IMPROVEMENTS IN VELOCIPEDES
Year: 1884

page_text: I EDWARD CARL FREDERICK OTTO of Peckham in the County of Surrey, Civil
Engineer do hereby declare the nature of said invention for "IMPROVEMENTS IN
VELOCIPEDES " to be as follows:-
In a patent application bearing even date with this my patent application,
I have described a mode of constructing and applying balance gear for driving and
steering purposes and a contral swinging frame for enabling the rider to assume the
most favorable position for the work, to a bicycle on the general plan of my Otto
bicycle.
Now according to this present invention I apply the balance gear and the
clutches and brakes and the central swinging frame to tricycles and other
multicycles in order to gain similar advantages as those stated in my other
application. In such velocipedes where a balance gear is employed I use clutches
and brakes in the manner described in my other application and actuate them
from the ordinary steering handle part for either driving or steering purposes.
I may also in connection with the said clutches and brakes, apply the aforesaid
central swinging frame upon the road wheel axle. In the case where the clutches
and brakes as well as the swinging frame are used, the handles for the aforesaid
clutches and brakes may be arranged on the swinging frame and in the case where
the swinging frame is not used the handles for the brakes and clutches may be
arranged on the present steering handle part. When effecting the steering by
means of the balance gear, the gear in connection with the front or hind steering
gear may be dispensed with and the use of the present front or hind steering wheel
as a steering wheel discontinued and such wheel is then made to assume any
position freely, but it is by preference fitted with a spring or springs for somewhat
steadying it. For single driver tricycles I employ my aforesaid central swinging
frame the motion from the crank shaft being transmitted to the driving wheel
In such tricycles in which no balance gear is used but where clutches and
chains or double chains are used for making a double driver or where the driving
gear is not in the centre I ft my swinging frame intermediately between the
wheels and with its fulcrum in or near the centre line of the wheel axle.

Civil Engineer do hereby declare the nature of said invention for "IMPROVE-
MENTS IN VELOCIPEDES' and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
"
In a patent application bearing even date with this my patent application
I have described a mode of constructing and applying balance gear for driving and
steering purposes and a central swinging frame for enabling the rider to assume the
inost favourable position for the work, to a bicycle on the general plan of my Otto
bicycle.
Now according to this present invention I apply the balance gear and the
clutches and brakes with or without the central swinging frame to tricycles and
other multicycles in order to gain similar advantages as those stated in my other
application. With the swinging frame I use pedals with footstraps, though the
latter are not shown in the drawings.
Figure 1 is a side view of a central driver tricycle provided with balance gear,
clutches and brakes arranged in the central part of the axle as described and shown
in my aforesaid patent Specification but without the Otto swinging frame, the
pedal crank A being on the contrary mounted in a bearing forming part of the
frontal bone or frame B of the machine. The brakes O and P and Q and R
described with reference to Figures 4 to 8 of the said specification, are however in
this case operated from gear on the steering handle as shown more fully in the
cross sectional view Figure 2, and the detail view. Figure 3 such steering handle
gear being described in the specification of my patent No 5433 of 1883 but for the
purpose of this present invention the bevil gear is omitted and replaced by lever
gear.
The two outer or steering brakes P and O are operated by a lever a fixed on
each side of the sleeve b the brake bands being connected thereto by ball and
socket joint shown in section at Figure 3. The two inner or retarding brakes Q
and R are operated from a bell crank lever c, d on each side which by the link e
are connected to the sleeve f which can slide up and down but so as not to turn on
the aforesaid sleeve b. The sleeve f is operated by the handles g g as in the patent
specification No 5433, of 1883. The third wheel which may be a front wheel Fas
shown is arranged to assume any position freely according to the position which
the steering or course of the machine might cause it to assume but so as not to act
as a steering wheel. A spring G is by preference fitted to its fork for somewhat
steadying it relatively to the frame of the machine.
Figure 4 is a sectional side view of a central driver tricycle fitted with the same
balance gear, clutches and brakes, but with my Otto swinging frame applied in the
centre of the machine and with the various handles for operating the brakes and
clutches arranged on a steering handle standard on the frontal bone of the machine
in the same manner as just described with reference to Figures 1 to 3.
Figure 5 is an end view showing the swinging frame T and the balance gear
with brakes O P Q and R. The frame B with frontal bone is mounted on the

page_text: axle, and so also the swinging frame T.
The parts for operating the brakes are
arranged as described with reference to Figures 1 to 4. This tricycle is also shown
with a voluntary front wheel (or it might be a hind wheel).
Figure 6 is a sectional side view of a central driver tricycle fitted with the same
balance gear, clutches and brakes and with my Otto swinging frame T applied in
the centre of the machine, but having the various handles for operating the clutches
and brakes arranged on a steering handle standard on the swinging frame T which
for this purpose is provided with a front extension E. This tricycle is shown fitted
with a voluntary front wheel (or it might be a hind wheel).
Having now particularly described and ascertained the nature of my said.
invention and in what manner the same is to be performed I declare that what
I claim is
1. In tricycles and other multicycles having an Otto swinging frame or not, the
employment of any balance gear in combination with suitable clutches and brakes,
all so arranged that the advantages of a true double driver are obtained while
the brake power applied to retard the inner wheel in turning a curve is trans-
ferred as an effective driving power to the outer wheel, and also so that a straight
course is normally obtained when the steering brakes are not applied, while the
third wheel or other additional wheels are free to assume any position which the
direction of the vehicle may cause it or them to assume.
2. The combination of parts forming the tricycles illustrated in the accompanying
drawings.
