S TRAINING OR FILTERING APPARATUS;
Specification of Letters Patent. Patented Apr, 25, 1922.
Application filed May 5, 1920. Serial No. 379,126.
has for its object to provide apparatus bywhich certain advantages shall be obtained. The invention relates more particularly to the construction of strainers having means for preventing the choking of the screens.
According to the present invention, a strainer for liquid comprises the combination with a straining wall, for example of cylindrical form having a slot or aperture through which the liquid is strained, of a scraper comprising a blade projecting into said said slot, and in permanent engagement therewith, the straining wall or scraper, or both, being movable so that the blade will traverse the slot or aperture. 7
Various forms of apparatus according to the present invention maybe constructed and some are illustrated in the accompanying? drawings, wherein,
ig. 1 shows a section of one form of strainer; and
Fig. 2 an end elevation thereof in section;
Fig. 3 shows an end elevation in section of a modified form of strainer;
Fig. 4 shows a section of a further modified form, and
Fig. 5 an end elevation in section thereof;
Figs. 6 and 7 show end elevations in section of strainers similar to that illustrated in Figs. 4 and 5;
comprises a cylindrical straining wall having four longitudinal slotsl at equal dis tances around its circumference. The cylindrical straining wall has end walls 2, 3 and is mounted loosely on a spindle l, on which is mounted a scraper having four blades 5 projecting outwardly one into each slot 1 and in permanent engagement therewith. The straining wall is enclosed in a housing '6 which has an inlet for the fluid to be strained '1.
Outlets 8 forthe fluid are provided in the end wall 3 of the cylindrical straining wall 1. -In operation, should the slots 1 through which theliquid is strained become choked, the spindle 4'is withdrawn from the housing so that the blades 5 traverse the slots 1 and clear them. If desired, the cylindrical straining wall and housing may be moved and the scraper blades 5 remain stationary, or both the straining wall and the scraper may be moved.
In the strainer shown in Fig. 3, the blades 5 are mounted on the'housing 6.
Referring to Figs. 4 and 5, the straining wall is built up of a series of'circular discs 9 having one or more annular ribs 10 and disposed axially one behind the other. The discs are mounted on the spindle 4 and the spaces between the ribs 10 and the discs 9 constitute the apertures through which the liquid is strained. Within these spaces are interposed a series of scraper blades 5, two
projecting. into each space and loosely mounted on the spindle 4. In use to clear the straining apertures the discs 9 areTro tated, the blades 5 being prevented from moving by stops 11 projecting from the housing 6; or the housing and with it the scraper, or both the scraper and the discs may be rotated.
In the modified apparatus shown in Fig.
the scraper blades 5 are secured to the hous-' ing 6 and one extends between each pair of discs.
'To clear the apertures the discs or the housing, and consequently the blades, may be angularly moved.
In the modified form of apparatus shown in Fig. 7 the scraper blades 5 are mounted on the spindle 4 and the discs 9 are loosely" mounted thereon and prevented from rotating relatively to the housing 6 by a projection 12 engaging with a projection from the housing.
In the strainer shown in Figs. 8 and 9 the straining wall consists of a cylinder 13 either the blades or the cylinder 13 may be angularly movable as is described with reference to the other figures of the drawings.
In Fig. 10 the straining wall is a cylinder 14 having a spiral groove 15 constituting the slot through which the fluid is strained. The blades 5 are slidably mounted on the spindle 4. To clear the passage 15 the blades are revolved and consequently traverse the groove 15.. In the modification shown in Fig. 12, the blade 5 isffixed to the housing and the drum 14 is rotatable and also longitudinally movable.
In the form of apparatus illustrated in Figs. 13 and 14 the scraper blades 5 are mounted on a disc 16 carried on a spindle 4 and project into the slots through which the fluid is strained, in the plate 17 forming part of the housingfi.
The apparatus according to the present invention may be operated by hand or by mechanical means; thus it may be operated through a coupling, belt, pulley, ratchet or other means, or it may be operated by the liquid passing through the strainer imping-. ing on a wheel carrying a series of vanes.
What I claim is 1. A strainer for liquid comprising in combination a cylindrical straining wall having a slot through which the liquid is strained,
and a scraper comprising a blade projecting into the said slot and in permanent engage-- ment therewith, one being movable relatively to the other so that the blade will traverse the slot.
2. A strainer for liquid comprising in combination .a cylindrical straining wall having a circumferential slot through which theliquid is strained, and a scraper comprising a blade projecting into the slot and in permanent engagement therewith, one being angularly movable relatively to the other so that the blade will traverse the slot.
3. A strainer for liquid comprising in combination a cylindrical straining wall having a plurality of circumferential slots through which the liquid is strained, and a scraper comprising a plurality of blades one projecting into each slot and in permanent engagement therewith, the one being angularly movable relatively to the other so that the blade will traverse the slot.
4. A strainer for li uid comprising in combination a cylindrica straining wall having a plurality of circumferential slots through which the liquid is strained and an outlet for the liquid, and a scraper comprising a plurality of blades one projecting into each slot and in permanent engagement there-with, one being angularly movable relatively to the other so that the blade will traverse the slot.
5. A strainer for liquid comprising in combination a plurality of discs each having an annular rib and spaced apart to form a cylindrical straining wall having circumferential slots through which the liquid is strained, and a scraper comprising a plurality of blades one projecting into each slot in permanent engagement therewith, the one being angular-1y movable relatively to ,the other so that the blade will traverse the slot.
