fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Baron Charles Philip de Thierry, do hereby declare that the nature of my
said Invention, and the manner in which the same is to be performed, are
particularly described and ascertained in manner following (that is to
say:
b
My Bitt for Coach and Bridle Uses, which said Bitt I call the Humane
Safety Bitt, is made with an additional bar or port or mouth, which is so fitted
upon the two cheeks of the bitt as to slide thereupon or therein, and by the
action of the curb rein it can be made to slide on the cheeks or in the cheeks,
to separate itself from and recede from the other bar, port, or mouth which
goes across the horse's mouth in the usual manner, and is firmly united at the
two ends of the two cheeks of the bitt. The figure of my bitt is shewn in
the Drawing hereunto annexed, wherein Figure 1 is a front view and Figure 2
a side view. A, B, A, B, are the two cheeks of the bitt united firmly together
by,the bar, part, or mouth C, D, which lies across in the horse's mouth. His
the curb chain, which is hooked at each end to the two ends A, A, of the
cheeks. Now my Invention consists in the lower sliding bar, port, or mouth
E, F, which is not fixed to the cheeks, but is fitted thereupon or therein with
sockets to allow it to slide upon the cheeks, in order that it may either lie
close to the fixed bar C, D, as shewn in the Drawing, or it may be slided
down and separated therefrom in the manner shewn by the dotted lines G.
Two separate reins are to be used with my bitt, as shewn in Figure 3, but
both are are attached to the rings E, F, at the ends of the sliding bar. One
of the reins K. is carried direct from those rings to the rider's hand in the
riding bitt, and in like manner the bearing rein or gag rein is attached to the
driving bitt, and this rein the rider is to use as a snaffle or bridoon for
ordinary use. The other rein L is conducted through the rings B, B, at the
lower extremities of the cheeks, and this rein the rider is to use when the
horse requires a curb. In that case he must slacken the bridoon or upper
rein K, and then, by pulling the rein L, the lower or sliding port is slided
down or separated from the fixed one to the position of the dotted lines G,
in which state they occupy greater space in the horse's mouth, and they act
with great power in consequence of the leverage obtained by the rein drawing
from the lower extremities of the cheeks. When the rider does not wish
to continue the use of the curb he slackens the curb rein L, and draws the
other K; this returns the moveable bar again towards the other bar, so
that they occupy less space in the horse's mouth, and as the rein K/draws

page_text: from the rings at the ends of the bar there is no leverage. Hence, the
action is the same as a common snaffle or bridoon. Stops are fixed to the
cheeks to limit the sliding motion of the lower sliding bar or port. The
rein L may be rounded at the part where it passes through the rings B, B, or
a piece of fine curb chain may be substituted for that part of the rein which
runs through the rings B, B. When my bitt is for coach use it is constructed
in the same manner, but it is stengthened by a bar extended between the two
cheeks at the lower ends, as shewn by the dotted lines M.
In witness whereof, I, the said Baron Charles Philip de Thierry, have
hereunto set my hand and seal, this Twenty-eighth day of February,
in the year of our Lord One thousand eight hundred and twenty.
