PROVISIONAL SPECIFICATION.
Improvements in Trellis Work and other Wire or Light Iron Work.
We, ARTHUR WILFRED BREWTNALL and HERMANN WILLIAM BREWTNALL
both of 4 Cateaton Street, Manchester, in the County of Lancaster, Gatesmiths
and Wire Workers do hereby declare the nature of this invention to be as
follows:-
Metal wires or bars by preference of a flat ribbon section with rounded edges
are made into trellis work of a neat, strong and cheap character by halving
together the members at the places where they cross each other, the bars being
notched halfway down their width or thereabouts alternately on opposite edges so
that when put together the wires are interwoven and thus retain themselves in
position and give great rigidity to the whole structure the face of the work so made
being flush or nearly so.
In cases where it is more convenient not to interweave the wires or bars we slot
them on one edge only and hold them in place by burring over the edges of the
slot after the wires or bars are put together or by tying with wire or in other
suitable way. Scroll or other ornamental work, may be combined with the plain
trellis work.
This invention is also applicable to the manufacture of screen work and of all
articles in which wires or rods crossing each other have been previously held in
position by means of tying or lacing wires.
Dated this 27th day of September 1892.

COMPLETE SPECIFICATION.
Improvements in Trellis Work and other Wire or Light Iron Work.
We, ARTHUR WILFRED BREWTNALL and HERMANN WILLIAM BREWTNALL,
both of 4 Cateaton Street, Manchester, in the County of Lancaster, Gatesmiths and
Wire Workers 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:-
In this invention we make a square, diamond or other trellis-work of strip metal.
Fig. 1 of the drawings represents a piece of trellis work, Fig. 2 is an elevation of
the strips and Fig. 3 is a perspective view of same when made up.
The strips a, b are slotted out at a¹ a³ and b¹, b³ alternately on both edges, the
slots being at the points where the strips are crossed by the other strips thus
determining the size of the mesh. The slots are placed at alternate edges because
the work is put together with the strips going under and over each other and with
the slots coming opposite each other the surface of the work when finished is
perfectly level. To use a more technical description the strips being halved at
their points of contact make a flush surface in the work and are interwoven see
Fig. 3. The work is made ornamental by the insertion of scrolls c in the meshes
and this may be facilitated by cutting away some of the meshes in order to insert
scrolls of any desired size, as shown in Figure 1.

page_text: 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,-
1. The making of a trellis-work of strip metal in which the strips are inter-
woven and halved at their joints to fit closely and firmly together substantially as
described.
Dated this 24th day of June 1893.
