PROVISIONAL SPECIFICATION.
A New or Improved Metallic Fabric.
1, HERBERT JOHN HADDAN of the Firm of Herbert Haddan & Co., of 18
Buckingham Street, Strand,, W.C. London Civil Engineer, do hereby declare the
nature of this invention, a communication to me from abroad by Joseph Guillot
of 7 Quai des Brotteaux, Lyons, in the Republic of France, Belting Manufacturer,
to be as follows:-
The object of the present invention is to construct an endless metallic chain which
consists of the following parts.
Firstly of transverse flat bands of wire bent or curved in the same plane, secondly
of metallic spirals attached to these flat bands.
Said flat bands can be arranged in any form or combination of forms. The same
chain may be composed of flat bands of the same kind or of different kinds. The
spirals further may have a circular, oval or flattened form but the latter shape is
preferred.
The wire used for the flat bands may be of any cross section but it will mostly
be round. Also the spirals may have any sectional form, that' of a flat band
however is preferred.
The dimensions of the chain and all its parts are unlimited and the same may be
used as desired bare or filled or covered with one or more substances, such as gum,
paste, leather, textile fabric or the like. It is proposed to use the chain covered
with a gum or a paste and covered over with a layer of leather or textile fabric to
thus prepare it as a power transmission band or chain. For this purpose the chain
is to be laid out in any length and width, preferably with flat bands of round steel
wire, and circular spirals made of flat steel bands.
The chain thus made is passed under strong tension between two cylinders which
will compress it and thus flatten the spirals, it is then cut lengthwise in bands of
the required lengths and widths. In order to cover each of these with impermeable
gum or paste which will serve to completely insulate them, to prevent them from
oxidizing during use, to form a trimming between the empty spaces and finally to
permit of their joining the leather or exterior textile material forming the final
covering, they are passed through a reservoir containing these substances in a liquid
state. A sufficient quantity of the latter will after this procedure, adhere to them,
whereupon they are passed between two cylinders or rolls that will thus press the
substance into the empty spaces or links thereby equalizing the same on each
surface in a perfect manner. Any other process for accomplishing this could equally
well be employed. The chain or belt thus obtained is then finished by being
covered with one or more leather bands or textile material, wrapped around in spiral
form or applied lengthwise.
Finally to establish a complete connection of the three parts of the strap or chain
they may be passed between two cylinders, which will effect the sizing of the two
interior faces of the wrapping. The. paste as described above, may be prepared of
different products such as gutta-percha caoutchouc in the form of waste or of
recastings in short of any other material or composition which will attain the above
indicated object.

jointing the two extremities by means of a spiral.

I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan & Co. of 18
Buckingham Street, Strand, London, Civil Engineer, do hereby declare the nature
of this invention, a communication to nie from abroad by Joseph Guillot, of 7 Quai
des Brotteaux, Lyons, in the Republic of France, Belting Manufacturer, and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement:
The object of the present invention is to construct an endless metallic fabric which
consists of the following parts.--
Firstly, of transverse flat bands of wire bent or curved in the same plane :
secondly of metallic spirals attached to these flat bands.
Said flat bands can be arranged in any form or combination of forins. The
same fabric may be composed of flat bands of the same kind or of different kinds.
The spirals may further have a circular, oval or flattened form but the latter shape
is preferred.
The wire used for the flat bands may be of any cross-section, but it will mostly be
round. Also the spirals may have any sectional form, that of a flat band however is
preferred.
The dimensions of the fabric and all its parts are unlimited and the same may be
used as desired bare or filled or covered with one or more substances, such as gum,
paste, leather, textile fabric or the like. It is proposed to use the fabric covered
with a gum or a paste, and covered over with a layer of leather or textile fabric to
thus prepare it as a power transmission band. For this purpose the fabric is to be
laid out in any length and width preferably with flat bands of round steel wire,
and circular spirals made of flat steel bands.
The fabric thus made is passed under strong tension between two cylinders which
will compress it and thus flatten the spirals: it is then cut lengthwise into bands of
the required lengths and widths. In order to cover each of these with impermeable
gum or paste which will serve to completely insulate them, to prevent them from
oxidizing during use, to form a trimming between the empty spaces, and finally
to permit of their joining the leather or exterior textile material forming the final
covering, they are passed through a reservoir containing these substances in a liquid
state. A sufficient quantity of the latter will, after this procedure, adhere to them,
whereupon they are passed between two cylinders or rolls that will thus press the
substance into the empty spaces or links, thereby equalizing the same on each
surface in a perfect manner. Any other process for accomplishing this could equally
well be employed. The fabric or belt thus obtained is then finished by being
covered with one or more leather bands or textile material wrapped around in spiral
form, or applied lengthwise.
Finally to establish a complete connection of the three parts of the strap or fabric,
they may be passed between two cylinders, which will effect the sizing of the two
interior faces of the wrapping. The paste, as described above, may be prepared of
different products, such as gutta percha, caoutchouc in the form of waste or of
recastings, in short, of any other material or composition which will attain the
above indicated object.
The fabric may be made in an endless length, that is to say, without splicing by
jointing the two extremities by means of a spiral.
In the annexed drawings, Fig. 1 is a plan and Fig. 2 a section of the improved

page_text: metallic fabric. A represents the transverse flat bands of wire bent or curved in the
same plane B represents the spiral bands; C, D, E, F, G, H, and I represent alternative
forms of bands A.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The new or improved metallic fabric formed of wires or bands bent or curved
in the same plane, and other bands bent spirally and connecting the former bands
in the manner specified.
2. The improved metallic fabric formed as described and covered or set in a pasty
material as set forth.
3. The improved metallic fabric formed as described, set in a pasty material and
covered with leather or fabric facings as set forth.
