PROVISIONAL SPECIFICATION.
Improvements in Lubricators.
I, FREDERICK WILLIAMSON, of 95, Toronto Road, Tilbury, in the County of
Essex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in lubricators used for lubricating the
inside surfaces of steam cylinders, and slide valve faces, and has for its object to
obviate the contact of steam with the lubricant before the latter is fed to the
pipe leading to its destination, thus preventing the formation of condensed steam
in the lubricator and hence waste of the lubricant.
For this purpose I provide a rectangular or other suitably shaped metal chamber
or vessel the base of which is formed in the interior thereof with a planed surface
upon which slides a metal block whose under or sliding surface is provided with
two narrow indentations or grooves arranged at a short distance from one another.
The aforesaid planed surface is formed with two recesses or parts at such a distance
apart that the sliding block in its movement to and fro never permits one of the
said ports to be uncovered. This latter port is connected to the oil supply by a
pipe which feeds the oil by gravity or pressure to the said port, whilst the other
port is connected by another pipe to the cylinder or valve face of the engine. As
the sliding block is operated, from a working part of the engine or otherwise, the
two indentations or grooves formed in its under surface are filled with a sinall
quantity of oil from the covered port and carry such oil into the uncovered port
where it is alone subjected to the pressure of steam in the rectangular chamber for
the purpose of feeding it to the parts to be lubricated.
Instead of a rectangular chamber a circular vessel may be employed in the
interior of which rotates a solid circular block whose periphery is formed with four
or other suitable number of small indentations or recesses. This block rotates in a
cylinder partly surrounding it which is connected to the oil supply. As the block
rotates its recesses carry a small portion of the oil around with them until they
reach the open part of the cylinder in which the block rotates, whereupon the oil
escapes from the said recesses and is subjected to the pressure of steam in the
circular vessel for feeding it to the parts to be lubricated.
As a further variation a disc may be used having a similar action and result to
those hereinbefore referred to.
As my improvements are capable of some modifications without departing from
the principle thereof 1 do not restrict myself to material, dimensions or to the
precise forin or placement of the parts thereof.

COMPLETE SPECIFICATION.
Improvements in Lubricators.
I, FREDERICK WILLIAMSON, of 95, Toronto Road, Tilbury, in the County of
Essex, Engineer, do hereby declare the nature of this invention, and in what manner
the same is to be performed, be particularly described and ascertained in and by
the following statement :-
My invention relates to improvements in steam lubricators, and has for its
object to convert the oil used for lubricating purposes into a gaseous form in which
it is carried away by the steam to the various parts requiring to be lubricated.

page_text: My invention has also for its object to avoid the injury hitherto caused by steam
boilers owing to the liquid particles of oil which were carried therein and helped to
form solid impurities which inernsted the said boiler.
In carrying my invention into practice I provide a spherical casing having a
pipe at the top through which oil is fed from any convenient source to adjustable
recesses or cups formed in a rotary disc set in motion by any suitable mechanism
actuated by steam from the boiler. This disc rotates upon a spring bearing and is
carried in the outer casing aforesaid by two journals one of which acts as a shaft
and receives a rotary motion from the mechanism above mentioned. The above
lubricator is used in conjunction with a perforated cylindrical casing the ends of
which are bent up inwardly so as to form a conical recess resembling the bottom of
a wine bottle. The apparatus is inserted between two sections of the steam pipe
in front of the stop valve.
In the accompanying drawings,
Fig. 1 shows in longitudinal section the application of my improved steam
lubricator to the steam pipe of a locomotive or other engine.
Fig. 2 shows in vertical section the arrangement of my improved steam lubricator
for use in connection with marine engines.
Fig. 3 is a section of the upper part of the lubricator at right angles to
Fig. 2.
Fig. 4 is horizontal section on line . of Fig. 3.
Like letters of reference indicate corresponding parts throughout the drawings.
Referring to Fig. 1, the spherical box or easing A is furnished with a supply
pipe a and a delivery pipe 6, the pipe a being connected to any suitable oil reservoir,
while the pipe is screwed through the plate bolted to the pipe B and to the
flanges of the perforated casing (having the shape shown in the figure and the
edges of which are raised inwardly to form a cone the apex d of which is in a line
with the axis of the pipe b. The pipe B is inserted between two sections of the
steam pipe of an engine in front of the stop valve. The rotary disc which is
furnished with openings to lighten its weight is provided with journals turning
within the flange a' of the easing A. The journal acts as a shaft and receives a
rotary motion from any suitable mechanism actuated by steam from the boiler
the mechanism which is not shown in the drawings forming no part of my
invention.
The said disc turns between the bearings g the former of which is furnished
with projections or legs entering suitable recesses formed in the spherical box A,
spiral springs being wound upon the said legs to render the bearing g resilient. The
dise is further furnished with four recesses i i. etc., the bottom of which is
formed of a headed screw j. etc. whereby the capacity of such recesses may
be decreased when required. As the disce is set in rotation every recess comes
successively under the oil supply pipe to be filled, its contents being subsequently
emptied as it turns further round into the spherical casing from which it drips
through the pipe beach drop falling exactly on the apex d by which it is divided
into a number of minute particles dashed into the perforated casing C through
which they are carried by the incoming steam from the boiler and converted owing
to the intense heat of the same into a gus which is propelled with the steam to the
parts requiring to be lubricated.
Referring to Figs. 3 and 4 the spherical casing A and disc e contained therein as
above described, are adapted to a vertical and cylindrical casing D furnished with
a suries of delivery pipes ... (Fig. 4) through which the minute particles of
oil are carried in a gaseous state by the steam admitted at m to the parts of
the marine engine requiring lubricating. The pipe loads the oil dropped from the
recesses i. into a drip cup from which only one drop can fall upon the
apex of the cone E which is made of glass and fluted as shown at o
(Figs. 3 and 4) being carried by the flange f formed on the bottom 9 screwed in
the casing D as shown.
etc.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The improved lubricator consisting of a spherical casing A containing a
rotary disc e which is furnished with adjustable recesses i. etc. and turns
within bearings gh upon journals ff within a flange of the casing A, the latter
being furnished with an oil supply pipe a and a delivery pipe substantially as herein
described, and for the purpose set forth.
(2) The application to the steam pipe of locomotive and other engines of the
lubricator above claimed in combination with a perforated conical casing C arranged
in such a manner that each drop of oil falling from the delivery pipe is split into
minute particles by the inner apex d of such casing substantially as described and
shown in Figs. 1 and 2 of the drawings, and for the purpose set forth.
P
(3) The application to marine engines of the lubricator above claimed in com-
bination with a drip cup n and a casing D perforated at the bottom and furnished
with a fluted glass cone E substantially as herein described and shown in Figs. 3
and 4 of the drawings, and for the purpose set forth.
