Abstract
Abstract A flat plane holding fixture for use in positioning X-ray cassettes and the like with respect to an X-ray camera. The fixture is characterized by its ability to center with respect to the camera cassettes of varying sizes, while determining both the cassette size and its orientation either upon a longitudinal or a transverse axis.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
A flat plane holding fixture for objects having diametrically opposed corners comprising: (A) a base plate including a first pair of aligned slots, defining selective orientation of the object being held upon a longitudinal axis and a second pair of similarly aligned slots defining selective orientation of the object being held upon a transverse axis; (B) pairs of opposed clamps slideably mounted within said pairs of aligned slots, so as to abut opposed corners of said object being held; (C) linkage pivoted at the center point intersection of longitudinal and transverse axes of said object being held and interconnecting said clamps beneath said base, so as to govern constant equidistant disposition of said clamps with respect to said center point; and (D) an electrically energized sensing circuit having: (i) at least one sensor adjacent a slot in each said pair; (ii) switch means closable, as one of said clamps abuts said sensor; and (iii) indicator means indicating closing of said switch and, thus, the size and orientation of said object.
Claim 2
Dependent Claim
170 words
A flat plane holding fixture for objects having diametrically opposed corners comprising: (A) a base plate including a first pair of aligned slots, defining selective orientation of the object being held upon a longitudinal axis and a second pair of similarly aligned slots defining selective orientation of the object being held upon a transverse axis; (B) pairs of opposed clamps slideably mounted within said pairs of aligned slots, so as to abut opposed corners of said object being held; (C) linkage pivoted at the center point intersection of longitudinal and transverse axes of said object being held and interconnecting said clamps beneath said base, so as to govern constant equidistant disposition of said clamps with respect to said center point; and (D) an electrically energized sensing circuit having: (i) at least one sensor adjacent a slot in each said pair; (ii) switch means closable, as one of said clamps abuts said sensor; and (iii) indicator means indicating closing of said switch and, thus, the size and orientation of said object.
Claim 3
Dependent Claim
31 words
A flat plane holding fixture for objects having diametrically opposed corners as in claim 1, including a plurality of said sensors, indicating both the size and orientation of objects being held.
Claim 4
Dependent Claim
62 words
A flat plane holding fixture for objects having diametrically opposed corners as in claim 2, including an electrically energized sensing circuit embodying said sensors, switch means and indicators so as to indicate use of said clamps in both said first pair of slots and said second pair of slots and, thereby, indicating, respectively, longitudinal and transverse orientation of said object being held.
Claim 5
Dependent Claim
39 words
A flat plane holding fixture for objects having diametrically opposed corners as in claim 3, said sensors indicating the distance between clamps in each said pair of slots as a factor of the size of the object being held.
Claim 6
Dependent Claim
24 words
A flat plane holding fixture for objects having diametrically opposed corners as in claim 4, said clamps being particularly adapted for holding X-ray cassettes.
Claim 7
Dependent Claim
30 words
A flat plane holding fixture for objects having diametrically opposed corners as in claim 5, including separate linkage for each said pairs of slots and pivotable at said center point.
