page_text: I, PATRICK ADIE of No 28 Southampton Buildings Chancery Lane in tho
County of Middlesex, seek leave to amend the specification of Letters Patent,
No. 11261 of 1884, as shown in red ink in the copy of the original specification
hereunto annexed.
My reasons for making this amendment are as follows:-The part proposed to
be disclaimed was not to be gathered from the Provisional Specification.

page_text: I, PATRICK ADIE of 15 Pall Mall in the County of Middlesex, Engineer, do
hereby declare the nature of my said invention for "IMPROVEMENTS IN
VELOCIPEDES" to be as follows:-
In the Specification to my Patent N° 5569 of 1883, I described a construction of
velocipodes consisting of two driving wheels of such large diameter that the seat!
-for-the driver could be arranged-below their common axis, which was driven from
a crank shaft below by means of pulleys-and-bands or other gearing.
In velocipedes constructed according to my present invention, Iretnin the
advantages of stability and case in running afforded by the above arrangement,
while I obviate the disadvantage inherent in driving very large wheels by means
of comparatively small cranks.
For this purpose, I provide, în addition-to-the-said_two_large_wheels, a central
wheel of comparatively small diameter, that is to say, somewhat smaller than the
_ordinary driving wheel of a bicycle, and which constitutes the driving wheel, while
the two large wheels-only-constitute_running_wheels, the driver's seat being
situated by preference somewhat below the level of the axis of the latter as before,
and over the top of the central driving wheel, which may be driven either directly
by treadles on its axis or by preference through speed increasing gearing from a
separato treadle shaft.
In the arrangement which I employ by preference, the large wheels are loose on
their axle which is bowed outwards and upwards, and carries at its middle a socket
in which the vertical axis of the fork to the central driving wheel is pivotted, the
seat being situated within the bowed part of the said axle and carried thereby.
The fork has angular extensions beyond the point where it rests on the axle of
the driving wheel, and on such extensions are mounted toothed wheels gearing
with pinions on the axle of the driving wheel and having the cranks and treadles
attached to their axes.

page_text: I PATRICK ADIE of Broadway Works Westminster late of 15 Pall Mall in the
County of Middlesex Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN VELOCIPEDES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
My front which is my driving wheel is exactly like that of the Bicycle with or
without gearing up. My following wheels are attached to either end of a contorted
axle, or double back bone as it might be called, made preferably of light steel
tube, bent so as to pass over, and on each side, of the driving wheel and rider The
two following wheels may either be attached to the ends of this tube or axle when
so arranged, or preferably to springs coming from the ends which are in such case
bent forward to give room for said springs. The following wheels being attached to
these springs by their centres in the geared up-arrangement I employ metal-bands
corrugated throughout or having an inside layer corrugated, such bands running
on light-wheels surrounded on their edges-by-corrugated-rubber-the-teeth-on-the
band-pitching-into the teeth on the rubber But that the nature of my invention
may be better understood I will proceed to describe the drawings annexed in both
figures of which the same letters are used to indicate like parts wherein they occur
Fig I shews the machine in side elevation Fig II in plan A is the front or driving
wheel with the usual Bicycle fork cranks &c B B are the following wheels
attached to either end of D either directly by bending D backwards and the points
outwards or preferably by the intervention of springs attached to the centres of B B
as drawn. D which is pivotted at G comes preferably over the rider, who sits on
the saddle S, and passes down on either side to B B. E, E, are guards to prevent
tilting which may or may not be used.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what
I claim is
The driving wheel exactly like the wheel of the bicycle with two following
wheels these on a bent axle or double back bone which passes down on either side
of the driving wheel and rider, substantially as drawn and described, Also-the
speed-increasing gearing as described-when-that-is-used.

In the Specification to my Patent N° 5569 of 1883, I described a construction of

For this purpose, I provide, in-addition to the said two large wheels, a central
wheel of comparatively small diameter, that is to say, somewhat-smaller than the
_ordinary driving wheel of a bicycle, and which constitutes the driving wheel, while
the two large wheels-ouly_constitute running wheols, the driver's seat being
situated by preference somewhat below the level-of-the-axis of the latter as before,
and over the top of the central driving wheel, which may be driven either directly-
by treadles on its axis or by preference through speed increasing gearing from a
separate treadle shaft.
In the arrangement which I employ by preference, the large wheels are loose on
their axle which is bowed outwards and upwards, and carries at its middle a socket
in which the vertical axis of the fork to the central driving wheel is pivotted, the

The fork has angular extensions beyond the point where it rests on the axle of
