Chairs, and other Articles of Furniture, Panels, Wire Belting,
and other Articles.
I, ALFRED EDMUND WALE of the Firm of T. E. Wale and Sons of
Atlas Works, Oozells Street Birmingham in the County of Warwick Manufacturers,
do hereby declare the nature of this invention to be as follows:-
The said invention has reference to wire fabric consisting of a series of interlocked
helical coils of wire and has for its object to so interlock the said coils together in the
manuer hereinafter described, that the fabric produced will not collapse under
moderate lateral pressure.
Wire fabric made according to the said invention is also superior to, in the
respect that it has a finer appearance than, fabrics made up of the same or
approximately the same number of helical coils interlocked in the ordinary way.
In making a fabric according to the said invention I take helical coils of wire
the diameters of the helices bearing to their pitch the ratio or approximately the
ratio of five to thirteen. I first form a compound helical coil consisting of four of
the said helices which I will respectively call the first, second third and fourth
helices. I then take a fifth helix and engage or interlock it by a screwing
motion with the convolutions of the first and third helices. I then add by

seventh helix with the fifth and sixth helices and an eighth helix with the
fifth, sixth and seventh helices and so on until the desired width of fabric is
obtained, each alternate and subsequently added helix engaging respectively with
the last two and the last three helices of the partially made fabric. In this way, a
fabric is produced the helical coils of which are not only interlocked but mutually
support each other.

I ALFRED EDMUND WALE, of the Firm of T. E. Wale and Sons, of Atlas
Works Oozells Street, Birmingham in the County of Warwick, Manufacturers do
hereby declare the nature of the said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement :-
The said invention has reference to wire fabric consisting of a series of interlocked

page_text: helical coils of wire and has for its object to interlock the said coils together in the
manner hereinafter described, whereby the fabric produced will not collapse under
moderate lateral pressure.
Wire fabric made according to the said invention is also superior to, in the respect
that it has a finer appearance than, fabrics made up of the same or approximately
the same number of helical coils interlocked in the ordinary way.
In making a wire fabric according to the said invention, I take helical coils of
wire the diameters of the helices bearing to their pitch the ratio or approximately
the ratio of five to thirteen. I first form a compound helical coil consisting of four
of the said helices which I will respectively call the first, second, third and fourth
helix. I then take a fifth helix and engage or interlock it by a screwing motion
with the convolutions of the first and third helices. I then add by interlocking with
the first, third and fifth helices a sixth helix. I then interlock a seventh helix with
the fifth and sixth helices and an eighth helix with the fifth sixth and seventh helices
and so on until the desired width of fabric is obtained, each alternate and inter-
mediate helix subsequently added engaging respectively with the last two and the
last three helices of the partially made fabric, that is, in adding two more helices
to the fabric, the first added helix engages with the last two helices of the
fabric and the next helix engages with the last three and so on.
In this way
a fabric is produced the helical coils of which are not only interlocked but mutually
support each other.
Figure 1 of the accompanying drawing represents a portion of a compound helix
made up of four intercoiled wire helices and Figures 2, 3, 4 and 5 represent the
several stages or steps in the manufacture of the said improved fabric from the
compound helix Figure 1 and the additional helices intercoiled therewith in
the manner hereinafter described.
In Figure 1 I have marked the four helices 1, 2, 3 and 4 respectively and the
same numbers indicate the same helices in the several figures of the drawing.
I take the compound helix Figure 1 and intercoil a fifth helix marked 5 in
Figure 2 with the helices I and 3 of the compound helix. By so doing the helix 2
is forced back or out of line with the compound helix and is rigidly held or supported
by the helices 1, 3 and 5, the helices 2 and 5 being symmetrically disposed on
either side of the compound helix as seen in Figure 2. I now take a sixth helix
marked 6 in Figure 3 and intercoil it with the helices 1, 3, and 5. By the addition
of the helix 6 the helix 4 is forced into line with the helix 2, the helix 6 being in line
with the previously intercoiled helix 5. The whole series of helices are thus rigidly
supported and will not collapse under moderate lateral pressure. The manufacture of
the fabric is continued by engaging or interlocking each alternate and intermediate
helix subsequently added respectively with the last two and the last three helices
of the partially made fabric; as for example in Figure 4 the helix 7 is intercoiled
or engaged with the helices 5 and 6 the addition of the last helix 7 increasing the
width of the fabric and in Figure 5 the helix 8 is intercoiled or engaged with
the helices 5, 6 and 7 but the last named helix 8 remains in the same line as
the helix 7. The next added helix will intercoil with the helices 7 and 8 and the
subsequent helix with the helices 7, 8 and 9 and so on until the desired width of
fabric is obtained.
The wire fabric thus made is finer or closer than fabrics made up of the same or
approximately the same number of helices interlocked in the ordinary way and the
helices of the said fabric are mutually supported.
Although I have described the making of the fabric by first taking a compound
helix of four single helices yet the making of the fabric may be commenced by a
compound belix of three single helices.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that I claim as
the said invention :-
The improved wire fabia

furniture, the seats of cycles, panels, wire belting and other articles; the said fabric
consisting of helices whose diameters bear to their pitch the ratio, or approximately
the ratio of 5 to 13, the said helices being interlocked or combined by taking a
compound helix consisting of three or four helices and intercoiling or engaging an
additional helix with the first and third helices and another with the first and third
helices and last added helix, the alternate and intermediate helices subsequently
added engaging respectively with the last two and last three added helices of the
partially made fabric substantially as hereinbefore described and illustrated.
