page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
LE CAAN, of the Town of Llanelly, in the County of Carmarthen, Gentleman,
do send greeting.
WHEREAS His most Excellent Majesty George the Third, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Twenty-sixth day of February
now last past, did give and grant unto me, the said Charles Le Caan, my
executors, administrators, and assigns, His special licence, full power, sole
privilege and authority, that I, the said Charles Le Caan, my executors,
administrators, and assigns, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "CERTAIN APPARATUS TO BE ADDED AND UNITED TO THE AXLE-
TREES AND WHEELS OR NAVES OF WHEELS OF CARRIAGES, SO AS TO IMPEDE, RESIST,
OR CHECK THEIR ACTION;" in which said Letters Patent there is contained a
proviso, obliging me, the said Charles Le Caan, 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 two calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the samo
(relation being thereunto had, may more fully and at large appear).
NOW KNOW YE, that in pursuance of and compliance with the said
proviso, I, the said Charles Le Caan, do hereby declare that my said Invention
consists in causing the wheels, or either wheel singly, of any carriage what-
soever to be stopped or become stationary at the pleasure of the driver thereof,
by means of bolts or slides of iron, or any other metal or compound metal,

page_text: attached to an axletree of any kind or sort, which bolt or bolts, slide or slides,
by means of levers, with or without the assistance of springs, come into contact
with a plate of iron, or any other metal or compound metal, on which one or
more projections are formed, which plate or stop plate, being let in and fixed
to the nave of any wheel, will answer the purpose required by impeding the
motion of any carriage to the wheel or wheels of which the same is applied.
The said levers are or may be connected with the body of any kind of car-
riage, and to such part thereof as may prove most convenient, by either chains,
strings, cords, leather, or any other substance necessary for that purpose.
The Drawings in the margin of these Presents exhibit the apparatus as
usually applied to carriages. Figure 1 shews the bolt detached, with the manner
in which the lever (B) is applied. The bolt is shewn with a spring C, to give
it a recoil, but which I sometimes omit, as it is not very essential. Fig. 2
shews the situation of the bolt on the axletree. Fig. 3 is a cap, which is
screwed or fastened over the bolt, in the manner as shewn in Fig. 4, which 1
exhibits the Invention complete, as applied to two wheels. Figs. 5 and 6 shew
two rings of cast iron, which are fastened on to the nave of the wheel, and
have certain projecting or raised parts d, d, d, against which, in Fig. 5, the
bolt is driven when it is desired to lock the wheel of the carriage. Fig. 6 is
let into the nave of the wheel to steady and hold tight Fig. 5, when the bolt
is driven against it.
In witness whereof, I, the said Charles Le Caan, have hereunto set my
hand and seal, this Twenty-sixth day of April, One thousand eight
