Title: Ply-turning apparatus for the manufacture of pneumatic tyres
IPC: B29D30/32
Filed: 1962-07-03
Abstract: Apparatus for turning radially inwards the ends of tyre ply material 33 carried on a tyre building former (Fig. 3) comprises a rigid annular support 8, enclosing an inflatable annular bag 1, the bag having axial reinforcement 7 and being secured by at least two portions 2, 3 to the support 8 and to axially movable, mounting means 15, the apparatus being located coaxially with the former 24. The bag 1 is circumferentially stretched when beads 2, 3 are fitted to members 8, 15, and reinforcement 7 prevents the bag being axially stretched. Fig. 3 shows the bag deflated by applying a vacuum, when springs 21 move means 15 away from support 8, and the apparatus is positioned around ply 33 on the former. The bag is then inflated and since portion 6 is axially inextensible, draws means 15 towards support 8 as the bag presses the ends of the ply radially inwards (Fig. 4, not shown). Finally, a ring 36 is advanced leftwards, pressing the bag and ply further. Fig. 5 (not shown) illustrates apparatus in which the spring 21 is replaced by a pneumatic cylinder. Fig. 9 shows a bag 60 adapted to press two ends of a ply 46 about a central former 44, two means 15 and rings 36 (not shown) being employed. Fig. 10 (not shown) illustrates use of that apparatus in applying a tread layer to a carcass mounted on an inflated diaphragm.

Title: Railway vehicle suspension height adjustment device
IPC: B61F5/50
Filed: 1970-01-29
Abstract: A height adjustment device for each spring 23 of a railway vehicle bogie allows adjustment of body height to compensate for wheel wear. The device comprises coaxial substantially circular elements 27, 29, a wide rim on the upper surface of the lower element 27 being divided into equiangular sectors 39 each subdivided into equiangular subsectors 41, 43, 45 of different heights, and the lower surface of the upper element 29 having the same number of equiangularly spaced depending radial ribs 49 as there are sectors 39 on the lower element, the elements being rotatable one relative to the other to seat the ribs 49 on selected sets of subsectors 41, 43 or 45 to adjust the height of the device. The ribs 49 have V- section lower faces 53 which engage V-section surfaces 51 of the subsectors 41, 43, 45. An annular rib 47 on the upper element 29 engages the cylindrical inner edge of the lower element rim to hold the elements coaxial. The upper element 29 is resiliently connected to a spring seat 25 of a helical coil spring 23 (Fig. 3) by an elastomeric pad 31. The lower element 27 has a boss 55 engaging a socket in a bogie side member 13. To adjust the height, the spring seat 25 is raised by jacks J (Figs. 7, 8, not shown) to bring the upper element 29 clear of the lower element 27, the latter then being rotated to the required position and locked by a bolt (67) (Fig. 5, not shown). The bogie comprises side frames 13 rigidly connected by transoms, the centre transom 9 carrying a bolster 15 via the springs 23. The bolster is centrally pivoted to the vehicle body underframe U. Fore-and-aft links 26 connect brackets 22 on the bolster to brackets (24) on the transom (9) (Fig. 1, not shown). Lateral and vertical shock absorbers are included between the bolster and the transom 9. In Fig. 10, air springs 23 replace the coil springs of Fig. 3, each comprising a flexible diaphragm 83 between a cylinder 21a and a plunger 81, the cylinder being filled with compressed air from a surge chamber 85 formed in the hollow interior of the bolster 15a. A rod 47a extends downwards from the element 29a for engagement by a jack J during height adjustment.

Ball races are formed on the undersurface of the flange 3 and at 5 on the bearing box for the lower group of balls, and compressed at 4 on the unflanged part of the upper end of the fork and on the bearing box at 7, for the upper group of boxes. A snap catch 10 releasably locks the fork in the bearing box 1 which has a collar 8 to receive a mounting pin or tubular leg. In modifications an upwardly directed collar or edge flanges are provided on the bearing box for insertion in a bore or in slots in a mounting plate or container bottom, or a bearing plate welded to the upper end of the fork has upper and lower semi-circular flanges formed with edge parts of arcuate cross-section to provide parts of the upper and lower face races, respectively, which are connected by diametrically opposed channels in the mounting plate for passage of the balls. In a further modification the upper end of a straight oblique fork, received in a frusto-conical bearing box, has two flanges of unequal length, the upper group of balls being above the flanges and the lower group of balls between the ends of the flanges and the channels for passage of the balls at the ends of the flanges being located at the axis about which the castor tends to tilt in use, spacing balls, smaller than the bearing balls, being inserted through a U-shape recess in the upper edge of the fork to reduce the spacing between the balls.
