page_text: I, HENRY NIBLD 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 gas and oil ongines, and have for object the attainment
of high speed with little noise, and with self lubrication of the more important
moving parts.
To effect this and to accomplish my improvoments, I construct and combine the
various parts of the engine in a special and peculiar manner as hereinafter described,
and such construction and combination is applicable to horizontal engines and to 9000
vertical engines as have the cylinders thereof inverted.
In the first place I enclose the principal working parts of the engine by a mun
casting of such a form as will completely or almost completely enshroud or cover in
such working portions. I also construct such main oasting with an oil well in the
lower portion thoreof, into which the crank can dip for self lubrication at each
revolution of the engine; whereby oil is also thrown up and self lubrication of other
working parts inay thereby be effected. Combined with this arrangement I employ
an automatic air and gas valve, thus dispensing with the necessity for cams. The
governor is a tappet or pondulum governor which I cause to be carried by the exhaust
valve lever, which exhaust valve lever is actuated by an eccentric pin, thus dispensing
with cams for this purpose also. I arrange the connecting rod with long bolts
passing from end to end, in such manner as to secure the caps at both onds at once.
These, and by preference all other caps on the shaft, I set up in the first place by
springs and hand nuts, and afterwards hold the same in position by clip nuts by
preference, although other locking devices may be employed for this purpose. I also
prefer to extend the crank shaft bearings into the interior of the main casting, by
which means I am enabled to cut away a portion of the upper surfaces of such
bearings, and suspend upon the portions of shaft thus exposed, rings, which by
extending into the oil well before named, will form a complete self lubrication of the
bearings when required.
By these means a compact self lubricating and comparatively silent engine is
obtained which can be run at a very high speed.
Variations in detail may be made, such as in the shape and design of the various
parts, the materials of which they are composed, without departing from the peculiar
character of the invention.

page_text: improvements in Gas and on Engines.
I, HENRY NIELD BIOKERTON, 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 gas and oil engines, and have for object the attainment
of high speed with little.noise, and with self lubrication of the more important
moving parts.
To offect this, and to accomplish my improvements, I construct and combine the
various parts of the engine in a special and peculiar manner as hereinafter described,
and such construction and combination is applicable to horizontal ongines and to
such vertical engines as have the cylinders thereof inverted.
In the first place I enclose the principal working parts of the engine by a main
casting of such a form as will completely or almost completely enshroud or cover in
such working portions.
I also construct such main casting with an oil-well in the lower portion thereof,
into which the crank can dip for self lubrication at each revolution of the engine;
whereby oil is also thrown up and self lubrication of other working parts may thereby
be effected. Combined with this arrangement I employ an automatic air and gas
valve, thus dispensing with the necessity for cams. The governor is a tappet or
pendulum governor, which I cause to be carried by the exhaust valve lever, which
exhaust valve lever is actuated by an eccentric pin, thus dispensing with cains for
this purpose also; or the ordinary or centrifugal governor may be employed as shown
in the drawings annexed.
I arrange the connecting rod with long bolts passing from end to end, in such
manner as to secure the caps at both ends at once. These, and by preference all other
caps on the shaft, I set up in the first place by springs and hand nuts, and afterwards
hold the same in position by clip nuts by preferenco, although other locking devices
may be employed for this purpose. I also prefer to extend the crank shaft bearings
into the interior of the main casting, by which means I am enabled to cut away a
portion of the upper surfaces of such bearings, and suspend, upon the portions of
shaft thus exposed, rings which by extending into the oil well before named, will form
a complete self lubrication of the bearings when required.
By these means a compact self lubricating and comparatively silent engine is
obtained which can be run at a very high speed. 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.

a' are the crank shaft bearings, which are extended into the interior of the main
casting, while a' shows parts thereof cut away to expose the shaft c¹ and to enable
the rings to be suspended thereon so as to form a means of self lubrication of the
bearings.
By this combination, an exceedingly compact and silent engine is obtained, possess-
ing to a large extent the possibility of complete self lubrication.
Variations in detail may be made, such as in tho shape and design of the various
parts, and the materials of which they are composed, without departing from the
peculiar character of the invention.
Having now particularly described and ascertained the nature of iny said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In gas and oil engines the combination of nu enclosing casting, capable of
enshrouding the principal moving parts, with an oil-well in which the moving crank
can dip for automatic lubrication, and also with pendulous rings for lubricating the
crank shaft, which shaft is carried by bearings projecting within the enclosing casting,
together with the automatic valves, all for the purpose and in inauner substantially as
herein shown and described.
2. In gas and oil engines, the combination of the whole of the apparatus arranged
in the manner and for the purpose as herein shown and described.
