27,582. Welch, W. H., and Frost & Co., H. Dec. 18. Digesters.-Vessels for treating substances under steam pressure and particularly vulcanizers are made of a flattened shape with the mouth disposed in a plane substantially at right-angles to the flattened sides for example as shown in Fig. 1, the cross-sectional area of the vessel being small compared with its capacity. The cover A' may be pivoted and is closed tight by means of a yoke D and screw D<2>, which may also be employed for opening the cover by causing the screw D<2> to impinge upon a tail-piece D'.
