500 MEMOIR OF DANIEL TREADWELL. 



right and left (Figs. 3 and 5) , so locking and nnlocking with the wlieols (/ and g'. The slide-bar o o is 

 made to move by the following described apparatus. A long siiaft 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 bej'ond 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 liung in centres which are fixed in 

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

 springing. The arm t passes horizontally from the rigiit end of rr, and the arm V rises verlicallv from 

 the other end (Fig. 5), directly under tiic slide-bar oo. v is a bent lever, tlie 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 tlie 

 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 weiglit draws the 

 slide-bar constantly to the right. The rod 1« la (Fig. 4) is united to the horizontal arm i on the shaft 

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

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

 the ends of the cross-bar 2a, and are united b}- pins to the levers qq, 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. 



In addition to the parts heretofore described as connected with the shaft /"/"there is placed upon that 

 shaft the star-tcheel, 4a (Fig. 5), a side view or elevation of which is given detached in Fig. 12, and on 

 the shaft of Fig. 10 and Fig. 3. The star-wheel is fitted to the shaft// like the wheels g, g', the shaft 

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

 prevent it from sliding in the direction of the shaft. A wooden lever, Ca Ca (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 fuleniin 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 e e, 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 b3- the star-wheel above the 

 top of the click, and holds it up. But this is only done so long as the slide-liar 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 6a, which is pulled down by the weight, 5b (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 Gb, to each end of which are fixed rods, lb lb, which pass directl}' 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 bj- their tops to the comb 8b. 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, 9S, at the lower right-hand corner of Fig. 1, 

 are fixed to the frame a a, and lise above and on each side of the lever 6a. A small lever, Ic, is placed 

 between the pillars 95, directly over the lever Ca, and is hung upon a pin which passes through Obdb near 

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

 Ic, 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 Ic, as seen in Figs. 1 and 3, is connected with the lever Ga b}- hooks. It will readil}' be per- 

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

 end of Ic 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 bb (Fig. 4) is fixed the pulley- 3c, from which a belt passes to and 

 over the pulley 4c (Fig. 1), fixed upon the shaft// (Fig. 3). Upon the shaft hh (Fig. 3) is fixed the 

 pulley be (Fig. 1), and from the pulley 5c a belt passes to and over the pulley 6c, which is fixed upon 

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

 hatchel-belt c.
