Improvements in or relating to Water-filters.
I, SEATON MARSBA BOYER, of 1136, Hamilton Street, Allentown, Pa., United
States of America, Manufacturer, do hereby declare the nature of this invention
to be as follows:
This invention relates to water-filters, but more particularly to an agitating
attachment for water-filters, the object of the same being to provide means for
mechanically & thoroughly agitating or stirring up the filtering material con-
tained in the filtering tank so that foreign bodies which have been intercepted
by the filtering material will be detached or loosened therefrom & the more
readily carried off when cleaning the filter.
In the acompanying drawing,
Fig. 1 is a sectional side elevation of a water-filter, according to my present
invention.
Fig. 2 is a detached side view of the agitating attachment, and
Fig. is a transverse section on line 3-3 Figure 1.

Referring to the drawing, A represents a suitable tank, B an inlet-pipe, & C
an outlet pipe, leading respectively to the top & bottom of the tank.
top & bottom of the tank are perforated screens S, S¹, for holding the filtering
material in place. The inlet-pipe is connected to the outlet pipe C by a connecting
pipe D. Valves 133, 1¹ & C, are arranged in the inlet-pipe B, connecting pipe D
& outlet pipe C, so that by opening the valves B2 & C, with D' closed, the water
to be filtered passes down through the mass of filtering material in the tank A. &
pure water passes off through the outlet-pipe C in the well-known manner.
clean the filtering material of foreign substances separated from the water by
the same, the valve B2 is closed, & valves C¹ & D¹ opened, so that by a reverse
current passing up through the filtering material, the water effectually takes
along with it the foreign substances & carries the same out through the valves
outlet E for the impure or cleansing water. So much of the filter is known,
but the present invention relates to a mechanical agitator whereby the filtering
material is thoroughly stirred up & agitated while the cleansing water is passing
through, so that all the foreign particles detached are carried off.
In carrying out my invention, diametrically-opposite bearings are provided
in the upper part of the tank A, & in these the crank-shaft H turns, said shaft
having outside the tank a hand-crank h. A rod or shank composed of two
section I, I, is pivoted to & hung from the cranked portion of the shaft H so as
to extend nearly to the bottom of the tank, & from these sections extend radial
agitator-arms or blades i, which are arranged in any suitable manner, as for
instance spirally, around & upon the said sections. The said sections I, I', are
hinged or pivotted together at j, & inasmuch as the arms on the lower section I¹
are somewhat longer than those on the upper section I, the rotation of the
hand crank will impart a straight, up & down, reciprocating motion to said lower
section, while a rocking or wobbling motion will be imparted to the upper section.

page_text: This motion is imparted while the cleansing water is being passed upwardly
through the filter. It will be understood that the heavier & coarser particles of
foreign matter will, in filtering, have been detained by the filtering material at
the upper part of the tank in which the upper wobbling section of the agitator
attachment is arranged, & for this reason the attachment is composed of pivoted
parts so that a more vigorous stirring up of that portion of the filtering material
may be effected. As less foreign matter is detained by the lower mass of filtering
material, a simple reciprocatory motion is imparted to the lower section.
The radial arms on the depending agitator thoroughly detach all foreign
particles & enable the cleansing water to thoroughly & effectively clean out or
wash the filtering material preparatory to filtering again.
The attachment can readily be applied to filters of the type shown, as it is
only necessary to mount the bearings at the upper part of the tank, before
putting in the attachment. Consequently the attachment can he sold either
iogether with the other parts of the filtering apparatus or. independently.

I, SEATON MARSBA BOYER, Manufacturer, of 1136, Hamilton Street, Allentown,
Pa., U.S.A., do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This invention relates to water-filters, but more particularly to an agitating
attachment for water-filters, the object of the same being to provide means
for mechanically and thoroughly agitating or stirring up the filtering material
contained in the filtering tank, so that foreign bodies which have been intercepted
by the filtering material will be detached or loosened therefrom and the more
readily carried off when cleaning the filter.
Referring to the drawings left with the Provisional Specification in this case:
Fig. 1 is a sectional side elevation of a water-filter, according to my present
invention.
Fig. 2 is a detached side view of the agitating attachment, and
Fig. 3 is a transverse section on line 3-3 Fig. 1.
Similar letters of reference indicate corresponding parts.
Referring to the drawing, A represents a suitable tank B an inlet pipe, and C
an outlet pipe, leading respectively to the top and bottom of the tank. At the
top and bottom of the tank are perforated screens S, S¹, for holding the filtering
material in place. The inlet pipe is connected to the outlet pipe C by a connecting
pipe D. Valves B2, D and C', are arranged in the inlet pipe B, connecting
pipe D and outlet pipe C, so that by opening the valves B and C, with D¹ closed,
the water to be filtered passes down through the mass of filtering material in
the tank A and pure water passes off through the outlet pipe C in the well-known
manner. To clean the filtering material of foreign substances separated from
the water by the same, the valve B2 is closed, and valves C and D opened, so
that by a reverse current passing up through the filtering material, the water
effectually takes along with it the foreign substances and carries the same out
through the valves outlet E for the impure or cleansing water. So much of

page_text: the filter is known, but the present invention relates to a mechanical agitator
whereby the filtering material is thoroughly stirred up and agitated while the
cleansing water is passing through, so that all of the foreign particles detached are
carried off.
In carrying out my invention, diametrically opposite bearings are provided
in the upper part of the tank A, and in these the crank-shaft H furns, said shaft
having outside the tank a hand-crank h. A rod or shank composed of two
sections I, II, is pivoted to and hung from the cranked portion of the shaft H so
as to extend nearly to the bottom of the tank, and from these sections extend
radial agitator arms or blades i, which are arranged in any suitable manner, as
for instance spirally, around and upon the said sections. The said sections I, I¹,
are hinged or pivoted together at j and inasmuch as the arms on the lower
section I¹ are somewhat longer than those on the upper section I, the rotation
of the hand-crank will impart a straight, up
cating motion to said lower section, while
and down, recipro-
will be imparted to the upper section. This motion is imparted while the cleansing
a rocking or wobbling motion
water is being passed upwardly through the filter. It will be understood that
the heavier and coarser particles of foreign matter will, in filtering, have been
detained by the filtering material at the upper part of the tank in which the
upper wobbling section of the agitator attachment is arranged, and for this
reason the attachment is composed of pivoted parts so that a more vigorous
stirring up of that portion of the filtering material may be effected. As less
foreign matter is detained by the lower mass of filtering material, a simple
reciprocatory motion is imparted to the lower section.
The radial arms on the depending agitator thoroughly detach all foreign par-
ticles and enable the cleansing water to thoroughly and effectively clean out or
wash the filtering material preparatory to filtering again.
The attachment can readily be applied to filters of the type shown, as it is
only necessary to mount the bearings at the upper part of the tank, before
putting in the attachment. Consequently the attachment can be sold either
together with the other parts of the filtering apparatus or independently.
Having now particularly described and ascertained the nature of my said
nvention and in what manner the same is to be performed, I declare that what
I claim is:―
1. An agitating attachment for filtering apparatus, consisting of a hinge-jointed
od or shank provided with radial agitator arms, substantially as set forth.
2. An agitating attachment for filtering apparatus, consisting of a cranked-
haft, a hinge-jointed rod or shank hung on the cranked portion of the shaft, and
adial arms on said rod, substantially as set forth.
3. In combination with a water-filtering tank, and means for supplying cleansing
iquid thereto, a reciprocating agitator arranged in the tank and having a wobbling
r rocking upper section, and means for reciprocating said agitator, substantially
s set forth.
4. In combination with a water-filtering tank, and means for supplying clean-
ing liquid thereto, a reciprocating agitator arranged in the tank and composed of
ivoted sections provided with radial arms, and means for reciprocating said
gitator, substantially as set forth.
