PROVISIONAL SPECIFICATION.
Improvements in Initation Whalebone.
1, HENRY MANNING KNIGHT of 6 Stratford Place, Oxford Street, in the County of
London, Manufacturer, do hereby declare the nature of this invention to be as
follows
Imitation whalebone as heretofore made, is very liable to snap and break, the object
of my invention is to remedy this.
According to my invention the material used in the manufacture of imitation
whalebone is vulcanite or such kindred material, having inserted in same a strip or
strips. piece or pieces of strengthening material, and for this purpose I insert in the
vulcanite or kindred material strips or pieces of strengthening material of the length
of or about the length of the bones of imitation whalebone to be produced. The
strengthening material may be composed of wire. The imitation whalebone may be
conveniently made in blocks or sheets which are divided into strips of the thickness
and width required and in such manner that there is in each strip or piece produced
from such divided block or sheet a strengthening piece or pieces of the wire or other
material employed surrounded by vulcanite or kindred material and whereby the
whole structure is strengthened and consequently not so liable to break as heretofore.
The strengthening mater.al may be composed of wire alone or combined with textile
fabric or other suitable cores may be employed, and the cores may be made of any
convenient shape such as round, flat, undulated or of other form and shape, and may
be covered or not with textile fabric.
Imitation whalebone constructed according to my invention is applicable generally
to many purposes where whalebone has been heretofore used.

COMPLETE SPECIFICATION.
Improvements in Imitation Whalebone.
I, HENRY MANNING KNIGHT, of 6 Stratford Place, Oxford Street, in the County of
London Manufacturer, do hereby declare the nature of this invention and in what
imanner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
Imitation whalebone made from vulcanite as heretofore is very liable to snap and
break, now the object of my invention is to remedy this.
In the manufacture of artificial or imitation whalebone according to my invention
I use a material known as compounded rubber, vulcanite, ebonite, or such kindred
material and 1 insert a core in same composed of a strip or strips, piece or pieces
of wire alone or combined with some textile fabric. These strengthening pieces
should be of or about the length of the
56 bones of imitation whalebone to be
manufactured.
"
Figure 1 of the accompanying drawings illustrates in side sectional elevation drawn
on an enlarged scale such a piece of imitation whalebone constructed according to
this invention. a is the core or metal strengthening piece running from end to end
of the strip which latter is made of the compounded rubber, vulcanite, ebonite
or kindred inaterial and surrounds the metal core or strengthening piece a.
Figure 2 shows in sectional front elevation drawn on an enlarged scale a piece of
.מ

page_text: imitation whalebone when made in the manner before described and in external
appearance it resembles an ordinary strip of whalebone as used in the manufacture of
corsets, ladies dresses and for wearing apparel generally. The section of the metal
strengthening piece may vary-for example it may be circular rectangular or corrugated
but in all cases the rubber, ebonite, vulcanite or its kindred material must cover or
contain and hold within it the strengthening core. In the manufacture of such
artificial whalebone as the above we find the following method of manufacture to
answer the purpose well. We run out a thin sheet c of suitably compounded rubber
and on it lay, at apportioned distances the strips of metal as aforesaid as is shewn
in plan at Fig. 3. These again are covered with another thin sheet of rubber and
the whole is then vulcanized under pressure and in a high degree of heat.
The
sheet thus made, a section of which is shewn at Figure 4, is afterwards cut up into
strips of the desired widths and polished on a revolving buff when they are fit for
market.
A similar result is obtained by coating the metal strip with a very thin film of pure
rubber before inserting it between the sheets e, as above, but this is optional and does
not affect the general process. The metal strips may be coated separately being
separately covered with thin rubber compound or may be coated by single or repeated
dippings in rubber in a state of solution whereby it would adhere to the metal as
if painted on. The coating of the metal might be effected by hand or by running it
through a machine. In some cases the metal core may be of such section as to
dovetail into the rubber composition and in such case the rubber compound need not
entirely surround such metal core.
Imitation whalebone manufactured according to my invention is applicable to many
purposes where whalebone has generally been heretofore used.
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 that what I
claim is :-
First. In artificial or imitation whalebone the combination with a metal core at a of
compounded rubber, vulcanite b or kindred material round same substantially as and
for the purposes set forth.
Second. The herein described method of manufacturing artificial or imitation
whalebone, which consists in arranging strips of metal d at suitable distances apart
on a sheet of suitably compounded rubber e then covering with another sheet of the
rubber c then vulcanising the whole under pressure and in a high degree of heat and
afterwards cutting the sheet (enclosing the metal strips d) into strips; so that each
strip encloses a metal core, and finally polishing the strips whereby so called imitation
whalebones are produced which are pliant and are not so liable to crack or break as
hitherto.
Third. The herein described method of manufacturing artificial
or imitation
whalebone, which consists in coating the said metal strips separately by single or
repeated dippings in rubber in a state of solution, then vulcanising same under
pressure and in a high degree of heat and afterwards polishing the "bones
forth.
