IMPROVEMENTS IN MEANS OR APPARATUS FOR REDUCING FRICTION
Year: 1885

page_text: I, WILLIAM JOHN BREWER, C.E. of 2, Victoria Mansions, Westminster, do
hereby declare the nature of my invention for "IMPROVEMENTS IN MEANS OR
APPARATUS FOR REDUCING FRICTION," to be as follows:-
My invention relates to a mode of or arrangement for reducing the friction of
the wheels of vehicles on their axles and of revolving journals generally in their
bearings and of the rubbing parts of machinery and consists as applied to the
wheels of vehicles or to revolving journals in the employment of a number of
antifriction rollers of any known type, surrounding the axle or journal, said rollers
or balls being fitted to inner side of axle box near shoulder of axle, and at outer
end near the nut or the nose of axle, the centre of said axle thereby being free
from friction said centre being covered with a cloth-jacket, to retain oil or other
lubricant, and for the purpose of applying the necessary oil I fix an oil cup in any
convenient part of the nave or stock of the wheel, first providing a channel
communicating with inner side of axle box and in a direct line with the rollers
at shoulder and that part of the cloth-jacket near the said rollers.
As an alternative arrangement I may fit in place of rollers at the nose or end of
axle a circular or other wellknown surface-bearing in axle-box. The end of my
axle box may be constructed with screw thread-or other suitable and well known
means, so as to be detached if necessary, for the purpose of examining the rollers
or bearing-surfaces.
At inner side of axle box, near shoulder of axle, in centre of bearing of rollers,
I supply a recess or chamber to contain a supply of lubricant. Sides of said
chamber, may be moveable to allow of removal and renewal in case of wear.
To further increase safety of wheel attachment and to assist the bearing on the
nuts at nose of axle, I form my axle box with a flange on inner end near collar of
axle and of same or any suitable diameter as said collar, these two being joined
together by a circular ring U shaped and embracing both the collar on axle and
flange on axle box, also forming an extra protection against the entrance of dirt
or grit.

I WILLIAM JOHN BREWER 2 Victoria Mansions Westminster S.W. Civil Engineer
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, reference being had to the accompanying drawing which
shows a Sectional view of my Improvements:—
My Invention relates to a mode of or arrangement for reducing the friction of
the wheels of vehicles on their axles and of revolving journals generally in their.
bearings and of the rubbing parts of machinery and consists as applied to the
wheels of vehicles or to revolving journals in the employment of a number of
anti-friction rollers a of any known type surrounding the axle or journal b said
rollers or balls being fitted to inner side of axle box near the shoulder c of axle b
and at the outer end near the nut or the nose of axle d, the centre of said axle
thereby being free from friction, said centre being covered with a cloth jacket e to
retain oil or other lubricant, and for the purpose of applying the necessary oil I fix
an oil cup in any convenient part of the nave or stock of the wheel. First
providing a channel communicating with the inner side of axle box and in a direct
line with the rollers at shoulder and that part of the cloth jacket e near to said
rollers a.
As an alternative arrangement I may fit in place of rollers at the nose or end
of axle a circular or other well known surface bearing-The inner side of axle box,
I supply a recess or chamber to contain a supply of lubricant. To further increase
safety of wheel attachment and to assist the bearing on the nuts at nose of axle
I form my axle box with a flange on inner end near collar of axle and of same or
any suitable diameter as said collar these two being joined together by a circular
ring U shaped f and embracing both the collar on axle and flange on axle box,
also forming an extra protection against the entrance of dirt or grit.
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) The combination of arrangements of rollers or balls a surrounding the axle
or journal b arranged as and for the purpose described.
(2) The cloth jacket e to retain oil or other lubricant to lubricate the axle or
journal 6 as and for the purposes described.
(3) The general arrangement of construction as shown and described.
