thermoplastics thermoplastic elastomers or combinations thereof however yokes 13 26 may also be manufactured from wood or metals without departing from the scope of this invention preferably yokes 13 26 are of i beam cross section with reinforcing braces 93 supporting the flanges 94 95 of yokes 26 13 respectively by providing reinforcing braces 93 yokes 13 26 are made as strong as possible while reducing the mass thereof it is though fully within the scope of this invention to manufacture yokes 13 26 of solid construction with smooth side surfaces 96 of side walls 17 18 and smooth side surfaces 97 of side walls 29 30 in order to provide for ease of wiping off surfaces 96 97 prior to loading clothes 50 thereupon thus yokes 13 26 may be tubular solid with mass reducing holes disposed longitudinally therethrough or of expanded thermoplastic material having internally generated closed cells preferably cables 43 44 are elastomeric coated stranded steel cables however it is within the scope of this invention to provide cables 43 44 of hemp textiles elastomeric materials uncoated steel cable or combinations of the above in braided woven twisted or straight strands or combinations thereof preferably cables 43 44 are comprised of a plurality of small diameter wound steel cable strands each cable strand wound in a first hand such as counterclockwise and the plurality of strands wound in an opposite hand ie clockwise prior to coating cable 43 44 with an elastomeric substance by winding the strands of cables 43 44 in opposite hand to the final cable structure stability.
