Abstract
827,664. Mandrels. STRACHAN & HENSHAW Ltd. Sept. 6, 1957 [Nov. 9, 1956], No. 34378/56. Class 83 (3). A mandrel comprises a tube 11, Fig. 1, sealed at the ends by plugs 12, 14 and seals 13, 15. The tube has a number of diametricallyopposite apertures 17, each of which has a flanged rubber diaphragm 18 secured therein, by a flange 19 located in an annular groove 20 in the aperture 17. A spring 24 abuts shoulders 25 of each pair of sleeves 22, urging them towards the diaphragms so that ends 23, of sleeves 22, enter recesses 21 of the diaphragms to prevent accidental removal thereof. In use, work such as a tube 26, placed on tube 11, is held by pressure applied through a valve 16 in the plug 14, which deforms the diaphragms 18, Fig. 3, into contact with the inner-face of tube 26. In a modification, a spring 24 is arranged inside each pair of sleeves 22, which are flanged to engage the spring-ends and the inner-rims of the diaphragms 18.
