 5 to give a reading of spread, the extendable length being limited in dependence upon the spacing between the shoulders 2,6 of the casing 1 such that this length is increased or decreased by half the amount of any increase or decrease, respectively, of that spacing. Limitation of the extendable length involves a mechanism in which the two ends 18,19 of a flexible strip 15 or wire are secured respectively to the sliding shoulder 6 and the casing 1 so as to define a loop that is caught by a hook 16 of the tape 10 in limiting tape-extension.

Abstract: The center locator tool has a flat, rectangular case with a top wall, a bottom wall, and two opposing side walls. The interior of the case houses a spur gear rotatably mounted on a center post extending through the center of the case, the center post having a bore defined axially therein. A pair of arms are mounted so that the arms are slidable through the case on opposite sides of the spur gear, each arm having a rack defined in its edge which engages the spur gear so that when one arm is extended from the case, the other arm is extended an equal distance in the opposite direction. Each arm has a groove defined in its bottom surface for engaging a guide projecting from the bottom wall of the case. The end of each arm has a work engaging plate forming a "V" shape, the opening of the "V" facing towards the center of the tool, the plates depending from the ends of the arms and being adapted for engaging a square or circular workpiece.

Abstract: A jig-boring device, comprising an axle barrel which connects with bottom plate and is sheathed with lower gear, fixed support, upper gear and cover plate; a circular bottom plate connected to the bottom of the axle barrel; a lower gear placed on bottom plate sheathing the axle barrel; a fixed mount placed on lower gear sheathing the axle barrel; an upper gear placed on fixed support sheathing the axle barrel; a cover plate placed on upper gear sheathing the axle barrel; a lock nut which screws to the top outer periphery of the axle barrel; two pairs of measuring staffs which connect to two pairs of measuring staff brackets respectively; and two pairs of measuring staff brackets, placed symmetrizing each other on the bottom plate and fixed support respectively, which can measure out the abscissa and vertical coordinate of a desired bore center position about a work object.

Abstract: A self-centering jig for planar articles having a vertical and horizontal centerline, capable of centering in both the horizontal and vertical directions, is disclosed. The self-centering jig comprises a jig body a having a template section, a first pair of operatively connected arms extendibly mounted in the jig for uniform horizontal movement in opposite directions from a vertical centerline, and a second pair of operatively connected arms extendibly mounted in the jig body for uniform vertical movement in opposite directions from a horizontal centerline. The template section may be removable, and can be interchanged with other templates to permit drilling of different patterns using the same jig. The template section may also contain a plurality of holes for a plurality of patterns, such that a single template may be used to drill several patterns.
