The grinding-wheel 11 is secured on the end of a spindle 5, which is made in sections engaged together as shown in Figs. 6 and 7, and is enclosed in a tube 3, which may be made in sections coupled together by screwed sleeves 4. At the junction, the spindle is supported by ball bearings, the outer races 8 of which are nipped between the tube sections; the inner surfaces of these races have curved contours to allow the shaft to aline itself. The grinding-wheel end of the spindle is supported in a floating bearing 15 having spherical shoulders on a central collar, which engage in a corresponding annular recess in a socket screwed into the end of the tube 3. To compensate for wear, the socket is formed in two lengths 12, 13, Fig. 3, each providing one of the curved surfaces of the recess; these are formed on their adjacent ends with inter-engaging teeth. By taking out the socket, disengaging the teeth, and then re-engaging them with one part advanced relatively to the other, the socket, when screwed back into the tube, will have the bearing-surfaces drawn slightly nearer together. The tube 3 forms an oil bath, and adjacent to the collar 21 on the spindle a coiled helical spring 20 is disposed; the end of the bearing 15 next to the collar is formed with a series of notches or oil grooves, Fig. 4. The grinding-wheel may be provided with a sleeve 22 to prevent escape of oil. Preferably, the apparatus is enclosed in a casing 1 made in sections connected by bushes 2. The casing is mounted in a housing on the saddle of a lathe &c. at a point corresponding to the centre of gravity of the apparatus. The upper surface of the casing may be graduated to facilitate the location longitudinally of the wheel in the tube; its position transversely is controlled by a former plate. Fig. 2b shows only the grinding-wheel end of the apparatus; at the opposite end, a driving- pulley is secured on the spindle.

Abstract: 1,063,433. Sand filter. PATERON CANDY INTERNATIONAL Ltd. Jan 12, 1966 [Jan. 14, 1965], No. 1777/65. Heading B1D. In a sand filter, in which means responsive to a pressure differential between inlet and outlet flow is used to interrupt the flow, cause a backwash of a predetermined quantity of liquid, and then restore normal flow, a certain differential communicated to either side of a diaphragm (29) from inlet pipe 8 and outlet pipe 4 respectively opens a valve (27') to allow flow from pipe 4, via pipe 24 to operate valve piston 26, thus opening valve 22. With valve 22 open, water syphons from tank 5 into tank 17 where firstly float 15 is actuated to close valve 6 to interrupt the flow, and then float 16 is actuated to open valve 7 to allow backflush from the unsyphoned water in tank 5. As tank 17 then empties through pipe 19, floats 16 and 17 operate to close valve 7, and the open valve 6 to restore normal flow. Once valve 6 is fully open, and this will occur before the water level in tank 5 has risen sufficiently to start a flow through syphon 21, the pressure differential between pipes 3 and 4 will be low enough to close valve 27'.
