Abstract
Abstract A supplementary microscope stage for attachment to a microscope table on which a specimen plate for a plurality of annularlyarranged and spaced specimens or samples for microscopic examination is rotatably mounted. The supplementary stage has at least one upstanding pivot pin on which the specimen plate is rotatably disposed. The pivot pin is adjustable to various positions from a normal position to bring various parts of the respective specimens or samples into view by the lens of the microscope.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
224 words
A stage for microscopes including viewing lens means and a table, comprising a stage plate mounted on said table and having a. at least one generally elongated recess b. a top wall for said recess, said wall having an elongated opening therethrough; a pivot pin in said recess and extending upwardly through said opening and upwardly of the top surface of said stage plate and adapted to receive a specimen plate with specimen areas thereon, said pivot pin engaging a pivot hole in said specimen plate, said opening in said top wall being of sufficiently greater size than said pin to permit said pin being moved about in said opening upon the application of lateral pressure to the specimen plate for aligning specimen areas with said viewing lens means; and resilient leaf spring means in said recess, said resilient means being mounted on and connected to said pin and extending longitudinally of said recess and having portions thereof frictionally engaged with and slidable on the top wall of said recess, said pin being held in position by said resilient means and freely movable by said specimen plate in at least opposite directions in said opening from a central position when said specimen plate is laterally moved relative to said stage plate, said spring means retaining said pin and specimen plate in any adjusted position.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
The invention defined by claim 1, wherein said stage plate has a light transmitting opening therein intermediate its ends and spaced from the opening in the top wall of the recess.
