Another plan is to make the bearing in parts, as in [Fig. 2479], in which the top and bottom parts of the bearing extend to the joint face on one side, but admit a chock or gib, a in the figure, which may be adjusted by a set-screw as shown. By this means the bearing area may extend all around the bore. In some cases two of such chocks and set-screws, one on each side of the journal, are employed.
Fig. 2480.
In place of the set-screws, whose ends, from receiving the pressure of the thrust, are apt to imbed themselves into the chock and to thus loosen the adjustment, wedges lifted by bolts passing up through the cap, as shown in [Fig. 2480], are employed, being preferable to the screws.
