HAT MANUFACTURE.
revolves, to pass it into and out of the dyeing liquor in the vat or copper. This tvhe emay be kept revolving with a very slow motion, either by gear connecting its axle; c >with any moving power, or it may be turned round by hand, at intervals of ten minutes,whereby the hats hung upon the pegs, will be alternately immersed for the space of t® aminutes in the dyeing liquor, and then for the same space exposed to the atmospher 1air. In this way, the process of dyeing, it is supposed, may be greatly facilitated animproved, as the occasional transition from the dye vat into the air, and from the 311again into the bath, will enable the oxygen of the atmosphere to strike the dye more P er 'fectly and expeditiously into the materials of which the hat is composed, than by a contin aeimmersion in the bath for a much longer time.
A variation in the mode of performing this process is suggested, and the app ar .fig. 545 is proposed to be employed, a a is a square vat or vessel containing the dye' 0 *liquor ; b b is a frame or rack having a number of pegs placed in it for hanging the l' aupon, which are about to be dyed, in a manner similar to the wheel above describe ^This frame or rack is suspended by cords from a crane, and may in that way be lower®down with the hats into the vat, or drawn up and exposed in the air; changes which O' ‘be made every 10 or 20 minutes. . -
I have seen apparatus of this kind doing good work in the hat-dyeing manufactorof London , that being a department of the business with which the Union has not thoUcit worth their while to interfere.
Mr. William Hodge's patent improvements in hat dyeing, partly founded uponinvention of Mr. Bowler, consist, first in causing every alternate frame to which ^suspenders or blocks are to be attached, to slide in and out of grooves, for the P ur P*'" i of more easily removing the ®
suspenders when required.

The patentee remarks, that it is well known to all hat dyers, that after t ^ £0 thebeen in the dyeing liquor some time, they ought to be taken out and eX P £ j iat part ofaction of the atmospheric air, when they are again immersed in the copper,, s j n thethe hat which was uppermost in the first immersion, being placed dowm . q’he
second. This is done for the purpose of obtaining a uniform and regn re ! e e arepatentee’s mode of carrying this operation into effect, is shown in the hg ^ a cr» n ®pivots for the dyeing-frame to turn upon, which is supported by the arms /, means otabove. The whole apparatus may be raised up or lowered into the copper' go pper, t»®the crane or other mechanism. When the dyeing-frame is raised out of t ie ^ u ponwhole of the suspenders or blocks are reversed, by turning the apparatus o <lyei a =>pivots e e, and thus the whole surfaces of the hats are equally acted upon jmaterial. , he c0 pp® r ’ 1
It should be observed, that when the dyeing- frame is raised up onto aS als°should be tilled on one side, so as to make all the liquor run out of tlie /' f at or l® aVecause the rims of the hats to hang down, and not stick to the body of rtheV ntee ‘a bad place or uneven dye upon it.
