Abstract

280,497. Bound Brook Oil-less Bearing Co., (Assignees of Claus, C.). Nov. 11, 1926, [Convention date]. Bearings. - Bearing bushes of porous compressible compositions, e.g. as disclosed in Specification 281,375, [Class 87 (ii), Moulding plastic &c. substances], are brought to final size in an apparatus comprising a shouldered mandrel 15, a co-operating die 12 and an ejector 19. The external sizing is effected by a sleeve 16 on a reduced portion of the mandrel, which, on the descent of the mandrel and under the influence of a strong spring 36 forces the bush into the die 12 against the resistance of a weaker spring 21. The continued descent of the mandrel causes the reduced part 17 thereof to size the interior of the bush the latter finally being compressed endwise to the correct length when the ejector contacts with the abutment 23. The ejector may be mechanically connected with the mandrel. The bush, which may be of compressed granulated materials e.g. copper, tin, zinc, lead and graphite may be initially impregnated with lubricating oil. The apparatus may be used to size only the internal diameter, or the external diameter, or the length of the bush. The mandrel is actuated by any external means. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the invention to the sizing of metal bearings or bushes generally. This subject-matter does not appear in the Specification as accepted.
