Engineer, do hereby declare the nature of this invention to be as follows:-
In my improved system the ordinary oil cups are dispensed with, and the oil,
water, or other lubricating fluid introduced to, the various bearings under pressure.

The bearings may be fitted with packing rings, or some other device for retarding
escape of the lubricant.
The advantages to be derived from the application of this system are:-
1st. That the lubricant being introduced under pressure will immediately fill any
spaces which may exist between the journals and their bearings, and by so conducing
to the smooth working of the engine it may be run at a higher speed than heretofore
found practicable.

COMPLETE SPECIFICATION.
An Improved System of Lubricating the Working Parts of Steam
or other Engines.
I, ALBERT CHARLES PAIN, of No. 18, Noel Road, Edgbaston, Birmingham,
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 consists of the improved system hereinafter described and illustrated
in the accompanying drawing of lubricating the working parts of steam or other
engines
In
my improved system the ordinary oil cups are dispensed with the oil water or
other lubricating liquid being introduced to the various bearings under pressure
from a pump accumulator or high level tank by a continuous system of oil ways
drilled through the shaft or journal with holes radiating therefrom to the surface to
be lubricated as hereinafter described.
The lubricating liquid which escapes from the bearings may be collected in a
save-all from which the pump may be arranged to take its supply.
The bearings may be fitted with packing rings or other device for retarding the
escape of the lubricant if considered advisable.
The advantages derived from the application of my improved system are:-
First-That the lubricant being introduced under pressure will immediately fill
any spaces which may exist between the journals and their bearings and thus
conduce to the smooth working of the engine and the said engine may be run at a
bigher speed than heretofore found practicable without knocking.
Second-The bearings being very efficiently lubricated the loss of power by
friction will be less.
Third —A cheaper form of lubricant may be used having less body.

page_text: I will now proceed to describe with reference to the accompanying drawing the
manner in which my invention is to be performed.
Figure 1 represents in horizontal section my improved system of lubricating
applied for the purpose of illustration to the principal bearings of an ordinary
horizontal single crank steam engine and Figure 2 represents in section and elevation
the cross head bearing and guide shoe of the same the sectional part of Figure 2
being taken in a plane at right angles to that in which the corresponding part of
Figure 1 is taken.
The same letters of reference indicate the same parts in both figures.
A is the crank shaft; 13 the crank pin bearing; C C are the two main bearings
on either side of the crank pin bearing B D is the eccentric sheave; E the cross
head bearing and F the cross head guide shoe best seen in Figure 2. In the crank
shaft A. the central oil way G G G is drilled. From this central oil way other oil
ways radiate marked respectively 0 0 0 and 0. It will be seen by an
examination of the drawing that the branch or radial oil ways O and O¹ convey
the oil from the central way G to the two main bearings C C of the crank shaft
and the radial oil way O" conveys the oil to the eccentric sheave D and the radial
oil way conveys the oil to the crank pin bearing B. Each of the radial oil
ways Ŏ, O¹ and Qi opens into and delivers the oil to a circumferential or annular
groove M and M' turned in the surfaces of the respective brasses as represented in
the drawing.
The lubricant under pressure produced by a pump hydraulic accumulator or high
.level tank is introduced at one end of the central oil way G by a pipe H connected
thereto by a swivel joint. From the central oil way G the oil under pressure is
conveyed to the branch or, radial oil ways 0 0 0 0 and is delivered into the
circumferential or annular grooves in the brasses B C C and to the eccentric
sheave D whereby the efficient lubrication of the said brasses and sheave is
produced.
Instead of conveying the oil or lubricant under pressure direct to the end of the
main or central oil way as represented in the drawing the said oil or lubricant may
be conveyed first through holes drilled in the caps and brasses of one or both of the
main bearings C C and communicating with the circumferential or annular
grooves M M and thence by the radial or branch oil ways 0 0¹ to the central oil
way G and parts in connection therewith. When the cross head pin bearing is to
be lubricated from the oil way by which the crank shaft bearings and eccentric
sheave are lubricated the arrangement represented in the drawing is employed.
That is to say opening into the groove M' around the crank pin A is an oil way I
drilled in the connecting rod P the said oil way I being connected by the outside
pipe to the oil way represented, passing through the axis of the cross head
pin E from which last named oil way the radial oil hole represented passes to the
circumferential or annular groove M in the cross head pin bearing E. From the
groove M another oil hole K (see Figure 2) leads to the cross channel Lin
the face of the guide shoe F. The face of the other guide shoe not represented
is lubricated in a similar way. The bearing of the cross head pin and the faces of
the guide shoes are thus efficiently lubricated.
The surplus lubricating oil or fluid escaping from the bearings and other working
parts may be collected in a save-all not represented in the drawing from which
save-all the pump feeding the main or central oil way and the oil ways and pipes in
communication with it takes its supply.
By the method described and illustrated of lubricating the bearings and working
parts of steam or other engines the advantages obtained over the ordinary system
have hereinbefore been pointed out.
Although I have only described and illustrated my invention as applied to the
lubricating of the principal bearings of an ordinary single crank steam engine yet I
wish it to be understood that my improved system of lubricating is applicable to the
bearings and working parts of steam engines of other kinds and to engines
generally.

page_text: Having now particularly described and ascertained the nature of my inven-
tion, and the manner in which the same is to be performed, I declare that I claim
as my invention
11
The improved system of lubricating the working parts of steam or other engines
hereinbefore described and illustrated in the accompanying drawing; that is to say
forcing oil or other lubricant through the bearings of steam or other engines by
means of a continuous system of channels passages or oil ways in communication
with the working parts of the engine so as thereby to convey the oil or lubricant
under pressure between the said working parts for the purposes and substantially as
described and illustrated.
