Improvements in Cycle and like Lubricatore.
I, HARRY LUCAS, Managing Director, of the Firm of Joseph Lucas Limited,
of "Tom Bowling" Lamp Works, Little King Street, in the City of Birmingham,
Manufacturers, do hereby declare the nature of this invention to be as follows:-
-
This invention consists of improvements in lubricators for cycles, motor cars,
and for other machine bearings, my object being to construct dust proof lubricators
of a neat and simple form that can he readily and conveniently charged with the
oil or other lubricating material.
In the production of lubricators in accordance with my invention I preferably
make the metallic body part of a circular shape with the exception of its lower
end, adjacent to the screwed stem, which is made of a hexagonal or other con-
venient shape for the application of a spanner for fixing the lubricator in position
upon the required part.
Instead of making the internal aperture, for the reception of the lubricant,
concentric with the lubricator body, I preferably bore such aperture eccentric
with the said body and through the thicker portion of the metal at one side
of such aperture I cut a slot for the reception of the hinge pin lug formed
with or attached to the underside of the lubricator cap. The said cap is pre-
ferably of a flat disc like form and is provided with a lip on the side opposite
to the hinge pin lug for greater convenience in opening.
The hinge pin of the lid or cap is secured in the metal of the lubricator body,
and the hinge pin lug itself is so formed that on the opening of the lid a small
spiral spring, placed in a recess below the hinge pin, is depressed; but on the
closing of the cap the action of the said spiral spring upon the suitably shaped
hinge pin lug causes the cap or lid to be pressed tightly into contact with the
top of the lubricator for the purpose of excluding dust.
The small aperture to convey the lubricant from the interior of the lubrica-
tor through the stem to the required bearing, is preferably made concentric with
the complete lubricator body and its screwed stem.

page_text: Manufacturers, 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 consists of improvements in lubricators for cycles, motor cars,
and for other machine bearings, my object being to construct dust proof lubricators
of a neat and simple form that can be readily and conveniently charged with the
oil or other lubricating material.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to:―
Figure 1 is an elevation with part in section, representing, to an enlarged
scale, a cycle lubricator constructed in accordance with my invention, the hinged
lid being shown open.
Figure 2 is a similar view to Figure 1 but with the lid closed.
Figure 3 is a sectional plan of the lubricator body on the line 1, 2, Figure 2.
The same reference letters in the different views indicate the same parts.
In the production of lubricators in accordance with my invention I preferably
make the metallic body part A of a circular shape with the exception of its lower
end A', adjacent to the screwed stem, which is made of a hexagonal or other con-
venient shape for the application of a spanner for fixing the lubricator in position
upon the required part.
Instead of making the internal aperture A2, for the reception of the lubricant,
concentric with the lubricator body, I preferably bore such aperture eccentric
with the said body and through the thicker portion of the metal at one side
of such aperture I cut a slot a for the reception of the hinge pin lug b formed
with or attached to the underside of the lubricator cap B. The said cap B is pre-
ferably of a flat dise like form and is provided with a lip on the side opposite
to the hinge pin lug for greater convenience in opening.
The hinge pin C of the lid or cap is secured in the aperture c formed through
the metal of the lubricator body, and the hinge pin lug is so formed that on
the opening of the lid a small spiral spring 1 placed in a recess below the
hinge pin, is depressed and retains the lid in its open position; but on the
forcible closing of the cap the action of the said spiral spring upon another
part of the hinge pin lug 6, as shown, causes the cap or lid to be pressed tightly
into contact with the top of the lubricator for the purpose of excluding dust
A plunger E is interposed between the lug and the spring D as illustrated.
The small aperture A to convey the lubricant from the interior of the lubrica-
tor through the stem to the required bearing, is preferably made concentric with
the complete lubricator body and its screwed stemi.
Having now particularly described 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 cycle and like lubricators, the combination with a hinged lid or cover
of a spring disposed within one side of the body of the lubricator and serving
to retain the lid both in its open and closed position, substantially as described
and as illustrated.
2. Improved eyele and like lubricators constructed substantially as described
and as illustrated.
