SPECIFICATION forming part of Letters Patent No. 768,544, dated August 23, 1904. Application filed November 13, 1903, Serial No. 181,034. (No model.)
-To all whom, it may concern: 7
Be it known that we, Orro SELG and CARL GUNTRUM, both citizens of the United States, and residents of New York city, (Brooklym) county of Kings, and State of New York,-have invented new. and useful Improvements in Filters, of which the following is a specification.
This invention relates to a filter of great efficiency, which is not apt to become clogged andwhich may be readily and thoroughly cleaned.
In the accompanying drawings, Figure 1 is a front elevation of our improved liquid-filter; Fig. 2, a plan thereof; Fig. 3, a vertical section on line 3 3, Fig. 2; Fig. 4, a horizontal section on line L 4:, Fig. 3, with the stirrer omitted; Fig. 5, a detail of part of the stirrer; Fig. 6, an elevation, partly in section, of the upper part of the filter, showing the auxiliary lid in position; Fig. 7 a plan of such lid; and Fig. 8 a vertical section through the lower part of the filter, showing a modified construction of the outlet.
The letter (t represents a receiving-chamber for the liquid to be filtered, such chamber having inlet-nozzles a and being adapted to be closed by an outer cover 5. The chamber a may be supported upon a suitable frame A by gudgeons 4 The cover I) is locked to chamber a by swinging bolts 1) and is provided with a nozzle 6 and a tapped central opening 6 The chamber a incloses a tapering screen 0, which merges at its lower end into a frusto-conical imperforate shell cl. The
I screen 0 and shell 0Z collectively constitute a filtering-chamber having a perforated upper side or section, which is embraced by the receiving-chamber a, and an imperforate lower side or section, that depends from such chamber. The filtering-chamber 0 d is filled with pulp or other filtering material 6.
The screen 0 is removably secured in position by means of an open tapering frame which is fitted concentrically within chamber a. This frame consists of an upper ring f, a lower ring f, and a series of inclined ribs f that embrace screen 0.
Upon the frame is" adapted to be supported a perforated inner cover 9, which is placed at a distance from the outer cover 6, so that the liquid to be filtered can pass to the filtering-chamber through the screen 0 as well as through the cover 9.
A gasket h is interposed between cover 9 and ring f, while a second gasket h is interposed between ring fl and the bottom of chamber a.
The inner cover 9 is adapted to be pressed against its seat by a tubular plug 71, having a threaded lower end c", which engages the tapped opening 5 of cover Z). This plug may be rotated by a handle '17 and bears'upon a solid center piece 9 of coveng. A stufiingbox 7' is fitted to cover 6 and embraces plug c'.
The lower contracted end of shell d is provided with an outlet-nipple is, which also serves as a support for the filtering material 6. Upon the upper end of this nipple is arranged a small outlet-chamber Z, which tapers in a direction opposite to that of shell 0?. The chamber Z is provided with a screen Z, secured to a series of inclined ribs Z These ribs are attached at their upper end to a cap Z and at their lower end to a threaded ring 1*, which is tapped into nozzle 70.
The liquid to be filtered enters chamber a through opening a, and thence passes through screen a and cover 9 to the filtering-chamber, where'it percolates through the pulp. The filtrate is discharged through screen Z into chamber Z and out through nipple 7c.
. To wash the filter, water is admitted from time to time through the nipple 7c and is forced through the filtering-chamber to be ejected into chamber a and thence outthrough nozzle 6 the inlet a being closed. While the filter is being washed, it is desirable to stir the pulp e. To this effect there is mounted within the filtering-chamber a suitable number of rods or stirrers m. These rods are arranged in sets and and are inclined in conformity with the taper of thefiltering-chamber. Each'set of rods m is connected 'to a-common radial arm n, which is mounted upon a spindle 11, passing axially through the apparatus. The
arms n are inclined to a horizontal plane, so that when they are rotated in the direction of the arrow, Fig. 5, they will tend to move the pulp downward against the current of ascending water.
The spindle a is stepped upon cap Z and projects, with its upper end, through covers 9 7) and through the bore of plug 2'. A handle 72/ permits the spindle to be rotated, while a stufiing-box d is fitted upon plug 11 to embrace the spindle. WVhile the rinsing-Water is forced through the pulp in the manner described the handle 91 1's slowly rotated, so that the stirrers will agitate the pulp and subject all particles thereof to the action of the water.
In Fig. 6 is shown an auxiliary lid 0, which is adapted to be fitted upon the chamber a while the pulp is being filled into the filter. During this operation the covers 6 and g are removed and are replaced by the lid 0. This lid is of annular form and has a central opening above the filtering-chamber. The lid excludes the pulp from chamber a during the charging of the chamber 0 (Z. An inner depending flange 0 on lid 0, bearing against screen 0, holds the lid in position. In order to support the spindle n, the central openin of lid 0 is spanned by a perforated bridge 0*.
Fig. 8 shows a modification of the outlet for the filtrate. Here an annular foraminated bottom for the support of the pulp is fitted into the lower end of shell d. A plug 9, tapped into nipple It is provided with a chamber 11 below the screen and projects a distance above the screen, Where it tapers in a direction opposite to the taper of shell d. The filtrate flows from shell (Z, through screen 1), into a pocket 0'', and thence through ports Q2, into chamber q, and out through nipple it.
It will be seen that with our improved filter the liquid enters the filtering-chamber from its side as well as from the top. In this way clogging is prevented, and the filter will remain operative for a long time without requiring cleaning. While bcingcleaned, however, the stirrers will so agitate the pulp that the rinsing-water will wash outall impurities in a quick and eflicient manner.
What we claim is 1. A filter composed of a receiring-chamber, a screen and a perforated inner cover remorably fitted within said chamber, a shell bcneat h the screen, filtering material within the screen and shell, an outer cover, and a plug that passes through the outer cover and engages the inner cover, substantially as specified.
2. A filter composed of a receiving-chamber, a screen and a perforated inner cover within said chamber, a shell beneath the screen, filter ing material within the screen and shell, an outer cover, and a stirrer having a spindle that projects through the covers, substautiall as specified.
3. Afiltercomposedofareceiving-chamher, an inclosed frame, a screen secured thereto, shell below the screen, an inner perforated cover adapted to engage the frame, an outer cover having a tapped opening, an inclosed tubular plug engaging the inner cover, av stirrer having a spindle embraced by the plug, and filtering material within the screen and shell, substantially as specified.
