               EXCLUSIVE FEATURES OF
             THE KEIL VIBRATING SCREEN :
           1. STEP DECK—This permits the mud
             laden rejects to turn over as they cas-
             cade to the lower screen sections. This
             frees the recoverable mud and permits
             it to pass through the screen cloth. This
             results in larger screen capacity and less
             loss of usable mud.
           2 , FOU R SMALLE R SCREE N
             CLOTHS—This reduces the cloth up-
             keep to the replacement of a small sec-
             tion at a time, rather than the entire
             screen cloth when any one section
             should fail. A smaller size screen cloth
             is also easier to install, can be kept in
             more uniform tension and cannot be
             distorted like larger screen cloths when
             applied.
           3. The combination of step deck and sec-
             tional cloths also permits the use of two
             different mesh screen cloths on the same unit,   made of rubber. This reduces shut-down possibili-
             a decided advantage.                             ties because of breakage and wear. All other parts
                                                              are of steel.
           4, There are no springs, cams and loose moving parts
             on the Keil Mud Screen, all resilient parts being  5. A rugged construction throughout permits the
                                                                             Keil Screen to be operated with
