Improvements in Tools for Stretching Webbing for Mattresses,
Cushions, and the like.
We, THEODOR PERLS of 1/4 Schiesshaus Strasse, Würzburg, in the Kingdom of
Bavaria, German Empire, Manufacturer, and MAX WEEGMANN of 9 Domp-
faffengasse, Würzburg, in the Kingdom of Bavaria, Empire of Germany,
Upholsterer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a tool for stretching webbing which is fastened to
mattresses and cushions. This instrument may be applied to the webbing at any
place and avoids injury of the same. The webbing is first nailed to one side of
the frame of the mattress then drawn to the opposite side and there introduced
sideways into the tool and clamped by the same; hereafter the tool is placed upon
the edge of the frame and the webbing is spanned as much as desired by turning
the tool down toward the outside.
Heretofore the tools for the same object consisted of broad board-like pieces of
wood provided at the front with a series of iron teeth, and were secured to the
webbing simply by driving said teeth into the ends of the same. This manipula-
tion, though being a very easy one, was greatly defective, as will be apparent on
considering that the teeth tore holes or rents in the webbing, thus damaging the
places where the tool was affixed.
Other tools, similar to our improved one by the manner in which the webbing
is held, presented however the defect that they had to be drawn over the end of
the webbing, which not only was very inconvenient, but altogether impossible in
many cases.
All the difficulties and deficiences experienced in the application of these tools
have been overcome by our invention. The lower end of the piece of wood
mentioned above is provided with a clamping device, which can be very easily
applied to the webbing; this device also allows of the lateral insertion of the latter,
so that it is not necessary to secure the tool to the end of the same; thereby we
are enabled to employ webbing made of bands without end, which hitherto was
impossible.

Improvements in Tools for Stretching Webbing for Mattresses,
Oushions, and the like.
We, THEODOR PERLS of 20, Melanchton Strasse, Berlin, in the Kingdom of
Prussia, German Empire, Manufacturer, and MAX WEEGMANN of 9 Domp-
faffengasse, Würzburg, in the Kingdom of Bavaria, Empire of Germany,
Upholsterer, 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:-
Our invention relates to a tool for stretching webbing which is fastened to
mattresses and cushions. This instrument may be applied to the webbing at any
place and avoids injury of the same. The webbing is first nailed to one side of the
frame of the mattress, then drawn to the opposite side and there introduced

page_text: sideways into the tool and clamped by the same; hereafter the tool is placed upon
the edge of the frame and the webbing is spanned as much as desired by turning
the tool down toward the outside.
Heretofore the tools for the same object consisted of broad board-like pieces of
wood provided at the front with a series of iron teeth, and were secured to the
webbing simply by driving said teeth into the ends of the same. This manipula-
tion, though being a very easy one, was greatly defective, as will be apparent on
considering that the teeth tore holes or rents in the webbing, thus damaging the
places where the tool was affixed.
Other tools, similar to our improved one by the manner in which the webbing is
held, presented however the defect that they had to be drawn over the end of the
webbing, which not only was very inconvenient, but altogether impossible in many
cases.
.
All the difficulties and deficiences experienced in the application of these tools
have been overcome by our invention. The lower end of the piece of wood
mentioned above is provided with a clamping device, which can be very easily
applied to the webbing; this device also allows of the lateral insertion of the
latter, so that it is not necessary to secure the tool to the end. of the same.
thereby we are enabled to employ webbing made of endless stripes, which hitherto
was impossible.
Our invention will be more readily understood by reference to the accompanying..
drawings, in which :
Fig. 1 is a front elevation of our improved tool, showing the same in the open
position.
Fig. 2 a similar view showing the same in closed position.
Fig. 3 a side elevation corresponding to Fig. 1, and
Fig. 4 illustrates the application of our improved tool for stretching the
webbing of a mattress.
Similar letters denote similar parts throughout the several views.
Our improved tool consists firstly of a wooden board a provided on one of its
straight edges with a sheet-iron cover b having two lateral offsets c d extending
laterally thereof, and secured to the board a by means of nails or in any other
suitable manner. The offset c is provided with a hole, and the offset d with a
notch k. This hole and this notch receive the axle of a plate e constituted by.
two parts forming an angle with one another. The end of the axle g opposite the
notch is provided with a head f. The shorter part of the plate c is provided
with teeth i at its edge facing the metallic cover b. It will be, obvious that the
end of axle g may be slid out of the notch k and raised into the position shown
by the dotted lines in Fig. I.
The operation of our improved tool is as follows: The end of axle g is taken
out of the notch k and the plate e raised, as will be seen by reference to the dotted
lines in Fig. 1. The tool is then slid laterally over the webbing, and the end of
axle g again brought into the notch k. The plate e is then in the position
illustrated by full lines in Fig. 1. Hereafter the plate e is turned by means of its
longer part so as to clamp the webbing between the teeth and the sheet-iron
cover b, and the tool may then be employed in the usual manner by holding it
against the frame of the mattress and turning it downwards so as to stretch the
webbing, as will be seen in Fig. 4.
It will be obvious that any tension exerted in the direction of the arrow, Fig. 2,
will only increase the griping of the teeth i, as in consequence of the inclined form
of the notch k the axle g and the said teeth will be pressed more firmly towards
and into the webbing.
Having now fully 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
The hereinbefore described improved tool for stratehine mehhing of mattr

page_text: cushions and the like, consisting in the combination, with a board a and an iron
cover 6 secured to the same, said cover being formed with two lateral offsets o d
provided the one with a hole and the other with an oblique notch k, of the axle g
having a head fand adapted to be journaled in the offsets cd, and the plate e
pivotted by means of the axle g and provided with a row of teeth, i, on one of its
edges, substantially as and for the purpose described.
