page_text: PROVISIONAL SPECIFICATION.
We ISAAC CHORLTON of 19 Blackfriars Street Manchester in the County of
Lancaster, Spring mattress manufacturer and ALEXANDER LAWRIE of 55, 56 and
57 Bradford Street Birmingham in the County of Warwick, Wire worker do hereby
declare the nature of our said Invention for IMPROVEMENTS IN SPIRAL OR WOVEN
WIRE MATTRESSES AND OTHER SIMILAR ARTICLES CONSTRUCTED OF SPIRAL OR
WOVEN WIRES, to be as follows:-
The objection of this Invention is to facilitate the connection of spiral or woven
wire-work to the framework of the mattress or bedstead and to protect the raw
edges of such wire-work.
In carrying out our invention we employ one or more wires which are threaded
through the spirals or coils near the extremities or parts of the net work requiring
to be connected to the wooden or other framing-We then take a piece of Sheet
metal, say, sheet iron, brass, zinc, or other suitable metal and bend it round the
extremities through which the wires are passed so as to cover both sides of the
wire work and by then subjecting the sheet metal to pressure under a press or by
passing through rollers or dies we so press the spirals or coils together and form a
groove or grooves to cover the threaded wires that after being rivetted or otherwise
secured together, it becomes impossible to pull the wire work away from the shoet
metal.
This sheet metal edging also serves to connect extention or other springs to spiral
or woven wire net work by eyeletting or otherwise or to connect such sheet metal
ends direct to the frame work and is suitable for spring mattresses spring seating
or other similar articles constructed of spiral or woven wires.

Mattress Manufacturer and ALEXANDER LAWRIE of 55, 56 and 57, Bradford Street,
Birmingham, Warwickshire, Wire Worker do hereby declare. the nature of our
invention of "IMPROVEMENTS IN SPIRAL OR WOVEN WIRE MATTRESSES AND OTHER
SIMILAR ARTICLES CONSTRUCTED OF SPIRAL OR WOVEN WIRES," 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 facilitate the connection of spiral or woven
wire-work to the frame-work of the mattress or bed-stead and to protect the raw
edges of such wire-work.
And in order that this our said invention may be the more readily understood
and carried into practical effect we have hereunto annexed a sheet of drawings
illustrative of our improvements and will now proceed to describe the same with
the assistance of the letters of reference markod on similar parts in both views.
Fig 1 is a plan view partly in section and Fig 2 a side view of so much of the
end of a woven wire mattress as is necessary to indicato our improvements which
are applied thereto.
In carrying out our invontion we employ one or more wires a which are threaded
through the spirals or coils b near the extremities or parts of the net-work requiring
to be connected to the wooden or other framing.
We then take a piece of sheet metal, say sheet iron, brass, zinc or other suitable
metal and bend it round the extremities through which the wires are passed as
indicated by the letter c so as to cover both sides of the wire-work and by then
subjecting the sheet metal to pressure under a press or by passing through rollers or
dies we so press the spirals or coils together and form a groove or grooves b¹ to
cover the threaded wires that after being riveted or otherwise secured together by
the rivets d, it becomes impossible to pull the wire-work away from the sheet metal.
We prefer also to insert the wire a¹ at the bend of the sheet metal to improve the
appearance and strengthen the extreme edge.
This sheet metal edging c also serves to connect extension or other springs to
spiral or woven wire net-work by boles e drilled punched or otherwise formed in
such edging and which holes may be protected by eyelets for to connect such sheet
metal ends direct to the frame-work.
This improved edging is suitable for spring-mattresses spring-seating or other
similar articles constructed of spiral or woven wires.
Having thus 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
1st The method of protecting the raw edges and facilitating the connection of
spiral or woven wire work to the framework of the mattress or bedstead
substantially as bereinbefore described and illustrated on the accompanying
drawings.

page_text: 2nd The use and application of a sheet metal edging in combination with the
insertion of wires through the coils as a means of protecting the raw edges and
facilitating the connection of spiral springs to spiral or woven wire mattresses and
other similar articles substantially as hereinbefore described and illustrated on the
accompanying drawing.
