My invention relates to what-is known as thermore, the water is usually separated .jfvat color printing or dyeing, or discharge from the'main portion of the box by a layer printing and particularly to ageing or of shin les to prevent" s attering the treating vat color prints or dyes or'discha-rge 'oods an by a coverin of abric such as prints or any other product Where a reduc-' urlap.

A pipe 9 forms a drain for the coni g apparatus where the heat is generated; fur densed steam which may run to the bottom 11c 5' sheet material may be anysuitable substance 'level. The interior of the box is provided with two series of rolls and 11 over which the cloth 12, being treated, passes succes- 4 sively in parallel runs as indicated in Fig.

shingles are inserted in order to give an 1 1. Between the steam pipe 7 andthe lowermost rolls 1'0, baflles 13, usually known as even distribution of the steam throughout the lower portion of the box and prevent water from spatter-ing on goods. At the u per portion of the box between and below e rolls 11 are placed a series of troughs 14 and- 14' which extend across the box from oneside to the other and are supplied with water. throu h main supply conduits or troughs 15 an 15' having branches 16 and 16' provided with valves 17 and 17 and which pa$ through the walls of the box and are adapted to discharge into the troughs 14.

The height of the water in the troughs 15 and 15 is controlled by float valves 18 and 18. connected with the water supply pipe 19. If for any reason these valves should become inactive to shut ofi. the water at the proper Point, the water would overflow the edges 0 the troughs 15 and 15' without rais- =ing itslev'el in the troughs 14 and 14'.

The box is also pre erably covered onithe sides and top with heat ,tomainproper temperature in the up er' insulating material 'such as asbestos, indicated at From the above description it will be evident that as the cloth 12 proceeds through the ageing box alternately .over the rolls 10 and 11, 1 t subjectedtothe 'vapor issuing from the surfaces of the conductive sheets 21. Thus the temperature within the box 'will' always be maintained at a point to roduce the necessary reaction and no inurious superheatedsteam will exist-therein.

' The degree "of moisture within the ageing box may be regulated by controlling the entrance of the through the valve 7 '3 and also by controlling the inlet of the water through the valves 17 and 17'. Obviously atmospheric pressure unless it should be desired to produce the reaction under a pressure less than that of atm heric pressure.'
