Claim 1
Independent Claim 230 words
Mounting and alignment mechanism for a microscope stage comprising: a microscope base; a movable stage carrying slide mounted upon said microscope base; an elongated mounting plate; a first pair of spaced inclined and coplanar abutment surfaces formed along one side of said plate near the ends thereof, the outer exposed edges of said surfaces being colinear with each other and being alignable parallel with the optical axis of the objective of the microscope, adjustable means for fixing said plate on said slide in parallel alignment with said axis; a stage support bracket whereon a wall is formed extending contiguously parallel to and substantially coextensive with said plate; a second pair of spaced and coplanar abutment surfaces which are formed in said bracket complementary to the first said abutment surfaces and which are inclined to lie against said first pair of abutment surfaces when the bracket is assembled on the plate, the second pair of abutment surfaces having corresponding side edges which are colinear and which are alignable parallel with an optical axis which extends through an optical condenser carried by said bracket; and interlocking holding surfaces formed in cooperatively laterally spaced position from the first and second pair of abutment surfaces on the plate and bracket, at least one of the holding surfaces being positioned at a vertically converging wedging angle to said first and second pair of abutment surfaces.
Claim 2
Dependent Claim 230 words
Mounting and alignment mechanism for a microscope stage comprising: a microscope base; a movable stage carrying slide mounted upon said microscope base; an elongated mounting plate; a first pair of spaced inclined and coplanar abutment surfaces formed along one side of said plate near the ends thereof, the outer exposed edges of said surfaces being colinear with each other and being alignable parallel with the optical axis of the objective of the microscope, adjustable means for fixing said plate on said slide in parallel alignment with said axis; a stage support bracket whereon a wall is formed extending contiguously parallel to and substantially coextensive with said plate; a second pair of spaced and coplanar abutment surfaces which are formed in said bracket complementary to the first said abutment surfaces and which are inclined to lie against said first pair of abutment surfaces when the bracket is assembled on the plate, the second pair of abutment surfaces having corresponding side edges which are colinear and which are alignable parallel with an optical axis which extends through an optical condenser carried by said bracket; and interlocking holding surfaces formed in cooperatively laterally spaced position from the first and second pair of abutment surfaces on the plate and bracket, at least one of the holding surfaces being positioned at a vertically converging wedging angle to said first and second pair of abutment surfaces.
Claim 3
Dependent Claim 44 words
A mounting and alignment mechanism for a microscope stage as set forth in claim 1 further characterized by the other of said holding surfaces being conically formed on a member which is fixed on the stage bracket in operative engagement with the wedging surface.
Claim 4
Dependent Claim 87 words
A mounting and alignment mechanism for a microscope stage as set forth in claim 2 further characterized by: the conically formed member having a flat lateral clamping surface on which it rests; a smooth cylindrical surface defining a bore extending through said member parallel to the axis of the conically formed surface and eccentrically offset therefrom; and a clamping bolt slidably fitted into said bore and threaded into said bracket to provide a clamping fit between the inclined clamping surfaces and the opposite conically surfaced clamping member.
Claim 5
Dependent Claim 134 words
A mounting and alignment mechanism for a microscope stage as set forth in claim 2 further characterized by: the conically formed member having a flat lateral clamping surface which intersects the smaller diameter of the conical surface and whereon the member rests; a bore and a contiguous shouldered counterbore extending through the conical member and being eccentric to said conical surface; a counterbored sleeve member slidably fitted within said bore and counterbore, said sleeve member having an inner cylindrical surface formed eccentrically therethrough defining an inner bore; means for rotating said sleeve member in the counterbore; and a clamping bolt fitted to said inner surface and having a head which is seated in the counterbore of said member and threaded into said bracket to clamp the conical member in a proper lateral operating position.
Claim 6
