FILTER.

Specification of Letters Patent.

Patented New. ao, aait.

Application filed August 24,1917. Serial No. 187,991.

To all whom t may concer-n:

Be it known that I, HENRY KERSHAW, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Filters, of which the following is a specification.

The filter which is the subject matter of the present a-pplication for patent is designed more particularly for use in connection with motorcycles and cars for the purpose of assuring a clean supply of gasolene t0 the carbureter, the filter being interposed in the pipe line leading from the gasolene supply tank to the carbureter. A

The invention has for its object to provide 'a simple and eflicie'nt filter of the kind stated, which can be readily installed, and which isso constructed that it can be easily taken apart for cleaning, repairs, etc.

With the object stated in view. the invention consists in a novel combination and arrangement of parts to be hereinafter de'- scribed and claimed, and in order-that the same may be better understood reference is had to the accompanying drawing, forming a part of this specification.

In the drawing,

Figure 1 is a perspective view of the filter;

Fig. 2is a central vertical section thereof; and Figs. 3 and 4 are cross sections on the lines 3-3 and 4 4, respectively, of Fig. 2.

Referring specifically to the drawing, 5 denotes a filtering vessel in the form of an upright cylinder having a closed bottom 6 and a top closure 7, the latter being a screw cap. The cap 7 does not seat directly over the top of the vessel 5, but is detachably connected to a neck 8 carried by the latter. This neck is a ring having top and bottom reduced portions which are screw-threaded, the for- 111ery receiving the cap, and the latter beingscrewed into the top of the vessel, the parts being thus all separably.connected. x

The bottom 6 of the vessel 5 is provided with an inlet nipple 9 for connection to the gasolene line, and it is also fitted with a drain cock 10.

In the vessel 5 is mounted and fitted snugly therein, a glass cylinder 11', :the side of the vessel has an opening 12 exposingv said cylinder and forming a sight opening through which the fluid level in the vessel may be observed. The glass cylinder seats on the bottom of the vessel and it is held in the vessel by the neck 8, the bottom edge of the latter having an inturned marginal Iflange 13 seating on the top edge of the cylinder. Thus the lglass rcylinder is `firmly held when the neck 8 is screwed down on the vessel. Between the top edge of the neck 8 and the under side of the cap 7 is interposed a gasket 14. The outer surface of the cap isy formed square to permit app lication of a Wrench or other tool for putting on or taking ofi' the cap.. y

In the neck 8 snugly fits a sleeve 15 the same resting on the flange 13 and being kept from turning in the neck by a cross bar or pin 16 which projects at its ends from the outer periphery of the sleeve to seat in ver tical grooves 17 in the wall of the neck on the inside therof.

In the sleeve 15 are mounted two strainer disks 18 of ine gauze, with a thick felt pad 19 therebetween.

Above the top strainer disk 18, the sleeve 15 has a side aperture 20 registering with an outlet nipple 21 on the neck 8. to which nipple is connected a piping which leads to the carbureter. As the cross bar 16 prevents the sleeve 15 from rotating, the aperture 2O remains in line'with the nipple 21.

The gasolene line from the supply tank (not shown) is connectedtothe inlet nipvple 9, and said tank being positioned above ythrough the strainer disks 18 and pad 19,

and thence escaping through the outlet 20, to be carried to the carbureter. By its passage through the water the gasolene will be relieved of heavy dirt particles, and a further straining action takes? place when the gasolene passes through the strainer elements 18 and 19, the latter intercepting and holding any water which may be present in the gasolene, and thereby assuring isolation of water if thetwo liquids should be 4agitated by excessive jar so as to splash the water to the strainer elements. The Asediment collecting in the bottom of the vvessel can be run out by opening the drain cock 10. The entire apparatus can also be Now `when the gasolene l cleaned out by removing the sleeve which can be readily done aftertaking the cap 7 0E. ll claim :M 1. Afilter comprising a vessel having a bottom inlet and adapted to hold a Wash liquid, 'and having an outlet above the liquid level, a neck attached to the top of the ves sel and having an internal flange, a sleeve in the neck and seating on the Hange, a cap closing the neck and engaging the vsleeve to .hold the same seated on the flange, and a screen carried by the sleeve, said screen being located between the top of the liquid and the outlet of the vessel.

2. A filter comprising a vessel having a bottom inlet and adapted to hold a Wash liquid, and having an outlet above the liquid level, a neck attached to the top of the vessel and having an internal flange, a sleeve in the neck and seating on the flange, a cap closing the neck and engaging the sleeve to hold the same seated on the flange, a screen carried by the sleeve, said screen being le anaemia cated between the top of the liquid and the outlet of the vessel, the sleeve having an escape aperture in alinement with the outlet, and means for locking the sleeve against rotation. l

3. A. filter comprising a vessel having a bottom inlet and adapted to hold a Wash liquid, and having` an outlet above the liquid level, a neck attached to the top of the vessel and having an internal flange, a sleeve in the neck and seating on the flange, a cap closing, the neck and engaging the sleeve to hold the same seated 0n the flange, a screen carried by the sleeve, said screen being. located between the ton of the liquid and Athe outlet of the vessel, the sleeve having an escape aperture in alinement with the outlet, and pins projecting from the side of the sleeve, the interior of the neck having grooves in which the pins seat to hold the sleeve against rotary movement.
