IPC: D06F37/00
Filed: 1947-04-21
Abstract: A machine for dry-cleaning comprises a base frame 1 provided with a hollow box-like saddle 2 (or a pair of spaced saddles) open at its top and having the upper edges of its side walls arcuate, an outer stationary cylindrical fluid-receiving drum 4 seated on the arcuate edges of the saddle, power-operated rollers 13, 14, mounted in the end portions of the saddle and projecting into the drum, and a rotatable perforated washing drum 7 located within the drum 4 resting on the rollers and rotatable thereby.  In the machine shown, a hollow portion is disposed at each end of the drum 4 in the form of upstanding portions of the base frame 1 <PICT:0629026/III/1> <PICT:0629026/III/2> adapted to serve as saddles for the drum 4.  The rollers 13, 14 which are of yielding material, are mounted upon shafts 15, 16, each of which is driven by a separate motor 17, 18 on a bracket projecting from one end of the machine.  Couplings 19, 20, 23 are mounted in the shafts to permit the removal of the rollers when required, and detachable closure plates 26 are provided in the end walls of the portions 4 to allow the withdrawal of the rollers. Raised tracks are provided on the drum 7 for coaction with the rollers.  In a modification, a single pair of rollers is provided engaging the drum 7 midway of its length, the rollers then being of sufficient length to limit the rocking movement of the drum when rotated.  The drum 7 is provided with internal ribs 7a and an end opening which registers with a similar opening in the outer drum adapted to be closed by a hinged door 10.  A dump valve 11 is provided in the lower portion of the drum 4.ALSO:<PICT:0629026/IV (c)/1> <PICT:0629026/IV (c)/2> A washing-machine comprises a base-frame 1 provided with a hollow box-like saddle 2 (or a pair of spaced saddles) open at its top end and having the upper edges of its side walls arcuate, an outer stationary cylindrical fluid-receiving drum 4 seated on the arcuate edges of the saddle, power-operated rollers 13, 14, mounted in the end portions of the saddle and projecting into the drum, and a rotatable perforated washing drum 7 located within the drum 4 resting on the rollers and rotatable thereby.
