Abstract

254,334. Standard Telephones & Cables, Ltd., (Assignees of Harrison, H. C.). May 29, 1925, [Convention date]. Tool-arms and mountings. - The tool-arm or stylus-bar of a soundbox is pivoted on ball bearings, and the adjustment of the balls in their race is maintained by magnetic means. In the construction shown, the stylus-bar 3 has a permanently magnetized transverse supporting- bar 5, with tapered ends resting on balls 6. These are arranged in tapered ball-races 4 in a bracket 2 of magnetic material, mounted on the sound-box casing. The magnetic force automatically compensates for wear on the pivots.
