Improvements in Instruments for Distributing Ink or Pigments in
the Form of Spray.
I, JOHN JAMES LINZELL, of 17 West Harding Street, Fetter Lane, in the County
of Middlesex, Artist, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in that class of instrument used for
distributing ink or pigments upon any suitable surface by means of a current of air,
and the object is to construct the same in as small a compass as possible, so that it
may be held in the hand in the same manner as an ordinary brush or pencil.
The air is supplied from a reservoir, through a flexible tube to the main tube of the
instrument, which is held in the hand like an ordinary brush or pencil. This main
tube is fitted with an air-tight valve, worked by a thumb lever, for admitting or
cutting off the supply of air to the instrument. A jet of air is conducted through
this tube to the point of the needle, which latter passes through a horizontal duct
or palette containing the ink or pigment and will consequently cause the ink or
pigment to be deposited on the surface to be drawn upon, by a spray. To this main
tube is connected a branch tube, the outer end of which is provided with holes or a
slot behind the wind wheel, and the current of air will cause the wind wheel to
revolve. The wind wheel is fixed in hearings on a frame capable of sliding upon the
side plate, to or from the duct or palette. The frame forms part of, or is connected
to a slide mounted on the main tube, and by pushing the slide up or down on the
tube, the wind wheel is pushed nearer to the duct or palette or drawn farther away.
The outer end of the axis of the wind wheel is provided with a small crank, the pin
of which is formed at an angle to the axis of the wind wheel, and which works in the
slot of a piece which carries the needle, the slotted piece working horizontally in the
line of the needle. The pin of the crank is arranged parallel to the slide on
the main tube.

page_text: In order to make a fine spray, the slide piece on the main tube is drawn upwards
and the wind wheel is at its farthest point from the duct or palette; the crank will,
therefore, only cause the needle to move backwards or forwards to a limited extent,
and consequently supply but a small quantity of ink or pigment. On the other hand,
when it is required to throw spray broadly, the slido piece is pushed downwards on
the main tube and the wind wheel will be nearer to the duct or palette, and the
throw of the crank greater the needle will consequently travel farther forward and
supply more ink or pigment. It will be seen that on account of the pin of the crank
being parallel to the slide on the main tube, the movement of the latter upwards or
downwards never alters the backward position of the needle, but simply causes it to
move more or less forward.
It will be readily understood that the supply of ink or pigment may be regulated
between the two extremes, according to requirement, by manipulating the slide on
the main tube between the top and bottom position.
The whole of the mechanism for working the needle is enclosed in a box by means
of a removable cover and consequently lessens the risk of the instrument getting
out of order.
The instrument is fitted with a ring, for the insertion of the middle finger, in order
to give more command over same.

Improvements in Instruments for Distributing Ink or Pigments in
the Form of Spray.
I, JOHN JAMES LINZELL, of 17 West Harding Street, Fetter Lane, in the County
of Middlesex, Artist, 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 invention relates to improvements in that class of instrument used for
distributing ink or pigments upon any suitable surface by means of a current of air,
and the object is to construct the same in as small a compass as possible, so that it
may be held in the hand in the same manner as an ordinary brush or pencil.
The air is supplied from a reservoir, through a flexible tube to the main tube of
the instrument, which is held in the hand like an ordinary brush or pencil. This
main tube is fitted with an air-tight valve, worked by a thumb lever, for admitting
or cutting off the supply of air to the instrument. A jet of air is conducted through
this tube to the point of the needle, which latter passes through a horizontal duct or
palette containing the ink or pigment and will consequently cause the ink or pigment
to be deposited on the surface to be drawn upon, in a spray. To this main tube is
connected a branch tube, the side of which is provided with holes or a slot to blow
upon one side of the wind wheel, and the current of air will cause the wind wheel
to revolve. The wind wheel is carried by a frame capable of sliding upon the sido
plate, to or from the duct or palette. The frame forins part of, or is connected
to a slide mounted on the main tube, and by moving the slide up or down
on the tube, the wind wheel is moved nearer to the duct or palette or drawn
farther away. To the outer end of the axis of the wind wheel (if the axis is
made to revolve in its bearings with the wheel) is provided with a small crank,
the pin of which is formed at an angle to the axis of the wind wheel, and
which works in the slot of a piece which carries the needle, the slotted piece working
horizontally in the line of the needle. The pin of the crank is arranged so that it is
parallel to the slide on the main tube when in its extreme backward position.
If the axis of the wind wheel is stationary and the latter revolves thereon, the
crank pin will then be attached to the end plate of the wind wheel instead of to
the axis.
In order to make a fine spray, the slide piece on the main tube is drawn upwards
and the wind wheel is at its farthest point from the duct or palette; the crank pin
will, therefore, only cause the needle to move backwards and forwards to a limited
extent, and consequently supply but a small quantity of ink or pigment. On the
other hand, when it is required to throw spray broadly, the slide piece is pushed
downwards on the main tube and the wind wheel will be nearer to the duct or palette,

page_text: and the throw of the crank pin greater; the needle will consequently travel farther
forward and supply more ink or pigment. It will be seen that on account of the pin
of the crank when in its extreme backward position being parallel to the slide on the
main tube, the movement of the slide upwards or downwards never alters the backward
position of the needle, but simply causes it to move more or less forward.
But in order that my invention may be more clearly understood I will proceed to
describe the same referring to the accompanying sheet of drawings, in which Fig. 1
is a front elevation and Fig. 2 a side elevation of the instrument, the box for
containing the mechanism being closed. Fig. 3 is a side elevation in which the slide
piece is drawn upwards to its farthest position for the purpose of making fine spray,
the box being open to show the mechanism. Fig. 4 is a side elevation, showing the
mechanism, in which the slide piece is pushed downward to its lowest position for
the purpose of making broad spray, the box also being open. Figs. 5 and 6 show
letails of the mechanism for working the needle.
The air is supplied to the main tube A through the inlet tube B which is connected
to the air reservoir by a flexible tube. The supply of air is regulated by an air-tight
valve, worked by the thumb lever C. A jet of air is conducted through the tube A
to the point of the needle D, which latter passes through the horizontal duct or
palette E containing the ink or pigment, and will consequently cause the ink or
pigment to be deposited on the surface to be drawn upon in a spray. To the main
tube A is connected a branch tube F, the side of which is provided with holes or a slot
to blow upon one side of the wind wheel G, and the current of air will cause the
wind wheel to revolve. The wind wheel G is mounted on a shaft H fitted in the
bearing I carried by the frame J capable of sliding on the side plate P, to or from
the duct or palette. The frame J forms part of or is connected to the slide L mounted
on the main tube A, and by moving the slide L up or down on the latter the wind
wheel G is pushed nearer to the duct or palette E or drawn farther away. The
outer end of the axis II of the wind wheel G (if the axis is made to revolve in its
bearings with the wheel) is provided with a small crank, the pin of which is formed
at an angle to the axis of the wind wheel, and which works in the slot of the pivoted
arm M which carries the needle D, the slotted piece working horizontally in the
line of the needle.
The pin of the crank is arranged so that it is parallel to the slide L on the main
tube A when in its extreme backward position. If the axis F. of the wind wheel G
is stationary, and the latter revolves thereon, the crank pin K will then be attached
to the lower end plate N of the wind wheel G instead of to the axis. As above
explained in order to make a fine spray the slide piece L on the main tube A is
drawn upwards, and the wind wheel G is at its farthest point from the duct or
palette E. The crank pin K will, therefore, only cause the needle D to move
backwards and forwards to its smallest extent, and consequently supply but a small
quantity of ink or pigment. On the other hand, when it is required to throw spray
broadly, the slide piece L is pushed downwards on the main tube A and the wind
wheel G will be nearer to the duct or palette E and the throw of the crank pin K
greater the needle D will consequently travel farther forward and supply more
ink or pigment. It will be seen that on account of the pin K when in its extreme
backward position being parallel to the slide on the main tube the movement of the
latter upwards or downwards never alters the backward position of the needle, but
simply causes it to move more or less forward.
It will be readily understood that the supply of ink or pigment may be regulated
between the two extremes, according to requirement, by manipulating the slide L
on main tube A. between the top and bottom position.
The whole of the mechanism for working the needle D is enclosed in a box by
means of a removable or hinged cover and consequently lessens the risk of the
instrument getting out of order.
The instrument is fitted with a ring O for the insertion of the middle finger, in
order to give more command over same.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The improved instrument for distributing ink or pigments in the form of spray,
substantially as specified.
2. Mounting the whole of the parts of the instrument for delivering ink or pigments
in the form of a spray upon a hollow stem or handle which is connected with an air
pump or supply of compressed air and can be held in the hand so as to serve to
manipulate such instrument and also to convey the current of air to actuate and act
upon the needle and produce the spray, all substantially as specified.
3. Providing a perforated or slotted tube leading from the hollow stem or handle
to a suitable position near the wind wheel so as to actuate same, substantially as and
for the purpose specified.
4. The means for transmitting the movement of the wind wheel to the needle and
regulating the movement of the latter, consisting in the use of a crank pin secured
to such wheel and formed at an angle to the axis thereof, the crank pin working in
a slot in a pivotted arm to which the needle is connected, and the wind wheel being
mounted so that it can slide to and fro in the frame all substantially as specified.
5. Causing the wind wheel to move in a line parallel with the hollow stem or
handle and arranging the inclined crank pin attached to such wheel so that when in
its extreme backward position it is in a line parallel with the hollow stem or handle,
so that the movement of the wheel in the frame will not affect the rearward stroko
of the needle, but only the forward stroke of same, substantially as specified.
6. Attaching the wind wheel to a slide capable of being moved up and down on
the hollow stem or handle of the instrument, substantially as specified.
