THE INVENTOR OF THE POWER LOOM. 



MR. ANDREW KINLOCH, the first man who ever weaved at a power- 

 loom, died lately in Manchester, at the age of 90 years. In 1793, 

 he set up the first power-loom in Glasgow, the propelling power 

 being his own hand, and, after an outlay of $500, produced 90 yards 

 of cloth. Shortly afterwards he removed to Milton Printfield, where 

 forty looms were erected under his direction. In 1800, he went to 

 England, setting up looms in various places in Lancashire, and more 

 than once was in great danger of his life from the hand-loom weav- 

 ers, who were jealous of his new invention. The power-loom re- 

 mains as it was when he first invented it, with the exception of a few 

 slight improvements. 



IMPROVEMENTS IN THE MANUFACTURE OF CARPETS. 



SEVERAL new improvements in the manufacture of carpets have 

 been introduced into the English factories. One by Mr. Whytock, of 

 Edinburgh, consists in employing printed warp in such a manner that 

 all the wool is brought to the surface ; and the substance of such 

 carpeting, in place of consisting largely of wool, as heretofore, de- 

 pends on a less costly, but stronger material. By this invention the 

 simplest loom only is required ; and the designer is in no way re- 

 stricted as to variety of color. Any design of the artist may be 

 executed, however many colors may be required, increased num- 

 bers of colors not enhancing the cost. The peculiarity of this pro- 

 cess consists in printing the separate yarns of which a warp is to be 

 composed ; and this is done in such a manner that each yarn having 

 had its colors applied thereto, and the proper number brought to- 

 gether, side by side, to constitute a warp, the desired pattern is pro- 

 duced. Each yarn is wound on a cylinder of large diameter, having 1 

 a graduated scale thereon, so that children (who apply the colors), 

 having pattern-papers before them, have only to notice what colors 

 are on the successive divisions of the pattern-papers, and to apply the 

 colors, in succession, by passing color-rollers across the surface of 

 yarn wound on the cylinder, thus making simple marks of color 

 on the yarn, at intervals, which being according to the designs on the 

 papers, -when the several yarns constituting a warp come together, 

 the pattern is produced ; and the warp being woven into a fabric, with 

 raised pile by the use of wires, the most beautiful and varied results 

 are obtained." 



Another improvement lately introduced consists in printing Brus- 

 sels carpets by a process similar to block-printing, using rollers, how-
