Abstract

Abstract A first slide is guided in a first rectilinear path in a second slide which is guided on the stage of a microscope in a second rectilinear path at right angles to the first path, with the first slide removably receiving in located position thereon a plate with orderly grouped specimen areas any one of which is, by movement of the first slide in and with the second slide, alignable with the optical axis of the microscope. There are also provided fixed reference marks and a pointer on an extension of the first slide, of which the reference marks are so coordinated with the optical microscope axis and with the specimen areas of a located plate on the first slide that on alignment of the pointer with any particular reference mark a specimen area associated therewith is in alignment with the optical microscope axis.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 311 words
A self-contained microscope location finder for use with a rectangular plate having in its top surface a plurality of cup formations arranged in a given pattern of spaced parallel longitudinal and transverse rows, with each cup formation being at the intersection of a longitudinal and a transverse row, said finder comprising a base; a slide with an extension member; means on said base for supporting and guiding said slide for movement in a given field in Either of two transverse paths in a first plane; means on said slide for removable placement thereon of a plate in a certain located position in which the top surface thereof is parallel to said first plane, with any cup formation in a located plate on said slide being alignable with a fixed reference axis normal to said first plane by movement of said slide within said field; a member on said base outside, and on one side of, said field; reference marks on one of said members and being in number equal to that of the cup formations in a plate, with said reference marks being in a plane parallel to said first plane and arranged in spaced parallel longitudinal and transverse rows of the same pattern as the cup formations in a plate, and the longitudinal and transverse rows of reference marks being parallel to the longitudinal and transverse rows, respectively, of cup formations in a located plate on said slide; a pointer on the other of said members so coordinated with said reference marks that on alignment of said pointer with any reference mark a corresponding cup formation in a locaed plate on said slide is in alignment with said reference axis; and means of said base for mounting the latter on the stage of a microscope for adjustability thereon to bring said reference axis into coincidence with the optical microscope axis.
Claim 2
Dependent Claim 311 words
A self-contained microscope location finder for use with a rectangular plate having in its top surface a plurality of cup formations arranged in a given pattern of spaced parallel longitudinal and transverse rows, with each cup formation being at the intersection of a longitudinal and a transverse row, said finder comprising a base; a slide with an extension member; means on said base for supporting and guiding said slide for movement in a given field in Either of two transverse paths in a first plane; means on said slide for removable placement thereon of a plate in a certain located position in which the top surface thereof is parallel to said first plane, with any cup formation in a located plate on said slide being alignable with a fixed reference axis normal to said first plane by movement of said slide within said field; a member on said base outside, and on one side of, said field; reference marks on one of said members and being in number equal to that of the cup formations in a plate, with said reference marks being in a plane parallel to said first plane and arranged in spaced parallel longitudinal and transverse rows of the same pattern as the cup formations in a plate, and the longitudinal and transverse rows of reference marks being parallel to the longitudinal and transverse rows, respectively, of cup formations in a located plate on said slide; a pointer on the other of said members so coordinated with said reference marks that on alignment of said pointer with any reference mark a corresponding cup formation in a locaed plate on said slide is in alignment with said reference axis; and means of said base for mounting the latter on the stage of a microscope for adjustability thereon to bring said reference axis into coincidence with the optical microscope axis.
Claim 3
Dependent Claim 64 words
A location finder as in claim 1, in which said base has a bottom surface, and said mounting means include said bottom surface which is adapted to rest on top of the stage of a microscope, and further provide clips carried by said base underneath said bottom surface and spring-urged toward the latter for engagement with the bottom of the stage of a microscope.
Claim 4
Dependent Claim 47 words
A location finder as in claim 1, in which said mounting means provide a hollow frame formation on said base adapted to embrace the sides of a microscope stage with clearance, and set screws in said frame formation for engagement with the sides of a microscope stage.
Claim 5
Dependent Claim 152 words
A location finder as in claim 1, in which said base is a first open rectangular frame having spaced parallel side bars and spaced parallel end bars, said slide guiding means provide first longitudinal guide grooves in said end bars facing each other and lying in a plane parallel to said first plane, a second open rectangular frame having second spaced parallel end bars and second parallel side bars parallel to and spaced closer than those of said first frame and provided with second longitudinal guide grooves facing each other and lying in a plane parallel to said first plane, with said second frame being with its end bars guided for movement in said first grooves, and said slide being guided for movement in said second grooves, and one of said end bars of said first frame has an extension forming said member on said base and provided with said reference marks.
Claim 6
Dependent Claim 69 words
A location finder as in claim 4, in which said slide is a third open rectangular frame having third spaced parallel end bars and third spaced parallel side bars, with said third bars having inward ledges and forming with the latter a receptacle for removable placement therein of a plate in said certain located position, and said slide extension member is transparent and outside the confines of said receptacle.
