An improved land vehicle periscope having three concentric cylinders comprising an innermost cylinder have a ninety degree elbow on an upper end of said cylinder, a plate permanently affixed across said elbow by bracket means, an obliquely positioned first reflecting mirror affixed to said plate, said mirror reflecting an image vertically downward through said cylinders to a second reflecting mirror, called a viewing mirror, said innermost cylinder having a lower end, said lower end containing an integral, outwardly flared portion which is slotted in a gear like manner along the full circumference of said innermost cylinder, said flared and slotted portion resting on a top surface of an inside shoulder of a two sectioned, molded mounting base, a second cylinder, called a middle cylinder, concentric with and surrounding said innermost cylinder and having an upper portion on which a horizontal, tubular member is an integral part thereof, said horizontal tubular member retaining a vertical, plane lens at each end of said tube and a single vertically disposed convex lens between one plane lens and said first reflecting surface, the edges of said plane lenses and said convex lens being aligned parallel, said middle cylinder having a lower portion having an integral tab bent outward and positioned to prevent said middle cylinder from rotating, a rigid outermost cylinder, concentric with said innermost cylinder and said middle cylinder, and serving as the rigid outer protective cover and frame of said periscope, said outermost cylinder containing two integrally formed vertically disposed slots, one said slot cooperating with said tab of said middle cylinder to prevent rotation thereof the other said slot for channelling means to drive said innermost and said middle cylinder for elevation thereof, aid outer most cylinder having an upper portion with an inwardly flared flange as an integral part thereof, the lower portion of said cylinder secured in the top surface of the two sectioned base member on said inside shoulder common to the resting surface of said innermost cylinder, said base member also supporting mounting tabs disposed below said concentric cylinders said tabs attached directly to said viewing mirror and oriented within said base member to horizontally redirect light falling substantially vertically downward through said innermost cylinder to a viewing opening, said opening vertically supporting a concave lens, said base two sectioned member also having means for rotating said innermost cylinder consisting of a rotatable flexible coiled spring through both sections of said base driven by rod means within said coiled spring, said rod means having a gear connected thereto, the gear having an axis aligned vertically and in driving engagement with said slotted integral outwardly flared portion of said innermost cylinder, whereby said innermost cylinder and hence said first reflecting mirror rotates when said rod is rotated.

An improved land vehicle periscope having three concentric cylinders comprising an innermost cylinder have a ninety degree elbow on an upper end of said cylinder, a plate permanently affixed across said elbow by bracket means, an obliquely positioned first reflecting mirror affixed to said plate, said mirror reflecting an image vertically downward through said cylinders to a second reflecting mirror, called a viewing mirror, said innermost cylinder having a lower end, said lower end containing an integral, outwardly flared portion which is slotted in a gear like manner along the full circumference of said innermost cylinder, said flared and slotted portion resting on a top surface of an inside shoulder of a two sectioned, molded mounting base, a second cylinder, called a middle cylinder, concentric with and surrounding said innermost cylinder and having an upper portion on which a horizontal, tubular member is an integral part thereof, said horizontal tubular member retaining a vertical, plane lens at each end of said tube and a single vertically disposed convex lens between one plane lens and said first reflecting surface, the edges of said plane lenses and said convex lens being aligned parallel, said middle cylinder having a lower portion having an integral tab bent outward and positioned to prevent said middle cylinder from rotating, a rigid outermost cylinder, concentric with said innermost cylinder and said middle cylinder, and serving as the rigid outer protective cover and frame of said periscope, said outermost cylinder containing two integrally formed vertically disposed slots, one said slot cooperating with said tab of said middle cylinder to prevent rotation thereof the other said slot for channelling means to drive said innermost and said middle cylinder for elevation thereof, aid outer most cylinder having an upper portion with an inwardly flared flange as an integral part thereof, the lower portion of said cylinder secured in the top surface of the two sectioned base member on said inside shoulder common to the resting surface of said innermost cylinder, said base member also supporting mounting tabs disposed below said concentric cylinders said tabs attached directly to said viewing mirror and oriented within said base member to horizontally redirect light falling substantially vertically downward through said innermost cylinder to a viewing opening, said opening vertically supporting a concave lens, said base two sectioned member also having means for rotating said innermost cylinder consisting of a rotatable flexible coiled spring through both sections of said base driven by rod means within said coiled spring, said rod means having a gear connected thereto, the gear having an axis aligned vertically and in driving engagement with said slotted integral outwardly flared portion of said innermost cylinder, whereby said innermost cylinder and hence said first reflecting mirror rotates when said rod is rotated.
Claim 3
Dependent Claim
133 words
A land vehicle periscope as recited in claim 1, further comprising a periscope elevating, direct-current motor mounted on said base between said viewing mirror and said base, two wires connecting said motor through both sections of said base to an electric polarity reversing switch externally disposed to said periscope, said motor having a vertically disposed threaded shaft mounted for rotation by and extending upwardly from said motor, a square nut mounted on said threaded shaft and supporting said flange of said innermost cylinder, said square nut engagingly channelled in said outermost cylinder to prevent rotation of said nut when said vertically disposed, threaded shaft is rotated by said motor, whereby said innermost cylinder and said middle cylinder are raised or lowered with respect to said outermost clylinder when said direct-current motor is energized.
