PROVISIONAL SPECIFICATION.
Improvements in and relating to the Manufacture of Bakers'
Biscuit "Wires" or Wire Trays.
"
I, WILLIAM REID of 114 Candleriggs, in the City and County of Glasgow,
Wire Worker, do hereby declare the nature of my invention to be as follows:-
My invention has reference to and comprises improvements in the manufacture
of hand made flat steel cased biscuit "wires or wire trays, such as are used by
bakers either for hand use or for use on the ordinary travelling band or chains,
and in the means employed in such manufacture; such improvements producing
a "wire" of a much stiffer and durable nature than those commonly made by
means of machinery.
In carrying into practice my improvements, I take hoop or ribbon steel of the
requisite breadth, cut to the desired lengths and pass same through any ordinary
screw punching press fitted with an improved die and matrix in order to double
over the flat steel to form the groove or recess to receive and encase the edge of
the wire cloth forming the body of the "wire." The improved matrix would be
formed as a block having a groove rounded at bottom formed from side to side of
the required shape and of any convenient length and fitted with side guides, and
the die attached to the operating screw of the press, would be of a corresponding
shape. I prefer to shape the steel binding by the die, by passing same through the
matrix a portion at a time, and instead of completing the shaping at one operation
to do so by degrees, thus passing it through from end to end several times.
shaping the four pieces required for each rectangular "wire," I take the wire cloth,
cut to the required size and shape, lay it on a flat surface and placing a heavy flat
weight on top of same to keep it quite flat 1 fit the several pieces to the sides
pressing them close so that the wire cloth enters quite into the bottom of
groove. I then remove the "wire" and its binding steel casing to an ordinary
punching press and punch rivet holes at the corners and along each side through
both sides of the steel binding and the wire cloth. I then complete the "wire"
by riveting the whole together by ordinary rivets either by hand or power.

I, WILLIAM REID of 114 Candleriggs, in the City and County of Glasgow,
Wire Worker, do hereby declare the nature of my invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement in writing, reference being made to the accompanying
sheet of drawings and to the letters and figures marked thereon, that is to say:-

bakers either for hand use, or for use on the ordinary travelling bands or chains,
and in the means employed in such manufacture, such improvements producing a
"wire" of a much stiffer and durable nature than those commonly made by means
of machinery.
In carrying into practice my improvements, I take hoop or ribbon steel of a
requisite breadth, cut to the desired lengths, and pass same through any ordinary
screw pinching press fitted with an improved die A as shown in Figures 1 and 2,
and matrix B, in order to double over the flat steel to form the groove or recess to
receive and encase the edge of the wire cloth c forming the body of the "wire "C
a corner of which is shown in plan and end view in Figures 3 and 4 respectively.
The improved matrix would be formed as a block B having a groove B' rounded at
bottom formed from side to side of the required shape and of any convenient length
..and fitted with side guides B' and the die A attached to the operating screw of the
press would be of a corresponding shape. I prefer to shape the steel binding by
the die A by passing same through the matrix B a portion at a time, and instead
of completing the shaping at one operation to do so by degrees, thus passing it
through from end to end several times. After shaping the four pieces required for
each rectangular "wire," I take the wire cloth, cut to the required size and shape,
and after passing same between rollers to stretch and flatten it, though this is not
essential, lay it on a flat surface and placing a heavy flat weight on top of same to
keep it quite flat, I fit the several pieces of shaped steel D, Figures 4 and 5, to the
sides, pressing them close so that the wire cloth c as well as the end of the binding
steel D enter quite into the bottom of groove d' as shown in Figures 3 and 4.
I then remove the "wire" C and its binding steel casing D to an ordinary pinching
press and punch rivet holes at the corners and along each side through both sides of
the steel binding D and the wire cloth c. I then complete the wire C by rivetting
the whole together by ordinary rivets D¹ either by hand or power, the open end d
of the steel binding D being hammered or pressed inwards to finish the corners.
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 what I
claim is:
First. The mode of, and appliances for, manufacturing bakers "wires" or wire
trays all substantially as herein described and illustrated by the accompanying
drawings.
Second. In the manufacture of bakers "wires' "
or wire trays the use of the die
and matrix for shaping the binding steel all substantially as and for the purposes
herein described and illustrated, by the accompanying drawings.
Dated the 22nd November.
