All these features are comthe innin -chember. mom and well known in cotton ins.

At each revolution of the wheel G the bar M will be moved longitudinally to the left and the breast-board D will be, opened 'correg? spon'dingly, and thus permit the partially-de- The extent of this opening will vary in accordance with the character of the cotton being treated. In

practice I have found one-inch-an-d-a-half opening of the breast-board to be very satisfactory in ginning Indian cotton, which is a short staple and small-seeded cotton. With American cotton it will be desirable to increase the extent of the opening and possibly the frequency of the openings, owing to the larger size of the seed, and in order to be ableto vary the extent of such opening of the breast-boardD, I make the connection of the lug m to the bar M adjustable, so that by shifting the lugm on the bar M the length of time of its engagement with the lug Z on the wheel G may be varied, and consequently the extent of movement of the bar M and of the breast-board D will be varied. The means for effecting the adjustment of the lugm may vary, and as illustrating one means I have shown the lug m as being provided with a' threaded stem 10, extending through a slot 11 in the bar M and provided with a clamping-nut 12; but I do not limit myself to this special means of adjustment. Whatever the extent of the opening the lug I will suddenly become disengaged from thelugmnand thereby release the bar M, and the Weight of the fall-board D, which is considerable, will cause it to close rapidly, and the impact of the projections as on the fall-board 0 will impart a jar to the gin, which Will greatly aid in separating the 'parlly-delinted seed from the cotton-roll, so they can pass down into the space b.
