PROVISIONAL SPECIFICATION.
Improvements in or connected with Metallic Lattice Work or
Fencing.
I, BERNARD ERNEST WILLIAM SIFFKEN, of Forest Side, Buckhurst Hill in
the County of Essex, Accountant, do hereby declare the nature of my said invention
to be as follows:-
The object of this invention is to produce a cheaply constructed metallic lattice,
which while being in a contracted state for economical and convenient transport or
storage, yet is so constructed as to be easily and freely expanded, when required
for use, and this to an extent to suit the purpose of its application. A further
leading feature in the invention, is that I am enabled to utilise what has hitherto
been a waste or comparatively useless material.
According to my invention, and with the object first mentioned, I take metallic
strips, cut to equal lengths, and lay them parallel to one another, with a [corre-
sponding number of strips superposed upon the first set, and at a suitable angle
therewith the latter set of strips being also parallel to one another.
At each crossing point I form an aperture in the strips generally of somewhat
elongated form, and between the strips, at each crossing point, I provide a distance
piece or washer; the three thicknesses thus formed are connected by a rivet, or
other fastener.
By forming the apertures in the strips of the somewhat elongated form, I allow
a certain amount of play or means for the self adjustment of the said strips, and
by means of the washers, or equivalents, such as burrs, whereby the two sets of
strips (where they cross) are kept slightly apart, I am enabled to fold or contract
the lattice with greater facility than heretofore, and moreover I am enabled
to paint the lattice and afterwards contract it without damage to the paint
thereon.
The metal strips may of course be made specially for use in the manufacture of
such lattice, in various degrees of strength, but. with lattice constructed as I have
described same, I am enabled to utilize what has heretofore been a comparatively
waste material, viz. the strips or metal bands which are used for holding paper
bales, or for binding cotton bales or the like purpose.
By my invention I produce a lattice which is easily manufactured, can be readily
contracted for transport, and expanded for use, without damage to the paint,
enamel or other preservative coating that may be thereon.

Improvements in or connected with Metallic Lattice Work or
Fencing.
I, BERNARD ERNEST WILLIAM SIFFKEN, of Forest Side, Buckhurst Hill, ir
the County of Essex, Accountant, 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 :-
The object of this invention is to produce a cheaply constructed metallic lattice,
which while being in a contracted state for economical and convenient transport or
storage, yet is so constructed as to be easily and freely expanded when required
for use, and this to an extent to suit the purpose of its application. A further
leading feature in the invention, is that I am enabled to utilize what has hitherto
been a waste or comparatively useless material.
In order that my invention may be readily understood I have illustrated same in
the accompanying drawing, in which
Fig. 1 shews in side elevation partly in section, and Fig. 2 in plan sufficient of a
piece of lattice constructed according to my invention to explain same.
Fig. 3 is an enlarged section taken about the line X Y of Fig. 1.
Figs. 4 and 5 shew in transverse vertical section and front elevation respectively,
a modification hereinafter fully described.
Figs. 6 and 7 shew in plan and side elevation respectively, an arrangement
wherein fluted strips are employed.
According to my invention, and with the object first mentioned, I take metallic
strips A, cut to equal lengths, and lay them parallel to one another, with a corre-
sponding number of strips B, superposed upon the first set, and at a suitable angle
therewith, the latter set of strips B being also parallel to one another.
At the points where the strips A and B cross each other, I form apertures in
the said strips, generally of somewhat elongated form, and between the strips A. B,
at each crossing point, I provide a distance piece or washer D; the three thicknesses
thus formed are connected by a rivet E, or other fastener.
By forming the apertures C in the strips A B of the somewhat elongated form,
I allow a certain amount of play, or means for the self adjustment of the said
strips A B, and by means of the washers D, or their equivalents, such as burrs F
Fig. 4, whereby the two sets of strips A B, (where they cross) are kept slightly
apart, I am enabled to fold or contract the lattice with greater facility than
heretofore, and moreover I am enabled to paint the lattice and afterwards contract
it without damage to the paint thereon.
The metal strips may be of course made specially for use in the manufacture of
such lattice, and in this connection the strips may be as at Figs. 6 and 7 fluted
longitudinally, whereby great strength is obtained in proportion to the weight of
material employed, but with lattice constructed as I have described same, I am
enabled to utilize what has heretofore been a comparatively waste material, viz., the
strips or metal bands which are used for holding paper bales, or for binding cotton
bales or the like purpose.
By my invention I produce a lattice which is easily manufactured, can be
readily contracted for transport, and expanded for use without damage to the
paint, enamel or other preservative coating that may be thereon..
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 metallic lattice work or fencing composed of strins formed at their

page_text: crossing points with holes of elongated form, the front and back sets of strips
being distanced at such crossing points by washers, or by burring the edges of the
holes, and united by rivets or other fasteners, substantially as and for the purposes
described.
2. The general arrangement and construction of parts composing my improve-
ments in and connected with metallic lattice or fencing, and whereby comparatively
waste material, such as strips or bands which have been used for holding paper
bales, or for binding cotton bales or the like, may be advantageously utilized,..
all substantially as described and illustrated with reference to the accompanying..
drawings.
