Motor controlled lamp

Claim 2

An electric motor-controlled lamp characterized by its compact size, streamlined and unitary appearance and concise relationship of components comprising, in combination, a pedestal support having an .Iadd.unsupported free .Iaddend.end, an enclosed, hollow lamp housing having an opening defined therein, said pedestal end extending into the interior of said housing through said opening, a first gear connected to said pedestal at said end thereof within said housing having a first axis, a support member rotatably mounted upon said pedestal end adapted to rotate about said first axis, pivot means pivotally supporting said housing upon said support member for oscillation about a second axis perpendicularly disposed to said first axis, a second gear connected to, and within, said housing concentrically disposed about said second axis, first electric motor drive means mounted upon said support member within said housing in operative engagement with said first gear, second electric motor drive means mounted upon said support member within said housing .Iadd.adjacent said first motor drive means .Iaddend.in operative engagement with said second gear, a lamp mounted upon said housing and control means associated with said electric motor drive means.

Claim 3

In an electric motor-controlled lamp as in claim 1, a first friction clutch connecting said first gear to said pedestal, a second friction clutch connecting said second gear to said housing, each of said friction clutches including predetermined friction producing means to frictionally connect said clutches to its associated gear.

Claim 4

In an electric motor-controlled lamp as in claim 1, a first friction brake interposed between said support member and said pedestal braking rotation of said support member about said first axis, and a second friction brake interposed between said housing and said support member braking rotation of said housing about said second axis, said friction brakes dampening vibrations occurring between the relatively rotating components thereof.

Claim 5

In an electric motor-controlled lamp as in claim 1, a stop lever pivotally mounted for rotation about said first axis, first and second stops defined on said support member in radial alignment with said lever, said stops being angularly displaced from each other with respect to said first axis and a third stop fixed with respect to said pedestal in radial alignment with said lever whereby said stops limit rotation of said support member relative to said pedestal about said first axis and the angular spacing of said first and second stops permits rotation of said support member about said first axis through more than 360°.

Claim 6

In an electric motor-controlled lamp as in claim 1, a torsion spring mounted on said support member disposed about said second axis having an end connected to said housing and imposing a biasing force on said housing tending to pivot said housing about said second axis and counterbalance said housing.

Claim 7

An electric motor-controlled lamp comprising in combination, a pedestal having a longitudinal axis and an .Iadd.unsupported free .Iaddend.end, gear support means affixed to said pedestal axially extending from and beyond said end, a first gear mounted upon said gear support means having an axis .[.substantially parallel.]. .Iadd.coaxial with .Iaddend.said pedestal axis, a support member rotatably circumscribing said support means interposed between said first gear and pedestal end and rotatable in a plane substantially perpendicular to said pedestal axis, a hollow lamp housing, means mounting said hollow lamp housing upon said support member for pivotal movement about an axis substantially perpendicular to the axis of rotation of said first gear, a second gear within and connected to said housing concentric to said housing pivot axis, first electric motor and speed reduction drive means mounted upon said support member within said housing having a pinion gear in operative engagement with said first gear, second electric motor and speed reduction drive means mounted upon said support member within said housing .Iadd.and adjacent said first motor and drive means .Iaddend.having a pinion gear in operative engagement with said second gear, an electric lamp mounted upon said housing and control means associated with said drive means.

Claim 8

An electric motor-controlled lamp comprising in combination, a pedestal having a longitudinal axis and an .Iadd.unsupported free .Iaddend.end, gear support means affixed to said pedestal axially extending from and beyond said end, a first gear mounted upon said gear support means having an axis .[.substantially parallel.]. .Iadd.coaxial with .Iaddend.said pedestal axis, a support member rotatably circumscribing said support means interposed between said first gear and pedestal end and rotatable in a plane substantially perpendicular to said pedestal axis, a hollow lamp housing, means mounting said hollow lamp housing upon said support member for pivotal movement about an axis substantially perpendicular to the axis of rotation of said first gear, a second gear within and connected to said housing concentric to said housing pivot axis, first electric motor and speed reduction drive means mounted upon said support member within said housing having a pinion gear in operative engagement with said first gear, second electric motor and speed reduction drive means mounted upon said support member within said housing .Iadd.and adjacent said first motor and drive means .Iaddend.having a pinion gear in operative engagement with said second gear, an electric lamp mounted upon said housing and control means associated with said drive means.

Claim 9

In an electric motor-controlled lamp as in claim 6, a first friction clutch connecting said first gear to said pedestal, a second friction clutch connecting said second gear to said housing, each of said friction clutches including predetermined frictional force producing means to frictionally connect said clutches to its associated gear.

Claim 10

In an electric motor-controlled lamp as in claim 6, a first friction brake interposed between said support member and said pedestal braking rotation of said support member about said first axis, and a second friction brake interposed between said housing and said support member braking rotation of said housing about said second axis, said friction brakes dampening vibrations occurring between the relatively rotating components thereof.

Claim 11

In an electric motor-controlled lamp as in claim 6, a stop lever pivotally mounted for rotation about said first axis, first and second stops defined on said support member .[.in axial alignment with.]. .Iadd.radially outward of said first axis and in the path of .Iaddend.said lever, said stops being angularly displaced from each other with respect to said first axis and a third stop fixed with respect to said pedestal .[.in axial with.]. .Iadd.radially outward of said first axis and in the path of .Iaddend.said lever whereby said stops limit rotation of said support member relative to said pedestal about said first axis and the angular spacing of said first and second stops permits rotation of said support member about said first axis through more than 360°.

Claim 12

An electric motor-controlled lamp comprising, in combination, a lamp supporting pedestal, an electric lamp mounted upon said pedestal, pivot means mounting said lamp on said pedestal for movement in a horizontal plane and in a vertical plane, a floodlight filament within said lamp, a spotlight filament within said lamp, variable speed electric motor means connected to said lamp for pivoting said lamp in said horizontal and vertical planes, switch means connected to said electric motors and switch means selectively controlling said filaments, said control means including a resistor selectively connected in series with said electric motors and said switch operating said spotlight filament whereby a reduced voltage is supplied to said motors upon energizing said spotlight filament.
