Abstract

23,958. Tomperley, J., and Temperley, J. R. Dec. 1. Axle-boxes; axles, wearing-surfaces formed or fixed on; lubricating.-Relates to the bearings and the lubrication of wheels which run on fixed axles, Fig. 1 being a section through one form. The fixed axle c has a soft metal bush d secured on by a pin e, and within the hub of the wheel a a steel bush b is secured. Rotation of the wheel wears down the soft metal bush d, so that the contacting parts of the bushes d, b always have the same radius, as shown in diagrammatic section in Fig. 3. Fig. 4 shows the axle d of a wheel adapted to run in both directions, the parts f, f<1> and f<1>, f<2> being the wearing-surfaces for opposite directions. In modifications, the ridge f is avoided by means of a longitudinal groove, or the bush d may be in two halves with grooves between them. The bearing is lubricated by means of a passage k which leads from the oil chamber l<1>. The lubricant is introduced through a hole t in the plug p. Fig. 7 shows in section a modified lubricating-axle h, into which the lubricant is introduced through a hole l and from which it passes through a hole k. The screw n takes against the frame, and so prevents rotation of the axle.
