WILLIAM NEWBOLD BAINES, of the Millgate Brass Works, Rotherham, in the
County of York, Brassfounder. "IMPROVEMENTS IN SELF-ACTING OR AUTOMATIC
STEAM LUBRICATORS, IMPERMEATORS, OR GREASERS." [A communication from
abroad by Eberhard de Limon, of Dusseldorf, Germany, Engineer.]
These improvements consist in constructing self-acting or automatic steam
lubricators, impermeators, or greasers, which work on the principle of displacement,
with a separate way or ways for the entrance of the steam for condensation into the
body of the lubricator, over and above or independent of the passage or passages
through which the lubricating material trickles on its way to grease the steam, the
final end or ends of said independent way or ways delivering the condensed steam
below the lubricant. Thus on the one hand the flow of steam into the body of the
lubricator does not interfere with the passage of the lubricant outwards; nor on the
other hand does the latter choke the entrance of the steam inwards; and not only do
both these hindrances arise in lubricators as ordinarily constructed, but they are
subject to the further disadvantage of frequently delivering only condensed water
instead of a lubricant, owing to the steam for condensation being admitted above
the lubricating material.
Further, as it is essentially necessary for the efficient working of automatic lubri-
cators to secure a proper condensation of the steam within them to cause displace-

steam way or ways already mentioned, partly within and partly without the body
of the lubricator.
DESCRIPTION OF THE LUBRICATOR.
The body of the lubricator is constructed in the form of an oblong hollow cylinder,
and made either of brass, gun metal, iron, or other suitable material, and of such
diameter and length, as to give the capacity necessary to contain such measure of
oil or other lubricating material as may be determined upon, the cylinder standing
upright on a shank terminating either in a screw or flange for the purpose of fixing
it to the steam pipe or valve chest to be lubricated; the shank has two holes
passing upwards, and is fitted with a stop-cock, the plug of which has also two holes
or passages through it to correspond with those in the shank, one passage leading
directly into a stand pipe within the cylinder, through which stand pipe the lubri-
cant is emitted; while the second passage lends the steam for condensation into
a hole passing up the side of the cylinder, either inside or outside, to a pipe arched
over, and outside the top of the cylinder, and descending on the other side, passes
into the cylinder nearly to its bottom there discharges the condensed steam under
the lubricant, and as the latter floats upon the former, it is gradually emitted down
the internal stand pipe as the condensed water accumulates in the body of the
cylinder.
The cylinder at the top is fitted with a cock through which it is charged with
lubricating material, the action of the apparatus being controlled, and the emission
of lubricating material regulated and adjusted by means of the bottom cock fitted
in the shank.

WILLIAM NEWBOLD BAINES, of the Millgate Brass Works, Rotherham, in the
County of York, Brassfounder. "IMPROVEMENTS IN SELF-ACTING OR AUTOMATIC
STEAM LUBRICATORS, IMPERMEATORS, OR GREASERS." A communication from
abroad by Eberhard de Limon, of Dusseldorf, Germany, Engineer.
The nature of the said Invention for improvements in self-acting or automatic
steam lubricators, impermeators, or greasers, to be as follows:-
These improvements consist in constructing self-acting or automatic steam lubri-
cators, impermeators, or greasers, which work on the principle of displacement, with
a separate way or ways for the entrance of the steam for condensation into the
body of the lubricator, over and above or independent of the passage or passages
through which the lubricating material trickles on its way to grease the steam, the
final end or ends of said independent way or ways delivering the condensed steam
below the lubricant; thus on the one hand, the flow of steam into the body of the
lubricator does not interfere with the passage of the lubricant outwards, nor on the
other hand does the latter choke the entrance of the steam inwards; and not only
do both these hindrances arise in lubricators as ordinarily constructed, but they
are subject to the further disadvantage of frequently delivering only condensed water
instead of a lubricant, owing to the steam for condensation being admitted above
the lubricating material.
Further, as it is essentially necessary for the efficient working of automatic lubri
cators to secure a proper condensation of steam within them to cause displacement
of the lubricant, an additional improvement consists in making the separate steam
way or ways already mentioned, partly within and partly without the body of the
lubricator, which is constructed in the form of an oblong hollow cylinder, and made
either of brass, gun metal, iron, or other suitable material, and of such diameter and
length as to give the capacity necessary to contain such measure of oil or other
lubricating material as may be determined upon, the cylinder standing upright on a
shank terminating either in a screw or flange for the purpose of fixing it to the
steam pipe or valve chest to be lubricated; the shank has two holes passing upwards
and is fitted with a stop-cock, the plug of which has also two holes or passages
through it to correspond with those in the shank, one passage leading directly into
a stand pipe within the cylinder, through which stand pipe the lubricant is emitted,
while the second passage leads the steam for condensation into a hole passing up
the side of the cylinder either inside or outside to a pipe arched over and outside
the top of the cylinder, and descending on the other side passes into the cylinder
nearly to its bottom, there discharges the condensed steam under the lubricant, and
as the latter floats upon the former it is gradually emitted down the internal stand
pipe as the condensed water accumulates in the body of the cylinder.
The cylinder at the top is fitted with a cock through which it is charged with
lubricating material, the action of the apparatus being controlled, and the emission of
lubricating material regulated and adjusted by means of the bottom cock fitted in
the shank, while for the purpose of discharging the condensed water out of the
apparatus, preparatory to supplying it with fresh lubricating material, there is a
screw valve or cock placed at the foot of the cylinder, having its internal entrance
slightly raised above the bottom, so that the whole of the condensed water shall not
be drained off, but sufficient is always left behind to cover the discharging mouth
of the condensed steam passage, and thus prevent any lubricant choking it by
finding an entrance therein.
And in order that my said Invention may be more fully understood and readily
carried into effect, I will now proceed to describe the Sheet of Drawings hereunto
annexed, in which the same letters are used to denote similar parts in each Drawing
or illustration.

page_text: Figure 1 is a front elevation; Figures 2 & 3 are sectional elevations at right
angles to each other, Figure 4 being a plan or cross section across line 2, 2, see
Figure 2; while Figure 5 is an end view of the shank, showing the two passages
inwards, and the whole are drawn half size of a lubricator having the capacity to
hold two gills, or half a pint of lubricating material.
A, A, is the body of the lubricator; B, B, the charging cock at top, its entrance
being guarded from dust by a revolving slot cover; Č, Č, the cock in the shank,
with its two passages; d, d, the internal stand pipe; F, E, the passage for steam
and condensed steam; F, the screw valve for discharging the condensed water.
Having thus particularly described and ascertained the nature of my said Invention,
and the manner of carrying the same into effect, I would have it understood that
I do not confine myself to the precise details above set forth, as the same may be
varied without departing from the principle of my Invention, but I would have it
understood that what I do claim as my Invention and desire to secure by the
herein-before in part recited Letters Patent is, the arrangement of a clear and
distinct passage or passages for the admission of the steam and condensed steam or
water, perfectly independent of the passage or passages for the emission of the
lubricant, which steam or water passage or passages may be wholly within or
wholly without, or, as is preferred, partly within and partly without the body of
the apparatus.
In witness whereof, I, the said William Newbold Baines, have hereunto set
my hand and seal, this Fifteenth day of June, in the year of our Lord
One thousand eight hundred and seventy-eight.
