Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both

Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to that kind of small lubricators such as are more
particularly employed for bicycles and the like. In such lubricators, in addition to
a dust tight fastening, value is placed on its being possible to observe the condition
of the liquid from the outside. In order to cope with both requirements, the
following improved arrangement is adopted in the lubricator forming. the object
of the present invention :-
a
A metal frame or ring is screwed on the under part or base provided in the
ordinary manner with a screwed extension for screwing it on the wheel hub or
the like. The lower part of said metal is formed as a ring with an internal screw
thread for the above purpose and connected with the top plate by means of narrow
bars. In the top plate, an inlet opening is arranged capable of being closed by
A casing
spring valve in the ordinary manner customary in metal lubricators.
formed of celluloid or other suitable transparent or translucent material is placed
over the open sides or frame formed by the aforesaid narrow bars and firmly
attached by suitably bending over it the edge of the top plate. The interior of
the lubricator can thus be inspected through the apertures existing between the
bars and the condition of the lubricating fluid observed while a firm connection of
the upper part with the under part is established by means of the metal frame-
work and the use of a solid valve fastening is rendered possible.

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 that kind of small lubricators such as are more
particularly employed for bicycles and the like. In such lubricators, in addition
to a dust tight fastening, value is placed on its being possible to observe the
condition of the liquid from the outside. In order to cope with both requirements,
the following improved arrangement is adopted in the lubricator forming the
object of the present invention and shown in Figures 1-4 of the accompanying
drawings; in which,

A metal frame or ring b is screwed on the under part or base a provided in the
ordinary manner with a screwed extension for screwing it on the wheel hub or the
like. The lower part of said metal frame is formed as a ring b¹ with an, internal
screw thread for the purpose of screwing it to the base a and is connected with
the top plate 62 by means of narrow bars 63. In the top plate 62 an inlet
opening d is arranged capable of being closed by a spring valve in the ordinary
manner customary in metal lubricators. A casing c formed of celluloid or other
suitable transparent or translucent material is placed over the open sides or frame
formed by the aforesaid narrow bars 63 and firmly attached by suitably bending
over it the edge of the top plate. The interior of the lubricator can thus be
inspected through the apertures e existing between the bars 63 and the condition of
the lubricating fluid observed while a firm connection of the upper part with the
under part is established by means of the metal framework and the use of a solid
valve fastening is rendered possible.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is:
:-
A lubricator with a transparent casing (c) formed of celluloid or the like,
characterised by said transparent casing being connected with an under part or
base (a) by means of a supporting frame (61 62 63) provided with apertures (e),
substantially as heretofore described.
