Improvements in Muzzles for Dogs and other Animals.
We, EATON JOHN CALDBECK, of 6. Lexham Gardens, Cromwell Road, in the
County of Middlesex, Gentleman, FRANK SEPTIMUS DEVONTEAUX SCOTT, of 27.
Clements Lane, in the City of London, Engineer, and ROLAND HASTINGS, also of
27, Clements Lane, aforesaid, Gentleman, do hereby declare the nature of this
invention to be as follows:-
Our invention is designed to provide a muzzle capable of allowing a dog or
other animal wearing the same to open its mouth to the fullest extent, thereby
enabling it to freely yawn, but at the same time being just as effective in pre-
venting it biting persons as the ordinary muzzle at present in use.
In carrying out our invention we form the frame of the muzzle in two parts;
one being for the upper and the other for the lower jaw. These two parts are
suitably jointed near the neck strap, while the portions adjacent to the animal's
mouth are retained in position by one or more suitable springs. One or more
extensible rods and tubes or other equivalent means are fitted to the two parts
of the frame at or near the front of the muzzle so as to prevent the animal biting
anyone, but allowing it to open its mouth to the fullest extent when necessary.

Improvements in Muzzles for Dogs and other Animals.
We. EATON JOHN CALDBECK, of 38, Evelyn Mansions, Victoria Street, in the
County of London, but formerly of 6, Lexham Gardens, Cromwell Road, in the
County of Middlesex, Gentleman. FRANK SEPTIMUS DEVONTEAUX SCOTT, of 27,
Clements Lane, in the City of London. Engineer, and ROLAND HASTINGS, also
of 27, Clements Lane, aforesaid, Gentleman, 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:-
This invention is designed to provide a muzzle capable of allowing a dog or
other animal wearing the same to open its mouth to the widest extent thereby
enabling it to freely yawn, but at the same time being just as effective in pre-
venting the animal biting persons, other animals, or things, as the ordinary
muzzles at present in use.

page_text: In order that the invention may be easily understood reference is made to the
accompanying drawings, in which : —
Figure 1, is a side elevation of a muzzle constructed according to our inven-
tion, the open position being indicated by dotted lines.
Figures 2, 3 and 4, are fragment views of the extensible bar for the muzzle.
In carrying out our invention we form the frame of the muzzle in two parts (A)
and (B); (A) being for the upper and (B) for the lower jaw. These parts may
be formed of wire as shewn or they may be of any suitable perforated substance
or constructed in any manner and of any material suitable for the purpose.
The said parts (A) and (B) are suitably jointed together near the neck strap (C)
in the form of a hinge, and are retained in position by one or more suitable
springs made of metal, india rubber, or other suitable elastic material. These
springs allow the parts (A) and (B) to open when forced by the animal's jaws,
in opening its mouth, and cause them to again close immediately the force is
removed. I find that an india rubber band such as (D) connected in any con-
venient manner with the upper and lower parts of the frame at each side is
very suitable; they are durable, and also can be easily renewed when necessary
at a trifling cost. The springs can be arranged in any suitable positions either
at the sides or front of the muzzle.
The two parts (A) and, (B) of the frame are furnished with one or more suit-
able extensible bars or barriers arranged at or near the front of the muzzle so
as to prevent the animal biting any person, although allowing it to open its
mouth to the widest extent when necessary. These bars are formed in two
parts, one of which is connected with or formed on the upper and the other on
the lower part of the muzzle frame. One part, of the said bars, overlaps, tele-
scopes, or otherwise suitably engages the other part, in such a manner that when
the two parts (A) and (B) of the frame are open the bars extend accordingly
and maintain the effectiveness of the muzzle. The said bars are furnished with
suitable stop to prevent the two parts of same from becoming disengaged.
The bars may be constructed in various forms. In Figures 1 and 2 the por-
tion (E) of the bar is in the shape of a link secured to the upper part (A) of
the frame; the portion (F) which engages the link being an upwardly bent
loop made in the stiffening wire of the lower part (B) of the muzzle frame.
The movement of the said loop is limited by the length of the link the lower
end of which forms the stop. In Figure 3 two links are shewn, the one engag-
ing the other. Figure 4 shews one part of the bar telescoping in the other with
a spiral spring between two collars; one collar being on each of the parts, so
that the spring would have the effect of keeping the upper and lower parts of
the muzzle in contact in their normal position. Of course this spring may be
omitted and independent springs used.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
Firstly: A muzzle formed in two parts (A) and (B) suitably jointed or
hinged together and having one or more retaining springs and suitable bar or
bars, as and for the purposes herein set forth.
Secondly: A muzzle constructed in the manner and for the purposes sub-
stantially as herein set forth and as illustrated.
