Abstract An apparatus for synchronizing movement of a camera with movement of an object to be photographed. The synchronizing apparatus includes a horizontal track which is disposed parallel to the path of movement of the object. A planar platform is movably mounted on the track and supports the camera. First and second pulleys are respectively aligned with the path of movement of the object and the track. An interconnecting cable is connected to the object and to the platform and passes around the first and second pulleys for causing an identical and simultaneous movement of the camera with movement of the object. In another embodiment, hydraulic cylinders and pistons are mounted on the dolly and the object and are connected in fluid flow communication for simultaneous movement in the same direction.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
85 words
An apparatus for synchronizing movement of a camera with movement of an object to be photographed to be comprising: a horizontal track disposed parallel to the path of movement of the object; means for movably mounting a camera on the track; and pressure energy transfering means, connected between the object and the camera mounting means and responsive to displacement of the object, for transfering a flow of fluid pressure upon displacement of the object to cause a direct linear displacement of the camera mounting means.
Claim 2
Independent Claim
85 words
An apparatus for synchronizing movement of a camera with movement of an object to be photographed to be comprising: a horizontal track disposed parallel to the path of movement of the object; means for movably mounting a camera on the track; and pressure energy transfering means, connected between the object and the camera mounting means and responsive to displacement of the object, for transfering a flow of fluid pressure upon displacement of the object to cause a direct linear displacement of the camera mounting means.
Claim 3
Dependent Claim
145 words
The apparatus of the claim 1 wherein the pressure energy transfering means comprises: first and second fluid-operated cylinder means, each having a movable piston with a rod mounted thereon, one end of each rod of the first and second cylinder means being extensible and retractable within the first and second cylinder means; one end of the rod of the first cylinder means being connectable to the object; one end of the rod of the second cylinder means being connected to the means for movably mounting the camera on the track; and means for connecting the first and second cylinder means in fluid flow communication such that displacement of the piston and rod of the first cylinder means upon movement of the object causes movement of the piston and rod of the second cylinder means resulting in a direct linear translation of the camera mounting means.
