2 Claims. 210-62) ,y

This invention relates to oil filters, and in particular to oil lters of the type used in contin'uous, pressure-lubricating systems of internal combustion engines; and has for one of itsobjects the mounting of an oil lter of the above class in such a manner that it is capable of being conveniently moved bodily into a position diiierent from its normal operating position for facilitating either the insertion or the Withdrawal of the filter cartridge unit from the casing when the lter is installed in a restricted location which renders such removal of the lter cartridge impossible.

Another object'of the invention is to provide a two part filter mounting which may be quickly separated and connected whereby movement of the entire lter assembly bodily into a position well removed from its normal operating position for effecting replacement or inspection of theA filter cartridge by separation of the mounting device may be accomplished but without the necessity for disconnecting the piping or conduits connecting the filter to the iiuid system of the internal combustion engine.

Another object of the invention is the provision of a detachable filter mounting device of the above character in which the entire weight of the filter assembly will be borne by interengaging means carried by the separable and independent parts of the mounting device wherein the auxiliary securing means for maintaining the separate and independent parts of the mounting device secured together will be entirely free of any applied pressure incident to the weight of the filter. Y Y

Another object of the invention is the provision of a two-part mounting, and coupling means which are permanently carried by the mounting for positively securing the parts of the mounting into abuttingl relationship and cannot bc accidentally removed and 10st.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and

The ordinary filter mountings hitherto used for `installing the large size oil filters of the type required inthe lubricating circulating systems ofthe internal combustion engines of trucks, busses and tractors, do not meet all requirements met with in the eld, as it is often necessary,

` 'especially in motor truck or bus'designs of" the .cab over engine type, to install and operate such oil lters in locations where there is practically no overhead clearance-orspace between the top of the filterA and the adjacent parts of the engine chassis or body of the vehicle, in which instance, there is no room to permit the withdrawal of the entire lter cartridge unit for inspection and/or replacement when a lter is mounted in such conned locations; and in 0rder to overcome such diiliculties I have provided a mounting device for supporting and sustaining the filter unit in proper operating position parts are positioned face to face in abutting relation; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawings I designates in Figs. 1 and 7 the casing of an oil filter oi this class which is of generally cylindrical shape and mounted in an upright position upon a mounting device embodying the present invention. The

slid through a slot I0 connecting the larger lop 39 with the smaller loop 4| brings the head 31 of the stud into overlying relation with the edges casing I0 is provided with the usual cover I2, l

ltering element (not shown) and inlet opening I3 and outlet opening (not shown) to which flexible conduits are attached as indicated by the reference characters Il and M', for connecting the filter into the lubricating system oi an internal combustion engine. The mounting device consists of a front plate member I5 and a rear plate member IB of approximately the same size and shape made of iron or steel, or some other suitable metal. The rear plate member l'has at its upper edge a rearwardly extending flange I8 which beingformed with a hole I! of suitable size for the reception of a bolt provides for mounting theplate I6 upon a ixed support, such as the block of an internal combustion engine or some part of the frame or the transmission casing of a motor vehicle. The lter casing I3 is detachably mounted upon the iront plate member I5 by means of a pair oi'

clamps

23 and 2|, each of which consist of a plurality of arcuate straps or

bands

22 and 23 respectively (see Fig. 3) the curvature of which conforms substantially to the exterior curvature of the casing and to embrace the same. The

straps

22 and 23 are held in tightly clamped engagement with the sides of the casing by bolts 25 which pass through suitable holes in the flanges 23 formed on the free forwardly extending ends of the

straps

22 and 23 respectively. The

straps

22 and 23 are of identical construction, and they are pivotally mounted at their rearwardly extending ends by means of lugs 21 struclr out of the stock o such ends of the straps, as shown in Fig. 4. The lugs 21 of each set of

straps

22 and 23 are each disposed within a U-shaped channel 2B of bracket 30 by sidewise insertion through the elongated slots 3i formed in the corners of the channel 28.

Bolts 33 passing through suitable slots 33 in the straight anges 35 of the bracket 33 serve to hold the bracket xed to the front plate I5. In order to couple the plate members I2 and I6 together so as to provide a rigid mounting for the lter during its normal operation I have provided on the front face of the rear plate member I5 a plurality of projecting studs 36 each having an enlarged head 31 and adapted to be inserted into and project through the recesses 38 formed in the front plate member I5. The recesses 38 as shown in Fig. 5 resembles the figure 8 in which one loop 33 of the recess is of a size large enough to permit the free passage of the head 31 of the stud 36 the shank of which after being of the smaller loop 4| which serve as abutments to prevent passage of the head 31 of the stud through the opening of the loop 4I when the plates I5 and I6 are in registry and in abutting relation for holding the iilter in its proper operating position during use.

A suitable locking device may be employed for maintaining the plates I5 and I6 in their abutting relation, such as, for example, a bolt 43 one end of which is integrally secured to the rear plate member I6 with the other end of the bolt projecting through an elongated slot M inthe front plate I5, the free projecting end of the bolt being in an easily accessible position for ready tightening or loosening of a nut 45 carried on such projecting end portion of the bolt and serving to clamp the plates I2 and I3 together.

In Figs. 8 to l0 inclusive, I have illustrated a modiiied form of the invention comprising a pair of separate and independent plates and 5I. the rear plate 50 being formed with an upwardly inclined transversely extending lip 52 at the lower edge of the plate for engagement with the lower edge 53 of the front plate 5I when the latter is placed face to face in abutting engagement with the plate 50 as shown in Fig. 10. A lip 55 extending upwardly, rearwardly and thence downwardly from the top edge of the front plate 5I and partially across the same is provided for engaging the top edges 56 of the rear plate 50 V when the plates 50 and 5I are in their assembled and abutting relation. The front plate 5I is also provided with a plurality of internally screwthreaded holes 51 for detachably mounting the brackets 58 and which pivotally carry the separable clamping straps or bands 5S for positively engaging and securing the casing to the front plate 5I. A bolt 60 fixed to the plate 5U and projecting through a slot 6I in the front plate 5I carries a nut 62 for securing the plates 50 and 5I in assembled position as shown in Fig. l0.

In Figs. ll, l2, and 13 there is shown another modified form of the invention in which the plates 10 and 1I are each provided with a plurality of lugs 12 and 13 respectively which are struck out of the stock of the respective plates and have interitting engagement one with the other when the plates 10 and 1I are placed face to face in inverted position and into an abutting relationship, as shown in Fig. 13 lor supporting a filter casing, 15.

A bolt 1E integrally secured to the plate 10 passes through an elongated slot l1 formed in the plate 1l, and the projecting end of the bolt carries a suitable nut (not shown) for securing the plates 10 and 1I in their assembled relationship in which position the entire weight of the filter assembly is carried solely by the lugs 12 and 13 and is not imposed upon the stud 16 which acts solely as a locking device for maintaining the plates 10 and 1I in proper assembly.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1.
