PROVISIONAL SPECIFICATION.
Improvements in or relating to Lubricators.
I CHARLES ANKERS 22 Hospital Street Nantwich Cheshire Watchmaker do
bereby declare the nature of this invention to be as follows:-
My invention relates to lubricators or introducing oil and other liquid lubricants
to bearings, and is especially applicable to lubricators liable to be placed in
positions where they cannot be freely got at such as lubricators fitted to the
hubs, between two sets of spokes in velocipede wheels.
The object of my invention is primarily to facilitate the introduction of the
lubricant through the lubricator and my invention consists of a special form of
lid and method of and means for attaching the same to the body of the lubricator
as hereinafter more fully described.
The body of the lubricator is preferably cylindrical or cup-like form, and the
top or mouth therefore circular.
A
The lid is made secure to the body of the lubricator by means of a screw or
rivet passing through a hole near the edge or circumference, and, therefore
screwing or being rivetted to an extention of the wall of the cup or a piece of
metal securely fastened to the inside or outside; the side or wall of the cup.
circular, band, or straight spring is embedded in a groove cut round the outside of
cup near the top, or inserted in a groove up the side of cup, and forces one end of
the circular straight or other form of spring into a slot cut in the edge of the lid
therefore the lid is held firmly down on the top of the cup-when closed. The
lubricator may be readily opened or closed by operating the lid with one finger or
say the spout of an oil-can. The hole in the lid being near the edge therefore
when pushed from the spring sideways slides quite off the top of the cup, and
leaves it free for the lubricant to be inserted.

Improvements in or relating to Lubricators.
I, CHARLES ANKERS, of 22, Hospital Street, Nantwich, Cheshire, Watchmaker,
do hereby declare the nature of the said 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 oilcups or lubricators such as are used on the hubs of
cycle wheels and in similar positions. The position of such lubricators renders
them difficult of access, and the object of my invention is to so construct such
lubricators that they may be readily opened for the purpose of supplying oil,
whilst suitable provision is made for the exclusion of dust.
Lubricators according to this invention are cup shaped and provided with a
sliding lid which is swivelled on the lubricator. A spring suitably attached to the
lubricator engages with an indent or catch formed in or on the lid, and so locks
the lid in its closed position.

page_text: In the annexed drawings different forms of my invention are illustrated, the
figures of the drawings being drawn to an increased scale in order that the parts
may be more clearly shewn.
C
With reference to Figures 1 and 2 a denotes the lubricator, the lid thereof,
and the spring by which it is locked. It will be seen that the spring c is disposed
within a groove & which is cut in the circumference of the cup, and soldered at e
to the cup.
The free end of the spring e is turned upwardly so as to engage with
the indent in the lid when the latter is closed.
In Figures 3 and 4 the spring c is disposed within the cup a, being soldered to
the inner surface thereof at e, the action of the spring being identical with that
described with reference to Figures 1 and 2.
In Figures and 6 the spring c passes diametrically through the cup, and
derives its elasticity from its turned over end g which bears upon the outer surface
of the cup. In these figures the cup is shewn partially enclosed by a plate h, to
which the lid is swivelled by the screw k. In Figures 1 to 4 the lid is swivelled
on the wall of the cup, which in some cases may be thickened at this point.
The lid of the lubricator is provided with a projection m by which it may be
readily opened by the finger nail, or spout of an oil-can.
In Figures 7 and 8 the spring e is adapted to engage with a catch formed on
the lid. In this instance the pressure of the spring is outward instead of inward
as in the other figures.
Instead of being disposed circumferentially as shewn in Figures 1 to 4 and 7
and 8, or diametrically as in Figures 5 and 6, the spring e may be arranged
vertically upon the side of the cup, where the depth of the cup is sufficient to
afford sufficient length and elasticity to the spring.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is: :-
1. The combination in an oil-cup or lubricator, of a swivelled lid 6 provided
with an indent or catch f, and a spring e adapted to engage with such indent or
catch and lock the lid in its closed position, arranged substantially as herein set
forth.
2. The arrangement and combination in a lubricator, of a swivelled lid b
provided with an indent, and a spring e disposed in a groove cut in such
lubricator, substantially as shewn and described with reference to Figures 1 and 2
of the drawings hereto annexed.
3. The arrangement and combination in a lubricator, of a swivelled lid b
provided with an indent f, and a spring e disposed circumferentially within said
lubricator, substantially as shewn and described with reference to Figures 3 and 4
of the drawings hereto annexed.
4. The arrangement and combination in a lubricator, of a swivelled lid b
provided with an indent f, and a spring c disposed diametrically within said
lubricator and formed with a turned over end g, substantially as shewn and
described with reference to Figures 5 and 6 of the drawings hereto annexed.
5. The arrangement and combination in a lubricator, of a swivelled lid b
provided with a catch f, and a spring e, substantially as shewn and described with
reference to Figures 7 and 8 of the drawings hereto annexed.
