PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Applying Paint or other
Compositions to Surfaces.
I, JOSEPH FELL REDMAN, M.1.N.A., of Gallions, Royal Albert Dock, in the
County of Kent, Marine and Engineering Superintendent, do hereby declare the
nature of this invention to be as follows:-
According to this invention streams of paint or other composition and air are
forced along a flexible hose and issue at its end in the form of spray.
The paint or other composition is introduced into a cylindrical or other shaped
vessel provided with an air pump by which air can be forced into its interior. On
the top of the vessel is a nozzle to which the hose is attached. This nozzle has a
central opening surrounded by an annular opening the former being connected to a
pipe leading to near the bottom of the vessel and the latter being connected by
a pipe to the top of the vessel so that the one delivers paint or other composition
and the other air. Each of these pipes is furnished with a cock.
The air suction is connected to a coil of pipe below the bottom of the vessel so
that when the vessel is placed above a fire or lamp both the paint or other com-
position and the entering air are heated so that the paint or other composition can
be applied hot without risk of its being cooled in the vessel or hose by the stream
of air.

1, JOSEPH FELL REDMAN, M.I.N.A., of Gallions, Royal Albert Dock, in the
County of Kent, Marine and Engineering Superintendent, 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:-
According to this invention streams of paint or other composition and air are
forced along a flexible hose and issue at its end in the form of spray.
The paint or other composition is introduced into a cylindrical or other shaped
vessel provided with an air pump by which air can be forced into its interior. On
the top of the vessel is a nozzle to which the hose is attached. This nozzle has a
central opening surrounded by an annular opening the former being connected to
a pipe leading to near the bottom of the vessel and the latter being connected by a
pipe to the top of the vessel so that the one delivers paint or other composition and
the other air. Each of these pipes is furnished with a cock.
The air supply is connected to a coil of pipe below the bottom of the vessel so
that when the vessel is placed above a fire or lamp both the paint or other com-
position and the entering air are heated so that the paint or other composition can
be applied hot without risk of its being cooled in the vessel or hose by the streamn

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical central section of an apparatus constructed according to
this invention and Figure 2 is a half plan of the same.
Figure 3 is a longitudinal section of the cock and nozzle to a larger scale and
Figure 4 is a transverse section on the line 4-4 Figure 3.
a is the vessel containing paint or other composition and b is a pipe leading air
from a pump or reservoir (not shown in the drawings) through the central coil and
into the vessel a. It will be observed that the lower end of the pipe b is directed
tangentially, the object of this is that the incoming air may stir the paint. The
vessel a is provided with a manhole a', filling opening a, handles a³ and a safety
valve and pressure gauge the latter not being shown. c is a pipe whose lower end
reaches nearly to the bottom of the vessel a and whose upper end is connected to
the central passage e of the cock d. The annular passage f surrounding the
passage e leads directly into the top of the vessel a. The passages e and fare
provided with plug taps e and respectively and they are connected by the
coupling 9 with a socket to which are fixed the ends of two concentric hose
pipes and k. Preferably flexible metallic hose is employed. At the other end of
the hose is a nozzle. This consists of two parts a socket having an inner and
outer tube connected by radial distance pieces and a cap m.
Figures 5 and 6 are longitudinal and transverse sections of a modified form of
nozzle. In this case the cap m is screwed to the socket . The screws n of this
arrangement used to regulate the area of the orifice may be adopted in the nozzle
shown in Figure 3.
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 reservoir for paint or other composition, means for
forcing air into the reservoir, pipes by which the paint or other composition and
the air are led from the reservoir and a nozzle connected to the pipes.
2. The combination with apparatus such as is referred to in the preceding claim
of means for heating the air before it reaches the reservoir.
3. In apparatus such as is referred to in the preceding claims arranging the
pipes the one within the other.
4. Apparatus for applying paint or other composition substantially as described
and shown in the drawings.
