PROVISIONAL SPECIFICATION.
Improved Work Holder for Sewing Tables and the like.
I, VICTOR KOBLER-STAUDER, of Arbon in the Republic of Switzerland,
Textile Expert, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a device for clamping or holding firm material
whilst being sewn, and consists of an eccentric piece arranged on a supporting
surface, which piece holds the material lying on this supporting surface firm when
the material is drawn, whilst being worked, towards the one side of the eccentric,
whilst, owing to the eccentricity of the piece, the material is easily released when
it is drawn out in the opposite direction.
This automatic material holder is shown on the accompanying drawing in a front
and side view, Figures 1 and 2 respectively.
Two somewhat sidewardly curved arms b and c are arranged on a clamp a, which
may be fastened by means of a screw to a table top; one of these arms b carries.
the plate d, which serves for supporting the material or work, whilst the other chas
a horizontal arm e. The eccentric g is movably attached to this arm e by means of
a screw fand is pressed against the plate d by the action of a weight, such for
instance as the spherical weight h, or even by the action of a spring, and may be.
suitably roughened or jagged on its eccentrically curved part.
If the material S be inserted between the plate d and the eccentric g, and be
drawn for instance during sewing in the direction of the arrow, Figure 2, it is
evident that the pressure of the eccentric against the table will increase in the same
degree as the pulling force, and will hold the material securely fast whilst being
worked upon.
It suffices in order to immediately release the material to give it a slight push in
the opposite direction or to lift the ball h with the finger.
The sideways curved arms b and c form between them a recess for receiving
the edge of the material.
A pin i may also be arranged on the arm c for the spool of thread.

Improved Work Holder for Sewing Tables and the like.
I, VICTOR KOBLER-STAUDER of Arbon in the Republic of Switzerland,
Textile Expert, 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 has for its object a device for clamping or holding firm material
whilst being sewn, and consists of an eccentric piece arranged on a supporting
surface, which piece holds the material lying on this supporting surface firm when
the material is drawn, whilst being worked, towards the one side of the eccentric,.
whilst, owing to the eccentricity of the piece, the material is easily released when
it is drawn out in the opposite direction.
This automatic material holder is shown on the drawing accompanying th
Provisional Specification in a front and side view, Figures 1 and 2, respectively.
Two somewhat sidewardly curved arms b and c are arranged on a clamp a, which.

page_text: may be fastened by means of a screw to a table top; one of these arms 6 carrie
the plate d, which serves for supporting the material or work, whilst the other c
has a horizontal arm e. The eccentric g is movably attached to this arme by
means of a screw f and is pressed against the plate d by the action of a weight,
such, for instance, as the spherical weight h, or even by the action of a spring, and
may be suitably roughened or jagged on its eccentrically curved part.
If the material S be inserted between the plate d and the eccentric g, and be
drawn, for instance, during sewing in the direction of the arrow, Figure 2, it is
evident that the pressure of the eccentric against the table will increase in the
same degree as the pulling force, and will hold the material securely fast whilst
being worked upon.
It suffices, in order to immediately release the material, to give it a slight push
in the opposite direction or to lift the ball h with the finger.
The sideways curved arms b and c form between them a recess for receiving the
edge of the material.
A pin may also be arranged on the arm c for the spool of thread.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
claim is :-
1. An automatic work holder, characterised by having an eccentric piece (g)
situated above a supporting plate (d) and resting with its increasing radius thereon,
for the object of holding a piece of material between such piece and plate, and that
in such manner that the material, on a movement in the one direction (that is, in a
direction of the pull of the work) will be held fast, and, on a movement in the
opposite direction, will be released."
2. In an automatic work holder, two arms (c and b) forming between them a
recess for receiving the material falling down between them.
