UNITED STATES PATENT OFFICE.
ISIDOR BEACH, OF PHILADELPHIA, PENN SYLVANIA;
IMPROVEMENT IN WATER-FILTERS.
Specification forming part of Letters Patent No. 182,638, dated September 26, 1876; application filed August 25, 1876.
To all whom it may concern:
Be it known that I, ISIDOR BEACH, of Philadelphia, Pennsylvania, have invented certain Improvements in Water-Filters, of which the following is a specification:
My invention consists of certain improvements, fully described hereafter, in that class of filters in which a filtering-disk is confined between two parts of a casing, my invention being directed to improvements in the filtering-disk, in the construction of the casing, and in devices for connecting the filter to a pipe.
In the accompanying drawing, Figure l is a view partly in section of my improved filtor; Fig. 2, a view of the filtering-disks, part of one of the disks being removed in order to show the intervening wire-gauze; Fig. 3, a sectional view of the filtering-disks drawn to an enlarged scale; and Fig. 4:, an enlarged view, showing the mode of constructing the casing.
The filtering-disk consists of two pieces, a and a, preferably of felt, with an intervening piece, b, of wire-gauze. D is a rubber band, placed over the edge of the filtering-disk, and overlapping the same, as seen in Fig. 3.
The wire-gauze may be omitted, but I prefer it for the following reasons: First, it maintains the filtering medium in a comparatively stiff condition; and secondly, the meshes of the wire-gauze present cells in which can be lodged charcoal or other filtering material.
By making the rubber band in one piece, overlapping the filtering-disk, three objects are attained: First, it serves to maintain the several parts of the filtering-disk in acompactcondition ready for sale and use; second, it presents an efficient packing medium for the flanges of the two parts B and B of the easing; and third, it prevents leakage at the edge of the filtering-disk.
Each of the two parts B and B of the casing of the filter is constructed in the following manner: Each part consists of the sheetmetal body at, screw-thimble e, and grate f.
This grate is secured to the body in the manner best observed in Fig. 4, the said body being of sheet metal spun up and bent over the edge h of the grate, which is thus firmly secured to the said body. At the same time a rigid flange, m, is formed. The filtering-disk is confined between the flanges of the two parts B and B of the casing by means of clamps we, each clamp being hinged at one end to the flange of the part B of the casing, and having at the other end a thumb-screw, t, for bearing against the flange of the other casing.
I provide each filter with a coupling device, H, consisting of the tubular metal screw I, short rubber tube J, and a hinged metal clamp, K. The tubular screw I is adapted to the screw-thimble e of either part of the casing, and one end of the short rubber tube J is bound to a projection on the tubular screw I by a wire, to, or otherwise.
By means of the clamp K the outer end of the rubber tube J can be expanded or contracted to suit pipes of different sizes.
I claim as my invention 1. The within-described filtering-disk, composed of two pieces, a and a, of felt or other filtering fabric, and a rubber ring, D, lapped over the edge of the disk, all as set forth.
2. The combination of the two pieces a and a of felt, intervening piece I) of wire-gauze, and the rubber ring I).
3. The within-described filter-casing composed of two parts, B and B, each part consisting of the screw-thimble e, grate f, and sheetmetal body d, secured to the thimble lapped over the edge of the grate, and forming with the latter a flange, m, all as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ISIDOB BEACH.

HENRY HowsoN, J r., HUBERT HowsoN.
