PROVISIONAI, SPECIFICATION
An Improved Device for Tensioning or Stretching Wire or
the like.
I, ISIDORE BARTHOU, of 10 occupation, of Pau, Basses Pyrénées, in the
Republic of Fiance do hereby declare the nature of this invention to be as
follows:
This improved device, by means of which a wire, cord, chain or the like may be
stretched and maintained at the desued tension, is constructed as follows,-In a
suitable holder preferably made of bent flat metal with incans for securing it, is
mounted a spindle having a transverse hole or passage for the end of the wire or
the like to be stretched. This spindle is made and fitted in its holder in an improved
nanne; the spindle increases in diameter towards its ends so as to form Hauges
and terminates in squared ends so that it may be turned by the key provided for
that purpose. The aforesaid flauges lie against the inner surfaces of the bow of
the holder in which the spindle 18 mounted and consequently the squared ends lie
in and project from the passage ways in the extremities of the bow of the holder.
These passage ways are made with two flat faces meeting at an angle m the
duection in which the tension of the wire or the like will be directed on the spindle,
so that the said tension draws the squared ends laterally against these faces, which
fitting closely to the two adjacent faces of the squared end prevent the spindle
from evolving under the tension of the wire. The passage ways are sufficiently
wide to the other side of each spindle ond to permit the spindle to be turned by its
key the pressure applied to which causes the faces of the squared ends of the spindle
to leave the faces of the passage way.
In place of employing a squared part of the spindle to lie in a passage way of
which one side is made as above described, the construction may be modified in any
way whereby the tension of the wire causes the spindle to be laterally pulled in a
suitably shaped passage way so that a stop on the spindle comes in contact with a stop
which prevents the revolution of the spindle in the direction in which otherwise it
would be revolved by sand tension. Thus the end of the passage way may form or
have a detent or cog and the spindle may be provided with ratchet teeth to engage
therewith, the passage way being suitably extended in the other direction to enable
the teeth to pass over the cog when the spindle is revolved to wind up the wire.

An Improved Device for Tensioning or Stretching Wire or
the like.
I, ISIDORE BARTHOU, of no occupation, of Pau, Basses Pyrénées, in the
Republic of France, 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 improved device, by means of which a wire, cord, chain or the like may be

page_text: stretched and maintained at the desired tension, is constructed as follows -In a
suitable holder C preferably made of bent flat metal with means for securing it, 1s
mounted a spindle A having a transicise hole or passage for the end of the wire
or the like to be stretched. This spindle is made and fitted in its holder in nu
improved manner. The spindle increases in diameter towards its ends so us to form
flanges and terminates in squated ends c so that it may be turned by the key
provided for that pu pose. The aforesaid flanges lie against the inner surfaces of
the bow of the holder in which the spindle is mounted and consequently the squared
ends lie in and project from the passage ways e in the extremities of the bow of the
holder. In Fig. 1 these passage ways are made with two flat faces meeting at an
angle in the direction in which the tension of the wire or the like will be directed
on the spindle, so that the said tension dians the squared ends laterally against
these faces, which fitting closely to the two adjacent faces of the squared end
prevent the spindle fiom revolving under the tension of the wire.
The passage
ways are sufficiently wide to the other side of each spindle end to permit the
spindle to be turned by its key the pressure applied to which causes the faces of
the squared cuds of the spindle to leave the faces of the passage way.
In place of employing a squared part of the spindle to lie in a passage way of
which one side is made as above described, the construction may be modified in any
way whereby the tension of the wne causes the spindle to be Interally pulled in a
suitably shaped passage way so that a stop on the spindle comes in contact with a
stop which prevents the revolution of the spindle in the direction in which otherwise
it would be revolved by said tension. Thus as in Fig. 2 the end of the passage
way may form or have a detent or cog f and the spindle may be provided with
intchet teeth to engage therewith, the passage way being suitably oxtended in the
other direction to enable the teeth to pass over the cog when the spindle 18 revolved
to wind up the wie
Having now particularly descubed and ascertained the nature of the said
invention and in what manuoi the same is to be performed, I declare that what I
clan is:-
The improved device for stretching or tensioning wire constructed as above
