Apparatus for producing patching material for filling potholes in paved surfaces
First Claim
1. An apparatus for producing patching material for filling potholes in paved surfaces comprising:
- (a) a hopper means for holding a quantity of pulverulent material, said means having an opening for receiving said marterial from a source and a transport tube means in the bottom of said hopper means, said tube means having an inlet opening connected to a source of air under pressure and an outlet opening connected to a discharge nozzle, said transport tube means also having an intake opening intermediate said inlet and outlet openings to receive said material into said transport tube means, and means adjacent said intake opening to cause said material to be drawn into said tube by said air flowing under pressure in through said intake opening and out through said outlet opening;
(b) means between said outlet opening and said discharge nozzle to dissipate part of the air stream so that said material will not be blown out of said pothole during filling; and
(c) means adjacent said discharge nozzle for introducing an emulsion to combine with said material prior to its discharge from said nozzle into said pothole.

Abstract
An apparatus is disclosed for producing patching material for filling potholes and the like in paved surfaces which includes a hopper for receiving a quantity of pulverulent material, a tubular discharge mechanism in the bottom of the hopper which employs the Venturi effect created by air under pressure to draw the material into the tube and discharge it through an opening and means for controlling the flow of material into the discharge mechanism. A nozzle is connected to the discharge opening and has means adjacent the orifice thereof for introducing a quantity of asphalt emulsion into the stream of material for mixing therewith prior to discharge from the orifice into the pothole or the like to be filled.
