PROVISIONAL SPECIFICATION.
Improvements in Dog Muzzles.
I, WILLIAM GEORGE NORTHAM, of 77 Wellington Street, Woolwich, Confectioner,
do hereby declare the nature of this invention to be as follows:-
These improvements refer to the construction of dog muzzles in such manner as
hereafter described that while the animal is securely muzzled such freedom is allowed
as will enable the animal to drink or pick up pieces.
According to my invention I provide a spring head piece connected by a loop or
loops for the sake of lateral movement to the collar; this spring head piece extends
over the head and down to the nose frame which latter may be made of wire or other
suitable material; the spring is such that the animal is free to lift or lower the head
within certain limits without friction. The nose piece is connected to the collar by
jointed side pieces which may conveniently be made of thin flat metal and the jointed
side pieces connected to the nose piece are united together by a chin strap. By these
means there is no pressure on the head, the nose can be depressed and the mouth
opened sufficiently to allow the animal to drink, but the mouth is prevented from being
opened sufficiently to allow him to bite by reason of the chin strap, and the extent to
which the mouth can be opened is regulated to the greatest nicety by the length of
the chin strap.
The spring in the head piece may be inserted between two or more pieces of
leather or be arranged outside same or in any other convenient way and shaped to
correspond with the contour of the head.

COMPLETE SPECIFICATION.
Improvements in Dog Muzzles.
I, WILLIAM GEORGE NORTHAM, of 77 Wellington Street, Woolwich, Confectioner,
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 :-
These improvements refer to the construction of dog muzzles as hereafter described
and in such manner that while the animal is securely muzzled such freedom is allowed
as will enable the animal to drink or pick up pieces.
And in order that my invention may be clearly understood I will describe same
with reference to the accompanying drawing which is a perspective view of a dog
muzzle made according to my invention.
According to my invention I provide a spring head piece A. The spring portion a
flat spring, for example, may extend throughout the head piece or only a portion
thereof and the spring may be rivetted to the strap as shewn or applied in any con-
venient and suitable manner. This head piece A is connected by a loop or loops for
the sake of lateral movement to the collar B; this spring head piece A extends over
the head and down to the nose frame C which latter may be inade of wire, leather,
or other suitable material, the spring is such that the animal is free to lift or lower
the head within certain limits. The top of the nose piece or nose frame C is shewn
as made in a piece with the head piece A the material being split at the front and
connected to the nose piece proper C. This nose piece C is also connected to the
collar B by loosely jointed side pieces D, these loosely jointed side pieces D may be

pieces D are connected to the nose piece C by a chin strap C¹.
These jointed side
By these means there is no pressure on the head, the nose can be depressed and the
mouth opened sufficiently to allow the animal to drink but the mouth is prevented
from being opened sufficiently to allow him to bite by reason of the chin strap C and
the extent to which the mouth can be opened is regulated to the greatest nicety by the
length of the said chin strap C¹.
The spring in the head piece A may be inserted between two or more pieces of
leather or be arranged outside same or in any other convenient way and shaped to
correspond with the contour of the head.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In dog muzzles the spring head piece A in combination with jointed side
pieces D so as to allow the dog to raise or lower his head as and for the purposes set
forth.
2. In dog muzzles the head piece A continued beyond the nose or chin strap C₁ to
which it is fastened and split so as to form a cage above the nose of the dog but
allowing the extent to which the mouth is opened to be regulated by the nose strap C
in combination with the loosely jointed side pieces D substantially as and for the
purposes hereinbefore described and illustrated with reference to the accompanying
drawing.
3. In dog muzzles the loosely jointed side pieces D D as and for the purposes set
forth.
4. The dog muzzle constructed arranged and acting substantially as and for the
purpose hereinbefore described and illustrated with reference to the accompanying
drawing.
