1,163,747. Bearings. CLIVE INVESTMENTS PTY. Ltd. 21 Sept., 1966 [15 Oct., 1965], No. 42179/66. Heading F2A. [Also in Division E1] A block 9 is mounted in a housing by mating grooves and projections. In Fig. 2 the block 9 comprises a housing 10 of U-shaped cross-section, having a half-cylindrical recess receiving a roller 11. The housing 10 is slid into channel 20 in housing 17 so that grooves 16, 22 and the projections engage and the top 23 of the block is spaced from web 21 by the desired amount and retained in position by screws 24. Two blocks are positioned in channel 20 with different spacing from web 21 to compensate for the frame not being rectangular. The grooves 16 are of V-form, or square (Fig. 3, not shown) or curved (Fig. 4, not shown). A sliding door is supported at the top in Figs. 5 and 6 (not shown), and at the bottom in Fig. 8 (not shown). The partially split block of Fig. 9 (not shown), is secured to a housing by screwing a large screw into the split. |
