PROVISIONAL SPECIFICATION.
Improvements in Lubricators.
I, CHARLES CHEERS WAKEFIELD, of 51, Russian Drive, Stoneycroft, near
Liverpool, in the County of Lancaster, Manager, do hereby declare the nature of
this invention to be as follows:-
This invention relates to lubricators, the prominent features of the invention
being the arrangement of the parts whereby they can be easily taken to pieces for
renewal or repair, and the arrangement for adjusting or regulating the flow of
lubricant from the cup..
In carrying the invention into effect, I propose to form the top, sides and bottom
of the oil chamber of separate pieces, the sides being preferably of glass or metal
in annular form with joint rings at the top and bottom thereof. The bottom is
provided with a tubular nozzle for the discharge of the oil, and with an upwardly
projecting tubular stem adapted to screw into the top of the oil chamber. By
screwing this stem, therefore, into the top, a tight joint is made between the sides
of the oil chamber and the top and bottom thereof. The top aforesaid of the
chamber is threaded on the outside, and on to this is screwed a lock nut, also a cap
or cover provided with a downwardly projecting valve stem or plug which passes
through the tubular stem of the bottom. The raising or lowering of this valve stem
opens or closes a valve near the point of the nozzle, whereby the drip of the oil to
the bearing can be regulated. The oil flows from the oil chamber into the nozzle
through a hole in the tubular stem. An orifice is provided at the top of the
lubricator for filling the chamber with oil. It must be understood that the oil
chamber can be made in one piece, if desired, instead of making it in the manner
above set forth.
To adjust the drip or feed of the oil, the lock nut is unscrewed, and the cap with
the valve stem is screwed up or down to open or close the valve. When adjusted
to admit of the required feed, the cover, together with its valve stem, is locked in
position by the lock nut.
In some lubricators, it is desirable to have a window or lantern whereby the feed
or drip of the oil is rendered visible. This I accomplish by having a chamber with
transparent sides surrounding the point of the nozzle.
This chamber can be
constructed with openings in the sides, and a short glass tube inserted behind these
openings. By screwing the chamber on to or over the nozzle, with joint rings at
top and bottom of the tube, tight joints are secured and any possible leak prevented.
The drip or feed of the oil is rendered visible through the glass tube.
construction can, if desired, be adopted for the oil chamber.

COMPLETE SPECIFICATION.
Improvements in Lubricators.
I, CHARLES CHEERS WAKEFIELD, of 51 Russian Drive, Stoneycroft, near
Liverpool, in the County of Lancaster, Manager, do hereby declare the nature of
this invention and in what mauner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The invention relates to lubricators, the prominent features of the invention

page_text: being the arrangement of the parts whereby they can be easily taken to pieces for
renewal or repair, and the arrangement for adjusting or regulating the flow of
lubricant from the cup.
In order that the invention may be the more easily understood, reference will be
made to the accompanying drawing, in which-
Figure 1 is a sectional elevation of the lubricator.
Figure 2 is a section across the line aa of Figure 1.
In carrying the invention into effect, I propose to form the top A, the sides B
and the bottom C of the oil chamber of separate pieces, the sides being preferably
of glass or metal in annular form with joint rings a at the top and bottom thereof.
The bottom is provided with a tubular nozzle D for the discharge of the oil, and
with an upwardly projecting tubular stem E adapted to screw into the top of the
oil chamber. By screwing this stem E, therefore, into the top A, a tight joint is
made between the sides of the oil chamber and the top and bottom thereof. The
top of the chamber A is threaded on the outside, and on to this is screwed a lock
nut b, also a cap or cover F provided with a downwardly projecting valve stem or
plug G which passes through the tubular stem aforesaid E of the bottom. The
raising or lowering of this valve stem G opens or closes a valve near the point of
the nozzle, whereby the drip of the oil to the bearing can be regulated. The oil
flows from the oil chamber into the nozzle through a hole in the tubular stem.
An orifice d is provided at the top of the lubricator for filling the chamber with
oil. It must be understood that the oil chamber can be made in one piece, if
desired, instead of making it in the manner above set forth.
C
To adjust the drip or feed of the oil, the lock nut is unscrewed, and the cap F
with the valve stem G is screwed up or down to open or close the valve. When
adjusted to admit of the required feed, the cover F together with its valve stem G
is locked in position by the lock mit b.
In some lubricators, it is desirable to have a window or lantern whereby the feed
or drip of the oil is rendered visible. This I accomplish by having a chamber H
with transparent sides surrounding the point of the nozzle. This chamber H can
be constructed with openings in the sides, and a short glass tube K inserted behind
these openings. By screwing the chamber on to or over the nozzle, with joint
rings e el at top and bottom of the tube, tight joints are secured and any possible
leak prevented. The drip or feed of the oil is rendered visible through the glass
tube. This construction can, if desired, be adopted for the oil chamber.
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-
The general arrangement and construction of lubricators substantially as above
described whereby the feed can be exactly regulated and, if desirable, the quantity
of lubricant remaining in the lubricator and also the amount of drip can be seen at
any moment.
