the face of tlie card in loose sheets or layers^ to be " doffed" 

 or removed for spinning. 



The successive motions to form and set the teeth in the 

 leather, to complete the card, are as follow : — 



(i) The feeder, to draw the wire from a reel (in lengths 

 about i^ inch) to form the staples. 



(2) To hold the wire in the middle between the staple- 

 bar and the presser. 



(3) To cut this wire off (from the supply coil) always 

 in equal lengths. 



(4) The severed wire being held against the stapler-6ar, 

 the stapler-M;m^s are advanced so as to push forward the 

 ends of the wire to form the staples, 



(5) Two piercers or steel points are then advanced, and 

 pierce holes through the leather, just opposite the points 

 of the staples, and then they are drawn back, and descend 

 out of the way of the staple points. 



(6) The staple-bar and wings then advance with the 

 staple, the points of which are guided by the wings into 

 holes of the leather. 



(7) The staple-bar then rises above the crown of the 

 staple, and the presser advances and forces the crown home 

 against the leather. 



(8) On the opposite side of the leather are placed the 

 " crookers," or knee-benders, having loops or " eye-open- 

 ings " just above a fixed steel edge or bar, and the legs of 

 the staple are passed through these eyes, so that as they 

 descend the wires are " crooked " or bent to the proper 

 angle to form the carding surface. 



(9) All of the above-named parts return to their former 

 positions, for repeating the same motions for making and 

 setting the card-teeth, and then the sheet of leather 

 (stretched in a frame) is moved upwards, just enough to 

 set the next row of teeth, and sideways the proper distance 

 apart for the crowns of the staples, and so on continually
