Anesthesia.
I, EMILE AUGUSTE GUILMETH of 24 Rue de l'Eveque Brussels in the
Kingdom of Belgium Merchant do hereby declare the nature of the said invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
The spray producer forming the subject of the present application has for its
object more particularly to facilitate the employment of au anaesthetic substance
which I denominate "coryl."
This substance which has the property of entering into ebullition at 0°, does
not permit of the employment, for its practical use in medicine and surgery of the
glass flask or the ordinary syringe or other analogous instruments.
It therefore became necessary to find a new mechanical means of great strength
and of easy manipulation to employ this new material.
The object of the present application is the apparatus which I have specially
devised for the above purpose and which I denominate "coryleur
""
My invention is illustrated in the accompanying drawings in which
Figure 1 is an axially sectional view of the apparatus,
Figure 2 is a side view showing the exterior of the apparatus.
Figure 2 is a horizontal section drawn on the line A B of Figure 2.
Figure 3 represents an apparatus which may be used either in a vertical or
inclined position.
Figures 4, 5, 6 and 7 represent various forms of cocks with movable valves
serving as regulators for the delivery of the material.
Figures 8, 9 and 10 are nozzles or month-pieces which are applied to the
regulators and which have forms appropriate to the part of the body to be
operated upon,
Figure 11 is a spray producing connection,
Figure 12 is a movable piece for holding the different nozzles,
Figure 13 is a view of the entire apparatus showing the method of charging
the same,
the product being received in a reservoir of special form and details
allowing of the charging of the "coryleur" or of the reservoir itself.
In all the figures like letters indicate the same parts.
The "coryleur" is composed of a reservoir A containing the "coryl." On this
reservoir is soldered a piece B upou which is arranged the valve cock C. In this
valve cock is screwed a stuffing box D in which the closing shaft or rod E
moves. This closing shaft which I shall denominate the "power closer," is only
used at the moment when the apparatus is about to be used and at the moment
the apparatus is finished with. It is provided with a key or handle having four
arms. One of these four arms marked in Figure 1, unscrews in order to be
placed on the stopper or air screw G Figure 2 the object of which will be hereafter
described.
.
The cock C has two passages H and I (Figures 1 and 24) the first of which H
is the outlet passage and the second I is closed by the stopper G.
At the upper
part of the cock C, is a movable rod J pierced with a hole j and provided at its
outer extremity with a button J. A pin K fixed to the rod and which slides in a
groove prevents any rotary movement so that when the button J' is pushed, the
hole j comes exactly opposite the conduit H of the cock C. At rest, the conduit H
Do7

page_text: is shut by the rod J which is brought back by a small coiled spring L. The rod J
carries a pin M the object of which is as follows. As the apparatus is being filled
by the conduit H during the time of the filling, the finger should be held on the
button of the rod J, it is in order to obviate this inconvenience that I add the stop
pin M, which moves in the same grooves as the pin K, excepting that it is longer
than this latter and serves to hold the shaft J down by means of the washer or
disc N. This washer or disc has a groove or recess (Figure 2) which gives
passage to the pin, but if the button is pushed and a quarter turn given to the
washer or disc this latter by not presenting its groove or recess before the pin M,
the latter cannot come back, and maintains the coryleur" open. Figure 4 shows
another arrangement of regulating cock which screws on to the cock C. It is
composed of a piece W which contains a valve X terminating in a spindle and
button, a small spring Y presses the valve to its seat. This arrangement has
besides the advantage that the pressure of the "coryl" adds itself to that of the
spring to close the valve X. In order to operate the tap, the button terminating.
the shaft of the valve is pushed. Figure 5 shows a simplified arrangement of the
same as do also Figures 6 & 7. In Figure 5 the cock is simply made in the
ordinary well known way. In Figure 6 the rod a carries at its lower extremity a
ring a capable of being folded back, in which engages the fore-finger of the
operator holding the apparatus, so that with a single hand he can graduate the
opening to give egress to the liquid. In Figure 7 the cock is opened by pressing
on the lever a hinged at a', and which, as soon as the pressure ceases, resumes its
resting or closed position by the action of the spring a". A hollow nozzle P
(see Figure 1) screws on the valve to project the liquid.
Qis the protection tube of the spray producer R placed above the nozzle and S is
a protection cap or stopper which is removed at the moment of using the apparatus
and which screws on the tube Q.
To fill or charge the apparatus the nozzle D is unscrewed after having
removed the parts which cover it, the "coryleur
is screwed on the "coryl'
reservoir Figure 13.
"
By means of the key F which has been previously removed from the spindle E,
the stopper is then unscrewed and in order to prevent it from being blown off by
reason of the pressure which might be left in the apparatus, a small hole V
represented in section at Figure 2A is pierced obliquely so as to give vent to the
gas before the stopper is completely unscrewed. When the apparatus is full the
coryl" is seen to escape by the hole in the stopper, this is rapidly closed and
the apparatus is ready for use.

The working of the apparatus is as follows:
To use the apparatus there are two positions, namely from below upwards, and
in an inclined position. The apparatus which to be used in a vertical position is
provided with a plunger tube T (see Figure 1) which extends to the bottom of the
reservoir.
This arrangement is necessary, in order that the liquid only may escape from the
apparatus and not the gas. This tube T is dispensed with in the apparatus to be
used in an inclined position. But in order to have the apparatuses capable of
serving at the same time for the vertical and for the inclined position I have placed
a cock at each extremity and by this means the apparatus is rendered more
practical in use for the two positions by an inappreciable movement of the hand of
the operator. This arrangement is shown at Figure 3.
To use the apparatus after having removed the stopper S, the cock C is opened
by turning the key F and the apparatus is turned towards the part to be benumbed,
the button J of the rod J is pressed during the necessary time. The liquid finds
a passage by the orifice ; of the rod J and arrives in the nozzle P and on account
of the pressure which is in the reservoir A of at least four atmospheres it traverses
the spray producer R and benumbs the part to be operated upon.
The apparatus is completed by a plate U which is screwed upon the bottom and

page_text: which is provided with rubber cork or other soft material to enable the operator to
hold the apparatus in his mouth so as to leave both hands free for operating. In
order to enable the apparatus to be applied to any part of the body I can replace
the nozzle or mouthpiece P by nozzles of other suitable forms as shown in
Figures 8. 9. 10.
Figure 11. is a spray producing connection.
Figure 12 shows a movable piece which may have any suitable form and which
serves to connect the apparatus to the different nozzles employed according to the
parts of the body upon which it is desired to operate.
It will be understood that I do not limit myself to the forms shown for the
nozzles, cocks, connecting pieces and movable rods as they are only given as
examples.
I reserve the right to manufacture my apparatus of any size, as well as the
accessories such as the valves, nozzles spray producing connections &c. &c.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. In a spray producing apparatus employed for applying anesthetics, the
combination of a reservoir and of a cock fixed at its upper end having two passages
one for the use of the apparatus, formed by a screw threaded rod forming a valve,
the other provided with a screw threaded stopper and which serves to allow the air
contained in the apparatus to escape during the filling operation substantially as
herein shown and described.
2. The combination with the cock referred to in Claim 1. of a rod with a
transverse hole placed at its inner end provided with a button upon which pressure
is applied in order to bring the hole in the rod in a line with that leading from the
cock when it is desired to use the apparatus substantially as herein shown and
described.
3. In order to prevent the transversely perforated rod from turning and to
prevent the spring from acting during the filling operation the employment of two
pins sliding in one groove made in the cock and of a dise or washer formed with a
groove or recess, one of the pins acting as a guide the other as a stop to keep
the apparatus open when the disc or washer is turned which no longer presents
its groove or recess before the second pin substantially as herein shown and
described.
4. The employment, instead of the rod and of the disc or washer hereinbefore
claimed and mounted in the power closing cock of a second valve cock screwed
upon this latter and capable of being removed, the said valve being worked from
the exterior by pressing upon a button mounted at the end of its rod and arranged
in such a way that the pressure of the liquid contained in the apparatus is added to
that of the spring in order to secure a tight joint substantially as herein shown and
described.
5. The substitution of the valves hereinbefore claimed by those shown in
Figures 5, 6 and 7 substantially as berein shown and described.
6. The employment of suitably shaped nozzles adapted to the various parts of
the body to be operated upon such as those shown in Figures 8, 9 and 10 or of
other form.
7. The employment of spray diffusing connecting pieces substantially as herein
sbown and described.
8. The employment of movable connecting pieces for use with the different
nozzles substantially as herein shown and described.
9. The arrangement and combination of a double apparatus that is to say having
a valve cock at each end as shown in Figure 3. enabling a single apparatus to be
used in either a vertical or inclined position substantially as herein shown and
described.
