MEMOIR OF DANIEL TREADWELL. 



right and left (Figs. 3 and 5), so locking and unlocking with the wheels g and g\ The slide-bar oo is 

 made to move by the following described apparatus. A long shaft or axle, rr (Fig. 3), passes horizon- 

 tally from under the slide-bar o o to the right hand, as seen in the drawings, until it projects beyond the 

 frame a a. [In Fig. 2 this shaft is supposed to be broken off under the drawing-roller ss, at the right 

 hand of the drawing-frame, and the left-hand part removed.] rrr is hung in centres which are fixed in 

 the iron bearing, ss, at the extreme right of Figs. 1, 3, and 4. Gd is an iron brace to keep s from 

 springing. The arm t passes horizontally from the right end of rr, and the arm t 1 rises vertically from 

 the other end (Fig. 5), directly under the slide-bar o o. v is a bent lever, the fulcrum being a pin which 

 passes through and unites it to the bearing w, which is fixed to the frame a a. The vertical arm of the 

 lever v is fixed in the bottom of the slide-bar, and the horizontal arm of the same lever is connected with 

 the weight, y, as seen in Fig. 5, and also in dotted lines in Fig. 1. This lever and weight draws the 

 slide-bar constantly to the right. The rod la la (Fig. 4) is united to the horizontal arm t on the shaft 

 rr by a movable joint, and passes upward to the cross-bar 2a 2a (Figs. 1 and 4). The rod la passes 

 through the middle of 2a, and receives a thumb-nut upon its top. The connecting rods da 3a pass from 

 the ends of the cross-bar 2a, and are united by pins to the levers q q, one rod uniting to each lever. It 

 is in holes in these levers that the upper roller, s, runs. The lever q is seen detached in Fig. 9.

passing through a round hole in its centre, and proper collars are fixed to the shaft, on each side of it, to 

 prevent it from sliding in the direction of the shaft. A wooden lever, 6a 6a (Fig. 3), passes from a 

 point near the star-wheel horizontally to a point directly under the gatherer, x (Fig. 1). This lever 

 turns on a fulcrum in the pillar la, fixed to the frame a. The other end of the lever is just capable of 

 reaching the star- wheel, which throws it up whenever the star- wheel is turned round for that purpose. 

 Ab (Fig. 5) is a little click attached to the frame ee, which passes up through a hole or slot in the slide- 

 bar by the side of the lever 6a, and slips under its end whenever it is caught by the star-wheel above the 

 top of the click, and holds it up. But this is only done so long as the slide-bar carries the clutch-box I 

 so far to the left that the catch m' no longer touches the point of the star-wheel. The click is so ar- 

 ranged as to slip out from under the end of the lever Ga, which is pulled down by the weight, bb (Fig. 1), 

 attached to it. To the top of the lever 6a, near its right end, as seen in Figs. 1 and 3, is united by a 

 hinge-joint the cross-bar Ob, to each end of which are fixed rods, lb lb, which pass directly upwards 

 through guide-holes in the piece of cast iron, w, each side of the gatherer, x, and on the outside of the 

 same, and are fixed by their tops to the comb 8*. The comb is formed of several rows of iron teeth 

 riveted to an iron plate. The several rows of teeth are directly over the slits in the top of the gatherer, 

 x, which have been before described, and when forced downwards pass through these slits into the rov- 

 ing of hemp which is in the gatherer. Two cast iron pillars, Ob, at the lower right-hand corner of Fig. 1, 

 are fixed to the frame a ,y, and rise above and on each side of the lever Ga. A small lever, lc, is placed 

 between the pillars 9b, directly over the lever Ga, and is hung upon a pin which passes through 9b9b near 

 their tops, and through lc. This pin forms a fulcrum or axis on which lc turns. To the right end of 

 lc, as seen in Figs. 1 and 3, there is connected, by a movable joint, the rod 2c, which passes directly up- 

 wards through guide-holes in the piece of cast iron w, and the bottom of the gatherer. The left end of 

 the lever lc, as seen in Figs. 1 and 3, is connected with the lever Ga by hooks. It will readily be per- 

 ceived by this description and the figures, that, when the right end of the lever 6a is depressed, the right 

 end of lc will be elevated and carry the rod 2c upwards, which will lift the false bottom, before described. 

 of the gatherer, the teeth of the comb passing, at the same time, through the slits made in the false bot- 

 tom of the gatherer.^ Upon the shaft b b (Fig. 4) is fixed the pulley 3c, from which a belt passes to and 



(Fig. 3). Upon the shaft A A (Fig. 3) is fixed the 



(Fig. 1) 



// 



the shaft 7c, which, by inspection of Fig. 1, will be seen to drive the pulley b, which moves the 



hatchel-belt c.
