PROVISIONAL SPECIFICATION.
Improvements in Ball Bearings for the Axles of Tramcars and
Rolling Shafts of other Machinery.
We, THOMAS CONSTANTINE FAWCETT and THOMAS CONSTANTINE FAWCETT,
LIMITED, of The Whitehouse Engineering Works, Leeds, in the County of York,
Engineers, do hereby declare the nature of this invention to be as follows:-
In constructing a ball bearing for tramcars and other axles according to our
invention, we fix upon the shaft a shell or number of shells or sleeves and upon
these we place spherical balls but between each ball we place a washer or flat ring
for the purpose of preventing the balls rolling against each other and upon the
said balls we place other rings all of which are enclosed within a suitable box or
chamber and lubricant may be conveyed to the parts in any suitable and
convenient manner.

Improvements in Ball Bearings for the Axles of Tramcars and
Rolling Shafts of other Machinery.
We, THOMAS CONSTANTINE FAWCETT and THOMAS CONSTANTINE FAWCETT,
LIMITED, of The Whitehouse Engineering Works, Leeds, in the County of York,
Engineers, 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:-
In constructing a ball bearing for tramcars and other axles according to our
invention, we fix upon the revolving shaft, a shell or number of shells or sleeves
and upon these we place spherical balls but between each ball we place a washer
or flat ring for the purpose of preventing the balls rolling against each other and
upon the said balls we place other rings all of which are enclosed within a suitable
box or chamber and lubricant may be conveyed to the parts in any suitable and
convenient manner.
Such being the nature and object of our invention we will now proceed to
describe the same more fully and for that purpose make reference to the
accompanying drawings wherein :-
Fig. 1 is a cross section of an axle box provided with spherical balls adapted
for tramcars and to the shafts of other machinery.
Fig. 2 is an end elevation of same with the outer cover removed so as to
more clearly shew the internal parts. A represents the axle on which is mounted
a sleeve B.

page_text: This sleeve is made to revolve with the axle by means of a clutch C the ends a
of which clutch enter into the recess b formed in the outer end of the said sleeve
and also into an adjoining slot c formed in the end of the said axle A as clearly
shewn in the accompanying drawing. Upon the outer periphery of the sleeve B
we place any suitable number of spherical balls D but each series of said balls is
divided or kept separate from the adjacent series by means of a washer or flat
ring E which may or may not be connected to an annular ring or flange F so that
such said shaft A revolves carrying with it the spherical balls D, the friction
upon the shaft or upon the sleeve is reduced to a minimum. The whole of the
apparatus lodges or is confined within a box or chamber G and lubricant may be
supplied to the rotary parts in any suitable and convenient manner. The outer
end of the box or chamber G is covered in by a hinged lid H hinged upon a
fulcrum I being made secure at the top by a bolt and nut J.
By constructing and arranging ball bearings as herein described and illustrated
in the accompanying drawings the friction upon the axle is considerably lessened
and by the spherical balls being divided by the washers or rings E the said balls
cannot grind against each other or become locked as would be the case if these
washers or flat rings were omitted.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
.-claim is :-
In ball bearings having spherical balls the combination therewith of sub-
dividing washers or rings E all arranged and operating in the manner shewn and
herein described.
