PROVISIONAL SPECIFICATION.
Improvements in Tubes and Bars for the Manufacture of
Velocipedes.
I, ABEL ALEXANDRE MAZET, of 224 Rue des Pyrennies, Paris in the
Republic of France, Gentleman, do hereby declare the nature of this invention to
be as follows:-
:-
The object of this invention is an improved tube or bar applicable for the
construction of all sorts of velocipedes.
It has been the practice in the construction of all sorts of velocipedes and the
ike to replace the massive iron or steel bars by tubes of cylindrical, conical,
truncated conical, or oval shape which, apart from the advantage of lessened weight,
impart to the velocipedes at the same time strength, elasticity and elegant
appearance.
However since this great revolution in this industry which has given to
velocipedes greater rapidity, no.one has endeavoured to replace the cylindrical or
conical tubes by a tube of a more suitable form.
For this purpose I have devised a triangular tube for the construction of
bicycles, tricycles etc. and other velocipedes or vehicles which offers in fact a
smaller sectional surface in comparison to the surface of the cylindrical tube and
at the same time a much greater resistance and solidity, moreover the triangular
form is more pleasing in aspect and slender.
n
Solid bars, such as the saddle bar, arc, according to this invention made in the
same cross sectional form, which is that of a triangle with rounded corners.

Improvements in Tubes and Bars for the Manufacture of
Velocipedes.
I, ABEL ALEXANDRE MAZET, of 224 Rue des Pyrennies, Paris in the
Republic of France, Gentleman, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of this invention is an improved tube or bar applicable for the
construction of all sorts of velocipedes.
It has been the practice in the construction of all sorts of velocipedes and the
like to replace the massive iron or steel bars by tubes of cylindrical, conical,
truncated conical or oval shape, which, apart from the advantage of lessened
weight, impart to the velocipedes at the same time strength, elasticity and elegant
appearance.
However, since this great revolution in this industry, which has given to
velocipedes greater rapidity, no one has endeavoured to replace the cylindrical or
conical tubes by a tube of a more suitable form.

page_text: For this purpose I have devised a triangular tube for the construction of
bicycles, tricycles etc. and other velocipedes or vehicles which offers in fact a
smaller sectional surface in comparison to the surface of the cylindrical tube and
at the same time a much greater resistance and solidity; moreover the triangular
form is more pleasing and slender in aspect..
Solid bars, such as the saddle bar, are according to this invention made in the
same cross sectional form, which is that of a triangle with rounded corners.
For use in the construction of cycles, bicycles, tricycles quadricycles and vehicles
in general, of every description, this triangularly shaped tube may be made of brass,
copper, cast-iron, iron, steel, aluminium or any other appropriate metal, moulded,
cast, soldered, cold or hot drawn or rolled or made by any other process of
manufacture.
In the annexed drawing Figs. 1 and 2 show two kinds of triangular sectioned
tubes having their angles rounded off to a less and greater degree respectively.
For certain purposes these triangular sections are made solid and thus become
bars of likewise triangular section, to be used for instance for supporting velocipede
saddles etc.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. Tubes and solid bars of triangular section substantially as described and
illustrated for the manufacture of velocipedes.
2. The construction of velocipedes with their frames of tubes and bars of
triangular cross section substantially as described.
