PROVISIONAL SPECIFICATION.
Improvements in Flexible or Elastic Appliances for use as Draught
Excluders, Billiard Cushions, and for other uses.
I GEORGE HENRY HARRAP of the Hulme Hall Works, Manchester, in the County of
Lancaster, Mattress Manufacturer, do hereby declare the nature of this invention to
be as follows :-
My invention relates to material or to appliances partly composed of vulcanised
caoutchouc and has for its object principally to lessen the cost of the same. In a material
specially adapted for application to doors and windows to exclude or lessen draughts
of air a tube of vulcanised caoutchouc is enclosed within a folded strip of woven
material which is applied so that a projecting strip is left on one side to facilitate the
attachment of the material to the door or window or the frame of the same. In lieu
of the said tube I employ a spiral wire which is less costly than the said tube. For
the purpose I prefer to use tinned wire or wire otherwise protected to lessen the
tendency to oxidation. Ordinary steel or hard drawn wire may be used but in cases
wherein a great amount of flexibility or elasticity would be required I should use
hardened aud tempered steel wire. I propose to use coiled hardened and tempered
steel wire in the formation of billiard cushions. The wire of a suitable temper and
gauge would be coiled into a spiral of a circular form or of a suitable form in cross
section and be covered with woven material or with a suitable material or envelope.
Such cushions would retain their elasticity during extremes of heat or cold better than
the ordinary cushions.
I do not confine myself to the herein mentioned specific uses of the improved
material or appliances.

COMPLETE SPECIFICATION.
Improvements in Flexible or Elastic Appliances for use as Draught
Excluders, Billiard Cushions, and for other uses.
I GEORGE HENRY HARRAP of Hulme Hall Works Manchester in the County of
Lancaster Mattress Manufacturer 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 and accompanying drawing:
My invention relates to material or to appliances which are ordinarily partly
composed of vulcanised caoutchouc and has for its object principally to lessen the cost
of the same. In a material specially adapted for application to doors and windows to
exclude or lessen draughts of air a tube of vulcanised caoutchouc is enclosed within a
folded strip of woven material which is applied so that a projecting strip is left on one
side to facilitate the attachment of the material to the door or window or the frame of
the same.
In lieu of the said tube I employ a spiral wire which is less costly than the
said tube. For the purpose I prefer to use tinned wire or wire otherwise protected to
lessen the tendency to oxidation. Ordinary steel or hard drawn wire may be used but
in cases wherein a great amount of flexibility or elasticity would be required I should
use hardened and tempered steel wire. The manner in which I propose to manu-
facture the said material will be clearly understood when reference is had to the
accompanying drawing which represents a short length of material adapted to be
applied to doors and windows as aforesaid. In the said drawing a is the spiral
coil of wire and b is the woven material.

page_text: The strip of woven material is folded so as to enclose the wire spiral the
material being wide enough to permit of the two margins being brought together
and superimposed so as to form a double thickness of material as is clearly
apparent in the drawing.
I unite the two layers of material by means of a row of stitches c with the aid of a
sewing machine.
In some cases I render the material mere ornamental by the aid of a machine
which will produce ornamental stitches or of a braiding machine. I do not
confine myself to the uniting of the folds of material by means of a sewing machine
as cement might be used for the purpose if preferred. The woven material may
be of any desirable colour and nature. I may use the combination of wire spiral
and woven material for other purposes than for the exclusion of draught as for
example I propose to use coiled hardened and tempered steel wire in the forma-
tion of billiard cushions. The wire of a suitable temper and gauge would be
coiled into a spiral of a circular form or of a suitable form in cross section and
be covered with woven material or with a suitable material or envelope. Such
cushions would retain their elasticity during extremes of heat or cold better than
the ordinary cushions. I do not confine myself to the herein mentioned specific
uses of the improved material or appliances. In some cases leather might take the
place of the woven material.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The combination of wire spiral and woven material or leather substantially as
and for the purposes set forth and indicated.
J
2. A wire spiral a enclosed in a strip of material 6 formed and united together
substantially as and for the purposes set forth and indicated.
