Patent GB-551894-A (GB)
Abstract: 551,894. R÷ntgen-ray apparatus. GOLDFIELD, E. R., and GRAVES, E. B. Sept. 11, 1941, No. 11650. [Class 98 (i)] An X-ray apparatus having a tilting table and fluoroscopic screen unit comprises a tube stand including a carriage movable on the table and supporting a column at one side of the table and extending beyond the table face, and a pillar which is adapted to support the tube and is pivotably mounted on said column on a horizontal axis. As shown, a carriage formed by rods 9 and end members 10 is provided with antifriction rollers engaging tracks 12 on the underside of a tilting table, so as to be adjustable lengthwise of the table. A sub-carriage formed by rods 15 and end members 16, 17 is adjustable on the first carriage transversely of the table, the head 17 carrying a pillar 28 on which are mounted the members supporting the tube and fluorescent screen. The carriages and parts carried by them are counterbalanced, when the table is tilted or vertical, by an elongated counterweight (not shown) provided with anti-friction rollers travelling on longitudinal guideways below the table, cables connecting the counterweight to the member 10 of the carriage. The tube is carried by the outer end of an arm 29 mounted in a head 40 carried by the pillar 28 which is slidably mounted in a casing 38 pivotally mounted on a head 31 carried by the column 27. The pillar 28 and the parts carried by it are counterbalanced by a spring 42 connected to a cable passing round a drum having a tapered portion 46 on which is wound a second cable attached to the casing 38, whereby the balancing force of the spring is rendered constant. When the casing 38 is rotated about the axis A-A to move the tube to the opposite side of the table, the spring 42 moves the pillar 28 to its full outward position as it approaches the horizontal, so carrying the tube clear of the end of the table. A spring 35 connected to an eccentric pin on the rotary member 32b carrying the casing 38 counterbalances the pillar 28 and the parts carried by it during its rotary movement and tends to maintain it in either of its extreme positions. The fluorescent screen is carried by an arm 57, Fig. 11, journalled in a member 56 pivoted at 55 in a hollow head 51 which is journalled in an arm extending from the head 31. The screw is counterbalanced by a spring 65 operating on the member 56 through a lever 67 which may be disengaged from it by hand when the table is moved to the vertical position and the counterbalance is therefore not needed.
