205,896. Shorthouse, B. July 27, 1922. Ball bearings.-In a ball bearing for drawing. rollers of spinning frames &c., comprising one or more ball-races formed in a spindle or tube and two ball-retaining rings 9 each forming an outer race contained in a sleeve 8, the rings 9 are forcefitted one into each end of the sleeve 8 to confine one or more rows of balls between them and form a unit which cannot easily be dismantled. Additional means for securing the rings 9 may be provided. Each ring 9 is provided with a flange 10 which extends outside the balls to near the spindle or tube and serves to prevent distortion of the ring and to constitute a dust-excluding and oil-retaining device. In the form shown in Fig. 1, the spindle 5 is provided with two grooves 6 forming inner races for two rows of balls, and the bearing surface 15 of each ring 9 is cylindrical, the flanges 10 serving to position the bearing axially. Lubricant is supplied to the space 11 between the balls, as shown in Fig. 2, the surfaces 15 of the outer races are conical and the flanges do not touch the balls. The tangents at the points of contact with the inner and outer races are parallel. In Fig. 5, the tangents at the points of contact with the inner and outer races meet on the axis of the bearing, and a loose thrust ring 23 is located between the two rows of balls. According to the Provisional Specification, the tangents may meet at a point other than on the axis of the bearing, and the ring 23 may also serve as a cage for spacing the balls, being provided with projections engaging between the balls. Fig. 7 shows a bearing in which a single row of balls is confined between the two rings 9. For use with a wooden drawing roller, the periphery of the sleeve 8 is made polygonal and the roller is forced thereon. In the case of an iron roller, the sleeve 8 has a cylindrical periphery and is secured in the roller by a screw engaging a groove in the sleeve. Fig. 11 shows a cotton roller 32 in which the ends are bored to take the forced-in rings 9. According to the Provisional Specification, the bearing may be so constructed that it is self-aligning.
