Abstract
Abstract The apparatus for dry packing comprises a cylindrical tube including a chamber-like portion, an air entrance-way jet-like orifice portion distally disposed in the chamber-like portion at one of the terminal ends thereof, and a venturi-like portion at the opposite terminal end of the chamber-like portion issuing into a distributing orifice-like tube exitway; a material reservoir having an exitway, the terminal end of which is suitably fastened in the chamber-like portion of the cylindrical tube between the jet-like orifice portion and the venturi-like portion.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
132 words
An apparatus for dry packing surfaces, comprising a cylindrical tube having a chamber-like portion formed by a venturi-like portion in one of its terminal ends and by a wall portion at the terminal end opposite said venturi-like portion, said venturi-like portion issuing into an orifice-like distributing portion said wall portion including an inlet disposed therein, a jet-like orifice tube selectively distally disposed in said inlet causing air under pressure from a suitable source to be blown at high velocity into said chamber portion of said cylindrical tube, a material discharge portion disposed in said cylindrical tube between said venturi-like portion and said wall portion discharging material into said cylinder portion, said chamber portion both suspending material particles therein and blowing said material particles through said venturi-like portion and said orifice-like distributing portion.
Claim 2
Independent Claim
132 words
An apparatus for dry packing surfaces, comprising a cylindrical tube having a chamber-like portion formed by a venturi-like portion in one of its terminal ends and by a wall portion at the terminal end opposite said venturi-like portion, said venturi-like portion issuing into an orifice-like distributing portion said wall portion including an inlet disposed therein, a jet-like orifice tube selectively distally disposed in said inlet causing air under pressure from a suitable source to be blown at high velocity into said chamber portion of said cylindrical tube, a material discharge portion disposed in said cylindrical tube between said venturi-like portion and said wall portion discharging material into said cylinder portion, said chamber portion both suspending material particles therein and blowing said material particles through said venturi-like portion and said orifice-like distributing portion.
Claim 3
Dependent Claim
51 words
The apparatus of claim 1 including a reservoir disposed on said material discharge portion and having a cover, a vent portion in said cover, said reservoir having means for turbulating material therein when air from said chamber portion escapes into said material discharge portion and said reservoir through said vent portion.
Claim 4
Dependent Claim
71 words
The apparatus of claim 2 including an air operated atomizing spray gun carried by said cylindrical tube, said spray gun being supplied with water under pressure from a suitable source and having an atomizing nozzle disposed at the terminal end of said orifice-like distributing portion opposite said venturi-like portion, said spray gun discharing atomized liquid particles into the path of said suspended dry material particles blown from said orifice-like distributing portion.
Claim 5
Dependent Claim
17 words
The apparatus of claim 1 wherein said venturi-like portion includes convexly curved cone-shaped walls in rectilinear cross-section.
