Abstract
Abstract An arrangement for detachably mounting an examining member onto a microscope comprises a horizontally extending dovetail key on the examining member, and a horizontally extending dovetail groove formed in the body of the microscope. The dovetail connection permits the examining member to be mounted in place through its horizontal movement, thereby facilitating its mounting and removal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
213 words
Detachable mounting apparatus for use with a microscope having support means movable in a first plane towards and away from optical objective means, comprising: a support member extended from said support means in a second plane substantially perpendicular to said first plane, said support member having a first dovetail joint portion formed on each of a pair of opposed surfaces extended in said second plane; means for supporting a specimen to be examined; a first examination accessory member; each of said specimen support means and said first examination accessory member having a cooperating dovetail joint portion extended in said second plane and adapted to detachably closely mate with one of said first dovetail joint portions to independently rigidly position each of said specimen support means and said first examination accessory member to one of said pair of opposite support member surfaces and within the viewing cone of said optical objective means, whereby each of said specimen support means and said first examination accessory member is independently removable from said support member by sliding disengagement of said first and cooperating dovetail joint portions in said second plane without disturbing the position relative to said microscope and said movable support means of the other one of said specimen support means and first examination accessory member.

Detachable mounting apparatus for use with a microscope having support means movable in a first plane towards and away from optical objective means, comprising: a support member extended from said support means in a second plane substantially perpendicular to said first plane, said support member having a first dovetail joint portion formed on each of a pair of opposed surfaces extended in said second plane; means for supporting a specimen to be examined; a first examination accessory member; each of said specimen support means and said first examination accessory member having a cooperating dovetail joint portion extended in said second plane and adapted to detachably closely mate with one of said first dovetail joint portions to independently rigidly position each of said specimen support means and said first examination accessory member to one of said pair of opposite support member surfaces and within the viewing cone of said optical objective means, whereby each of said specimen support means and said first examination accessory member is independently removable from said support member by sliding disengagement of said first and cooperating dovetail joint portions in said second plane without disturbing the position relative to said microscope and said movable support means of the other one of said specimen support means and first examination accessory member.
Claim 3
Dependent Claim
49 words
An arrangement according to claim 1, in which said specimen support means and said first examination accessory member each include an attachment member extended therefrom in said second plane, each attachment member having one of said cooperating dovetail joint portions formed in said first plane on a surface thereof.
Claim 4
Dependent Claim
58 words
An arrangement according to claim 2, in which each of said first pair of dovetail joint portions is a dovetail key extended in said first plane outwardly from one of said support member opposed surfaces; and each said attachment member cooperating dovetail joint portion is a cooperating dovetail groove formed into a first surface of said attachment member.
Claim 5
Dependent Claim
79 words
An arrangement according to claim 1 in which said first examination accessory member further includes a second dovetail joint portion extended in said second plane in another surface opposite said cooperating dovetail joint portion; and a second examination accessory member having another attachment member extended in said second plane, said another attachment member having another cooperating dovetail joint portion adapted to detachably closely mate with said second dovetail joint portion to rigidly position said second examination accessory member thereto.
Claim 6
Dependent Claim
16 words
