Abstract
Abstract The mount comprises a first portion adapted for receiving a yoke, a second portion adapted for connection to a cathode-ray tube, a plurality of adjustable springs interconnecting the first and second portions and means for locking the first and second portions together. The adjustable springs permit movement of the yoke along one axis while securing its position along an orthogonal axis. In one preferred embodiment, a platform is provided with projections extending therefrom. A housing on which a yoke may be mounted, is attached to the projections. The housing includes a plurality of bow springs located between the points of attachment to the projections and the yoke attachment area. Means also are included to secure the bow springs in their adjusted positions.
