The piece of cloth to be shorn is wound upon tho beam k, and its end ib then con- 

 ducted through the machine, between the flat springs /and g (as shown in Jig. 2136), 

 to the other beam I, 

 and is then made fast ; 

 the sides or lists of the / ^\ 



cloth being held and | Q / f\ 



stretched by small II |_th 

 hooks, called 'habit- 

 ing hooks.' The cloth 

 being thus placed in 

 the machine, and 

 drawn tight, is held 

 distended by means of 

 ratchets on the ends 

 of the beams k and 

 I, and palls. In com- 

 mencing the opera- 

 tion of shearing, the 

 carriage a must bo 

 brought back, as in 

 Jig. 2136, so that the 

 cutters shall be close to the list ; the frame of tho cutters is raised up on its pivots 

 as it recedes, in order to keep the cloth from injury, but is lowered again previously

to being put in action. A band or winch is applied to the rigger or pulley i.i, which, 



by means of an endless cord passed round the pulley n, at the reverse eud of the axle 



of m, and round the other 



pulleys o and p, and the small 



pulley q, on the axle of the 



cylindrical cutter, gives the 



cylindrical cutter a very rapid 



rotatory motion ; at the same 



time a worm, or endless screw, 



on the axle of m and n, taking 



into the teeth of the large 



wheel r, causes that wheel to 



revolve, and a small drum s, 



upon its axle, to coil up the 



cord, by which the carriage d, 



with the cutters a and e, and 



the spring bed /' and g, are 



slowly, but progressively, made 



to advance, and to carry the 



cutters over the face of the 



cloth, from list to list ; the 



rapid rotation of the cutting 



cylinder , producing the operation of cropping or shearing the pile. 



Upon tho cutting cylinder, between the spiral blades, it is proposed to place strips 

 of plush, to answer the purpose of brushes, to raise the nap or pile as the cylinder 

 goes around, and thereby assist in bringing the points of tho wool up to the cutters. 



The same contrivance is adapted to a machine for shearing the cloth lengthwise.
