minster, the Twelfth day of May now last past, hath given and granted unto
me, the said Thomas Lambe, my. executors, administrators, and assigns,
special licence, full power, sole privilege, and authority, to make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
during the term of years therein. expressed, my Invention of "AN IMPROVED
TRUSS FOR PERSONS, AFFLICTED WITH THE BUBONOCELE, AND OTHER RUPTURES;"¸in
which said Letters Patent there is contained a proviso, obliging me, the said
Thomas Lambe, 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

NOW KNOW YE, that I, the said Thomas Lanibe, in compliance with
the said proviso, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is particularly described
and ascertained in the Plan hereunto annexed, and the following description
thereof, that is to say:-
This truss should be made of the best German or sheer steel, and long
enough to go about three parts round the body, and tempered so as to spring

page_text: with ease and safety, with three brass buttons or knobs rivetted at the head of
the truss. Under the head of the truss are rivetted both a main and a counter
spring. In the head of the truss is also a hole, in which is a steel or iron
screw with a brass head, which goes through and screws into the counter
spring, and which screw, by being simply turned round, brings down the counter
spring and a slide, so as to make the bolster hollow, and of course is a security
to the rupture, and easy to the pressure. To the main spring is rivetted a
brass collar or swage, which has a brass slide or tube to hold a cork fixed in
the centre of the bolster of the truss. On the outside of such brass collar or
swage, is also fixed a cork sufliciently large to make a complent head to the
truss, in order to prevent any ill effect from the least disturbance to the
rupture, which may happen by any sudden motion of the body, as the main and
counter spring will return the rupture to its proper place. A, A, A, as marked
in the Plan, is the steel part of the truss; B, B, the head of the truss;
C, C, C, three brass knobs, rivetted to the head of the truss; D, the center
hole for the screw; E, E, the rivet holes for the springs; F, the circular hole
for the knob of the flat slide; G, the hole for the rivet of the flat slide or catch;
II, the flat slide or catch; I, the steel or iron screw, with brass head; J, the
hole in the counter spring for the steel or iron screw; K, the main spring,
with two rivet holes; L, the counter spring, with two rivet holes; M, the
brass collar for the main spring; N, the brass hollow slide; O, the cork for
the top of the brass hollow slide; P, the cork for the head of the truss; Q, the
leather strap rivetted to the truss; R, the rivet hole for the strap of the truss;
S, the holes to catch the brass knobs to fasten the truss round the body;
T, U, a brass swage and slide, which may be rivetted to the head without the
springs. The steel part of the truss, and part of the leather rivetted should bo
covered, and which may be done either with leather, dimity, Merseilles
quilting, or flannel, or any other kind of substance, so that it be made
perfectly easy to the body of the wearer. This truss may also be made to
keep the rupture perfectly secure without the springs at the head of tho
truss before mentioned.
In witness whereof, 1, the said Thomas Lambe, have hereunto set my
hand and seal, this Second day of June, in the year of our Lord
One thousand seven hundred and ninety-five, and in the thirty-fifth
year of the reign of King George the Third.
THOS LAMBE. (L.S.)
