Abstract: 801,049. Drawing; separating mandrels from work. TREFILERIES ET LAMINOIRS DE PRECISION GILBY-FODOR. April 24, 1957 [April 25, 1956; Aug. 10, 1956; March 12, 1957 ; March 18, 1957], No. 13035/57. Class 83 (4). In a method of extracting mandrels from long tubes drawn over them, fluid pressure is introduced between the tube wall and the mandrel surface to produce elastic expansion of the tube. In examples, a tube 1, Fig. 1, to be extracted from a mandrel 2 has the tag end 5 sealed by a hollow head 8 enclosing a selftightening seal 9. Hydraulic pressure is supplied to the head 8 through an orifice 11 and fluid reaches the drawn portion of the tube through a passage 6 in the end of the mandrel. In another example the tag end 5, Fig. 2, is sealed by a plug 16 and fluid pressure is supplied through a passage 12 in the mandrel 1. In another example a ball 23, Fig. 6, of hard polished steel or of elastic material is placed on the end of the mandrel 1 and takes the thrust of the mandrel against a spherical seat 33 of the tag end 22 during drawing. For extraction of the tube, fluid pressure is supplied through a mandrel passage 12 to transverse slots 35 in the mandrel end and the ball 23 acts as a seal so that pressure can build up in the space 37 to extract the tube. In another example, a partly spherical plug 41, Fig. 8, seals the tube end 33 and has a split cylindrical extension 45 which loosely fits in a cavity 44 on the end of the mandrel 2. The plug has an extension 40 for engagement by drawing dogs 52 during the drawing operation and fluid under pressure is supplied for the extraction process through a passage 48. A fluid seal 54 is provided in the head 49 carrying the drawing dogs 52 so that the fluid pressure may be supplied through a connection 57 on the head 49.

Abstract: 592,771. Knurling annular bodies. GENERAL MOTORS CORPORATION. May 30, 1945, No. 13518. Convention date, June 6, 1944. [Classes 83 (ii) and 83 (iv)] Making bearings.-A method of knurling a cylindrical surface comprises rotating the part to be knurled and a knurling-tool relative to each other, forcing the knurling-tool into the part to be knurled until the tool bites into the surface, said knurling-tool including a number of knurls having an angular lead relative to the axis of the part to be knurled and then permitting the tool to feed itself throughout the remainder of the part. A tool for knurling internal surfaces comprises an arbor 22 supporting three knurling rolls 26 arranged at angles of 120‹. Each roll includes stub shaft portions 28 at each end journalled in bearing-sleeves 31 in the arbor and in a cap 32 secured to the arbor by screws 38. The shafts 28 have end clearance within the bearing-sleeves to permit the roll to move axially to make up for slight discrepancies between the pitch of the knurls and the pitch of the screw feed between tool and work. To assist in feeding the knurling-tool through the annular work, a slight angular lead is provided on each roll. In Fig. 2 this is shown as 19 minutes. This angle may vary for knurls of different pitch and may be a multiple of the number of rolls used, being for example 57 minutes instead of 19 minutes when three rolls are employed. For knurling the outer surface of a cylindrical body, the knurling-rolls are carried in an annular arbor. In either case either the tool or the work may be traversed. The knurling produced by the method is stated to be of greater accuracy and particularly useful for the knurling of the supporting surface of a bearing, a copper surface being knurled and then filled with bearing metal.
