JOHN CHARLES BARKER, OF LEEDS, ENGLAND.
WATER-FILTERING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 794,840, dated July 18, 1905.
Application filed November 2, 1904. Serial No. 231,094.
- ain, and a resident of 26 and 27 Bond street,
Leeds, in the county of York, England, have invented certain new and useful Improvements in VVater-Filtering Apparatus, of which the following is a specification.
This invention relates to an apparatus for filtering drinking-water, which can be placed directly on domestic water-pipes, either high or low pressure. I prefer to place it on the pipe just above the kitchen-sink, so that the apparatus may give filtered water for drinking purposes and unfiltered water for common use.
In order that my said invention may be properly understood, I have hereunto appended explanatory sheets of drawings showing the apparatus. I
Figure 1 is a side view of the water-filtering apparatus, partly in section. Fig. 1 is a view of the pipe-coupling. Fig. 2 is an end View of the hemispherical shell with the filtering material and the cover it removed. Fig. 3 is a part section showing a slight modification. Fig. 4 is a section of a further slight modification.
The apparatus consists of an ordinary service-cock a, a hemispherical shell hinclosing the filtering material 0, (this shell has a screwed tubular extension (Z, which is connected by the coupling g to theWater-pipe) a tubular piece a,inserted at the interior of the aforementioned extension and which terminates at the inside of the shell in a head a, which is pierced by a number of small radial holes 6 for the passage of the water into the shell, and a small cock f at the lower side for running off the filtered water. The shell is closed by a disk h, which is screwed in place and which possesses a central tubular extension 6, screwed on the inside and into which the cock (0 is screwed.
The filtering material 0 consists of spun asbestos and is woven specially for the purpose of making a very thick and compact tissue, Which swells upon contact with water to such an extent that no organic body or matter carried by the water can penetrate it. The asbestos tissue is not liable to sufl er from the action of water. A strengthening and supporting shield of metal gauze 0, as shown at Fig. 1, is fitted at the back of the asbestos tissue. Instead of using wire-gauze I may use perforated metal, as shown at a, Fig. 3.
The filtering material 0 and strengtheningshield are preferably made in the shape of a hemispherical cup and placed in the apparatus. The circumferential edge of this cup is, as shown, tightly pressed and held by the disk 70, while at the center the cup is held securely in position against the internal projecting part 7' of the shell 6 by means of the screwed tubular piece 6.
In order to prevent the filtering material bedding on the inner surface of the shell 5 on account of the pressure of the Water, and thereby retarding the proper flow of filtered water through the cock f when the latter is opened, the shell .7) is made with the internal projecting part 7', as well as a ring or rings m, Fig. 4, or a series of projections Z, Fig. 3. The projections or ring, as the case may be, supports the shield at a distance from the outer shell 6. With this construction the filtration of the water is greatly facilitated, as the unfiltered water passes readily through the filtering material 0 and Wire-gauze 0 into the annular space 70, from whence it may be drawn off as desired by the cock f.
If desired, a series of grooves Z2 may be made in the shell 5 and arranged to communicate with each other and with the passage f, leading to the cock f. When these grooves are made in the shell, the projecting part y may be dispensed with or reduced in height and the filtering material allowed to rest more or less on the internal surface of the shell. The grooves are made sufiiciently deep 'to allow the filtered water to run freely, and the gauze strengthening-shield 0 prevents the asbestos tissue 0 bedding in the grooves b.
When the small cock f is opened, the water from the supply-pipe enters the shell 6 by the holes 0 and filters slowly through the filtering material 0 into the annular space 76, thereafter passing out by the cock f. The impurities are deposited upon the interior surface of the material 0. When the cock f is closed roo and the cock (0 opened, the water runs at full pressure through the apparatus and by the cock (4. The water-jets passing through the radial holes 0 impinge upon the surface of the filtering tissue 0 and sweep away any impurities collected thereon from the last filtration, so that a cleansing action takes place each time the cock (0 is opened for the passage of water for ordinary use, with the result that the apparatus never becomes choked.
Instead of using asbestos tissue any other well-known and suitable water-filtering substance can be used in the apparatus. For instance, natural or artificial porous earths, porcelains, or biscuit wares, or other bodies at present employed for the filtration of water may be used. The filtering substance would of course be made or molded into the form of a cup, such as 0, so as to fit into the apparatus.
Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. A filter comprisinga dished-shaped containing member, a nipple for said member projecting in opposite directions from its juncture therewith, said nipple being adapted for direct connection with a service-pipe, a thimble located within said nipple having a relatively enlarged head provided with radial apertures communicating with a central bore in the nipple, a diaphragm of filtering material having an aperture through which said thim- 2. A filter comprising a containing member,
a nipple for said member, said nipple being adapted for direct connection with a servicepipe, athimble located within said nipple having a relatively enlarged head provided with radial apertures communicating with a central bore in said nipple, a diaphragm of filtering material having an aperture through which said thimble passes, said diaphragm being clamped between the head of said thimble and nipple, a closing-plate secured to said containing member serving to clamp the periphery of said diaphragm in place, said diaphragm thereby dividing the dished-shaped member into two compartments, and a service-cock for each of said compartments.
