Improvements in or relating to Spraying Devices for Liquids, Paints,
and for similar purposes.
(A communication from ERNST LIEBSCHER, of Georgendorf, Bohemia, in the
Empire of Austria-Hungary, Gentleman).
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be us
follows:-
:
The portable spraying device forming the subject of this invention, may be
used for various purposes, as, for instance, for spraying coal or applying a colour-
ing substance to wood or other surfaces, for sprinkling floors, for making
ornamental paintings, for damping the air of rooms, for sprinkling linen, flowers
or other articles, the device being suitable both for very fluid and thick liquids
and can be readily adjusted to give a more or less fine spray and to project it to a
greater or lesser distance. These are the main advantages of the new spraying
device over those hitherto used, the action of which is based on the use of com-
pressed air, and from which this device differs, its action depending on centrifugal
force. In the liquid reservoir there is arranged a brush rotatable from the out-
side, the bristles of which as the brush rotates, strike a spray and thus projecting
the liquid upon them at a given point and in a given direction. A slot in the
reservoir forms an outlet for the spray produced.
,
The reservoir is closed at the top down to the central vertical longitudinal plane
by an arched cover. On this top is mounted on hinges an arched cover or flap.
A flange at the front edge of the flap engages on the inner side with the front
wall of the reservoir so as to prevent the projection of the liquid through the
joint. The flap may be secured in position by lugs or extensions on the cover and
lugs on the front wall, a pin being passed through said lugs when they are in
line to hold them in engagement, or the connection may be in any other suitable
manner.
The spindle of the circular brush rotates in bearings in the lateral walls of the
reservoir. This spindle is preferably made of two pin screw-threaded at the ends
which are screwed into the hub of the brush, so as to enable the latter to be
readily replaced. To one of the pins is secured a crank handle. The joints of
the journals of the spindle in the bearings could be easily made air-tight by means
of stuffing boxes or the like, but owing to the small pressure of the liquid, and
more particularly with liquids of thick consistency, such packing of the joint is
not necessary. Besides the reservoir need not be filled to such an extent as to
bring its contents up to the level of the bearings.
The circular brush is of greater or smaller width in accordance with the quantity
of liquid to be projected at each revolution of the crank. The bristles need not
form a closed or compact cylinder, they may be arranged in separate bundles.
For many purposes a single series of bristles extending all round, will be found

sufficient. The word bristles" is here to be understood in its widest sense, they
need not be animal bristles, but may be wires, teeth fibres of piassava or the like,
arranged in bundles or singly. Of course the kind and arrangement of bristles
influences the quantity of liquid &c. taken up and the distance to which it is
projected.
.
A rod adjustable by means of screws in slots in the lateral walls of the reservoir,
open at the end, and capable of being removed altogether, carries a spring or
springs for acting on the bristles in order to spray the liquid adhering to them.
These springs project to a greater or lesser extent into the path of the ends of the
bristles according to the position of the rod. In this way the distance to which
liquid is projected, can be also regulated. The bristles striking the edge of the
springs and being thus bent back, spray forward again after passing them and
project the liquid which they carry. This liquid is projected through a slot
provided for the purpose in the flap or cover. One spring only may be used but a
second spring is found to increase and complete the action. Were only one spring
used a certain portion of the liquid would still adhere to the bristles, but in the
two spring construction said remaining portion is shaken off by the second spring.
To enable the liquid projected by the first spring arranged at the back to pass
through the spring arranged in the front, the latter is provided with a slot, the
width of which is at least equal to that of the back spring.
The liquid running down on the outside of the cover is caught by a trough and
returned to the reservoir through a slot. A handle is provided for holding the
device in the left hand, the crank being rotated by the right hand. A top handle
may be added for carrying the apparatus in a convenient manner.

I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The portable spraying device forming the subject of this invention, may be
used for various purposes, as, for instance, for spraying coal or applying a colour-
ing substance to wood or other surfaces, for sprinkling floors for mixing
ornamental paintings, for damping the air of rooms, for sprinkling linen, flowers
or other articles, the device being suitable both for very fluid and thick liquids
and can be readily adjusted to give a more or less fine spray and to project it to a
greater or lesser distance. These are the main advantages of the new spraying
device over those hitherto used, the action of which is based on the use of com-
prssed air, and from which this device differs, its action depending on centrifugal
force. In the liquid reservoir there is arranged a brush rotatable from the out-
side, the bristles of which as the brush rotates, strike a spray and thus project
the liquid upon them at a given point and in a given direction.
reservoir forms an outlet for the spray produced.

Figure 1 is a longitudinal view partly in section on the line 1-1 of Figure 2
of a convenient construction of apparatus with the cover removed and the bristles
omitted..
Figure 2 is a vertical cross-section on the line 2-2 of Figure 1.
Figures 3 and 4 are similar views of an alternative form of construction.
Referring first to Figures 1 and 2 the reservoir A is closed at the top up to the
central vertical plane by an arched cover a. On the top is mounted, on hinges a¹
an arched cover or flap A. A. flange a² at the front edge of the flap engages on
the inner side with the front wall of the reservoir (Fig. 2) so as to prevent the
projection of the liquid through the joint. The flap may be secured in position by
lugs or extensions a³ on the cover and lugs at on the front wall, a pin as being
passed through said lugs when they are in line to hold them in engagement, or
the connection may be in any other suitable manner.
The spindle B of the circular brush rotates in bearings b in the lateral walls
of the reservoir A. This spindle is preferably made of two pins screw threaded at
the ends which are screwed into the hub c of the brush, so as to enable the latter
to be readily replaced. To one of the pins is secured a crank handle B¹. The
joints of the journals of the spindle in the bearings could be easily made air-
tight by means of stuffing boxes or the like, but owing to the small pressure of
the liquid, and more particularly with liquids of thick consistency, such packing
of the joint is not necessary. Besides the reservoir need not be filled to such an
extent as to bring its contents up to the level of the bearings as shown in the
drawing.
The circular brush C is of greater or smaller width in accordance with the
quantity of liquid to be projected at each revolution of the crank. The bristles
need not form a closed or compact cylinder, they may be arranged in separate
bundles as shown in Figure 4. For many purposes a single series of bristles
extending all round, will be found sufficient. The word "bristles" is here to be
understood in its widest sense, they need not be animal bristles, but may be wires,
teeth, fibres of piassava or the like, arranged in bundles, or singly. Of course the
kind and arrangement of bristles influences the quantity of liquid etc., taken up
and the distance to which it is projected.
A rod I adjustable by means of screws in slots d in the lateral walls of the
reservoir (Fig. 1) open at the end (Fig. 2) and capable of being removed altogether
carries a spring or springs D1, D2 for acting on the bristles in order to spray the
liquid adhering to them. These springs project to a greater or lesser extent into
the path of the ends of bristles, according to the position of the rod D. In this
way the distance to which liquid is projected, can be also regulated.
The bristles striking the edge of the springs and being thus bent back, spring
forward again after passing them and project the liquid which they carry. This
liquid is projected in the direction of, say, the arrows (Figure 2) through a slot e
provided for the purpose in the flap or cover A¹. One spring only may be used,
but a second spring is found to increase and complete the action. According to
Figure 2 the spring 12 acts first. Were this (or D¹) the only spring present, a
certain portion of the liquid would still adhere to the bristles, but in the two
spring construction said remaining portion is shaken off by the second spring. To
enable the liquid projected by the first spring D2 arranged at the back, to pass
through the spring arranged in front, the latter is provided with a slot d, the
width of which is at least equal to that of the back spring.
The liquid running down on the outside of the cover A is caught by a trough F
and returned to the reservoir through a slot f. A handle G is provided for hold-
ing the device in the left hand, the crank being rotated by the right hand. A top
handle N may be added for carrying the apparatus in a convenient manner.
A.
modified construction is shown in Figures 3 and 4. The arched cover a A¹ is
replaced by a flat cover hinged at a¹ and secured by a catch 3. In this case. a
single spring D¹ is employed fastened by a bolt or bolts D³ and a nut or nuts Di

page_text: to the side of the receptacle. The spring D₁ being provided with a slot D to
allow of adjustment.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner
the same is to be performed, I declare that what I claim is :-
1. A spraying device comprising a brush arranged within but rotatable from
the outside of a reservoir a spring projecting into the path of the brush and acting
to shake the liquid off the bristles of the same and project it through a slot in the
reservoir substantially as described.
2. In a spraying device of the kind described the combination with a spring
such as 11, of a spring such as D2 arranged behind it substantially as described.
3. The combination and arrangement of parts constituting the complete spray-
ing device substantially as described or illustrated in Figures I and 2 or in
Figures 3 and 4 of the accompanying drawings.
