PROVISIONAL SPECIFICATION.
An Improved Powder Distributor.
We JOSEPH TURVEY of Meopham Cottages Sevenoaks Weald, Fruiterer,
PERCY FAUCHON of Old House Farm, Hildenborough, Farmer and HARRY
STONE of Brook Cottages, Sevenoaks Weald, Hall Porter all in the County of
Kent do hereby declare the nature of this invention to be as follows :―
This invention relates to an improved apparatus for more readily and efficiently
distributing insect or other like powder and is more especially designed for use in
places where the powder is to be applied in a confined place and the apparatus is
so constructed that the powder may be efficiently distributed in whatever position
it may be held.
According to this invention the apparatus consists of a box or like receptacle
which is divided into chambers one forming a reservoir for containing the powder
and another forming an air chamber through which a current of air may be passed
by means of bellows attached to the apparatus.
The partition dividing the receptacle into chambers is perforated or formed of
wire or other like gauze and is preferably of cylindrical shape with a longitudinal
slot open to that part of the receptacle forming the reservoir for the powder.
Within the said partition a brush or brushes is or are mounted so that a
movement of rotation or partial rotation is imparted to it or them on the bellows
being operated.
This can be effected by mounting the brush or brushes on a spindle which is
provided with a crank connected by means of a rod to the bellows. By
compressing the bellows an oscillating motion is imparted through the rod and
crank to the brush or brushes thereby causing the powder to be swept through the
partition into the air chamber from which it is expelled through a distributing
nozzle by means of the current of air from the bellows.

An Improved Powder Distributor.
We JOSEPH TURVEY of Meopham Cottages, Sevenoaks Weald, Fruiterer,
PERCY FAUCHON of Old House Farm, Hildenborough, Farmer and HARRY
STONE of Brook Cottages Sevenoaks Weald, Hall Porter all in the County of

same is to be performed to be particularly described and ascertained in and by the .
following statement :-
This invention relates to an improved apparatus for more readily and efficiently
distributing insect or other like powder and is more especially designed for use in
places where the powder is to be applied in a confined space and the apparatus is
so constructed that the powder may be efficiently distributed by means of bellows
or the like in whatever position it may be held or placed for example the apparatus
may be worked by hand or it may be arranged on a carriage provided with a wheel
or wheels so that the rotation of the wheel or wheels operates the bellows and
distributes the powder.

page_text: And in order that our invention may be more clearly understood we will now
refer to the accompanying drawings which illustrate methods of carrying our
invention into effect but we do not confine ourselves to the precise details therein
set forth.
Figure 1 shews in longitudinal elevation partly in section an apparatus
constructed according to this invention and Figure 2 is an end elevation thereof
partly in section; Figure 3 shews in side elevation the apparatus arranged on a
carriage provided with a wheel or wheels from which the bellows may be driven.
Referring to Figures 1 and 2 the apparatus is formed of a box or receptacle A
divided into two chambers a' a² by a partition B having a cylindrical part (for the 1
reception of brushes D hereinafter described) formed of metal or the like perforated
at bi and with a longitudinal opening or slot at 2 open to the chamber a¹ or the
cylindrical part may be formed entirely of wire or other like gauze. The said
chamber a constitutes a reservoir for containing the powder and the chamber a² an
air chamber through which a current of air may be passed from bellows C to a
distributing nozzle a. The air passing through the chamber a² is preferably
confined to a channel as which is provided with a slot abutting or fitting tightly
against the perforated portion b¹ of the partition B and terminates in the removable
nozzle a¹.
In the perforated part of the said partition B brushes D preferably, arranged
helically are mounted in bearings d² on a cranked spindle d' which is connected by a
rod d³ to the bellows C. By compressing the bellows C an oscillating or if desired
a rotary motion is imparted through the rod d³ and cranked spindle to the
brushes D thereby causing the powder to be swept from the chamber a¹ through
the perforated partition into the air channel a³ from which it is expelled through
the distributing nozzle at by means of a current of air from the said bellows.
Figure 3 shews in side elevation the distributing apparatus constructed according
to this invention arranged on a carriage F for use more especially in hop gardens
vineyards and other like places.
A is the box or receptacle divided into two chambers a¹ a² by the partition B,
a being the chamber for the powder or the like and a² the air chamber, the latter
communicating with the bellows C C' and a horizontal distributing channel a³ which
is provided with a distributing nozzle at each end so that the powder may be
delivered on either side of the carriage simultaneously. The said air channel a³ is
slotted on its upper side permitting the powder to be swept in by the brushes D
which are mounted on the spindle d' in the cylindrical part 6 of the partition B
which is perforated at the part where it communicates with the channel a³. The
brushes may be ordinary cylindrical brushes or arranged helically preferably in
opposite directions from the centre. G is a lever centred at g on the carriage F
connected at one end 92 to one of the wheels ƒ by a rod f2 and the other end at g³
to the underside of the double bellows C C¹. c is a bar or rod rigidly attached at
its ends to the upper and lower parts of the bellows CC so that when one part C
of the bellows is compressed the other part C¹ is extended.
3
When the carriage is travelling the rotating wheel will cause the lever G to
operate the bellows C C₁ and simultaneously cause a reciprocating motion to the
brushes D through the rod f and crank arm f³ or a rotary motion may be imparted
to the brushes if desired; the powder or the like in the receptacle being swept
through the perforated partition b into the air channel a and distributed through
the nozzles on either side by the blast of air from the bellows C C¹.
By the use of the apparatus as herein before described powder can be distributed
very efficiently the brushes operating against the perforated metal or gauze or the
like causing the said powder to be delivered in even and regulated quantities.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In apparatus for distributing powder the combination with a receptacle for

page_text: containing powder and an air channel in connection therewith of a cylindrical
perforated partition and a brush for sweeping the said powder therethrough into
the air channel and means for causing a current of air through the air channel
substantially for the purpose as hereinbefore described.
2. The combination and arrangement of parts constituting apparatus for
distributing powder substantially as hereinbefore described and illustrated in
Figures 1 and 2 of the accompanying drawings.
3. The combination and arrangement of parts constituting apparatus for
distributing powder substantially as hereinbefore described and illustrated in
Figure 3 of the accompanying drawings.
