I, CHARLES WILLIAM RUDOLPH DUERRE, of 15 Kings Road, Chelsea in the
County of Middlesex, Watch and Clock maker, do hereby declare the nature of my
said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention applies chiefly, though not exclusively, to velocipedes having three
wheels only; and has for its object the carrying out of a simple and efficient
method of actuating the steering wheels.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation of a tricycle, the steering wheel being behind, and the
near" driving wheel, and other unnecessary parts for this purpose, being omitted.
Fig. 2 is a plan shewing the method of steering, as in Fig. 1; and Fig. 3 shews
another application of my invention to a front-steering tricycle a a are the driving
wheels, b is the steering wheel and c is the steering handle. In Figs. 1 and 2 the
steering bar is fitted at d, with a horizontal levere having a slotted end f; and
the fork of the steering wheel b is fitted with another horizontal lever g, having a
wheel or roller h which works in the slot f of the lever e
When the steering handle c is turned to the right (as shewn in Fig. 2) the
vehicle is caused to travel in the same direction; thus enabling the rider to steer
with certainty and precision, and rendering the steering more prompt steady and
effective than the rack and pinion movement.
In Fig. 3 I have shewn the application of my invention to a tricycle with the
steering wheel in front a a are the driving wheels; c (dotted lines) shews the
position of the steering handle and bar; e¹ is a lever attached to the steering bar,
and g¹ is a lever fitted to the fork of the steering wheel 61 The levers e¹ and gl
are fitted with antifriction rollers h¹ h which work in the slots f¹ƒ³ of the lever k.
This lever is provided in order that the tricycle may always travel in the
direction indicated by the lever e¹; but front-steering tricycles may, if preferred,
be fitted with two levers only, as shewn in Fig. 2, with such slight modifications
of parts as would be required to adapt it to that form of tricycle.

page_text: The means adopted for preventing undue friction arising at the ends of the
levers may be varied without departing from the principle of my invention; and
my invention may be applied to tandem velocipedes with three or four wheels;
and also to sociable velocipedes.
In the form of velocipedes in which two driving wheels and two steering wheels
are upon the ground, at the same time, the arrangement shewn in Fig. 3 is
preferably used for the front steering wheel, united with that shewn in Figs. 1
and 2 for the hind steering wheel, the two bars e and e¹ being made as one double-
ended lever actuated from the centre for that purpose, with similar anti-friction
appliances or their equivalents.
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. The manufacture and use of velocipedes fitted with levers e and g, whereby
the motion of the steering handle is communicated to the steering wheel, operating
substantially as hereinbefore described and shewn in Figs. 1 and 2 of the drawings.
2. The manufacture and use of velocipedes with three or four wheels, and of the
tandem or sociable classes, fitted with levers eg as aforesaid or with levers c¹ gl
and k or with both modifications of my invention, combined, substantially as
herein before described and shewn on the drawings.
3. The general arrangement combination and construction of the several and
respective parts, together forming my improvements in the method of steering
velocipedes and in apparatus therefor, substantially as herein before described and
shewn on the drawings.
