COMPLETE SPECIFICATION.
Improvements in Ball-bearings.
I, GEORGE HENRY GUARDILAM BRIGGS, 38, Rue de Pont Neuf, Le Houlme, Seine
Inferieure, France, Cloth Dyer, 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:
-
My invention relates to improvements in ball-bearing and the object is to
simplify the construction and render them adjustable and capable of easy repair
and replacement without interference with the arrangement of other parts. In
carrying my invention into effect I bore out the hub or bearing somewhat larger
than the diameter of the shaft or spindle carried by it. In this hub or equivalent
part I provide radial holes preferably four in number in each of which is inserted
a screw having a cupped inner end and between the cupped end and the shaft is
a ball resting on the shaft or spindle and free to run in the cupped cnd of the
screw. Each screw is axially bored allowing the balls to be lubricated and suit-
able cups or caps may be provided for introducing the lubricant. In order to
more clearly show the nature of my invention I make reference to the accom-
panying drawing which shows a cross section. a is the hub or bearing bored
out to a somewhat larger diameter than that of the shaft or spindle b.
radially bored holes in which are inserted the screws & having the cupped inner
ends c.
In these cupped ends work the balls f on which rests the shaft or
spindle b.
Through each screw d is the axial lubricating hole g which may be provided with
any suitable kind of cup h or means for the supply of the lubricant When it
is desired to prevent the longitudinal movement of the shaft a round bottomed
groove may be provided round it in which the balls f may run.
€ are the
If desired the screws may be distributed along the bearing or hub, instead of
all being arranged with their centres in a line surrounding the shaft or spindle.
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. Improvements in ball bearings the said improvements consisting essentially
in providing a hub bearing or equivalent bored out somewhat larger than the
diameter of the shaft or spindle which is to run therein, the said hub, bearing
or equivalent having radially bored holes preferably four in number each hole
being provided with a screw having a cupped inner end to receive a portion of
the surface of a ball situated between the cupped end and the surface of the shaft
or spindle running in the bearing or equivalent, arrangements being provided
for holding lubricant and axial holes in the screws for conveying it to the balls,
the whole substantially as described in the above specification and exemplified
in the accompanying drawing.
2. For preventing the longitudinal movement of shafts or spindles running in
ball bearings such as are the subject matter of the preceding Claim 1, the

page_text: provision of a groove or grooves round the shaft or spindle substantially as described
in the above specification.
