(8.) In retorts for the distillation of shale and other bituminous substances, or for the calcining of ironstone and other substances, providing each pair of retorts with one hopper having an outlet or discharge-door situated at the lower end thereof, whereby the contents of the retorts can be discharged through the said doors, substantially as described, and shown in the drawings.
