An Improvement in Lubricating Apparatus.
We, CHARLES HIBBERT BERRY, Engineer, of 16 Haslington Street, Moss
Side, Manchester, and JOHN SNOWDON Junior, of Westferry Road, Millwall, in
the County of London, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
In many cases where lubricant of a more or less greasy nature is employed for
bearings and other rubbing surfaces, it is necessary to distribute the lubricant by
separate pipes or passages to different parts of the rubbing surface or to different
surfaces. This invention relates to means of effecting equal distribution of the
lubricant to these different parts. For this purpose by means of a piston in a
cylinder worked by a ratchet and pawl or otherwise we force the lubricant into
a main pipe or channel from which pipes or passages branch off to the various.
parts to be lubricated. We make the inlet mouths to these pipes or passages of an
area so small in comparison with that of the main pipe or channel that there is
always in it a higher pressure than in any of the branch pipes or passages
themselves. We prefer to apply to the main pipe or channel a pressure gauge so
that an attendant can always see that the proper pressure is maintained.
passage from the cylinder to the main pipe or channel we provide a check valve to
prevent return of the lubricant when the piston is withdrawn for the purpose of
recharging the cylinder.

COMPLETE SPECIFICATION.
An Improvement in Lubricating Apparatus.
We, CHARLES HIBBERT BERRY, Engineer, of 16 Haslington Street, Moss
Side, Manchester, and JOHN SNOWDON, Junior, of Westferry Road, Millwall, in
the County of 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 following statement :-
In many cases where lubricant of a more or less greasy nature is employed for
bearings and other rubbing surfaces, it is necessary to distribute the lubricant by
separate pipes or passages to different parts of the rubbing surface or to different
surfaces. This invention relates to means of effecting equal distribution of the
lubricant to these different parts, as we shall describe referring to the accompanying
drawing which is a section partly in elevation of appliances according to our
invention for this purpose.
By means of a piston P in a cylinder C, worked by ratchet and paw or
otherwise, we force the lubricant into a main pipe or channel A from which pipes

page_text: or passages B branch off to the various parts to be lubricated. We make the inlet
mouths D to these pipes or passages of an area so small in comparison with that of
the main pipe or channel A that there is always in it a higher pressure than in any
of the branch pipes or passages B. We prefer to apply to the main pipe or
channel A a pressure gauge E so that an attendant can always see that the proper
pressure is maintained. This gauge consists of a piston urged down by a spring,
the piston-rod projecting through the top of the gauge so that the height of the
piston can be seen. When the indicators are in positions where they cannot easily
be seen, their stems may be connected to cords passing over pullies and working
indices in convenient positions. In the passage from the cylinder to the main pipe
or channel A we provide a spring check valve V to prevent return of the lubricant
when the piston P is withdrawn for the purpose of recharging the cylinder C.
For the valve, a cock may be substituted.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In lubricating apparatus having a main pipe or channel from which branches
lead to different parts to be lubricated, contracting the mouths of these branches,
substantially as and for the purpose set forth.
2. Providing the main pipe or channel with pressure gauges for the purpose set
forth.
3. In combination with the supply cylinder a check valve for the purpose set
forth.
