Abstract
Abstract A vertical conveyor having a pair of endless belts forming a run between which articles are conveyed. Infeed and discharge chutes are located along the run at a point where one of the belts is removed to interrupt and expose the run. Switch means are provided at the exposed portion to divert the containers to or from the run.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A conveyor for the vertical transport of articles comprising a pair of endless belts cooperating to form a moving run for said articles, one of said belts being interrupted along its length to expose said run, an infeed chute and discharge chute associated with said exposed run, a switch member mounted between said chutes and said exposed run said switch selectively moveable between a first position blocking said discharge chute and extending said infeed chute and a second position extending said disCharge chute to said exposed run, and gate means for blocking said infeed chute at least when said switch member is in its second position, whereby said articles may be selectively fed to or removed from said run.
Claim 2
Dependent Claim
119 words
A conveyor for the vertical transport of articles comprising a pair of endless belts cooperating to form a moving run for said articles, one of said belts being interrupted along its length to expose said run, an infeed chute and discharge chute associated with said exposed run, a switch member mounted between said chutes and said exposed run said switch selectively moveable between a first position blocking said discharge chute and extending said infeed chute and a second position extending said disCharge chute to said exposed run, and gate means for blocking said infeed chute at least when said switch member is in its second position, whereby said articles may be selectively fed to or removed from said run.
Claim 3
Dependent Claim
50 words
The conveyor according to claim 1, including a sensor located along said run prior to said exposed run for producing a signal indicative of the presence of an article in said conveyor and motive means for moving said gate means in to said blocking position in response to said signal.
Claim 4
Dependent Claim
30 words
The conveyor according to claim 2 wherein said gate means is normally biased out of blocking position and said motive means for actuating said gate means comprises a solenoid actuator.
Claim 5
Dependent Claim
51 words
The conveyor according to claim 2, wherein said sensor produces a signal indicative of the presence of an article to be removed at said discharge chute, and including motive means moving said switch member in response to said second signal from said first to second position to open said discharge chute.
Claim 6
Dependent Claim
58 words
The conveyor according to claim 4, wherein said infeed and discharge chutes are arranged one above the other and include common wall members having an opening leading to said exposed run, said switch member having a tongue extending therefrom bridging the distance between said exposed run and the chute openings and pivotable into cooperative association with each respectively.
Claim 7
Dependent Claim
55 words
The conveyor according to claim 5, wherein the tongue of said switch member has a planar outer surface conforming to the surface of the continuous belt at the exposed run portion, said switch means being movable into a third position wherein said surface cooperates with said belt to continue said run beyond the interrupted portion.
Claim 8
Dependent Claim
30 words
The conveyor according to claim 6, wherein said switch means is normally biased in its first position and the motive means for operating said switch member comprises a solenoid actuator.
