with the two layers .rolled together toprovidea substantially solid body, the bodybeing placed in a bag of fabric and restingon a wire-mesh bottom placed in the bottom of the bag.
. and arrangement of several parts, to be hereinafter fully described,l and illustrated in 4the accompanying drawings and specically pointed out fin the appended claims. i
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:-v Fig. 1 is an elevation with parts in vertical section of the device.
Fig. 2 is a transverse sectional 'view through mg. 1a u Fig. 3 is a vertical sectional view through the improved cylinder.
Fig. 4 is a. top plan view of the inner member.
lAs shown in these drawings, the letter A indicates the body of the` illter cartridge which is composed of wiremesh 4I and waste material! or the like; In carrying out the invention, the layer of waste material is placed on the Wire mesh and then the parts are rolled into'a cylindrical body as willbe seen from Figs. 1 and 2, the layers forming spirals. The body is placed in a bag 3 v of fabric and a disk 4Il of wire mesh is-placed in thebottom of the bag before the body is put in place and I prefer'to make the upper end ofthe cartridge of dome shape as shown in Fig. 1 with the upper end of the bag tting snugly this part of the body and suitably fastened at its top as shown in Fig. 1.*
Figs. 3 and 4 show a cylinderfor containing a. cartridge and as shown in these views, thefcylinder comprises an outer member or tank I Il having the cover I I with means, not shown, for providing a tight juncture between the cover and the upper end of the tank and within this tank I0,is a smalleng'aging' portions of the upper part of the tank I so as to space thev tanks apart. i Both tanks have rounded lower ends with their ends -connected together by a perforated tube I4, the'tube having a plug I5 threaded in its lower end. The
perforations of the tube communicatawith the space I6 between the bottoms of the tanks and- .aspring-pressed checkvalve Il normally holdsA the bottom of the inner tank out of communication with the space I6 and theinterior of the This invention 4relates to a iilter cartridge 4for per tank I2 which has lugs I3 `at its upper end forl tank and rests upon the bottom I3, the top of the cartridge being covered by a perforated substantially semi-spherical memberr 22.
Thus the oil or other fluid owing from ythe supply or other container will pass through the nipple 20 and discharge through the port 2l into the bottom of the inner tank and -then pass through the opening I9 and through the cartridge and then through the member 22 and out through the outlet 23, When the pressure below the cartridge becomes excessive, said pressure. will move the `valve `I 'I o its seat so that the oilwill by-pass around the cartridge through the tube I4 and the space I Gand flow outthrough the outlet 23.
Whenffit is desired to remove sediment from the bottom of the tank Ill, the plug I5 can'be removed together with the valve assembly and then the parts can be drained and the sediment will pass through the perforations in the tube Il.
The oil collecting in the space between the twol tanks willact as a cooling medium for the oil passing through the device and as will be seen from Fig. 3, whenthe plug 'I5 is in position, it
covers the lower perforations in the tube I I so.
that the by-passed oil will not disturb the sediment' in the bottom of the outer tank but when the plug I5 is removed, the oil and sediment will drain from the bottom of the outerl tank through all the perforations in the tube I4. I
It is thought from the foregoing description that the 'advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction aind in the combination and arrangement of the several parts, provided that such changes fall appended claims.
I claim: 1. In a. lter device, a cartridge cylinder comwithin' scope of .the
prising an outer tank, an inner tank'spaced from the outer tank, a -discharge -connection at the top of the outertank, 'a ltering cartridge in said inner tank, means for. introducing theiiuid to be iiltered into-the bottom of the inner tank below the cartridge', a perforated tube connecting the bottoms of the two tanks together with the perforations connecting the' interior of the tube with the space between the tanks, and a tank, a ltering cartridge in said inner tank.
means for introducing the ,uid to be filtered irnto thebottom ofthe inner tank below the cart'ridge and means for by-pas'sing the uid be-V tween the tanks when the pressure of the fiuid at the' bottom of the inner tank becomes excessive, such means comprising a. perforated tube in communication with the bottom of the inner tank and' the perforations placing the tube' -in communication with the space between the tanks, an adjustable spring-pressed valve normally closingy communication between the tube and the 5 bottom` of the inner tank.
3; In a filter device, a cartridge cylinder comprisingan outer tank, an inner tank spaced from the outer tank, a discharge connectionat the top of the outer tank, a filtering cartridge in -10 said inner tank, means for introducing the iiuid tobe filtered into the bottom of the inner tank below 4the cartridge, a perforated tube connected,
with the-bottoms of the two tanks with its upper end in communication with the 'bottom of the l5 inner tank, and the perforationsv connecting vthe interior of the tube with the space between the tanks, av'alve for normally closing communica' f tion betWeen..the.- tube andthe inner' tank and) opening'when excessive pressure occurs in the 20 bottom of the' inner-tank, some of the perforations in the tube being arranged 'in the upper portion thereof and some in the lower portion thereof anda plug closing the lower end of thc tube and the lower perforations, said plug being 254 removed when thel tanks are. to be drained.
