page_text: I, PHINEAS ALLEN BENNETT of Chicago, in the County of Cook and State of
Illinois, United States of America, Mechanical Engineer, do hereby declare the
nature of my invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
My invention relates to that class of lubricators in which the pressure of a
hydrostatic column is employed to feed in a gradual and uniform manner the
oil or other lubricant into the steam chest, cylinder &°.
And my present improvement has for its object; to supply a simple and effective
means to attain a uniform and continuous condensation of steam, with a free and
direct back or overflow into the Engine pipe of the surplus water of condensation,
and thus enable the apparatus to work properly during cold weather, or in exposed
situations, and at the same time entirely obviate the danger of the condensing
chamber filling with water, and rendering the apparatus inoperative. Also to
furnish means to attain a ready and direct reflux or overflow of the surplus water
of condensation and also prevent the oil feed or flow from being carried up into
the condensing chamber by the incoming volume of steam and in consequence
admit of the use in common of a single horizontal passage to admit the supply
of steam to the condenser and conduct the oil and overflowing water of condensation
into the steam pipe.
To enable others skilled in the art to which my invention appertains to make
and use the same I will now proceed to describe its construction and mode of
operation, referring to the annexed drawing which represents in vertical section
my improvements adapted to a sight feed lubricator.
The general form and arrangement of the lubricator parts will be substantially
the same as any other sight feed lubricator, in which the oil is gradually displaced
and fed by the pressure of a hydrostatic water column.
In the drawing A representing the oil receptacle B the condensing chamber
superimposed above said reservoir or receptacle and connected thereto by a tubular
neck C the upper end of which is open and is screw threaded for the attachment
of the condenser B; while its lower end is closed and provided with a downwardly
extending tube C¹ for conveying the water of condensation to a point beneath the
oil contained in said oil receptacle.
The volume of steam to supply the hydrostatic column is introduced into the
condenser B by a horizontal branch neck or passage D arranged some distance
below the upper end of the vertical neck C with its outer end in communication
with the steam pipe F of the engine; the oil as it is fed from the oil receptacle
passing through & bent neck sight feed E that communicates with the branch
neck D.

page_text: My present improvement as applied to the form of lubricator above. described
consists in dividing the upper open end of the neck C, by a transverse partition G
so as to form the main chamber H for the body of water constituting the operating
hydrostatic column of the apparatus, and a combined return or overflow passage I
for the surplus water of condensation, and an inlet passage for the steam supply
into the condenser B; the horizontal portion of said passage I is arranged out of
line with, and above, the axis of the main passage D so as to form an abutment
shoulder or offset J to prevent the oil from being carried up through. the passage I
into the condenser by the incoming steam; and at the same time form an impedi-
ment to break up the body of incoming steam and in such condition cause its more
rapid condensation by contact with the returning water of condensation.
The advantages of my improved construction as above set forth are as follows:-
.1 Certainty of action in cold weather or in feeding heavy oils, due to the
constant warm feed attained by my improved construction.
2nd It readily admits of the connecting shank C containing the hydrostatic
column being made of any desired beight to attain any required degree of operating
pressure that circumstances or quality of the oil used may require.
3rd It requires the use of but a single connection to the steam pipe of the engine
by admitting of the use of a single passage to introduce steam into the apparatus,
and carry the oil and surplus water of condensation into the engine steam pipe and
4th It prevents any possibility of a vacuum forming in the condenser and rendering
the apparatus inoperative.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In a lubricator operated by a hydrostatic column, as described, a vertical
connecting neck, between the condenser and the oil receptacle, having its upper
end open, and provided with a transverse partition and a horizontal branch passage,
common to the incoming steam and oil feed and adapted to receive and carry off
the surplus water of condensation essentially as set forth.
2. In a lubricator operated by a bydrostatic column, as described, an open ended
vertical neck C connected to the condenser B and provided with a transverse parti-
tion G in combination with the horizontal passage D having communication with
the steam pipe of the engine and the oil feed essentially as set forth.
3. In a lubricator operated by a hydrostatic column as described the horizontal
branch passage D common to the incoming steam and oil feed, the inner end of
which communicates with the contracted passage I, that is arranged above the
central axis of said passage D so as to form an abrupt shoulder or offset J, at the
inner and lower end of the same essentially as set forth.
4. In a lubricator operated by a hydrostatic column, the combination with the
condenser B and oil receptacle A of the open ended connecting neck C partition G,
horizontal branch passage D and passage I ending in an offset J essentially as set
forth.
5. In a lubricator operated by a hydrostatic column, as described, the combina-
tion of the condenser B connecting neck C, partition G passages I and D shoulder
or off set J sight feed tube E and oil receptacle A, essentially as set forth.
