I FREDERICK BROOKHOLDING JONES, Unity Street, College Green in the City and
County of Bristol, Veterinary Surgeon do hereby declare the nature of this invention
to be as follows:-
I manufacture my Invention of any suitable material and construct it with an inner
and outer tube to be distinguished in this Specification as number one tube and
number two tube.
The openings of these tubes are considerably larger than the opening of the ordinary
instrument.
Number two tube which fits into number one tube is slotted at its base which slots
are fitted with fixed sturts of wedged or other convenient shape. This tube is
provided with a broad collar piece or disc slotted to receive corresponding thumb
screws attached to a similar, though somewhat broader, collar piece or disc with which
number one tube is also provided.
The opening of number two tube is fitted with a plug provided with a fixed hook or
other convenient attachment, which catches upon a stud or corresponding holdfast
with which the said collar-piece or disc of number two tube is constructed. The said
plug when in position within the tube is secured therein by incans of the aforesaid
attachments.
The collar-piece or disc of number one tube is provided with a required number of
thumb screws.
The flaps hinged at its base are made broader than those of ordinary
construction and shaped more conveniently to avoid irritation to the wind pipe. These
flaps are also provided at their hinged parts with fixed sturts wedged, or otherwise
shaped, outwards at their tube ends causing them to recess from the sides of the said
tube when the flaps are closed.
The action of my said invention in operation may be thus described :-Upon
inserting the instrument, number two tube is first removed from number one tube.
Upon completing the insertion of number one tube, number two tube is then socketed
within it, passing into which, the aforesaid slots at the base of number two tube pass
over the hinges of the flaps which attach the latter to the base of number one tube and

page_text: also over the aforesaid sturts with which the flaps are fitted as described, and brings
the aforesaid wedged or otherwise shaped sturts at its base to bear upon the inner
sides of the corresponding ones attached to the flaps hinged upon the base of number
one tube, and upon number two tube being further pressed into position the aforesaid
sturts depress the flap sturts and by their leverage thereupon open the flaps within the
wind pipe of the animal operated upon. The collar-piece or disc of number two tube
is by the same operation pressed over the collar-piece or disc of number one tube, the
said thumb screws upon which pass through the aforesaid slots in the collar-piece or
dise of number two tube, the thumb screws are then turned and the whole instrument
is thereby locked firmly into position.
When the horse is at rest the aforesaid plug with which number two tube is
supplied is inserted in place and fastened by means of its aforesaid hook and button or
other holdfasts which prevents the passage of foreign substances into the animals'
windpipe and lungs.
This plug when in position is perfectly secure from being displaced by the
animals' movements or violent coughing. When the horse is in exercise this plug is
of course removed.
Instruments fitted with my Improvements are free from all the complications of
ordinary construction and by providing a larger opening, a freer passage of air is
afforded and the tube being clear throughout the accumulation of mucous and other
obstructions is obviated.
The aforesaid collar-pieces or discs of the instrument are made slightly different in
size (that of number one tube being the largest) to afford a distinct hold in reinoving
number two tube from number one tube for cleaning or other purposes while the
instrument is inserted and to prevent the instrument from drawing in the orifice of
the windpipe during the process of such removal.
Dated the 21st day of April 1887.

I, FREDERICK BROOKHOLDING JONES, Veterinary Surgeon Saint Augustines'
Chambers Unity Street College Green in the City and County of Bristol 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 :-
I manufacture my Invention of any suitable material or materials and construct it
with an inner and outer tube which I distinguish in my Specification and drawings
one from the other as "No. 1" Tube and "No. 2" Tube and in order that my inven-
tion may be fully described and ascertained I accompany my Specification with
drawings in which similar letters of reference indicate corresponding parts.
The openings of these Tubes may be larger than the opening of the ordinary
instrument to afford the ingress of a larger volume of air to the windpipe and lungs
of the animal in which it is inserted.
"No. 2" Tube fits within "No. 1" Tube and is slotted at its base on either side as
shown in G. Fig. 1 of the drawings to the centre of these slots is attached a lever or
sturt of wedged or other convenient shape.
H Fig. 1. This Tube "No. 2" is provided with a collar piece or disc J Fig. 1
slotted. KK Fig. 1 to receive corresponding thumb screws C C Fig. 3 attached to
a similar though somewhat broader collar piece or disc. B Fig. 3 with which No 1
Tube is also provided. The collar piece or disc of No. 1 Tube is made somewhat
larger than that of "No. 2" Tube as is shewn B and J Figs. 2 & 5 to afford seperate
lines and a distinct hold to the latter when withdrawing it from No. 1 Tube, when the
instrument is in position in the throat of the animal and to prevent any consequent
drawing or dragging of the instrument by such process which may otherwise occur in
the windpipe.

with which the said
"
The opening of "No. 2" Tube is fitted with a plug "A"
hook L"Fig. 4" which catches upon a stud D.
collar piece or disc of "No. 2" Tube is constructed. The said plug A "Fig. 4'
when in position within its Tube "No. 2" is secured thereby by means of the afore-
said book L and stud D as shewn in place "Fig. 5." The flaps E hinged at the base
of "No. 1" Tube Fig. 3 are made broader than those of ordinary construction and
shaped more conveniently to fit the walls of the windpipe and to avoid the irritation
occasioned by an ill-fitting instrument. The aforesaid flaps E are also provided at
their hinged parts with sturts or levers F "Fig. 3" projecting within the Tubo when
the said Haps are closed as shewn in "Fig. 3."
The action of my said invention may be described in operation as follows
Upon inserting the instrument "Tube 1" is first placed within the windpipe with
the flaps closed as shewn E" Fig. 3" after which "No. 2" Tube is socketed within it
during which process the aforesaid slots G "Fig. 1" at its base allow for the passage
of the said "No 2" Tube past the hinges N and sturts or levers F Fig. 3 of the
flaps E Fig. 3 of No. 1 Tube as shewn by G. G. Fig. 2 and brings the sturts or

page_text: levers H "Fig. 1" of "No. 2" Tubo to bear upon the inner or recessed sides of the
corresponding sturts or levers F "Fig. 3" which are attatched to the flaps E hinged
at the base of No. 1 Tube Fig. 3. Upon No. 2 Tube being completely pressed into
position within No. 1 Tube its aforesaid sturts or levers H "Fig. 1" being reversely
shaped or wedged to the sturts or levers F " Fig. 3" as already described pass at the
back of the latter and by their pressure and leverage thereon throw them outwards
from the sides of the tube and open the flaps E Fig. 3 within the windpipe of the
animal operated upon as shewn in Fig. 6 and fixes the complete instrument in position
as shewn in "Fig. 5" with the thumb screws (C locked. The collar piece or disc
of No. "2 Tube" J Fig. 1 is by the same operation pressed over and upon the collar
piece or disc B Fig. 3 of No. 1 Tube the thumb screws CC "Fig. 3
of which pass
through the said slots or eyes K K Fig. 1 in the collar piece of disc J of No. 2 Tube.
The said thumb screws are then turned which locks No. 2 Tube within No. 1 Tube and
the parts of each tube firmly together in combination as shewn by Fig. 2 of the
drawings. The plug A "Fig. 4 can be removed when the horse is in exercise as its
chief use is to prevent foreign substances from entering the animals windpipe during
its rest and absence of attention. The plug is perfectly secured by the aforesaid
attatchments or holdfasts L and D Fig. 5 from being displaced by the animals move-
ments or violent coughing.

Iustruments constructed by my improvements are free from all the complications of
those of ordinary construction and by their provision of a larger opening free from
obstructive mechanism a clear passage to the wind pipe is afforded and the accumula-
tion of mucous and other obstructions obviated while a copious and uninterrupted
supply of air to the lungs is ensured. The instrument is also free from the rattle
which the ordinary complicated and ill fitting instrument occasions by the animals
movements and it is not of such unsightly appearance.
To allow for any varying thickness of cartilage of different horses, I construct my
instruments of varying length in their tubes to meet such cases which however are
rare and inconsiderable.

tion and in
