PROVISIONAL SPECIFICATION.
An Improved Instrument and Liquid for Blowing Bubbles.
I, CHARLES ALFRED BOOTH, of 3, St. George's Place, Brighton, Accountant,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved instrument for blowing bubbles and to a
liquid composition to be employed for that purpose.
The improvement in the bubble-blowing instrument has for its object to enable
the liquid composition to be contained in an attached receptacle so that it may be
thence continuously supplied to the bowl of the instrument in just the quantity
required, so as to avoid the necessity for carrying a separate vessel for the liquid
and prevent waste by too copious a supply, as happens when the bowl is dipped
into the liquid.
'
For this purpose I combine with the blowing instrument, which may be in
the form of an ordinary tobacco pipe, an elastic bulb to contain the supply of
liquid, this bulb being detachably connected to the blow-pipe so as to enable the
bulb to be readily re-filled from a phial. The bulb is mounted on, or otherwise
attached to, the pipe and is connected to an orifice leading into the pipe bowl or
into the bore of the pipe stem at the point most suitable for the injection into the
current of air of the small quantity of liquid required for the formation of the
bubbles, the injection being performed by slightly compressing the bulb from time
to time.
The improved liquid composition to be used for the above mentioned purpose
consists in the addition to soap and water of certain proportions of isinglass or
other gelatinous material and of glycerine whereby to impart greater tenacity and
permanency to the skin or enveloping film of the bubble as well as to enhance the
variegated iridescent effects produced by the play of light upon the surface. To
the above mentioned ingredients, colouring matter may be added in order to
produce bubbles of different tints.

An Improved Instrument and Liquid for Blowing Bubbles.
I, Charles ALFRED BOOTH, of 3, St. George's Place, Brighton, Accountant,
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 relates to an improved instrument for blowing bubbles and to a
liquid composition to be employed for that purpose.
The improvement in the bubble-blowing instrument has for its object to enable
a liquid composition to be contained in an attached receptacle and to be thence.
continuously supplied to the bowl of the instrument in just the quantity required
[Price 8d.l

page_text: to form a bubble so as to avoid on the one hand the use of a separate vessel for
the liquid and on the other hand to prevent spilling and waste of the liquid by too
copious a supply as happens when the bowl of the bubble-blowing pipe is charged
by dipping into the liquid.
In order that the invention may be more readily understood, I have illustrated
it in the accompanying drawings, forming part of this Specification, wherein
Figure 1 represents an external view of the instrument complete, and Figure 2
is a longitudinal section thereof, shewing the form of the bore and bowl.
Figures 3 and 4 shew details.
The same letters of reference denote like parts in all the figures.
For the purpose of my invention I combine with the blowing instrument proper,
which is represented by the letter A and which may be similar in external form to
an ordinary tobacco-pipe, an elastic bulb B to contain the supply of liquid, this
bulb being detachably connected to the blow pipe so as to enable the bulb to be
readily refilled from a phial. The blowing instrument or pipe A may be made of
any suitable material, but is preferably of clay and formed by moulding in the
manner commonly practised for clay-pipes. Instead of being made with a
'capacious bowl, as in the case of a tobacco-pipe, the bowl a although it may
present externally the form of a tobacco-pipe, is practically solid, there being only
a shallow concavity or depression a', the surface of which is glazed and preferably
corresponds in form to a segment of a sphere the better to maintain the bubble
whilst undergoing dilatation and likewise to permit the easy severance of the fully-
developed bubble from the instrument without causing the bubble to burst. Into
this cavity leads a central bore 6 which branches from a bore c extending, as
shewn in Figure 2, transversely across the body part in the fore and aft direction
corresponding to that of the stem. The bore c is connected at one end by a
'channel with the bore e of the stem, the bores b, c, and e being bored or moulded
in the pipe in the usual way of pipe-making whilst the channel d is, for
'convenience of manufacture, made in the form of a groove in a separately
moulded piece D (Figure 3) which fits into a corresponding countersunk
cavity (Figure 4) provided for its reception in the back of the bowl, the cavity
being moulded or otherwise formed in the body part and the piece D being secured
therein in any suitable way such as by cementing or gluing, according as a clay or
wood bowl is used. The other end of the transverse bore c is flared to receive
the tapered end of the nozzle part B', of the bulb B. The latter made of
vulcanized rubber and the tubular nozzle B', may either be moulded with it or be
(a separate piece of any suitable hard material, the neck of the bulb being bound
to it by a ligature of wire. The bulb B is mounted in position by the nozzle being
supported in a standard E fixed in any suitable manner on the pipe stem and by
the end of the nozzle, being fitted into the orifice of the bore C, from which, in
Figure 2, it is shown withdrawn.
.
The instrument is held as illustrated in Figure 1 and by applying slight pressure
to the base of the bulb, the small quantity of liquid required to form a bubble
may be injected into the bore c where it meets the current of air blown through
the stem and the channel d at the point where the axial bore 6 springs, that is the
point most suitable for the formation of a bubble from the minimum quantity of
liquid.
The standard E may be a slip of wood or other soft material apertured to fit
tightly upon the tapered stem of the pipe.
The improved liquid composition to be used for the above mentioned purpose,
consists in the addition to soap and water of certain proportions of isinglass or
other gelatinous material and of glycerine whereby to impart greater tenacity and
permanency to the skin or enveloping film of the bubble as well as to enhance
the variegated iridescent effects produced by the play of light upon the surface.
The preferred recipe for making it is as follows :-Dissolve half an ounce of best
Castile or pure soft soap in half a pint of rain water; add two drachms of
glycerine and a small quantity of gum arabic or Japanese isinglass.

page_text: 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. The herein described instrument for bubble blowing, consisting in 'the
combination, with a blow-pipe, substantially as described, of an elastic bulb
mounted on the pipe and connected with the bore thereof, substantially as.
specified.
2. The herein described liquid composition for bubble blowing, as specified.
