We, GEORGE SMITH and EDWIN SMITH both of Nene Side Iron Works, Thrapston,
in the county of Northampton, Engineers and Iron Founders, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to provide an improved self-adjusting, anti-friction
roller bearing or plummer block for shafting, axles, loose pulleys, or for any like
purpose, the improved bearing requiring no lubrication; and our invention consists
in employing elastic rollers or cylinders, that is to say, rollers or cylinders made of
vulcanized india-rubber, woodite or other suitable elastic material. In practice we
find it advantageous to connect a number of our rollers or cylinders by a series of
links at each end thus keeping the rollers apart from each other and allowing of
adjustment to compensate for wear, or our elastic rollers or cylinders may be kept
apart by other suitable means such as by means of rings.
It will be obvious that our elastic rollers or cylinders may be made of metal or
other hard material coated with vulcanized india rubber or analogous elastic material.
Amongst the advantages of our improved bearings may be mentioned, that by the
use of our elastic rollers or cylinders, no lubrication of the bearing is required, and
that neither the shaft nor the bearing properly so called is affected by wear,
wear being confined to our elastic rollers or cylinders which it will be obvious can
be easily replaced by others when required.

page_text: We, GEORGE SMITH and EDWIN SMITH, both of Nene Side Iron Works, Thrapston,
in the county of Northampton, 'Engineers and Iron Founders, 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 object of this invention is to provide an improved self-adjusting, anti-friction
roller bearing for shafting, axles, loose pulleys, or for any like purpose, the improved
bearing requiring no lubrication; and our invention consists in employing elastic
rollers or cylinders, that is to say, rollers or cylinders made of vulcanized india-
rubber, woodite, or other suitable elastic material.
In practice we connect a number of our rollers or cylinders by rings which also
keep the rollers apart from each other.
It will be obvious that our elastic rollers or cylinders may be made of metal or other
hard material coated with vulcanized india rubber or analogous elastic material.
In order to enable our invention to be fully understood we will proceed to describe
how the same may be carried into practice by reference to the accompanying
drawing in which figure 1 represents an elevation half in section of a bearing or
plummer block provided with elastic rollers or cylinders according to our invention;
figure 2 is a plan of the same with half of the cover or cap removed. Similar
letters in both the figures represent similar parts.
A represents a plummer block and B the cap or cover of the same connected by
bolts CC and nuts D D in the usual manner; a, a, a, represent our elastic rollers
or cylinders made of vulcanized india-rubber, woodite, or other suitable elastic material,
which rollers or cylinders we have 'here shewn connected and kept apart by divided
rings b, b, at each end but which can be connected by other suitable means such as
by a series of links at each end; c, c, c, are the roller or cylinder spindles fixed in
the rings b, b; E is the shaft or axle running in our improved roller bearing, the
said shaft bearing on the rollers or cylinders a, a, a, whilst the latter rest and rotate
in the plummer block A.
We have for the sake of example illustrated our invention as applied to an ordinary
plummer block, its application to other descriptions of bearings will be understood
without further description.
Amongst the advantages of our improved bearings may be mentioned that by the
use of our élastic rollers or cylinders, no lubrication of the bearing is required, and
that neither the shaft nor the bearing properly so called is affected by wear, all wear
being confined to our elastic rollers or cylinders which it will be obvious can be easily
replaced by others when required.

page_text: Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that we do not claim
broadly the use of rollers but that what we claim is :-
1. The use in roller bearings of elastic rollers or cylinders substantially in the
manner and for the purposes hereinbefore described.
2. The improved roller bearing hereinbefore described and illustrated in the
accompanying drawing.
