The pocket is held in open position while being filled by means of a springclamp l1k to. form 2 near its upper end. When so filled, the upper and heretofore free end of the fabric is released from clamp 11 and drawn in, compressed and sealed by a second anged bushing 12, identical with the bushing 8 at the other end of the tube.
The element is then completed and may be removed from the cup 2 and stud 4 and is ready for use. This deleterious substances are collected and absorbed within matter prlnted In ltallcs indicates the additions ndelylehse.
The present invention relates to oil conditioners and oil puriers for use particularly with internal combustion engines; this application being a continuation in part of our copending application, Serial Number 258,653, filed `February 27, 1939, now Patent No. 2,314,640, issued relatively free flowing and exible, thus= providing a construction which permits a maximum flow rate through the element for the purpose of bringing the fluid to be filtered and processed into contact with the materials in the element for the, purpose of changing the nature of i deleterious substances contained in the lubricating oil,
fuel oil or other fluids to be reconditioned and cleaned. A further object is the provision of a exible hollow casing, preferably of tubular `form and composed of knitted materials incasing combined and mixed fibrous and porous materials, such as cotton and wood bers, into a knitted tube, with a novel means of closing the ends of the filled tube in conjunction with a central, hollow, perforate, rigid supporting member by which the filtering material, packed within the tube, is prevented from collapse.
Referring to the accompanying drawing:
Fig. l is a vertical section of a form used in the manufacture of our conditioning element.
Fig. 2 is a vertical section, illustrating the early stage of constructing our element.
Fig. 3 shows the element in incomplete state in the filling form of Fig. l, ready for filling.
Fig. 4 is a vertical, central section of the completed element constituting the present invention.
Fig. 5' illustrates, in partial section, a suitable container for the present invention, the latter being shown in partial section to denote the mode of use.
Referring to the drawing, 2 represents a cylindrical metal cup or hollow form, with a bottom 3 from which springs a central stud 4 coaxial with the cup. 5 is -a' perforated, flanged tube, substantially the length of the finished article and large enough to be slipped readily over the stud 2. 6 is a porous knitted sleeve of fabric which is slipped over the tube 5, with one end tucked into the tube, as at 7, and tightly held there by means of a flanged hollow stopper or bushing 8 which telescopes with a tight friction fit the tube 5 and clamps the fabric against the flange 9 of the tube 5.
With the fabric thus firmly secured at one end to the tube S, the latter, with the fabric sleeve, is placed in the form 2, over the stud 4, preparatory to the fabric casing 6 being filled and stuffed with a compacted mass of `out free when the cover is removed.
the body of the element. VIt is thus evident that the exterior surface is expanded and the interior is compressed at the core. Experience has taught us thatthis action is best obtainedby causing the oil to flow from the entire exposed exterior surface of the element toward a common-center. In this case the growing action which causes swelling of the element body naturally opens up the porosity on the exterior surface which not only prevents clogging of the outside surface but also continually presents new exposed surfaces of the unused chemically treated purifying materials within the body of the element itself. Y
The element as thus completed consists of a cylindrical structure of a predetermined compacted mass of filtering material surrounding a rigid hollow perforated support which is open from end to end.
wherein in our earlier application, above referred to, we have stressed a conditioning element `employing two plies of fabric, in the present instance it is noted that we have a single ply which for certain conditions is found to be ample.
The mode of use is illustrated in Fig. S, in which A5t) indicates a suitable container in the form of a cylindrical shell with a bottom fitting 51. 52 designates a removable cover, held in place by a central hollow stud 53, to which is attached a handle 54. An oil inlet 55 and an outlet 56 are provided in the fitting 51 which also provides a threaded portion 58, into which the hollow central stud 53 is threaded. A spring 60 is provided which insures an even upward pressure on the washer 61 below the element 62 which constitutes the invention above described. In some installations it is desirable to screw the hollow stud 53 rigidly into the bottom fitting 51 and screw off the handle part 54 to remove the cover when changing elements. ln other cases it may be desirable to attach rigidly the handle part 54 to the central tube and unscrew the assembly from the bottom fitting 51 when changing elements. In either case the compression spring 60 kicks out the used clement when the cover is removed.
With the filtering element housed in such a container, it is always clear of the shell and also free'of sludge during its normal life. It will be above the shell and can come In view of the fact that the novel structure of the element actually grows or expands in service and also since common crankcase sludge, when broken down into its simpler forms of materials, occupies considerable less space, the element is many times greater in both clean-up rate and long life.
