Improvements in Velocipedes.
I WILHELM MECHLER of Naudamm in the Province of Brandenbourg, Kingdom
of Prussia, German Empire, Manufacturer do hereby declare the nature of this
invention to be as follows:-
This invention refers to bicycles of the class in which a cog wheel mounted
upon the driving axle is driven by a cog wheel fixed upon the crank axle by the
aid of a spur wheel meshing with the said two former wheels. My improvements
in bicycles of that class relate to the means for forming and holding the bearing
or bearings for this intermediate spur wheel. I have shown my improved
construction in the accompanying drawing in which Fig. 1 is a side elevation of
my improved bicycle, while Fig. 2 is partly a longitudinal section on line za of
Fig. 1.
a is the intermediate spur wheel and a the axle of the same. Said axle is
supported at its outer end by the front end of an arm e the rear end of which
is held by the driving axle i of the bicycle. The cog wheel o of this axle is
arranged between said arm e and the corresponding leg of the fork e. The other
or inner end of the axle a aforesaid is held at the junction of the two rods e² et
the former of which is secured at its upper end to the frame of the bicycle. The
front end of the rod e is also secured to this frame but to the lower part of the
same i.e. at the-junction of the tubes ete of the said frame. The parts e³ et e
carry the axle u¹ of the cog wheel u. The cranks u are obviously secured to the
said axle ¹.

Improvements in Velocipedes.
I WILHELM MECHLER, of Neudamm in the Province of Brandenbourg, Kingdom
of Prussia, German Empire, Manufacturer 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:-
This invention refers to bicycles of the kind in which cog wheels located upon
the driving axle is driven from a cog-wheel located upon the crank axle by the
mediation of a cog-wheel meshing with said two former ones.
My improvements in bicycles of said kinds relate to the means of forming or
holding the bearing or bearings for said third or intermediate cog wheel.

page_text: I have shown my improved construction in the drawings left with Provisional
Specification in which
a is the intermediate cog wheel and a¹ the axle of the same. Said axle is
supported at its outer end by the one end of an arm e¹ the opposite end of which
is held by the driving axle i of the bicycle. The cog-wheel o of this axle is
arranged between said arm e¹ and the respective prong of the fork e. The other
or inner end of the axle a¹ afore mentioned is held by the place of conjunction
of two rods ee³, the former of which is secured at its upper end to the main
frame of the bicycle. The front end of the rod e³ is also secured to said main
frame, but to the lower part of the same, i.e. to the place of conjunction of the
tubes ee of the said frame. The parts e e e hold and form a bearing for the
axle u¹ of the cog-wheel u. The cranks u are, of course, secured to said axle u¹.
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. In a bicycle having an intermediate cog wheel for transmitting the rotations
of the crank-axle-wheel to the driving-axle-wheel, the combination of the rod e
attached to the driving-axle and the rod e³ attached to the crank-axle, of a
bearing for said intermediate cog-wheel, said bearing being formed or supported
by the adjacent parts of said rods, substantially as described.
2. In a bicycle having an intermediate cog-wheel for transmitting the rotations
of the crank-axle wheel to the driving-axle-wheel, the combination of the rod el
attached to the driving-axle and the rod e³ attached to the crank-axle, of a
bearing formed or supported by the adjacent parts of said rods and of a rod or
tube holding one or the other or both, of said rods e e³, and thereby the said
bearing proper in a normal height or position, substantially as described.
