Abstract
Abstract A controllable channel having an entrance and bifurcating into a pair of exits. A movable gate within the channel has three positions in which it can block the entrance, or block either one of the exits. The gate is mounted on a rotatable shaft which is aligned with the line of bifurcation within the channel. The top of the gate is convexly curved, and the shaft is rotated to place the gate in the selected position. When the gate is positioned to block either one of the exits, a sidewall of the gate will act as a portion of the channel wall for the exit that is not blocked.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
Apparatus for controlling the passage of materials or the like comprising: a bifurcated channel having an entrance and bifurcating to a pair of exits; rotatable shaft means mounted in said channel adjacent the line of bifurcation; a gate in said channel including a pair of sides each having one end connected to said shaft means and extending divergently therefrom, and including a convex top connected between the other ends of said pair of sides; means for selectively rotating said gate within said channel to a first position blocking said entrance, a second position blocking only said first exit and a third position blocking only said second exit; and a first of said sides forming a portion of a wall for the channel between said entrance and said second exit when said gate is in said second position; and a second of said sides forming a portion of another wall for the channel between said entrance and said first exit when said gate means is in said third position.
Claim 2
Dependent Claim
168 words
Apparatus for controlling the passage of materials or the like comprising: a bifurcated channel having an entrance and bifurcating to a pair of exits; rotatable shaft means mounted in said channel adjacent the line of bifurcation; a gate in said channel including a pair of sides each having one end connected to said shaft means and extending divergently therefrom, and including a convex top connected between the other ends of said pair of sides; means for selectively rotating said gate within said channel to a first position blocking said entrance, a second position blocking only said first exit and a third position blocking only said second exit; and a first of said sides forming a portion of a wall for the channel between said entrance and said second exit when said gate is in said second position; and a second of said sides forming a portion of another wall for the channel between said entrance and said first exit when said gate means is in said third position.
Claim 3
Dependent Claim
211 words
Apparatus for controlling the passage of materials or the like comprising: a bifurcated channel having an entrance and bifurcating to a pair of exits; rotatable shaft means mounted in said channel adjacent the line of bifurcation; a gate in said channel including a pair of sides each having one end connected to said shaft means and extending divergently therefrom, and including a convex top connected between the other ends of said pair of sides, the diameter of curvature of said convex top being substantially the distance from said shaft means to said top means for selectively rotating said gate within said channel to a first position blocking said entrance, a second position blocking only said first exit and a third position blocking only said second exit; and a pair of parallel extending members mounted in said channel adjacent opposite sides of said entrance; said members mounted contiguous to the path of rotation of said convex top and extending generally normal to said path; said members and said convex top sized so that both of said pair of members are contiguous with said convex top in said first position, and only one or the other of said pair of members is contiguous with said convex top in said second and third positions.
