Microscope

Claim 2

A microscope comprising: a base having means defining a top and bottom opening, a support member including a generally vertical neck extending from said base adjacent to top opening therein and a generally horizontal arm projecting over the top opening in the base and having a hole therethrough, a lens assembly fitted within the hole in the horizontal arm and including a lens, lens holder and eyepiece, a disc-shaped holder fitted within and covering the top opening in the base, said disc-shaped holder having means extending downwardly from a bottom surface thereof for holding said battery, a mirror, means for rotating said mirror into different planes, said disc-shaped holder having means extending upwardly from a top surface thereof for supporting said mirror and said means for rotating said mirror, a light bulb, conductor wires coupling between said battery and light bulb, said support member including means defining an aperture through which said bulb extends, a plate covering the bottom opening in the base, a switch means coupled between said battery and bulb for controlling illumination of said bulb. and means for downwardly biasing said switch means with at least a portion thereof extending below said plate, said portion of said switch means disposed near an outer edge of said base, wherein said microscope has a weight that is insufficient to cause said switch means to close.

Claim 3

The microscope of claim 1 wherein said switch means is positioned below said battery at an end thereof and includes a conductive tab means adapted to eLectrically contact one terminal of the battery when said switch means is closed.

Claim 4

The microscope of claim 2 wherein said switch means comprises means for pivotally securing said tab means at one end to a top surface of said plate, said portion of said switch means including a pushbutton passing through an opening in the plate and touching said tab means at its other end.

Claim 5

The microscope of claim 2 wherein said switch means comprises means for pivotally securing said tab means at one end to a top surface of said plate, said portion of said switch means including a pushbutton passing through an opening in the plate and touching said tab means at its other end.

Claim 6

A microscope comprising; a base having means defining a top and a bottom opening, a support member including a generally vertical neck extending from said base adjacent the top opening therein and a generally horizontal extension projecting over the top opening in the base and having a hole therethrough, a lens carrier including a generally vertical base mating with a top opening in the neck of said support member, and an arm extending over the horizontal extension and having a hole in alignment with the hole in the horizontal extension, said horizontal extension having a flat upper surface for receiving a slide and means for maintaining the slide in position, means coupled from said base for forceably holding said vertical base of said lens carrier in the top opening in the neck, means for adjusting said lens carrier relative to said support member, a lens assembly fitted within the hole in the horizontal arm and including a lens, lens holder and eyepiece, a disc-shaped holder fitted within and covering the top opening in the base, a battery, means for securing said battery below said holder and in said base, a light bulb, means for supporting said light bulb with a portion disposed in said support member and an illuminating portion extending through an aperture in a slanted wall defining a part of said support member, conductor wires coupling between said battery and light bulb, a mirror assembly, means for supporting said mirror assembly above said disc-shaped holder, a plate covering the bottom opening in the base, a switch coupled between said battery and bulb for controlling illumination of said bulb and including a pushbutton, and means resiliently supporting said pushbutton below said plate, said plate having a hole for receiving said pushbutton, said microscope having a weight insufficient to cause said switch to close without application of additional downward force.

Claim 7

A microscope comprising; a base having means defining a top and a bottom opening, a support member including a generally vertical neck extending from said base adjacent the top opening therein and a generally horizontal extension projecting over the top opening in the base and having a hole therethrough, a lens carrier including a generally vertical base mating with a top opening in the neck of said support member, and an arm extending over the horizontal extension and having a hole in alignment with the hole in the horizontal extension, said horizontal extension having a flat upper surface for receiving a slide and means for maintaining the slide in position, means coupled from said base for forceably holding said vertical base of said lens carrier in the top opening in the neck, means for adjusting said lens carrier relative to said support member, a lens assembly fitted within the hole in the horizontal arm and including a lens, lens holder and eyepiece, a disc-shaped holder fitted within and covering the top opening in the base, a battery, means for securing said battery below said holder and in said base, a light bulb, means for supporting said light bulb with a portion disposed in said support member and an illuminating portion extending through an aperture in a slanted wall defining a part of said support member, conductor wires coupling between said battery and light bulb, a mirror assembly, means for supporting said mirror assembly above said disc-shaped holder, a plate covering the bottom opening in the base, a switch coupled between said battery and bulb for controlling illumination of said bulb and including a pushbutton, and means resiliently supporting said pushbutton below said plate, said plate having a hole for receiving said pushbutton, said microscope having a weight insufficient to cause said switch to close without application of additional downward force.

Claim 8

The microscope of claim 5 wherein said disc-shaped holder includes means for supporting said battery therebelow and said mirror assembly thereabove.
