IMPROVEMENTS IN APPARATUS FOR DISTRIBUTING LIQUID IN THE FORM OF SPRAY
Year: 1881

page_text: LETTERS PATENT to William Wells, of Earlswood, in the County of Surrey,
for an Invention of "IMPROVEMENTS IN APPARATUS FOR DISTRIBUTING
LIQUID IN THE FORM OF SPRAY."
PROVISIONAL SPECIFICATION left by the said William Wells at the Office
of the Commissioners of Patents on the 9th April 1881.
"IMPROVEMENTS IN
WILLIAM WELLS, of Earlswood, in the County of Surrey.
APPARATUS FOR DISTRIBUTING LIQUID IN THE FORM OF SPRAY."
My Invention relates to an improved spray diffuser intended more particularly
for horticultural and garden purposes, for distributing liquids inimical to insect life,
but it is also applicable for disinfecting, cooling, and perfuming purposes generally.
The apparatus consists of a pair of lever handles jointed together at one end and
worked in the manner of a pair of bellows. The one handle is bowed or otherwise
adapted to receive and hold the usual elastic bulb by which the atomizing blast is
ejected through a tube leading along the said arm, and terminating in a nozzle at
the end thereof. The other handle is similarly bowed or adapted to hold a glass
bulb containing the liquid to be atomized, said bulb also serving to compress the
elastic bulb when the two handles are pressed together; or instead of a glass bulb.
an ordinary bottle, preferably one of earthenware, such as are in common use, may
be used, the handle being provided with a socket or otherwise adapted to press on
the elastic bulb, and to receive and hold the bottle which is held in place by
suitable straps or other fastenings, and can thus be readily replaced in case of
breakage. If a bulb be used it would be partly embraced by a bow on the handle
and secured removably therein by a strap. A flexible tube passes through the
stopper of said bulb or bottle, and leads to an annular passage within the nozzle
surrounding the orifice of the air tube, whereby on pressing the handles together
a jet of air is ejected, and part of the liquid contained in the bulb or bottle is
exhausted and ejected through the nozzle in the form of spray.

an Order of the Lord Chancellor, filed by the said William Wells in the Great
Seal Patent Office on the 14th October 1881.
"IMPROVEMENTS IN
WILLIAM WELLS, of Earlswood, in the County of Surrey.
APPARATUS FOR DISTRIBUTING LIQUID IN THE FORM OF SPRAY."
My Invention relates to an improved spray-diffuser intended more particularly
for horticultural and garden purposes, for distributing liquids inimical to insect
life. It is however also applicable for disinfecting, cooling, and perfuming purposes
generally.
And in order that my said Invention may be better understood and readily
carried into effect, I will now with the aid of the accompanying Drawings, wherein
similar numbers and letters of reference indicate corresponding parts, proceed more
particularly to describe and ascertain the same.
Figure 1 shews a view of my improved spray diffusing apparatus complete ;
and Figure 2 shews a view of the lever arm (2) with the arrangement of the glass
bulb and socket.
My improved apparatus consists of a pair of lever arms (1,2,) fitted with
handles (a), and hinged together at their upper ends in such a manner that they
work like a pair of bellows.
The lever arm (1) is bowed and fitted with a cup shaped socket (3) to receive
and hold an elastic air bulb (4), by means of which the atomizing blast is ejected
through an elastic tube (5) leading along the said lever arm (1), and terminating
in a nozzle (6) at the end thereof provided with a metal cap (7) which screws on
and off. The lever arm (2) is also bowed and fitted with a cup shaped metal
case (8) or its equivalent, adapted to receive and hold a glass bulb (9) containing
the liquid to be diffused. Such case is fitted with a cover (10) in order to afford
protection to the glass bulb, and when the two handles are pressed together such
metal case and bulb serve to compress the elastic bulb (4), and produce a jet of air
as presently described. Or instead of such glass bulb an ordinary bottle, preferably
of earthenware, such as those in common use may be employed, the lever arm (2)
being provided with a socket or otherwise adapted to press on the elastic bulb, in
the manner already described, and to receive and hold the bottle which may be
held in place by suitable straps or other fastenings, and can thus be readily
replaced in case of breakage. If a bulb be used it should be partly embraced and
protected by a bow on the lever arm (2), and secured therein by a strap or other-
wise so as to be readily removable. Such glass bulb or bottle is filled with any
kind of liquid, either insecticide, disinfectant, cooling, perfumed, or otherwise, as
required, and of any desired strength. It is provided with a stopper or plug (11)
through which a flexible tube (12) passes, and leads to an annular passage (13)
formed in the nozzle surrounding the orifice of the air tube, whereby on sharply
pressing the handles together a jet of air is ejected from the elastic bulb (4) up the
tube (5) which draws or syphons the liquid contained in the glass bulb or bottle (9)
up the flexible tube (12), and ejects it through the nozzle (6) in the form of spray.
The fineness or coarseness of the spray so diffused is regulated according to the
pitch to which the metal cap (7) is adjusted.
Having thus described the nature of my said Invention, and the manner of
carrying the same into effect, I would have it understood that what I claim as
novel and as of my Invention is the improved construction of apparatus for
diffusing liquid in the form of spray consisting of hinged lever arms (1, 2,) with
handles (a), cup shaped socket (3), elastic air bulb, and blast tube (4, 5,) nozzle (6)
with annular passage (13), metal cap (7), metal case (8) or its equivalent, with

page_text: glass bulb or bottle (9), stopper or plug (11), and syphon tube (12), all combined,
arranged, and fitted substantially in the manner and for the purposes herein before
described and illustrated.
In witness whereof, I, the said William Wells, have hereunto set my hand
and seal, this Eleventh day of October, in the year of our Lord One
thousand eight hundred and eighty one.
Witness,
WILLIAM WELLS. (L.S.)
