BELL YOKE BEARING REAMERS BY F. W. BENTLEY, Jr. There is nothing in connection with the |)erformance of thebell ringer that has more influence on its action than the conditionof the yoke bearings of the bell. The necessity in most shopsof removing the bell stand and reaming it on a drilling machinefor correct alinement makes this a piece of repair work thatis very often slighted, with resultant inconvenience to theenginemen. The accompanying drawings illustrate a simply constructed setof reamers which make this a comparatively short piece of reamer in Fig. 1 is for truing up the holes to Ij in.; the s. llThJi. a, Reamers for Truing Bell Yoke Bearings reamer in Fig. 2 is for reaming the holes when worn over V/2in. In either case a bushing is then applied to the wings of thestand to take the standard 1J4 in- yoke pin. Both reamers canbe used in connection with an air motor and the operation isshown in Fig. 3. Owing to the double nature of the reamingcutters it is quite easy to keep the holes in line. The reamerseliminate all necessity of removing the stand and on one or twojobs of this kind will efifect enough saving to pay for method of truing bell yoke bearings has been developedby W. H.
