page_text: I, AUBREY FREDERICK SPENCER, of 24, York Villas, Brighton, in the County
of Sussex, Manufacturer of Mineral Waters, do hereby declare the nature of this
invention to be as follows:-
The invention has for its object improvements in anti-vibration wheels and is
applicable to wheels for vehicles, skates and for other purposes where it is
desired to avoid the communication of vibration and noise.
I will describe my invention as applied to a skate wheel. For this purpose
I form the rim of the wheel with a central annular web around the interior
thereof and I form on the exterior of the hub a screw thread which may be either
right or left handed.
I mount on the hub at one end a nut, in the centre thereof a centrally per-
forated disc or discs of india rubber, and then at the other end another nut;
the rubber disc or discs is or are of size to fit tightly over the hub and to fill
the space between the latter and the rim of the wheel and the nuts are formed
somewhat smaller in diameter than the internal diameter of the rim on cach
side of the annular web. These nuts are provided with means to enable them
to be screwed upon the hub until the rubber disc or discs is or are compressed
between them and the rim and hub and against the annular web in the interior
of the rim.
When using a single rubber disc it is formed with a peripheral groove to fit
the aforesaid annular web and in such case requires to be forced past such web
until the said peripheral groove is in line with the web, but when using two
rubber discs, one of such discs is placed on the hub from each end thereof so
that one disc shall be first placed against one side of the web and then the other
disc against the other side thereof. The said web acts to retain the rubber disc
or discs and the hub centrally thereof. If desired a washer may be placed
between the rubber disc or discs and the nuts.
The hub and spindle passing therethrough may be fitted with ball bearings
and dust caps or oil containers may be fitted over the ends thereof; these latter
may also act as lock nuts. The hub may however be provided with other kinds
of bearings.
In applying my invention to other classes of wheels, a similar arrangement
of parts to that above described will be employed but in some classes of wheels
the spokes or web will be connected to what is above referred to as the rim.
Instead of using solid rubber discs as above described flexible chambers formed
with a central hole and filled or partially filled with water or air may be employed
or I may use an inner chamber and an outer cover, the said chamber being pro-
vided with a filling nozzle and valve as in pneumatic tyres by which air or
water can be supplied to said inner chamber.
When employing a chamber filled or partially filled with water and no outer
cover, no valve will be required as the hole through which the chamber is filled

page_text: with water can be closed in any suitable way or if a tube is employed the tube
can be tied.

Improvements in Anti-vibration Wheels.
I, AUBREY FREDERICK SPENCER, formerly of 24, York Villas, Brighton, in the
County of Sussex, but now of 89, Louisville Road, Upper Tooting, in the County
of Surrey, Manufacturer of Mineral Waters, 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:-
The invention has for its object improvements in anti-vibration wheels and is
applicable to wheels for vehicles, skates and for other purposes where it is
desired to avoid the communication of vibration or noise.
I will describe my invention by the aid of the accompanying drawings in
which Fig. 1 represents a pair of skate wheels and the axle bracket showing half
in section and half in clevation and Fig. 2 is a section of the hub of a cart or
carriage wheel.
In both figures like parts are indicated by similar letters of reference.
I will first describe my invention as shown at Fig. 1 applied to a skate wheel.
For this purpose I form the rim a of the wheel with a central annular web a¹
around the interior thereof and I form on the exterior of the ends b₁ of the hub
or sleeve a screw thread which may be either right or left handed.
I mount on one end of the hub or sleeve ba nut c, nearer the centre thereof
I mount centrally perforated discs d of india rubber and at the other end of said
sleeve or hub I mount another nut c; the rubber discs d are of size to fit
tightly over the hub or sleeve b and to fill the space between the latter and the
rim a of the wheel; these discs are also formed with a circular rib around
their peripheries; between the nuts c, c¹ and the rubber discs d I place metal
washers which fit within the circular ribs of the discs d so as to centre
them on the hub or sleeve b, the holes in said washers e being slightly larger
than the exterior of the hub or sleeve so as to enable them to pass freely over
the same.
The nuts care provided with means, such as holes or flats, to enable them
to be screwed upon the hub or sleeve b until the rubber discs d are compressed
between them and the rim a and the hub or sleeve b and against the annular
web a¹.
One of such rubber discs d is placed on the hub or sleeve 6 from each end
thereof so that one disc shall be first placed against one side of the web a¹ and
then the other disc against the other side thereof. The said web acts to retain
the rubber discs and the hub or sleeve b centrally therof.
The hub or sleeve band the spindle f passing therethrough may be fitted
with ball bearings g and the external nuts & may be formed to act as dust caps
or oil retainers.
The hub or sleeve may however be provided with other kinds of bearings.
In applying my invention to other classes of wheels, a similar arrangement
of parts to that above described will be employed but in some classes of wheels

page_text: such as that shown at Fig. 2, the spokes h or web will be connected to what
is above referred to as the rim a which latter may be of wood.
In this latter example I have shown an additional nut ca on the outer end
of the hub or sleeve b, the outer nut c then serving as a lock nut. This extra
nut may also be used in the arrangement shown at Fig. 1 in which case the
dust cap nut c can be removed thereby enabling the ball bearing adjustment to
be attended to without interfering with the adjustment of the anti-vibration
arrangement.
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: -
An anti-vibration wheel comprising a rim or ring provided with an internal
annular web an externally screw threaded hub in the centre of said rim or ring,
a rubber disc placed on each side of the annular web and fitting closely the
exterior of the hub, a metal washer placed against the outside surface of each
rubber disc and a nut screwing on each end of the hub and forcing the metal
washers against the rubber discs so as to compress the latter and force it between
the various parts to insulate the hub from the external rim or ring substantially
as herein set forth.
