ing the working parts more perfectly than in the two preceding figures. These 

 three figures represent a complete machine in working condition, the cutters being 

 worked by a rotatory motion, and the cloth so placed in the carriage as to be cut 

 from list to list, a, a, a, is a frame or standard, of wood or iron, firmly bolted 

 together by cross braces at the ends and in the middle. In the upper side-rails of the 

 standard, there is a series of axles carrying anti-friction wheels, b, b, b, upon which

the side-rails c, c, of the carriage or frame that bears the cloth runs, when it is pass- 

 ing under the cutters in the operation of shearing. The side-rails c, c, are straight 

 bars of iron, formed with edges v, on their under sides, which run smoothly in the 

 grooves of the rollers b, b, b. These side-rails are firmly held together by the end 

 stretchers d, d. The sliding frame has attached to it the two lower rollers e, e, upon 

 which the cloth intended to be shorn is wound ; the two upper lateral rollers/,/, over 

 which the cloth is conducted and held up; and the two end rollers g, g, by which the 

 habiting rails h, h, are drawn tight.

In preparing to shear a piece of cloth, the whole length of the piece is, in the first 

 place, tightly rolled upon one of the lower rollers e, which must be something longer 

 than the breadth of the cloth from list to list. The end of the piece is then raised 

 and passed over the top of the lateral rollers//, whence it is carried down to the 

 other roller e, and its end or farral is made fast to that roller. The hooks of the 

 habiting rails h, h, are then put into the lists, and the two lower rollers e, e, with the 

 two end rollers g, g, are then turned, for the purpose of drawing up the cloth, and 

 straining it tight, which tension is preserved by ratchet-wheels attached to the ends 

 of the respective rollers, with palls dropping into their teeth. The frame carrying 

 the cloth is now slidden along upon the stop standard rails by hand, so that the list 

 shall be brought nearly up to the cutter i, i, ready to commence the shearing ope- 

 ration ; the bed is then raised, which brings the cloth up against the edges of the
