Verde chute display Queen mine tour
The Verde chute design came to Bisbee from Jerome (United Verde Branch) in the1940’s. The simple design was easier to install than previous chute designs used in Bisbee and quickly became the dominate type used.
Unlike the other designs it requires the operator to stand off the track level at an elevation equal to the chute lip. Standing on the platform the operator, usually the motor swamper would place the chute handle in the groove. Lifting upward on the chute handle, the door would open allowing the muck to fill the car below. Verde chutes give the swamper great control on the flow of material coming from the raise, this helps prevent spillage. (spills usually cause the mine car to derail when pulled forward) When a car is full, ( rocker dump cars must have heaping load to dump easy) the swamper signals the motorman with his light to move the train forward for the next car. The swamper will spot the mine car under the chute lip to load by using various light signals to the motorman. After a train is full the swamper get down from the chute stand and ride the last mine car to the pocket with the motorman to help dump the train.
Different versions of the Verde chute were made, E & K car, H Car, Special Verde and one that the chute door was opened by an air cylinder.
