971,254. Clamp fastenings. D. H. GOLDTHORP. Jan. 2, 1961 [Jan. 1, 1960], No. 82/60. Headings E2A and E2B. A cassette holder comprises a double clamp component 1 adapted to be adjustably mounted on a fixed support 6 and a single clamp component 2 carried by the double clamp component through the intermediary of a secondary support 3 of elbow form, the single clamp component being adapted to carry the cassette 4. As shown a frame 5 is attached to the single clamp component to carry the cassette, the frame 5 comprising an end member 21, two diagonal members 22 extending from the ends of the member 21 to the clamp component, a central channel shape member 24 and a slidable member 25, engaged in the channel shaped member 24, both the slidable member 25 and the member 21 having recesses to engage the cassette. The slidable member is loaded by a spring (not shown) and a detent 28 is provided to adjust its position, this detent engaging one of a plurality of slots 30. The double clamp component 1 includes a sliding jaw clamp, the jaws of which 16, 17 are urged together by a threaded member 12 and also includes a T-piece 7 having a bore 8 which slides on the fixed support, the T-piece 7 being fixed in any desired position by a clamping member 9. A pin 11 extends from the T-piece 7 through the jaws 16, 17 and between the jaw 16 and the T-piece is a fibre washer 13 so that when the threaded member 12 is rotated on a threaded end of the pin 11 not only are the jaws 16, 17 urged together but the fibre washer is compressed to clamp the jaw 16 in any desired position relative to the T-piece 7. The jaws of the clamp component 2 are similar to those of the clamp component 1 and they are similarly attached to a base member with a similar fibre washer between the rear jaw and the base member. The base member carries the frame 5.
