COMPLETE SPECIFICATION.
Improvements in Muzzles for Dogs and other Animals.
I, ALEXANDER JAMES ELI, of the firm of Hughes, Eli, & Hughes, of
76 Chancery Lane, London, W.C. Patent Agent, du hereby declare the nature
of this invention (a communication to me from abroad by George Albertin, of
Valence, Drôme, France, Railway Inspector), and in what manner the same is to
be performed, to be particularly described, and ascertained in and by the following
statement, that is to say :-
My invention relates to improvements in muzzles for dogs and other animals,
and has for object so to construct the muzzle that while it effectually prevents
the dog or other animal, to which it is applied, biting; it yet allows free use of
the jaws as when yawning, and permits of free movement of the tongue as when
drinking.
And in order that this my invention may be fully understood and readily carried
into effect 1 will now proceed to describe same with particular reference to the
accompanying sheet of drawings, in which
Figure 1 is a side view of the muzzle, Figure 2 a front view, and Figure 3 a
plan.
Figure 4 shews the muzzle in perspective.
The muzzle is mainly composed of two side parts or pieces A and B (see
Figures 1 and 3,) hinged together at a. The two pieces A are connected by means
of the cross bar O, which serves to maintain the width or opening unchanged.
The pieces B are connected by cross bars and
9 r, the cross bar performing at
the same time a most important function, viz.: it opposes itself to the open mouth
of the animal, and consequently renders it unable to bite.
The front extremity of the upper part A terminates in a kind of receptacle C,
in which that part of the piece B, represented by the quadrilaterals m, n, q, q' can
move, and these movements are of course followed by cross bar q, it being
connected with it. A rubber band encircles the pieces A and B close to the
joint a, so as to close the muzzle automatically.
As will be seen particularly on reference to Figure 1, the upper part of the
muzzle, consisting of the pieces A and cross bar O, remains constantly fixed, i.e. it
reposes on the snout of the dog, the lower part, composed of the pieces B, and
cross bars and on the contrary is movable around the pivot a. The muzzle is
fixed by means of straps as shewn. As the animal opens its mouth the lower jaw
encounters the cross bar r of the part B which latter revolves around the pivots a
and cause the cross bar y to slide along the receptacles C. The extreme position
is indicated by the dotted lines B¹ q¹ Figure 1. In this extreme position, limited
by the length of the receptacles C, as in all intermediate stations, the cross bar
slid to the point q'opposes itself to the open mouth of the animal, and consequently
as aforesaid renders it unable to bite.
g
On the animal shutting its mouth, the movable part of the muzzle will return
from position B' q' to the normal one B q. This movement as stated above is
produced by means of the rubber band acting as an elastic force.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is
The improvements in muzzles for dogs and other animals, substantially as

page_text: and for the purposes hereinbefore described and shewn in the accompanying
drawings.
Dated this 28th day of March 1893.
