COMPLETE SPECIFICATION.
An Improvement in Wire Doormats.
J FRED ROWCLIFFE of Levenshulme near Manchester in the County of
Lancaster, 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 that class of wire doormats which are formed by inter-
lacing spiral wires secured in a metal frame.
The objects of the invention are to improve the appearance and increase the
efficiency of such spiral wire doormats.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof.
Fig. 1 on the drawings is a plan view of part of a spiral wire doormat made
according to my invention and Fig. 2 is a transverse section of a portion thereof
drawn to an enlarged scale.
In making doormats of this description it has hitherto been the invariable
practice to use wire spirals or coils of the same dimensions throughout and hence
the working surfaces of all the coils have been always on a dead level and the
scraping or cleaning effect has been more or less confined to those portions of the
sole and heel of the boots and shoes which are flat and rest upon the ground when
standing, whereas the parts of the same which are more or less hollow and do not
actually rest upon the ground when standing are those which retain the greatest
quantity of mud or soil, and which in fact require most cleaning.
In order to remedy this defect I propose to interlace together spirals or coils of
wire of different diameters as seen at Fig. 1 thereby forming on the surface of the
mat a series of alternate ridges and furrows. This is clearly illustrated on Fig. 2
the ridges being formed by the coils a of large diameter and the intervening furrows
consisting of the coils of smaller diameter so as to produce a ribbed cffect; which
as above described will be found to be much more effective than the plain surface
hitherto employed, as well as having an improved appearance.
Or instead of interweaving coils of different diameters flattened coils and round
coils may be employed which will have the same effect of forming ridges and
furrows on the mat.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. In spiral wire doormats of the class hereinbefore referred to the com-
bination of spiral wire coiled of different diameters or form in such a manner as to
form a ridge and furrow or ribbed effect as hereinbefore described.
Secondly. I claim as a new manufacture doormats made from spiral wire coils of
different diameters or form so interlaced as to present a surface consisting of
alternate ridges and furrows substantially as herein before described and illustrated
by the drawings annexed.
