Abstract
Abstract An improved mount for an optical lens or similar device for achieving X-Y adjustment which includes four diametrically opposed 90° spaced knife edges on a lens ring opposed on one side by a spring and on the other side by a micrometer adjustment to provide positive control in the X and Y directions, each motion being independent of the other.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
167 words
A mounting structure for an optical element and the like for achieving X-Y adjustment on a Z axis which comprises: a. a support ring having four tangential slide surfaces spaced 90° from each other around the circumference to form orthogonal pairs, b. four slide blocks engaging, respectively, a slide surface on side ring, over a tangential lineal span, in a tongue and groove sliding relationship on the tangent of said surface, c. a support frame surrounding said support ring, d. four brackets on said frame spaced 90° from each other around said frame to register with said surfaces on said ring, e. a radially disposed shaft on each said bracket to support each said slide blocks, respectively, f. means on two of said adjacent brackets resiliently biasing said shafts and two of said slide blocks radially inwardly against respective slide surfaces, and g. manually operable means radially advanceable and retractable on said remaining brackets to control the radial position of said remaining two shafts and slide blocks.
