COMPLETE SPECIFICATION.
Improvements in Velocipedes.
I HERBERT JOHN HADDAN of the firm of Herbert. & Co., Patent Agents of
18 Buckingham Street Strand W.C. London Civil Engineer do hereby declare the
nature of this invention a communication to me from abroad by Maxime Mavet-
Metcalf, Engineer of Orleans 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 velocipedes and principally to bicycles and tricycles
in which the pedal-shaft is distinct from the main driving wheel shaft. The
improvements have for their object to do away with chain gear for connecting the
pedal shaft with the driving wheel shaft and consist in the construction of mitred
gearing wheels fixed respectively to the pedal crank-shaft and a rod connected with
mitred gearing fixed respectively on the said rod and the axle of the driving wheel,
suid rod being preferably concealed with the fork which is tubular combined with
above. A brake is arranged that may be operated by the foot or hand consisting of a
wheel keyed on the pedal axle controlled by a strap furnished with a lever for
tightening it similar to an ordinary hand-brake, but placed on the pedal crank shaft in
place of on the wheel-shaft.
In the accompanying drawings: Fig. 1 is a side elevation of a bicycle fitted with
the improvements; fig. 2 is a plan view of part thereof with brake omitted'; fig. 3
illustrates the application of the invention to a tricycle. B is the rod with mitre
gearing B and B; D the pedal crank shaft, A the band brake, A¹ the lever thereof,
and C the rod thereof.
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:
In a velocinede the gearing of nedal crank shaft with the drink

page_text: means of mitre gear on said shafts engaging with mitre gear on a rod journalled
within the fork or framework substantially as set forth.
2) The arrangement of a band brake on the pedal crank shaft substantially as set
forth.
