PROVISIONAL SPECIFICATION.
Self Acting Lubricator for Piston Rods of Steam Engines.
I JAMES BRADLEY 59 Sandycove Road Kingstown Co. Dublin Marine
Engineer do hereby declare the nature of this invention to be as follows:-
This invention is for the purpose of blowing the lubricant on to the piston rods
of steam engines by means of the steam that enters the cylinder at every stroke
of the engine, when the piston rod commences its inward stroke.
According to my invention this is accomplished by the following means.
A small spring valve and box are placed on that side of the cylinder, through
which the piston rod works, in such a position that when the steam enters the
cylinder on this side, it forces open this valve, from this valve box, a pipe is
attached leading to and under a second small spring valve and box, and from thence
to and encircling piston rod, this pipe may be called the lubricating pipe.
In this lubricating pipe where it encircles piston rod, are a number of openings
to allow the lubricant to be blown on to the piston rod.
An oil tank is placed in a suitable position having a pipe leading from it, to a
funnel shaped pipe in the second spring valve box, the flow of the lubricant being
regulated by means of a small valve or cock, and the pipe so placed, that the
lubricant may be seen dropping or flowing into the funnel shaped pipe.
The lubricant flows through the funnel shaped pipe, and through second spring
valve box into lubricating pipe from whence it is blown on to the piston rod.
The two spring valves are so constructed that the compression on the springs can
be regulated as desired.
When the steam acts on the first mentioned valve and forces it open, the steam
pushes through the lubricating pipe and carrying with it any lubricant that may
be in the pipe, blows it on to the piston rod, at the same time closing the second
spring valve.
When the steam is exhausting from the cylinder, the first valve closes, and the
second valve opens, and allows the lubricant to flow into the lubricating box, ready
to be blown on to the the piston rod in its proper time.

Engineer 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 is for the purpose of blowing the lubricant on to the piston rods
of steam engines, by means of the steam that enters the cylinder at every stroke
of the engine, when the piston rod commences its inward stroke.
According to my invention this is accomplished by the following means.
As shown in the accompanying drawing the small spring valve A, Fig. 1 is
placed on that side of the cylinder through which the rod works, with the pipes H
leading from it to the piston rod F, and encircling same, the pipe H passes through
the bottom part of valve box B.

page_text: The spring valve B, is to allow the lubricant to flow in to the pipe H.
In the pipe H, where it encircles piston rod as shown in Fig. 3 there are a number
of openings through which the lubricant is blown onto the piston rod.
The oil tank G, is for containing the lubricant, the lubricant flows from the tank
into a funnel shaped pipe leading into the valve box B, the How being regulated
by the small valve D, and so placed, that the lubricant can be seen flowing into
the funnel shaped pipe.
When the steam enters the cylinder K, on the side next the valve A, as shown
in Fig. 2, it forces open the valve A, and blows any lubricant that is in the pipe H,
on to the rod F, at the same time the pressure of steam closes the valve B.
When this steam exhausts from the cylinder K, the valve A closes, as shown in
Fig. 1, at the same time the valve B, and allows the lubricant to flow into the pipe
box H and from there blown onto the rod at its proper time.
The spring valves A and B are so constructed, that the compression on the springs
can be regulated as desired, and the springs may be placed either inside or outside
the valve boxes.
This invention may also be applied to lubricate other parts of engines.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner, the same is to be performed, I declare that what I
claim is.
The lubricant is blown onto the parts to be lubricated by means of the steam
that enters the cylinder, in the manner indicated on the drawing, and by the means
or appliances hereinbefore described.
