PROVISIONAL SPECIFICATION.
Improvements in and relating to the Floating or Blowing of
Granulated Cork, Sawdust, or like Material, on Painted or
other Adhesive Surfaces.
We, JAMES HARVIE MEIKLE, Glass Merchant, and JAMES HARVIE MEIKLE, Junior,
Manager, both of 50, Kelvingrove Street, in the County of the City of Glasgow,
do hereby declare the nature of our invention to be as follows:-
This invention has reference to improvements in and relating to the floating
or blowing of granulated cork, sawdust, or like material on painted, varnished or
other adhesive surfaces, such as warships, and the like.
According to our improvements we place the granulated cork or like material
in a tank or vessel in the bottom of which is fitted a feeding screw or other con-
veyor. The screw feeds the cork into a hopper on a pipe branch connection and
a jet of compressed air is passed through a nozzle on a branch of pipe preferably
placed at right angles to hopper. This causes a suction action to draw the cork
from hopper and force it through a flexible pipe which would be fitted with an
end nozzle to project the cork on to the prepared surface to which it is to adhere.
The spindle of screw feeder would be driven by band gearing and pulleys from
a fan operated by a jet of compressed air from a branch pipe attached to com-
pressed air pipe, the respective pipes being fitted with regulating valves or stop
cocks.

COMPLETE SPECIFICATION.
Improvements in and relating to the Floating or Blowing of
Granulated Cork, Sawdust, or like Material, on Painted or
other Adhesive Surfaces.
We, JAMES HARVIE MEIKLE, Glass Merchant, and JAMES HARVIE MEIKLE, Junior,
Manager, both of 50, Kelvingrove Street, in the County of the City of Glasgow,
do hereby declare the nature of our invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement, that is to say:-
This invention has reference to improvements in and relating to the floating
or blowing of granulated cork, sawdust, or like material on painted, varnished or
other adhesive surfaces, such as warships, and the like.

page_text: And in order that our said invention and the manner of carrying same into
practice may be properly understood we have hereunto appended a sheet of expla-
natory drawings in which Figure 1 is a side elevation, partly in section, and
Figure 2 an end view representing appliances for carrying our improvements
into practice, while Figure 3 is a detached sectional elevation of the feed hopper
and suction apparatus.
Referring to these drawings:-
According to our improvements we place the granulated cork or like material
in a tank or vessel A in the bottom of which is fitted a feeding screw B or other
conveyor. The screw B feeds the cork into a hopper C¹ on a pipe branch connec-
tion C and a jet of compressed air is passed through a nozzle D on a branch of
pipe preferably placed at right angles to hopper. This causes a suction action
to draw the cork from hopper C¹ into a chamber C where a partial vacuum is
formed, and force it through a flexible pipe E which would be fitted with an
ordinary end nozzle to project the cork on to the prepared surface to which it is
to adhere.
The spindle B¹ of screw feeder B would preferably be driven from the pulley B2
by band gearing B³ 13 and pulleys from a fan operated by a jet of compressed
air from a branch pipe b attached to compressed air pipe, the respective pipes
being fitted with regulating valves or stop cocks F F.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is: :—
The method of floating or blowing granulated cork, sawdust, or like material on
painted, or other adhesive surfaces, substantially as set forth.
