Improvements in Machines or Apparatus for Spraying Liquids,
chiefly Designed for Moistening Tobacco.
1, PIERRE LORILLARD Junior, of Tuxedo Park, Orange County, New York,
United States of America, 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:-
My improvement relates more particularly to machines for distributing liquid in
minute particles upon tobacco, but it is applicable to the distribution of liquids in a
similar manner for various other purposes, and also to mixing one liquid with
another.
I will describe a machine embodying my improvement, and then point out the
novel features in a claim.
In the arcompanying drawing, Figure 1 is a partly sectional top view of a
machine embodying my improvement. Figure 2 is a vertical section of the same.
Similar letters of reference designate corresponding parts in both figures.
A designates a tank containing liquid. As here shown, it is of rectangular
form, and supported by lugs a.
B designates a screen of foraminous or reticulated material, supported within
the said tank. As here shown, it is made in the form of a drum at whose ends are
heads provided with journals that are mounted in bearings supported by sides
of the tank. It is intended that this shall rotate within the tank and pick up and
carry liquid from the same, to a certain position, whence it shall be discharged.
I do not wish, however, to be limited to the special form of screen shown, as my
invention is broad enough to cover a movable screen of other shapes.
To impart motion to the rotary screen which I have illustrated, one of its journals
is provided with a worm-wheel 63 that engages with a worm C, the latter being
mounted upon a shaft C', which is journaled in bearings affixed to one side of the
tank. This shaft is provided with a cone pulley c. Opposite this cone pulley is
a reverse cone pulley d, affixed to a shaft which is mounted in bearings in standards
erected upon the floor. A belt E passing around the cone pulleys, may be adjusted
by a belt shifter F, to different positions, for the purpose of varying the speed of
the screen.
G designates a discharge nozzle which is supported behind or within the screen.
As shown, it is made to taper from a point opposite the journals of the screen to
an edge which extends in close proximity to the periphery of the screen and
substantially the whole axial length of the screen. At one end of the larger
portion of this nozzle, is connected a pipe H, leading from a rotary blower I, the
latter being driven by means of a belt J which can be shifted whenever necessary,.
upon an idler pulley i.
As the screen slowly moves, it picks up liquid from the tank, and carries it to a
point opposite the discharge nozzle, whereupon air which is forced from the same,
blows off the liquid in the finely divided particles in which it is held by the screen.
The material which will receive the liquid being properly located, more or less
distant from the screen, will have it properly distributed upon it, or in it, if it be
another liquid.

page_text: Instead of forcing air through the discharge nozzle, any other fluid, as, for
instance, a liquid, may be forced through it. When liquid is forced through it, a
suitable pump will be employed instead of the blower.
It will also be apparent that instead of the nozzle shown, any device may be
employed for directing the discharge fluid against the reticulated or foraminous
screen, as, for instance an orifice of any desired shape.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of a foraminous or reticulated screen, means for supplying
the screen with particles of liquid, a discharge device on one side of the screen,
and means for forcing fluid through the discharge device and the screen to project
the liquid carried by the latter in a finely divided state, substantially as
specified.
2. The combination of a tank containing liquid, a movable foraminous or
reticulated screen dipping into said tank, and adapted to elevate particles of
liquid therefrom, a discharge device on one side of the screen, and means for forcing
fluid through the discharge device and the screen to project the liquid carried by
the latter in a finely divided state, substantially as specified.
3. The combination of a tank containing liquid, a foraminous or reticulated screen
movable therein and arranged to elevate particles of liquid from the tank, and
means for forcing said particles of liquid from the screen in a finely divided state,
substantially as specified.
4. The combination of a tank containing liquid, a cylindrical foraminous or
reticulated screen dipping therein and adapted to elevate particles of liquid from
the tank, a discharge device mounted centrally within the screen and having its
point of discharge at or near the periphery of the screen, and means for rotating
the latter, substantially as specified.
