I, FRANK JOSEPH MAIER, of Spring Works, Sandiacre, near Nottingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in woven wire mattresses which in some
cases are further supported by spiral springs whose upper coil is threaded into the web
of the mattress.
Its object is to provide an improved arrangement of hinge like point or connection
between two of such mattresses by which they may be folded together; also to provide
an improved arrangement of threading the upper coil of the spiral springs into the
web of the mattress.
This the first part of my invention relates to the edges of each of the mattresses
which are to be folded together.
As is well known around the edges of the mattress two three or more coils are.
woven together, which forms a kind of framework from which and to. which the
interior cross strands or webs are carried.
When two of such mattresses are to be foldable, one edge of the one is connected to
one edge of the other by spirally twisting a coil or coils of wire along their length
which alternately takes hold of each edge, and thus forms a kind of hinge joint. The.
ends of these wires however are troublesome in their disposal, as however carefully
they are bent out of the way, they are apt to project and tear the bedding &c.
In my invention I bend into shape the one framework of coils, and then intertwine or
twist into and along one edge, the double or treble coil that is to form the framework
of the adjoining mattress. The two outer ends are now bent at right angles to the
connecting joint and continued around and their ends secured together in the usual
manner thus forining the second framework for the interlacing. Thus a strong hinge
joint is made directly between the two frame coils, with no wire ends about such joint.
Again. The lines of interlacing coils with the frame like edges are at 60° to each
other, so that the spaces are hexagonally disposed. Beneath these are the spiral
spring coils. Hitherto these spiral coils have been placed concentrically below one of
such spaces, so that its upper coil necessarily could only be threaded into six lines of
such interlacing coils. In my invention I place the said spiral springs concentric with
the point of intersection of lacing, and provide that the diameter of the upper coil of the
spiral spring is larger than that of the combined three immediate spaces. Hence
the spiral may be threaded through the nine surrounding lines of interlacing instead
of six as before. This is a great advantage, inasmuch as it distributes the wear over
more points, and more evenly supports the weight upon the interlacings.

page_text: Improvements in Woven Wire Mattresses.
I FRANK JOSEPH MAIER, of Spring Works, Sandiacre, near Nottingham,
Manufacturer, 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 improvements in woven wire mattresses which in some
cases are further supported by spiral springs whose upper coil is threaded into the web
of the mattress.
Its object is to provide an improved arrangement of hinge like joint or
connection between two of such mattresses by which they may be folded together;
also to provide an improved arrangement of threading the upper coil of the spiral
springs into the web of the mattress.
In order to more particularly describe this my invention, I have appended
hereunto an illustrative sheet of drawings, upon which are figures and numbers of
reference, similar numbers referring throughout the several views to the same
thing ör part.
Fig. 1, is a general plan view of my invention as applied to two mattresses which
are hinged together.
Fig. 2, is a detailed enlarged view showing the formation of the hinge joint, the
one end of such joint only being shown.
Fig. 3, is an enlarged side view of the spiral spring..
Fig. 4, is an enlarged plan view of the spiral spring, showing its threadings
into the interlacing coils.
The first part of my invention relates to the edges of each of the mattresses
which are to be folded together.,
As is well known around the edges of the mattress two, three, or more coils are
woven together, which forms a kind of framework from which, and to which, the
interior cross strands or webs are carried. When two of such mattresses are to be
foldable, one edge of the one is usually connected to one of the other by spirally
twisting a coil or coils of wire along their length which alternately takes hold of
each edge, and thus forms a kind of hinge joint. The ends of these wires however
are troublesome in their disposal, as however carefully they are bent out of the way,
they are apt to project and tear the bedding &c.
In this my invention I may make the framework of one of the 'mattresses
complete, say for instance that shown at 6. I then take a similar double or treble
coil 7, in the straight and directly twist or coil it into and along the one side of
the frame 6.
The two outer ends 8, 8, are now bent at right angles to the connecting joint and
continued around and their ends secured together in the usual manner thus forming.
the second framework 7, for the interlacing.. Thus a strong hinge joint is made.
directly between the two frame coils with; no wire ends about such joint.
Referring to the second part of this my invention:-The lines of interlacing
coils 9, 10 and 11 are at 60° to each other, so that the spaces are hexagonally disposed.
Beneath these are the spiral spring coils 12" Hitherto these spiral coils have been
placed 'concentrically below one of such spaces so that its upper coil necessarily could
only be threaded into six lines of such interlacing coils. "In my invention I place
the said spiral springs concentric with the point 13 of intersection of lacing, and
provide that the diameter of the upper coil of the spiral spring is larger than that
of the combined three immediate or adjoining spaces 23, 24 & 25. Hence the spiral
may be threaded through the nine surrounding lines of interlacing at 14, 15, 16, 17,
18, 19, 20, 21, and 22 instead of six as before. This is a great advantage inasmuch

page_text: as it distributes the wear over inore points, and more evenly supports the weight
upon the interlacings.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. In woven wire mattresses the method of connecting two of such mattresses
together by twisting the frame coil of the one directly into and along the frame coil
of the other, substantially as set forth and shown upon the drawings.
2. In woven wire mattresses having in combination therewith spring coils 12, the
disposing of the said spring coils 12, concentric with intersecting points 13 of
interlacing and threading of the said coil spring through the nine points of
interlacing, substantially as set forth and shown.
