page_text: I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35 Southampton Buildings, Chancery Lane, in the County of
Middlesex do hereby declare the nature of this invention (a communication to
me from abroad by Monsieur Carrette, père, of Roubaix in the Republic of France,
Engineer) to be as follows:-
This invention relates to bearings used for revolving shafts, and it has for its
object a novel method of making such bearings so that the lubrication of the shafts
is simply, effectively, and economically accomplished, especially where the shaft
runs at a high speed or is very heavy, or where the tension of belts or ropes is
liable to prevent the proper admission of the oil between the shaft and the bearing,
or where the oil does not cover the whole surface of the bearing and consequent
friction and seizing between it and the shaft are liable to take place.
The improved bearing consists of two separate parts, having a space between
them in which revolves a disc or wheel fixed upon the shaft the lower part of
which disc dips into an oil reservoir formed in the lower part of the bearing and
divided into three parts communicating with each other, the disc dipping into the
central one.
As the disc revolves it carries up with it a certain quantity of oil which is
caught and removed from the wheel by a double adjustable oil holder which
distributes it down two lateral channels, to the two separate bearings upon each
side of the disc. The oil which escapes from the bearings runs back into the
reservoirs below, whence it is again raised by the revolving disc, and so on
continuously.
The top of the bearing is provided with a moveable cover, through which
the action of the apparatus can be examined and adjusted, and oil added when
required.
By this invention little or no attention is required, and the automatic oiling of
the shaft and bearing continues as long as the reservoir contains sufficient oil.

page_text: COMPLETE SPECIFICATION,
Improvements in Lubricating Bearings.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex do hereby declare the nature of this invention (a communication to
me from abroad by Monsieur Carrette, père, of Roubaix, in the Republic of France,
Engineer) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and accompanying
drawing, (that is to say) :-
This invention relates to bearings used for revolving shafts, and it has for its
object a novel method of making such bearings so that the lubrication of the shafts
is simply, effectively, and economically accomplished, especially where the shaft
runs at a high speed or is very heavy, or where the tension of belts or ropes is
liable to prevent the proper admission of the lubricating material between the
shaft and the bearing, or where the oil does not cover the whole surface and edges
of the bearing and consequent friction and seizing between it and the shaft are
liable to take place.
The accompanying drawing is in illustration of the improved bearing, figure 1
being an elevation, figure 2 a transverse section, figure 3 a longitudinal section, and
figure 4 a plan.
The improved bearing consists of two separate parts, having a space between
*them in which revolves a disc or wheel B fixed upon the shaft the lower part of
which disc B dips into an oil reservoir A formed in the lower part of the bearing
and divided into three parts communicating with each other, the disc B dipping
into the central one.
As the disc B revolves it carries up with it a certain quantity of oil which is
caught and removed from the wheel by a double oil-holder C, the position of which
can be easily adjusted according to the size of the shaft, and the quantity of oil
which is to be supplied, and which distributes the oil down two lateral channels
shewn in figures 3 and 4, to the two separate bearings upon each side of the disc B.
The oil which escapes from the bearings runs back into the reservoirs A below,
whence it is again raised by the revolving disc B, and so on continuously.
The top of the bearing is provided with a moveable cover E, through which
the action of the apparatus can be examined and adjusted, and oil added when
required.
By this invention little or no attention is required, and the automatic oiling of
the shaft and bearing continues as long as the reservoir contains sufficient oil.
The apparatus may be made of any suitable materials, and may be modified
more or less in its details according to the circumstances in which it is to be

page_text: employed, but 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 :-
1. In apparatus for lubricating bearings, the disc B fixed upon the revolving
shaft, substantially as and for the purpose described and shewn.
2. In combination with the disc B, the distributing device C, arranged and
operating substantially as and for the purpose described and shewn.
