Improvements in Centrifugal Lubricators for Crank Pins.”
I HENRY NIELD BICKERTON, of 6 Richmond Street Ashton-under-Lyne, Gas
Engineer, do hereby declare the nature of this invention to be as follows:-
The improvements relate to centrifugal lubricators for crank pins, and have for
object to lubricate the crank pin and adjacent frictional surfaces, in a simple and
effective manner.
To accomplish this and to carry out my improvements, I form a ring, flange or
circular projection, either upon a convenient part of one of the crank shaft bearings,
or independently thereof; or it may be that I utilise an ordinary projection of the
bearing for the purpose to be hereinafter described.
To this ring, flange or projection I cause to be conducted, by any suitable means,
oil or other lubricant, which may be supplied from the residue of oil out of one of the
bearings, or from an oil-cup or other source.
In contact, or nearly in contact, with this flange or projection, I provide a rod,
wire, tube, chain or other connection, which I carry along and about, or through, one
of the crank arms, to the crank pin, where it terminates in manner as may be found
most suitable to the arrangement of the contiguous parts.
As the crank revolves, the rod, wire, tube chain or connection is pushed or trailed
round the periphery of the flange or projection, or round a groove therein, and the
oil deposited thereon or therein is spread over the peripheral surface of such flange
or projection, or of its groove, and carried by centrifugal action along the rod, wire,
tube, chain or other connection to the crank pin, for lubricating purposes, as will be
readily understood.
Variations in detail may be made, such as in the design, material and method of
attachment or connection of the various parts, without departing from the
peculiar character of the invention.

"Improvements in Centrifugal Lubricators for Crank Pins.”
I, HENRY NIELD BICKERTON, of 6 Richmond Street, Ashton-under-Lyne, Gas
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 :—
The improvements relate to centrifugal lubricators for crank pins, and have for
object to lubricate the crank pin and adjacent frictional surfaces in a simple and

page_text: effective manner.
To accomplish this and to carry out my improvements, I form
a ring, flange, or circular projection, either upon a convenient part of one of the crank
shaft bearings, or independently thereof; or it may be that I utilise an ordinary
projection of the bearing for the purpose to be hereinafter described.
To this ring, flange, or projection, I canse to be conducted, by any suitable means,
oil or other lubricant, which may be supplied from the residue of oil out of one of the
bearings, or from an oil cup or other source.
In contact, or nearly in contact, with this flange or projection, I provide a rod,
wire, tube, chain or other connection, which I carry along and about, or through, one
of the crank arms, to the crank pin, where it terminates in manner as may be found
most suitable to the arrangement of the contiguous parts.
As the crank revolves, the rod, wire, tube, chain or connection is pushed, or trailed,
round the periphery of the flange or projection, or round a groove therein, and the oil
deposited thereon or therein is spread over the peripheral surface of such flange or
projection, or if its groove, and carried by centrifugal action along the rod, wire, tube,
chain or other connection to the crank pin, for lubricating purposes, as will be readily
understood.
But that the improvements may be better understood, I will, with the aid of the
accompanying drawings, proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an end view and Fig 2 a side elevation, partly in section, of a crank and
bearings provided with lubricating apparatus according to my improvements.
The same letters indicate corresponding parts wherever they occur.
In this illustration of one form of my improvements, the flange or circular
projection a is shown as a part of the bearing a, in one of the crank shaft journals b.
This circular projection is provided with a recess at a², to which the lubricant is
conducted. by means of a pipe g, from any convenient or usual source not shown in
the drawings; and from which recess such lubricant may find its way to the periphery
of the projection a¹, by gravity.
In contact, or nearly so, with the flange or projection a¹, is a channeled connection
c, attached by a bracket c¹ to the crank arm d.
As the crank revolves, this connection c is pushed or trailed around the periphery
of the flange a¹, and the oil is spread over the peripheral surface of such flange, and
carried by centrifugal action along the connection c to the passage d¹ in the crank
arm d, which passage extends to any desired point of lubrication such as e¹ in the
crank pin or neck e. Variations in detail inay be made, such as in the design,
material, and method of attachment or connection of the various parts, without
departing from the peculiar character of the invention.
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 :—
In centrifugal lubricators for crank pins, the employment of a connection moving
with the crank and in communication with the part to be lubricated, which connection
travels in contact, or nearly so, with a stationary or separate lubricant bearing surface,
for the purpose and in manner substantially as herein shown and described.
Dated this 11th day of November 1897.
