Abstract: A deburring apparatus is provided for automatically deburring gears having a plurality of external or internal extending teeth formed therealong at predetermined intervals from each other. The apparatus comprises a frame having a spindle on which the gear to be deburred is mounted. A main shaft is rotatably supported within the frame which, upon rotation, incrementally indexes the gear mounted on the spindle for a distance corresponding to the distance between adjacent gear teeth and, after doing so, interrupts the rotation of the spindle for a predetermined period of time. Both an eccentric member and a cam are secured to the shaft. In addition a cutting tool arm is rotatably secured at one end to the eccentric member and, at its other end, a cutting tool is mounted. A bell crank is also pivotally secured to the frame and has a cam follower mounted to one end which engages the cam.

Abstract: A form relieving apparatus for providing axial and radial relief for a cutting tool such as a drilling or reaming bit, including a workpiece supporting carriage mounted for rectilinear movement in one of two perpendicular directions or in any direction therebetween and means for moving said supporting carriage a selected distance in a selected direction to move said cutting tool into and out of engagement with a grinding wheel.

Abstract: A windshield wiper attachment disclosed comprises an elongated wiper blade member and a carriage member including a pivot arm for supporting the blade member at a first end of the pivot arm. The attachment further comprises an adaptor assembly including a bracket pivotally connected to a second end of the pivot arm and an adaptor pivotally connected to the bracket, the adaptor being adapted for connection with a wiper arm member. When the adaptor is connected to an arm member, the adaptor, the arm member, the bracket, the first end of the pivot arm and the blade member are aligned.A second windshield wiper attachment also disclosed comprises the same elongated upper blade member and adaptor of the first windshield wiper attachment. A second carriage member of the second attachment includes a disk member for supporting the blade element by flanges integrally formed therewith at a position spaced from a central pivot axis.
