We, FRANCIS WILLIAM CROSSLEY of Crossley Brothers, Limited, Openshaw,

Engineers, do hereby declare the nature of this invention to be as follows
This invention relates to improved means of lubricating the rapidly moving parts
of machinery.
In applying our invention we employ any kind of oil cup or receptacle having
suitable means for regulating the delivery of the oil, such as a worsted wick,
The

oil is led by a nozzle or pipe to a suitable position for being caught up by an
attachment to the moving part to be lubricated hereinafter called the receiver.
This invention consists of the special shape of this receiver which enables it to
receive the oil without throwing it off, though moving at a high speed. We are
aware that what are known as wiper lubricators of a somewhat similar construction
have commonly been in use with slowly running machinery but they have never
been so constructed as to enable them to be applied to high speed machinery.
When applied to lubricate, say, the crank pin of an engine the receiver may be
fixed on one of the crank pin brasses in such a manner that as the crank revolves
it passes close to, (say within one-sixteenth of an inch,) the end of the oil nozzle.
The part of the receiver which passes closest to the nozzle has an extended surface
which may be very slightly rounded and as it passes this touches the drop of oil
hanging from the nozzle, a small portion of oil adheres more or less to the extended
surface and so diverts the oil that it is caught in a following undercut groove which
surrounds the slightly rounded surface and is led from this groove by suitable oil
holes to the crank pin. In another arrangement the receiver may be fixed to the
side of the crank web and oil holes are drilled through the crank web and pin so as
to conduct the oil to the surface of the journal.
We wish it to be understood that this invention consists of the use of the extended
surface of the receiver which by means of capillary or adhesive attraction diverts
the oil so that it may be caught up by a following undercut groove at very high
speeds without throwing it off.
When applied to an engine which has to be reversed so as to run in either
direction the undercut groove must be at both sides of the extended surface. In
some instances the groove may be circular surrounding the extended surface which
being slightly rounded stands higher than the rest of the receiver.

page_text: We, FRANCIS WILLIAM CROSSLEY of Crossley Brothers Limited, Openshaw,
Manchester, and JAMES ATKINSON of Amherst, Fallowfield, Manchester,
Engineers, 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 relates to improved means of lubricating the rapidly moving parts
of machinery.
In applying our invention we employ any kind of oil cup or receptical having
suitable means for regulating the delivery of the oil, such as a worsted wick,
attached to or forming part of any convenient stationary part of the engine. The
oil is led by a nozzle or pipe to a suitable position for being caught up by an
attachment to the moving part to be lubricated hereinafter called the receiver.
This invention consists of the special shape of this receiver which enables it to
receive the oil without throwing it off, though moving at a high speed. We are
aware that what are known as wiper lubricators of a somewhat similar construction
have commonly been in use with slowly running machinery, but they have never
been so constructed as to enable them to be applied to high speed machinery.
To enable our invention to be clearly understood we append two sheets of
drawings, in which,
Sheet 1 represents the manner in which we apply our lubricator to one of the
brasses of a connecting rod connected to a crank pin; Fig. 1 being a side elevation,
and Fig. 2 an end elevation.
Sheet 2 represents an alternative method of lubricating a crank pin, the receiver
being fixed on the side of the crank web, the oil passing through a hole in the
crank pin to the bearing; Fig. 1 being a side elevation and Fig. 2 an end
elevation.
In the arrangement shown in Sheet 1 there is an oil cup A fixed in any con-
venient manner, having a nozzle B to which the oil is fed in any convenient
manner. The point of the nozzle B is shewn almost touching the receiver C in the
middle which has an extended surface, in this instance shown slightly rounded.
As the crank revolves the receiver C passes the nozzle point each revolution, and
an oil drop on the point would come into contact with the middle of the receiver C,
spreading more or less over the extended surface and so diverted downwards that
it is caught by a following undercut groove which is shown surrounding the slightly
rounded surface of the receiver. The oil is led from the undercut groove by
means of suitable oil holes, as shown, to the crank pin. The middle of the extended
surface is the part of the receiver C which always passes nearest to the point of the
nozzle B so that the drop of oil cannot be touched by any other portion of the
receiver C.
In the arrangements shown in Sheet 2 the receiver D) is shown fixed to the side
of the crank web, the oil is led from the oil pot E by the pipe F, the action being
the same as that described in connection with the arrangement shown in Sheet 1.
We wish it to be understood that this invention consists of the use of the
extended surface of the receiver in conjunction with a following undercut groove.
The drop of oil being diverted by means of capillary or adhesive attraction so
as to be caught by the edge of the undercut groove, though this edge passes
at a greater distance from the point of the nozzle, or pipe, which supplies the
oil than the extended surface does. The oil being led by suitable ducts to the
surface to be lubricated. We are thus enabled to lubricate the moving parts
of machinery at very high speeds.
In both the arrangements shown, the undercut groove is shown on both sides of

page_text: the extended surface, so that the engine could run in either direction. It will be
understood however that the undercut groove is only necessary on the following
side.
Reciprocating parts or irregular moving parts can be lubricated by constructing
the receiver suitably, as will readily be understood.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is.
1. In apparatus for conducting lubricating fluid to the moving parts of machinery
the employment of an extended surface for receiving the fluid and slightly diverting
it so that it may be caught by a following undercut groove and suitably conveyed
to the part to be lubricated, substantially as described and illustrated.
2. The general arrangement and construction of lubricating apparatus as described
and illustrated in Sheets 1 and 2 of the accompanying drawings.
