Abstract: A tool sharpening or finishing machine is provided having an improved, low cost, laterally shiftable and tiltable tool-supporting table adjacent a rotatable, abrasive wheel. The table is supported for back-and-forth shifting by a roller bearing assembly having a plurality of spaced apart and resiliently biased together bearings connected to a base, with a shiftable element received between the bearings and connected to the table. The base is preferably slotted between the spaced bearings to form a structural spring within the base, and one of the bearings is eccentrically mounted for selective variation of the effective distance between the bearings, so that the bearing assembly can be properly preloaded without the need for precision manufacture of the assembly components.

Abstract: An improved sharpening machine is provided for easy, extremely accurate sharpening of a variety of tools such as lathe, boring and cutting tools. The machine includes a rotatable, low speed, diamond or other abrasive surfaced wheel, and a tool-supporting table mounted for translatory movement along a path parallel to the wheel abrasive face. The table is further mounted for measured tilting thereof relative to the wheel face, and for shifting of the table and associated structure completely clear of the wheel to facilitate certain sharpening operations and wheel replacement. With the table pivoted completely away from the wheel, the cutting wheel can be operated in a plane perpendicular to its original operating plane. A pivotal tool guide is removably secured to the table for selective alteration of the angular position of a tool being sharpened.

Abstract: The squeeze of two opposed paper-receiving rolls of an offset printing press may be infinitely adjusted within a relatively small range by virtue of the fact that each end plate supporting the rolls has a slit therein between the axes of rotation of the rolls which will permit slight deformation of the plate in a direction transversely of the slit upon manipulation of an adjusting mechanism to shift the rolls toward and away from each other. Adjustment mechanism is provided on each plate and includes a cam that, when rotated by the longitudinal displacement of an operating link, has the effect of opening or closing a corresponding slit to thereby effect minute adjustment of the spatial relationship of the roll axes. The operating link has a specially threaded section from which the longitudinal displacement of the link is derived, the arrangement being such that the ratio of link rotation to link displacement is relatively high so that very fine adjustment of the critical roll relationship can be achieved.
