Abstract
Abstract A remote control motor driven lamp with motors to drive the lamp assembly in two perpendicular planes and a motor to change the distance between the lamp filament and the reflector in such a manner as to vary the beam characteristics. The lamp is capable of being operated from at least one remote station enabling the operator to alter both the beam characteristics and the beam direction from the remote station.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
146 words
A remote controlled motor driven lamp assembly for the projection of a searchlight beam comprising: lamp housing means, reflector means attached to said lamp housing means, lamp filament means disposed in a spatially predetermined relation to said reflector means, yoke means rotatably attached to said lamp housing means and disposed in supporting relation thereto, at least one drive motor means, first arm means rigidly affixed at one end to said yoke means, and said drive motor means disposed in driving engagement with the other end of said first arm means, second arm means rigidly affixed at one end to said lamp housing means and said drive motor means disposed in driving engagement with the other end of said second arm means, whereby activation of said motor means rotates said lamp housing means relative to said yoke means so as to provide motion of the searchlight beam.
Claim 2
Dependent Claim
146 words
A remote controlled motor driven lamp assembly for the projection of a searchlight beam comprising: lamp housing means, reflector means attached to said lamp housing means, lamp filament means disposed in a spatially predetermined relation to said reflector means, yoke means rotatably attached to said lamp housing means and disposed in supporting relation thereto, at least one drive motor means, first arm means rigidly affixed at one end to said yoke means, and said drive motor means disposed in driving engagement with the other end of said first arm means, second arm means rigidly affixed at one end to said lamp housing means and said drive motor means disposed in driving engagement with the other end of said second arm means, whereby activation of said motor means rotates said lamp housing means relative to said yoke means so as to provide motion of the searchlight beam.
Claim 3
Dependent Claim
65 words
A lamp assembly as in claim 1 wherein said lamp housing means further comprises an outer sleeve portion integrally formed thereon and rigidly affixed to said second arm means, said yoke means further comprising a cylinder portion integrally formed thereon and rigidly affixed to said first arm means, said outer sleeve portion disposed in surrounding relationship to said cylinder portion and in rotatable engagement therewith.
Claim 4
Dependent Claim
61 words
A lamp assembly as in claim 1 wherein said drive motor means further comprises motor drive shaft means protruding therefrom and disposed in driving relation to said second arm means, said second arm means further comprising stud means having aperture means formed therein, said motor drive shaft means disposed in protruding relationship within said aperture means and in rotatable engagement therewith.
Claim 5
Dependent Claim
46 words
A lamp assembly as in claim 3 wherein said motor drive shaft means further comprises a first threaded portion integrally formed thereon, said aperture means comprises a second threaded portion formed on the interior surface thereof and disposed in rotatable engagement with said first threaded portion.
Claim 6
Dependent Claim
25 words
A lamp assembly as in claim 1 further comprising focus motor means connected in driving relation between said lamp filament means and said reflector means.
Claim 7
Dependent Claim
25 words
A lamp assembly as in claim 5 wherein said focus motor means further comprises connector means protruding therefrom and drivingly engaging said lamp filament means.
Claim 8
Dependent Claim
41 words
A lamp assembly as in claim 6 wherein said connector means includes a connector threaded portion integrally formed thereon, said lamp filament means includes a threaded aperture portion integrally formed therein and disposed for rotatable engagement with said connector threaded portion.
Claim 9
Dependent Claim
41 words
A lamp assembly as in claim 5 further comprising a plurality of remote control means electrically connected to said focus motor means whereby activation of said remote controlled means regulates the distance between said lamp filament means and said reflector means.
Claim 10
Dependent Claim
37 words
A lamp assembly as in claim 1 further comprising a plurality of remote control means electrically connected to said drive motor means whereby activation of said remote controlled means regulates the rotation of said lamp housing means.
Claim 11
Dependent Claim
31 words
A lamp assembly as in claim 9 wherein at least one of the plurality of remote control means comprises a means remotely connected to energize and de-energize said drive motor means.
Claim 12
Dependent Claim
22 words
A remote control switch as in claim 10 wherein a plurality of positions of said switch means energize said drive motor means.
Claim 13
Dependent Claim
20 words
A remote control switch as in claim 10 futher comprising means to vary the speed of said drive motor means.
Claim 14
Dependent Claim
28 words
A lamp assembly as in claim 1 further comprising first limit switch means disposed in path interrupting relation to the path of travel of said lamp filament means.
Claim 15
Dependent Claim
28 words
A lamp assembly as in claim 1 further comprising second limit switch means disposed in path interrupting relation to said path of travel of said lamp housing means.
