COMPLETE SPECIFICATION
Apparatus for Recovering Oils from Condensation Water by Filtration.
I, SEBASTIAN BENDER, of Allmendingen, near Ulm on the Danube, in the Empire
of Germany, Manufacturer, 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.-
The present invention relates to an improved apparatus for the recovery of
cylinder lubricating and other oils from the condensation water of steam engines,
the purpose of the invention being to produce a device that is automatic and only
in action when required
With these ends in view the invention consists in certain novel features of
construction and combinations of parts as will be more fully described herein-
after
Referring to the accompanying drawings, which form part of this specification,
Fig. 1 shows a vertical longitudinal section of my improved apparatus
Fig 2 is a plan view of same and
Fig. 3 18 a section on line A-B of Fig 2
The water mixed with the oil enters the box-like receptacle or trough b through
the admission tube a. Said receptacle b is fitted with inclined twigs or bristles c,
which serve as a filter for the water by preventing the passage of the oil, con-
tained in the water, which collects at the surface thereof
A rotating screw-like brush d or the like which is slightly immersed in the
water, absorbs the oil from the surface of the water and carrying it with it deposits
the oil particles during its rotation at an inclined channel which is fitted with
bustles, from which channel f it can easily be collected in a vessel or receptacle
placed under the mouth of same.
The water thus freed from the oil passes under the partition wall g fitted in
the vessel 6 and issues through the exit tube h
The partition wall g serves for the purpose of preventing the exit through the
tube of the oil collected at the surface of the water
The exit tube his fitted with a branch fitted with a cock from which
issues a portion of the water running through the tube h on to a rotating water
wheel m journaled in suitable bearings in a bracket fitted to the receptacle b,
said water wheel m being in connection with suitable power transmission
means, such for instance as pulleys no and an endless belt or rope p for the
purpose of imparting motion to the screw-like brush d previously referred to
The receptacle provided beneath the mouth of the exit tube h and beneath
the water wheel m serves for collecting the water, from whence it can be removed
by way of the branch r.
Instead of only employing a portion of the water running through the tube h
for the purpose of driving the water wheel m, the whole of same can be allowed
to issue on to the water wheel by a single tube.
The apparatus as hereinbefore described will only then automatically start its
action when condensation water passes through same, the screw-like brush &
requiring the passage of the water through the apparatus for its actuation.
Instead of the water wheel m a conveyer screw or a turbine may be employed.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1) An apparatus for the recovery of oil form condensation water by filtration,
characterised by arranging above the filter a rotating brush which receives the
oil collected at the surface of the water and delivers same into a channel fitted
with a wiping-off brush, the water being delivered on to a water wheel or the
like for actuating the rotary brush, substantially as described and shown
2) Apparatus for the recovery of oil from condensation water, the whole con-
structed arranged and adapted to operate substantially as described with reference
to the accompanying drawings.
