FIBER-CLEANING APPARATUS.

SPEGiFICATiON forming part of Letters Patent No. 661,749, dated November 13, 1900.

Below the trap d is a receptacle d, which is adapted to receive the foreign matter that accumulates inthe trap, said receptacle having a gate or slide d at its upper portion and another gate or slide (1 at its lower portion. When it is desired to remove an accumulation of foreign matter during the operation of the apparatus, the slide d is pushed in and the slide 01 is withdrawn, thus allowing the accumulated matter to drop into the receptacle (1, the slide (1 preventing the escape of the aircurrent Through the receptacle d. The slide (1 is now inserted and the slide (i withdrawn, allowing the matter deposited in the receptacle d to be removed.

In Fig. 5 I show a modification in which a is the casing; 17, the inlet; a, the outlet; 2= and 3, the deflectors, and d the trap.

As above stated, the outlet 0 has subs-tantially the same capacity as the inlet 7). The entire passage-way through the casing also has a capacity as great as that of the inlet b and is free from obstructions other than the deflectors described. Therefore the fibers are carried by the full strength of the air-current Without undergoing such slackening or ac celeration of speed or sudden changes of direction of movement as would tend to keep them mixed with the foreign matter, leaving 1 the latter, owing to the weight of the partideflectors.

I claim l. A fiber-cleaning apparatus, comprising i a casing having an inlet, a primary deflector opposite the inlet, against which the fibersI carried through the inlet impinge, a secondary deflector against which the fibers impinge in rebounding from the primary deflector, the two deflectors being out of alinement with each other and formed to twice abruptly change the course or direction of movement of the current of air and fibers, a trap'oi' depression ,below the secondary deflector in which the relatively heavy pieces of foreign matter detached from the fibers by the sue cessive impacts against the deflectors fall by gravitation, and a fiber-outlet located above the trap and out of alinement with the inlet, the entire passage-way through the casing, including the outlet, having a capacity as great as that of the inlet, and free from ob structions other than said deflectors.

2. A fiber-cleaning apparatus, comprising a casing having an inlet, a primary deflector opposite the inlet, against which the fibers carried through the inlet impinge, a second=v ary deflector against which the fibers impinge in rebounding from the primary deflector, the two deflectors being out of alineinent with each other and formed to twice abruptly change the course ordirection of movement of the current of air and fibers, a trap or depression below the secondary deflector in which the relatively heavy pieces of foreign matter detached from the fibers by the successive impacts against the deflectors fall by gravitation, a fiber-outlet located above the trap and out of al-ine-ment with the inlet, the

entire passage-way through the casing, in eluding the outlet, havinga capacity as great as that of the inlet, and free from obstructions other than said deflectors, and a recep-, tacle for foreign matter below the trap, said receptacle having slides or gates.

In testimony whereof I have affixed my signature in presence of two witnesses.
