Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
A microscope objective mount comprising: a mount body with thread means for screwing said mount onto a microscope, said mount body having an annular groove therearound; a tubular sleeve surrounding said mount body and covering substantially the entire length of said mount body when said mount body is screwed onto a microscope, said sleeve having a hole therethrough; and detent means engaging said groove on said mount body and said hole through said sleeve for releasably and rotatably securing said sleeve on said mount body, said detent means being releasable only with the aid of an opening tool through said hole; whereby said sleeve is freely rotatable around said mount body and cannot be removed from said mount body without an opening tool, and said mount cannot be unscrewed from said microscope with said sleeve thereon.
Claim 2
Dependent Claim
