Year: 1806

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
HINCHSLIFFE, of Dumfries, in that part of the United Kingdom called Scotland,
Surgeons Instrument Maker, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of His United Kingdom of Great
Britain and Ireland, bearing date at Westminster the Twenty-sixth day of
March, in the forty-sixth year of His reign, give and grant unto me the said
Joseph Hinchsliffe, my oxors, adñiors, and assigns, His especial licence, that
I, the said Joseph Ilinchsliffe, my exors, adñiors, and assigns, during the term
of fourteen years therein mentioned, should and lawfully might make, use,
exercise, and vend within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "A NEW METHOD OF MANUFACTURING ELASTIC SPRING
TRUSSES FOR RUPTURES, OR RUPTURE BANDAGES;" in which said Letters Patent
there is contained a proviso, obliging me, the said Joseph Hinchsliffo, by an
instrument in writing, under my hand and seal, to cause a particular description
of the nature of my said Invention, and in what manner the same is to be
performed, to be inrolled in His Majesty's High Court of Chancery within
one calender month after the date of the said recited Letters Patent, as in
and by the same, relation being thereunto had, may more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Hinchsliffe do hereby declare that my said Invention of a new method

page_text: of manufacturing clastick spring trusses for ruptures, or rupture bandages is
described and ascertained in manner following, that is to say :-
I
Take a piece of the best whalebone, known by the name of staymaker's bone,
of a proper size and length, viz., for a full-size truss about twenty-three inches
long, three inches broad, and one quarter of an inch thick, hold it over the
blaze of a large lamp or any other proper thing that will produce a sufficient
blaze so as to heat gradually, and keep turning it to every side, and moving it
from one end to the other, when it begins to burn on the edges it is nearly hot
enough, but it depends on the substance of the bone; it may easily be tried by
taking hold of it with any proper thing to prevent its burning you, and when it
is found perfectly supple so as to bend any way and not go back again, it is
hot enough; then fasten it round a block made to the shape or form the
spring should receive, and when it is perfectly cold it will remain so. Then
take a rough file, or rasp, or other proper instrument, and file or take off
all the burnt part of the edges, &c., until it is perfectly clean. If the bone
be good it will not break nor give way, the spring may be made as supple as
you please with the file, &c. The head on which the spring is fastened is made
of sheet brass or mixt metal, or composition of metal, perfectly hard from the
rollers, about the thickness of a new shilling, and pinned or otherwise fastened
on the spring with brass pins, or other proper fastenings.
In witness whereof I, the said Joseph Hinchsliffe have hereunto set my
hand and seal, this Tenth day of April, in the year of our Lord One
thousand eight hundred and six.
