Abstract: A diamond point type dressing tool with means for adjustment to dead center within a tolerance of .+-.0.0001" is mounted to a control head assembly capable of producing horizontal, rotary and vertical movements of the tool either independently or simultaneously to reproduce from a remotely disposed associated template any desired contour of angles and radii on the peripheral edge of a grinding wheel. A tracing rod, snugly but slidably journalled through a support ball, has a tracing end adapted for manual movement over the profile of the template and a control end operatively associated with the control head for reproducing the template profile in the movement of the dressing tool and for rotating the diamond point where necessary on the profile. The ball support is seated in the control head and is fixed against lateral or vertical movement but has the capablility of turning in place as the orientation of the axis of the rod is changed during movement over the profile.

Abstract: A boring tool is disclosed capable of positioning a tool element between a radial cutting position and a radial retracted position out of contact with the finished workpiece bore to avoid tool mark formation on the finished bore during tool withdrawal. The boring tool is simple and low cost in construction and includes a resilient tool-carrying member which extends transversely of the spindle axis in cantilever fashion for deflection by a spindle draw bar relative to a stop means on a fixed support member attachable to the spindle. During boring, the tool-carrying member is in deflecting engagement with the drawbar and, in conjunction with stop means, positions the tool thereon in a radial cutting position. For tool withdrawal, deflecting engagement is released so that the resiliency of the tool-carrying member positions the tool in a radial retracted position out of contact with the finished workpiece bore.

Abstract: A plate glass repair apparatus comprises a plate member that has an outer peripheral seal and can be held onto the surface of the plate glass to be repaired with vacuum generated from a self contained hand operated vacuum pump mounted on the plate.

Abstract: A boring tool assembly performs both the rough and finish cutting operations upon a metal work piece without power activation or manual adjustments of the tool units between the cutting strokes. The assembly includes a boring bar having a pair of fixed, diametrically opposed rough cut tool units, and a pair of retractable finish tool units diametrically opposed to each other also. The tool units are automatically operative in response to either the rough cut or the finish cut of the boring tool assembly. Spring biased plungers normally pivot the finish cutting units toward their cutting positions. During the initial or rough cutting operation, forces act upon the heel of the finish tools causing retraction from the cutting position. This is possible due to the cutting edge configuration and angle of orientation of the tools, the positioning of the tools on the trailing side of the boring bar centerline, and the direction of advancement of the boring bar.

Abstract: A combination extension and compression tool holder having a cylindrical outer housing adapted to be inserted into a chuck of a rotary drive machine. A tool holding rod is axially slidably mounted in a cylindrical recess formed in the housing for rotation about its axis of elongation. Two opposing helical springs are disposed within the cylindrical recess and bias the tool holding rod towards an intermediate position within the cylindrical recess. During the feed-in of the machine chuck during a deburring operation, one of the helical springs can be compressed to permit the deburring tool to be retracted when the deburring tool engages an unfinished hole resulting from drill breakage to thereby prevent the deburring tool from being forced into the unfinished hole and thereby broken. During the deburring operation of a normally formed hole, the compression spring will permit the deburring tool to dwell at the opening of the hole for a better deburring operation.

Abstract: A cylindrical deburring tool is provided with a diametric guide slot extending through the body with a pair of cutter blades received in said guide slot for radial displacement therein and spring-biased apart to a position determined by an adjustable abutment means acting on each blade.

Abstract: A compression tool holder for use with deburring tools or the like, the tool holder having a cylindrical outer housing adapted to be inserted into a chuck of a rotary drive machine. A tool holding rod is axially slidably mounted in a cylindrical recess formed in the tool holder. A spring loaded piston is mounted behind the rod and urges the rod to its extended position. A cap member, however, defines the limit of the extended position for the rod. The rod has an outside diameter somewhat smaller than the inside diameter of the cylindrical recess in the tool holder so that the rod may compensate for misalignment by pivoting relative to the housing within the cylindrical bore, utilizing the cap member as the fulcrum point for its pivot. The end surface of the piston coacts with the end surface of the tool holding rod so as to return the tool holding rod to a central aligned position when misalignment compensation is not required.
