COMPLETE SPECIFICATION,
Improvements in Muzzles.
OESTE
I, FRANÇOIS LOUIS ANTOINE CANARY, Manufacturer, of Draguignan, in the
Republic of France, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying drawing, that is to say :-
This invention has for its object improvements upon the ordinary systems of dog
muzzles, which are a source of great inconvenience and annoyance to dogs, and it
consists of a novel method of construction by which every facility is given to the
animal for eating and drinking without taking off the muzzle, and at the same
time perfectly protecting human beings or animals from being bitten by the dog
wearing it.
In the accompanying drawing, which is in illustration of my invention, Figures I
and 4 represent a side view of the improved muzzle in its position when the dog
has his jaws closed. Figures 2 and 5 represent a similar side view with the dog's
jaws open for the purpose of biting, and Figure 5 is a view of the muzzle from
below.
The muzzle is made of brass or iron wires or other suitable material, and is
passed over the head of the dog and fixed by two hooks a formed by the prolonga-
tion of the wires encircling its neck. At the lower part is arranged a double
frame pivoted at c in the muzzle. On this double frame rests a second frame d
which at one side slides freely between two guides in which it is kept by the
hooks e, and on the other side slides by means of the rings / between the frame b.
A flat spring which is fixed upon the cross support g constantly presses the
frame d upward.
The parts of the muzzle which touch the most sensitive parts of the dog's head,
may be covered with leather or cloth in order to prevent the animal from injuring
itself by the sharp movement which it makes to bite.
The operation is as follows:-The lower jaw of the dog rests upon the frame d
which when his mouth is closed is in the position shewn in Figures 1, 3, and 4.
When he opens his mouth, his lower jaw brings down the frame d which forces the
double frame forward, as shewn in dotted lines in Figure 1, and in its open
position in Figures 2 and 5. It will be seen by this movement that there is no fear
of injury from the dog but only a harmless blow from the frame g.
The improved muzzle allows the dog, although prevented from biting anyone, to
put his tongue out, to yawn, to drink, to take a piece of sugar or of bread, or even
a bone which he can gnaw without danger, whilst respiration remains perfectly free,
neither side of the head of the dog being held.
My improved muzzle is neither cumbrous nor unsightly, and it is easy to put on
and take off.
Having now particularly described and ascertained the nature of my said
invention, and the manner in which the same is to be performed, I declare that
what I claim is :-
An improved dog muzzle, consisting of a frame & turning upon a centre c, and
upon which rests a second frame d sliding at one side by means of two hooks e, and
on the other side by means of rings f, in the frame b, the frame being constantly
pushed upwards by a flat spring h, and the dog by the movement of its lower jaw

page_text: causing the frame d to rise and fall and thus bringing the frame to advance or
retire so as to prevent the dog from biting, substantially as described and shewn in
the drawing.
