PROVISIONAL SPECIFICATION.
Improvements in and relating to Appliances for Spraying Liquids
on to Surfaces.
I, JAMES HARVIE MEIKLE of 19 Royal Terrace, West in the City and County
of Glasgow do hereby declare the nature of my invention to be as follows:-
This invention has reference to appliances for spraying oil paint or other liquid
fluids, on to buildings on other surfaces, being improvements upon that described in
the Specification of my former Patent No. 10541 of 1894.
According to my present improvements I form a vertical hollow cylindrical oi
An air pipe
other shaped vessel with close top and removable bottom covei.
would be coupled to a branch at the top of this vessel, and the other end of this
pipe would be coupled to a metal branch connected to the mam air pipe. The
lower end of vessel would preferably be formed of tapered or hopper shape and a
portable disc bottom with curved oi semi-circular lugs would be secured to same
preferably by the lugs fitting through bolts or screw pins cast on vessel and secured
by outs outside One or more bianches each fitted with regulating valves would
be formed through this bottom cover, and to which would be coupled the ends of
a flexible pipe oi pipes leading to the central tube of an air blast spray nozzle.
The main an pipe from air compressor of reservon would be coupled to a branch
In the outer annular casing of this nozzle apparatus so as to spray the liquid paint
passing by the central tube through the outer nozzle on to the building or other
su lace
Valves would be fitted to regulate or control the liquid and au supply.
By this means the compressed air passing through the branch would act on top
of paint or liquid in supply vessel and force it out through the branch in bottom
cover and conveying pipe to the nozzle apparatus, where the eurient from main all
pipe will meet it and spiny it on to the surfaces to be coated.
A vertical cential spindle would be fitted in vessel having its lower end resting
in a hollow boss formed in bottom cover, and having its upper end passing out
through a stuffing box at top of vessol Two or more 1adial 'arins or vanes would
be secured at distances apart by collars and screw pins to this spindle, and a crank
handle would be mounted at top of spindle outside of vessel so as to rotate the
spindle and agitate or mix the paint and the like A hole covered by a screw
plug would be formed at top of vessel for filling it with the paint or material to be
mixed and sprayed.

Improvements in and relating to Appliances for Spraying Liquids
on to Surfaces.
1, JAMES HARVIE MEIKLE, of 19 Royal Terrace, West, in the City and County
of Glasgow do hereby declare the nature of my invention and in what manner the
Baine 18 to be performed to be particularly described and ascertained in and by
the following statement in writing, that is to say :-
-
This invention has reference to appliances for spraying oil, paint, whitewash, or

page_text: other liquid fluids, on to buildings or other surfaces being improvements upon that
described in the Specification of my formor Patent No 10,541 of 1894
And in order that my said invention and the manner of performing or carrying
same into practice may be properly understood, I have hereunto appended an
explanatory sheet of diawings in which the same reference letters Aic used to
indicate corresponding parts in all the figures where shown.
Figue 11s an elevation of the complete appliance Figure 2 is a plan view of
same, and Figure 3 is a vertical section corresponding to Figure 1
Figure is a detached view of the air combining pipes
Figure 5 is a detached view of the paint and an combining nozzles, and
Figure 6 is a detached sectional view of the paint nozzle
Referring to these drawings .-
According to my present improvements I form a vertical hollow cylindrical or
other shaped vessel A with removable top cover A and lose bottom A¹ and
supported by vetted-on legs A* An an pipe a would be coupled to a branch a¹
at the top of this vessel A, and the other end of this pipe would be coupled to a
metal branch, connected to the main a pipe b. The lower end A' of vessel
would preferably be formed of tapered or hopper shape, and a portable screwed-on
cap A would be fitted to same. The top A of vessel would consist of a
portable disc with a ring of rubbor A* or the like for an tight packing and be
secured by pins changed at c on side of vessel A eutering slits in cover A³, said
pius being formed with top lugs . One or more bianches B each fitted with
regulating valves B' would be formed though the bottom A' of vessel A and to
which would be coupled the ends of a flexible pipe or pipes B2 leading through a
cock B to the central tube B' of an au blast spray nozzle 13. The main air
pipe from an compressor on resei von, would have branches to which the end
of flexible pipes would be coupled, and the other ends of these pipes would be
each coupled to a branch B the outer annulai casing of each nozzle
apparatus B, so as to spray the liquid paint passing by the central tube B* B*
through the outer nozzle B on to the buildings or other surfaces, the liquid and an
supply being regulated by the cocks
b
By this means the compressed an passing through the branch a' would act on
top of paint or liquid in supply vessel A. and force it out through the branch Bin
bottom and conveying pipe B to the nozzle apparatus B3 B+ where the curient
through the branch pipes from main au pipe will meet it and spray it on to
the surfaces to be coated. When whitewash is being sprayed the central nozzle
would be like that shown in Figure 5, but when paint is to be sprayed, the orifice
would be smaller as in Figure 6
A vertical central spindle C would be fitted in vessel A having its lower end
resting in a hollow boss cap A'in bottom of vessel and having its upper end passing
out through a stuffing box C¹ at top of vessel Two or more adial aims or
vanes C would be secured at distances apart preferably by straps and rivets at C³
to this spindle C and a crank handle C would be mounted at top of spindle
outside of vessel so as to rotate the spindle C and agitate or mix the paint and the
like. A hole covered by a screw plug would be formed at A* at top of vessel A
for filling it with the paint or material to be mixed and sprayed.
Having non particularly described and ascertained the nature of my said inven-
tion and in what mannei the same is to be performed I declare that what !

The arrangement and combination of appliances for spraying liquidɛ on to
surfaces, substantially as herein descubed in reference to and shown in the
accompanying drawings.
