In such position the outer casing is held locked
(as shown in Fig. 3) by a pin 92 entering> a‘recess _*
931m housing section |2c (Fig. 2) and locked
25 therein by a dog 94 against displacement. To introduce the fabric into the inner container 39 through the outer casing i5 a door gen
56 is closed so as to completely and hermetically '
seal the inner container against the escape of
fluid. If the casing and container are in vertical
position they are p1aced“in horizontal position,
and the shift lever 23 is actuated to impart os
cillatory movement to the shaft 2|.
oscillation of the Shaft entails oscillation of'
both the outer casing and inner container
through the agency of therack 30 and sector 29.
After the fabrics are thoroughly cleansed, the
casing and container are placed in yertical posi
