FILTER CARGE Eldred 1D. Sievers, Winona, Minn, assignor to Unit Manufacturing Company, Winona, Mirna, a partnership This invention relates to filter cartridges for filtering oil used in internal combustion engines and such like, and has for its principal object to provide a simple, low cost commercial filter cartridge suitable for original equipment and routine replacement.
Generally speaking, this is accomplished by slitting and bending the end portions of a tube to form spaced sets of flanges or fingers grasping and fastened to disks at each end to form a spool and winding filter material or: the spool.
In the drawings:
Fig. 1 is a longitudinal section through the filter cartridge;
Fig. 2 is an end view looking from the top of Fig. 1;
Fig. 3 is a similar view looking from the bottom of Fig. 1;
Fig. 4 is a perspective view of one end portion of the spool; and
Fig. 5 is an exploded perspective view showing the several parts of the end shown in Fig. 4 prior to assembly.
But these specific drawings and the corresponding description are used for the purpose of illustrative disclosure only, and are not intended to impose unnecessary limitations on the claims.
In the drawings, indicates a metal tube slit adjacent to each end to form two sets of alternating fingers or flanges 11 and 12.
The fingers 11 are first bent to the positions illustrated in Fig. 5. Then a large disk 13, having a circular opening which is of the same diameter as the outside diameter of the tube, is slipped over the fingers 12, against the fingers 11, and the fingers 12 are then bent up against the outer side of the disk 13.
Subsequently, a smaller disk 14 is placed against the turned up fingers 12 and concentric with the tube 10, after which fastening devices are inserted through the disks and the fingers. As here shown, those devices 15 have the appearance of familiar wire staples, though they are put in by machine, which performs an operation commonly known as metal stitching, during which a continuous wire is formed into staples, inserted, and clinched.
As shown in Figures 2 and 3, each staple 15 passes through both a finger 11 and a finger 12. This arrange-- ment brings the axially inner fingers 11 into play in resisting movement of disks 13 outward of the tube ends.
The spool thus formed is very simple, and can be produced with great uniformity at low cost.
The disks 13 and 14, together with the fingers or flanges 11 and 12, form the end walls of the spool, between which the material 16 is wound or otherwise placed. Preferably, this material is made of a laminated sheet consisting of a woven fabric and a relatively thick layer of carded waste, knitted to the fabric by booking threads of the waste through it.
After the laminated sheet is wound on the spool with tension suited to the filtering conditions, it may be covered by a knitted tube known in the trade as ham tubing, the ends of which are tucked in between the disks 13 and 14.
Such a filter cartridge lends itself to general use in oil filters, and is easy to ship, handle, and store.
When inserted into the familiar container, the tube thereof is received in the tube 10; and, when the cover is made fast, the end walls of the spool form gaskets to prevent channeling across the ends of the filter element.
In order to make the end walls suited for that purpose, the disks 13 and 14 are preferably made from so-called fiber sheet consisting of kraft paper treated with glue, glycerine, and formaldehyde, which may be had from a number of sources.
The opening 17 in the disk 14 fits the tube in the con tainer.
I claim:
1. In a spool including a tube, an end wall therefor comprising a plurality of outwardly directed fingers fixed to an end of the tube and positioned substantially perpendicular to the axis of the tube, some of said fingers being disposed in a first radial plane and the remainder of said fingers being disposed in a second radial plane spaced axially outward of the tube from the first radial plane, a first disk received between said some and said remainder of said fingers, a second disk positioned against said remainder of said fingers, and staple means securing said disks and said fingers together, said staple means comprising a plurality of metal staples passing through said disks and said fingers, each of said staples passing through both a finger of said first radial plane and a finger of said second radial plane.
2. A filter cartridge comprising a tube, said tube being formed with a plurality of perforations, a laminated sheet secured about said tube, a plurality of outwardly directed fingers integral with each end of the tube and positioned substantially perpendicular to the axis of the tube, some of said fingers of each end being disposed in a first radial plane and the remainder of the fingers of each end being disposed in a second radial plane spaced axially outward of the respective planes of said some fingers, a first disk secured between said first and second planes of fingers of each end of said tube, a second disk positioned against the outer surfaces of said fingers of said second plane of each end of said tube, and staple means securing said disks and said fingers of the respective tube ends together, said staple means comprising a plurality of metal staples passing through the respective disks and fingers, each of said staples of the respective tube ends passing through both a finger of the respective first radial planes and a finger of the respective second radial planes.
3. The filter cartridge set forth in claim 2 wherein the fingers of said first and second radial planes of each tube end alternate in circumferential positioning about said tube.
