Fig, 5 is a cross-section of the axle of the draw-boy and figure box. 

 Figures 1 and 2 are drawn to a scale of three-fourths of an inch to a 

 foot; and figures 3, 4, and 5, to a scale of two inches to a foot. 



The same letters of reference refer to the same parts in each figure. 

 A A A is the frame of the loom; B, the roll or beam on which the 

 warp is put; C, the cloth or breast roll; D D, the lay or bottom; E, 

 the reed ; F F, a frame which supports and regulates the table of mul- 

 lets; G, the table, which consists of a number of thin bars, fixed in a 

 frame nearly in a vertical position, but which can be elevated or in- 

 clined at pleasure, by a hoop H. Betu'een each of these thin small 

 bars, are placed one, two, three, or more, small mullets or pulleys ccc^ 

 over which pass the horizontal strings or tail d cl d, by which the 

 Iambs or headles II, J J, and K K, are suspended. 



To weave plain cloth, only two leaves of headles are really neces- 

 sary; but, in fine webs, where many threads are contained in the warp^ 

 the number of headles required in one shaft, would be so great, that 

 they would be crowded together, which would cause unnecessary 

 friction, and strain the warp. For this reason, a greater number of 

 leaves is used in weaving figured silks, &c. The number of these 

 leaves is so great, that thd shafts on which the headles are placed, are 

 obliged to be arranged in two, three, or more stages, one above an- 

 other, as shown i-n figures 1 and 2, at 1 1, J J, KK; so that, when the 

 lowest set of headle shafts I I, are raised to make the sheds, or opening 

 in the warp, through which the shuttle passes, they are in the situa- 

 tion of those at i i, and do not rise so high as to interfei-e with those 

 at J J; and, when those at J J are raised tojj, they do not interfere 

 with those at K K; and those at K K will be raised to kk. So, by this 

 arrangement, there will be three times the number of the leaves of 

 headles, in nearly the same space, as when placed on the same level. 



To each of the lower treadle shafts, are suspended three long 

 small leaden weights / / /, so as to keep the treadles straight and 

 perpendicular. The strings d d d^ which suspend the treadles, are 

 extended across the room, and are made fast to a horizontal rod L; 

 which is also fixed by cords to the side of the room. M is a bar or 

 roll, which is suspended from the ceiling of the room, to support the 

 string or tail d d, &c. N is another roll, which is, itself, supported 

 by a frame from the upper part of the loom, and supports the strings 

 d d, &c., when the depression is made on them by the action of the 

 fuot on the treadles 0, F F, Q Q, from which the motion is com- 

 municated to the draw-boy, &c. R R is the frame of the draw-boy, 

 which must be fixed to the floor. 



S is a square wooden bar or axle of the draw-boy, mounted so as to 

 turn backwards and forwards on two screwed centres e e, figures 2, 3, 

 4, fixed in the ends of the frame R R. There are also fixed to each 

 end of the frame R R, and concentric to the axis of tlie screwed cen- 

 tres e c, a cylindrical ring m and ii, figures 3, 4, of brass or iron. One 

 end of each ring is made flat, with an internal flanch, for fixing it to the 

 end of the frame, and tho other ends of the rings arc formed into in- 

 clined planes. On the upper side of the axle S are inserted, in two
