Abstract: A hole tapping device having a motor driven tapping tool with a bracing frame for resisting reverse torque on the motor frame caused by resistance of the rotation of the tapping tool within a bore being tapped. The bracing frame has adjustable arms which provide adjustment in the radial and angular direction and which clamp stationary protrusions on the workpiece with rollers to hold the bracing frame against rotation in both directions about the axis of the bore. The adjustments of the frame provide great geometric versatility. The rollers provide for a smooth translation of the motor and bracing frame along the axis of the bore being tapped. A single coupler and a series of inserts allow for a series of differently sized tap tools to be driven through the use of a single coupler.

Abstract: An apparatus for positioning a bowling ball during a drilling process and method that provides reproducible orientations of the ball for accurately modifying and repeating the drilling process is described. The apparatus affixed a bowling ball while exposing a sufficient portion of a surface of the ball where middle finger, ring finger and thumb holes are to be drilled. The apparatus positions the bowling ball for drilling holes of varying pitch without requiring the ball to be removed from its rigidly affixed position within the apparatus. Holes having severe pitches are easily drilled and reproduced, including oval holes having preselected oval rotations. A computer program converts inputted hand measurements to digitized apparatus movements for positioning the ball prior to drilling a desired hole. Digital encoders indicate apparatus movement that is matched with computer output for ease and repeatability in drilling a ball.

Abstract: A milling and drilling unit utilizes a stiff arm and a articulated arm, both arms being supported on an upright post and each being fitted with a clamping member that is capable of engaging bodies of substantial cross-sectional variation. The arms can be raised and lowered on a rack, using a meshing pinion that is operated from either side of the unit, and they are capable of rotation about the supporting post when lowered sufficiently to disengage the rack-and-pinion mechanism; clamping levers serve to fix the arms in selected vertical positions.

Abstract: An apparatus for countersinking rivet holes preformed at circumferential spacings in the fuselage of an airplane and in annular reinforcing ribs of H-shaped cross section in the fuselage at axial spacings. Included is a carrier arm cantilevered to a frame for insertion in the fuselage and reinforcing ribs. The carrier arm has a fluid-actuated cylinder and a fluid motor. The cylinder has a piston rod to which is coupled an offset anvil assembly for pressing the fuselage and a rib against a toolhead mounted to the frame. The piston rod, together with the anvil assembly thereon, is not only linearly displaceable but also rotatable about its own axis. The fluid motor actuates the piston rod for revolving the anvil assembly through an angle of at least 180 degrees. With such angular displacement of the anvil assembly, the apparatus is readily adaptable for countersinking two annular rows of rivet holes formed in those parts of the outer flange of each rib which are on the opposite sides of its web.

Abstract: An improved work-supporting table particularly adapted for shiftable mounting on the support column of a drill press is provided which permits the reciprocable drill bit to cut through the entire thickness of workpiece material supported on the table surface without defacement of the latter irrespective of the drill bit position relative to the table. An arcuate groove in the table surface directly below the drill bit extends parallel to the swinging path of travel of the table relative to the drill bit and provides clearance for the bit when the latter is reciprocably advanced to the table surface. The recessed surface of the groove is covered by a strip of hardened material which is resistant to the cutting action of the drill bit thereby protecting the groove against inadvertent defacement by engagement with the bit.
