Abstract
Abstract A machine having relatively movable parts with antifriction bearing assemblies located between the moving parts. The antifriction bearing assemblies are adjustably mounted by double wedge means whereby the proper amount of preload on the bearing assemblies can be readily obtained. In addition to the double wedge adjustment, the bearing assemblies can also be mounted so as to rock or tilt, within limits, to then thereby adapt themselves between the relatively moving parts to accommodate any misalignment and to facilitate assembly of the relatively movable parts.

Claim 2
Dependent Claim
185 words
A machine comprising, two relatively moving parts, an antifriction bearing assembly between said parts and having rollers engageable witH one part for rolling thereon, adjustable means for rigidly mounting said assembly to the other part, said adjustable means comprising, a pair of wedges which are in engagement with and slideable relative to one another, one wedge being rigidly secured to said other part, the other wedge being rigidly secured to said bearing assembly, adjusting means between said other part and said other wedge, whereby said other wedge and its bearing assembly can be adjusted relative to said one wedge, said adjusting means comprising a set screw mounted in said other part and threadably engaged in one end of said other wedge, said set screw having a head adapted to receive a torque wrench, said head being exposed at the outside of said machine for engagement by said wrench, and means including a fixed pin at one end of said one wedge and an adjusting screw at the other end of said one wedge for detachably and rigidly securing said one wedge to said other part.
Claim 3
Dependent Claim
180 words
A metal working machine comprising, a stationary part and a movable part for movement adjacent and relative to said stationary part, an antifriction bearing assembly located between said parts and mounted on said movable part and having rollers engageable with said stationary part for rolling thereon, a pair of wedges each having an inclined surface which are in engagement with and slideable relative to one another, one wedge being rigidly but detachably secured to said movable part, the other wedge having means for being rigidly but detachably secured to said bearing assembly, and adjusting means between said movable part and said other wedge and comprising a set screw mounted in said other part and threadably engaged in one end of said other wedge, said set screw having a head adapted to receive a torque wrench, said head being exposed at the outside of said machine for engagement by said wrench, whereby the said other wedge and its bearing assembly can be adjusted relative to said one wedge, whereby the loading on said bearing assembly between said parts can be varied.
Claim 4
Dependent Claim
180 words
A metal working machine comprising, a stationary part and a movable part for movement adjacent and relative to said stationary part, an antifriction bearing assembly located between said parts and mounted on said movable part and having rollers engageable with said stationary part for rolling thereon, a pair of wedges each having an inclined surface which are in engagement with and slideable relative to one another, one wedge being rigidly but detachably secured to said movable part, the other wedge having means for being rigidly but detachably secured to said bearing assembly, and adjusting means between said movable part and said other wedge and comprising a set screw mounted in said other part and threadably engaged in one end of said other wedge, said set screw having a head adapted to receive a torque wrench, said head being exposed at the outside of said machine for engagement by said wrench, whereby the said other wedge and its bearing assembly can be adjusted relative to said one wedge, whereby the loading on said bearing assembly between said parts can be varied.
Claim 5
Dependent Claim
156 words
A machine comprising, two relatively moving parts, an antifriction bearing assembly between said parts and having rollers along one side which are engageable with one part for rolling thereon, said assembly having an arcuate piece secured to its other side, adjustable means for rigidly mounting said assembly to the other part, said adjustable means comprising, a pair of wedges in engagement with and slideable relative to one another and for tiltably mounting said assembly to said other part, one wedge being rigidly but detachably secured to said other part, the other wedge having an arcuate recess therein which is complementary to and receives said arcuate piece for tiltably supporting said bearing assembly relative to said other part, and adjusting means between said other part and said other wedge whereby the latter and its bearing assembly can be adjusted relative to said one wedge to vary the loading on said bearing assembly between said relatively movable parts.
Claim 6
Dependent Claim
156 words
A machine comprising, two relatively moving parts, an antifriction bearing assembly between said parts and having rollers along one side which are engageable with one part for rolling thereon, said assembly having an arcuate piece secured to its other side, adjustable means for rigidly mounting said assembly to the other part, said adjustable means comprising, a pair of wedges in engagement with and slideable relative to one another and for tiltably mounting said assembly to said other part, one wedge being rigidly but detachably secured to said other part, the other wedge having an arcuate recess therein which is complementary to and receives said arcuate piece for tiltably supporting said bearing assembly relative to said other part, and adjusting means between said other part and said other wedge whereby the latter and its bearing assembly can be adjusted relative to said one wedge to vary the loading on said bearing assembly between said relatively movable parts.
Claim 7
Dependent Claim
