page_text: I, JOHN GEORGE FRANKLIN, of 11 Hoxton Street, Shoreditch, in the County of
Middlesex, Surgical Instrument Manufacturer do hereby declare the nature of this
invention to be as follows:-
The objects of my invention are to make apparatus for producing spray, which
are simple in construction, effective in action, and self contained, all as hereafter
described.
According to my invention the spray producer is composed of a compound vessel
or vessels divided centrally and made of india rubber or suitable flexible material,
having a valve between the two; one vessel forms a hand bellows, the other an air
chamber. This air chamber contains the bottle for holding the liquid to be sprayed,
and I prefer to make this bottle of vulcanite or of some other non-breakable
material, the neck of the bottle is clipped and held by the neck of the air chamber
and through the said neck a tube which may be made of any suitable material
passes to near the bottom of the bottle at one end, and having a bent or other
suitable shaped nozzle at the other end, with cap to prevent the escape of liquid
when the apparatus is not in use. There is a tube from the air chamber to the
nozzle outside the neck. The hand-bellows has a valve at the base which closes
when the bellows is compressed, and admits air as it expands.
To use the spray producer, disconnect the nozzle of the tube, and place the liquid
to be sprayed in the internal receptacle. The nozzle is then re-connected; the
short tube, preferably formed of india rubber, leading from the air chamber is
slipped over an arm provided on the spray tube, and, connection thus being made,
the apparatus is ready for use. To diffuse the spray compress the portion of the
india rubber vessel forming the hand-bellows, whereby air will be forced through
valve into that portion forming the air chamber, the pressure driving same out
through the tube leading from air chamber into the nozzle.
The current of air passing through the upper part of spray tube causes a
vacuum in the lower part of tube, and the liquid in the receptacle is thereby drawn
up, and is ejected in the form of spray. The hand-bellows is then allowed to
expand, and expanding draws in air through the valve aforesaid, and is again
ready for compression; the operation being continued as desired. By alternately
compressing and releasing the hand-bellows a continuous spray jet is obtained.

page_text: When not in use, the cap provided is placed upon the point of "spray" and
effectively prevents the escape of any liquid, and also the admission of any grit
or dirt.
Apparatus for producing spray, constructed in accordance with this invention are
extremely simple of adjustment for use, and are portable, being easily carried in the
pocket without requiring a case. Further advantages are that, the air chamber and
hand-bellows being continuous, there is less likelihood of breaking than with those
heretofore made; the receptacle for containing the liquid being attached as
described, only one hand is required to operate the apparatus; and the air chamber
being of non resisting material affords equal and sufficient pressure for the production
of the spray, and no outside covering of net is required.

page_text: I, JOHN GEORGE FRANKLIN of 11 Hoxton Street, Shoreditch, in the County of
Middlesex, Surgical Instrument Manufacturer 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:-
The objects of my invention are to make apparatus for producing spray, which
are simple in construction, effective in action, and self contained, all as hereafter
described.
Figure 1 of the accompanying drawings is a general view; Figure 2 is a
longitudinal vertical section, and Figure 3 is a plan, of the apparatus for producing
spray, Constructed according to my invention,
The spray producer is composed of a compound vessel or vessels A and B made
of india rubber or other suitable flexible material, divided centrally by a diaphragm C
having a valve D between the two compartments; one vessel A forming a hand
bellows, the other vessel B an air chamber. This air chamber B contains the
bottle E for holding the liquid to be sprayed, and I prefer to make this bottle of
vulcanite or of some other non-breakable material; the neck of the bottle is clipped
and held by the neck of the air chamber B, and through the said neck a tube F
which may be made of any suitable material, passes to near the bottom of the
bottle E at one end, and having a bent or other suitable shaped nozzle G, at the
other end with cap H to prevent the escape of liquid when the apparatus is not in
use. There is a tube I from the air chamber to the nozzle outside the neck. The
hand bellows A has a valve K at the base which closes when the bellows A. is
compressed, and admits air as it expands.
To use the spray producer, disconnect the nozzle G of the tube F and place the
liquid to be sprayed in the internal receptacle E. The nozzle is then re-connected,
the short tube I preferably formed of india rubber leading from the air chamber B
is slipped over an arm L provided on the spray tube G, and connection thus being
made, the apparatus is ready for use. To diffuse the spray compress the portion of
the india rubber vessel A forming the hand bellows, whereby air will be forced
through valve D into that portion B forming the air chamber, the pressure driving
same out through the tube I leading from air chamber into the nozzle G.
The current of air passing through the upper part of spray tube G causes a
vacuum in the lower part of tube F, and the liquid in the receptacle E is thereby
drawn up, and is ejected in the form of spray. The hand bellows A is then allowed
to expand, and expanding draws in air through the valve aforesaid, and is again
ready for compression, the operation being continued as desired. By alternately
compressing and releasing the hand bellows A, a continuous spray jet is obtained so
long as any liquid remains in the receptacle E.
When the apparatus is not in use the cap H provided for that purpose is placed
upon the point of "spray" and effectively prevents the escape of any liquid, and
also the admission of any grit or dirt.
Apparatus for producing spray constructed in accordance with this invention are
extremely simple of adjustment for use and are portable, being easily carried in the

page_text: pocket without requiring a case. Further advantages are, that the air chamber and
hand bellows being continuous there is less likelihood of breaking than with those
heretofore made; the receptacle for containing the liquid being attached as described,
only one hand is required to operate the apparatus, and the air chamber being of
non-resisting material affords equal and sufficient pressure for the production of the
spray, and no outside covering of net is required.
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:
In spray producers or diffusers, the combined bellows and air chamber having
receptacle for the liquid to be sprayed, contained in the air chamber itself, together
with the means described for producing the spray, all being self contained and
capable of being carried in the pocket and when used to be operated by one hand
all substantially as herein before described, and illustrated with reference to the
accompanying drawings.
