PROVISIONAL SPECIFICATION.
Improvements in Lubricators.
1, JAMES BALDWIN of Devonshire Brass Works, Keighley, in the County
of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
My improved lubricator I make as a "sight feed" lubricator to be connected
to a chamber containing oil, or to be used directly upon the point to be lubri-
cated, or to be fixed in a series of two or more placed on a box or connected
together by branches.
On the bottom end of the sight feed I fix a screwed valve for regulating the
inflow of oil which can be either forced in by a pump or by pressure of steam
against the oil. I then take a pipe just entering into a round chamber, the oil
rising through this pipe and passing in sight of a circular glass fixed in the front
of the chamber, and which is kept tight by a washer and screwed gland. On
the top end of this chamber there is a projection which is fitted with a screwed
plug for the purpose of cleaning the inside of the chamber or for filling it with
water.
The delivery of oil passes down a small tube which reaches to the top of the
projection mentioned above, the tube passing down through the body where the
screwed valve and inlet are placed and then out through a union to any desired
place where the lubrication is required. My improved sight feed can be made
with the outlet coming from the top end with a screwed valve on same this method
dispensing with the internal feed tube.
Or the sight feed can be used in series each sight being connected to a box or
connected together by branches, the delivery pipe being led from the sight feed to
the various points to be lubricated, thus avoiding subjecting the sight feeds to great
heat. One or more of the sights can be made to supply oil to bearings so that the
quantity of oil delivered can be seen passing through the sight feed in a similar
manner to that passing into the steam chest or cylinder.
My improved sight feed lubricator dispenses with the glass tubes at present
generally used, and which are so liable to get broken giving in their place a flat
surface of glass, made in any suitable shape, through which the quantity of oil being
used can be seen.

COMPLETE SPECIFICATION.
Improvements in Lubricators.
I, JAMES BALDWIN, of Devonshire Brass Works, Keighley, in the County
of Yorkshire, Engineer, 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:
-

a chamber containing oil, or to be used directly upon the point to be lubricated, or
to be fixed in a series of two or more placed on a box or connected together by

top end of this chamber there is a projection which is fitted with a screwed plug
for the purpose of cleaning the inside of the chamber, or for filling it with water.
The delivery of oil passes down a small tube which reaches to the top of the
projection mentioned above, the tube passing down through the body where the
screwed valve and inlet are placed and then out through a union to any desired
place where the lubrication is required. My improved sight feed can be made
with the outlet coming from the top end with a screwed valve on same this method
dispensing with the internal feed tube. Or the sight feed can be used in series each
sight being connected to a box or connected together by branches, the delivery pipe
being led from the sight feed to the various points to be lubricated, thus avoiding
subjecting the sight feeds to great heat. One or more of the sights can be made to
supply oil to bearings so that the quantity of oil delivered can be seen passing
through the sight feed in a similar manner to that passing into the steam chest or
cylinder.
My improved sight feed lubricator dispenses with the glass tubes at present
generally used, and which are so liable to get broken, giving in their place a flat
surface of glass made in any suitable shape through which the quantity of oil being
used can be seen.
In the drawings annexed hereto
Fig. 1 shows a part sectional view of my improved lubricator, the oil being forced
in, by means of a force pump, at J., the quantity being regulated by valve A. The
oil passes up pipe B. and into chamber C. being then visible through glass D., the
glass being held tight by means of the washer E. & screwed gland F. At the top
there is a screwed valve H. for closing the outlet, the oil when the lubricator is
working, passing through pipe I. to any desired point. The screwed plug G. is for
cleaning the interior.
Fig. 2 shows a front view of Fig. 1.
Fig. 3 shows the sight D. in front as in Fig. 2 but attached to an oil chamber L.
with a condenser M., this form being used when the oil is forced into the desired
parts by the pressure of steam; the quantity of oil passing being regulated by the
valve A. and passing in sight at the back of the glass D.
Having now particularly described & ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved sight feed lubricator substantially as described and shown in
drawings.
2. In a sight feed lubricator a glass disc, held tight, the oil passing through a
chamber and being visible through the glass disc.
3. The method of regulating the supply and stopping the outlet substantially as
described and shown in drawings.
4. The use of such a sight feed lubricator in connection with an oil chamber and
condenser as described and shown in drawings.
5. The use of such a lubricator as described either singly or in series, the oil
being forced through by a force pump.
