An Improved Method and Apparatus for Filtering Spent or other
Oils.
THOMAS TURNER Engineer 34 Northcote Road Preston Lancashire 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
An apparatus which comprises a cistern with a slanting bottom, fig. 1, on drawing.
A coiled pipe fig. 1. A fixed to bottom of cistern for heating the oil. A dish
containing two sieves, fig. 2, placed on top side of cistern, the cistern contains one
or more horizontal filtering chambers fig. 3. The cistern is fixed on top of receiver
fig. 4, there is one or more funnels with a long outlet pipe fig. 5 which as one or
more fine sieves fig. 6, attached to the said long outlet pipe, the said long outlet pipe
and sieves are inserted in one or more vertical chamber or chambers, fig. 7, which is
attached to receiver fig. 4. The vertical chamber or chambers as an outlet, fig. 8,
fixed near the top which conveys the oil to the spout of receiver, fig. 9. A Tap is
fixed to cistern fig. 1, near slanting bottom to draw of dirty oil or water.
A Tap
is also fixed at bottom of receiver, fig. 4, to draw of clean oil which is ready
for use.
The method of working the above mentioned is as follow, empty the spent or other
oils into the dish containing two sieves, fig. 2, placed on top side of cistern, the said
two sieves as cotton waste placed between them, the oil will work through sieves and
clean cotton waste into the cistern, fig. 1, repeat this until the oil covers the horizontal
filtering chambers, fig. 3, apply steam to the coil pipe, fig. 1. A, to heat the oil to
100 or 120 degrs. of heat the oil will then work itself through the horizontal filtering
chambers which is filled with clean cotton waste and drop into a funnel or funnels,
fig. 5, down the long outlet pipe containing one or more fine sieves, fig. 6, which is
inserted in the above mentioned vertical chamber or chambers fig. 7. The vertical
chamber or chambers contains clean water or other liquid the funnel conveys oil down
through the water and liberates the said oil near the bottom the oil then rises upwards
through the water or other liquid and passes through the fine sieves from under side,
the said fine sieves to the outlet fig. 8, then to spout, fig. 9, attached to receiver the
said spent or other oil is then ready for use.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same as to be preformed I declare that what I
claim is as follow
1st. I claim as features of novelty the horizontal filtering chambers.
2nd. Also an apparatus 5. 6. 7. 8 on drawing.
3rd. Method of conveying spent or other oil downwards through clean water or
other liquid and filtering it upwards through clean water or other liquid and sieving
the spent or other oils from bottom side of sieves upwards.
