Improvements in Roller Bearings Applicable to Washing, Wringing,
and Mangling Machines.
We, WILLIAM SMITH, DAVID MARKS and ROBERT WATSON, all of Britannia
Iron Works, Keighley, Yorkshire, Machine Makers, do hereby declare the naturo
of this invention to be as follows, that is to say:-
It has for its object the construction of roller bearings applicable to the shafts of
the rollers used in washing, wringing and mangling machines, in a cheap yet
efficient form.
This is attained by mounting the rollers, that form the bearing, between two
metallic rings which are held a suitable distance apart by appropriate cross pieces.
These metallic rings together with their rollers are mounted in suitably formed
pedestals and pressure-blocks carried by the end frames of the machines (in case of
the pedestals which are in connection with the bottom roller of the machine, if
desired they may be formed on the end frame), in such a manner that the said rings
together with the said rollers may revolve around one common axis, while each of
the said rollers is also permitted to revolve independently around its own axis, so
that when the shaft of the machine roller, which is inserted in the opening in the
rings is revolved, the bearing rollers together with the metallic rings will revolve,
with the result well known. And by the bearing rollers being thus mounted between
the metallic rings, the pedestals and pressure blocks in which they revolve, and
which are carried by the end frames of the machine, may be of a simpler and
less expensive form than those heretofore employed.

We WILLIAM SMITH, DAVID MARKS and ROBERT WATSON, all of Britannia
Iron Works, Keighley, Yorkshire, Machine Makers 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, that is to say :-
It has for its object the production of roller-bearings applicable to the shafts of the
rollers used in washing wringing and mangling machines for well known purposes;
in a cheap yet efficient form.
In order that this invention may be more readily understood, we have hereunto
appended a sheet of drawings illustrative thereof, bearing figures and letters of
reference used in the following description.
Fig. 1 is a sectional side view of the parts forming said bearings. Fig. 2 is a top
view of said parts. Figs. 3, 4, 5 and 6 are detail drawings.
The object above set forth is attained by mounting the rollers a between the metallic
rings, which are held a suitable distance apart from each other by the cross
pieces c. Said rollers a being thus mounted by having their outer ends of a pointed
or conical form (see fig. 5) so as to enter and operate within suitably shaped hollows
or holes d made in the rings b b₁ (shewn in broken lines fig. 3). Instead of the
hollows & being formed in the rings 66, they may be formed in the end of the roller a
(see fig. 6), and conical projections d¹ may be formed on the ring b as will readily be
understood.
The rings 6 6¹ together with the rollers a are mounted in suitably formed pedestals e
(these pedestals e form pressure blocks when inverted as when used with the top
roller of the machine) which are carried by the end frame of the machine, so that the
rings together with the rollers a will revolve around one common axis which is
also that of the shaft f (on said shaft f being mounted the machine roller as will be
well understood), while each of said rollers a is also permitted to revolve independently
around its own axis, so that when the shaft is rotated, the rollers a together with
the rings 6 6 will rotate with the result well understood.
By the rollers a being mounted between the rings 6, the pedestal or pressure
blocks e in which they revolve, may be of a simpler and less expensive form than any
heretofore employed in connection with antifriction roller bearings. These pedestals
or pressure blocks e being simply formed with a semicircular hollow to receive the
rollers a as illustrated by figs. 1 and 2.

page_text: As will be seen each of the rings b 61 is made to operate on the outer sides of the
pedestal e in order to prevent any lateral movement of the rollers a.
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 what we claim is :
1. The rollers a formed with pointed or conical ends as set forth in combination
with the rings 6 6¹, cross pieces c and pedestals or pressure blocks e substantially as
and for the purpose specified.
2. The roller a having its outer ends formed of a pointed or conical shape or with
hollows of a similar shape formed therein in combination with the rings 6 b¹ having
conical hollows or projections formed thereon substantially as and for the purpose
specified.
