Apparatus for stereoscopic photography

Claim 2

Apparatus for taking stereoscopic pictures comprising a frame, a carriage slidably mounted along a line on said frame, a bar pivotally mounted about a point on said carriage to enable pivoting thereof to positions on either side of said line, a camera mounted on one end of said bar, a support for the object to be photographed movable along said line to bring the object into focus with the camera, said carriage being movable to vertically align the pivot point with a point predetermined with respect to the object to be photographed, said alignment automatically fixing the arc of a circle along which the camera moves, whereby exposures taken from two symmetrical positions on opposite sides of said line will provide a three-dimensional effect, and an object indicator movable along the frame interconnected for movement with said pivot point whereby aligning said indicator with said predetermined point will vertically align said pivot point with said predetermined point.

Claim 3

Claim 5

Apparatus for taking stereoscopic pictures comprising a frame, carriage means slidably mounted along a line on said frame, a bar slidably movable and pivotably mounted about a point on said carriage means to enable pivoting thereof to positions on either side of said line, a camera mounted on one end of said bar, and a support for the object to be photographed movable along said line to bring the object into focus with the camera, said carriage means being movable to vertically align said pivot point with a point predetermined with respect to the object to be photographed, said alignment automatically fixing the arc of a circle along which the camera moves, whereby exposures taken from two symmetrical positions on opposite sides of said line will provide a three-dimensional effect, said carriage means comprising a pivot carriage, a plate mounted on said pivot carriage for rotation about said pivot point, and a pair of vertical members projecting from said plate and spaced to form a channel for slidably supporting said bar, one of the said vertical members projecting from said plate being movable against said bar with means to lock said one member against said bar and secure said bar against movement within the channel at any desired position, said locking means comprising a rotatable offset cam affixed to the plate adjacent the movable member, and a lever affixed to the cam to rotate said cam and force the offset portion of the cam against the movable member.

Claim 6

Apparatus for taking stereoscopic picture comprising a frame, carriage means slidably mounted along a line on said frame, a first bar slidably movable and pivotably mounted about a point on said carriage means to enable pivoting thereof to positions on either side of said line, a camera mounted on one end of said first bar, and a support for the object to be photographed movable along said line to bring the object into focus with the camera, said carriage means being movable to vertically align the pivot point with a point predetermined with respect to the object to be photographed, said alignment automatically fixing the arc of a circle along which the camera moves, whereby exposures taken from two symmetrical positions on opposite sides of said line will provide a three-dimensional effect, said carriage means comprising a pivot carriage, a plate mounted on said pivot carriage for rotation about said pivot point, a channel in which said first bar can slide formed by a spaced pair of vertical members projecting From said plate, one of said members being movable against said first bar to lock said first bar within said channel at any desired position, a rotatable offset cam affixed to said plate adjacent said movable member, a lever affixed to said cam to rotate said cam and force the offset portion of said cam against said movable member, a second bar slidable at an angle along said first bar and positioned to exert pressure against said lever, whereby movement of said second bar will rotate said cam and lock said first bar between said projecting members.

Claim 7

Apparatus for taking stereoscopic picture comprising a frame, carriage means slidably mounted along a line on said frame, a first bar slidably movable and pivotably mounted about a point on said carriage means to enable pivoting thereof to positions on either side of said line, a camera mounted on one end of said first bar, and a support for the object to be photographed movable along said line to bring the object into focus with the camera, said carriage means being movable to vertically align the pivot point with a point predetermined with respect to the object to be photographed, said alignment automatically fixing the arc of a circle along which the camera moves, whereby exposures taken from two symmetrical positions on opposite sides of said line will provide a three-dimensional effect, said carriage means comprising a pivot carriage, a plate mounted on said pivot carriage for rotation about said pivot point, a channel in which said first bar can slide formed by a spaced pair of vertical members projecting From said plate, one of said members being movable against said first bar to lock said first bar within said channel at any desired position, a rotatable offset cam affixed to said plate adjacent said movable member, a lever affixed to said cam to rotate said cam and force the offset portion of said cam against said movable member, a second bar slidable at an angle along said first bar and positioned to exert pressure against said lever, whereby movement of said second bar will rotate said cam and lock said first bar between said projecting members.

Claim 8

The apparatus of claim 4 wherein there is an alignment device comprising a pair of transverse spaced strips secured to the frame adjacent the camera mount and extending in a direction transverse to said line, a rotatable elliptical cam affixed to said first bar and disposed between said strips, said cam having a narrow dimension small enough to pass freely between the spaced strips and a large dimension greater than the distance between the spaced strips, whereby rotation of said cam will force the wide portion of said cam against the strips and align said first bar along said line.

Claim 9

Apparatus for taking stereoscopic pictures with a single lens camera comprising a frame a carriage slidably mounted along a line on said frame, a bar pivotally mounted about a point on said carriage to enable pivoting thereof to positions on either side of said line, a camera mount supported on said bar and spaced from said pivot point, a support on which an object can be placed to be photographed, said support being movable along said line to bring an object on the support into focus with a camera affixed to said camera mount when the said camera is positioned on said mount in front of the boject to be photographed on said support and on said line, said pivot point being movable along said line to align the pivot vertically with a predetermined point behind the object to be photographed, said alignment automatically fixing the arc of a circle through which the camera moves, whereby exposures taken from two symmetrical positions on opposite sides of said line will provide a three-dimensional effect, and an object indicator movable along the frame interconnected with the movable pivot point whereby aligning said indicator with said predetermined point will vertically align said pivot point with said predetermined point behind the object.

Claim 10

Apparatus for taking stereoscopic pictures with a single lens camera comprising a frame a carriage slidably mounted along a line on said frame, a bar pivotally mounted about a point on said carriage to enable pivoting thereof to positions on either side of said line, a camera mount supported on said bar and spaced from said pivot point, a support on which an object can be placed to be photographed, said support being movable along said line to bring an object on the support into focus with a camera affixed to said camera mount when the said camera is positioned on said mount in front of the boject to be photographed on said support and on said line, said pivot point being movable along said line to align the pivot vertically with a predetermined point behind the object to be photographed, said alignment automatically fixing the arc of a circle through which the camera moves, whereby exposures taken from two symmetrical positions on opposite sides of said line will provide a three-dimensional effect, and an object indicator movable along the frame interconnected with the movable pivot point whereby aligning said indicator with said predetermined point will vertically align said pivot point with said predetermined point behind the object.
