OIL-FILTER.

SPECIFICATION forming part of Letters Patent No. 7 32,6 59, dated June 30, 1903.

Application filed October 2, 1902. Serial No. 125.705. (No model.) Y

To all whom t may concern.:

Be it known that l, BEnXToN L. SCOTT, a citizen of the United States', residing at "Washington, in the District of Columbia, have invented new and useful Improvements in Oil- Filters, of which the following is a specification.

My invention relates to certain new and usevful improvements in oil-filters, and has for its object to provide a filter which shall be sim-` ple in construction and operation, which may be readily taken apart for the purpose of cleaning, and in the use of which the oil will be rapidly and, thoroughly cleansed from impurities.

With these objects in view the invention resides in the novel construction, combination,

and arrangement of parts hereinafter described, and particularly pointed out in the claim. In order that my invention may be clearly understood, I have illustrated the same in the accompanying drawing, in which the figure is a central vertical section of a iilter constructed according to my invention.

Referring to the drawing, 1 indicates the outer containing-tank having, as usual, drawo cocks 2 and 2EL and a gage 3. Within the tank 1 is a receptacle 4, having a downwardlycurved upper-edge portion 5, by means of which it is supported from the upper edge of the tank l. The receptacle 4 tapers slightly from top to bottom and has about the depth relative to the tank 1, as shown. The bottom of this receptacle is open except for a narrow inwardlyextending annular flange 6. Upon this liange is supported a second receptacle, 7, which for the purpose is provided at its upper edge With a similar outward-extending flange'S. Said receptacle 7 also tapers from top tobottom, is of slightly less depth than the receptacle 4, and is provided in the bottom with an outlet 9, through which the oil may ilow down into the tank l, whence it is Withdrawn through the draw-off cock 2. Each of the receptacles 4 7 is provided on its inner side near the top With handles `10 11, respectively, and at a suitable point above the bottom the receptacle 7 is provided with cleats 12. Four or more of these cleats may be employed. These cleats are for support- Vtank l.

ing a disk 14 of open-work fabric, such as woven wire, which is removably seated upon` said cleats. A similar disk 15 is removably seated upon the flange 8 ofthe vessel 7. Each of said disks 14 15 is adapted to support a sack of bone-black 16 17, which sacks are of course circular in shape and of a size to fit snugly within the respective receptacles 4 7. In the upper receptacle "4 at a suitable distance above the sack of bone-black 16 is located a circular plate 13, havingperforations 18, said plate being supported upon cleats 19, upon which it is removably seated, and having a handle 20, by which it may be lifted out of the receptacle 4. The tank 1 is provided with a cover 21, having a handle 22.

In operation oil ,is poured into the receptacle 4 upon the plate .'13, which being perforated throughout acts Aas a baffle-plate to distribute the oil and cause it to fall over the entire surface of the upper sack 16 of boneblack. The oil percolates through this filtering medium and through` the disk 15 and falls upon the lower sack 17 of boneblack. Percolating through the `bone-black in this latter and through the disk 14 it passes out through the outlet 9 and falls to` the bottom of the In passing through the two sacks of bone-black the oil will be thoroughly cleansed from all impurities and when drawn from the tank 1 may at once be used again.

This filter is intended more especially for use in po wer-houses and similar places where hundreds of gallons of oil are used daily for lubricating the machinery, the oil after use being collected and passed through the filter to remove from the oil all grit and impuri` ties, so that the same oil may be used over and over again. The salient feature of the invention, however, is the facility it affords for the ready removal and replacing of the therein,no mechanism-such as bolts, screws, or the likebeing required for securing any of the parts in position. As Will be apparent from the drawing Without further. detailed liilteringt-receptacles and the parts supported IOO boiled or otherwise treated to remove grease and impurities therefrom which have been absorbed or Collected by the bone-black in the filtering operation.

Ofeourse I do not limit the invention to the use of bone-black as a filtering medium, as any other suitable substance may be employed in lieu thereof.

Having thus fully described my invention, what I claim as new. is-

In an oil-filter, in combination with an outer tank, a receptacle having an upper curved edge portion in engagement With the upper edge of said tank and having an open bottom provided With an inwardly-extending flange, a second receptacle having a flanged upper edge and supported therebyfrom the bottom BRAXTON L. SCOTT.
