Improvements in Lubricating Apparatus.
We, CHARLES HERBERT BERRY, of 41, Corporation Street, Manchester, Engineer,
and JOHN SNOWDON, Junior, of Westferry Road, Millwall, London, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for lubricating the moving parts of engines
or machinery, and is especially applicable to apparatus for lubricating two or
more parts such as the crank pin and cross head and slides of an engine without
the employment of a cumbrous system of jointed and moving pipes.
In carrying this invention into effect the lubricant is led from its chamber to
a casing formed within or upon or attached to the crank pin, the cranked pipe
which conveys the lubricant having one of its ends entering the casing and the
other entering the lubricant chamber or receptacle in a line co-axial with the
crank shaft as is well understood. The outside of the casing on the crank pin is
turned to form a bearing surface or groove, and the casing is perforated so
that lubricant can pass from the interior of the casing to this external bearing
surface or groove. Upon the groove or bearing surface and so as to be capable
of rotation therein or thereon is placed a recessed ring or collar which is also
perforated and may have a flexible or jointed or other suitable pipe leading to
the cross head or slide blocks. Any lubricant within the casing can thus pass
through it to the external bearing surface or groove and thence through the per-
forated ring or collar and the pipe to the cross head or slide blocks. Suitable
packing devices may be employed to prevent leakage of the lubricant between the
ring and the casing. The casing is also in communication with passages or
channels which pass through the substance of the crank pin and keep its bearing
surface lubricated. The crank pin and the cross head or the slide blocks may thus
both or all be lubricated by the same device.
To reduce the risk of the ring being carried round with the casing a suitable
stopping device may be employed. This may conveniently consist of a projection
from the connecting rod adapted to engage with the pipe leading from the
crank pin to the cross head or slide blocks.
It is preferred, however, to so construct and arrange the apparatus that
each part to be lubricated has its separate and independent supply of lubricant.
This may be effected by employing two pipes to convey the lubricant to the crank
pin casing, one being connected directly to the passages in the crank pin, and the
other opening into the casing so as to supply lubricant to the cross head or slide
blocks. A convenient method of arranging the two pipes is to place one within the
other leaving a space between, the inner pipe conveying the lubricant to the crank

pipes may cease to be concentric or to be contained one within the other after
they have left the stuffing box in the lubricant chamber and may be separately
led to their destinations.
It is also preferred to employ two lubricant chambers or receptacles the annular

We, CHARLES HIBBERT BERRY, of 41, Corporation Street, Manchester, Engineer,
and JOHN SNOWDON, Junior, of Westferry Road, Millwall, London, Manufacturer,
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 follow-
ing statement:-
This invention relates to apparatus for lubricating the moving parts of engines
or machinery, and is especially applicable to apparatus for lubricating two or
more parts such as the crank pin and cross head and slides of an engine without
the employment of a cumbrous system of jointed and moving pipes.
For the purposes of this invention the end of the crank pin is formed or provided
with a circular casing or chamber which is in communication with one end of a
cranked pipe the other end of which is in communication with a lubricant receptacle
and is capable of rotating within a chamber co-axial with the crank shaft. The casing
upon the crank pin opens into the pin itself in such a manner that lubricant
may be conducted to its bearing, and the outside of the casing is formed with a
groove or with a bearing surface. The casing is perforated so that lubricant
can pass from the interior of the casing to this external bearing surface or groove.
Upon the groove or bearing surface and so as to be capable of rotating therein or
thereon is placed a recessed ring or collar which is also perforated for the reception
of one end of a pipe leading to the cross head or slide blocks. Any lubricant
within the casing can thus pass through it to the external bearing surface or
groove and thence through the perforated ring or collar and the pipe to the cross
head or the like. The crank pin and the cross head or the slide blocks may thus
both or all be lubricated by the same device.
In many cases however, it is necessary to provide a separate lubricant for each
part to be lubricated. This may be effected by employing two pipes to convey
the lubricant to the crank pin casing, one being connected as before with the pas-
sages in the crank pin, and the other opening into the casing in such a manner as to
communicate only with the ring surrounding the casing, and thus supply lubri-
cant to the crosshead and similar parts alone. One method of arranging the
two pipes is to place one within the other, leaving a space between, the inner pipe
conveying the lubricant to the crank pin bearing and the space between them
conveying it to the crosshead or vice versa. If desired the pipes may cease to
be concentric or to be contained within one another after they have left the
stuffing box in the lubricant chamber or chambers, and may be separately led to
their destinations.
With two separate and different lubricants two lubricant chambers would be
employed. The annular space between the pipes would then communicate with
one chamber and the inner pipe with the other chamber.
In order that my invention may be more readily understood I have hereto
appended a sheet of drawings to which I will refer hereinafter, and which illus-

page_text: часа 101 Ш apparatus for conveying separate rubricants to the crank pin and to
the cross head.
Figure 1 illustrates in sectional elevation a crank and crank pin and the pipes
and the like for conveying the lubricant.

of the lubricant conveying pipes.
Figure 3 represents a section of part of the pipes at right angles to Figure 2.
Figure 4 illustrates an end elevation of the crank pin casing.
Figure 5 is a section of the crank pin casing at right angles to the section shown
in Fig. 1.
Figure 6 is an illustration of a cross section of the crank pin casing.
Similar letters of reference indicate similar parts where they occur in the
different figures.
A is a crank, B is a crank pin, and C is a casing attached to or formed on the
end of the crank pin. D and E are two pipes connected to the casing and
communicating respectively with the two opening or channels F, G. The other
ends of the pipes D, E are secured to the concentric pipes H, J, and communicate
respectively with the interior of the inner pipe H and the annular space between
them. As shown in Figure 1 these concentric pipes pass through a stuffing box or
the like, and the outer one J communicates through openings with a passage K
leading from or to a lubricant chamber and through which lubricant may be intro-
duced into the annular space between the concentric pipes and thus to the pipe E.
The inner one H of the concentric pipes is continued, and passes through a
second stuffing box into a chamber L into which it opens. This chamber L is in
communication with the second lubricant chamber from which lubricant may
thus be led into the pipe D.
Of the two openings or channels F, G, in the casing C, it will be seen that one F,
communicates with the channel or opening M in the crank pin. This channel M
is so formed as to lead lubricant from the casing C to the crank pin bearing. The
other channel, G, in the casing does not continue right through but leads to a
groove or recess formed on the outside through a suitable opening g, Figures 1
and 6. The groove or recess on the casing contains a hollow or recessed ring N,
with the interior of which a pipe O is in communication. The other end of the
pipe O is led to the cross head, slide blocks or the like. The ring N may be con-
veniently formed in two parts, which are held together when in use by a sleeve P
which is slipped upon them, or by an equivalent device. Q, Q indicate glands
or packings to prevent escape of the lubricant.
It will thus be seen that one lubricant may pass along the pipes H and D,
and the passages F and M to the crank pin bearing, while the other lubricant may
pass along the annular space between the two pipes H, J, into the pipe E and
thence through the channel G, opening g, ring N and pipe O to the cross head or
slide blocks.
To reduce the risk of the ring N being carried round with the casing and to
relieve any strain upon the pipe O, a bracket R may be employed secured to the
coupling rod S and attached at its outer end to the sleeve P or to the ring N, or
any equivalent device may be used.
As before explained when one lubricant only is required for the crank pin and
for the cross head or the like, the two pipes may be dispensed with and one only
need be employed, in which case it would communicate with both the ring N and
with the crank pin bearing.
In order to allow for inaccuracies or for wear the different pipes D, E and O
may be provided with telescopic packed joints at any convenient point or points.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. Apparatus for lubricating a crank pin and a cross head or the like, consisting
