Marsh-Mud. 



NOTE D. 



" To an iron frame, 4 feet breast and 3 feet high, is 

 attached in front, in a horizontal position, a 2 inch 

 roller, covered with the best kind of sole-leather, 

 grooved (say 1.16th of an inch deep) diagonallj- — the 

 grooves being an inch apart. Pressing hghtly against 

 this roller, from the centre upwai-ds, and confined 

 to its place by small steel clamps, is a very thin steel 

 plate, made perfectly smooth and beveled on the un- 

 der side, which comes in contact with the roller. On 

 each end of this roller is a pulley, connected with 

 other puUeys by bands. The Cotton is placed on a 

 feeding-board, and drawn in by the action of the 

 roUer between it and the plate the entire length of 

 the fibre, (the seed exposed and resting against the 

 plate.) where it is held firmly. In the mean time a 

 vibrator (which is a plate of iron 2 inches broad with 

 square notches in the upper edge, and screwed to a 

 piece of wood to support it ) attached to two upright 

 pieces of wood an inch square, which are attached 

 to each end of an iron shaft (li inch in diameter and 

 placed in a horizontal position.) by means of sUding 

 cranks, which give an eccentric motion, and cause it 

 (the \-ibrator) to play up and down with great velo- 

 city, just clearing the plate ; pushing the seeds up- 

 wards; clearing the Cotton, wnich, thus relieved, 

 passes on (the leather or ginning roller being.cleared 

 by a smaUer one resting on it, and lying just behind 

 the plate) to an endless apron. 8 inches broad, which 

 is made to revolve on two rollers of li inch diame- 

 ter, and which is placed in close proximity to the 

 srinning-roller. The cleaning-roller passes the Cot- 

 fon under another roller di inch diameter) to the 

 apron, around which it adheres, and by this process 

 the fibre is straightened. 



"The apron is cleared, after thirty revolutions, by 

 means of a cam, which is placed over the apron, near 

 the back pan of the gin ; the edee of this cam is 

 made to come resrularly down to the apron by a fin- 

 ger attached to one end of it; a racket-wheel throws 

 this finger under a segment of a circle, attached to 

 the pulley which drives the {nnning-roller, and thus 

 holds the cam to the apron during one revolution ; 

 the edge of the cam is then brought clear of the 

 apron by weights and the Cotton falls to the floor in 

 a bat 



"The above is the plan of the gin as first exibited. 

 I have since simplified it somewhat by taking ofl^ the 

 apron, cam, &c. and substituted 4 rollers in their 

 place — placing them imraediatelv back of the sin- 

 (.-OR) " 



ning and clearing rollers, through which the Cotton 

 passes and falls in flakes on the floor." — [Eirroct of a 

 letter from H. W. Fargo of Savannah. Mr. M' Carthy's 

 agent for Georgia, to the writer.] The price of a 

 single gin is $150.
