Nov.,26, 1935. J. WARDLE I APPARATUS FOR STRAINING LIQUIDS OR GASES Original Filed July 9, 1932 INVENTOR JOHN WARDLE ATTORNEYS Patented Nov. 26, 1935 PATENT OFFICE APPARATUS FOR STRAINING LIQUIDS GASES John Wardle, Westminster, London, England, assignor to Lolos Strainers Limited, Barrow-in- Furness, England, a British company Original application July 9, 1932, Serial No.
621,600. Divided and this application July 1, 1933, Serial No. 678,690. In Great Britain October 14, 1931 6 Claims. (01. 210-167 This invention relates to apparatus for straining liquids or gases and its chief object is to provide a mechanical cleaning device for the straining medium.
In order that the said invention may be clearly understood and readily carried into effect the same will now be described with reference to the accompanying diagrammatic drawing and will be defined in the appended claims.
In the drawing:-
Figure 1 is a central vertical section of one form of strainer provided with a cleaning device in accordance with this invention; 7
Figure 2 is an enlarged View of part of the cleaning device shown in Figure 1;
Figure 3 is a section on line II--II on Figure 1;
and
Figure 4 is a section illustrating a modification in which the cleaning elements are located within the strainer body.
In Figures 1, 2, and 3, the strainer body A is formed peripherally with longitudinally disposed ribs at around which the wire A is wound spirally, and with longitudinal slits, grooves, or the like, (not shown) for the passage of the liquids. or gases. The cleaning device comprises toothed or notched discs X that engage between the convolutions of the wire A and gear with the ribs a. The discs X are carried by a spindle X The discs X may be formed as independent elements and spaced apart by distance pieces X or they may be formed integrally with each other and withthe distance pieces X (and with the spindle X also if desired) by forming a toothed cylinder and cutting slots in the teeth for the reception of the convolutions of wire. The spindle X is mounted in the casing E so as to be capable of axial sliding movement or the discs or cylinder may be axially slidable on the spindle X The strainer body A and cleaning device are located within the casing E which has an inlet opening E outlet opening E and a sump E The strainer body A is journalled at A A in the casing E and at A is provided with apertures A, through which the liquid or gas from the inlet EPenters into the interior of the strainer body A and passes between the convolutions of wireA to the outlet E The strainer body A is also provided with a spindle A that extends through an aperture in the upper wall of the casing E and has a handle A on its outer end. Rotation of handle A causes the strainer body A and cleaning device to rotate so that any foreign matter located between the convolutions of wire is dislodged into the interior of the body A whence it falls into the sump E from which it can be removed after detaching a screw plug E During such rotation the convolutions of wire cause the discs X or spindle X to move axially.
Figure 4 illustrates a modification in which the cleaning elements or discs X are mounted within the strainer body the teeth a of which latter are accordingly formed of increasing cross-sectional area towards their outermost surfaces, the teeth on the discs X also being suitably shaped. In this arrangement the gas or liquid will pass between the convolutions of wire A from the outside to the interior of the strainer body and the dirt will be pressed by the discs X to the outside of the strainer body when the latter and the discs X are rotated.
What I claim and desire to secure by Letters Patent of the United States is:-
1. Apparatus for straining fluid comprising a cylindrical strainer body provided with passages for the fluid, and having a helical groove on its outer surface, a straining medium consisting of a wire wound in said helical groove, and mechanical cleaning devices provided with teeth which pass between adjacent convolutions of the wire and which enter said passages thereby gearing with said'body.
2. Apparatus for straining fluid comprising a rotatably mounted cylindrical strainer body provided with longitudinal openings for the fluid and with a helical groove on its outer surface, a straining medium consisting of a wire wound in the said helical groove, a spindle parallel to but offset from the axis of the cylindrical strainer body, and toothed cleaning devices mounted on said spindle and provided with teeth which pass between adjacent convolutions of the wire and enter said openings thereby. gearing with said strainer body.
3. Apparatus as in claim 2, wherein said spindle is mounted within the strainer body and means are provided whereby the normal flow of fluid occurs from outside the strainer body through the straining medium into the interior of the strainer 7 body.
is mounted outsidethe strainer body and means are provided. whereby the normal flow of fluid occurs from the interior of the strainer body through the straining medium to the exterior of the strainer body.
5. Apparatus as in claim '1 wherein the cleaning devices comprise integral projections of a slotted and toothed cylinder.
6. Apparatus for straining fluid comprising a 45 4. Apparatus as in, claim 2 wherein said spindle cylindrical strainer cage provided with a surrounding helical groove and provided with a straining medium including a wire wound in said groove forming fluid passages opening to the cage interior between adjacent convolutions of the wire, mechanical cleaning means provided with teeth entering passages between the wire 7 convolutions and means for rotating said cage and straining medium and thereby causing circumferential movement of said cage and straining medium with respect to the cleaning means and axial movement of the cleaning means with re- 5 spect to the cage and straining medium.
JOI-IN WARDLE.
