PROVISIONAL SPECIFICATION.
Improvements in or relating to Wire or Metallic Mattresses.
We HEINRICH WESTPHAL and HERMANN REINHOLD both of the firm of
Westphal & Reinhold, Mattress Manufacturers, of Wassergasse 30, Berlin S.O. in
the Empire of Germany do hereby declare the nature of this invention to be as
follows:-
This invention relates to that class of mattresses in which a network is supported
and stretched upon a suitable frame by means of springs and hooks or other con-
nection, the said network being composed of a number of rings of wire or metal
connected by other rings or hooks in such a way as to form a connected fabric or
sheet resembling a net and of the size and shape desired.
In such nets, as heretofore made, the movement of the rings or parts one upon
the other at each movement of the position of weight upon the mattress causes a
grating or scratching or other unpleasant or disturbing noise; and it is the object
of this invention to so construct such nets that these noises may be avoided in a
great measure and substantially overcome.
The noises being due to the sliding of one surface of metal over another, the
object of the present improvement is to so construct the nets that, in giving to the
shifting of the weight thereon, this sliding of one part on another may be avoided
or reduced to a minimum.
In place of constructing the net so that at least three hooks were connected to
each ring, the nets according to the present invention are made so that each ring
holds or receives two hooks only. By this means the rings allow the hooks to
move relatively to each other with only rolling contact and no sliding contact on
the rings. The hooks however, or a certain number of them sufficient for con-
necting the net, are made of or from parts constructed of sheet metal or bent wire
or otherwise in such a manner that at least, three hooks are rigidly connected
together in each body so as to allow of the joining up of the rings to form a
net without departing from the rule of having but two points of connection for
each ring.

Improvements in or relating to Wire or Metallic Mattresses.
We, HEINRICH WESTPHAL and HERMANN REINHOLD, both of the firm of
Westphal & Reinhold, Mattress Manufacturers, of Wassergasse 30, Berlin, S.O.
in the Empire of Germany, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to that class of mattresses in which a network is supported
and stretched upon a suitable frame by means of springs and hooks or other con-
nection the said network being composed of a number of rings of wire or metal
connected by other rings or hooks in such a way as to form a connected fabric or
sheet resembling a net and of the size and shape desired.
In such nets, as heretofore made, the movement of the rings or parts one upon
the other at each movement of the position of weight upon the mattress causes a
grating or scratching or other unpleasant or disturbing noise; and it is the object

page_text: of this invention to so construct such nets that these noises may be avoided in a
great measure and substantially overcome.
The noises being due to the sliding of one surface of metal over another, the
object of the present improvement is to so construct the nets that, in giving to the
shifting of the weight thereon, this sliding of one part on another may be avoided
or reduced to a minimum.
In place of constructing the net so that at least three hooks were connected to
each ring, the nets according to the present invention are made so that each ring
holds or receives two hooks only. By this means the rings allow the hooks to
move relatively to each other with only rolling contact and no sliding contact on
the rings. The hooks however, or a certain number of them sufficient for con-
necting the net, are made of or from parts constructed of sheet metal or bent wire
or otherwise in such a manner that at least three hooks are rigidly connected
together in each body so as to allow of the joining up of the rings to form a
net without departing from the rule of having but two points of connection for
each ring.
In the accompanying drawings
Fig. 1 shows the former method of constructing such a net. It will be seen that
each ring carries three books.
In Fig. 2 is a diagramatic view of another form in which each ring carries four
hooks, supposing that the ring a (Fig. 1) moves to a' the link b in following such
movement tends to slide on the ring e, since the latter held by two other rings
cannot adapt its position so that the direction of pressure of the link is radial to
the centre of the ring without the slipping of the link b.
Fig. 3 shows the improved net in which a three fold hook connects the rings.
Fig. 4 shows a four fold hook.
Fig. 5 illustrates the change of the position of the rings in the improved net.
Fig. 6 illustrates another form of three fold connecting piece and the method of
attaching it.
Fig. 7 is another form of four fold connecting piece as shown in perspective.
Figs. 8 and 9 show parts of finished mattresses made with the improved nets.
Fig. 10 is a diagramatic view of a modified construction of net.
Referring to Figs. 3 and 5 it will be understood that when there are only two
hooks (9) to each ring the direction of pressure (c) may be altered in any
direction, for instance to c without causing either the one or other hook to slide on
the ring h. r is the mattress frame. s the springs.
Fig. 10 shows that the improved connectors may be used together with the
former double hook so long as no ring has more than two points of attachment.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:-
In a wire mattress the combination with the rings h or equivalent links of the
connecting pieces herein-described having not less than three hooks or equivalent
means of attachment to the rings h, whereby no ring may be connected at more
than two points of attachment for the purpose set forth.
