We, GEORGE EDWARD HOLLOWAY, General Manager, and a Corporate Body
trading as B. DELLAGANA AND COMPANY, LIMITED, Electrotypers, all of 1, Gresham
Buildings, Basinghall Street, London, EC., do hereby declare the nature of this
invention to be as follows:-
This invention relates to spraying apparatus adapted in very simple form to
spray liquid in a more or less finely divided condition, which is thus particularly
adapted for the spraying of liquid colours for the decoration of pottery or other
ceramic and enamel ware.
This apparatus consists essentially of a closed chamber of tin, copper or other
suitable material thus adapted to float, and to float at any desired depth accord-
ing to the removal of, or addition to, a superincumbent weight, upon any liquid,
such as liquid colour.
The interior of the floating chamber is connected, conveniently, by an elastic
tube, to any source of compressed air or gas, such as an air compressor, or a gas
storage bottle, and the air or gas is allowed to issue upwards through a nozzle or
nozzles, of which there may be any desired numbers distributed over the upper
surface of the floating chamber.
Through the under face of the floating chamber, a liquid suction tube is placed
under each of the upper air or gas nozzles, such suction tubes being sufficiently
low to be below the surface of the liquid upon which the air chamber floats and
so as to enter into the air or gas nozzles for some distance.
The escaping air or gas thus sucks up the liquid upon which the air chamber
floats and transforms it into a continuous spray, rising to a proportionate height
with the pressure of air or gas applied.
Fixed at a convenient distance above the mouth of each nozzle is a concave
spreader which diffuses the spray and facilitates the coating of any surface placed
above or before it, with an even distribution of the liquid.
Any degree of fineness of such spray may be regulated by the pressure of the
air or gas used for ejection, and by the level at which the floating chamber is
weighted to float and the distance of the suction tube from the mouth of air
or gas nozzle and the whole apparatus is exceedingly simple and cheap.

We, GEORGE EDWARD HOLLOWAY, General Manager, and a Corporate Body
trading as B. DELLAGANA AND COMPANY, LIMITED, Electrotypers, all of 1, Gresham
Buildings, Basinghall Street, London, E.C., 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 spraying apparatus adapted in very simple form to
spray liquid in a more or less finely divided condition, which is thus particularly
adapted for the spraying of liquid colours slip, glaze, or enamels, for the decora
tion of pottery or other ceramic, and enamel ware.
This apparatus consists essentially of a closed chamber of tin, copper or other
suitable material, thus adapted to float, and to float at any desirable depth accord-
ing to the removal of, or addition to, a superincumbent weight, upon any liquid,
such as liquid colour.
The interior of the floating chamber is connected, conveniently by an elastic
tube, to any source of compressed air or gas, such as an air compressor, or a gas
storage bottle, and the air or gas is allowed to issue upwards through a nozzle or
nozzles, of which there may be any desired numbers, distributed over the upper
surface of the floating chamber.
Through the under face of the floating chamber, a liquid suction tube is placed
under each of the upper air or gas nozzles, such suction tubes being sufficiently
low to be below the surface of the liquid upon which the air chamber floats, and
so as to enter into the air or gas nozzles for some distance.
The escaping air or gas thus sucks up the liquid upon which the air chamber
floats and transforms it into a continuous spray, rising to a proportionate hright
with the pressure of air or gas applied.
Fixed at a convenient distance above the mouth of each nozzle is a concave
spreader which diffuses the spray and facilitates the coating of any surface, placed
above or before it, with an even distribution of the liquid.
Any degree of fineness of such spray may be regulated by the pressure of the
air or gas used for ejection and by the level at which the floating chamber is
weighted to float, and the distance of the suction tube from the mouth of the air
or gas nozzle, and the whole apparatus is exceedingly simple and cheap.
And in order that this invention may be the better understood we will now pro-
ceed to describe a practical example of our apparatus, reference being had to the
drawings hereto annexed, and to the letters and figures marked thereon.
Fig. 1 is a general plan of our apparatus and
Fig. 2 is a transverse section through the same.
AA are two detached floats of hollow metal having bearers B B holding the
said floats and affording a platform on which to place the hollow ejector box C.
It is evident however that, if desired, the box C itself can be of sufficient dis-
placement to float itself, without added floats. The arrangement as shown however
is most convenient.
Dis the india rubber or flexible supply-tube for the compressed air or gas, ob-
tained from an air compressor or from a storage gas bottle.
On the upper face of the box C are fitted any desired number of nozzles E in
the centre of each of which is a suction tube F. which passes through the bottom
of the box into the supporting liquid, such as liquid paint.
The escaping air or gas through the nozzles E thus sucks up the liquid paint
through the tube F. and transforms it into a continuous spray suitable for colour.

paint is desired a spreader G may be fixed at a convenient distance above any or
all of the nozzles.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed we declare that what we
claim is:-
1st. An apparatus for spraying liquid such as colour, slip, glaze, or enamel,
consisting of a closed chamber or box adapted to float at a desired height or depth
upon the said liquid, receiving an internal supply of compressed gas or air; and
having on its upper sffrface a series of nozzles, with or without spreaders, and in-
ternal suction pipes therein, passing through the bottom of the chamber to any
desired depth into the said liquid, substantially as and for the purposes described.
2nd. The combination and disposition of parts forming an apparatus for the
spraying of liquid, such as colour, slip, glaze, or enamel, substantially as described
and illustrated in the drawings annexed hereto.
