Abstract
Abstract A panner for a camera or the like has a base on which is mounted a housing carrying a support for the camera or the like mounted above the housing. Drive means serve to rotate the housing relate to the base about a first axis so that the camera may be clamped about this axis. The support is pivotal above a second axis which is perpendicular to the first axis. An arm extends from the support into the housing and second drive means serve to reciprocate the end of the arm distal of the support and to rotate this support about the second axis.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
254 words
An electrically operated panner for a camera or the like comprising a base, a housing mounted on said base, first and second drive means wholly contained within said housing, said first drive means comprising an electric motor including a motor shaft, said motor being fixed relative to said housing, a worm on said motor shaft, a first wormwheel in mesh with said worm, a second worm co-axial with and connected to said first wormwheel, a second wormwheel in mesh with said second worm, said second wormwheel being drivingly connected to said base and rotating said base relative to said housing about a first axis upon actuation of said motor; said second drive means comprising another electric motor including a motor shaft, said another motor being fixed relative to said housing, a worm on said motor shaft of said another motor, a first wormwheel in mesh with said worm, a second worm co-axial with and connected to said first wormwheel, a second wormwheel in mesh with said second worm, a first are eccentrically mounted on said second wormwheel which moves arcuately on rotation of said second wormwheel, a support for said camera or the like mounted above said housing and pivoting about a second axis perpendicular to said first axis; and a second arm extending from said support into said housing, the distal end of said second arm being drivingly connected to the distal end of said first arm and which upon actuation of said second drive means rotates said support about said second axis.
Claim 2
Dependent Claim
254 words
An electrically operated panner for a camera or the like comprising a base, a housing mounted on said base, first and second drive means wholly contained within said housing, said first drive means comprising an electric motor including a motor shaft, said motor being fixed relative to said housing, a worm on said motor shaft, a first wormwheel in mesh with said worm, a second worm co-axial with and connected to said first wormwheel, a second wormwheel in mesh with said second worm, said second wormwheel being drivingly connected to said base and rotating said base relative to said housing about a first axis upon actuation of said motor; said second drive means comprising another electric motor including a motor shaft, said another motor being fixed relative to said housing, a worm on said motor shaft of said another motor, a first wormwheel in mesh with said worm, a second worm co-axial with and connected to said first wormwheel, a second wormwheel in mesh with said second worm, a first are eccentrically mounted on said second wormwheel which moves arcuately on rotation of said second wormwheel, a support for said camera or the like mounted above said housing and pivoting about a second axis perpendicular to said first axis; and a second arm extending from said support into said housing, the distal end of said second arm being drivingly connected to the distal end of said first arm and which upon actuation of said second drive means rotates said support about said second axis.
Claim 3
Dependent Claim
16 words
A panner as claimed in claim 1 wherein each worm is biassed towards a respective wormwheel.
Claim 4
Dependent Claim
24 words
A panner as claimed in claim 1 wherein a friction clutch is provided in the first drive means between the housing and the base.
Claim 5
Dependent Claim
24 words
A panner as claimed in claim 2 wherein a friction clutch is provided in the first drive means between the housing and the base.
Claim 6
Dependent Claim
65 words
A panner as claimed in claim 3 wherein the friction clutch comprises a wavy washer compressingly sandwiched between first and second plates, the first plate being drivingly connected to the second wormwheel of the first drive means and the second plate being drivingly connected to the base, whereby manual rotation of the base relative to the housing takes place without rotation of the second wormwheel.
Claim 7
Dependent Claim
65 words
A panner as claimed in claim 4 wherein the friction clutch comprises a wavy washer compressingly sandwiched between first and second plates, the first plate being drivingly connected to the second wormwheel of the first drive means and the second plate being drivingly connected to the base, whereby manual rotation of the base relative to the housing takes place without rotation of the second wormwheel.
Claim 8
Dependent Claim
61 words
A panner as claimed in claim 1 in which the first arm has a pin on the distal end thereof and the distal end of the second arm is bifurcated, the pin being located in the bifurcated end of said second are and drivingly connecting the second wormwheel of the second drive means to the distal end of said second arm.
Claim 9
Dependent Claim
62 words
A panner as claimed in claim 1 wherein the first drive means is mounted on a platform located in and attached to the housing, the electric motor of said first drive means being mounted about said platform, the first and second worms and first and second wormwheels being mounted below said platform, and the second drive means being mounted above said platform.
Claim 10
Dependent Claim
25 words
