page_text: 'T, HEINRICII HELBING of 63 Queen Victoria Street in the City of London;
Chemist, do hereby declare the nature of this invention to be as follows::-
This invention relates to the preparation and application of menthol; and con-
sists essentially in the combination of menthol with chloride of methyl or chloride
of ethyl, or a mixture thereof, and with or without alcohol; and in its application
in the form of a spray.
In the Specification of Patent 16392 of 1890 is described a receiver for the
preservation and application of chloride of ethyl by means of a glass flask, in
which is sealed the necessary amount of chloride of ethyl; and which latter on
the seal being broken is ejected in the form of spray on account of the internal
pressure existing or caused by the warmth of the hand on the flask. This device
was very useful in minor, surgical operations in order to cause local anesthesia:
Menthol has been used for local application in cases of neuralgia or kindred
nervous disorders in the form of cones or sticks mixed with wax, or dissolved in
oils.
According to this invention I dissolve menthol in chloride of ethyl or of methyl,
or in a mixture of both, and I may add thereto methyl or ethyl alcohol:
.
I place the solution in a receiver of glass or metal provided with a smäll orifice
which can be hermetically closed by means of a tightly fitting cap. On this cap
being removed, and the receiver inclined, the solution of menthol and ethyl
chloride or methyl chloride will be ejected in a fine jet or spray by reason of the
internal pressure created by the evaporation of the liquid, which is, caused by
the warmth of the hand.or even of the atmosphere of the room. This, jet or.spray
can be directed on to the required part, and since the dissolving material rapidly
evaporates, not merely is the menthol evenly distributed over the required surface,
but the anaesthetic action of the chloride of ethyl or methyl tends to increase the
effect of the menthol and gives relief to the patient.
Hitherto menthol has been applied by rubbing, but by means of this invention
menthol can be applied without rubbing and in the form of spray to damaged
nerve tracts, and this treatment of nervous affections will be greatly facilitated
in cases where nerves are required to be soothed and strengthened by external
application.

page_text: I, HEINRICH HELBING of 63 Queen Victoria Street in the City of London,
Chemist, 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 relates to the preparation and application of menthol, and con-
sists essentially in the combination of menthol with chloride of methyl or chloride
of ethyl or a mixture thereof, and 'with or without alcohol, and its application
in the form of a spray.
In the Specification of Patent 16392 of 1890 is described a receiver for the
preservation and application of chloride of ethyl by means of a glass flask, in
which is sealed the necessary amount of chloride of ethyl, and which latter on
the seal being broken is ejected in the form of spray on account of the internal
pressure existing or caused by the warmth of the hand on the flask. This device
was very useful in minor surgical operations in order to cause local anesthesia.
Menthol has been used for local application in cases of neuralgia or kindred
nervous disorders-in-the form of cones or sticks mixed with wax or dissolved in
oils.
According to this invention I dissolve menthol in chloride of ethyl or of methyl,
or in a mixture of both, and I may add thereto methyl or ethyl alcohol, taking
for example 1 part menthol, 1 part alcohol and 18 parts ethyl chloride.
I place the solution in a receiver of glass or metal provided with a small orifice
which can be hermetically closed by means of a tightly fitting cap. On this cap
being removed, and the receiver inclined, the solution of menthol and ethyl
chloride or methyl chloride will be ejected in a fine jet or spray by reason of the
internal pressure created by the evaporation of the liquid, which is caused by
the warmth of the hand or even of the atmosphere of the room. This jet or spray
can be directed on to the required part, and since the dissolving material rapidly
evaporates, not merely is the menthol evenly distributed over the required surface,
but the anesthetic action of the chloride of ethyl or methyl tends to increase the
effect of the menthol and gives relief to the patient.
Hitherto menthol has been applied by rubbing, but by means of this invention
menthol can be applied without rubbing and in the form of spray to damaged
nerve tracts, and this treatment of nervous affections will be greatly facilitated
in cases where nerves are required to be soothed and strengthened by external
application.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
The combination of menthol with chloride of ethyl or methyl with or without
the addition of alcohol substantially as and for the purposes described.
