Complete Specification Left, 1st Oct., 1888
Complete Specification Accepted, 2nd Nov., 1888
I, FREDERICK BROOKHOLDING JONES, of No. 31 Humberstone Road Leicester
in the county of Leicester Veterinary Surgeon, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in surgical and medical appliances for use in
Tracheotomy being an improvement upon the Letters Patent granted to me, and
numbered 5845 of the year 1887, for "Improvements in Tracheotomy Tubes," the
outer tube of which is provided with holding wings expanded, or opened out by the
insertion of the inner Tube."-I obviate this, in this invention by constructing
instruments having an outer casing, in segments, or sectional split tube, cach segment
being provided at their lower ends with expanded wings, and by one section fitting in
the other they are at once in position before the inner tube is inserted, as hereinafter
described. The object of this my invention is to facilitate the employment of
Tracheotomy instruments to render them more easy of adjustment and can be more
readily, and with more despatch inserted in, or taken out of the windpipe of an
animal or human being than is now the case, and a larger inner tube, clear of any
projections on its inner face, so that there is no danger of anything becoming lodged,
or accumulating therein, and providing a free passage for the supply of air to the
lungs-to effect this-I construct the instrument in the following manner.
I provide
the outer casing, which is tubular, and in sections, each section carrying an extended
wing, which are not cramped round like horns but arched and extended in a transverse
direction their outer edges being rounded off the section to be placed first in the
wind pipe is provided at its upper end with a collar, disc, or plate, and thumb screws
et in the upper face thereof, opposite to each other-one half the opening in the
centre being slotted wider than the half carrying the split tube and extended wing, to
receive the other section, the seguents fitting together to encase an inner solid tube
the arc, disc or plate of the second segment of the outer casing does not cover the
whole of the lower disc, one side being cut short to clear the thumb screw coming on

page_text: that side, to allow it to be more easily placed in position in the windpipe, but is slotted
to be put on the thumb screw on the opposite side, when by putting the notches cut
out in each disc or plate in a juxtaposition to each other, when it is seen, they are
properly adjusted with the holding wings extending in opposite directions-I then
provide an inner solid tube the length thereof of which is shaped to correspond with
the base, or inner end of the holding wings, but the portions of the inner tube
coming between the base or inner ends of the extended wings are longer, and have
their rounded points, so that they project a considerable distance into the windpipo,
sufficiently to prevent the rings of the windpipe collapsing and blocking up the ariel
space, so allowing of a greater quantity, and free access of the air to pass in and out
of the windpipe which is not accomplished by old instruments now in use, the said
inner solid tube is provided with a collar, disc, or plate conforming or thereabouts with
the others, except that it is smaller in circumference to allow of it being easily taken
hold of, having slots cut through to fit the heads of the Thumb screws as the collar is
put on, when this is done the screws are turned over the slots, and the plates or disc's
are firmly locked or fixed together in their required position-A plug is then fitted
into the opening of the inner tube to prevent anything from entering the windpipe
during rest, which is held firm by coming against a projecting stud placed in line
with the opening in the outer face of the upper disc or plate. AV shaped notch
being cut in the rim of the lid, when by bringing this opposite the stud, the plug can
be removed at will, but it cannot become displaced in any other way. To adopt the said
appliance for human beings the construction of the several parts are the same, only
smaller, by this my invention a larger amount of air, and an uninterrupted supply is
conveyed to the lungs, without the rattle or whistle occasioned by instruments now in
use with narrower openings when the animals are galloping or persons are execising.
The inside of the inner tube being quite clear, and easily cleaned out, as occasion may
require. I do not confine myself to the collars, disc's or plates being round, or oval,
they may be of any suitable shape, and of any suitable material, such as white metal,
Silver, Gold, or a composition of aluminium and the like.

I, FREDERICK BROOKHOLDING JONES, late of No. 31 Humberstone Road now of
No. 53 London Road Leicester, in the county of Leicester, Veterinary Surgeon,
Member of the Royal College of Veterinary Surgeons, London, 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:-
:-
My invention has reference to improvements in surgical and medical appliances;
for use in Tracheotomy being an improvement on and a further research in Instruments
for use in Tracheotomy, or Tracheotomy tubes-and a further improvement upon the
Letters Patent granted to me for "Improvements in Tracheotomy tubes" numbered
5845 of the year 1887, those tubes requiring that the flaps or wings of the outer tube
were only expanded or opened on hinges by the insertion of the inner tube.
By this new invention I do away with the hinged flaps, and projections of any kind
upon the inside of the instrument, as will be seen by reference to the drawings
accompanying this specification and to which I will now refer.
Figure 1. is a representation of and a front top view of the first section, or half of
the outer tube, (1,) with the extended lip or wing A. shaped or arched to fit the rings
of the windpipe, the collar, disc or plate carrying the thumb screws a¹ inserted
opposite to each other, about half of the opening being cut larger at a³ to receive the
second section, to form the outer tube.
Figure 2. is a flat top view of the second section, (2,) or remaining half of the
outer tube, having the extended lip or wing B, and the collar, disc or plate slotted
at 61 to fit on to the thumb screws in the first section, it will be observed that this
collar, disc or plate is cut short at 62 so that in fitting to the first section it is clear
of the one thumb screw and enables the second section to be inserted in its proper
position in the windpipe or taken out again quickly.
Figure 3, is a flat top view of the solid inner tube C the circumference of the
disc thereof being roughened or milled so that a firm grip can be obtained while being
inserted in the outer sections, the slots in the collar, disc or plate fit over the thumb
screws a¹, whereas the stud or button d³ secures they plug D in position.
Figure 4. is a side view of the inner tube shewing the extension of the barrel,
which is cut out to form the two lips c¹.
Figure 5. is a side view of the plug D to fit in the inner tube C the slits in the
barrel thereof, d' allow of it to be adjusted tight, or slack in the opening of the
inner tube the notch in the rim of the plug, d is to allow the plug to pass by
the stud or button d³ and by turning the plug round the rim comes under the said
stud or button so that it cannot be displaced except by again turning the notch under
the stud or button.

page_text: Figure 6. is a side view of the instrument put together consisting of the first and
second sections 1, and 2,-forming the split outer tube with the extended lips or
wings A and B, with the inner tube C placed therein in their relative positions, the
whole to be secured by turning the thumb screws a', the outer ridges E and rings el
representing a longitudinal section of the windpipe and shewing that the lips A and B
come close to the rings of the windpipe the walls of which they fit to their natural
shape thus avoiding the irritation occasioned by bad fitting instruments-c¹ denotes
the actual position of the lips of the barrel of the inner tube when inserted in the
windpipe.
The instrument is inserted after a circular portion of the windpipe has been taken
out, in the following manner, the tubular outer section 1, is first placed in the incision
in the windpipe then section 2, is introduced through the disc of the other and so
forms the outer tube, the solid tube c is then pushed in between the split sections 1,
and 2, and forms a complete tube, the slots b' in the sections 2 and C coming over the
head of the thumb screws a¹ and by turning these across the slots all the sections are
firmly secured in their proper positions, each of the plates or disc's having a notch on
its circumference so that when the instrument is put together properly the notches are
in a juxta position to each other, the concave portions of the barrel of the inner tube (
are flush with the curved part or base of the lips A and B, the lips e¹ of which extend
a considerable distance into the wind pipe in order to prevent the rings of the windpipe
collapsing and blocking up the aerial space after being worn for a long period, the
plug D placed in the inner tube C prevents anything from entering the windpipe.
By this invention when the instrument has been inserted in the windpipe and
properly adjusted it will retain itself in its true position without the aid of supports,
or straps or tapes round the neck.
The instrument will not diminish the natural size of the windpipe inside in the
slightest degree, the small arched lips or wings A and B of the outer tube are the
only parts in connection with the windpipe and so constructed that they fit the natural
shape of the windpipe without the slightest obstruction to the ingress or egress of
air to the lungs and the same thing implies when the plug D is inserted and the
patient has to breathe in the ordinary way through the nose. By the employment of
a short tube of a large diameter a patient can obtain a sufficient supply of air to both
lungs even under severe exertion-without any distress in breathing.
The fact of the instrument being short in the barrel and large in diameter and its
opening being free of any mechanical obstruction obviates or prevents any accumu-
lation of mucous and a clear and short passage to the windpipe being afforded, the
mucous can be coughed up immediately, there being no canula or long tube projecting
down the windpipe as in old instruments that act like an heel trap and allows mucous
to congregate and accumulate round the canula, by my invention this is avoided at
the same time a copious and uninterrupted supply of air to the lungs is ensured.
The instrument only requires to be removed but seldom for cleaning purposes
whereas other instruments accumulating mucous have to be removed several times a
day to be cleaned, thus making my appliance a permanent one, and any horse that is
a bad roarer may live in perfect comfort with this instrument inserted in his throat,
and rendered most serviceable to his owner in any description of work.
The wearing of the instrument is free from all pain, and even the most nervous
animals when accustomed to it, allow it to be taken in and out without resistence,
they are made of the best material preferably of platinum, alluminium, gold, silver,
or other white or precious metal, or they can be made or moulded out of any suitable
composition or material adapted for the purpose of making tracheotomy tubes-the
instrument being in sections that are placed one in the other and locked together
inserted or taken out at will as herein before described, and instantly replaced in
position with the lips fitting to the windpipe accomplishes a feat which hitherto has
not been attained by any instrument now in use.
It will be readily understood that my appliances can be made of the size necessary
to fit in the windpipe of a human being, the parts all being made smaller, but a
larger tube is used than in instruments with a canula or long tube. By the

page_text: employment of instruments arranged and constructed as described a larger amount of
air and an uninterrupted supply is conveyed to the lungs without the rattle or whistling
noise occasioned by the use of tubes with narrow openings, or mechanical substances
blocking up part of the windpipe.
I do not confine myself to the shape of the instrument as shown in the drawings,
for the collars, plates or disc's may be oval, or pitched to the shape of the neck.
The tubes I also construct to conform to the varying thickness of neck and
cartilage of windpipe, but the lips c¹ of the inner tube extend into the windpipe, as
herebefore described and is invented purposely to prevent the collapse of any of
the rings of the windpipe even if the instrument is worn for a long period of time,
thus making the instrument a valuable invention for the purpose of Tracheotomy or
in the employment of Tracheotomy tubes.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
-
1st. In Tracheotomy tubes the employment of the large inner tube C with lips c¹
extending beyond the angles at the base of the sections 1, and 2, to prevent the
collapse of any portion of the rings of the windpipe.
2nd. The extended lips A and B. arched and fitting close to the walls of the
windpipe, adjusted in the manner as hereinbefore described.
3rd. Improvements in surgical and medical or veterinary appliances; for use in
Tracheotomy whether for human beings or animals by the arrangement and combination
of the several sections fitting together, the component parts 1, 2, C and D forming
the instrument, the whole secured in their relative positions and providing a wide,
uninterruped space for the free egress or ingress of air to the windpipe. Substantially
in the manner and for the purpose as hereinbefore described and set forth in the
drawings.

Improvements in Surgical and Medical Appliances for Use in
Tracheotomy.
I, FREDERICK BROOKHOLDING JONES, late of No. 31. Humberstone Road now of
No. 53 London Road Leicester, in the county of Leicester, Veterinary Surgeon,
Member of the Royal College of Veterinary Surgeons, London, do hereby declare
the nature of this invention and in what manner the same is to be perfornied, to be
particularly described and ascertained in and by the following statement:-
My invention has reference to improvements in surgical and medical appliances;
for use in Tracheotomy being an improvement on and a further research in Instru-
ments for use in Tracheotomy, or Tracheotomy tubes--and a further improvement
upon the Letters Patent granted to me for "Improvements in Tracheotomy tubes
numbered 5845 of the year 1887, those tubes requiring that the flaps or wings of
the outer tube were only expanded or opened on hinges by the insertion of the
inner tube.
"
By this new invention I do away with the hinged flaps, and projections of any
kind upon the inside of the instrument, as will be seen by reference to the drawings
accompanying this specification and to which I will now refer.
Figure 1. is a representation of and a front top view of the first section, or half
of the outer tube, (1,) with the extended lip or wing A. shaped or arched to fit the
rings of the windpipe, the collar, disc or plate carrying the thumb screws a¹
inserted opposite to each other, about half of the opening being cut larger at a³ to
receive the second section, to form the outer tube.
Figure 2. is a flat top view of the second section, (2,) or remaining half of the
outer tube, having the extended lip or wing B, and the collar, disc or plate slotted
at to fit on to the thumb screws in the first section, it will be observed that this
collar, disc or plate is cut short at 62 so that in fitting to the first section it is clear
of the one thumb screw and enables the second section to be inserted in its proper
position in the windpipe or taken out again quickly.
Figure 3, is a flat top view of the solid inner tube C the circumference of the
disc thereof being roughened or milled so that a firm grip can be obtained while
being inserted in the outer sections, the slots b¹ in the collar, disc or plate fit over
the thumb screws a¹, whereas the stud or button secures the plug D in position.
Figure 4. is a side view of the inner tube C shewing the extension of the barrel,
which is cut out to form the two lips c¹.
Figure 5. is a side view of the plug D to fit in the inner tube C the slits in the
barrel thereof, d allow of it to be adjusted tight, or slack in the opening of the
inner tube C the notch in the rim of the plug is to allow the plug to pass by
the stud or button №³ and by turning the plug round the rim comes under the said
stud or button so that it cannot be displaced except by again turning the notch
under the stud or button.

The instrument is inserted after a circular portion of the windpipe has been
taken out, in the following manner, the tubular outer section 1, is first placed in
the incision in the windpipe then section 2, is introduced through the disc of the
other and so forms the outer tube, the solid tube c is then pushed in between the
split sections 1, and 2, and forms a complete tube, the slots in the sections 2
and C coming over the head of the thumb screws a¹ and by turning these across the
slots all the sections are firmly secured in their proper positions, each of the plates
or disc's having a notch on its circumference so that when the instrument
together properly the notches are in a juxta position to each other, the concave
portions of the barrel of the inner tube C are flush with the curved part or base
of the lips A and B, the lips of which extend a considerable distance into the
windpipe in order to prevent the rings of the windpipe collapsing and blocking
up the aerial space after being worn for a long period, the plug D placed in the
inner tube C prevents anything from entering the windpipe.-By this invention
when the instrument has been inserted in the windpipe and properly adjusted it
will retain itself in its true position without the aid of supports, or straps or tapes

Tracheotomy whether for human beings or animals by the arrangement and combi-
nation of the several sections fitting together, the component parts 1, 2, C and D
forming the instrument, the whole secured in their relative positions and providing
a wide, uninterrupted space for the free egress or ingress of air to the windpipe.
