and other purposes.
I, MARCEL COSSET, 14, Rue Demarquay, Paris, Builder, do hereby declare the
nature of this invention to be as follows:-
"
The detachable handle" which forms the subject of the present invention
is not only applicable to the velocipede industry for which it has been con-
structed but also to any other purpose such as tools, domestic utensils, hard-
ware, &c., &c.
This handle differs from others in construction by its simplicity, promptness
with which it can be attached or detached; it can be utilised whenever one has
to fit a handle on a tube as is the case with velocipede handles &c.
The handle is suitably hollowed to receive a core which is fixed thereto by
adhesion or in any other manner, the tube to which one wishes to adapt the
handle; the core or hollowing of the handle, should be adjusted to the outer
diameter of this tube.
The core which is the essential part of the handle is formed in two diameters,
the small diameter serves to fix the core to the handle, the large diameter which
fits rather loosely in the tube has a groove which presents at this part of the
core an eccentric section. In this groove runs a ball-which on the other hand
comes into contact with the side of the tube. Adaptation of the handle with
its ball to a tubular shaft is obtained by placing the ball at the deepest part of
the groove and fixing the core in the, said tube, then turning the handle to the
left to make the ball drop and turning strongly to the right to obtain a block
wedging of the ball between the tube and eccentric part of the core.
The handle can be readily detached by an inverse movement to that given in
attaching. It is evident that one could multiply the eccentric grooves and
number of balls over the length of the core.
In a modified arrangement provide a core similar to that above described
but the groove of which is helical forming an eccentric like the first; wedging
is operated in the same way but the distance to which the handle enters the
tube is not exactly determined as in the first type.
The handle and fixing core above described can be made in any shape and of
any material, wood and horn, wood and celluloid, wood and metal, &c.

and other purposes.
I, MARCEL COSSET, 14, Rue Demarquay, Paris, Builder, 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 "detachable handle" which forms the subject of the present invention
is not only applicable to the velocipede industry for which it has been con-
structed but also to any other purpose such as tools, domestic utensils, hard-
ware, &c., &c.
This handle differs from others in construction by its simplicity, promptness
with which it can be attached or detached, it can be utilised whenever one has
to fit a handle on a tube as is the case with velocipede handles &c.
Referring to the annexed drawings:-
-
Figure 1, sectional side elevation of my invention.
Figure 2, section through line AB.
Figure 3, sectional side elevation of modified arrangement.
Figure 4, sectional end view of same.
The handle a is suitably hollowed to receive a core b, which is fixed thereto
by adhesion or in any other manner, and the tube c to which one wishes to
adapt the handle, the core or hollowing of the handle a should be adjusted to
the outer diameter of this tube c.
The core which is the essential part of the handle is formed with two diameters,
the small diameter 6 serves to fix the core to the handle, the large diameter
which fits rather loosely in the tube has a groove e which presents at this part
of the core an eccentric section. In this groove e runs a ball f which on the
other hand comes into contact with the side of the tube. Adaptation of the
handle with its ball to a tubular shaft is obtained by placing the ball at the
deepest part of the groove and fixing the core in the said tube, then turning the
handle a to the left to make the ball drop' and turning strongly to the right to
obtain a block wedging of the ball between the tube and eccentric part of the
core.
The handle can be readily detached by an inverse movement to that given in
attaching. It is evident that one could multiply the eccentric grooves and
number of balls over the length of the core.
Figures 3 and 4 show a modified arrangement in which I provide a core similar
to that above described the helix el forming an eccentric like the first, wedging
is operated in the same way but the distance to which the handle enters the tube
is not exactly determined as in the first type.
The handle and fixing core above described can be made in any shape and of
any material, wood and horn, wood and celluloid, wood and metal, &c.
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:
A detachable handle applicable to every kind of industry, and characterized
by its mode of attachment or ball locking, this locking with one or more balls

page_text: being the combination of a cylindric wall and an eccentric wall with one or
several intermediary wedging balls, all as above set forth and represented in
accompanying drawings and specification.
