represented by the metallised portion of the band, but each separate colour is, by 

 removing a very thin strip of the foil at the margin, insulated from its neighbouring 

 colour. Then all the pieces of foil thus insulated, which represent one colour or 

 shade, are connected with each other by means of small strips of tin-foil, which pierce 

 through the piper and are fastened at the back, and are conducted to a strip of tin-foil 

 which runs along the edge of the band, there being as many such strips of tin-foil as 

 there are colours. Thus each special colour of the pattern, in all its parts, is con- 

 nected by a conductor with its own separate strip of tin-foil, and by bringing the wire 

 from the pole of the battery successively into contact with the several strips, a current 

 of electricity may be made to pass in succession through the several parts of the 

 design on the band representing the separate colours of the design. Thus, assuming 

 four colours, 1, 2, 3, 4, there would bo four strips of tin-foil running the length of the 

 band, insulated from each other, each of which would bo in connection with its own 

 separate colour only. At any given moment, the thin plates of metal resting on the 

 pattern would touch in a line which, as it passes over the width of the pattern, 

 would run through all, or any one or more of the colours, but the electric current 

 would pass only through those plates which rest on the one colour represented by 

 the strip with which the pole of the battery at that instant was in contact. 



The inventor claims the following as the results of his invention : 



First. The great facility with which, in a very short time, and with precision, 

 reductions of the pattern may be obtained on the fabric by means of the varying 

 velocity with which the pattern may be passed under the teeth. 



Second. That without changing the mounting of the loom or the pattern, fabrics 

 thinner or thicker can be produced by changing the number of the weft, and making 

 a corresponding change in the movement of the pattern. 



Third. The loom and its mounting remaining unchanged, the design may be 

 changed in a few minutes by the substitution of another metallised paper having a 

 different pattern. 



Fourth. The power of getting rid of any part of the design if required, and of 

 modifying the pattern. 



WEAVING OF HAIR-CLOTH. In addition to the description of this art 

 under HAIR, a short notice is required of the best kind of shuttle for weaving hair. 

 Fig. 2113 shows in plan A, and in longitudinal section B, a shuttle which differs from

that of the common cloth-weaver only in not having a pirn enclosed in the body of 

 the box-wood, but merely an iron trap a, which turns in the middle upon the pin b. 

 This trap-piece is pressed up at the one end, by the action of the spring c, so as to 

 bear with its other end upon the cleft of the iron plate d, which is intended to hold 

 fast the ends of the hair- weft : d and c together are called the jaws ' or ' mouth,' whence 

 the popular name of this shuttle. The workman opens this jaw by the pressure of 

 his thumb upon the spring end of the trap a, introduces with the other hand one or 

 more hairs (according to the description of hair-cloth,) into the mouth, and removing 

 his thumb, lets the hairs be seized by the force of the spring. The hairs having one 

 end thus made fast are passed across the warp by the passage of the shuttle, which is 

 received at the other end by the weaver's left hand. The friction rollers, x, x, are 

 like those of fly-shuttles, but are used merely for convenience, as the shuttle cannot 

 be thrown swiftly from side to side. The hand which receives the shuttle opens at 

 tiie same time the trap, in order to insert another hair, after the preceding has been 

 drawn through the warp on both sides and secured to the list. A child attends to 

 count and stretch the hairs. This assistant may, however, be dispensed with by
