page_text: We, LOUIS BERGER and DAVID GLARDON-JAQUET, both of 6, Place St. Francois,
Lausanne, in the Republic of Switzerland, do hereby declare the nature of this
invention to be as follows:-
The invention consists of a turner's hand-chisel formed of a piece of steel of
rectangular shaped section the end of which is suitably bevelled to form the
cutting point of the chisel.
As a chisel of such a section would not be easily held firmly upon the support
of the lathe we provide upon the same a sliding bearing-piece also of rectangular
L shaped section forming with the section of the chisel a tool of substantially
square section on that portion of the same where it is to be applied upon the
tool rest of the lathe.
In carrying our invention into practice the chisel is formed of a piece of steel
of rectangular L-shaped section having a bevel, the edges of which form the
cutting point, and a reduced portion or tang intended to be secured in a wooden
handle. With this chisel there is symmetrically combined a sliding bearing-
piece also of rectangular L-shaped section, the edges of which are adapted to
embrace the edges of the chisel. The chisel and the bearing thus combined form
with one another a tool of square shape for that portion of the same which is to
be applied upon the tool rest of the lathe.

We, Louis BERGER and DAVID GLARDON-JAQUET, both of 6, Place St. Francois,
Lausanne, in the Republic of Switzerland, 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 relates to a turner's hand-chişel formed of a piece of steel of
rectangular shaped section the end of which is suitably bevelled to form the
cutting point of the chisel.
As a chisel of such a section would not be easily held firmly upon the support
of the lathe we provide upon the same a sliding bearing-piece also of rectangular

page_text: ☐ shaped section forming with the section of the chisel a tool of substantially
square section on that portion of the same where it is to be applied upon the
tool rest of the lathe.
In the accompanying drawing Figure 1 shows a front view of the improved
chisel.

Figure 2 shows a section on line x-y of Figure 1.
In carrying our invention into practice the chisel is formed of a piece of steel
of rectangular L-shaped section having a bevel A the edges a¹ and a² of which
form the cutting point a, and a reduced portion or tang A intended to be secured
in a wooden handle. With this chisel A there is symmetrically combined a
sliding bearing-piece B also of rectangular L-shaped section, the edges of which
are adapted to embrace the edges of the chisel Â as shown in Figure 2. The
chisel A and the bearing B thus combined form with one another a tool of square
shape for that portion of the same which is to be applied upon the rest of the
lathe.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
An improved turner's hand-chisel A of rectangular L-shaped section, in com-
bination with a sliding bearing B also of rectangular L-shaped section in view of
giving to that portion of the chisel of L-shaped section which is intended to be
applied upon the rest of the lathe a substantially square section, substantially
as shown and described.
