I, ALBERT FREDERICK COLE, of Sutton Park Road, Kidderminster, in the County
of Worcester, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to the construction of lubricators for the lubrication of
cycles, vehicular machines, bearings, and shafting, and has for its object sim-
plicity, efficiency, and suitability for the purposes required.
The manner in which I carry out my invention I will now describe:-In the
first form of lubricator I construct a cylindrical cup (hereinafter called the oi!
cup) the rim thereof being turned outwards, the outside of the bottom of the oil
cup is made hexagonal and below is reduced in diameter and screwed, through
which is drilled or formed a passage communicating with the oil cup. The oil
cup has one, two, three, or more holes or perforations formed through the sides
thereof, and is also slit, cut, or slotted out downwards to the said holes or per-
forations. The whole of this part of the lubricator may be made in one piece,
or the oil cup may be made separately in the form of a tube perforated or slotted,
and soldered or otherwise fastened to the remaining described part. The hex-
agonal part may in some cases be made circular, and milled or roughened. Out-
side and over the oil cup I fit a cylindrical cap (hereinafter called the cap) the
top closed and projecting beyond the sides, and milled or roughened, the bottom
of the cap is turned inwards to the same extent as the top of the oil cup is turned
outwards. Its action is as follows.
The lower end of lubricator described is screwed in the bearing required to be
lubricated, the cap is drawn upwards disclosing the holes perforations or slots in
the sides of the oil cup through which the oil is injected and flows down the pas-
sage to bearing, the said cap being then pressed downwards closes the lubricator
and renders same dust proof. The slit above the holes or perforations in the oil
cup hereinbefore mentioned may be omitted. The cap may be perforated or may
be slit, or both perforated and slit instead of being formed on the oil cup.
In a modification of the first described form the cap may be inserted into the
perforated or slotted oil cup instead of on the outside as before described.
Pins, pegs, indentations or other equivalent means may be used instead of the
rims on either the cap or oil cup, or on both to prevent the cap being removed
from the oil cup. The rims, pins, pegs, and indentations aforesaid may be so
arranged to permit of the cap being removed by turning the same round to a
certain point.
In my second form of lubricator I construct a cylindrical cup (hereinafter called
the oil cup) the bottom of which is hexagonal, milled, or roughened, and below

reduced in diameter and screwed, through which is formed the passage to the oil
Into the said oil cup I fit a cylindrical cap (hereinafter called the cap)
the top end thereof closed, and projecting beyond the sides and milled or
roughened, the sides are perforated with one, two, or more perforations the upper
sides of the oil cup are inwardly indented, corresponding in position to the per-
forations in cap, or a pin or pegs may be inserted in oil cup which passes through
perforations in cap in such position that the cap may be raised to disclose the
perforations thereon for the purpose of oiling. The cap when pressed downwards
closes the lubricator and renders it dust proof.
Instead of the cap last described a cover may be made with two slotted arms
extending downwards which fit inside oil cup, a pin or pegs is inserted, through
the upper end of oil cup, and passing through the two slots in arms of cover (or
two corresponding indentations in oil cup would suffice for the pins or pegs)
the cover when raised its full height may be turned over after the manner of a
hinge, and when pressed down closes the lubricator. Instead of the slotted arms
on the cover aforesaid, two three or more grooved downwardly extending arms
may be used, the pins pegs, or indentations in oil cup fitting in said grooved
arms in such manner that the cover may be raised or lowered. Likewise two
three or more downwardly extending arms may be made Jor hooked shape in a
circular direction, the pins, pegs, or indentations, corresponding to same in like
manner described. The upper end of oil cup may be grooved or turned over and
the arms as last described hooked in such manner that when cover is raised the
said hooks shall engage with said groove or turned over portion of oil cup in
order that the coyer may be operated as herein before described.
a
My second form of lubricator and its modifications herein described may be
made vice versa, that is to say the cap or cover may be made to fit over or outside
the oil cup instead of in the manner hereinbefore described and the necessary
parts in conjunction therewith being reversed accordingly.
In some cases
wire or rod may be inserted through the lower part of lubricator thereby adding
to its utility the advantage of the well known needle lubricator" also the said
rod or wire may serve the purpose of a valve by being made conical, shouldered
or of greater diameter at the upper part of its length than the lower part. In
cases where applied to ball bearings the bottom end of wire or rod or valve is
made of sufficient length that the balls in moving in the ball race may tilt or
lift the said rod or wire or valve to pass the desired amount of oil, the said rod
or wire or valve may pass also through top of cap, or fastened to cap loosely to
permit of its due movement. The lubricator and its modifications hereinbefore
described as cylindrical with vertical sides, may be made partly or wholly
spherical, thereby making the oil retaining capacity of the lubricator greater.
The lubricator herein described although specially adapted for cycles and
vehicular purposes may with the hereindescribed modifications be used for the
lubrication of all kinds of bearings.

I, ALBERT FREDERICK COLE, of Sutton Park Road, Kidderminster, in the County
of Worcester, 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:-
This invention relates to the construction of lubricators for cycles and for

page_text: other machinery bearings, my object being to attain simplicity in manufacture
combined with suitability and efficiency for the purposes required.
In order that my invention and the carrying of the same into effect may be
the more readily understood I append hereunto a sheet of explanatory drawings
to be hereinafter referred to.
Figure 1, 2 and 3, represent one form of my improved lubricator, Figure 1
being an elevation of the cup or body part, Figure 2 a like view, but with part
in section, of the cap or upper part, and Figure 3 an elevation of the complete
lubricator.
Figure 4 represents another form of my lubricator, and Figures 5, 6, and 7 a
further modification, Figures 5 and 6 representing the cap or upper part alone
and Figure 7 the complete lubricator.
The same reference letters in the different views indicate the same or similar
parts.
In the construction of a lubricator of the form illustrated by Figures 1, 2,
and 3, I employ a cylindrical cup as A, having an outwardly turned rim or
projection as A¹ at its upper end. The lower end of the cup is made of a suitable
form for attachment to a cycle wheel hub or other required part. The cylin-
drical body of the cup or oil receiver is provided with lateral apertures as A² to
readily admit the spout of an ordinary oil can, and the metal above each aper-
ture is preferably slit through longitudinally as at A³.
Over the lubricator cup or oil receiver hereinbefore described, I fit telescopi-
cally the sliding cap B having its upper end closed, and its lower and open end
provided. with an inwardly turned projection as B₁ corresponding with the out-
wardly turned projection or flange A' of the cup A. When the cap B is pressed
down over the cup A the perforations as A in the said cup are closed or covered
to exclude dust and dirt from the exterior of the lubricator. But on drawing
up the cap B to its full extent, as illustrated in the view of the complete lubri-
cator at Figure 3, the apertures are uncovered to permit of the introduction of
lubricant to the bearing.
In the form of my lubricator illustrated at Figure 4, the cap B is made to
slide telescopically within the cup A instead of over the same as in the form
shown at Figures 1, 2 and 3, the complete withdrawal of the cap from the cup
being prevented by projecting stop pegs as B2 from the cap which abut against
the upper ends of the side apertures through the cup. I sometimes employ such
stop pegs, or snugs, indentations, and other equivalent means of preventing the
complete withdrawal of the one part from the other, in the construction of
lubricators of the form or type illustrated by Figures 1, 2, and 3, instead of the
end flanges or projections shown in such figures.
Instead of making the oil admission apertures in the body or cup or receiver
part A of the lubricator as hereinbefore described, I sometimes employ a cap or
cover as B Figures 5, 6, and 7, provided with two or more slotted arms such as
shown, which slide inside the oil cup. Stop pegs, snugs, or indentations, enter
the slotted arms and thus prevent complete withdrawal.
I sometimes insert a short length of wire within the lubricator such as is
employed with the well known needle lubricators, the wire being made to serve
as a valve if desired by the provision of a shoulder thereon.
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. In lubricators for cycles and for other machinery bearings, the combination
comprising an oil cup or receiver as A provided with lateral apertures and a
closing cap as B sliding telescopically within or over the part A, substantially as
described and as illustrated at Figures 1, 2, 3, and 4 of the drawings.
2. In lubricators for cycles and for other machinery bearings, the combination
with an oil cup or receiver as A of a cover as B having perforated arms sliding

and 7 of the drawings.
