COMPLETE SPECIFICATION.
Improvements in Wire Spring Mattresses, Seats, and other
Cushions.
I FRANZ 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 the construction and arrangement of
wire spring mattresses, seats or cushious, and consists in the improved method or
arrangement of interlacing the longitudinal and diagonal spiral coils with each
other, and also their attachment to the vertical spiral.
In order to more clearly explain 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 or part,
and in which :-
Fig. 1, is a plan view showing a portion of this my invention.
Fig. 2, is a side view of a portion of my invention.
Fig. 3, is an enlarged detail view showing more clearly the method and
arrangement of interlacing the wire spirals with each other, and with the vertical
spirals.
A series of longitudinal single coil wires 4, 4, &c. consisting of two or more
said coils are arranged at a certain equal distance apart. Similarly are arranged
other series of diagonal coils 5, 5, &c., and at a similar equal distance apart. It
will be seen from the drawing (see Fig. 3) that these coils are separated and not
attached to those running in a similar direction, but only interlaced with those
crossing each other. This arrangement very much facilitates the putting together
of the spirals and affords a very simple yet elastic fabric.
It will be further seen that by this arrangement those portions 6, 7, 8, 9, 10
& 11 which form the hexagonal sides of the openings are of single and separated
spirals. Into these portions of spirals the outer coil 12, of the vertical spiral 13,
may now be threaded, the said coil passing through each of the spiral coils
presented, so that the support of the vertical spiral is distributed around the entire
circle at many points, see Fig. 3. This affords a firm yet elastic attachment of the
vertical spirals to the horizontal ones, and utilizes the advantages of both in a
siniple manner. The outer edge of the fabric is bordered or strengthened in the
usual manner by multiple coils 14, so as to afford a finish thereto and prevent
derangement.
Although I have only shown this my invention as having the vertical spirals in
combination with the horizontal ones, yet my improved spirally laced fabric
may in some cases be used without such vertical spirals, and with or without
a wire ring similar to the outer coil being threaded therein in the manner
shown.
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 wire spring mattresses, seats and other cushions, the combination with
vertical spiral springs 13, of the intermittent series of longitudinal and diagonal
independent horizontal spiral coils interlaced in the manner shown and described.
2. In wire spring mattresses, seats and other cushions, the combination of

similar series of diagonal spiral coils interlaced in the manner shown and
described.
