" IN LUBRICATORS OR VISIBLE SUPPLY IMPERMEATORS
Year: 1885

page_text: We, JOHN STEVEN and THOMAS BURT, of 32 Elliot Street, Glasgow, Lanarkshire,
Brassfounders, do hereby declare the nature of our invention for IMPROVEMENTS
"
IN LUBRICATORS OR VISIBLE SUPPLY IMPERMEATORS," to be as follows:-
This invention has reference to an improved construction or general arrangement,
of visible supply lubricators or impermeators for conducting the oil or lubricant
in small beads or drops at regulated speeds with the steam to lubricate the internal
working parts and surfaces of steam engines, and which will be more convenient,
compact, self-contained, and portable than those heretofore in usc.
The improved construction of this lubricator consists as follows:-In mounting
the whole by a simple screw stem with jointing collar and polygonal head or neck
for screwing into a hole in the steam pipe chest or other part of the engine to
which it is to be applied. This screw stem has formed on it connected by a short
neck, the vessel containing the oil or lubricant in a liquid state, and which is
preferably of a vertical cylindrical shape, having a continuation of the throat tube
right up through it and as high above it, where it has formed at the front top end
a short screwed socket for the upper end of the short glass sight tube, right over a
corresponding screwed socket for the lower end of glass tube formed in the front
top end of the vessel. The socket at top is bored right up through for the
insertion and removal of the glass tube, and is screwed for the screwing-in stem
of a small clearing blow-off tap, and through which the glass can be filled with
water. In the front top side of the vessel a small circular valve chamber is
formed, with a small outlet valve seat at the inner end for the emission of the oil
from the top of the vessel, regulated by a conical valve formed on the inner end of
a screw spindle, passed out through a screw stuffing box in the screw socket tapped
and screwed into the outer end of this escaping valve chamber. The valve spindle
has a milled head or hand wheel outside for regulating the feed escape of the oil to
the chamber, from which it is led up through a small hole and nozzle screwed into
the socket at the lower end of the glass tube. The oil flows up through the
condensed water in the glass tube in beads, the speed of which is thus visible and
can be regulated as stated, until they reach the top socket where they enter
angular descending hole into the small straight hole bored right down to the neck
and pass into the steam chest. At the front lower part of the oil vessel, a screw

small

page_text: socket is also fitted with escape screw valve for occasionally blowing through and
draining and cleaning this vessel. The lower part of the stem screwed into the
steam chest for carrying the whole, is bored with a wide hole up to near the
bottom of the vessel, to admit the steam freely to a lateral screw socket, into which
is screwed a coupling knee branch projecting up just at the back of the oil vessel.
To this coupling knee a tube is jointed two feet or so high, formed with a quick
return bend at top, continued down and jointed by a coupling to the upper end of
a screw stem valve chamber screwed into the top of the oil vessel (behind the glass
or oil ascending and brass descending tubes) and having a small tube led down to
near the bottom of the oil vessel, the valve chamber having a small hole leading
down from the return steam tube through from the inside of the lateral valve seat
in the centre, and another hole leading down from the outside of the seat into said
tube. This valve seat chamber has a central controlling valve spindle and screw
stuffing-box socket screwed into it, with a milled hand wheel as on the front of the
vessel, and is for setting on or stopping the action of the lubricator. The lubricator
or working vessel may be filled with the oil or lubricant by a small conical filler in
top at the one side fitted with a small screw valve. All the valves are shut while
so filling the vessel with oil, and when these are first opened with only the steam
present acting with the same pressure above and below, the lubricator would not
work; but in a very short time the steam condenses in the return or second steam
tube with valve, and fills it with water and also the bottom of the lubricating
vessel taking the place of the oil which floats on it up to the discharge outlet
valve, as it is used. The working starts as soon as the tall condensing tube
leading to the bottom of the oil vessel fills with water, by the extra pressure
exerted on the water below the oil, due to the head pressure of water (as say from
6 to 18 inches) greater in that tube than in the glass tube above the oil on until it
expresses all the oil out in small globules through the glass and down the central
tube into the steam chest where it impermeates the steam and is carried on with it
to lubricate all the working surface with which the steam comes in contact, while
the whole instrument and its valves and fittings being all easy of access and yet
compact self contained and portable, rendering it a most convenient lubricator for
manipulation and efficient usefulness.

page_text: Improvements in Lubricators or Visible Supply Impermeators.
We, JOHN STEVEN, and THOMAS BURT, both of 32 Elliott Street Glasgow,
Lanarkshire, Brassfounders, do hereby declare the nature of our invention, and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement in writing reference being had to the
accompanying Sheet of Drawings and to the reference letters and figures marked
thereon, that is to say :-.
Our said invention has reference to an improved construction or general
arrangement and combination of the parts of visible supply lubricators, or
impermeators for conducting the oil or lubricant in small beads or drops at
regulated speeds with the steam to lubricate the internal working parts and
surfaces of steam engines, and which will be more convenient, compact, self-
contained, and portable than those heretofore in use.
In order that the full nature and novelty of our said invention, and the manner
of putting the same into effect or practice, may be properly understood we shall
now proceed to describe the several figures on the Sheet of Drawings which we
have hereunto appended for that purpose, the same letters indicating the same or
like parts in the several figures.
Figure 1 is a sectional elevation of a visible supply lubricator constructed in
accordance with our improvements; Figure 2 is an elevation of this improved
lubricator with a few of the parts shown in section which are slightly modified
from that shown in figure 1. And Figure 3 is a sectional elevation of the said
lubricator constructed in accordance with our improvements, but with several of
the parts somewhat modified from those shown in figures 1 and 2.
Referring to figure 1 our improved lubricator consists as follows:-in mounting
the whole by a simple screw stein A, with jointing collar and polygonal head and a
neck A for screwing it into a screwed hole in the steam pipe, chest or other part
of the engine, to which it is to be applied, either direct or with an intervening stop
cock as is well understood. This screw stem A has formed on it, or it might be
connected to it by a short screwed neck at A', the vessel B containing the oil or
lubricant in a liquid state, and which is preferably of a vertical cylindrical or other
ordinary outward shape, having a continuation of the throat tube a right up through
and as high above it, as to have formed at the top end on one side the upper
screwed socket C for the short glass sight tube Cright over the lower corre-
sponding screwed socket C of this glass tube, formed on the top end B' of the
vessel B. The top socket C is bored right up through the top for the insertion and
removal of the glass tube C¹, and screwed for screwing-in the stem of a small
clearing blow-off tap or screw valve at C³, and through which the glass C can be
filled with water as desired. In the front or near top side of the vessel at B' a
small valve chamber is formed, with a small outlet valve seat c open at inner end
to the top of the oil vessel B, for the emission of the oil therefrom, regulated by the
conical pointed screw valve c' passed out laterally through a screw stuffing box
screwed into the outer end of the escaping valve chamber c. The valve spindle c¹
has a milled head or hand wheel c² outside for regulating the feed escape of the oil
--

page_text: to the chamber c from which it is led up through the small tube nozzle c³ screwed
into the lower socket C2 of the glass tube C¹. The oil flows up through the
condensed steam or water in the glass tube C¹in beads to the top socket Č, at a
degree or speed regulated as stated, and from which the oil passes off by a small
angular descending hole at a¹ into the small straight tube hole a bored right down
to the neck A¹ of the stem A, cither through a stop cock or valve fitted to this or
direct into the steam chest or other part of the engine to be lubricated. At the
lower part of the oil vessel B on one side a screw socket is formed, to which a screw
valve. B² is fitted for occasionally draining off and blowing through and cleaning
this vessel. To the lower wide part of the stem A a coupling knee branch D is.
fitted, projecting up close to one side of the oil vessel B. To this coupling knee D,
à tube D¹ is jointed a foot or two high, formed with a quick return bend D' at top
or it might be a small water box D³, with a corresponding return tube D¹¹ continued
down and jointed by a coupling Du to the upper end of a small valve chamber d, d³,
screwed by its stem into the top of the oil vessel B, and having a small tube d
led down to very near the bottom of this vessel. This valve chamber d, d, has a
small hole led down from the return steam tube D", laterally through into the
valve seat d, and chamber d', in the centre, and thence by the hole d² on the
outside of the seat down into the tube d. This valve seat chamber d, d¹, has a
central controlling valve spindle d³ and screw stuffing-box socket d' screwed into
it, with a milled hand wheel on its outer end; and by which the lubricator is set
into or out of action. The lubricating or working vessel B would be filled with
the oil or lubricant as required by a small conical filler formed on a small screw
valve chest G, with hand wheel, screwed into the top B¹ of the vessel or close
thereto at one side as shown in Figures 2 and 3. All the valves would be shut
while so filling the vessel with oil, and when these are first opened with only the
steam present acting through the tubes D and a, with the same pressure above and
below the oil in the vessel B, the lubricator would not work. But in a very short
time the steam condenses in the return steam tube D2, D" or the little chest D³
above this, and fills it, and also the bottom of the lubricating vessel B, with the
water of condensation, the oil floating on it up to the top, is discharged out through
the valve c, c¹ at top of vessel direct as it is used, with a pressure due to the column
of water in the tube D". The working of the lubricator starts as soon as the tall
condensing tube D¹¹, d¹¹, leading to the bottom of the oil vessel fills with water, by
the extra pressure exerted on the water below the oil, due to the head pressure of
water (as say from 10 to 18 inches) greater in this tube D", than in the glass
tube C above the oil and goes on until it expresses all the oil out in small globules
through the valve c and glass C¹ down the central tube a into the steain chest,
where it impermeates the steam and is carried on with it to lubricate all the
working surface with which the steam comes in contact; while the whole instru-
ment and its valves and fittings are all easy of access, compact, self contained, and
portable, rendering it a most convenient lubricator for manipulation and efficient
usefulness.
Figure 1 A shows a section of the stem A, A¹, for supporting the lubricator and
its fittings all portable the same as in figure 1, but formed in a separate piece from
the lubricating vessel B, which is secured to it so as to be removable, by a screwed
socket and neck at A¹. A cock with hollow key K is fitted through the stem A in
a line with the knee branch D of the tube D¹ leading the steam up to the condensed
water supply tube D1 above the lubricator. This cock K, thus puts the lubricator
off or on, by shutting or opening the steam to the tube D, D', and the oil passage a
from the lubricator; and its use admits of dispensing with the valve in the
tube D, and also the ordinary separate cock to which the screw stem A is screwed
and which also connects it to the steam chest or other part of the engine. In
figure 2 a lateral screw valve and seat chamber I, I, are shown as formed in the
stem A, A¹ (instead of the cock K shown in figure 1A) which controlls both the
emission of the oil from the tube a, and also the admission of the steam led up this
same tube a through the top where it is jointed by a coupling a³ to the tube D'

page_text: leading the steam in this case to same condensed water tube D" shown in figure 1,
but by this means dispencing with the lower part and bend D of the tube D¹. In
the modified form of our lubricator shown in figure 3, the sight glass tube C¹ and
its connections are for simplification and symmetry of construction, fitted in the
centre line on the top B¹ of the lubricating vessel B (instead of to the one side as
in figures 1 and 2, and has its top socket C supported from the lower socket C³ by
side open bars, and is connected above by a screw top C₁ for the insertion and
removal of glass, and joint coupling at a connecting it to the bend a³, in this case
conduct the ejected oil into the steam tube D', which is thus made to emit the oil
as well as to conduct the steam to the condensed water tube D", which may lead
the water to the bottom of the oil vessel B direct by the valve d d¹ and tube d
as shown in figure 1, or otherwise the tube D" may be conducted down to and
connected by a coupling and knee bend as dotted in at D' to the valve chamber E
in the stem A similar to that of the bend D of the steam tube D¹, but higher up in
a solid part of the neck A¹ of the stem A.
A lateral conical pointed screw valve E' is fitted to open or shut off the water
from the tube D" and its bend D and valve chamber, E to the bottom of the oil
vessel B by the small tube e in the stem throat A¹; and when this valve E E' is
used the water valve d, and tube of the form shown in figure 1 would be
dispensed with. In the arrangement, Figure 3, the central tube a, a, may still be
retained, but used for a different purpose, and made short and only fitted between
the bottom of the glass tube C¹ and the water chamber E at the throat A' of the
stem A where a small tube 6 leads to this chamber, through the controlling conical
pointed screw spindle valve b', fitted on the stem A, A¹ on the opposite side to the
valve E. This arrangement of valve 6' and tubes ba. a leading between it and
the glass tube (though not necessary to the working of our lubricator) is preferred
to be fitted to this arrangement for clearing out the glass and these tubes leading
to and from it. And it is preferred also to fit a small screw valve as indicated at F
near the top of the oil vessel B of our said improved lubricators for letting off the
air when the other valves are shut.
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. The combination and arrangement of the parts of automatic sight lubricators
of the portable self contained construction, carried on a central stem, and having
their sight glass tubes fitted at the top of the lubricating vessel, so as to take the
oil or lubricant direct therefrom, substantially as herein described, and shown in
the accompanying Drawings.
2. In portable sight feed lubricators, the fitting of their sight glasses at the top
of their lubricating vessels, so as to take the oil or lubricant direct therefrom,
substantially as herein described, and shown in the accompanying Drawings.
