Abstract
Abstract A yoke is mounted on an adjustable tripod base and a motor supplies power to rotate the yoke within limits, around a vertical axis. A planar mirror is held within the yoke and a further motor extends through one arm of the yoke to rotate the mirror within limits, around a horizontal axis. Microswitches control the degree of rotation in both axes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
240 words
A mirror assembly in conjunction with a source of electrical energy and comprising in combination a base, a yoke extending upwardly from said base, first electric motor means connected to said source of electrical energy, a drive shaft for said first electric motor means, said drive shaft being operatively connected to said yoke for rotating said yoke within limits, around a first axis, a planar mirror component bearingly mounted within the arms of said yoke, and second electric motor means connected to said source of electrical energy, a drive shaft for said second electric motor means, said drive shaft being operatively connected to said mirror component for rotating same within limits, around a second axis within said yoke, at right angles to said first axis, said base including a central standard extending upwardly therefrom, said first electric motor being mounted within said standard, said yoke including a mounting shaft, a bearing in said standard above said first electric motor means, said mounting shaft being supported for rotation within said bearing and being operatively connected to the drive shaft of said first electric motor means, and means to control the degree of rotation of said yoke, said last mentioned means including a striker plate secured to said yoke, a pair of microswitches operatively connected between said first electric motor means and said source of electrical energy, and being engageable by said striker plate at the extremities of rotation of said yoke.
Claim 2
Dependent Claim
240 words
A mirror assembly in conjunction with a source of electrical energy and comprising in combination a base, a yoke extending upwardly from said base, first electric motor means connected to said source of electrical energy, a drive shaft for said first electric motor means, said drive shaft being operatively connected to said yoke for rotating said yoke within limits, around a first axis, a planar mirror component bearingly mounted within the arms of said yoke, and second electric motor means connected to said source of electrical energy, a drive shaft for said second electric motor means, said drive shaft being operatively connected to said mirror component for rotating same within limits, around a second axis within said yoke, at right angles to said first axis, said base including a central standard extending upwardly therefrom, said first electric motor being mounted within said standard, said yoke including a mounting shaft, a bearing in said standard above said first electric motor means, said mounting shaft being supported for rotation within said bearing and being operatively connected to the drive shaft of said first electric motor means, and means to control the degree of rotation of said yoke, said last mentioned means including a striker plate secured to said yoke, a pair of microswitches operatively connected between said first electric motor means and said source of electrical energy, and being engageable by said striker plate at the extremities of rotation of said yoke.
Claim 3
Dependent Claim
98 words
The assembly according to claim 1 in which said yoke includes a pair of substantially vertical spaced and parallel arms, a clamp engaging the opposite side edges of said mirror component, a shaft extending from one of said clamps, a bearing in one of said arms of said yoke engageable by said shaft, said second electric motor means being secured outboard of the other of said arms, said drive shaft of said second electric motor mEans being connected to the other of said clamps and means to limit the rotation of said mirror component around said horizontal axis.
Claim 4
Dependent Claim
75 words
The assembly according to claim 2 in which said last mentioned means includes a microswitch holder plate secured to one of said arms, a pair of microswitches on said plate and being operatively connected between said second electric motor means and the source of electrical energy, means to adjust said microswitches relative to said plate, one of said clamps engaging said microswitches at the extremities of rotation of said mirror component around said horizontal axis.
Claim 5
Dependent Claim
33 words
The assembly according to claim 1 which includes friction pad means between said mounting shaft and said central post to smooth out any irregularities of rotational movement between said yoke and said base.
Claim 6
Dependent Claim
33 words
The assembly according to claim 2 which includes friction pad means between said mounting shaft and said central standard to smooth out any irregularities of rotational movement between said yoke and said base.
Claim 7
Dependent Claim
33 words
The assembly according to claim 3 which includes friction pad means between said mounting shaft and said central standard to smooth out any irregularities of rotational movement between said yoke and said base.
