The Mather and PiattSteamer Kier, see Fig. 55and 5€, consists of a liori-zontftl cylindrical, wroughtiron boiler or kierwiih theends slightly curved togive it strength. One endis stationary while theother consists of a heavywedge shaped door D,raised and lowered by ahydraulic lift L, and which when lowered wedges itself steam. 112 TEXTILE CHEMISTRY AND DYEING. 103 tiglit into the frame F. In the bottom of the kier is a track T,on whicli the two tracks or cars CC, can be run in and cars are constructed of galvanized iron; are providedwitli a perfoiated bottom and liohl the goods during the boilingprocess. When the goods liave been eveidy packed in the cars,they are run into the kier, the door is closed and all the airexpelled from the kier by the admission of steam.
