Nov. 12, 1940. T. E. ALDHAM CARTRIDGE FOR OIL FILTERS Filed Jan. Z7, 1938 INVENTOR. YZ0/a5 ima/ff ATTORNEYS.

Patented Nov. 12, 1940 charmes ron on. mrsas Thomas E. Aldhani, Providence, B. L assigner to Fleming Manufacturing tion f Rhode 'Island Appuesnon'rmusr'y 21.19311, No. 187,110

a claim. (ci. 21o- 1an This invention relates to an oil lter of thev type used in connection with engines which depend for their functioning upon a continual circulation of lubricant; and this invention1 has for one of its objects the provision of an arrangementv whereby should the iiltering medium become clogged a supply of. lubricant would still be circulated to lubricate parts of the engine.

Another object of the invention is the provision of means to by-pass the filtering medium should the pressure required for passage of the oil through the filtering medium increase to such anf extent as to endanger the supply of lubricant to the moving parts of the engine.

Another object of the invention is the provision of a by-pass means in the cartridge which is'V removed and replenished so as to assure a fresh by-pass means each time the cartridge ls changed. and prevent failure o'f the by-pass closure to direct the oil as desired by reason of -i'atigue of resilient means usually used for causing.

such closure.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

l is a sectional view of a filter casing with so cartridge therein illustrating my improved byv pass container within the cartridge:

Flg.,2 is a sectional view on line 2-2 of Fig. l. It is considered desirable to provide 4for a bypass of a nlter in the event thecartrldge becomes 35 so clogged that the oil will not readily pass therethrough. Such a by-pass is sometimes provided in the mounting for the iilter casing or in the casing in such a manner that it` remains continually in such location throughout the life of o the mounting or casing. Such a bypass usually has some sort of a springer resilient means for operating it. I'his spring through frequent operation often becomes `fatigued and the valve means for controlling the by-passis permitted to u open and the functioning of the niter medium does n'ot Play the part which it is intended to perform. Accordingly, I have'chosen to locate the by-pass in the cartridge vwhich is intended to be removed from time to time and which 5g serves to protect the lubricating system should thecartrldgc become'clogged or the pressure be increased while at the sametinie as the cartridge is removed from time to time a fresh resilient closure valve'is supplied each time a new cari6 trldge is put inplace and the fatiguingand failure of the closure is eliminated; and thefollowing is a more detailed' description of the present embodiment of this invention, illustrating they preferred means by which these advantageous results may be accomplished:

'With reference to the drawing, Il designates a casing of generally cylindrical form having a bulging bottom wall il provided with a discharge conduit I2. 'The' side wall of the casing is bulged outwardly as at Il provided with an inlet conduit 10 Il. A cover I5 is located on the outwardly flanged portion I2 of the side wall which is bolted in place by suitable'fastening means I1. Apacking I8 exists between the cover and the ilange for sealing the cover in'positio'n. 1

A cartridge designated generally I! is also of cylindrical formation havinga .bottom wall,20 and a top wall 2| both of which.'y are iirmly secured in position on the cylindrical'side wall while there is a central opening 22 formed by tube 20 23 extending axially through the cylinder I9. Filter material 2l is positioned within the cartridge. A resilient spring or handle 25 which engages the cover serves to force the cartridge downwardly on the packing 28 to form a seal 25 between the inlet and outlet conduits.

'I'he top wall 2l in the portion above the centralopening 22 is provided with anopening 21 which receives a housing 28 comprising an upper wall 2! having a hole 3l therein which is sealed 30 by a ball 3| urged into engagement with the edges of the opening by a-sprlng 22 engaging the in-turned lips 22.0f the side walls 24 and leaving anv opening 2l between them. Oil which enters through the conduit Il passes through the 85 perforations 28 in the cylindrical wall of the cartridge Il through the filter mediumil and outV through the perforations 31 in the tube 23. The entire .volume of the chambers 28 and 2l at the sides and top of the cartridge are full oi' 4o oil and should the pressure in this volume of oil increase beyondvthe pre-determined calculated pressure of the spring 32 whichl forces the valvev 3l to closed position, the valve would then be forced-inwardly against the vspring and the oil s would pass through hole 3l` through-the spring chamber and out through the space` 3l throughthe central opening v22 and out the ydischarge conduitv l2, thus, by-p'assing the filter medium 24. If, however. thepressure doesnot exist beyond a predetermined calculated amount, the oil will then pass through the nlter medium 24 down to the tube 22 and out through the conduit I2. l

us, a lay-pass is provided which protects the c ting vsupply .of lubricant to the engine ena it n 'se llocated and ended by sa cartridge um it-wm be removed when un .eem-loge is re- IBBSOD. bf fatigue.

moved or changed that a fresh one be substituted therefor, thus replacing the resilient portion of the by-pass before any injury may come to it by The foregoing description is directed solely towards the construction illustrated, butvI desire it to be understood `that l'I reserve the privilege o f resorting' to all the mechanical changes to which the device is susceptible. the invention being defined and limited only bythe terms of the appended claims.

I claim: y 1. A filtercartridge comprising a package of filtering material, a perforated wall surrounding and permanently enclosing said filtering mate,-

rial andvhaving annular imperforate end walls over the ends of said nltering material, a central tubular discharge conduit secured at its ends to saidend walls andhaving perforations and ex-v tending through the filtering material for outlet of the filtrate after its passage through the filtering material, a by-pass conduit within said discharge conduit and supported at the upper end of the'cartridge to afford a passage of the i'iltered liquid from the direction of the upper end wail of the cartridge when excessive pressure or clogging of theilitering material occurs, said by-pass conduit comprising a housing having a side wall I. spaced from the perforated portion of said distween said upper and lower walls of said housing, to normally urge said ball into a closed fluid charge conduit, upper and lower end walls in said housing each with a central opening therein, a ball valve for engaging the edges of the opening in said upper end wall, and a spring acting befor egress of the nitrate after its passage through the filtering material, a by-pass conduit within said tube and carried by the upper end wall of the cartridge to afford a passage of the filtered liquid from the direction of the vupper endwall of the cartridge whenA excessive pressure or clogging of comprising a housing `having a side wallspaced from the perforated part of said discharge con duit, upper and lower end walls in said housing each-with a central opening therein, a ball valve "normally engaging theedges of the opening in `,said upper end -wali of the housing for controlwalls extending through the filtering materiall for egresa'of` the filtrate after its passage through the filtering material, `a by-pass conduit'within vthe ltering material occurs, said by-pass conduit said tube and carried by the upper end wall of the cartridge to afford a passage of the filtered liquid from the direction of the upper end wall of the cartridge when excessive pressure orclogging of the filtering material occurs, said by-pass conduit comprising a housing having a side wall concentric with and spaced from the perforated part oi' said tube and extending inwardly thereof from the upper end wall of the cartridge, upper and lower end walls in said housing each with 'a central opening, said upper end wall of said housing being secured to the-annular upper end wall of the cartridge and having an opening the edges of which form a seat for a ball valve, a ball valve the edges of said opening in said upper end wall, and a spring acting between said upper and lower walls of said housing tc normally urge saidball into a closed position i THOMAS E.
