THE MANNER OF USING THE 
APPARATUS. 
The dimensions of this apparatus are calculated 
for the purpose of bleaching twelve or fifteen pieces 
of + calicoes, or any other stuffs of equal breadth 
and substance. When the goods are ready for 
bleaching, the axis, L, is placed on a frame in a 
horizontal position, and one of the pieces, N, be- 
ing fastened to the canvas, M, by means of wooden 
Skewers, in the manner represented in fig. 1, it is 
rolled upon the axis by turning it with the handle, 
P. This operation must be performed by two per- 
sons ; “the one turning th a is and the other direct- 
ing ine piece, which m t be rolled on very tight 
and very even. When the first piece is on the axis, 
the next piece is fastened to the end of it by skewers, 
‘and wound on in the same manner as the first. The 
same method is pursued till all the pieces are wound 
upon the axis. The end of the last piece is then 
fastened to the canvas of the axis K. Both axes 
are afterwards placed into the cistern, with their 
ends in the sockets F F, and the lid is put on the 
’ cistern by passing the axes through the tubes H H: 
' The handle P is put upon the empty axis, and the 
pulley Q upon the axis on which the cloth is rolled, 
and the cord R, with the weight T, is put round it
