PROVISIONAL SPECIFICATION.
Improvements in Tricycles and other Velocipedes..
I REGINALD HADDAN of the firm of Herbert & Co. of 18 Buckingham Street,
Strand, W.C. in the County of Middlesex, Civil Engineer do hereby declare the nature
of this invention, a communication to me from abroad by Maxime Mavet-Metcalf,
Mechanical Engineer of Orleans in the Republic of France to be as follows:-
This invention relates to tricycles and other velocipedes.
In the improved tricycle the driving wheel is arranged towards the front and is
made smaller than is usual for direct driving. In place of a chain, the gear con-
necting the treddle crank shaft and the driving wheel consists only of a toothed pinion
or pinions on the hub of the driving wheel and an interiorly toothed wheel or wheels
on the treddle shaft gearing with said pinion or pinions.
The handle bar by which the steering is effected is made with the two branches
curved after the fashion of "Arab" springs so that while sufficiently rigid
horizontally for steering they are sufficiently elastic to obviate or lessen the
vibration.
This latter improvement is applicable to any velocipede having such handle bar.

Improvements in Tricycles and other Velocipedes.
I, REGINALD HADDAN, of the firm of Herbert & Co., Patent Agents, of 18, Bucking-
ham Street, Strand, W.C. London, in the County of Middlesex, Civil Engineer, do
hereby declare the nature of this invention, a communication to me from abroad by
Maxime Mavet-Metcalf, Mechanical Engineer, of Orléans, in the Republic of France,
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention relates to tricycles and other velocipedes.
In the improved tricycle the driving-wheel is arranged towards the front and is
made smaller than is usual for direct driving. In place of a chain, the gear con-
necting the treddle crankshaft and the driving wheel consists only of a toothed pinion
or pinions on the hub of the driving wheel and an interiorly toothed wheel or wheels
on the treddle shaft gearing with said pinion or pinions.
The handle bar by which the steering is effected is made with the two branches
curved after the fashion of "Arab springs so that while sufficiently rigid
horizontally for steering they are sufficiently elastic to obviate or lessen the
vibration.
This latter improvement is applicable to any velocipede having such handle bar.
The accompanying drawings illustrate the improved tricycle, Fig. 1 being a side
elevation and Fig. 2 a front elevation thereof. A is the driving-wheel, the axle of
which is journalled in the fork B and carries the pinions CC. The pedal cranks D D
are respectively formed with or fixed to the interiorly toothed wheels E E journalled
on gudgeons on the extensions F F of the fork B and gearing with said pinions C C.
The handle bar G is curved into a circular coil H in each branch as shown in Fig. 2,
said coil being in a vertical or substantially vertical plane.
The construction of the tricycle in other respects will be understood from the
drawings.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is. to .he performed, I declare that what I
claim is :-
1. A tricycle having two parallel trailing wheels and one small leading, wheel, said
leading wheel being the steering and driving wheel, with pinions on the axis
thereof and interiorly toothed wheels E E on or with the pedal cranks, gearing with
said pinions.
2.In a velocipede, a, handle bar the branches of which are curved each.in a coil; or
coils as illustrated and described.
