Improvements in Lubricating Apparatus.
RICHARD RILEY, of Arkwright Mills, Miller Street, Manchester, in the County of
Lancaster, Mechanical Engineer, THOMAS WINSTANLEY, of Arkwright Mills, Miller
Street, Manchester, in the County of Lancaster, Mechanical Engineer, do hereby
declare the nature of this invention to be as follows: -
This invention has for its object the keeping at a constant level the lubricants
in oil cups, and other vessels containing lubricants on engines, and other parts of
machinery.
Hithertofore as the lubricants are being used the oil cups gradually become
empty, and if not re-filled, damage is likely to ensue owing to the parts heating
or galling.
By our invention the lubricants are kept at one level, thus ensureing a constant
feed of the lubricant.
One method of obtaining our object consists of an inverted bottle with a cork
fitting into its neck. The outer end of this cork fits into a elbow pipe which leads
to the oil cup or other vessel requireing to be kept full. A hole through the cork
forms a means of cummunication between the inverted bottle, and the oil cup.
On the outside part of the cork which fits into the elbow pipe are a number of
suitable air passages that also lead into the bottle.
Another means of attaining our object consists of the same inverted bottle being
attached to the oil cup with a piece of tube suitably made so that the cork, and its
air passages are dispensed with.

Improvements in Lubricating Apparatus.
RICHARD RILEY, of Arkwright Mills, Miller Street, Manchester, in the County of
Lancaster, Mechanical Engineer, THOMAS WINSTANLEY, of Arkwright Mills, Miller
Street, Manchester, in the County of Lancaster, Mechanical Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:—
This invention has for its object the keeping at a constant level, the lubricants in
oil cups, and other vessels containing lubricants on engines, or other parts of

page_text: Heretofore as the lubricants are being used the oil cups gradually become
empty, and if not re-filled damage is likely to ensue owing to the parts
heating through running short of oil.
By our invention the lubricants are kept at one level thus keeping up a con-
stant feed of the lubricants.
In order that our invention may be fully explained, and clearly understood we
have appended two sheets of drawings to which reference will be made, in which
Fig. 1 is a sectional front elevation through an oil cup as used on gas, and oil
engines showing the tube, and inverted bottle in its place.
Fig. 2 is a sectional front elevation through an oil cup lid showing our invention
in its relative place on the oil cup.
Fig. 3 is a sectional plan through X-X 1 of Fig. 1.
Fig. 4 is a part sectional elevation showing our invention as fitted to a lubricator
giving a regular feed by a ratchet wheel and paul, only so much is shown as is
necessary to illustrate the application of our said invention.
In the said drawings, the same figures or letters of references indicate the same
parts in all the views.
:
Refering to Figs. 1, 2 and 4. A represents the oil cup in which it is desired
to keep the contents at a uniform level. B designates the inverted bottle or vessel
which may be preferably constructed of glass or other transparent material. This
bottle forms the oil resevoir, and is mounted above the cup A, it being connected
therewith by a tube C extending from the bottom outlet of the resevoir or bottle
downwards to the inside of the cup A the lower end of said tube terminating at a
determined point with relation to the constant and uniform level of the lubricant
which it is desired to maintain in the cup A. When B is filled, and fixed in
position the level of oil in A establishes itself in relation to the lower end of the
feed tube C which is on the same plane as it is desired the level of oil in A shall
be kept, as soon as the level of oil in A is reduced below the end of the feed tube C
a quantity of air rushes up the tube C and into the inverted bottle B displaceing
a quantity of oil sufficient to raise the level of oil in A to the lower end of tube C.
This operation being continous so long as any oil remains in bottle B, it will thus
be seen that a uniform constant level is maintained in the cup A.
In Fig. 1 we have shown a construction in which an elbow pipe is used as a
connection between the resevoir or bottle B and the oil cup A, instead of the
direct vertical tube as shown in Figs. 2 and 4. In this construction the bottom
horizontal arm 1) 1 is arranged with relation to the constant and uniform level of
the oil in A. The bottle B is mounted upon the end of the elbow pipe, and fitting
in B is the cork or tube C, in this form of our invention in addition to the feed
tube C having a central hole it also has air passages on the outside as shown at D
in Figs. 1 and 3. These air passages lead to the interior of the bottle B by way
of the central hole in C.
The way of working this construction is as soon as the level of oil in cup A and
elbow pipe D1 gets below the uniform level and lower end of tube C a quantity
of air rushes down the air passages D passes the under end of tube C and up the
central hole into the interior of B, thus displaceing a quantity of oil which runs
down C and establishes the uniform constant level of oil in A, and elbow pipe D 1.
The distinction between the two forms of construction illustrated is that the
direct tube form as shown in Figs. 2 and 4 is adapted for connection with the
caps of oil cups while the elbow pipe form as shown in Fig. 1, is adapted for con-
nection with the oil cups. i.
It will be understood that our invention is adapted for application to any of the
ordinary forms of oil cups or similar vessels in use.
A tap or cock E is provided in tube C as shown in Figs. 1, 2, and 4, which is
used to facilitate the operation of filling the bottle, and mounting it in position.
The level of oil in the inverted bottle or resevoir B will be always visible owing
to the transparent nature of such bottle, so that there is formed a sight feed of
the amount of oil in store.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
-
1. In a mechanism for maintaining a constant level of oil in oil cups and other
vessels, the combination with the cup, of a bottle or resevoir, mounted in position
at a point above the normal level, and connected with the cup with a tube pro-
jecting into the latter, and having its end terminating at a point relative to the
normal level which it is desired to maintain substantially as, and for the purpose
set forth.
2. In a mechanism for maintaining a constant level of oil in oil cups and other
vessels, the combination with the cup, of a bottle or resevoir, mounted in position
at a point above the normal level, and a feed tube extending from said bottle or
resevoir, and having its end terminating within the cup, and on the plane of the
normal level which it is desired to maintain, substantially as, and for the purpose
set forth.
3. In a mechanism for maintaining a constant level of oil in oil cups and other
vessels, the combination with the cup of a bottle or resevoir, mounted in position
at a point above the normal level, a feed tube extending from said bottle or
resevoir, and having its end terminating within the cup at a point relative to the
normal level which it is desired to maintain therein, and a cork or tube arranged
within said tube, and provided with a feed opening affording cummunication
between the resevoir, and the tube, and with exterior passages forming air vents
substantially as, and for the purpose set forth.
