Improvements in and connected with Metallic Travelling and
Conveying Bands.
We NATHANIEL GREENING, Managing Director, LINNABUS GREENING,
Managing Director and Secretary, and NATHANIEL GREENING & SONS
(LIMITED) Metal Perforators and Wire Manufacturers, all of Crown Street,
Warrington in the County of Lancaster, do hereby declare the nature of this
invention to be as follows:-
This invention relates to metallic and conveying bands and is designed to reduce
the cost of such bands.
The band constructed according to these improvements consists of a series of
parallel links each of which is constructed of wire bont in a zig-zag sinuous or
similar manner. These zig-zag links are connected together to form the band of
the required length. The meaus for the connection of the links may be various,
such as round or flattened rings, but it is preferred to employ spiral wires or
tubular rings. If spiral wires be used the turns of the spirals are caused to engage
with approximate bonds of two contiguous links so as to connect them together. The
connection of the links by means of the rings or short tubes may be effected by
folding the two links to be connected together, when the rings or tubes may be
passed along the zig-zags onrves or sinuosities to their propor positions.
Straight wires may also be employed for the purpose of strengthening the band
and for the purpose of breaking up the meshes formed by two links.
The ends of the links may be simply turned inwards or he so turned and
returned slightly above or below the plane of the link. In this case, the straight
wires may have their ends recurved and the recurved parts of them may be
inserted under the returned parts of the link wires. This will give the band great
rigidity in one direction while allowing it to bend freely in the other, whilst both
arrangements produce a strong safe selvedge.

COMPLETE SPECIFICATION.
Improvements in and connected with Metallic Travelling and
Conveying Bands.
We, NATHANIEL. GREENING, Managing Director, LINNAEUS GREENING,
Managing Director and Secretary, and NATHANIEL GREENING & SONS
LIMITED, Metal Perforators and Wire Manufacturers, all of Crown Street,
Warrington, in the County of Lancaster, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to he particularly
described and ascertained in and by the following statement :-
This invention relates to metallic travelling and convoying bande, aud is designed
to reduce the cost of such bands.
The band constructed according to these improvements consists of a series of
parallel links each of which is constructed of wire bout in a zig-zag sinuous or
similar manner, the links being suitably connected together to form a band of the
required length. The means for the connection of the links may be various, such

page_text: as round or flattened rings, but it is preferred to employ spiral wires or tubular
rings. If spiral wires be used tho turns of the spirals or some of them are caused
to engage with approximate bends of two contiguous links so as to connect them
together.
Straight wires
may also be employed transversely for the purpose of strengthening
the band and for breaking up the meshes formed between two links.
We will more particularly describe our said invention with reference to the
accompanying drawings in each of the figures of which similar parts are denoted by
similar letters of referonce.
Figure 1 shows in partial plan and in partial side view respectively, the
construction of a band with zig-zag links connected by spiral wires.
Figure 2 shews in similar views, part of a band having its links connected by
short tubos or rings.
Figure 3 represents a modification of the band illustrated in Figure 1.
Figure 4 shews two further modifications.
In all the figures A ropresents the zig-zag or similar wire links, and B the rings
tubes or spiral wires employed to connect the links together.
The zig-zag links in the form represented by Figure 1 aro connected together by
spirals which may have right hand and left hand twist in alternate spirals, and
may have a sharper or quicker pitch at tho points of connection as shown. These
spirals strengthen the band and break up the lozenge shape meshes which would
otherwise exist between the links. The wire at the end of each spiral or ench
alternato spiral may be turned down along the edge of the bolt so as to form a
straight selvedge S, and be fastened off at the next spiral or next spiral but one as
the case may be.
As illustrated by Figure 2, the links are formed by bending the wire at right
angles to the form shewn. If these links be conuected by short tubes as shown in
the upper part of the figure, the tubes may suitably fill the space between two
successive bends of the wire as shewu, as this will give lateral stiffness to the band.
If wire rings bo employed as shewn in the lower part of the figuro, they may bo
arranged to connect the links by tho angles as ropresented.
In the part of a band shewn by Figure 3, links similar to those shewn in
Figure 1 are used, and they are connected by a zig-zag or spiral wire of slow pitch
which engages with the angles of the opposed links. If desired, a similar wiro
with a quicker pitch may be used and engage with the angles of the links at
alternate or each third or other turn. The upper part of Figuro 4 resembles
Figure 3 in all respects oxcept that the angles of the links are twisted to form
loops through which the means of connection is passed. The lower part of
Figure resembles the upper part except that the links are connected by rings
instead of a spiral.
A rod R as in Figura 2 or a stretcher R' as in Figure 4, may be employed at
suitable intervals across the band. Such rods or stretchers may be connected to
the links by any suitable means, and are only used in cases where it is desired to
provide against longitudinal stretching or transverse bagging of the bands, or
to break up the meshes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declaro that what we
claim is :-
1. A travelling or conveyor band, consisting of a series of links composed of
wires in zig-zags or the like, connected together by means of rings tubes or wire
spirals, substantially as hereinbefore described and as illustrated by the accom-
panying drawings.
2. In a metallic travelling or conveyer band, links constructed of wire bent and
re-bent in a zig-zag or similar manner, substantially as hereinbefore described aud
as illustrated by the accompanying drawings.

bereinbefore described and as illustrated by the accompanying drawings.
