IMPROVEMENTS IN SPRINGS FOR CORSETS, BED BOTTOMS, AND OTHER PURPOSES
Year: 1875

page_text: LETTERS PATENT to Henry Kellogg, of Milford, Connecticut, United
States of America, at present of 123, Chancery Lane, London, for
the Invention of "IMPROVEMENTS IN SPRINGS FOR CORSETS, BED BOTTOMS,
AND OTHER PURPOSES."
PROVISIONAL SPECIFICATION left by the said Henry Kellogg at
the Office of the Commissioners of Patents, with his Petition, on
the 20th September 1875.
I, HENRY KELLOGG, of Milford, Connecticut, United States of
America, at present of 123, Chancery Lane, London, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN SPRINGS
FOR CORSETS, BED BOTTOMS, AND OTHER PURPOSES," to be as follows:-
My Invention consists in employing one or more threads of iron,
copper, brass, steel, or other wire, from which I form one or more coils
by rolling them spirally around spindles or moulds, and I then pass
them between the rolls of a press in such manner that the spirals of

page_text: the coils are flattened together so that the spirals lie over and upon
each other, and a new kind of flat spring is produced, which is flexible
in all directions both in its length and breadth, or sidewise.
These-springs-may-be-employed for busks for corsets, hoops of
crinolins, springs-of-chairs, couches, sofas,-cushions,-bed_bottoms, and
other like articles, and will advantageously take the place of the plain
band spring in numberless cases where such band springs are required
to possess the property of being flexible in more than one direction.
According to the use to which these springs are to be put they will
be made in this or that metal, and of one or more wires of greater or
less thickness, that is, formed of a single spiral or cylinder treated as
herein-before described, or of two spirals or coils placed together so that
the spirals of one cylinder will penetrate laterally or lie between the
spirals of the other coil, and then passed through the rolls of the press
so as to form a flat spring.
When these springs are composed of two spirals or coils one of the
wires will be wound from left to right and the other from right to left,
so as to form the two spirals or coils in a contrary direction, for if this
condition is not observed the spring produced will have a tendency to
"buckle," but by forming the spirals right and left this tendency is
compensated.
When the springs are made they may be tempered and japanned, or

Letters Patent, bearing date the Twentieth day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Henry Kellogg, Her special
licence, that I, the said Henry Kellogg, my executors, administrators,
and assigns, or such others as I, the said Henry Kellogg, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN SPRINGS FOR CORSETS, BED BOTTOMS, AND OTHER PURPOSES," upon the con-
dition (amongst others) that I, the said Henry Kellogg, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months.next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Kellogg, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be. particularly described and ascertained in and by the
following statement (that is to say) :—
My Invention consists in employing one or more threads of iron,
copper, brass, steel, or other wire, from which I form one or more coils
by rolling them spirally around spindles or moulds, and I then pass
them between the rolls of a press in such manner that the spirals of
the coils are flattened together so that the spirals lie over and upon each
other, and a new kind of flat spring is produced, which is flexible in all
directions, both in its length and breadth, or sidewise.
These springs may be employed for busks for corsets, hoop of
crinolins, springs of chairs, couches, sofas, cushions, bed bottoms, and
other like articles, and will advantageously take the place of the of the
plain band spring in numberless cases where such band springs are required
to possess the property of being flexible in more than one direction.

be made in this or that metal, and of one or more wires of greater
or less thickness, that is, formed of a single spiral or coil treated as
herein-before described, or of two spirals or coils placed together so that
the spirals of one coil will penetrate laterally-or-lie-between-the-spirals
of the other coil, and then passed through the rolls of the press so as to
form a flat spring.
When these springs are composed of two spirals or coils one of the
wires will be wound from left to right and the other from right to left,
so as to form the two spirals or coils in a contrary direction; for if this
condition is not observed the spring produced will have a tendency to
'buckle," but by forming the spirals right and left this tendency is
compensated.

When the springs are made they may be tempered and japaned, or
colored or galvanized.
When these springs are used as busks for corsets, hooks or studs, and
eyes or loops are fixed therein, or a loop and hook is formed from the
wire of the spring.
Having now described the nature and particulars of my said Inven-
tion, I claim the improvements in springs for corsets, bed bottoms, and
other purposes, substantially as herein set forth.

In witness whereof, I, the said Henry Kellogg, have hereunto
set my hand and seal, this Eighth day of March, in the year
of our Lord One thousand eight hundred and seventy-six.
