Abstract: 1521626 Boring earth &c RUSTON-BUCYRUS Ltd 5 July 1976 [19 Sept 1975] 27914/76 Heading E1F [Also in Division B3] In a handling device for a drill rod, e.g. a carousel-type rack 10, the drill rod 11 has a holding portion 52, a portion 56 of reduced diameter below the holding portion 52, and flats 55 below the holding portion 52, the device including a support plate e.g. the upper plate 42 of the rack 10, the plate 42 having a cutout 43 defining at least one set of opposite parallel straight surfaces 46 to receive the flats 55 and hold the rod 11 against rotation, the plate 42 also carrying retaining means e.g. a collar 44 to receive the holding portion 52 and having an outward opening 45 at least as large as the reduced portion 56 of the rod 11 but smaller than the holding portion 52, so that the rod 11 is laterally movable with respect to the plate 42, such as on connection or disconnection in a drill string, only when the rod 11 is raised to bring the reduced portion 56 in line with the plate 42 and collar 44. As shown, each cutout 43 has another set of parallel surfaces 47 to allow limited rotation for providing a breakout impact when disconnecting. The carousel also has a lower support plate 32 carrying cylindrical sockets 38 which are a loose fit around the bottom of the rods 11. The sockets 38 and lower ends of the rods 11 are provided with indicating holes 39, (57) that enable the operator to determine the rotational position of the rod 11, so that flats 55 engage surfaces 46 prior to breakout, and the vertical position of the rod 11, so that the rod can be laterally moved and to indicate a suitable position for the start of unthreading and when such unthreading is completed. To align a rod 11 or a space therefor with a rotary head or drill string, an indexing pin 37 is passed through one of six equally spaced indexing holes 34 in the plate 32 into a sleeve 35. The rack 10 also has a lock ring 73 carrying lobes 76 which in the locked position bear against the shoulders defined below the reduced portions 56 of the rods 11, thus preventing forward axial movement of the rods 11 when the rack is horizontal, such as when being transported on a vehicle. The lobes 76 are moved into and out of engagement with the shoulders by rotating the ring 73. A suitable operating mechanism, which may be locked in either position, is described. The rack 10 may be attached to the mast of a mobile rotary drilling rig which also includes a conventional breakout table, holding wrench, and breakout wrench.

A filter unit in an internal combustion engine lubricating-oil system comprises a cylindrical container or casing 1 having end caps 3, 4, a pleated paper filter element 5, a screw-threaded spigot 10 to engage with a bore 15 through which oil is fed to the filter unit from the engine, a stiffener plate 11 provided with one or more oil outlet openings 12 to communicate with an outlet opening or passage 19 leading to an oil sump (not shown), and a gasket 21 made of rubber, or the like, to bear against a mount face 16 on the engine. The spigot 10 includes a passage 17 having a pressure-reducing restrictor opening 20 at its inlet end, and a bleed passage 18 to communicate with the passage 19 ; the passage 17 may also have a further pressure-reducing restrictor opening 20a at its outlet end. The upper and lower ends of the element 5 are sealed by an adhesive 7 applied to adjacent pleats. The central opening in the element is closed at its ends by an annular gasket 8 surrounding a flange 9 on the spigot, and by a resilient gasket 6 attached to the end cap 4. Owing to the pressure reduction at the openings 20, 20a a proportion of the oil entering the passage 17 is diverted through the passage 18, the remainder of the oil passing through the element 5 and the openings 12. The end cap 4 is yieldable such that it and the gasket 6 are deflected downwardly, Fig. 2 (not shown), to allow the oil to by-pass the element 5 if the element and the passage 18 become choked. The container 1 is made from sheet metal, the seams being rolled in a known manner. The spigot 10 and the plate 11 are welded together at the flange 9, the plate being secured to the cap 3, e.g. by welding. The gasket 6 may be square in shape, and the ends of the element 5 may be sealed by caps (not shown). In an alternative arrangement, Fig. 3, the oil is fed to the filter unit through the passage 19 and the openings 12, and is discharged through the passages 17, 15, the flow of oil through the element 5 being radially inwards. Pressure reduction is produced by a restrictor opening 31 in a plug 30 inserted in the passage 19. In a further alternative arrangement, Fig. 4 (not shown), the construction of the filter unit is similar to that shown in Fig. 1, excepting the spigot 10 which is replaced by a female screw-threaded connector member to engage with a complementary connector secured in the passage 15 and including a restrictor opening and passages similar to those in the spigot.
