Abstract
208,812. Kane, R. W. H., and Badcock, F. Oct.< >2, 1922. Chucks.-A device for holding circular articles, such as the liners of bearings, while being bored comprises a housing subdivided longitudinally and provided with means for retaining an easily renewable lining in each section of the housing. The section A, Fig. 1, is slidably mounted on a bracket D secured to a boring-machine or lathe face-plate so that it can be adjusted in a plane perpendicular to the axis of rotation, and carries a cap B secured by bolts. A register line V, scribed on the bracket and housing serves for adjustment. A balance weight may be attached to the face-plate or cast with or secured to the cap B. The lining N, 0, of metal such as white metal, is retained in dovetailed grooves in the housing and is cast with the aid of a core P, Fig. 3, the lugs U of which are inserted between the sections of the housing. The sides R of the core are flush with the sides of the housing so that when laid on a flat surface no molten metal will escape. After removal of the core, packing strips are inserted between the sections of the housing and the lining is bored to the diameter of the bearing liners to be machined. When boring main bearing liners, the bottom brass is held in the section A so that the thickness of this half will not be affected when trueing the hole, but with connecting-rod bearings trueing up is divided evenly between both brasses by adjusting the section A on the bracket D.
