PROVISIONAL SPECIFICATION.
Improvements in Bicycles and Tricycles and like Vehicles.
PHILIP BELL Great Ryburgh Norfolk Smith do hereby declare the nature of
this invention to be as follows:-
Two cramp irons fixed on each wheel, to two of the steel spokes, at opposite
parts, and near to the rim of the wheel; to the central part of the cramp irons, is
attached a weight of about three quarters of a pound.
The cramp iron which is securely fastened by a thumb screw at one end,
braces two of the steel spokes of the wheel at about the distance of six inches from
the inside of the tyre; and at its central part a weight of about three quarters of a
pound is fixed, by one small bolt or screw; and to counterbalance the wheel,
another cramp iron and weight exactly similar is fixed in the same manner, at the
opposite part of the wheel so that a pair of them is attached to each wheel of
the bicycle or tricycle or like vehicle, and which as in all circular motion there is
a continual tendency on the part of the rotating body to recede from the centre of
rotation, it is this tendency which constitutes the centrifugal force, and in mechanics
and consequently in this invention its intensity is proved to be proportioned to the
square of the velocity with which the body move, or in plainer words, the faster
the machine is driven by the rider, the greater will be the centrifugal force
attained by the weight being fixed to the parts of each wheel as herein stated, as
the greatest power is to be obtained near the circumference; thus giving the rider of
the bicycle, or tricycle, or like vehicle, great assistance and ease in the working
of the treadles of the machine as well as to attain to a greater speed and of longer
duration.

COMPLETE SPECIFICATION.
Improvements in Bicycles and Tricycles and like Vehicles.
PHILIP BELL Smith Great Ryburgh Norfolk, 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:—
A weight of about three quarters of a pound applied to the two opposite parts of
each wheel, near or adjoining the inside of the rim of the same, preferably by being
attached to a cramp which is screwed to two of the wires or spokes of same.
This invention relates to facilitating the propulsion of bicycles and tricycles and
other like vehicles, with less exertion to the riders, propelling same, and also
increasing and maintaining speed of such machines with a minimum force applied
by means of centrifugal force obtained in the following manner. I provide a
weight attached preferably by a cramp to the spokes of the wheel, this weight will
be say about three quarters of a pound, and is fixed preferably to the central part
of this cramp, grasping it on both sides, and having a small screw passing quite
through, with a countersunk head which fits in level, and the part of the weight
extending farthest from the cramp will be the heaviest part, and will extend in the
direction of the rim of the wheel, and in close proximity to it, and curved, thus
resembling a segment of the rim or tyre. This cramp which in form somewhat
resemble the letter V will be of sufficient length to clasp two wires or spokes of
the wheel that are straight with each other, thus passing one of the wires or
spokes, and at the distance of about say five inches from the inside of the rim,

screws it firmly to the wire or spoke.
I provide a weight attached to a cramp as hereinbefore described, to the two
opposite parts of each wheel of bicycles and tricycles and like vehicles, that one
weight may counterbalance the other.
In a modification I attach the said weights of suitable form to the wheel rim on
the inside, in positions as hereinbefore described, by screws or equivalent attach-
ments. I prefer to make the weights, of cast iron or other metal.
I claim the sole right of applying weights to the machines herein named, and for
purposes herein stated.
I claim the right of option to make the said weights and cramps of any suitable
metal.
Dated this 3rd day of May 1893.
PHILIP BELL,
Great Ryburgh, Norfolk, Smith.
