IMPROVEMENTS IN APPARATUS FOR CONVERTING LIQUID INTO SPRAY."
Year: 1882

page_text: LETTERS PATENT to Lawrence Hill Armour of 16 West Street Gateshead
Civil Engineer, for an invention of "IMPROVEMENTS IN APPARATUS FOR
CONVERTING LIQUID INTO SPRAY."
PROVISIONAL SPECIFICATION left by the said Lawrence Hill Armour at the
Office of the Commissioners of Patents on the 25th April 1882.
LAWRENCE HILL ARMOUR of 16 West Street, Gateshead, Civil Engineer.
"IMPROVEMENTS IN APPARATUS FOR CONVERTING LIQUID INTO SPRAY."
My Invention consists in the application of a rapidly rotating disc or disca so as
to break up and convert into spray or minute particles any suitable liquid which
may be applied to them and whether singly to one disc or in succession to a series
of two or more discs.--If one disc be employed I mount it on a spindle to which is
attached a pulley or other device for producing very rapid rotation and when put
in action I cause the liquid which is to be converted into spray to be supplied to
the disc in regulated quantity, and the effect of this is to produce a more or less
fine spray-When the spray is required for the saturation of the liquid so employed
by some gas or vapours, I pass the liquid several times over the disc collecting it
at each diffusion in a vessel by which the disc is surrounded and through which
the gas is passing, or I employ two or more discs on the same spindle, the liquid
diffused from the first being collected in a channel or groove in the surrounding
vessel and led by a pipe to the second disc and so on.-I select the material for the
discs and surrounding vessel in relation to the liquid or gas to be operated upon
and I also corrugate slightly or roughen the surfaces of the disc so as to produce a
more or less fino spray as may be required. 1 employ this invention for the
extraction of fumes of hydrocloric acid in Alkali Works, Lead fumes in Lead Works,
or for the purification of coal gas or for other like purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Lawrence Hill Armour in the Great Seal Patent Office on the
23rd October 1882.

IMPROVEMENTS IN THE PRODUCTION OF SPRAY.
My invention consists in the application of a rapidly rotating disc or discs so as
to break up and convert into spray or minute particles any suitable liquid which

page_text: may be applied to them and whether singly to one disc or in succession to a series
of two or more discs.-If one disce be employed I mount it on a spindle to which is
attached a pulley or other device for producing very rapid rotation and when put
in action I cause the liquid which is to be converted into spray to be supplied to
the disc in regulated quantity and the effect of this is to produce a more or less
fine spray-When the spray is required for the saturation of the liquid so employed
by some gas or vapour I pass the liquid several times over the disc collecting it at
each diffusion in a vessel by which the disc is surrounded and through which the
gas is passing or I employ two or more discs on the same spindle the liquid diffused
froin the first being collected in a channel or groove in the surrounding vessel and
led by a pipe to the second disc and so on.-I select the material for the discs and
surrounding vessel in relation to the liquid or gas to be operated upon and I also
corrugate slightly or roughen the surface of the disc so as to produce a more or less
fine spray as may be required.-I employ this invention for the extraction of fumes
of hydrocloric acid in Alkali Works, lead fumes in Lead Works, or for the
purification of coal gas or for other like purpose.
Having thus described the nature of my invention I will proceed more
particularly to describe the manner in which it is operated reference being had to
the drawing hereto attached.-The drawing represents a vertical section of an
apparatus with four-discs-but-one or any larger number may be employed.-The
four discs lettered A. are mounted and-keyed on a central spindle B. which-passes-
through the cylindrical vessel X. by a stuffing box, C. to a pulley D, also attached
to it and having a belt thereon capable of imparting to it very rapid rotation.-The
lower part is secured in the footstep E.-F. F. F. represent 3 diaphragms one under
_each_of_the 'upper discs fitted to the cylinder in which the whole is contained so
as to be water and air tight or nearly-so; G-and H. are respectively the ingross
and egress pipes of the gas to be condensed or washed and I. and J. respectively
the ingress and egress pipes of the liquid to be converted into spray.-G. 1. repre-
sents openings-with-raised-lips.as shewn to allow of the passage of the gas upwards
and I. 1. represents openings ending in pipes through which the-liquid-collected
from one disc upon the diaphragm below it is caused to flow into a disc beneath.-
By this arrangement a supply of liquid in its passage from I. to J. is four times
converted into spray and gas passing from G. to H. is four times in succession
subjected to its influence.
Having thus described the nature of my invention and the manner of operating
the same I claim the use of a disc or discs revolving at a high speed for the
production of spray substantially as described.
In Witness whereof I the said Lawrence Hill Armour have hereunto set
my hand and seal this nineteenth day of October in the year of our
Lord one thousand eight hundred and eighty two.
Witness to the Signature of
Lawrence Hill Armour.
