I ARTHUR ALEXANDER BUCKHURST of St. George's Club Skating Rink, High.
Street, Wandsworth, London S.W. Skating Rink Proprietor 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 roller-skates and refers more particularly
to the wheels and the bearings of ball bearing skates.
My invention has for its object to provide an improved ball-bearing hub for the
wheels of roller-skates, whereby the wheels may be more readily secured to the hub
than heretofore.
In carrying my invention into practice I provide a hub of steel or other suitable
material furnished at one end with a flauge extending around its outer periphery.
The under surface of this flange is furnished with two pins. The hub being
passed through the central opening of the wheel, the flange drops into a recess,.
formed in the side of the wheel for that purpose, the two pins entering holes
likewise formed in the side of the wheel.
Upon the opposite side of the wheel is likewise formed a recess which accommo--
dates a recessed washer also furnished with two pins through which passes the
other end of the hub, this end being screw-threaded for the purpose of receiving a.
nut, which enters the recess in the washer before mentioned.
The hub is provided at either end with a cup-shaped recess in which are placed
the steel balls, and also with a central opening through which passes the spindle
upon which the wheel revolves. A semi-circular groove extending centrally
around the outer periphery of the hub is formed for the purpose of lightening the
same.
In the accompanying drawings,
Fig. 1 is a central section of a wheel fitted with my improved hub, Fig. 2 is a
plan of the same.
Like letters of reference indicate corresponding parts throughout the drawings.
The hub a is provided at one end with a flange b carrying upon its under surface
the pins c.
This hub is passed through a central opening in the wheel the flange b-
entering a recess m formed purposely, while the pins c also enter holes formed to
receive them as clearly shown in Fig. 1 of the drawings. Around the other end of
the hub and in a recess similar to m formed in the opposite side of the wheel w-
is placed a recessed washer provided upon its inner surface with pins c¹ entering
corresponding holes formed in the side of the wheel w. A nut g is screwed on the
screw-threaded end of the hub a and' enters the recess in the washer f as shown in
the drawings. The nut is provided with two holes or recesses h in which enter the
two arms of a fork or key used for removing or tightening the nut but not shown
in the drawings.
The hub is furnished at both ends with a cup shaped recess e in which the steel
balls are placed, the spindle upon which the wheel revolves passes through the
central opening o formed in the hub a. The outer periphery of the hub may be-
provided with a semi-circular recess d for the purpose of lightening the hub.

tion and in what manner the same is to be performed I declare that what 1
claim is :-

herein described and shown with reference to the accompanying drawings.
