The upper portion of the apparatus is raised, bythe handle P, and the lower end of the bobbin is placed onthe lower cone, C; the upper portion is now lowered, sothat the upper cone fits in the upper end of the bobbin, andis pressed into position, being held by the catch and slot,V, The vessel T is tten filled with the liquid, which is heatedif necessary, and which is pumped through L and I/, andsprayed over the fabric by means of the perforated cones,thus ensuring even treatment of the whole of the complete machine is made up of a number of sucharrangements connected with the same liquid reservoir. —T.
