Abstract
Abstract Suspension apparatus is disclosed for holding an X-ray film cassette frame. The apparatus includes clamping means attachable to a suitable support and or a series of independently adjustable arms providing a support for the cassette frame. The arms are adapted for adjustment variously in horizontal and vertical planes with reference to the mounting position of the clamping means and cooperate to extend and retract relative to said clamping means. Thus the cassette frame can be moved through included angles of 360° in both the horizontal and vertical planes and can be extended and retracted between the clamping means and a subject to be photographed. In practice with the present invention it is possible to X-ray a wide variety of different areas of a patient while permitting the subject to remain immobile by adjusting the X-ray film in the cassette to accommodate the position of the immobile patient.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
185 words
Suspension apparatus for an X-ray film cassette frame comprising a clamping member for rigid attachment to a supporting element, a projection rigidly attached to said clamping member, a first arm connected to said projection for pivoting movement in a first plane through a path of approximately 220°, a second arm connected with said first arm and pivotable in a second plane through a path of more than 180°, a third arm connected with said second arm and pivotable in said second plane through a path of generally 360°, a fourth arm connected with said third arm and pivotable in said second plane through a path of generally 360°, a link connected with said fourth arm and pivotable in said first plane through a path of approximately 360°, coupling means connecting an X-ray film cassette frame with said link, and means for securing said projection, said first, second, third and fourth arm, and said link in preselected positions to thereby dispose said film cassette frame in any desired position along a 360° arc of said first path and along a 360° arc of said second path.
Claim 2
Dependent Claim
185 words
Suspension apparatus for an X-ray film cassette frame comprising a clamping member for rigid attachment to a supporting element, a projection rigidly attached to said clamping member, a first arm connected to said projection for pivoting movement in a first plane through a path of approximately 220°, a second arm connected with said first arm and pivotable in a second plane through a path of more than 180°, a third arm connected with said second arm and pivotable in said second plane through a path of generally 360°, a fourth arm connected with said third arm and pivotable in said second plane through a path of generally 360°, a link connected with said fourth arm and pivotable in said first plane through a path of approximately 360°, coupling means connecting an X-ray film cassette frame with said link, and means for securing said projection, said first, second, third and fourth arm, and said link in preselected positions to thereby dispose said film cassette frame in any desired position along a 360° arc of said first path and along a 360° arc of said second path.
Claim 3
Dependent Claim
29 words
Apparatus as set forth in claim 1 wherein said suspension arms are arranged for cooperative articulation to move said cassette frame longitudinally toward and away from said clamping member.
Claim 4
Dependent Claim
