sAsoLnN'E on OIL ,rrmrin.

Specification of Letters Patent 7 Application filed May 4, 1909. Serial No. 493,930,.

lene on its way from the tank to the engine, although it is also intended to be employed for filtering oil and other fluids.

It has been contrived with especial reference to trapping water and dirt, without contact of the same withthe filter-screen, so as thereby to obviate the clogging of the latter. Also, with reference to enabling it to be used in either a vertical position or a hori zontal one, and to be combined with the pipe-connections in a variety of ways, according to the arrangement of such pipeconnections. Also, with reference to enabling the filter-screen to be removed or replaced conveniently and (prickly.

The drawings show an embodiment ofthe invention, and represent difierent positions in which it may be used in practice.

Figure 1 thereof is a v1ew ofthe said embodiment in elevation as employed in an upright position. Fig. '2 is a view of the same in vertical section, except the pet-cock, Fig. 3 is a view in horizontal section in the 3 plane of line 3, 3, in each of'Figs. 1 and 2.

, Fig. 4 is a view of the said embodiment in vertical section as employed in a horizontal position. Fig. 5 is a detail view in planof one of the gauze disks or" the filter-screen.

The filter comprises, essentially, the body or barrel 1, the cap 2, and the filtenscreen 3.

. At 4 is a pet-cock which is applied to the;

body or barrel; a v

The body or barrel 1 usually is made with provision for attachment to some part or support so as to keep the filter in the desired place, or support it. In this instance it is formed with a lug 1 through which is made a hole 1* for the reception of the stem ofan attaching bolt, or the like.

Body or barrel 1 has a central chamber, open at the end where the cap 2 is applied, and two small openings communicating through its shell with the said chambeii, one

thereof, 1, being located at oneside, 'and" the other, 1 at the end opposite the large.

opening for the cap. These openings 1, 1

are circular and correspond in diameter with the threaded shank of the pet-cock 4 and the threaded end of a pipe-connection leading to the filter. The walls of such open-' 'ings are internally threaded for engagement with the said threaded portions. Either of the said openings may serve as the inlet for the gasolene, or other fluid to-be filtered, and will have anend of 'the supplypipe (not shown) screwed into the same. The pet-cock t will be applied to the other, by screwing its threaded shank in. place.

The cap 2.is in screw thrcaded connection with the open end-.of the body or barrel. In the illustrated construction it iseXternally threaded at its peri hery,-and' screws into the said-open end, wh threaded. It is-formed with an internal ich is mternally' chamber forming a reservoir for filtered gasolene (or other-fluid), and carries by its inner portion, the filter-screen 3, the said inner portion being internally threaded for en agement with the externallythreaded body of the said screen. The outer. portion of the ca is formed with an outlet 2",

through w ich the filtered gasolene or other.

fluid flows from the said reservoir. The wall of the outlet is internally threaded to receive the externally-threaded end of a pipe-connection (not shown) leading from the filter. I

" The filter-screen 3 comprises a cylindrical body-portion orshell 3*, and disks of gauze 3", 3*, covering the opposite ends'of the cen? tral opening of such shell Each of the said disks is fastenedrto a ring or collar 3 which fits-within the corresponding end-portion of: the shell. The latter is internally threaded adjacent its respective crisis and the rings oincollars 3, 3, are correspondingly-threa ed externally and screwed ,into the shell untilthey rest against the shoulders 3, 3.' To

facilitate turning the rings and disks, each ring has a cross-pin 3*, which extends diametrically and may be taken hold of with ones fingers or a pair of pliers. The rings may readily be applied to the body-portion or shell 3*;01' either or both of them may be disconnected therefrom. The periphery of the body-portion or shell 3 is exteriorly threadd and screws into the inner portion ."l he eby the filter-screen is at- K i hgcaliisoas to be supported, there When the cap is applied'to the barrel the Screen is placed 1n working position. When the cap is removed from the barrel it takes the filter-screen with it. The filterscreen is readily applied to and detached from the cap. The filter-screen is supported by the-cap within the body or barrel in a position intermediate the opening 1 and the outlet 2, and with more or less space interveningbetween the inner surface of the body or barrel and the central opening of the filter-screen.

The space within the body or barrel constitutes a receiving chamber for the gasolene or other fluid.

When the filter occupies the vertical posi-' tion in which it is shown in Figs. 1 and 2,

' the opening 1 being used as the inlet, and

I the pet-cock 4 being fitted to the opening 1,

the filter-screen is entirely above the said inlet. Fluid entering by the inlet does not flow directly toward the filter-screen, but across below' the same. Consequently. impurities, such for instance as Water and dirt, have a 'chance to settle'to the bottom'of the receiving-chamber, without being carried against the filter-screen so as to choke its interstices. They may be drawn oil, as usual, through the pet-cock 4. O

When the filter occupies the horizontal position in which it, ,is sh own in Fig. 4, it may be disposed with opening, l at ,the under side, as in such figure the said opening having the pet-cock applied thereto. In this case, opening 1 serves as the inlet for the gasolene. .The water and dirtare afforded an opportunity to settle down to the lower side of the receiving; chamber without being carried into contact with the gauze of the filter-screen. Whenthe filter is arranged horizontally as in Fig. 4, the distance be tween the bottom surface of the receiving chamber of the body or barrel and the lower portion of the centralzopening of the filter- -screen is sufficient to allow a considerable accumulation of Water and dirt below the bot- \Vhen the filter is used for gasolene, the

gauze disks alone are required, usually. When used for oil or other liquids a suitable packing may be placed between the two disks.

What is claimed as the invention is 2- 1. A filter of the class described comprising a hollow body open at one end and provided with a threaded hole at the opposite end and on one side of equal diameters, a cap containing a chamber adapted to screw into the open end of said body and provided with an outlet opening, and axfiange at its inner end, and a filter screen comprising an exteriorly threaded sleeve adapted to be removably screwed into the threaded flange of said cap, removable filtering material within said ring held in place by detachable collars.

2. A filter of the class described comprising a hollow body open at one end and having a threaded hole through the opposite end and one side and-of equal diameters with their axes at a right angle to each other, said holes adapted to interchangeably receive a supplypipe and a pet-cock, a chambered cap adapted to screw into said body and having a threaded hole at its outer end and an interiorly threaded flange at its inner end, and a removable filter screen comprising a sleeve screwed into said cap fi age, and filter material within said sleev retained in position by perforated disks and threaded collars in each end of the sleeve, said filter adapted to operate in either a vertical or a horizontal position by changing thel positions of the inlet pipe and the petcocr.
