PROVISIONAL SPECIFICATION.
Improvements in or connected with the Automatic Lubrication of
Revolving Shafts.
I, GERALD HENRY BRETON, of 6 Cambrian Terrace, Beeston Hill, Leeds, in
the County of York, Mill Manager, do hereby declare the nature of this invention
to be as follows:-
This invention has reference to an apparatus-specially arranged for horizontal
shafts that pumps up the oil, over and over again, and thus keeps the journals
constantly lubricated whenever the shaft is revolving; and which further filters the
oil during its passage round the apparatus.
The object of the invention is to save oil and that by the introduction of an
apparatus the simplicity of which precludes anything getting out of order.
I accomplish niy object as follows:-Parallel with the horizontal shaft to be
lubricated I arrange an horizontal screwed spindle working in a suitable horizontal
cylinder, or tube, down which the oil is drawn or forced by the revolutions of the
screw on the said spindle. The mouth of the horizontal cylinder projects into a
reservoir of oil, and the screwed spindle is arranged so as to be easily withdrawn
for cleaning purposes by the removal of a gland. At the tail of the horizontal
cylinder is fitted a removable plug so that the whole may be cleaned out in a few
seconds. The mouth of the tube is arranged some little distance above the bottom
of the reservoir-so-that only the better oil is re-pumped. A suitable pipe leads
the pumped oil to the top of the main shaft. The horizontal screwed spindle,
which is provided with a speed-cone, is revolved by a belt or cord actuated by the
main horizontal shaft. After the oil has been pumped up and passed over the
journal it is collected and led through suitable channels down to the filtering box
placed immediately above the main reservoir, into which latter it drops after filtera-
tion. The reservoir forms the base of the apparatus and has the pump &c.
attached to it, the said reservoir being in its turn fixed to any convenient part of
the structure supporting the main shaft. The thread of the revolving screw should
be square on its periphery and it should fit the cylinder completely, though not
tightly. Open or crossed belts, as required, may be used to revolve the screw in
the requisite direction.
One pump may be arranged to serve several adjacent journals, the oil being piped
back to the main filter and reservoir.

I, GERALD HENRY BRETON, of 6 Cambrian Terrace, Beeston Hill, Leeds, in
the County of York, Mill Manager, 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 :-

oil during its passage round the apparatus.
The object of the invention is to save oil, and that by the introduction of an
apparatus, the simplicity of which precludes anything getting out of order.
In order to fully explain my invention 1 have annexed a drawing in which
Fig. 1 shows the essential parts and à general arrangement of my apparatus, for
an horizontal shaft, in sectional elevation; whilst
Fig. 2 is a more compact arrangement suitable for use in positions where neigh-
bouring pulleys on the main shaft make it desirable to save space.
A is the main shaft, B the bearing to be lubricated, and C the base of any
hanger, frame, or block, on which the bearing may happen to be resting.
1 accomplish my object as follows:-Parallel with A, the shaft to be lubricated,
arrange a screwed spindle D, working in a suitable cylinder or tube E, down which
the oil drawn or forced from the reservoir, F, by the revolutions of the screw
on the said spindle. The mouth of the cylinder projects into a reservoir of oil F, and
the screwed spindle is arranged so as to be easily withdrawn for cleaning purposes
by the removal of a gland G. At the tail of the horizontal cylinder is fitted a
removable plug H, so that the whole may be cleaned out in a few seconds. The
mouth of the tube is arranged some little distance above the bottom of the reservoir,
as shown in the drawing, so that the better oil only is re-pumped.
In addition to this I preferably fill the lower portion of the reservoir with water,
as metallic and such like sediment deposits itself better therein the water however
must not reach the screw.. A. suitable pipe J leads the pumped oil to the upper
side of the main shaft,, as shown. The screwed spindle-which is provided with a
speed cone K-is revolved by a belt or cord actuated by the main shaft and the
end-thrust is taken-by-a-collar K. After the oil has been pumped up and passed
over the journal it is collected and led down through suitable channels M, M, to
the filtering box N, placed immediately above the main reservoir, into which latter
the oil drops after filtration.
The filtering box, as shown, consists of a frame arranged to carry as many
perforated plates and layers of wire-mesh as the circumstances of the case demand;
two such filtering-layers, O¹ and 02, are shown in Fig. 1; whilst three, 0, 0, 0³,
are shown in Fig. 2; the lower filtering layer should-be-arranged so that the oil
does not drop immediately over the screw. By this arrangement the filter may be
easily and rapidly cleaned at convenient times. In Fig. 2, the reservoir forms the
base of the apparatus and has the pump, etc., attached to it; the said reservoir
being in its turn fixed to any convenient part of the structure supporting the main
shaft. The thread of the revolving screw should be square on its periphery, and it
should fit the cylinder completely, though not tightly. An open, or crossed belt,
as required, may be used to revolve the screw in the requisite direction-
dependent on the cutting of the screw, which may be either a right or left hand
thread.
One pump may be arranged to serve several adjacent journals the oil being piped
back to the main filter and reservoir. Both in Figs. 1 and 2 an intermediate
plate, I, is introduced in the drawing between the base C and the fixing-piece of
the apparatus; this is only useful so far as it allows greater play in fixing, but as
an endless variety of circumstances have to be met; this, and the mode of
driving by belt, allow great scope in erecting the apparatus. A drainage plug Q
may be fitted at the foot of the reservoir as shown, or at the side.
The apparatus may of course be fixed on the ground when required.
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. The self-contained automatic lubricating pump, oil filter, and reservoir,
arranged, constructed, and operated, substantially as described, with the object set
forth.

page_text: 2. The combination of a reservoir of oil, a revolving screw pump, and a filtering
box, all self-contained, substantially as described and shown, with the object and
for the purpose set forth.
3. In a lubricating apparatus, the combination of a screwed rod, arranged in a
line parallel with the shaft to be lubricated, so as to allow of its being driven by
belting, the said rod passing through and revolving in an oil reservoir, having an
upper frame fitted up as a filter, substantially as described and shown, with the
objects set forth.
