PROVISIONAL SPECIFICATION.
Improvements in Bearings applicable for Carding and Scribbling
Machines and for other purposes.
I, WILLIAM HENRY BROUGHTON, of Prospect View, Cross Gates, Leeds, in
the County of York, Engineer, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to provide a bearing for the stripping rollers of
woollen carding and scribbling machines which will be self-lubricating and which
will need very little attention.
My invention consists essentially in forming the support for the bottom brass-or
the brass itself-box-shape to serve as a reservoir for oil or other lubricant and into
which depend one or more pieces of cane the upper ends of which are screwed into
holes in the brass, these pieces of cane forming the means for conveying the oil to
the neck of the bearing.
In carrying out my invention as applied to scribbling and carding machines I
affix to the standards which usually support the rollers and which are attached to
the rigid semi-circular framing a box-shaped casing which is preferably made
sufficiently large internally to surround the bearing brasses and collars of the roller
shaft. This casing is provided with lugs or strips to prevent the brasses moving
out of place and forms a reservoir for the lubricant. The bottom bearing brass is
made to fit the interior of the casing and is chambered out underneath. One or
more holes are drilled and tapped in this brass and into each of them is screwed a
piece of cane one end of which projects into the oil in the reservoir whilst the other
end is flush with the neck of the bearing. A top brass may or may not be
provided.
In operation and as the shaft revolves the oil is drawn through the pores of the
cane and forms a thin film round the neck of the brass. This continues so long as
the shaft revolves. Slots are made down the sides of the brass so that should the
oil get carried round in greater quantity than necessary it will flow back again into
the oil reservoir.
I would have it understood that I do not confine myself to the use of cane for
the purpose named as I might make use of a piece of tube open at each end and
packed with a number of pieces of wire through the interstices of which the oil
would flow to the neck of the bearing. Nor do I confine myself to the use of this
bearing in carding and scribbling machines as the same may be found useful for
many other purposes.

0 Improvements in Bearings applicable for Carding and Scribbling.
Machines and for other purposes.
I, WILLIAM HENRY BROUGHTON of Prospect View, Cross Gates, Leeds, in
the County of York, Engineer do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
5 ascertained in and by the following statement :-
The object of this invention is to provide a bearing for the stripping rollers of

page_text: woollen carding and scribbling machines which will be self-lubricating and which
which will need very little attention from those in charge of such machines.
My invention consists essentially in forming the support for the bottom brass-
or the bottom brass itself-box-shaped so as to serve as a reservoir for oil or other
lubricant and into which depend one or more pieces of cane the upper ends of
which are screwed or otherwise secured into holes formed in the bottom brass, the
said pieces of cane forming the means by which the oil is conveyed to the neck of
the bearing.
The invention will be fully described with reference to the accompanying
drawings which represent a bearing applicable to woollen carding machines and in
which Fig. 1. represents a longitudinal section and Fig. 2 a cross section.
In carrying out my invention as applied to scribbling and carding machines I
affix to the standards which usually support the rollers and which are attached to
the rigid semi-circular framing a box-shaped casing A. which is preferably made
sufficiently large internally to surround the bottom bearing brass B. or sometimes
both bottom and top bearing brasses B. and B' and collars c of the roller shaft C.
The casing or reservoir A. may be of any suitable shape and is usually constructed
in the manner shown with lugs strips or dividing pieces a which support the brasses
whilst the brasses themselves are provided with suitable projections or means such
as are commonly in use-such for instance as lugs 6-to prevent them rotating with
the shaft. The casing A serves as a reservoir for a liquid lubricant the partitions a
having holes by means of which the lubricant may fill the whole of the space below
the brasses.
The bottom brass B. is provided with one or more holes b¹ into which are
screwed or otherwise secured pieces of cane D. the lower ends of which depend
downward into the lubricant. A cap or cover A¹ may be secured by bolts 6" to
keep dust out of the casing if desired whilst the side walls of the casing may be
tapered as at c¹ so that any oil which escapes beyond the collars e may readily flow
back into the oil reservoir. To facilitate this thin plates C¹ may be adjustably
fixed on the ends of the bearing so that the oil will be prevented passing along the
roller shaft.
In operation the shaft C revolves and in consequence of a rarefaction of the air
at the upper ends of the pieces of cane D the oil is drawn through the pores of the
latter and is carried round the shaft in a thin film so long as the rotation of the
shaft continues.
Should the oil be carried round in greater quantity than is necessary for efficient
lubrication the excess of oil will escape at the ends of the brasses and flow
back into the oil reservoirs. It will thus be seen that the lubrication is automatic
and that so long as the shaft revolves and the supply of oil lasts lubrication will
also be efficient.
I would have it understood that although I have described a bearing applicable
for the rollers of carding engines, the details of such bearing may be altered in
any convenient way to adapt it to any purpose to which bearings are now put
without departing from the nature of my invention which principally consists in
the use of one or more pieces of cane or their equivalent to conduct the lubricant
to the bearing.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I wish it to be distinctly
understood that I am well aware that oil has been conducted to the necks of
bearings by means of fibrous matter in the form of wicks suspended in the oil but
such I do not claim. Neither do I claim the conducting of oil to bearings by
means of tubes, but I declare that what I claim is :-
1. The use of one or more pieces of cane or their mechanical equivalent for
conducting oil from a reservoir to the neck of a bearing substantially as herein-
before described.
2. A self lubricating bearing in which one or more pieces of cane are used to

page_text: conduct the oil from a reservoir to the neck of the shaft substantially as and for the
purposes described.
3. A self-lubricating bearing constructed and arranged substantially as shown in
the accompanying drawings and for the purpose described.
