Abstract
Abstract Elastic bearings supporting bearing bushings for shafts are mounted in recesses in plates of a machine frame. The elastic material is shaped so that, in at least one predetermined direction transverse to the longitudinal axis of the shaft, its dimension is a multiple of that in other directions. What is achieved thereby is that the shaft is constrained to move in one defined direction only.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
101 words
Apparatus for mounting the trunions of a printing machine platen to constrain oscillations resulting from type character impacts thereagainst essentially to a predetermined direction only comprising, machine side frames having generaly non-circular openings having their longest dimension extending in said predetermined direction, complimentary shaped elastic noise buffers mounted in said frame openings, and trunion bushings mounted in openings through and adjacent one end of said buffers so that the dimension of the buffers relative to the trunion axis in said predetermined direction is a multiple of the dimensions in other directions such that oscillations are constrained essentially to said predetermined direction.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
29 words
Apparatus as recited in claim 1, said side frame openings and noise buffers having oval shapes with the long dimension extending horizontally and transverse the axis of said trunions.
Claim 4
Dependent Claim
26 words
Apparatus as recited in claim 1, said buffers having inner and outer flanges surrounding the inner and outer sides of said side frames defining said openings.
