PROVISIONAL SPECIFICATION.
Apparatus for the Purification of Lubricating and other Oil.
I, JOSEPH DEUSS, Manufacturer, of Gladbach, Germany, do hereby declare the
nature of this invention to be as follows:-
My invention has for its principal object to purifiy the oil that has been used
for the lubrication of machinery, so that the same can be used again.
The apparatus chiefly comprises an oil receptacle, in which is placed a second
oil receptacle containing in its lower part a filter. The latter is closed at the top
and at the bottom with a straining plate, and communicates at the bottom with
the main receptacle, in such a manner that, if the outer receptacle is filled with
oil, it enters the filter from the bottom and rises to the upper part of the inner
receptacle, from which it may be discharged laterally through a radial pipe
provided with a cock. The cover of the inner receptacle communicates with the
atmosphere through a thin air pipe, and the mud that collects at the bottom of the
outer receptacle may be discharged through a cock.
The two straining plates which enclose the filtering material are mounted on a
vertical spindle, the upper plate being kept at a given distance from the lid by a
sleeve, while the lower plate is adjustable in height, and therefore the filter com-
pressible, by turning the screw spindle, and a helical spring which surrounds the
same between the two straining plates.

COMPLETE SPECIFICATION.
Apparatus for the Purification of Lubricating and other Oil.
I, JOSEPH DEUSS, Manufacturer, of Gladbach, Germany, 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 :-
My invention has for its principal object, to purify the oil which has been used for
the lubrication of machinery, in order that the same may be employed again.
The apparatus chiefly comprises an oil receptacle, a in which placed a second oil
receptacle e containing in its lower part a filter b. The latter is closed at the top and
at the bottom with a straining plate, and communicates at the bottom with the main
receptacle a, in such a manner, that, if the receptacle a is filled with oil, the latter
enters the filter from the bottom and rises through the same to the upper part of the
receptacle c, from which it may be discharged in a clarified condition through a radial
pipe provided with a cock d. The cover of the inner receptacle communicates with
the atmosphere through a thin air-pipe g, and the bottom part i of the receptacle a is
provided with a cock f for letting off the mud which accumulates in the same.
The two straining plates which enclose the filtering material, preferably cotton and
sawdust, are mounted on a vertical spindle k; the upper plate is kept at a given
distance from the lid by a sleeve or hollow stay k¹, while the lower plate is adjustable
in height, and therefore the filter compressible, by means of a screw nut m and a
helical spring which surrounds the spindle k between the two straining plates.
Having now particularly described the nature of my invention and in what
manner the same may be performed, I declare that I claim :-
:-
Apparatus for the purification of lubricating and other oil, comprising in its con-
struction a main vessel or receptacle (a) and an inner receptacle (c) enclosed in the

page_text: main vessel and provided at the bottom with a filter b, the filter being rendered
adjustable in depth by means of a niovable straining plate or sieve bottom, and the
apparatus provided with an air pipe (9), a discharge cock (d) for the purified oil, and
a mud cock (f), substantially as described.
