Abstract
Abstract An X-ray radiographic or fluoroscopic table which includes as a part thereof a bucky including a frame containing a removable cassette-supporting tray, the bucky being movable in the long direction of the table and having a front opening for slidably receiving the tray, the bucky further carrying switch means operable in conjunction with switch-operating means on the tray, the switch being operable, when the tray is located in either cassette-loading or in filming position, to activate means for rendering the bucky immovable, which means is inactivated to allow the bucky to be adjusted when the tray is located at a midpoint between those positions.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
77 words
A fluoroscopic table comprising a base, a top position on said base, a bucky positioned beneath said top, operating means for moving said bucky beneath the top and longitudinally thereof, said bucky comprising a boxlike frame having a front opening and a tray slidable into and out of the frame through said opening, and means responsive to selective positioning of said tray within the frame for immobilizing said bucky selected positions of said tray within the frame.
Claim 2
Dependent Claim
77 words
A fluoroscopic table comprising a base, a top position on said base, a bucky positioned beneath said top, operating means for moving said bucky beneath the top and longitudinally thereof, said bucky comprising a boxlike frame having a front opening and a tray slidable into and out of the frame through said opening, and means responsive to selective positioning of said tray within the frame for immobilizing said bucky selected positions of said tray within the frame.
Claim 3
Dependent Claim
59 words
A table as set forth in claim 1 wherein said tray is positionable within the frame at a first station wherein a film cassette may be loaded thereon, a second station wherein an X-ray exposure may be made, and a third stage, and said immobilizing means is operable when the tray is positioned at said first or second station.
Claim 4
Dependent Claim
23 words
A table as set forth in claim 2 wherein said immobilizing means is inoperable when the tray is positioned at said third station.
Claim 5
Dependent Claim
35 words
A table as set forth in claim 1 wherein said immobilizing means comprises an electrically operated lock on said operating means, and electrical switch means located on said bucky and electrically connected to said lock.
Claim 6
Dependent Claim
42 words
A table as set forth in claim 4 wherein said bucky frame and said bucky tray each includes an effective switching area, and said areas are relatively movable into and out of switching proximity upon adjustment of the tray within the frame.
Claim 7
Dependent Claim
47 words
A table as set forth in claim 5 wherein one of said switching areas carries a switch device and the other switching area carries a switch-actuating device, said devices being relatively movable into switch-operating proximity when the tray is positioned at a selected station in said frame.
Claim 8
Dependent Claim
14 words
A table as set forth in claim 4 wherein said lock is an electromagnet.
Claim 9
Dependent Claim

A table as set forth in claim 13 wherein said bucky frame and said bucky tray each includes an effective switching area, and said areas are relatively movable into and out of switching proximity upon adjustment of the tray within the frame.
Claim 17
Dependent Claim
47 words
A table as set forth in claim 14 wherein one of said switching areas carries a switch device and the other switching area carries a switch-actuating device, said devices being relatively movable into switch-operating proximity when the tray is positioned at a selected station in said frame.
Claim 18
Dependent Claim
14 words
A table as set forth in claim 13 wherein said lock is an electromagnet.
Claim 19
Dependent Claim
48 words
A table as set forth in claim 16 wherein said frame carries a magnetically operable switch electrically connected to said electromagnet, and said tray carries a magnet which is positioned in operating proximity to the switch when the tray is positioned at a selected station within the frame.
