I, REGINALD HADDAN, of the firm of Herbert & Co., Patent Agents, of 67 Strand,
London in the County of Middlesex, Civil Engineer, do hereby declare the nature of
this invention to be as follows:-
-
Referring to the accompanying drawings of which Fig. 1 is a vertical and median
section of a lubricator for oiling both the engine cylinders and their valves and pistons
-the plane of such section being taken through the line of the axes of the oil educts
leading in opposite directions from such lubricator, to the valve chests of the said
cylinders.
Fig. 2 is a vertical and median section of the lubricator, the plane of such section
being at right angles to that of Fig. 1.
Fig. 3 is an elevation of the lubricator as applied to a boiler, and having both its
sight feed chambers arranged so as to be seen by the engineer when in his usual
position next the right side of the cab of the engine.
Fig. 4 is a horizontal section taken on line 1. 1. of Fig. 2.
Fig. 5 is another horizontal section taken on line 2. 2. of Fig. 2.
Fig. 6 is a horizontal section taken on line 3.3. of Fig. 1.
Fig. 7 is a vertical section taken on line 4. 4 of Fig. 5 and showing the passages
or parts leading to one of the sight feed glass tubes.
In this improved lubricator, the two sight feed glass tubes of it, are arranged at one
side of the oil reservoir, rather than on opposite sides thereof, as is the usual custom,
the arrangement of them being to admit of both being readily seen by the engineer
when at his post in the cab of the engine.
In the drawings A denotes the oil reservoir, and B the steam condenser of the lubricator.
In the lower part and on one side of the oil reservoir is a pocket or chamber a see
Figs. 2, 4 and 5; from the middle part of which a tube b rises nearly to the top of the
oil reservoir and opens into such pocket and reservoir.
Extending up through the central part of the oil reservoir is a post C in which are
four passages c, d, d and e, which are arranged as represented in Figs. 1, 2, 4 and 5,

page_text: the median one c, extending from the top of the post, downward, half or about half
the length of such post-and opening into a tubular branch conduit f, extending
laterally from it to the side of the reservoir and opening into a tubular supporting
shank g, through which steam from the boiler is to pass into the part f. and thence to
and into the passage c. and thence through a tube c¹ into the condenser-the said
tube c¹ being in continuation of the passage c. and at top having in it a valve h¹ to
open upward. The shank 9. is supported by a bracket i extending from the boiler K.
see Fig. 3-such shank being to receive steam from such boiler and also to serve as a
support for the lubricator.
The tube c¹ is between two other tubes d' d¹ whose upper ends are at a short
distance below that of the tube c'. These tubes d¹ d¹ lead upward into the condenser
from the passages d. d. which at their lower ends open into two branch educts h. h.
arranged as shown in Fig. 1 and leading to the two valve chests of the steam cylinders
of the locomotive engine.
The passage e. leads from the lower part of the condenser downward within the
post C and thence turns upward and opens into the oil reservoir-all being as shown
in Fig. 2 there being on the top of such oil reservoir a filling orifice k provided with a
screw plug l. for closing it.
From the pocket a two educts m are led in radial directions, relatively to the oil
reservoir, as shown in Fig. 5. Each of such educts opens into one of the two lower
vertical carriers or supports of the two sight feed glass tubes o. o. whose upper vertical
carriers or supports, shown at p. p. in Figs. 2 and 4, communicate directly with the
vertical passages d. d. in manner as represented in Fig. 4. To each educt m. there is
a stop cock 9 (see Fig. 5) to regulate the discharge of oil into the next adjacent sight
feed tube--and there is at the lower part of the oil reservoir and opening out thereof,
a drainage pipe r, provided with a stop cock s-see Fig. 2.
On and projecting upwards from such drainage pipe is fixed a lantern D. which is
arranged so as to illuminate both of the sight feed tubes-the arrangement of it being
as shown in Figs. 2 and 5.
The steam entering the lubricator through the inducts g and f. passes into the ducts
c. and c and thence into the condenser B, from which the water of condensation
flows, by the ducts e and el into the oil reservoir, displacing the oil therein and causing
it to flow into and down the pipe b and thence into the pocket a. From the said
pocket, the oil passes into and up through the sight feed glass tubes-it escaping into
them through their induction nipples t. and flowing in drops up through such tubes,
or the water therein, and thence into the conduits p. p. and thence into the steam
passages d. d. to and into the branch educts h. h. by which the steam, charged with
the oil, is conveyed to the valve chests of the cylinders of the engine.
There is to each educt h. a common oil cup E, having to its discharging orifice, a
screw plug F. Within the tube h. and directly underneath each cup E, is a transverse
partition u see Figs. 1 and 6-above which is a duct v. leading to the discharging
orifice of the cup, and also into the part of the tube h. which is in advance of the
partition. Within such duct v. is a valve w whose seat is at the top of a passage w
in the partition u and opening into a branch a. that communicates with the bore of the
part of the tube h. which is in rear of the partition. There is to the branch x. a screw
plug y,-
-see Fig 2-to act against and close the mouth of the passage w'.
When the plug F, is closed on its seat and the plug y, is off its seat, no oil from the
cup E can escape, the steam passing through the passages h and w¹ and forcing
upward the valve. But when the plug F, is off its seat and the plug y. is closed on
its seat, oil from the cup can flow into and through the pipe h. to the valve chest of
the cylinder-the steam to the said chest and for operating the piston being at the
time shut off.

I, REGINALD HADDAN, of the firm of Herbert & Co., Patent Agents, of 67, Strand,
London, in the County of Middlesex, Civil Engineer, do hereby declare the nature
of the said invention, a communication to me from abroad by Warren Hilliard
Craig of Massachusetts, United States of America, Manufacturer, and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
Referring to the drawings filed with the Provisional Specification of which
Figure is a vertical and median section of a Lubricator for oiling both the engine
cylinders and their valves and pistons-the plane of such section being taken through the
line of the axes of the oil educts leading in opposite directions from such lubricator,
to the valve chests of the said cylinders.
Figure 2 is a vertical and median section of the lubricator, the plane of such section
being at right angles to that of Figure 1.
Figure 3 is an elevation of the lubricator as applied to a boiler, and having both
its sight feed chambers arranged so as to be seen by the engineer when in his usual
position next the right side of the cab of the engine.
Figure 4 is a horizontal section taken on line 1. 1 of Figure 2.
Figure 5 is another horizontal section taken on line 2. 2 of Figure 2.
Figure 6 is a horizontal section taken on line 3. 3. of Figure 1.
Figure 7 is a vertical section taken on line 4. 4. of Figure 5 and showing the
passages or parts leading to one of the sight feed glass tubes.
The nature of the invention is duly defined in the claim or claims hereinafter
presented.
In the improved lubricator, the two sight feed glass tubes of it, are arranged at one
side of the oil reservoir, rather than on opposite sides thereof, as is the usual custom,
my arrangement of them being to admit of both being readily seen by the engineer
when at his post in the cab of the engine, such post being close to the right side of
the cab, the usual arrangement in which the reservoir is directly between the two
sight feed tubes, causing one of them to be behind and so covered by the reservoir
as to be out of sight of the engineer, who to obtain a view of it has to leave his
position.
In the drawings A denotes the oil reservoir, and B the steam condenser of the
lubricator. In the lower part and on one side of the oil reservoir is a pocket or

page_text: chamber a see Figures 2, 4 and 5 from the middle part of which a tube b rises nearly
to the top of the oil reservoir and opens into such pocket and reservoir.
Extending up through the central part of the oil reservoir is a post C in which are
four passages c, d, d and e which are arranged as represented in Figures 1, 2, 4 and 5
the median one c extending from the top of the post, downward, half or about half
the length of such post-and opening into a tubular branch conduit f extending
laterally from it to the side of the reservoir, and opening into a tubular supporting
shank g through which steam from the boiler is to pass into the part f- and thence to
and into the passage c and thence through a tube c¹ into the condenser―the said
tube c¹ being in continuation of the passage c and at top having in it a valve to
open upward. The shank g is supported by a bracket i extending from the boiler K
see Figure 3-such shank being to receive steam from such boiler and also to serve
as a support for the lubricator.
The tube c¹ is between two other tubes d'd' whose upper ends are at a short distance
below that of the tube c¹. These tubes d'd¹ lead upward into the condenser from the
passages dd which at their lower ends open into two branch educts hh arranged as
shown in Figure 1 and leading to the two valve chests of the steam cylinders of the
locomotive engine.
The passage e leads from the lower part of the condenser downward within the
post C and thence turns upward and opens into the oil reservoir-all being as shown
in Figure 2 there being on the top of such oil reservoir a filling orifice k provided
with a screw plug 1 for closing it.
From the pocket a two educts m are led in radial directions, relatively to the oil
reservoir, as shown in Figure 5. Each of such educts opens into one of the two lower
vertical carriers or supports of the two sight feed glass tubes oo whose upper vertical
carriers or supports, shown at pp in Figures 2 and 4 communicate directly with the
vertical passages d d in manner as represented in Figure 4. To each educt m there
is a stop cock q (see Figure 5) to regulate the discharge of oil into the next adjacent
sight feed tube-and there is at the lower part of the oil reservoir and opening out
thereof, a drainage piper provided with a stop cock s-see Figure 2.
On and projecting upwards from such drainage pipe is fixed a lantern D which is
arranged so as to illuminate both of the sight feed tubes-the arrangement of it being
as shown in Figures 2 and 5.
The steam entering the lubricator through the inducts 9 and passes into the
ducts c and c¹ and thence into the condenser B from which the water of condensation
flows by the ducts e and e¹ into the oil reservoir, displacing the oil therein and causing
it to flow into and down the pipe b and thence into the pocket a. From the said
pocket, the oil passes into and up through the sight feed glass tubes-it escaping into
them through their induction nipples t and flowing in drops up through such tubes,
or the water therein, and thence into the conduits pp and thence into the steam
passages dd to and into the branch educts hh by which the steam, charged with the
oil is conveyed to the valve chests of the cylinders of the engine.
There is to each educt a common oil cup E having to its discharging orifice, a
screw plug F. Within the tube hand directly underneath each cup E is a transverse
partition u see Figures 1 and 6 above which is a duct v leading to the discharging
orifice of the cup, and also into the part of the tube h which is in advance of the
partition.
Within such duct vis a valve w whose seat is at the top of a passage w³ in the
partition u and opening into a branch a that communicates with the bore of the part
of the tube which is in rear of the partition. There is to the branch a screw
plug y see Figure 2-to act against and close the mouth of the passage w¹.
When the plug F is closed on its seat and the plug y is off its seat, no oil from the
cup E can escape, the steam passing through the passages h and w₁ and forcing
upward the valve. But when the plug F is off its seat and the plug y is closed on
its seat, oil from the cup can flow into and through the pipe h to the valve chest of the
cylinder the steam to the said chest and for operating the piston being at the time
shut off.
