A communication to me from PIERRE MALVEZIN, of 24, Rue du Chalet, Bordeaux,
Caudéran, in the Republic of France, Engineer
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Chartered Patent Agents
and Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, 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, and accompanying drawing, that is to say:-
--
This invention has for its objects an improved construction and arrangement
of cycles, especially in the driving gear and the part of the frames connected with
it and in the steering gear.
The accompanying drawing is in illustration of the invention.
Figure 1 is a side view, showing the pedal axle in a definite position near the
rear driving axle, which is provided with a small toothed driving pinion b, (one
being shown at each end of the axle in Figure 2, which is a cross section). The
toothed pinion b gears with a corresponding internal toothed driving wheel a,
which is fixed upon the pedal axle, (as shown in Figure 3 in side view, on a larger
scale).
When the pedal cranks are set in action, the driving wheel of the cycle is made
to revolve in the proper direction.
The teeth of the internal toothed driving wheel a are fitted with rollers turning
upon pins, which can be changed when desired, and the teeth of the pinion b with
which they gear may be similarly fitted (as illustrated in Figure 4).
b
Or, the pinion may have teeth of the ordinary kind, as shown in Figure 5.
The bearings for the toothed wheels a and b, on both sides of the machine, are
arranged in parts of the frame at d, which are stayed against the weight of the
rider by two stays c, c¹.
The adjustment of the gearing together of the toothed wheels is rendered
possible by the easily slackened and adjustable bearings of the wheels band of the
driving wheel of the machine, in a slot in the part d of the frame, as illustrated
in Figure 3, the bearings being fixed by screws and nuts as shown.
Another part of the invention has for its object the variable adjustment of the
handle bar so that the handles are in a higher or lower, position, according to the
particular purpose for which the cycle is to be used, such as racing or road riding,
and to the convenience of the rider.
The method heretofore ordinarily used of drawing in or out the steering bar gives
a comparatively small variation in the position of the handles. By the present
invention, however, the handle bar is not only adjustable upon the steering bar
whilst riding, within wide limits, but the handles themselves are adjustable in any
desired position upon the handle bar.
In the accompanying drawing Figures 6, 7, 8, and 9 are in illustration of this
nart of the invention,

scale, Figure 8 a back view of Figure 7, and Figure 9 a horizontal section of
Figure 6.

The steering bar f surrounds the handle bar, and they are attached so that the
handle bar can be turned round' in the socket in which it fits, and can be adjusted
and fixed in any desired position; for which purpose the socket on the handle bar
is made with a circumferential slot having teeth on one edge, into which fits a
pall or catch g contained in the tubular handle bar and pressed against the teeth
by a spring (Figure 9).
The change in the position of the handle-bar is. effected by pressing upon a
suitable handle or hook which withdraws the catch g by means of a wire or cord
passing through the handle bar. When the catch has been thus released, the
handle bar can be turned into the desired position, and it is then fixed by releasing
the handle and allowing the catch g to enter a fresh notch.
In a very similar way the position of the handles themselves upon the handle,
bar can be varied, by making them turn upon a centre (as shown in Figures 6
and 8). The handle is held in position by a spring catch upon it which fits into a
series of notches upon the end of the handle bar. By pressing upon a handle or
hook e the catch is withdrawn and the handle can be turned into a fresh position,
where it is held by releasing the catch. In Figure 6, different positions of the
handle bar and the handles are shown in dotted lines.
Having now particularly described and ascertained the nature of the said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1.—In cycles, the internal toothed driving wheels fixed upon the pedal axle,
and gearing directly with corresponding toothed pinions, upon the back driving
wheel of the cycle, substantially as described and illustrated.
2. In cycles, the methods of instantly altering and fixing the position of the
handle bar, and the handles, whilst riding, substantially as described and illus-
trated.
