page_text: I, FRANZ CARL GUILLEAUME, of the firm of Felten & Guilleaume, of Mülheim
on the Rhine, in the Empire of Germany, wire manufacturers, 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 :-
A foot-mat constructed according to this invention is composed of spiral wire ;
the several coils being arranged in two series crossing one another at right angles
and interlacing together.
In the accompanying drawings Figure 1 represents in plan a corner portion of
a foot-mat constructed according to my improved method; Figures 2 and 3 are
transverse sections on the lines A A and BB (Figure 1) respectively. Similar letters
of reference indicate corresponding parts in all the Figures.
The body of the mat is composed of the series of parallel coils a' a' a' &c.
intertwined with the series of parallel coils 61 63 63 &c., the one series crossing the
other at right angles. The twist imparted to the coils constituting one series is in
the opposite direction to that appertaining to those belonging to the other series.
Each side of the mat is furnished with a border-coil which I prefer to make slightly
larger in diameter; the extremities of the body-coil wires being twisted in such a
manner within the border-coils as to secure the latter to the body of the mat, and
at the same time to lock the several body-coils longitudinally in position.
In the illustration appended hereto, it will be observed that three convolutions
of each of the body-coils in the upper or a series engage with two convolutions of
each of the coils in the lower or b series, the coils of the latter being wider apart;
also that the obliquity of the twist given to the border-coil a differs in a
corresponding manner from that employed for the border-coil b. Such relative
formation and arrangement of the upper and lower series of coils is not, however,
essential; as the convolutions interlaced may be equal or unequal in number as
regards the respective series to which the coils appertain. By means, however, of
such a method of manufacture as that more particularly described and illustrated,
a larger quantity of wire is thrown into the upper surface of the mat, the
durability of which is thereby increased. Further, the lower side being somewhat
more open than the upper side, the escape of gravel or similar matter is facilitated.
Although in the accompanying drawings I bave shewn a portion of a mat suitable
for garden use as typical of my system of manufacture, it is obvious that the
invention is applicable as a covering for footstools and for sundry other purposes.

page_text: If preferred, one side may be furnished with a rod, which, being mounted in fixed
eyes, forms a pivot upon which the mat may be turned for the purpose of sweeping
beneath.
Having thus particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim
First, the improved manufacture of wire-mats composed of spiral coils arranged
in two series crossing one another at right angles and intertwining together,
the coils constituting one series being twisted in the opposite direction to those
belonging to the other series.
Secondly, in a mat constructed of spiral wire, securing the several coils forming
the body thereof by engaging their ends within the convolutions of the border-coils
and there twisting the same in such a manner as to fasten all the parts in their
proper relative positions.
