nppiicatin' ined January 2s, 1925. serial No, 5,232;

This invention relates to oilstrainers and especially to a duplex formv thereof.

The object of the present inventionv is to generally improve and simplify the construction and operation of oil strainers; to providewa casingV having three cylinders formed therein, two for thek reception of straners and one for the reception of a valve mechanism;V to providemeans whereby the strainers and valveslmay be readily and quickly removed'for cleaning, inspection, repair, etc.; to provide a valve mechanism which is adapted to direct the oil flowrthrough one strainer or the other, thereremoval and cleaning, while the other is in operation; -to Yprovide valvesV which will automatically compensate for Wear; to prol vide means whichwill visibly indicate the position of the valve mechanism, or, in other words, the strainer throughrwhich the oil is passingg. and further, to provide an arrangement of strainers, valves,.etc., which permits compact assembly and ready installation wherever required.

One forml which my invention may assume is exemplified in the following description and illustrated in ythe accompanying drawings, in which t 30 F ig. lis a planview of theduplex strainer and the valve mechanism' employed in con- Fig. 2 isa front vview. ofthe same. Y, v

This lcasing has a cylinder chamber formed therein as Vat 3, this chamber being provided for the reception of avalve mechanism hereinafter to lbe described, whileV the. cylinders B and C are provided for'the reception of strainers through which theoil is passed'v for the purpose of removing sand or otherimpurities. lThe oil to bestrained enters Vtlie cylinder by leaving one strainer freeat all timesfor line III- III of vFigure 1 ;onlyone .valve Sthrough'an inlet port generally indicated l at 4. yIt is then directed by the valvemech- NT;.orricaj Assieivon To conn coiviriinv.orv 'l' anisni through one'or another'of a pair of in the casing A.

rlhis isaccomplished in the'following man- 5*"7 ner: v

By-referring to 'F ig. '3 it will be noted" that the valve cylinder 3 is provided with upperV and lower removable heads such as shown at' I() and 11 respectively. Extending' through the upper Vhead is al valve'stem orl shaft 12. This shaft is supported-by the 4lowerhead and is journalled therein as attl. Secured on the upper end of the shaft is avvalvefh'ubV 14 and similarly 'secured on the lower end of the shaft is a valve hub 15. These hubs are provided withprojecting pins 16 and each set of pins serves as` afsupportfor a segmental', shaped valve, the, upper valve being lindicated at 17 and the lowerl valve f at 18. These valves are maintained incontactA with Lthe Vinner surface of; :the valve cylinder, as springsy 19 are interposedv between thev valvesand the valve hubs."vv In other words, a pair ofjoating valves zis employed so thatY anywearfwhich'may take place' will be automatically compensated' for.

The valves-are mounted in Adirect valig'iiment, one above the other, and they thusv servethe function ofV closingtheupper and f f lower ports 6 when they:assume'thel position shown i in; F ig. 1 and that` of 'closing the upper and lower' ports '5" when the valve` is turned-'to thzedotted line position,"also Vshown irl-Fig. 1. 1 i" of cast-iron or similar material, which is To `prevent short-circuiting ofthe oil while passing through the valve cylinder and V theljstrainer cylinders, or, "in other Vis indicated at vv20 andis'f-secured `against vertical movement by being vplaced betweenV the valve hubs v14 and 15.
