IMPROVEMENTS IN THE STEERING APPARATUS OF TRICYCLES
Year: 1884

page_text: I HARRY THRESHER of Brixton Riso in the County of Surrey, Engineer do
hereby declare the nature of my Invention for IMPROVEMENTS IN THE STEERING
APPARATUS OF TRICYCLES, to be as follows:-
My Invention is for improving the steering of Tricycles that have the two
driving or steering wheels side by side-the rider sitting between them on a saddle
on the backbone.
Instead of steering with the handle bars fixed on the front frame carried by the
axle I place a socket on the backbone in front of the rider, this socket has a short
arin at the side a corresponding arm is fixed to the head of the Machine, these two
arms are connected by means of a link or in place of these arms a chain or steel
band might be used to make the connection.
The handle bar is fixed on the socket so that when the riders weight is entirely
on the treadles which are carried by the front frame and axle the steering will be
effected from the backbone in the same way as if the rider was sitting upon it in
order to get his purchase.

page_text: I HARRY THRESHER of 19 Dalston Lane in the County of Middlesex Engineer
late of Brixton Rise in the County of Surrey do hereby declaro the nature of
my Invention for IMPROVEMENTS IN THE STEERING APPARATUS OF VELOCIPEDES
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My invention is for improving the steering of Tricycles that have the two
driving or steering wheels side by side-the rider sitting between them on a saddle
on the backbone.
Instead of steering with the handle bars fixed on the front frame carried by the
-axle I place a socket on the backbone in front of the rider this socket has a short.
arm at the sido a corresponding arm is fixed to the head of the machine, these two
arms are connected by means of a link, or in place of these arms a chain or steel
band might be used to make the connection.
The handle bar is fixed on the socket so that when tho rider's weight is entirely
on the treadles, which are carried by the front frame and axle, the steering will be
effected from the backbone in the same way as if the rider was sitting upon it in
order to get his purchase.
This invention has for its object improvements in velocipedes having two steering
or driving wheels parallel with each other to increase the leverage for steering
such wheels and preventing the swerving of the machine when running on uneven
-ground.
Another advantage claimed by this invention is that having a separato fixing on
the backbone for the handle bars instead of their being direct on the head the jar
or vibration is considerably lessened.
And in order that my invention may be more clearly understood I will now
proceed to fully describe the same by reference to the accompanying Drawings.
Fig: 1 is a Machine with Steering completo.
Fig 2. is an enlarged view of my steering.
A is the head of Machine.
B Cone or plain pin on Backbone.
C Socket working on pin.
D Handle bar on Socket instead of head.
E Arm about one and a half inches long on side of head.
F Arm on Socket about one inch long.
G Link connecting the said two arms.
H Backbone and Neck of Machine.
'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 an improvement in the steering of Humber pattern tricycles or
Velocipedes Steered in a similar manner consisting in attaching the steering handles
to a fixing upon the backbone instead of upon the head and connecting the
handles with the head by means of a link chain or Steel band.
Dated this 8th December 1884.
