Abstract: <PICT:0693289/III/1> In apparatus for the dry-cleaning of garments of the kind comprising a filter F for separating the solids in the used cleaning liquid and a centrifugal hydro-extractor H for extracting the solvent from the garments, the hydro-extractor and the filter are mounted on a single rigid base so that the vibration of the hydro-extractor is transmitted to the filter with the result that solid bodies are shaken off the filter leaves or elements and sink to the bottom of the filter.  The necessity of cleaning the filter elements is rendered less frequent and the effect of the vibration of the hydroextractor is simultaneously reduced.  The rigid base comprises a rectangular girderlike frame G with holes 1a at the ends of its side members 1 for screw bolts 2 which also pass through solid rubber feet 3, the holes 1a being of larger diameter than the bolts to allow of a certain amount of play.  A washer W is also mounted on the frame and communicates with the filter by means of pipes 4 for circulating the cleaning liquid.  The filter may be a bag filter in which the filter bags 5 are supported on vertical leaves 6 communicating with horizontal tubing 7 forming a part of the circuit between the filter and the washer.  The washer W and filter F may be housed in a streamlined casing C.  To reduce further the vibration from the hydro-extractor it may be bolted to the base through resilient washers 8 on which it rests through lugs 9.  The filter may comprise a cone form of filter leaves or a filter having leaves of very fine mesh not requiring filter bags.
