UNITED STATES PATENT OFFICE.

GEORGE SAMUEL HALE, or TEKOA, wasmnc'ronf GASOLENE-STRAINER.

Application filed December 13, 1916.

To 071 17. 7107)? it may hone/ ra Be it known that l, (ii-zones SAAH'ICL l'lALE, a citizen ot' the l'nited States of America, and a resident of 'lekoa. county of 'hitn'ian. State of \Vashiugton. have invented certain new and useful improvements in (iasolene- Strainers, of which the following is a tall and clear specification.

The object of this invention is to provide a simple gasolene strainer for attachment especially to those gasolene engines which are employed on motor vehicles. launches ctc. and the invention consists of certain novel featnres of construction hereinafter described and claii'ned.

in, the drawing, the figure represents a vertical sectional view of a preferred toriu of the device.

i In this drawing, a designates the inlet pipe of the device which is screwed into a nipple 5 formed on the upper or cap member c of the chamber. The inlet pipe extends down into the-chamber and is provided with a downwardly-facing shoulder (Z near its inner end. A 'gasolene outlet pipe 0 is connected with a central chamber f in the upper part of the cap 0, this chamber surrounding the reducer extension g of the inlet pipe.

An annular downwardlydaelng shoulder h is formed on the interior of the rap 0 in l the same horizontal plane with the aforesaid shoulder d, and clamped up against these shoulders d and h is a felt strainer disk t, the clampin means in the present instance being ac 'Tindrical extension of sediment cup which is screwed up into the cap 0 so that its annular edges are made to engage the oposit-e marginal edge of said disk. The

. ower end of this cup is tapered and round ed downwardly so as to collect sediment 1n its bottom at a distance from the inlet and strainer disk. Foreign substances that are collected. in this cup may be discharged through a discharge Opening in the bottom of the cup, this opening being controlled by a suitable valved pipe connected to the cup.

The gasolene enters the strainer through thepipe (1 whose discharge mouth is [lush with the undersideof the strainer. and then passes up through the porous disk 1', into a chamber formed between the same and the and thence into the annular chamber 7, whence it passes to the carburetor of the engine. All foreign substances including sand, lirt and water, settle by gravity to the bottom of cup 7', the solid Specification of Letters Patent.

foreign matters being strained out 01'' the e asolene by the strainer disk.

It has been l'ouucl to be importantto end the inlet pipe [lush with the underside of the st ra-iuer disk. owing to the fact, learned from practical tests. that it the gasolene is supplied to the chamber at a point the slightest distaneebelow the underside of the disk, air will be trapped in a thin tihn between the felt disk and-the month of the inlet and will stop the How of grasolene through the filter. 'lhereiori: by ending: the inlet flush with the undershle. air can escape back through the inlet until the underside of the disk islhis serious objection applies to llnndrel. gg'ravitv feeding devices.

it will be observml that the. inlet and outlet pipes may be arranged differently with out departing from the spirit of my invention. It will be ohservedthat a feature of importance in my device lies in V the strainer disk faces downwardly, and that it has no meshes. such as wire gauze presents,

. to eatch'and hold foreign solid substances, so

gasolene will be collected in the bottom of.

the cup and that it will not pass over through the disk with the gasolene unless the cup is tilled up to the lower face of the It will be understood, of

the fact that,

of sediment and water from time to time by merely opening the valve intbe (kit thereof. it is important. also that a felt strainer be used in my device. as I have found inpractwo that a. wlre strainer w1ll entangle andhold the 't'oreign matters and thus clog the meshes; and it is further importantthat this filterning disk shall be. readily removable froni the apparatus in orderto occasionally clean it of the finer foreign particles that eventually, work into it. ln order-to make thisdisk removable readily. I utilize the upwardly extending annular flange on the cup 7' to clamp its edge against the shoulders h formed on the wall 0 and also against the downwardly facing shoulder d on the central supply ipe. With this manner of fastening the'disli it is unnecessary to employ a fas- .tening means at the center thereof, since the clamping action of the edge of the disk will be s'uflicient to hold against shoulder d,

it u and it will be observed that to remove the v disk it is simply necessary to unscrew the on e nature and scope of the invention haw ing been thus indicated and its preferred embodiment havin been specifically described, what is claimed as new is:

A device of the class set forth, com a cup member, a chambered cap mem er removably secured thereto, and a felt straining disk, one of said members? being provided rising with an internal annular shoulder against which one face of the outer margin of said straining disk engages, and the other member being provided with an annular edge which is adapted to be screwed into the first mentioned member to engage the opposite marginal face of said disk to clamp the same in position against said shoulder, an outlet pipe connected with the interior of said cap member, and an inlet pipe having its discharge mouth fiush with the underside of said disk and adapted to supply f'luidto said on member.

'n testimony whereof I hereunto affix my signature.
