PROVISIONAL SPECIFICATION left by the said William Phillips Thompson

WILLIAM PHILLIPS THOMPSON of the Agency for Foreign Patent Solicitors,
6, Lord Street, Liverpool, in the County of Lancaster, and 323, High Holborn
in the County of Middlesex, Civil Engineer. "IMPROVEMENTS IN ANTI-FRICTION
BEARINGS FOR SHAFTS, SPINDLES AND THE LIKE."-A communication to me from
abroad by Etienne Salomon and Edmond Armant, both of the City of Montreal in
the District of Montreal and Province of Quebec in the Dominion of Canada.
This invention relates to improvements in bearings and journals for shafts of
steam-boats, drilling machinery, turbine wheels, screw jack heads, waggon axles,
lathe points, and all shaftings and moving parts of machinery whether the same be
arranged to work horizontally, diagonally or vertically.
Its object is to provide a bearing which shall be perfectly solid and steady while
the shaft, etcetera, is moving not liable to any but a very slight wear on account
of those surfaces which are exposed to friction being reduced to a minimum, and
capable of ready adjustment to compensate for such wear, besides being simple and
inexpensive in construction and specially designed and arranged to either wholly
do away with a lubricant, or greatly lessen the quantity of same.

page_text: The invention consists in the combination with a revolving shaft provided with
an enlargement or collar, and a suitable framework, of a sleeve surrounding said
shaft and screwed to part of said framework so as to be capable of adjustment,
and a suitable number of round balls of steel or other suitable hard material
arranged between the frictional surfaces of the collar, or enlargement, on the shaft,
and the screwed sleeve.
A lubricant may be dispensed with altogether by having balls or rollers at every
frictional point or those parts subject to very little wear may be lubricated from
an oil cup in any approved manner.
For horizontal shafts for steam-boats, and like purposes it is preferable to cast
a bed-plate with one or more upright standards, into which are screwed hollow
sleeves, through the centre of which the shaft passes. On said shaft is rigidly
fixed by any suitable means a collar for each screwed sleeve, or one between two,
and the edges or ends of both collars and sleeves preferably provided with
annularly grooved wearing plates between which the round balls are placed.
In vertical bearings the wearing plates may be omitted and the sleeve arranged
to screw around the outside of the projection from the frame.
The wearing plates may also be omitted from the horizontal bearing and grooves
be formed for the balls to work in on the collars and sleeves themselves or the
enlargement may be omitted and the groove put on the end of the shaft.
A set screw may also be used to hold the screwed sleeves firmly in place after
they have been set and to prevent any backward turning of the same, and one or
more of these screws may be used at will in both the horizontal, vertical, and
diagonal bearings, or any other device may be substituted therefor if necessary.
If desired both the ends and sides of the shaft may be provided with anti-
friction balls, or rollers, or when required both upper and lower surfaces may be so
provided.
The main feature of the invention is the means for adjusting ball bearings so as
to compensate for wear.
