PROVISIONAL SPECIFICATION.
An Improvement in Sight Feed Lubricators for Steam Engines.
THOMAS WILCOX District Iron Works Smethwick Engine Driver and
FREDERIC LENNOX BROUGHTON District Iron Works Smethwick Iron
Manufacturer do hereby declare the nature of this invention to be as follows:-
:-
By carrying the tube containing live steam upwards through the bottom of the
vessel containing the lubricating oil to the condenser placed above, instead of intro-
ducing it from the top into the condenser, the oil is kept warm so that it passes
freely through the sight feed, and enables any oil, no matter how thick, to be used
without clogging the lubricator, and effects a saving in oil.
By means of a two way tube being used for this purpose the construction is much
simplified, and only one steam connection with the lubricator is necessary, thus
reducing the number of cocks, or valves to two only, and doing away with any
outside tubes except the one supporting the lubricator.

COMPLETE SPECIFICATION.
An Improvement in Sight Feed Lubricators for Steam Engines.
We, THOMAS WILCOX, District Iron Works, Smethwick, Engineer, and
FREDERIC LENNOX BROUGHTON, District Iron Works, Smethwick, Iron
Manufacturer, 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:-
This invention relates to the manner in which we construct and arrange sight
feed lubricators for attachment to steam pipes for supplying engines, whereby we
are enabled to employ a heavier oil or thicker lubricating fluid to be used with
economical results. We are also enabled to secure perfect regularity of feed
owing to the oil or other lubricant used being maintained of equal temperature
even in the most exposed positions in unequal external temperatures.
In carrying our invention into effect we construct our sight feed lubricator for
attachment to a steam pipe preferably in the form shown on the two accompanying
sheets of explanatory drawings in which
Figure is a sectional elevation of our lubricator, Figure 2 a sectional plan
below the condenser, and Figure 3 a detailed sectional elevation of the drain valve
and passage.
On Sheet 2, Figure 4 is a front elevation of our improved lubricator.
We construct the steam inlet valve A with a stop valve plug and spindle in
any well known manner, and we cause the steam to pass right through a tube a a¹
which projects beyond the oil vessel J and enters the condenser G; the steam
passing through the body of oil in the vessel J causes this to become heated and
rendered more capable of passing freely through the sight feed glass H when the
oil valve C is opened. Within the steam conduit pipe a we arrange a second pipe
or passage b which conducts the water from the condenser G to the bottom of the
oil vessel. The valve B is to drain off the water from the oil vessel through the
passage b' when refilling it with oil. We thus carry the passage containing live
steam upwards through the bottom of the vessel containing the lubricant, to the
condenser placed above it instead of introducing the steam from the top into the
[Price 8d.1

page_text: condenser; thus the oil is kept warm, and cheaper or thicker oil may be used.
The oil being introduced into the chamber J through the filling stopper D. We
tix a stopper or plug E over the sight feed glass H for purposes of renewal of the
glass; and we fix an air plug F in the top of the condenser as shown in Figure 1
for the filling of the condenser with water when first starting the lubricator.
cases where the lubricator has been at work, and is stopped long enough to grow
cold, this plug is eased to allow the air which has accumulated to escape.
In
We sometimes arrange a gauge glass I, to show the level of the oil in the vessel J
and we provide an air vent plug or valve K, for releasing the air from the oil
vessel when filling it. We employ any ordinary form of cone or inlet nozzle L to
permit of the oil passing through from the chamber J controlled by the oil valve C.
We modify the shape and configuration of our valve parts together with the
imethod of delivering the oil to suit any particular requirement, or any peculiar
arrangement of steam pipe to which it may be desired to fix it, and we construct the
hand wheels, plugs, taps, gauge glasses and ordinary fittings in any well known
manner.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
,
1. The construction of sight feed lubricators in which the steam conduit pipe or
passage is allowed to pass right through the oil vessel or chamber before entering
the condenser.
2. The construction of sight feed lubricators having the steam conduit pipe or
passage such as a, arranged with a second internal passage or separate pipe such
as b, substantially as and for the purposes herein before described and as illustrated
in the accompanying drawings.
3. The combination and arrangement of a sight feed lubricator having an oil
chamber through which a steam pipe or channel passes to enter a condenser
arranged above it substantially as and for the purposes herein before described and
as illustrated in the accompanying drawings.
