Abstract
Abstract For applying a liquid coating to a selected portion of a flat article such as an insole there is provided a machine including a pair of endless belt conveyors arranged in longitudinal spaced alignment parallel to and in juxtaposition to a third endless belt conveyor; a reservoir disposed above the space between the first pair of conveyor belts and arranged to discharge a vertical liquid curtain of a suitable coating composition down through the space between said pair of conveyors. Above the third conveyor is a fourth conveyor disposed in alignment with the third conveyor and long enough at least to span the space between the first pair of conveyors and so mounted as to cooperate with the third conveyor to grip one end of an article being conveyed jointly by said pair of conveyors and the third conveyor, the result being that the article is held in predetermined position as the liquid curtain deposits liquid on that surface of the article which extends beyond the grip of the third and fourth conveyors.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
A machine for applying liquid to a selected portion of a flat article, which comprises a pair of longitudinally aligned spaced endless belt conveyors, means disposed above said conveyors for directing a thin curtain of liquid downwardly through the space between said conveyors, a third endless belt conveyor mounted in closely spaced parallel relation to said pair of conveyors and extending substantially the combined lengths of said pair of conveyors, and a fourth endless belt conveyor disposed above and parallel to said third conveyor, the belts of said third and fourth conveyors being disposed to grip an article between them.
Claim 2
Dependent Claim
100 words
A machine for applying liquid to a selected portion of a flat article, which comprises a pair of longitudinally aligned spaced endless belt conveyors, means disposed above said conveyors for directing a thin curtain of liquid downwardly through the space between said conveyors, a third endless belt conveyor mounted in closely spaced parallel relation to said pair of conveyors and extending substantially the combined lengths of said pair of conveyors, and a fourth endless belt conveyor disposed above and parallel to said third conveyor, the belts of said third and fourth conveyors being disposed to grip an article between them.
Claim 3
Dependent Claim
21 words
The machine defined in claim 1 wherein means is provided for driving all of the conveyor belts at the same speed.
Claim 4
Dependent Claim
125 words
A machine for applying liquid to a selected portion of a flat article, which comprises a pair of longitudinally aligned spaced endless belt conveyors, means disposed above said conveyors for directing a thin curtain of liquid downwardly through the space between said conveyors, a third endless belt conveyor mounted in closely spaced parallel relation to said pair of conveyors and extending substantially the combined lengths of said pair of conveyors, and a fourth endless belt conveyor disposed above and parallel to said third conveyor, the belts of said third and fourth conveyors being disposed to grip an article between them, said fourth conveyor being substantially shorter than the third conveyor and disposed to overlie the third conveyor opposite the space between said pair of conveyors.
Claim 5
Dependent Claim
125 words
A machine for applying liquid to a selected portion of a flat article, which comprises a pair of longitudinally aligned spaced endless belt conveyors, means disposed above said conveyors for directing a thin curtain of liquid downwardly through the space between said conveyors, a third endless belt conveyor mounted in closely spaced parallel relation to said pair of conveyors and extending substantially the combined lengths of said pair of conveyors, and a fourth endless belt conveyor disposed above and parallel to said third conveyor, the belts of said third and fourth conveyors being disposed to grip an article between them, said fourth conveyor being substantially shorter than the third conveyor and disposed to overlie the third conveyor opposite the space between said pair of conveyors.
Claim 6
Dependent Claim
111 words
A machine for applying liquid to a selected portion of a flat article, which comprises a pair of longitudinally aligned spaced endless belt conveyors, means disposed above said conveyors for directing a thin curtain of liquid downwardly through the space between said conveyors, a third endless belt conveyor mounted in closely spaced parallel relation to said pair of conveyors and extending substantially the combined lengths of said pair of conveyors, a fourth endless belt conveyor disposed above and parallel to said third conveyor, the belts of said third and fourth conveyors being disposed to grip an article between them, and means for driving all of said conveyors at the same speed.
Claim 7
Dependent Claim
111 words
A machine for applying liquid to a selected portion of a flat article, which comprises a pair of longitudinally aligned spaced endless belt conveyors, means disposed above said conveyors for directing a thin curtain of liquid downwardly through the space between said conveyors, a third endless belt conveyor mounted in closely spaced parallel relation to said pair of conveyors and extending substantially the combined lengths of said pair of conveyors, a fourth endless belt conveyor disposed above and parallel to said third conveyor, the belts of said third and fourth conveyors being disposed to grip an article between them, and means for driving all of said conveyors at the same speed.
Claim 8
Dependent Claim
21 words
The machine defined in claim 4 wherein the fourth conveyor belt spans the space between said pair of endless belt conveyors.
Claim 9
Dependent Claim
130 words
A machine for applying liquid to the surface of the rear portion of an insole, comprising a pair of longitudinally aligned spaced conveyor belts, means for directing a curtain of liquid downwardly through the space between said belts, a third conveyor belt parallel to said pair of belts and in juxtaposition thereto, said third belt being substantially as long as the combined lengths of said pair of belts, and a fourth conVeyor belt disposed above and in contact with said third belt, whereby an insole may be so disposed that its rear portion is carried on said pair of belts and its forepart portion carried on said third belt, the third and fourth belts cooperating to grip the forepart portion of the insole to hold it in fixed angular position.
Claim 10
Dependent Claim
130 words
A machine for applying liquid to the surface of the rear portion of an insole, comprising a pair of longitudinally aligned spaced conveyor belts, means for directing a curtain of liquid downwardly through the space between said belts, a third conveyor belt parallel to said pair of belts and in juxtaposition thereto, said third belt being substantially as long as the combined lengths of said pair of belts, and a fourth conVeyor belt disposed above and in contact with said third belt, whereby an insole may be so disposed that its rear portion is carried on said pair of belts and its forepart portion carried on said third belt, the third and fourth belts cooperating to grip the forepart portion of the insole to hold it in fixed angular position.
