disposed on substantially parallel axes, said nozzle struc
ture provided with guide means for slidably supporting
said elongated nozzle plate and providing for the ready
disassembly of said nozzle plate from said nozzle struc
ported in said grooves.
5. A portable device for the removal of snow and ice
from aircraft and other surfaces comprising a fabricated
nozzle assembly having an air inlet adapted for connec
ture, and a removable closure means disposed at one end
of said guide means for securing said nozzle plate in
position with respect to said nozzle outlet, handle means
tion with a source of heated compressed air, a hollow
nozzle structure having a pair of spaced side Walls, handle
means secured to each of said side walls, conduit means
adapted for connection to a source of ice inhibiting agent
and carried in one of said handles, means connected to

connection to a source of ice inhibiting agent carried in
one of said handles, a dispersing means connected to
said conduit being operable to selectively disperse a ?ow
of ice inhibiting agent into the heated air directed through
said conduit and carried in one of said trapezoidal-shaped
walls and being operable to dispense said agent into said
heated compressed air, valve means disposed in said
handle means, said valve means being operable to con
trol the ?ow of ice inhibiting agent to said dispensing
2. A portable snow and ice removal device as de?ned
in claim 1, wherein handle means are attached to dia
metrical opposite external portions of said device to
facilitate handling of same.
3. A portable snow and ice removal device as defined
in claim 1, wherein adjustable handle means are attached
to diametrical opposite external portions of said device,
