Abstract
Abstract A positioning mechanism for moving a film carrier in a plane along x and y coordinate axes therein. The means for supporting and moving the film carrier in said plane includes a torsion bar which facilitates accurate movement along said axes, which is necessary when the mechanism is used to produce or locate extremely small images of the photochromic type on a film. Simple controls including electrical relays and solenoids are used to control the indexing of the film carrier.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
257 words
In a reducing camera having a base, an optical axis, and a film support assembly, the improvement comprising indexing means for moving said assembly in a plane which is perpendicular to said axis and for reciprocatingly moving said assembly within said plane along first and second lines at right angles to one another, said indexing means Comprising: a pair of spaced vertical supports perpendicular to and upstanding from said base; a first slide member slidably mounted on one of said supports and a second slide member slidably mounted on the remaining said vertical support; a pair of spaced parallel rods positioned perpendicularly to said vertical supports, with each said rod having one end thereof secured to said first slide member and the remaining end thereof secured to said second slide member; said film support assembly being slidably mounted on said rods between said slide members so as to be reciprocatingly movable in sad plane along said first lines which are perpendicular to said vertical supports; first indexing means operatively connected to said film support assembly for indexing said assembly on said parallel rods along said first lines; second indexing means operatively connected to said first slide member for indexing said first slide member along one of said vertical supports, so as to index said assembly along said second lines; and torsion bar means operatively connected between said first slide member and said second slide member so as to assist in reciprocating said second slide member on its associated vertical support in parallel relationship with said first support.
Claim 2
Dependent Claim
257 words
In a reducing camera having a base, an optical axis, and a film support assembly, the improvement comprising indexing means for moving said assembly in a plane which is perpendicular to said axis and for reciprocatingly moving said assembly within said plane along first and second lines at right angles to one another, said indexing means Comprising: a pair of spaced vertical supports perpendicular to and upstanding from said base; a first slide member slidably mounted on one of said supports and a second slide member slidably mounted on the remaining said vertical support; a pair of spaced parallel rods positioned perpendicularly to said vertical supports, with each said rod having one end thereof secured to said first slide member and the remaining end thereof secured to said second slide member; said film support assembly being slidably mounted on said rods between said slide members so as to be reciprocatingly movable in sad plane along said first lines which are perpendicular to said vertical supports; first indexing means operatively connected to said film support assembly for indexing said assembly on said parallel rods along said first lines; second indexing means operatively connected to said first slide member for indexing said first slide member along one of said vertical supports, so as to index said assembly along said second lines; and torsion bar means operatively connected between said first slide member and said second slide member so as to assist in reciprocating said second slide member on its associated vertical support in parallel relationship with said first support.
Claim 3
Dependent Claim
56 words
The improvement as claimed in claim 1 in which said torsion bar means comprises a torsion bar having lever means adapted to place said bar in torsion in order to effect parallel movement of said second slide member relative to said first slide member as said first slide member is moved by said second indexing means.
Claim 4
Dependent Claim
62 words
The improvement as claimed in claim 2 further comprising a support member means positioned parallel to and spaced from said base for joining the ends of said vertical support members located away from said base; and a constant tension spring means having one end thereof secured to said support member means and the remaining end thereof secured to said second slide member.
Claim 5
Dependent Claim
67 words
The improvement as claimed in claim 3 in which each one of said ends of said vertical supports is joined to said support member means by a bearing means, said bearing means including an outer ring secured to said support member means, an inner ring in which the pertaining end of said vertical support is slidably mounted, and a metal diaphragm joining said inner and outer rings.
Claim 6
Dependent Claim
114 words
The improvement as claimed in claim 1 in which said torsion bar means comprises: a torsion bar; a first lever fixed at one end thereof to one end of said torsion bar, with the remaining end of said lever being pivotally joined to said first slide member; a second lever fixed at one end thereof to the remaining end of said torsion bar, with the remaining end of said second lever being pivotally joined to said second slide member; and lever means pivotally joined to the ends of said torsion bar and pivotally joined to said base so as to maintain the longitudinal axis of said torsion bar in parallel relationship with said rods.
Claim 7
Dependent Claim
39 words
The improvement as claimed in claim 5 in which said torsion bar is tubular, and in which said second lever has adjustable means thereon for adjustably fixing the amount of torsion in said torsion bar between the ends thereof.
Claim 8
Dependent Claim
26 words
The improvement as claimed in claim 6 in which said lever means pivotally joining the ends of said torsion bar with said base include self-centering bearings.
Claim 9
Dependent Claim
39 words
The improvement as claimed in claim 1 in which said first and second indexing means include a common control means for automatically indexing said film support assembly from a first position to a last position along said first lines.
Claim 10
Dependent Claim
62 words
The improvement as claimed in claim 8 in which said control means have means for returning said film support assembly along said first lines to a position beyond said first position and for returning said film support assembly in the direction of said last position to said first position so as to accurately locate said film support assembly at said first position.
Claim 11
Dependent Claim
53 words
The improvement as claimed in claim 8 in which said first indexing means includes a means for providing the smallest incremental advance expected to be needed of said film support assembly along said first lines, and a member cooperating therewith and adapted to alter said smallest incremental advance by whole number multiples thereof.
Claim 12
Dependent Claim
189 words
The improvement as claimed in claim 8 in which said first indexing means includes: a horizontally positioned lead screw operatively connected to said film support assembly for indexing said assembly along said first lines; a detent wheel having recesses on the periphery thereof and being fixed to said lead screw to rotate it; a programming plate having at least one recess on the periphery thereof and being detachably fixed to said detent wheel to rotate therewith; means for rotating said detent wheel under the control of said common control means; control level means operatively connected to said common control means and adapted to engage said recess on said programming plate and stop the rotation thereof; said recesses on said detent wheel being arranged to provide the smallest incremental advance expected to be needed of said film support assembly along said first lines as represented by the angular distance between adjacent recesses thereon; and said one recess on said programming plate being aligned with one of the recesses of said detent wheel and being adapted to control the rotation of said detent wheel in cooperation with said control lever means.
Claim 13
Dependent Claim
