    Abstract: 796,475. Oil filters. FRAM CORPORATION. Oct. 18, 1956 [March 1, 1956], No. 31735/56. Class 46. [Also in Group XXII] An oil filter of the screw-on, throw-away type comprises a cup-shaped shell having an end wall and integral side walls extending the entire length of the shell and supporting the entire fluid pressure on the end, a sheet metal closure for the other end of the shell sealed to the side walls, a filter cartridge within the shell, and a reinforcing plate inside the shell and contacting the closure, the plate having a central opening surrounded by internal threads by which it may be screwed on to a projection to secure the filter in its operative position. A cup-shaped casing 10 locates within itself, by ribs 12, a flange 17 on an end plate 15 secured to a pleated filter 14 surrounding a perforated tube 19 the upper end of which encircles a cover 21 supporting a spring 22 and carrying a by-pass valve 48. The spring presses the filter down on to a thick metal reinforcing plate 27 which abuts the wall of the casing 10 to provide a backing when a turned over joint 25, 26 is made between the casing and an end wall 24. The centre of the plate 27 is formed as a screwed sleeve 28 to adopt the casing to be screwed on to a bush 34 whose upper end 35 engages a bottom cover 23 for the tube 19 to lift the filter off the plate 27 and thereby provide a passage for oil to the exterior of the pleats 14. Oil enters this passage through ports 42 in the plate 27, these ports co-operating with ports 41 in an adaptor plate 37 which makes fluid tight contact with the plate 27 through a packing ring. The space beneath the adaptor plate 37 communicates with an annular recess 32 in the engine block of an internal combustion engine, a conduit 30 connecting the recess with the oil sump. A plate 46 having a single aperture 47 divides the space beneath the adaptor 37 to prevent loss of oil if the filter unit is mounted in a tilted position. The bush 34 is hollow and connects the central tube 19 with a passage 31 in the block 29 and leading to the engine bearings. A flange 36 on the bush 34 clamps the adaptor plate 37 and plate 42 to the block 29. The reinforcing plate may be flat and a packing ring be disposed in an outwardly facing recess in the end wall 24 ; a flat disc of rubber lies on the plate 27 above the ports in the plate to form a non-return valve which prevents escape of oil from the filter.

    Abstract: 753,439. Filters. FRAM CORPORATION. Dec. 6, 1954 [Jan. 4, 1954], No. 35246/54. Class 46. In an apparatus for separating two immiscible liquids having different surface tensions comprising a casing 10 which is closed at one end 11 and has a removable head 13 closing its other end and provided with an inlet chamber 14 and an outlet chamber 15, one or more coalescer cartridges 34 are secured to the head to communicate with the inlet chamber and extend into the casing, and one or more separator cartridges 33 are secured to the head to communicate with the outlet chamber and extend into the casing, a pipe 16 supplying the liquid to be separated to the inlet chamber from whence it passes outwardly through the coalescer cartridge(s) 34 to the separator cartridge(s) 33, the walls of which hold back one liquid and permit the other liquid to pass inwardly through the walls to the outlet chamber 15 and dischargepipe 18. The coalescer cartridges 34 comprise a perforated inner metal tube 43 about which is provided a combined filter and coalescer 44 of pleated paper enclosed in a perforated outer metal tube 45. The inner tube 43 is provided with a coil re-inforcing spring 52. The folded paper cylinder 44 may have around it a batt 53 of fine fibre glass. The separator 33 is preferably constructed as described in Specification 736,917 and comprises a plurality of cells 35 formed of paper discs secured one to the other with their central openings in axial alignment. The cartridge is enclosed in a perforated metal tube 36. Specification 657,601 also is referred to.
