The method of forming a bearing comprises press-fitting into an inner bearing member 6, 6<SP>1</SP> having an axial bore 9, 9<SP>1</SP> an expansion pin 8, 8<SP>1</SP> to temporarily expand said inner member, placing said expanded inner member within a tubular outer race member 5, 5<SP>1</SP> applying forming pressure to said outer race member, to permanently deform it about said inner member and to produce an assembly wherein said inner member is tightly held by said formed outer race member and then withdrawing said expansion pin from said inner bearing member. The inner surface of the outer race member is rough machined or sand blasted to facilitate the bonding thereto of a low friction woven fabric material 7, and the inner bearing member is buffed or polished or chrome-plated and polished. The outer race member 5 is formed about the inner member 6 by forcing it through an extrusion die 10, Fig. 1. Dies 10<SP>1</SP>, Fig. 2, are used for forming the outer race member of the spherical type bearing. In making the spherical type bearing without the low friction lining after removing the expansion pin the assembly is subjected to a second press-forming operation in the dies 10<SP>1</SP> to bring the end portions 12 of the outer race member 5<SP>1</SP> into closer relationship with the inner member 6<SP>1</SP>. The outer race is machined prior to the second press-forming operation to reduce its thickness and eliminate the curvature of its outer surface caused by the forming dies.

Abstract: 645,617. Cleaning pipes. McGAFFEY, E. W. Aug. 5, 1947, No. 21200. Convention date, June 23, 1939. [Class 99(ii)] A device for cleaning the perforations 11 of an oil well pipe 10 comprises plungers 43, 44, 45 forming confined chambers P, S of constant volume disposed below a pump comprising a piston 23 working in a cylinder 16 operatively connected, as by a tube 29, with the chambers whereby movement of fluid between the chambers and pump is effected during movement of the plungers with respect to the pipe. The cylinder may be fixed relatively to the pipe in any selected position by an anchoring mechanism A, and the piston may move in unison with the plungers. During the downstroke of the piston operated by tubing 12, fluid in chamber S passes through valve 48 tubes 32 and 28 to the upper portion of the cylinder and at the same time fluid from the lower half of the cylinder passes through port 33, tube 29 and ports 47 into chamber P in which a pressure is created. The upstroke of the piston causes fluid from the upper half of the cylinder to pass down tubes 28, 32 and through valve 30 driving with it debris-laden fluid collected in tube 29; simultaneously, fluid from pipe 10 flows through port 13<SP>1</SP> or valve 15 into tube 14, past valve 21, into tube 22 and through port 27 into the lower half of the cylinder. The action on any series of perforations passed by the plunger 44 is a sudden reversal of fluid flow. Chemical washing fluids may be introduced into tubing 12. In modifications, only pressure or suction is created at the perforations.
