Year: 1784

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHANIEL
JAMES, of the City of Bristol, Sadler and Truss Maker, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date the
Fifteenth day of November, in the twenty-fifth year of His reign, did give unto
me, the said Nathaniel James, His special licence that I, the said Nathaniel
James, during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and Town of Berwick-
upon-Tweed, and within all His Majesty's Dominions and Plantations abroad,
my Invention of "SPRING TRUSSES FOR RUPTURES ON A NEW CONSTRUCTION, BOTH
SIMPLE, DOUBLE, NAVEL, SIDE, AND INGUINAL;" in which said Letters Patent is
contained a proviso obliging me, the said Nathaniel James, under my hand
and seal, to cause a particular description of the nature of my said Invention;
and how the same is to be performed, to be inrolled in His Majesty's High
Court of Chancery within four calendar months next 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
Nathaniel James, do hereby declare that my said Invention of Spring Trusses

page_text: for Ruptures, both Single, Double, Navel, Side, and Inguinal, is described in
the manner following (that is to say):
The single truss has two plates. The inside plate plays on double-joint
hinges, and betwixt that and the outside plate is a spring placed and rivetted
to the outside plate, which always keeps the pressure more or less, as the
patient requires. The outside plate may be three inches one eighth long, and
two inches and an half wide at the upper part, and gradually decline to one
inch five eighths at the lower studd, or larger or smaller in proportion, upon
the same construction, as the case may require. It has two studds and two
staples, and an wire round the bulbous or lower part, with a waste bandage and
thigh strap, and the trusses are properly padded and covered with leather, silk,
or satin, as most agreeable.
The double truss has four plates, with two springs placed between the
plates. The inside plates play on double-joint lunges, and betwixt the outside
and inside plates the springs play, and are rivetted to the outside plate, and
a spring rivetted to both compressures at a proper distance, as the cause
requires, and is from seven inches wide to two inches and an balf, or of such
other size on the same construction in proportion as the case requires. The
outside plates have four studds and two staples, with two wires round the
bottom part, and it has a waste bandage and two thigh straps of linnen,
woollen, silk, or sattin, as most agreeable.
The navel truss is composed of two plates, the inside less than the outside,
and plays on four springs, which are rivetted to the outside plate, and which
springs play between both plates. There is a pivett which is fixed in the
center, and which plays in a hollow tube, with a stop shoulder at the bottom,
so that the head of the pivett checks the plate from moving off the springs;
and has also four studds of brass in the outside plate, and its form is round,
oval, oblong, sextagon, octagon, or any other form required, and it may be
made of any size, according as it may be wanted. It bandages as the patient
pleases.
The side truss is composed of two plates of an oval form, and plays on four
springs, having a pivett fastened to the outside plate, which plays in a hollow
tube, with a stop shoulder to the bottom of the tube, so that the head of the
pivett checks the plate from moving off the spring. It has four brass studds,
and the length and width as the cause requires.
The inguinal truss has two plates, and contains one spring. The inside
plate plays on double-joint hinges. The outside plate has two studds, two
staples, and a wire round the bulbous or bottom part, and is three inches
five eighths long and two inches wide on the top, and decreases to one
