Figures 4 and 5 are modifications.
Reference being had to the drawings and the letters thereon, A, indicates a mat
composed of bars or sections, a, of one or more coiled wire helices, and intervening
sections, b, of bent wire with which the bars or sections, a, are connected by inter-
twining, as shown.
The mat shown in Figures 1 and 2 is designed for indoor use, such as halls or
vestibules, and is made thin so that a door will readily pass over it in opening and
closing. The bars or sections, a, in this instance are made of several thicknesses of
coiled wire helices intertwined and of a width to suit circumstances, varying from
one half of an inch to an inch or more.
These
The wire helices are coiled in the usual manner and intertwined or screwed into
each other as they proceed from the machine, and the strand or strands forming the
edges of the bar are intertwined or screwed into the sections, b, of bent wire. The
sections, b, serve to separate the bars, a, and form an open fabric through which
the tiling or oilcloth or carpet in a hall or vestibule may be readily seen.
sections, b, may be bent to form eyes, c, as shown in Figures 1, 2, 3, and 4, or they
may be in the form of a helix flattened, as shown in Figure 5. It is obvious that
the configuration of these uniting and separating sections may be greatly modified,
and we do not, therefore, limit our invention to any especial form into which the
wire may be bent.
The ends of the mat may be protected and finished by encasing the ends of the
sections, a, and b, in a transverse bar, d, of rubber or equivalent material, such as
gutta percha or linoleum, which forms protection against the fabric of ladies'
garments catching on the jagged ends of the metal. This rubber bar, d, is applied
by the use of a mould, and the rubber is embedded in the interstices of the wire
fabric of which the mat is composed, while the rubber is in a plastic state, and is
subsequently vulcanized.
The mat thus constructed may be rolled transversely as shown in Figure 2, so as
to be readily and easily handled and transported.
For some purposes, such as railway and street cars, we may make the bara, a,
of one or more sections of coiled wire, as shown in Figures 4 and 5, or several
sections may be intertwined in the same horizontal plane and the bars separated
and held together by the sections, b.
For indoor purposes, such as halls, stairs, railway, and sleeping cars, where
ornamentation is desired, the mats may be made of different kinds of metals, such
A

page_text: as steel and brass or copper, the bars always being of the hard metal as they are
subject to the greatest wear.
For out-door mats a rubber wiper, e, having roughened or serrated edges, ff,
and a roughened or serrated upper surface, g, is applied. This wiper is embedded
in the body of the mat and projects above the surface of the mat to afford
convenient means for removing any offensive matter from the soles and edges of the
sole and heel of a boot or shoe. The wiper may be attached in any desirable part
of the mat, and in large mats two or more wipers may be applied. The wipers are
formed in moulds and embedded in the mat while in a plastic state and subsequently
vulcanized.
The out-door mats may be made of a continuous sheet of intertwined coiled wire
helices of one or more thicknesses, the coils crossing the mat and the ends secured
by interlocking.
The mat constructed as shown is very light and pliable, capable of being made in
great lengths and rolled for packing, handling, or transportation, while it is highly
ornamental and performs all the service of the thick, heavy and unwieldy metallic
mats now in common use.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1st. A wire mat composed of bars of coiled wire helices separated by intervening
sections of strands of wire connected to said bars.
2nd. A wire mat composed of bars of a plurality of intertwined coiled wire
helices and intervening sections of strands of wire with which the bars are
connected.
3rd. A wire mat composed of bars of coiled wire and intervening sections of
strands of wire having their ends embedded in flexible material.
4th. A wire mat composed of bars of coiled wire helices and intervening sections
of strands of wire having eyes or loops formed therein with which the bars are
intertwined.
5th. A wire mat composed of bars of coiled wire helices of one metal, and inter-
vening sections of other metal and of a different colour.
6th. A wire mat provided with a wiper of rubber or equivalent material
incorporated in the body and projecting above the surface of the mat.
