Improvements in Lubricators.
We TANGYES LIMITED of Cornwall Works Soho in the County of Stafford
Engineers and THOMAS JEFFERISS of Holyhead Road Handsworth in the County of
Stafford Engineer and CHARLES WILLIAM PINKNEY of No. 5 Regent Street
Smethwick in the County of Stafford Mechanical Engineer do hereby declare the
nature of this Invention to be as follows:-
The said improvements have for their object principally to fit the lubricators for
use with engines worked by steam of high pressure or worked, by compressed air of
high pressure. Lubricators made according to the said invention may however be
employed with steam and compressed air of low pressure.
In constructing a lubricator according to the said invention we make the chamber
for containing the lubricant preferably of a vertical cylindrical figure the hottom of
which is provided with a stem or stalk for connecting it with the part of the engine
to be lubricated. This lubricant passes from the chamber down an axial hole in the
said stem. The top of the chamber is closed by a tightly fitting cap having at its
summit the fixed funnel by which the chamber is supplied with the lubricant. In
the said cap is a horizontal plug with an inner conical termination the inner end of
this plug crosses and works tightly in the bottom of the passage or neck terminating
the charging funnel herein before referred to the conical end of the plug bearing on
a valve seat formed in one side of the said passage or neck. The outer end of this
horizontal plug carries a handle by turning which the said plug can bo made to
advance into or recede from the cap by a screwing motion and the charging valve
thereby opened or closed. The screwed part of the plug works in a packing
box and packing gland for the purpose of preserving the tightness of the parts.
The bottom of the chamber is made sufficiently thick to permit of the formation
in it of a horizontal passage in which a horizontal plug somewhat resembling that
in the cap of the lubricator works. The passage referred to opens into the top of
the axial hole in the stem or stalk down which the lubricant flows. The inner end of
the plug is of different diameters at different parts. The rear part of the inner end
of the plug is of largest diameter the part in advance of that of smaller diameter and
the terminal part of smallest diameter. Between the two parts last named there is
a conical shoulder. In the bottom of the chamber is a small hole opening into the
passage in which the plug works. Through this hole the lubricant passes from the
chamber to the passage in the stem cr stalk under the circumstances hereinafter
explained. A light vertical tube opens at bottom into the passage in which the
plug works and at top into the upper part of the chamber above the surface of the
lubricant. When the last described plug is screwed home by its handle communica-
tion between the chamber and the passage in the stem or stalk is closed.
The action of the parts is as follows:-The lower plug having been driven home
and the upper plug more or less withdrawn oil or liquid lubricant is poured into
the funnel and the chamber filled with the lubricant. The upper plug being driven
home the lower plug is partially withdrawn by unscrewing it by means of its
handle. The first effect of withdrawing the said lower plug is to withdraw the
conical valve near its end from its seat and at the same time to partially uncover
the bottom of the light tube opening at top above the surface of the lubricant.
Steam or air under pressure passes through the open valve through the light
tube to the surface of the lubricant which is thus put into equilibrium.
lubricant passes by its own weight through the small hole in the bottom of the
chamber through the open conical valve to the passago in the stem or stalk and
thence to the cylinder of the engine. The small terminal portion of the plug very
The

page_text: nearly fills the end of the borizontal passage where it opens into the passage in the
stem or stalk and hence only a small stream of the lubricant can pass to the cylinder.
For minute adjustment of the quantity of lubricant passing to the engine the conical
valve on the plug can be brought to any required distance from its seat by turning
the handle of the said plug.
The position of the steam or air tube and the opening through which the lubricant
passes to the cylinder of the engine may be reversed. That is they may be at that
side of the axial line of the lubricant chamber most distant from the handle of the
plug instead of at the side nearest the handle. In this modification the face of the
end part of the plug closes the steam or air tube and the cylindrical part of the said
end of the plug closes the passage for the lubricant. The conical shoulder between
the part of smallest diameter and that of largest diameter closes the communication
between the lubricant chamber and the passage in the stem or stalk of the
lubricator.
In some cases it is desirable for convenience of access or other reason that the
plug herein before described as the lower plug should be situated vertically instead of
horizontally. In such cases we make the said plug work in the axis of the lubricant
chamber the said plug being raised and lowered vertically by the turning of its
handle in one or other direction. The plug has an expanded conical bottom fitting
on a conical sent in the bottom of the lubricant chamber. The plug is hollow
opening at top into the upper part of the chamber and opening at bottom on the
conical face of the expanded bottom of the plug. On the opposite side of the
expanded bottom of the plug is a hole opening at the upper face of the said expanded
part of the plug into the bottom of the chamber and opening at bottom on the conical
face of the said expanded bottom of the plug. On turning the handle of the plug so
as to raise it vertically its conical expanded bottom is raised from its seat when stoam
or compressed air passes up the hollow plug to the top of the chamber and the
lubricant passes through the hole in the expanded bottom of the plug to the cylinder
to be lubricated.

Improvements in Lubricators.
We TANGYES LIMITED of Cornwall Works Soho in the County of Stafford
Engineers and THOMAS JEFFERISS of Holyhead Road Handsworth in the County of
Stafford Engineer and CHARLES WILLIAM PINKNEY of No. 5 Rogent Street
Smethwick in the County of Stafford Mechanical Engineer do hereby declare the
naturo of the said invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
The said improvements have for their object principally to fit the lubricators for
use with engines worked by steam of high pressure or worked by compressed air of
high pressure. Lubricators made according to the said invention may however be
employed with steam and compressed air of low pressure.
In constructing a lubricator according to the said invention we make the chamber
for containing the lubricant preferably of a vertical cylindrical figure the bottom of
which is provided with a stem or stalk for connecting it with the part of the engine
to be lubricated. The lubricant passes from the chamber down an axial hole in the
said stem. The top of the chamber is closed by a tightly fitting cap having at its
summit the fixed funnel by which the chamber is supplied with the lubricant. In
the said cap is a horizontal plug with an inner conical termination the inner end of
this plug crosses and works tightly in the bottom of the passage or neck terminating
the charging funnel hereinbefore referred to, the conical end of the plug bearing on
a valve seat formed in one side of the said passage or neck. The outer end of this

page_text: horizontal plug carries a handle by turning which the said plug can be made to
advance into or recede from the cap by a screwing motion and the charging valve
thereby opened or closed. The screwed part of the plug works in a packing box
and packing gland for the purpose of preserving the tightness of the parts.
The bottom of the chamber is made sufficiently thick to permit of the formation
in it of a horizontal passage in which a horizontal plug somewhat resembling that
in the cap of the lubricator works. The passage referred to opens into the top of
the axial hole in the stem or stalk down which the lubricant flows. The inner end
of the plug is of different diameters at different parts. The rear part of the inner
end of the plug is of largest diameter the part in advance of that of smaller
diameter and the end of the terminal part of smallest diameter is flat. In the
bottom of the chamber is a small hole opening into the passage in which the plug
works. Through this hole the lubricant passes from the chamber to the passage in
the stem or stalk under the circumstances hereinafter explained. A light vertical
tube opens at bottom into the passage in which the plug works and at top into the
upper part of the chamber. When the last described plug is screwed home by its
bandle communication between the chamber and the passage in the stem or stalk is
closed.
The positions of the steam or air tube and the opening through which the lubricant
passos to the cylinder of the engine may be reversed and the lower plug may bo
situated vertically instead of horizontally the vertical plug containing an axial steam
or air passage replacing the steam or air tube before described.
We will now proceed to describe with reference to the accompanying Drawings
the manner in which the said invention is to be performed.
Figure 1 represents in vertical section and Figure 2 in horizontal section a
lubricator constructed according to this invention for use with a high pressure steam
or compressed air engine. The same letters of reference indicate the same parts
in Figures 1 and 2.
a is the cylindrical chamber containing the lubricant and is the stem or stalk of
the same for connecting it with the cylinder or other part of the engine to be
lubricated. In the said stem or stalk b is an axial holo 6 down which the lubricant
from the chamber a passes to the cylinder; c is the tightly fitting screw cap by
which the top of tho lubricant chamber a is closed; d is the fixed funnel by which
the chamber a is supplied with the lubricant ; e is the horizontal plug carried by
the cap e for opening and closing communication between tho funnel d and the
lubricant chamber a, and is the handle of the said plug. The plug e crosses and
works tightly in the passage or neck terminating the charging funnel & and the
conical inner end of the plug bears on the seat fat one side of the passage or
neck; g is the packed gland in which the screwed part of the plug e works as
represented.
In the bottom of the lubricant chamber a is a horizontal passage opening into
แ
the top of the axial hole 6 in the stalk band communication between the lubricant
chamber a and axial passage 6 is effected by the small hole in the bottom of the
chamber a. In the horizontal passage is a screw plug k, ³, 1; the rear part of the
inner end of which plug is of different diameters the part k being of larger
diameter than the part the said part seating itself on the seat m at the top of
the axial hole 6 in the stalk b and closing communication between the chamber a and
the said stalk; is the handle of the screw plug k, and n is the packed gland of the
said plug; p is the light vertical tube opening at bottom into the passage h and at
top into the upper part of the chamber a. The tube p is for the purpose of
admitting steam or air from the axial hole 62 above the lubricant in the chamber a.
The action of the parts is as follows:-The lower plug 1 having been driven
home by turning its handle and the upper plug e more or less withdrawn by
turning its handle oil or liquid lubricant is poured into the funnel & and the
chamber a filled with the lubricant. The upper plug e being driven home the lower
plug k, is partially withdrawn by unscrewing it by means of its handle . The
first effect of withdrawing the said lower plag is to withdraw its end 7 from the seat

page_text: at m and at the same time to partially uncover the bottom of the light tube p
opening at top in the chamber a. Steam or air under pressure passes through the
open valve through the light tube p to the surface of the lubricant which is thus
put into equilibrium. The lubricant passes by its own weight through the small hole i
in the bottom of the chamber a through the open valve at Z to the passage b³ in the stemn
or stalk 6 and thence to the cylinder of the engine. The small terminal portion ? of
the plug very nearly fills the end of the horizontal passage h where it opens into
the passage in the stem or stalk b and hence only a small stream of the lubricant
can pass to the cylinder. For minute adjustment of the quantity of lubricant passing
to the engine the end 7 of the plug can be brought to any required distance from its
sent by turning the handle of the said plug.
By arranging the parts of the lubricator as described and illustrated the chamber a
is free from water when the oil has been delivered from it and hence the use
of drain cocks or other appliances is dispensed with and the valves are easily removed
for cleaning.
Figure 3 represents partly in elevation and partly in section the modification of
the said invention in which the positions of the steam or air tube and the opening
through which the lubricant passes to the cylinder of the engine are reversed; that
is, the said parts are situated on that side of the axial line of the lubricant chamber
most distant from the handle of the plug instead of at the side nearest the handle.
In this modification the conical part m of the plug k, 1 closes the communication
between the passage in the stem and the steam or air tube p which is made in
the thickened wall of the lubricant chamber a, the cylindrical part of the said end
เ
of the plug closing the passage i for the lubricant.
The action of this lubricator is the same as that first described and corresponding
parts are marked with the same letters of reference.
In some casos it is desirable for convenience of access or other reason that the
plug herein before described as the lower plug should be situated vertically instead
of horizontally. This modification is represented in vertical section in Figure 4.
In this modified lubricator the plug for opening and closing the passage 63 in the
stom or stalk b. is marked 9, 9, 7 and is situated and works in the axis of the
lubricant chamber a and is raised and lowered by turning its handle q³ in one or
other direction. The plug 9 has an expanded conical bottom q* fitting on a conical
seat in the bottom of the lubricant chamber. The plug 9 is hollow opening at top
into the upper part of the chamber a and opening at bottom on the conical face of
the expanded bottom of the plug. On the opposite side of the expanded bottom of the
plug is a hole r opening at the upper face of the said expanded part of the plug into
the bottom of the chamber and opening at bottom on the conical face of the said
expanded bottom of the plug. On turning the handle g² of the plug so as to raise it
vertically its conical expanded bottom q³ is raised from its seat when steam or
compressed air passes up the hollow plug 7 to the top of the chamber a and above
the surface of the lubricant and the lubricant passes through the hole in the
expanded bottom of the plug to the cylinder to be lubricated. The filling funnel s
has the shape and position represented in the drawing and the passage is opened
and closed by the screw plug ee.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that we claim
as the said invention of “Improvements in lubricators"
