Hunt, of New York, has recently patentedthe ingenious device shown iu the engravings for settingup the bearings of journals, such ascrankpins and otherjournals where a stub end or strap-end is ordinarilv pro-vided. Fig. 1 is a longitudinal and fig. 2 a tranverse section of thisarrangement, which is described as follows in the specifica-tion : The crank pin or shaft at .1 is provided with the brasses. iIICNTS JOUKNAL BEARING. or boxes II . and these arc held in any suitable support, suchas the end of the COnnecling-rod D, and adjacent lo one of theboxes there is a cavity /•. into which are inserted balls orspheres /•, preferably of hard steel. A series of balls are usedof various diameters introduced into the cavity adjoining thebox or brass that is to be sel up, and a screw 0 is provided,sometimes having a tapering point, that passes into the holethrough which the balls may be introduced, ami such screwpressing upon the bills causes them to come into intimate asso-ciation and bearing one upon the other and also upon the boxthat is to be set up, and these balls slide one upon the otheras pressed upon by the scree . exert the necessary force against the whole of the outer surface of the box orbearing, to press the same to its position. By making use ofballs or sphere^ of different sizes I am enabled to obtain a sub-stantially fluid condit
