COMPLETE SPECIFICATION.
Improvements in or connected with Lubricators for Velocipedes.
1, JAMES DALE Junior, of 73, Pimlico Road, Pimlico London, Gentleman,
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 :-
My invention relates to improvements in or connected with lubricators for
velocipedes, the object being to produce a dust-proof lubricator that will not
require to be touched or handled in any way when being fed with oil, but which
can be opened, when required, by the simple pressure of the nozzle of the oil can,
while it instantly and automatically closes itself when the pressure is removed, and
can be readily taken to pieces for cleaning purposes.
My improved lubricator consists of a hollow cylindrical or other suitably
shaped body, furnished with a screw threaded stem or extension by means of
which it is screwed into the required part of the velocipede, the said body being
surmounted by a cap or lid which may either screw or spring on to same and which
is provided with a central hole or perforation, normally closed by a small plug or
stopper which is retained in position by the pressure of a suitable spring beneath
it, so that upon the nozzle of the oil can being pressed upon the top of the said
plug or stopper, it is forced down disclosing the opening which allows oil to pass
into the body of the lubricator and from thence to the bearings of the
velocipede.
In order that my invention may be more fully understood, I will now proceed
to describe same with reference to the accompanying drawings in which
Fig. 1 is a side elevation of my improved lubricator and
Figs. 2, 3, 4 and 5 side elevations with the cases in section, of four different
forms or arrangements of same.
Like letters of reference indicate corresponding parts throughout the views.
As shown in Fig. 1 my improved lubricator consists of a hollow cylindrical
body provided with a screw threaded extension e and furnished with a cap or
lid "", the said cap or lid being furnished with a central hole or perforation which
is closed by a small plug or stopper a retained in position by a spiral spring s as
shown in Fig. 2.
The lubricator shown in Fig. 3 is of similar construction to that shown in Figs. 1
and 2 with the exception that the plug or stopper is retained in place by
a flat
spring s, one end of which is soldered or rivetted to the body of the lubricator,
while the free end bears against the underside of the plug or stopper.
Fig. 4 shows a slightly modified form of lubricator in which the spring s is of
different shape to that shown in Fig. 3, while the plug or stopper a instead of being
free within the hole or perioration is hinged at one side to the cap e as shown at l,
and Fig. 5 shows a lubricator furnished with a hinged plug or stopper in com-
bination with a spiral spring, and I may in either form or arrangement add a
trap (Fig. 3) consisting of a piece of wire gauze or net work of the shape of a
hemisphere which is placed over the opening at bottom of lubricator as shown, and
which when moistened with oil will retain any particles of dust or the like which
may enter the lubricator, and prevent them from passing into the bearings of the
machine.

page_text: 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 velocipedes the formation of a hole or perforation in a cap
or lid such as c for admittance of the oil, and the closing of same by a plug or
stopper a retained in position by means of a suitably arranged spring, substantially
as herein described and shown and for the purposes specified.
2. The improvements in or connected with lubricators for velocipedes substantially
as herein described and shown and for the purposes specified.
Dated this 3rd day of September 1895.
