IMPROVEMENTS IN AUTOMATIC SIGHT FEED LUBRICATORS
Year: 1884

page_text: WILLIAM DIXON The Mount Ballymacarrett Co Down Ireland Brass-Founder,
do hereby declare the nature of my invention for IMPROVEMENTS IN AUTOMATIC
SIGHT FEED LUBRICATORS to be as follows:-
I pass the steam supply for the condenser in a tube through the body of the
lubricant, thereby making available suet, tallow, or other heavy lubricants for
steam cylinders and valves.
At the bottom of the cup I form a steam pocket and join it to the condenser in
the top of the cup by a tube. The steam enters the pocket through a branch and
cock below the cup, and ascends through the tube to the condenser heating the
lubricant on its way. The condensed steam descends into the cup by a down tube
and presses the lubricant through the upper branch of a sight.feed glass at one
side of cup and out by the branch and cock below the cup. The condensed water
is removed from the cup by a drain cock; and the lubricant poured in through a
filler and cock at one side The air in the cup and condenser is removed by an up
tube on top of the cup and an air cock in the condenser.

page_text: I WILLIAM DIXON The Mount Ballymacarrett in the County of Down, Ireland,
Brass Founder do hereby declare the nature of my invention for IMPROVEMENTS
IN SIGHT FEED LUBRICATORS 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 that class of Lubricators known as Sight Feed. It
will be best understood by reference to the accompanying drawing, which is a
vertical section of a Lubricator constructed according to this Invention.
A is the oil cup, which may be made of brass, cast iron, white-metal or glass.
I do not bind myself to the kind of material of which the cup may be made. B is
the condenser fixed on the centre of the cup A. B' is a down tube for the
condensed steam into the oil cup. C is a steam pipe connecting the condenser
with the steam chamber D. D is a steam chamber cast in the bottom of the oil
E is a steam cock
cup A and in communication with the steam cock & branch E.
and branch opening into the main steam pipe. F is a glass tube connecting the
top of the oil cup with the steam chamber D and the exit E. G is a regulating
tap for regulating the flow of the lubricant through sight glass F. H is a filling
cup & tap. I is a drain tap & pipe for running off water. J is an air cock on the
top of the condenser.
The action of this Lubricator is as follows. After blowing steam through the
closed: H and J are
cup A and sight glass F and drip cock I; the steam cock E
J and H are closed
opened and the Lubricant poured in at H till the cup is full.
and E opened to admit the steam to the chamber D and through C to the
condenser B: the condensed steam descends to the oil cup A. through the pipe B¹,
and floats the lubricant K through G down the sight glass F and into the main
steam pipe through the chamber D and branch E. The tap G regulates the drops
of lubricant.
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
1st The passing of the steam supply to the condenser through the body of the
Lubricant in the cup A by the steam pipe C to the condenser B, thereby heating
and making available suet, tallow and other heavy Lubricants for steam cylinders
and valves.
2nd The placing of the condenser B on the centre of the top of the oil cup A,
thereby saving extra pipes and connections when the condenser is separate from
the oil cup.
