COMPLETE SPECIFICATION.
A New or Improved Appliance for Attachment to the Rims of the
Wheels of Velocipedes and the like.
I, JOHN GERALD CHAMBERS, of No. 1, Holgate Terrace, Holgate Road, York, in
the County of York, Gentleman, 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:
This invention relates to a new or improved appliance for attachment to the
rims of the wheels of velocipedes and the like, and has for its object to provide
means whereby the speed of velocipedes & the like, whose wheels are fitted with
this invention may be greatly accelerated.
In carrying my invention into practice I provide on each or either of the wheels
of the velocipede or the like, one or more, but preferably two, knobs of metal
or other suitable substance, such knobs constituting small weights which are
attached to the rim of the said wheels, between the spokes, and in order that this
my said invention may be the more readily understood and carried into practical
effect reference is hereby made to the accompanying sheet of illustrative drawings
wherein:
Fig. 1 represents in section one of the knobs detached from the rim.
Fig. 2 represents partly in section a portion of the rim of a wheel to which my
invention is to be fitted & in
Fig. 3 is shewn on a reduced scale, a cycle wheel fitted with my invention.
Referring to the drawings, in which like letters of reference indicate corre-
sponding parts throughout, a is the rim of a wheel through which a screw b is
screwed and c is a knob of convenient construction, having a tapped hole or
recess d in its upper end which hole or recess is adapted to take on to the screw b
& thus become attached to the rim a.
Interposed between the end c¹ of the knob c and the rim a a rubber or other
such washer e may be provided for the purpose of keeping water and dust from
passing through the tapped hole in the rim & thus damaging the tyre.
It will be understood that I do not confine myself to the precise shapes and
sizes of the knobs shewn but may vary the same without departing from the spirit
of my invention.
From the foregoing description taken in conjunction with the drawings, it is
obvious, that the weight of the knobs concentrated at certain points on the rim
of a wheel will, by virtue of centrifugal force, tend to accelerate the speed of the
wheel when once the same is driven.
Having now particularly, described & ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The new or improved device for attachment to the rims of the wheels of
velocipedes and the like substantially as and for the purpose herein before de-
sarihed & shewn

page_text: 2. In means for accelerating the speed of velocipedes and the like the knobs
fitted to the rims of the wheels in any convenient manner substantially as here-
inbefore described and illustrated.
