EXAMIN OF THE THROAT MOUTH AND OTHER PARTS RELATIVE TO THEM
Year: 1884

page_text: I ARTHUR HENRY VESEY of 8 Upper Bedford Place, W.C. a Civil Engineer do
hereby declare the nature of the above invention for EXAMINATION OF THE THROAT
MOUTH AND OTHER PARTS RELATIVE TO THEM to be as follows:-
An instrument consisting of a hollow ebonite handle to which is attached a piece
of German silver wire or other suitable material of convenient diameter and length,
the said wire being grooved on each side, the said grooves carrying two copper
wires which come through hollow handle and are connected to a small electric lamp
fixed on a sliding collar, and the connections with the lamp are made inside the
collar, the lamp is to be partly covered-& so covered, as to only allow the light
to impinge on various sized mirrors which are fixed to the aforesaid German silver
wire or other suitable material by means of a bayonet joint and is so arranged that
the said mirrors may be placed at any convenient angle, either horizontally or
vertically.
The lamp as before mentioned may be of any convenient form, spherical or
otherwise, and may be made detachable if required.
The wires as aforesaid running through handle and alongside the support (made)
of German silver wire or other suitable material, may be insulated from one
another and fastened together so as to form one wire apparently for portability.
The covering as aforesaid for lamp is to be coated with some non-conducting
material for heat such as asbestos or asbestos paint or any other suitable material
inside or out.
The collar to which the aforesaid lamp, is fixed may be made of any suitable
material such as ebonite or metal if the connections aro insulated on each side
inside the collar. The above instrument may be worked by means of any suitable
battery, and such battery may be either fixed to the handle or contained within it
or may be entirely separate & of small size so as to go into the pocket,

I ARTHUR HENRY VESEY of 8 Upper Bedford Place in the County of
Middlesex W.C. Civil Engineer do hereby declare the nature of my invention
for "AN IMPROVED LARYNGOSCOPE" and in what manner the same is to be
. performed to be particularly described and ascertained in and by the following
statement :-
According to this invention I form the instrument of a handle of ebonite or such
like material from which extends a stem carrying at its end an incandescent
electric lamp of the ordinary construction (that is formed of a carbon or other
filament enclosed in an exhausted globe of glass) but formed of extremely small
dimensions. The lamp globe I cement with plaster of Paris or like cement which
is a slow conductor of heat into a cylindrical holder of ebonite. Almost the whole
of the globe is embedded in the holder, the front end only of the holder being open
and from it issues the light of the lamp.
By reason of the lamp being thus surrounded with an outer casing of material
which is a slow conductor of heat it can without risk of injury to the patient by
burning be held over the top of the throat so as to illuminate it or can be used for
inserting into and illuminating other parts of the body.
The back end of the holder is formed so that it may be inserted and held
preferably by a bayonet joint attachment into a socket formed at the end of the
stem of the instrument.
Inside the socket the ends of the wire terminals of the lamp are made to come
into contact with the insulated wires which are led back through the stem and
through the handle and which at their ends are made to project from the end of
the handle so that they may readily be coupled to other insulated wires from a
battery. The battery may easily be made small enough to be carried without
inconvenience in a coat pocket and yet bo sufficiently powerful for working the
lamp.
A wire carrying a mirror at its end may be connected to the stem of the
instrument so as to hold the mirror close in front of the lamp at any desired angle.
Figure 1 of the drawing hereunto annexed shows a side clevation of a
laryngoscope made as above described. Figure 2 is a longitudinal section of the
lamp and its cylindrical holder.
A is an ebonite handle. B is a hollow stem preferably a hollow wire of German
silver extending from it. C is a cylinder of ebonite at the end of the stem Ba
wedge shaped slot is cut across its end to form a socket to receive a corresponding
wedge shaped projection at the back end of the lamp holder. D D are two metallic
tongues on opposite sides of the interior of the socket. The tongues are at the
ends of insulated wire conductors which are led through the hollow wire stem B
and handle A-the ends of these wires are made to project from the back end of the
handle as shewn so that they may readily be coupled to other insulated wires from
a battery. E is the cylindrical holder within which the small incandescent electric
lamp F is held by plaster of Paris or like cement. E' is a wedge shaped projection
at the rear end of the holder to fit within the socket C. The lamp is formed of
two conducting wires G G passing into a sealed and exhausted glass globe and

page_text: carrying within the globe a carbon filament which passes from the end of one wire
to the ond of the other. The other ends of the wires G G which are outside the.
glass globe form the terminals of the lamp and are led through the rear end of
the holder E and made to lie along the opposite sides of the projection E' as shewn
at Figure 2. H is a ring which can be turned freely around the socket C its rear
end is flanged inwards to prevent it from slipping endwise off the front end of the
Booket and at its front end it has a longitudinal slot formed in it tho back end of
which takes a right angled bend or nearly so. When the holder is pressed into the
socket the ring H is slipped forwards and a pin I which projects out from the lamp
holder E made to enter the longitudinal slot in the ring. When the ring H has
been slipped forwards as far as it will go and the pin I is at the bottom end of its
longitudinal slot a partial turn is given to the ring so as to make the pin enter the
alot's sideway branch. In this way the lamp holder is locked into the socket.by
what is called a bayonet joint.
Other means of securing the lamp holder into the socket might be adopted
I prefer however to use a bayonet joint attachment as above described as it is both
simple and efficient. When the holder is inserted into the socket the ends of the
wires GG are brought into contact with the two metallic tongues D so that a
current may be passed from them to the carbon filament.
Preferably I make the handle of the instrument to carry a small resistance coil
as shown at J so that any desired amount of resistance can be placed into the
battery circuit if the current from the battery is too strong and would otherwise
injure the carbon filament of the lamp but the resistance might be placed on the
battery if preferred or be omitted altogether. One end of the resistance coil is
coupled to one of the insulated conducting wires which are led out from the back
end of the handle. The other of these conducting wires is coupled to a metal
spring K. By pressing upon this spring it can be brought into contact with an
insulated metallic pin coupled to one of the wires leading to the lamp. The other
wire leading to the lamp is coupled to a metallic bar L along which a finger M can
be slidden. The finger rests against the resistance coil. If the finger be slidden
up to that end of the coil which is coupled to the conducting wire the circuit will
when the spring finger M has been pressed inwards be completed without passing
through any of the coils of the resistance-but by sliding the finger away from this
end any desired number of the coils can be brought into circuit. It will be seen
that the circuit is only completed through the lamp at the time when the spring
finger M is pressed inwards so that the circuit is only completed through the lamp
just at the time when it is required to be used. In this way all unnecessary
heating of the lamp and the casing by which it is surrounded is avoided.
N is a mirror hinged or permanently fixed at a given angle to the end of a
wire O this wire can be slidden endwise to and fro through a hole in a collar P
which surrounds the stem B so that the mirror can be set at any desired distance
from the lamp. The collar also is made capable of turning around the stem so
that the mirror may be set in any position desired.
For illuminating the throat the mirror should be set an angle and its upper part
be brought close up to the lamp as shown at Figure 1. When the instrument has
been passed into the mouth and the mirror held over the top of the larynx the
light of the lamp will be reflected down it whilst at the same time an image of
its interior will be reflected from the lower part of the mirror to the eye of the
observer.
The mirror might if preferred be carried by a stem entirely independent of the
stem which carries the lamp so that the lamp would be held in one hand and the
mirror in the other it is however far better to carry the mirror from the stem of
the instrument as above described.
By means of very small mirrors capable of being fixed at any angle the above
instrument might be utilised as a speculum for the vagina and rectum, and if the
aryngoscopic mirror be hinged the mirror night then be turned out of the way
and the car, nose and pharynx examined.
