An Improved Lubricator or Oil Cup for Velocipede Bearings and
other Bearings and Revolving Parts.
I, FREDERICK CHARLES WHITE, of 35, 36 and 37, Cow Lane, Coventry, in the
County of Warwick, Watch Manufacturers' Manager, do hereby declare the nature of
this invention to be as follows:-
This invention consists of the hereindescribed improved lubricator or oil cup for
the bearings of velocipedes and other bearings and revolving parts. My improved
lubricator or oil cup is so arranged that it is dust proof and the cap or cover
cannot become detached from the cup and get lost as is the case with somo other
Hubricators.
In carrying out my invention I provide an oil cup adapted to be screwed or
otherwise fixed to the hub of the wheel or bearing which is required to be
lubricated. This cup is provided with a cap which is made with a cylindrical
part fitting in the cup and adapted to slide up and down in the cup and in this
cylindrical part there is a side hole for pouring the oil into the oil cup. Fixed
to the centre of the said cup there is a tubular stem which passes down through
the oil hole in the bottom of the cup and around this tubular part there is a spiral
spring which presses the cap upwardly and keeps the cap raised whilst the oil is
being poured into the cup. In order to prevent the cap from rising too far, the said
tubular stem is made with an enlarged collar at its lower end which takes against a
shoulder in the central hole in the cup. In the said tubular stem there is a side hole
through which the oil runs to the bearing. The said cylindrical part of the cup has
a small projecting side peg at one part which will pass down a slot in the inner wall
of the cup and enter an annular groove running round the same so as to keep the
cap down when the lubricator is closed. To raise the cap for putting oil in the
lubricator the cap which is made with a milled edge has to be turned until its said
side peg matches the vertical slot in the cup when the spring will cause the cap to
rise and expose the said hole in the cylindrical part so that the oil can then be poured
into the cup. To close the lubricator the cap of the oil cup has to be pressed down
until its side pin enters the vertical slot in the wall of the lubricator cup and then the
cap is turned through a small angle so that the pin will catch under the groove in
the cup and thus the cap will be secured making the lubricator or oil cup dust
proof.
Instead of making the centro stem tubular as above described, the centre stem may
be solid and made rather smaller than the hole in the lubricator cup so as to allow the
oil to pass to the bearing.
In a modification of my invention instead of arranging for the coiled spring to
force the cap upwardly as above described, the said spring is arranged to draw the
cap down into its closed position. In this case the said slot in the inner wall of the cup
must be continued far enough down the cup to allow of the cap closing, and the
said peg
will be arranged near the bottom of the cylindrical part of the cap to take
on to the top of the cup or engage in the annular groove round the top of the cup to
keep the cap in its raised or open position against the pressure of the spring whilst
the cup is being filled; then by turning the cap to such a position that the said side
peg matches the vertical slot in the inner wall of the cup the spring will draw down
the cap and close the lubricator.

page_text: In a further modification of my invention the said side peg, slot and annular groove
round the top of the cup are dispensed with and in this case the cap has to
be held raised by the thumb and finger whilst the oil is being poured into the
lubricator.

An Improved Lubricator or Oil Cup for Velocipede Bearings and
other Bearings and Revolving Parts.
I, FREDERICK CHARLES WHITE, of 35, 36 and 37, Cow Lane, Coventry, in the
County of Warwick, Watch Manufacturers' Manager, do hereby declare the nature
of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement :-
This invention consists of the horeindescribed improved lubricator or oil cup for
the bearings of velocipedes and other bearings and revolving parts. My improved
lubricator or oil cup is so arranged that it is dust proof and the cap or cover cannot
become detached from the cup and get lost as is the case with some other
lubricators.
I will describe my invention by referring to the accompanying drawing on
which
Fig. 1 is a side elevation and Fig. 2 is a sectional elevation of a lubricator
constructed according to this invention; the lubricator is shewn closed in Fig. 1 and
open to receive the oil in Fig. 2;
Fig. 3 is a plan of the cup part separately;
Fig. 4 is a part sectional elevation and an inverted plan of the cap and central stem
part of the said lubricator separately;
Fig. 5 shews a modified form of the stem and
Figs. 6 and 7 illustrate a modification of my invention as hereinafter fully
described.
The same letters of reference indicate the saine parts in all the figures of the
drawing.
Referring firstly more particularly to Figs. 1, 2, 3 and 4, in carrying out this
invention I provide an open top oil cup A with an outlet hole a at the bottom and
adapted to be screwed or otherwise fixed to the hub of the wheel or bearing which is
required to be lubricated. This cup A is provided with a cap B which is made with
a cylindrical part & fitting in the top of the cup A and adapted to slide up and down
in the same and in this cylindrical part there is a hole for pouring oil in the
oil cup A. Fixed to the centre of the cap B there is a tubular stem D which passes
through the oil hole a' in the bottom of the cup A and around this tubular stem D
there is a spiral spring E within the cup A which presses the cap B upwardly and
keeps the cap B raised as in Fig. 2 whilst the oil is being poured into the cup through
the hole C. In order to prevent the cap B from rising too far the tubular stem D is
made with an enlarged collar d' at its lower end which takes against a shoulder a of
the cup A. In the tubular stem D there is a side hole 2 through which the oil passes
to the bearing. The cylindrical part of the cap B has a small projecting side peg f
at one part which will pass down a slot a3 and in the inner wall of the cup and enter
an annular groove g running round the same so as to keep the cap down when the
lubricator is closed. The said groove g may if desired be cut in a spiral or inclined
form, as shewn for instance by dotted lines in Fig. 7, so as the better to keep the cap
alose down on to the top of the cup when the peg f becomes worn,

page_text: To raise the cap B to expose the hole C for putting oil in the lubricator, the
cap B which is made with a milled edge has to be turned until its side peg f
matches the vertical slot a³ in the cup A when the spring E will cause the cap B to
rise and expose the hole C in the cylindrical part 6' so that oil can then he poured into
the cup A. To close the lubricator the cap B has to be pressed down until its side
pin enters the vertical slot a³ and then the cap B is turned through a small angle so
that the pin will catch under the groove g and thus the cap will be secured making
the lubricator or oil cup dust proof.
Instead of making the centre stem B tubular as above described the centre stem D
may as shewn for instance by Fig. 5 be made solid and rather smaller than the part
of the hole a' in the lubricator cup so as to allow the oil to pass through the hole a¹
to the bearing. This can be accomplished by cutting away one or more parts of the
stem D at d as in Fig. 4.
In a modification of my invention instead of arranging for the coiled spring E
to be in compression and force the cap B upwardly as above described, the said
spring E is arranged to be in tension and to draw the cap B down into its closed
position. In this case one end of the spring E has to be fixed to the bottom of the
cup A and the other end to the inside of the top of the cap B and the slot a³ is
continued far enough down the interior of the cup A as shewn in Fig. 7 to allow of
the cap B closing, and the peg / will be arranged as shewn in Fig. 6 near the bottom
of the cylindrical part of the cap B to take on to the top of the cup A or to engage
in the annular groove g round the top of the cup to keep the cap B in its raised or
open position against the pull of the internal spring E whilst the cup is being filled.
By turning the cap B to such a position that the said peg f matches the vertical
slot a in the inner wall of the cup A the spring E will draw down the cap B and close
the lubricator.
In a further modification of my invention the said side peg fand slot a³ and
annular groove g may be dispensed with and in this case the cap which is normally
pulled down to its closed position by the spring E has to be held raised by the thumb
and finger whilst the oil is being poured through the hole C to the lubricator.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with a lubricator cup of a cap made with a cylindrical part
fitting in and adapted to slide within the cup, an internal central stem fixed to said
cap and entering the oil hole of the cup and shaped to prevent the cap from rising
too high, a coiled spring within the cup adapted to raise the cap, a side filling
hole in the cylindrical part of the cap which is only exposed when the cap is raised,
and a side peg on the cylindrical part of the cap adapted to enter a slot and engage
in an internal annular groove near the top of the cup to secure the cap closed against
the pressure of the spring, all substantially as herein set forth.
2. The combination with a lubrication cup of a cap made with a cylindrical part
fitting in and adapted to slide within the cup, an internal central stem fixed to said
cap and entering the oil hole in the cup, a coiled spring within the cup fixed thereto
and to the cap adapted to close the same on to the cup, a side filling hole in the
cylindrical part of the cap which is only exposed when the cap is raised, and a side
peg on the cylindrical part of the cap adapted to enter a slot and engage in an
internal annular groove near the top of the cup to keep the cap raised against the pull
of the spring, all substantially as herein set forth.
3. The combination with a lubricator cup of a cap made with a cylindrical part
fitting in and adapted to slide within the cup said cylindrical part having a side
filling bole which is only exposed when the cap is raised, an internal central stem
fixed to said cup and entering the oil hole in the cup and a coiled spring within the
fixed thereto and to the cap and adapted to close the same on to the cup, all
substantially as hereiubefore set forth.
