page_text: on both sides and from which the motion is transmitted by the chains o to' the chain
wheels p mounted on the axle a, and thence to the front wheel.
The axle a is mounted in the usual manner in ball bearings.
The double ball bearings are adjustable on the bars c of the frame, and
are fixed by means of screws and nuts : By this means the chain wheels
can be suitably shifted with relation to one another in case of breakage or
slackness of the chain. The frame carrying the chain wheel driving gear can
be raised and lowered, and can be fixed by means of the rods g, and thus the
position of the crank shaft i with cranks k can be altered to suit the length of
the rider's legs.
As shewn in Figs. 2 and 3, the chain driving gear is arranged on each side of
the wheel whereby a more uniform distribution of power to the axle of the front
wheel is effected than is the case when the chain driving gear is arranged on one
side only. The wheel rim near the rider is covered over by a sheet metal guard t¹
arranged between the front wheel fork and the frame.
The saddle is arranged considerably further back and lower than in ordinary
high bicycles, so that shooting forward over the handles is prevented; and the front
wheel can be made much larger than usual, whereby a greater speed can be obtained
with safety. Also, riding is made much easier, as the weight of the rider is distributed
between both wheels. Since the hind wheel is always more strained than the front
wheel, and as in consequence of the favourable position of the saddle, mounting,
even in the case of a very large hind wheel, is not difficult, it is advantageous to
have the hind wheel as large as possible.
As in consequence of the rearward position of the saddle, the steering bars as
ordinarily arranged would be at too great a distance from it, the steering bar is
either removed from the fork head q and placed further back, or it is prolonged
- rearwardly as far as required.
In the first case, a vertically rotary pin u is fixed on the backbone of the
bicycle behind the fork head by means of a clamp (Fig. 6) and upon the square
upper end of said pin u the steering bars (with alarm and brake handle) is fixed,
and upon the steering bars is placed a thin steel rod whose ends are connected
by means of iron wire links or small chains to the ends of a rod which is
mounted on the square portion of the fork head q, and runs parallel with rod v.
The brake spoon or brake lever we left in front of the fork head is connected by a
rod to with the brake handle w¹. By the means described the front wheel can be'
easily and properly steered and braked.

In place of the rods and v¹, there may be keyed on the pin u and on the fork
head chain wheel segments a¹ connected by a chain a (Fig. 7).
The steering bar may however be left on the fork head, in which case, the
steering handles are bent rearwardly and downwardly to the front of the saddle,
as shewn in Fig. 8; or a rearwardly projecting and downwardly. bent handle is
attached to the usual handle bar (Fig. 9) being provided with handles for steering.
as shewn.

In another arrangement the steering bar s is mounted in an arm (Fig. 10)
which is fixed to the end of the pin or to the head of the front wheel fork.
In the arrangement shewn in Fig. 1 the front wheel fork is bent rearwardly so
that the fork head can be located so near to the rearwardly shifted saddle that the
steering bar can be mounted direct on the head of the front wheel fork without any
intermediate connections.
Since the same gearing up of the driving wheels can be employed in high bicycles

page_text: sides and from which the motion is transmitted by the chains o to the chain wheels p
mounted on the axle a, and thence to the front wheel.
The axle a is mounted in the usual manner in ball bearings.
The double ball bearings are adjustable on the bars e of the frame, and
are fixed by means of, screws and nuts . By this means the chain wheels can
be suitably shifted with relation to one another in case of breakage or slackness
of the chain. The frame carrying the chain-wheel driving gear can be raised
and lowered, and can be fixed by means of the rods g, and thus the position of the
crank-shaft with cranks can be altered to suit the length of the rider's legs.
As shown in Figs. 2 and 3, the chain-driving gear is arranged on each side of the
wheel whereby a more uniform distribution of power to the axle of the front wheel
is effected than is the case when the chain-driving gear is arranged on one side only.
The wheel rim near the rider is covered over by a sheet metal guard arranged
between the front wheel fork and the frame.

The saddle is arranged considerably further back and lower than in ordinary
high bicycles, so that shooting forward over the handles is prevented; and the
front wheel can be made much larger than usual, whereby a greater speed can be
obtained with safety. Also riding is made much easier, as the weight of the rider
is distributed between both wheels. Since the hind-wheel is always more strained
than the front wheel, and as in consequence of the favourable position of the saddle,
even in the case of a very large hind-wheel, is not difficult, it is advantageous to
have the hind-wheel as large as possible.
As in consequence of the rearward position of the saddle the steering bars as
ordinarily arranged would be at too great a distance from it, the steering bar is
either removed from the fork head and placed further back, or it prolonged
rearwardly as far as required.
In the first case, a vertical rotary pin is fixed on the backbone t of the bicycle
behind the fork head q by means of a clamp (Fig. 6) and upon the square upper
end of said pin u the steering bars (with alarm and brake-handle) is fixed, and
upon the steering bars is placed a thin steel rod whose ends are connected by
means of iron wire links or small chains to the ends of a rod ¹ which is mounted
on the square portion of the fork head q, and runs parallel with rod v. The brake-
spoon or brake-lever we left in front of the fork head is connected by a rod w³ with
the brake handle. By the means described the front wheel can be easily and
properly steered and braked.
•
In place of the rods and ¹, there may be keyed on the pin u and on the fork
head % chain wheel segments connected by a chain 2 (Fig. 7).
The steering bar may however be left on the fork head, in which case, the
steering handles are bent rearwardly and downwardly to the front of the saddle,
as shown in Fig. 8; or a rearwardly projecting and downwardly bent handle
provided with handles for steering as shown in Fig. 9 is attached to the usual
handle bar.
ولا
In another arrangement the steering bars is mounted in an arm s (Fig. 10) which
is fixed to the end of the pin or to the head of the front. wheel fork.
In the arrangement shown in Fig. 14 the front wheel fork is bent rearwardly, so
that the fork head can be located so near to the rearwardly shifted saddle that the
steering bar can be mounted direct on the head of the front wheel fork without
any intermediate connections.
Since the same gearing up of the driving wheels can be employed in high bicycles
provided with these improvements, as in low bicycles, the speed can be considerably
increased without rendering the bicycle unsafe.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A bicycle of the type herein referred to, wherein the pedal cranks are
mounted on axles ; located hrabind the axle of the front wheel and
geared to

page_text: the latter by means of chain wheels and endless chains, the bearings of the said
axles being made adjustable on a frame such as bed that is arranged to surround
the rear part of the front wheel and is capable of rotary movement about the axle
thereof, the said frame being connected with the fork of the said wheel by means
of side rods such as g, in such a manner that the distance between the said frame
and the saddle, which is arranged somewhat to the rear of the front wheel, can be
adjusted substantially as described and shewn.
2. In bicycles constructed as referred to in the preceding claim, the arrange-
ments of steering bar substantially as hereinbefore described with reference
respectively to and shewn in Fig. 6; in Fig. 7; in Fig. 8; in Fig. 9; and in
Fig. 10 of the drawings.
