Improvements in Lubricating Pins or Spindles or like Devices
as applied to Wheels or other like Parts of Machinery.
I, WILLIAM JOHN BREWER, care of Charles Mason Esq., C.E.. of
10 Lyndhurst Square, London S.E. Civil Engineer, do hereby declare the nature
of this invention to be as follows:-
The object of my invention is to provide an improved lubricating pin or spindle
to be applied to the wheels or the like or other parts of various kinds of machinery,
which is also applicable to other like purposes.
In carrying out my said invention, I form that part of the pin or spindle, which
carries the wheel or like part of machinery hollow; and provide same with a cup
or box for containing the lubricant; said cup or box to be kept normally closed by
a spring.
This hollow spindle is adapted to feed the oil or lubricant necessary for the
proper lubrication of the working parts. As an alternative the outside end of the
said pin may be bent up and provided with a suitable cover for excluding dust,
grit or other substance or matter.
The hollow pin or spindle will be provided with a hole or holes in its wall,
communicating with a hole or passage in the bush or nave of the wheel. This hole
or passage communicates in turn with a hollow chamber surrounding the nave or
bush of the wheel, and is adapted to contain the oil or other lubricant that flows
into it through the passage in the hollow pin or spindle.
The action of the improved lubricator is as follows:-
The flap closing the end of the hollow pin or spindle being lifted up, cotton waste
or other suitable material is then placed in the hollow pin or spindle and the oil or
other lubricant introduced, or the cotton waste may first be thoroughly saturated
with the lubricant and then placed in the hollow pin or spindle. Upon the wheel
or other like part of the machinery being revolved around the pin or spindle, the
oil or like lubricant, flows into the hollow chamber which is provided in the nave
or bush of the wheel and vice-versa, thus constantly lubricating the wearing or
bearing parts in its course and so prevent heating or seizing of the parts.
It will be seen that by this method the thorough and constant lubrication of all
the parts are effected and the lubricating material is protected from dust, grit or
dirt and when the spindle is once filled with oil or the like, will not need attention
for some time.
Dated this 9th day of September 1891.

Improvements in Lubricating Pins or Spindles or like Devices
as applied to Wheels or other like Parts of Machinery.
1, WILLIAM JOHN BREWER, care of Charles Mason Esq., C.E., of
10 Lyndhurst Square, London S.E., Civil Engineer, 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 object of my invention is to provide an improved lubricating pin or spindle
to be applied to wheels of various kinds of machinery, also applicable to other like
purposes.
And in order that my invention may be the better understood I now proceed to

page_text: describe the same, reference being had to the drawing hereunto annexed and to
the figures and letters marked thereon.
Figure 1 is a sectional elevation through my lubricating pin and through the
boss of a wheel thereon.
To carry out my said invention I form hollow, like a tube, the pin or spindle A,
which forms the journal for the wheel B, or like part of machinery, and I screw or
permanently fix the said hollow pin or journal rigidly in the horn plates C or other
framing supporting the journal. The wheel B is adapted to freely revolve thereon,
and is conveniently provided with an internal bush D of gun metal or other
material.
At the outer end of the hollow pin or journal A i provide a cup or box E for
containing lubricant, communicating by a lower passage F with the interior of the
hollow pin ur journal. Alternatively the outer end of the hollow pin or journal A
may be turned up to form the said box for the lubricant. The said box E is
preferably closed by a spring pressed lid F" to exclude dust or dirt.
The interior of the hollow pin or journal A communicates with a suitable hole or
holes K to the outside bearing face of the journal, and I provide a hollow chamber G
in the boss of the wheel, communicating also with the bearing face of the journal,
which is adapted to contain the lubricant or oil that flows into it from the box E,
and through the hollow pin or journal A, and the passages therefrom, K.
I fill the lower part of the box E, and the end of the passage in A, with cotton
waste H, or other suitable material, to form a filter for the oil or lubricant as it
passes to the bearing, and the oil or lubricant is then poured or filled into the box E;
or the cotton waste may be first saturated with oil or lubricant before being placed
in position.
Upon the wheel or other like part of the machinery being revolved around the
pin or spindle, the oil or lubricant flows into the hollow pin or journal A and thence
through the holes K to the bearing and the external chambers G and thus keeps
the bearing constantly lubricated so as to prevent heating or seizing, and this
without waste of oil or lubricant.
It is obvious that where space is limited the lubricating box may be made much
flatter against the boss of the wheel.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. An improved lubricating rigid pin or journal with a hollow interior,
communicating at one end with an oil or lubricating box, and by a hole or holes
through the pin to the bearing face of the journal, substantially as described.
2nd. The combination of a hollow pin or journal with an oil or lubricating box
fitted at the end of said pin, and provided with a strainer of cotton waste or other
suitable material around and in the passage of communication, between the oil or
lubricant in the box and the said hollow spindle, substantially as described.
3rd. The combination with a wheel or other revolving article provided with an
oil chamber in its boss of a hollow fixed pin or journal adapted to receive lubricant
into its interior and to distribute the same to the bearing faces, and to the said oil
chamber in the wheel, substantially as described.
4th. The combination and arrangement of parts of a revolving boss and an
