Improvements in Filtering Apparatus.
We, CARL GEORG EMIL SALZBERGER, Civil Engineer, of Leerstrasse 8,
Burgsteinfurt, Westfalen, Germany, and CARL KAPPESSER, Merchant, of Leer-
strasse 21, Burgsteinfurt, Westfalen, Germany, do hereby declare the nature of
this invention to be as follows:-
This invention relates to an apparatus by means of which water containing
mud and sand is purified the working of this apparatus being continual.
Figs. 1 and 2 are respectively transverse and longitudinal sections and Fig. 3
is a plan of apparatus according to our invention. Fig. 4 is a transverse section
of modified apparatus in which the water has to take a longer course.
Fig. 5 is a longitudinal section and Fig. 6 a sectional plan of a modification.
As shewn in Figs. 1 and 2 the conduit pipe R for leading purified water to
a well or reservoir is connected by a flange with a tubular axle a having two
or more lateral openings b.
A nave n, round which are arranged two or more chambers c d e f, is fitted
to revolve on the axle a. The chambers are separated from a and covered
outside by removable perforated plates or wire-gauze diaphragms g and gl.
One end of a has a cross h through which passes the reduced end of a bolt i.
The bolt which guides the cover has a cross hole to receive a bolt on which
pivots a lever m which is firmly connected with two eccentrics o.
By the
movement of the lever m and the eccentrics o the cover k can be pressed against
or withdrawn from packing on the side of the filtering apparatus.
The chambers c d e f are filled with wood wool, gravel or other suitable
filtering material.
In order to have a chamber containing fresh filtering material always ready
for use, the upper opening is closed by a plate the lower side remaining open,
so that water can pass through the filtering material in the lower chamber to
the pipe R.
When the chambers c d e f are to be filled or emptied, the nut of the screw_t
is loosened so that the lever m can be withdrawn and the cover k can be removed.
On removing the plate p the apparatus can be turned by hand half a revolution
round the axle a.
To prevent the chambers c d e f from turning automatically while the appa-
ratus is at work they have near the nave n on the outside rounded projections r.
one of which is always engaged between two corresponding projections s (Fig. 3)
on the tubular axle a.
In the modified apparatus shewn in Fig. 4 the water has a considerably longer
course through the filtering material.
The additional filtering chambers a through which the water has to pass are
separated from the discharge pipe R by perforated plates or wire gauzes 9¹ while
they are externally closed by sheet-metal slides pl
The apparatus shewn in Figs. 1 and 2 is worked as follows:
The pipe R to which is fixed the apparatus is under the water level of the
river, brook, pond or tank, the water of which is to be purified before use.

page_text: In the lower chambers the openings of the perforated plate or of the sieve g
being free, the water can enter the apparatus.
The impurities contained in the water are deposited in the filtering material
contained in the chambers c d e f .
The water purified in this manner is led off through the pipe R to the place
where it is to be stored or used.
In order to avoid any interruption in the working when the apparatus has to
be cleaned, or fresh filtering material has to be supplied, the upper chamber is
held in reserve charged with filtering material the plate p protecting it from a
premature use.
For bringing the reserve chamber into use the cover is loosened and, the
plate being removed, and the apparatus is turned one half round, so that the
chamber containing the fresh filtering material becomes immersed. The cover k
is then tightened, the filtering material is removed from the chamber which is
then uppermost and this chamber is charged again with fresh filtering material,
and is closed by the plate 7).
In the apparatus shewn in Fig. 4 the water has a longer course through the
chambers as indicated by the arrows. The plates in this case also protect the
filtering material from use while in reserve and the slides can be withdrawn to
open the chambers u for removing and replacing filtering materials.
In other respects the working of the apparatus shewn in Fig. 4 is the same
as that of the apparatus shewn in Figs. 1, 2 and 3.
Figs. 5 and 6 shew a modified construction wherein the filter-chambers c d e f
are secured to a hollow cylinder C, which has on the one side a trunnion z and
on the other side a pipe R. The trunnion is journalled in a bearing L and
the end of the pipe R is in a stuffing-box S.
The apparatus is rotated by worm-gear r The part of the filter chamber.
which is inoperative is shut off towards the other half which is active by one of
two covers secured to a common stem in such a manner, that they can be
moved by a pair of eccentrics y fixed to a common axis which can be turned
by means of a lever m.

Improvements in Filtering Apparatus.
We, CARL GEORG EMIL SALZBERGER, Civil Engineer, of Leerstrasse 8.
Burgsteinfurt, Westfalen, Germany, and CARL KAPPESSER, Merchant, of Leer-
strasse 21, Burgsteinfurt, Westfalen, Germany, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:
This invention relates to an apparatus by means of which water containing
mud and sand is purified the working of this apparatus baing continuous.
Referring to the drawings accompanying our Provisional Specification. Figs. 1
and 2 are respectively transverse and longitudinal sections and Fig. 3 is a plan
of apparatus according to our invention. Fig. 4 is a transverse section of modi-
fied apparatus in which the water has to take a longer course.
Fig. 5 is a longitudinal section and Fig. 6 a sectional plan of a modification.
As shown in Figs. 1 and 2 the conduit pipe R for leading purified water to
a well or reservoir is connected by a flange with a tubular axle a having two
or more lateral openings 1.

page_text: A nave n, round which are arranged two or more chambers c d e f, is fitted
to revolve on the axle a. The chambers are separated from a and covered
inside and outside by removable perforated plates or wire-gauze diaphragms g
and g¹.
One end of a has a cross piece h through which passes the reduced end of a
bolt which is secured to h. The bolt serves as support and guide to the boss
of the cover which can slide to and fro thereon; transversely through bolt i
passes a bolt on which pivots a lever m which is firmly connected to two eccen-
trics o.
By the movement of the lever m and the eccentrics o working in a recess
in the boss, the cover can be pressed against or withdrawn from packing 7 on
the side of the filtering apparatus.
The chambers c d e f are filled with wood wool, gravel or other suitable
filtering material.
In order to have a chamber containing fresh filtering material always ready
for use, the upper perforated plate g is is closed by a plate p, the plate g of the
lower chamber remaining open, so that water can pass through the filtering
material in the lower chamber to the pipe R.
When the chambers c d e f are to be filled or emptied, the nut of the screw t
is loosened so that the lever m can be withdrawn and the cover k can be removed.
On removing the plate the apparatus can be turned by hand half a revolution
round the axle a for bringing the upper chamber into action.
To prevent the chambers c d e f from turning automatically while the appa-
ratus is at work they have near the nave n on the outside rounded projections r,
one of which is always engaged between two corresponding projections s (Fig. 3)
on the tubular axle a.
In the modified apparatus shewn in Fig. 4 the water has a considerably longer
course through the filtering material.
The additional filtering chambers a through which the water has to pass are
separated from the discharge pipe R by perforated plates or wire gauzes g¹ while
they are externally closed by sheet metal slides pl
The apparatus shewn in Figs. 1 and 2 is worked as follows:
The pipe R to which is fixed the apparatus is under the water level of the
river, brook, pond or tank, the water of which is to be purified before use.
In the lower chambers the openings of the perforated plate or of the sieve
being free, the water can enter the apparatus.
The impurities contained in the water are deposited the filtering material
contained in the chambers c d e f.
The water purified in this manner is led off through the pipe R to the place
where it is to be stored or used.
In order to avoid any interruption in the working when the apparatus has to
be cleaned, or fresh filtering material has to be supplied, the upper chamber is
held in reserve charged with filtering material the plate p protecting it from a
premature use.
For bringing the reserve chamber into use the cover is loosened and, the
plate being removed, the apparatus is turned one half round, so that the
chamber containing the fresh filtering material becomes immersed. The cover k
is then tightened, the filtering material is removed from the chamber which is
then uppermost for which purpose the plate is slid out, and this chamber is
charged again with fresh filtering material, and is closed by the plate p.
In the apparatus shewn in Fig. 4 the water has a longer course through the
chambers as indicated by the arrows. The plates in this case also protect the
filtering material from use while in reserve and the slides can be withdrawn to
open the chambers for removing and replacing filtering materials.
In other respects the working of the apparatus shewn in Fig. 4 is the same
as that of the apparatus shewn in Figs. 1, 2 and 3.
Figs. 5 and 6 shew a modified construction wherein the filter-chambers c d e f
are secured to a hollow cylinder C, which has on the one side a trunnion z and

page_text: on the other side a pipe R. The trunnion z is journalled in a bearing L and
the end of the pipe R can turn in a stuffing-box $ on the discharge pipe.
The apparatus is rotated by worm-gear .
The two filter chambers are closed at their outer ends by perforated removeable
plates or covers gas before, and they communicate at their inner ends through
perforated plates with the cylinder C and discharge pipe R. Covers are
provided in cylinder C, connected together so as to slide on a stem w and between
these covers are two excentrics y carried by a transverse shafte which can be turned
by a lever m thereby causing the excentrics to press the upper cover against
the upper filter chamber and thereby close it against cylinder C, while at the
same time the lower cover is raised from the perforated plate g of the lower
filter chamber, so that water can flow through this into cylinder C and away
through pipe R.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. Filtering apparatus for removing sand, muddy constituents, and the like
from water, wherein two or more chambers, such as c d e f filled with filtering
materials are arranged round a hollow shaft a round which they can be rotated,
and with which they communicated through perforated or wire gauze plates or
sieves g the said chambers being so arranged that only one or more lower ones,
which are immersed in the water to be filtered allow of the passage of such
water through them into the hollow shaft, the upper chamber or chambers being
for the time closed at their outer ends against the entrance of water by slides
such as p, such slides being removed and the chambers turned on the hollow shaft
when it is desired to put the upper chamber or chambers into action and to supply
the lower ones with fresh filtering material, substantially as described.
2. In filtering apparatus such as is referred to in the first claim the combina-
tion with the central hollow shaft and filter chambers of a cover carried by
a bolt and actuated by a lever m and excentrics o, for opening or closing the
apparatus and for holding the filtering chambers in position, substantially as
described with reference to Figs. 1, 2 and 3 of the drawings.
3. A modified construction of the filtering apparatus referred to in the first
claim, wherein the filter chambers are secured to a hollow cylinder C supported
on the one side by a trunnion Z and on the other side by a stuffing box S on the
discharge pipe, covers being provided within the cylinder C and operated by
excentrics in such manner that the uppermost chamber is closed by the one
cover while the other cover is moved away from the lower chamber so as to
allow the water to pass through it, substantially as described with reference to
Figs. and 6 of the drawings.
