This invention relates to oil filters and has particular reference tol an oil filter of the spiral bag type andthe'mounting thereof in its container.
The oil filter container is composed of separable parts in order that access may be had to the filtering material to remove and replace it. The filtering element of the invention is mounted inthe container as a unit and comprises a spiral wire over which a filter Abag is placed. A wire or cord is wound between the spiral of the wire and entwines or pulls the filter bag into the spirals to thereby give a spiral-formed filtering unit. End plates are at each end of the filter unit, one of the plates being rigidly secured to the filter bag by means of an outlet nipple. The other end plate is freely placed on the bag and is joined to the first end plate by means 2 of a plurality of straps having flanges facing outwardly of the filter. Both ends of the straps are hooked into openings in the end platesand adiacent one of the plates. preferablv tbe plate rigidly secured to the filter bag. the flanges on the straps are cut away in order to permit of a limited movement loetween the straps and end plate. The purpose of this movement is to utilize the spring tension to hold the nipple tightly on its seat as.y 3 well as to keep the bag assembly unit tightly in its shell. the movement being limited so as to thereby prevent the nipple from coming out of its seat or socket during shipping in transit or while applied to a vehicle. 0n the drawings:
Figure 1 is a sectional view through the filter showing portions of the filter bag in section and in elevation.
' Figure 2 is a, side elevation of the filter container. l f Figure3 isa plan view of the structure of Figure 2 on a reduced scale. 1
Figure 4 is a side view of the structure of Figure 2 on a reduced scale.
Figure 5 is a view of the spiral wire filter bag and end plate showing a portionof the bag entwined in the spiral wire and the remaining or.lower portion free.
Figure 6 is a view of the filter bag per se.
Referring to the drawings, the numeral 2 indicates the container as a whole. The container comprises the upper separable portion 4 and the lower portion 6, each having a fiange 8 and 10 at their place of meeting. The fiange 8 is also upwardly turned as indicated at 12 and a gasket 14 is received between the iianges to make an oil tight connection. A ring 16 is secured to the upper section 4 immediately adjacent the fiange l0 and is provided with a plurality of openings to receive the bolts 18. The ring 16 preferably comprises the two right angularly bent flange portions 20 and 22, the flange portion 20 striking against the fiange 10 of the portion 4 of the container.
The lower portion 6 of the container 2'is also provided with a ring 19 comprising the flange portions 20 and 22, the portion 20 of which strikes against and supports the iian'e 8 of the container. The rlng 16 is ,pre erably loosely mounted on the container ut may be rigidly mounted if desired and is provided with openings adapted to receive the bolts 18. The openlngs in the rings 16 and 19 of course conform to each other. Nuts 24 are applied to the bolts to pull the two halves on to each other and to tighten the rin s 16 and 19 and flanges 8 and 10 on the gas et 14. B unscrewing the lscrews 24, the upper hal 4 may be removed from' the lower half 6. I
The lower ring 19 is provided with an integral bracket portion 26 having the openings 28 for the reception of bolts to secure the filter to a suitable mounting. The lower half 6 is also provided with the ring clamp yso 30 having its ends secured together by 'means'A i o the bolt and nut 32.r Theends 34 are provided with the openings 36 to serve as an additional means to secure the filter in place.
- The clamp ring 30 may, if desired, be entirely omitted.
The bottom 37 of the lower portion 6 of the container is provided with the fitting or socket 38 adapted to receive the screw-threadthe bottom of the container and is screwthreaded for the purpose of receiving the inlet plipe to the filter.
A t ird itting or socket member 44 is rigidly mounted in the container bottom and has the screw-threaded bore or opening 46 to which the outlet pipe is adapted to be attached. The inner portion of the socket 44v is rounded as at 48 and adapted to receive the corresponding rounded portion 50 of the nipple` 52 which is provided with a bore 54 cmmunicating with the outlet pipe of the ter.
The ltering unit of the invention is indicated as a whole at 56and is adapted to be inserted and removed as a unit from the container 2. The filtering unit comprisesi the relatively heavy resilient spiral wire 58 over which there is drawn the filter bag 60 asis best shown in Figures 1 and 5. The ilter bag comprises a relatively long substantially 'cylindrical bag of preferably cotton and preferably has its'nap facing outwardly.. An
A second end plate 68 is placed over the opposite end of the spiral wire 58 but is not secured to the bag or spiral. If desired, a cloth disc may be-placed between both of the end plates and the filter bag 60.
Both end plates 62 and 68 are provided with openings 70 adapted to receive the hooked ends 72 of straps 74 whichhave the lateral flanges indicated at 76. Adjacent the upper plate 68 the flanges 76 preferably are arranged very close to the plate to permit very little if any movement. At the lower end, the flanges 76 are cut away as shown at 78, the purpose of which is t'o allow a limited amount of movement of the plates toward and from each other. The purpose of this limited movement is to utilize the tension of the spring or spiral wire 58 to hold the nipple 52 tightly on its seat 48 in the socket 44 as well as to keep the bag assembly unit 56 tightly in its shell or container 2 and by the limited movement to prevent the nipple 52 from coming out of the seat 48 during shipping or as a result of rattling when the filter is applied, asfor instance to an automotive vehicle.
By referring to Figure 6, it will be noted that the ilter` bag 60 comprises a long strip of filtering material folded upon itself as at 80 and sewn as at 82 entirely along one side. The end 84 is also sewed and a seam is formed half-way down the other side-as shown at 86. With the bag in this form, the end plate 68 and nipple 58 are applied and the three rigidly secured together. The spring or splral wire 58 is then inserted at the open portion 88 and the bag is sewed along the open portion 88. The wire or spring 64 is then applied in the opening 66 and wound between the spirals of the spring 58 to draw the bag between the spirals as is shown at the upper portion of Figure 5 and in Figure 1. The end plate 68 is then applied and the straps 7,4 secured in place. The unit 56 is then complete and may be inserted in the container 2 so that the nippleJ 52 will fit in the seat 48. The upper portion 4 of the container is then applied and the bolts 18 and nuts 24 secured in place to rigidly'hold the lter in the container.
In operation the oil enters at the inlet l42 and passes between the spirals of the filtering material. The cloth will retain the impurities while the -filtered oil will pass through the interior of the filter and out through the nipple 52 and socket 44 to the outlet pipe. When it is desired to clean the filter, the cover 4 is removed and the unit 56 withdrawn as a whole. It may be cleaned in any suitable way and then replaced or a new filter unit may be applied. i
If desired, the oil may be caused to enter the filter-at the socket 44 and pass outwardly through the cloth and leave at the socket 42. In the case of this reversed ow, the sludge or impurities will of course be collected on the inside instead of the outside of the bag.
I claim: 1
