1,170,303. Holder for X-ray film cassettes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 July, 1967 [9 July, 1966], No. 31124/67. Heading H5R.. A cassette holder comprises a pair of generally parallel clamping members 5, 6 contrained on framework 1, 2, 3, 4 to move towards and away from each other and between which the cassette 10 can be held, a lever 1.5 pivotable about a spindle 14, each arm 16, 17 of the lever being attached, e.g. by links 18, 19, to a corresponding clamping member, a pivot arm 13 pivotable about the same spindle and secured to the lever by a first tension spring, e.g. 21, a second tension spring, e.g. 29, secured between the lever and a point fixed relative to the clamping members, this spring being active in a direction to oppose the pivotal movement of the lever and means for retaining a cassette when introduced into the holder, the arrangernent being such that when a cassette 10 is introduced between members 5 and 6 causing displacement of the pivot arm 13, the lever rotates so that the clamping members move towards each other simultaneously and to the same extent. Preferably when there is no cassette in the holder the spring 21 tends to hold the pivot arm against an abutment 20 on the lever, and the cassette retaining means comprises a spring-biased locking mechanism 24, 25, 26, 27, 28 connected to one clamping member, e.g. 6, having a catch 25 to retain a cassette introduced into the holder against the impulse of spring 29 to eject it, which ejection occurs when the catch 25 is released. Clamping members 5 and 6 may be fitted with guide members 7 and 8, and with wheels 9 to slide on the framework. The free end of arm 13 is fitted with a roller 22 to contact the inserted cassette.
