COMPLETE SPECIFICATION.
Improvements in Oil-cups and Lubricators suitable for Use in .
connection with Cycles, Engines, and General Machinery.
I, EDWARD WARWICK, of Sheffield Works, Alma Street, Aston, in the
County of Warwick, Manufacturer 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 in improvements in relation to receptacles technically
known as oil-cups and also technically known as lubricators, such as are used in
small sizes attached to the parts of cycles for lubricating the moving parts and
bearings and such as are used also in larger sizes over the journals of shafting and
in connection with other moving parts of engines and machinery.
Hitherto lubricators or oil-cups have been made for use on cycles, with removable
caps; the result of using such oil-cups or lubricators is that the cap gets lost and
the lubricator filled with dust instead of oil and in a like manner the movable caps
of the larger lubricators used on machinery when taken off are frequently
by accident or misadventure dropped into the moving machinery leading to
expensive breakages.
To remedy the defects in the old-style oil-cups or lubricators, I produce the oil-
cups or lubricators hereinafter described.
The nature, scope, and general features of my invention will be fully understood
from the following descriptive Specification taken in connection with the
accompanying drawings, in which

In carrying out the first modification of my invention see Figs. 1, 2, 4, 5, 6, 7,
8, 9, 10 and 11 I provide a flat metal blank of any required size, the configuration
of which would be such as to form into the required cup-shape; I next by suitable
tools dish the flat blank and afterwards by suitable press tools or other tools
convert the dished blank into a cup-shape such as that shewn at Figure 6; the cup
shewn at Figure 6 would next be further compressed into the cup form shewn at
Figure 9 a sectional elevation of which is shewn at Figure. 1. a represents the
upper square chamber and b represents the lower circular chamber; c represents
the outer passage through which the oil or other lubricant flows.
I provide a flat bar or stamping pierced with holes as shewn at Figure 5; I next
bend the flat bar or stamping into a yoke shape as shewn at Figure 8; the yoke d
is provided with a pivot-pin e and the yoke is connected to the square part of cup
by passing the pivot-pin through the lower part of yoke and through the oil-cup
as shewn in section at Figure 1; the pivot-pin can be brazed or otherwise secured
air-tight to the walls or sides of oil-cup.
I next provide a cover-plate fas shewn in detail at Figures 7 and 10 and as shewn
at f Figures 1, 2 and 3 ; I next provide a spiral spring 9 and place it in position
as shewn at Figure 1 and secure such spiral spring over the cover-plate by means
of the guiding-pin h, the guiding-pin secures the spiral spring between the
cover-plate and the roof of the yoke.
The 1st modification put together in the manner described and shewn by Figs. I
and 2 is by preference screwed at the lower end b ou the outer surface j. In using
the 1st modification so constructed the screwed lower end b would be rotated into a
tapped hole provided near the cycle bearing or journal or other moving parts of
machinery that required lubricating; oil, tallow, paraffin, or any other suitable
lubricating substance would then be put or poured into the chamber a from whence
it passes into and fills up the lower part b, the oil-cup or receptacle would thus be
filled from the outlet hole c to the lid f; the pressure of the spring g against the lid,
cover or plate would press the plate f firmly over the mouth of container or
lubricator; when the lubricating substance required removing the operator would
by means of the projecting edges k lift and move the lid finto the position shewn
in dotted lines at Figure 2 carrying the yoke d with the cover f, thus leaving the
mouth of the cup a uncovered or open as shewn at Figure 9 ready to receive the
lubricating substance; the cover fand its yoke would then be moved back into
the position shewn at Figure 1.
It will be readily understood from the foregoing description that the 1st modifi-
cation of my invention constitutes a practical oil-cup or lubricator by the use of
which the container can be filled in the night time or in the day time without the
risk of mislaying or losing the cover.
In carrying out the second modification of my invention in lieu of the spiral-
spring I provide a spring of the kind shewn at Figure 3; the second modification
is covered and uncovered in the manner herein before described in relation to the
first modification.
In carrying out the third modification of my invention the container is provided
with spherical recesses m and n. 1 provide a flat blank similar or equivalent to the blank
shewn at Figure 16 and then by suitable tools turn down the edges o so as to form
a flanged lid; I then turn down the arms p and q into the vertical position.shewn

page_text: at p and q Figure 18, the ends of the arms would be compressed by means of
suitable punches or tools so as to produce on the ends of the arms projecting
spheroidal knobs r and ; the two walls of the container would be chambered or
compressed between the convex holes n and m as shewn at t in broken section
Figure 19 and in broken elevation at Figure 20.
In using the cap and container of third modification the cap would be passed
over the container as shewn at Figure 12 with the spheroidal knobs and s passed
into the lower concave recesses m and in such position the cap would bear tightly
over the upper edge or face u of container, when the user desired to refill the
container he would lift the cap in an upward direction by means of the projecting
edges and thus move the spheroidal knobs r and s from the bottom recesses m along
the groove t into the upper recesses n so that the cap or cover could be
moved into the position shewn at Figure 13, the spheroidal knobs and s
turning in the upper recesses to radiate the cap into the position shewn in
dotted lines at Figure 13; it will be apparent that the cap could be removed
from the container and that it would not be so absolutely secured to the con-
tainer as
are the caps of the first and second modifications nevertheless the
pressure required to lift the cap of third modification need not be such as to
move the spheroidal knobs out of the guiding recess therefore the cap of third
modification is in a sense a fixture and not likely to be lost although by the
exertion of sufficient force the side arms p and q can be made to yield and the
cap removed.
In some cases I prefer to dispense with the guiding groove t
relying on the lip or flange v of the cap to guide and present the spheroidal
knobs into their axial bearings.
Although I have illustrated and described the upper portion of the containers
of first, second, and third modifications of my invention as of a rectangular
transverse section for the purpose of providing the most room, nevertheless in
some cases I prefer to make the containers of each modification of an oval,
round, or polygonal transverse section and it will be apparent that such change
of the transverse section of containers will not interfere with the action of the
radiating lids of the first and second modifications or of the lifting lids of the
third modification.
I am aware that prior to my invention metal oil cups and other cups of various
kinds have been raised from sheet metal blanks. I therefore make no claim to
this method of producing the cups or containers of the lubricators hereinbefore
described.
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 :-
1st. The combination of a lubricator container with a radially bung yoke carrying
a spring-adjusted lid to form and forming a removable lubricator as illustrated
and described in relation to the 1st modification.
2nd. The combination of a lubricator container with a radially hung yoke
carrying a lid adjusted by means of a bow spring to form and forming a removable
lubricator as illustrated and described in relation to the 2nd modification.
3rd. The combination of a lubricator container with a cap provided with arms
carrying spheroidal knobs taking into spheroidal concavities formed in the con-
tainer by means of which the cap can radiate on its arms to uncover the container
to form and forming a removable lubricator as illustrated and described in
relation to the 3rd modification.
