FILTER.

Application led March 10, 1927. Serial No. 174,243.

through, the construction of the insert being such that it may be easily and inexpensively manufactured, may be easily positioned within the filter casing, and will be unusually efficient.

lVith the foregoing in view, the invention resides inthe novel subject matter hereinafter described and claimed, lthe description being supplemented by the accompanying drawings. j

Fig. 1 is a perspective view illustrating one of the steps in the construction of the filtering insert.

Fig. 2 is a perspective view of the filtering insert in a condition which, in the present disclosure of the invention, is only a partially completed condition.

Fig.v 3 is a perspective view of the two open-work cylinders and an open-work end plate which are employed in the construction of the filtering unit.

Fig.- 4 is a side elevation with parts disassembled, showing the casing for the filtering unit and the associated spigot.

Fig. 5 is a longitudinal sectional viewshowing the filtering unit confined within the casing. i

Fig. 6 is a transverse sectional view on line 6 6 of Fig. 5.

In the drawings above briefiy described, the numeral 7 designates an open-work cylinder, preferably formed of perforated metal, of such quality that it will resist rusting or corrosion.

The numeral 8 denotes a textile fabric strip which is circumferentially wound a plurality of times around the cylinder 7, said strip being `of a width considerably greater than thelength of said cylinder. Thus, when one edge of the strip is placed `substantially flush with one end of the cylinder and said strip is wound as above described, a surplus of fabric 9 will exist at the other end of said cylinder, and this surplus is inwardly turned and stuffed into the last named cylinder end, as will be clear from Figs. 2, 5 and 6.

cylinder 7, preferably surrounds the wrapped `fabric strip and holds all4 parts in assembled relation.

In the preferred construction, an openwork plate or disk 11 is provided at the end of the cylinderV 7, remotefrom the surplus fabric 9, and in the embodiment herein illustrated, said disk or plate constitutes a screen for the inlet end of the cylinder 7.

A casing is provided to contain the filtering unit above described. This casing, shown in Figs'. 4, 5 and 6, embodies a cylindrical wall 12 having an outlet spout 13 at one end and a transverse spider or the like 14 near said end. The other end of the casing wall 12 has threaded engagement with a` closure 15, which closure is provided with a threaded inlet nipple 16 for engagement with the outlet of a faucet 17.

be interposed between the opposite end of said unit and the closure 15. The disk or plate 11 may then be held between this washer and the adjacent end of the inner cylinder 7, and the outer cylinder l0 is then preferably spaced a slight distance from the casing wall.

Due to the novelconstruction shown and described, the water or other liquid must pass both through the open-work members and through a number of thicknesses of textile fabric, and a great deal of the water will flow edgewise of the fabric strip,`that is longitudinally between the cylinders 7 and 10. Hence, effective filtering will be` produced. Obviously, some of the liquid will also ooze through the inturned surplus of textile material 9 and will be effectively filtered thereby.

As excellent results are obtainable from the general construction shown, it is preferably followed. However, within the scope of the invention as claimed, variations may of coursebe made.

Cbviously, when the filter becomes totally or partially clogged, the filtering unit or insert may be removed and readily cleaned and may have a new strip of fabric substituted for the strip previously used. Then, when this unit is replaced, the filter will function as efficiently as if entirely new. Y

1 A filter comprising a casing having a central Water inlet at one end and a water outlet, one open-Work hollow cylinder in said casing having an end communicating with Said inlet and the other end with said outlet, and a strip of textile fabric Wrapped a plurality of times around the circumference of said cylinder, said strip being of a Width greater than the length of the cylinder, providing a surplus of fabric at the other end of the cylinder, said other end being open, said surplus of fabric being' turned inwardly and stuffed into the cylinder through said open end.

2. A filtering insert comprising an openwork hollow cylinder. and a Strip of textile fabric circuinferentially Wrapped a plurality of times around said cylinder, the aforesaid cylinder being open at one end. said fabric strip being of a width greater than the length of the cylinder, providing a surplus of fabric at said open end of the cylinder, said surplus of fabric being inwardly turned and stuffed into said open end of the cylinder.

A structure as Specified in claiin 2; t0- gether with an open-work sleeve surrounding the wrapped fabric.

4. A filtering insert embodying textile fabric applied to the outer side of an openwork cylinder and stuffed into and c0Inpletely illing an end thereof said stuffed in fabric forming additional liltering means.

In testimony whereof I have hereunto affixed my signature.
