appiieation' sied my 1, 191,0, serial No.' 569,900

To all 'whom t may'conow'n.' I A Be it known that I, EDWARD Knrinnnn, a citizen of the United States of America, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Hose-Nozzles, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to a hose nozzle provided with a strainer and an automatic cut off in proximity to the strainer adapted to control the flow of liquid therethrough, the cut olf being so mounted and governed as to provide for its preventing How of liquid through the strainer when there is absence of pressure in the strainer housing and adapted to be opened by virtue of liquid under pressure introduced into the strainer housing and flowing therefrom through the strainer and past the cut-olf.

lThe drawing is in part a longitudinal s ection and in part an elevation of my device.

In the drawing:-1 designates an elongated cylindrical strainer housing having a correspondingly shaped chamber 1a and to one end of which a hose 3 is connected by a screw threaded end 3a engaging the internally screw threaded neck of the strainer housing. The strainer housing is provided at its end opposite that to which the hose 3 is connected with an internally threaded head 2.

4 designates a valve housing provided with a screw threaded neck 5 fitted within the internally screw threaded head p of the strainer housing l. At the upper end of the neck 5 is an annular ange 6.

7 is an elongated strainer, preferably of frusto-conoidal shape occupying the housing chamber Ila and the lower open end of which is fitted and attached to the ange 6 so that it is held centrally within the strainer housing. At the bottom of the neck of the valve housing 4 is a valve seat 8.

9 is a cut-olf valve arranged in the valve housing 4 and normally held against the valve seat 8 by an expansion spring l0. The stem 9 of the cut-off valve is slidably mounted in an annulus 11b in the spider 11a of a valve supporting ring 11 in which the valve stem 9 is slidably fitted. The annulus 11b has a reduced portion 11c providing a seat for the expansion spring 10. The valve supporting ring 11 is screw threaded at its upper partso as to fit in theinternallyscrew threaded lower part of the valve housing 4 and lits lower part has a screw threaded neck.

12 is a discharge pipe attached to the screw threaded neck of the valve supporting ring and normally in communication therethrough with the interior of the valve housing 4.

In the practical use of my strainer and cut off, the cut olf valve 9 is normally maintained in a closed position through the mediumv of the spring 10 so that the face of the valvev rests against the valve seat 8 and prevents the flow of liquid that is not under pressure from the interior of the strainer housing to the valve housing, and therefrom to the discharge pipe. When, however, liquid is conducted under pressure through the hose 3 to the strainer housing, it is forced through the Strainer 7 and pressure against the cut off valve 9 causes said valve to be unseated, with the result that the liquid, immediately after being strained, is permitted to flow to the discharge pipe and be delivered therefrom to t-he point at which delivery of the strained liquid is to be made. It will be apparent that limmediately upon the discontinuance of exertion of pressure upon the liquid in the strainer housing, the cut oft1 valve is returned to its seat by virtue of the action thereagainst of the spring 10 discontinuing flow of the liquid from the strainer housing.

My strainer and housing is primarily intended for use in strainin gasolene that is to be placed in the tanks o automobiles, and in such use of the device the hose 3 attached to a suitable type of pump used in connection with a gasolene reservoir, and the pressure for forcing the gasolene through the strainer and opening the cut olf valve 9 is, therefore, obtained in the operation of said pump. It is obvious, however, that the strainer and cut off may be used for straining other liquids than gasolene and for use in other instances than that herein specically mentioned.

I claim A hose nozzle of the character described comprising an elongated strainer housing having a correspondingly shaped chamber, and formed with an internally screw threaded neck at one end and an internally screw threaded head at the other end, a valve housing having a screw threaded neck at one end fitting the internally screw threaded head of the strainer housing, and provided with an annular flange and an internal screw thread at the other end, a strainer of -rustoconoidal shape fitted to the annular flange, a Valve supporting ring seating against the outer end of the Valve housing having a screw threaded inner part fitting the internal screw thread of the valve housing and a spider formed with an annulus, a spring cutofic valve having a stem slidable in the an- 10 nulus and a spring seating around the annuius between the spider and the valve.
