MACHINE FOR CARDING FLOOCULENT MATERIAL.

Specification of Letters Patent.

Patented Sept. 5, 1911.

Application filed May 2 9, 1909. Serial No. 499,217.

To all whom it may concern:

Be it known that I, JOHN ALLEN HEANY,

I a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Carding Flocculent Material, of which the following is a specification.

My invention relates to a machine for carding flocculent material such as asbestos, and delivering it to a Wire to be coated therewith.

In U. S. Letters Patent No. 825,124, granted to me under date of July 3, 1906, there is described a machine, which will sufficiently illustrate the general type of mechanism to which this invention relates.

Referring to the drawings: Figure 1 is a side view of the mechanism; Fig. 2 is a plan view of the same mechanism; and Fig. 3 is a detail view of the combing device.

Referring more particularly to the draw ings, 1 is an open-bottom hopper for containing the flocculent asbestos. Arranged to rotate within the bottom of the hopper is a wheel 2, having on its periphery card teeth 3.

4 is a metallic comb rigidly secured to a block or bar 5, having at each end thereof rollers 6, which roll in grooves 7 in guide plates 8 carried on brackets 9, which brackets are in turn mounted on side bars 10 of the machine frame (not shown). Journaled in one of the plates 8 is a shaft 11 having at its outside end asprocket-wheel 12, and at its inner end a crank-arm 13, having a crank-pin 14, to which is attached a pit-man 15, secured to the bar 5. The sprocket-wheel 12 is driven by a suitable chain 16, and sprocket-wheel 17, mounted on the shaft of the card-wheel 2. Also mounted on the shaft of the wheel 2 is a bandpulley 18, about which is a driving belt 19. This belt 19 passes around a belt-wheel 20 of larger diameter than the band-pulley 18, which is secured to the shaft 21 of a second card-wheel 22.

Mounted on the sides of the hopper are brackets 23, only one being shown. This bracket 23 has a slot in its outwardly bent flange 24, within which slides a sheet-iron guard-plate 25, pivotally connected at its lower end to the comb-plate 4. The plate 25 serves as a guard-plate to prevent the fibers from getting behind the comb-plate 4.

Fig. 3 illustrates the successive positions assumed by the comb-plate.

The operation of the device is as followsz-The card-teeth of the wheel 2 seize the asbestos fibers and carry them under the comb-plate 4, which, because of the peculiar motion given to it, effectively combs out such fibers. The block or bar 5, which carries the comb-plate 4, owing to the crank and pitman connection is given a reciprocating movement in the grooves 7 and at the same time oscillates about the rollers 63, which are in effect pivots. As will be apparent from the diagram shown in Fig. 3, the comb-plate assumes the successive position shown, 2'. 6., as it moves downward and toward the card teeth of the wheel 2 but in an opposite direction, it combs out the fibers held by the coacting card teeth; it then moves backward and away from the card teeth, but in the same direction as the cardteeth on the wheel 2, to disengage itself from the combed out fibers. The combed fibers are carried forward on the periphery of the wheel 2, until they are picked off. by the card-teeth on the periphery of the wheel 22. As this wheel 22 rotates more slowly than the wheel 2, the fibers are thus still further combed, and are then ready for delivery by the wheel 22 to the wire 23,which has been coated with a suitable adhesive to cause the fibers to be licked off as described in my prior patent. If finer combing is desired, additional card-wheels may be added.

What I claim is 1. In a machine of the class described, a carding mechanism comprising a hopper for containing the flocculent material, a cardtoothed roll arranged to rotate therein, a comb arranged to cooperate with the teeth on the roll, and means for imparting a combined reciprocating and oscillating motion to the comb.

2. In a machine of the class described, a carding mechanism comprising a hopper for containing the flocculent material, a cardtoothed roll arranged to rotate therein, a comb arranged to cooperate with the teeth on the roll, means for imparting a combined reciprocating and oscillating motion to the comb, and a second card-toothed roll arranged to cooperate with the first-mentioned roll.

3. In a machine of the class described, a

carding mechanism, comprising a hopper for containing the fiocculent material, a cardtoothed roll arranged to rotate therein, a comb arranged to cooperate with the teeth on the wheel, a block to which said comb is secured, guide plates having slots therein, pivots connected to the block and arranged to move in the slots, and means for reciproeating and oscillating the block.

4. In a carding mechanism, the combination of a comb, a block to which said comb .is secured, stationary guide plates having slots therein, pivots connected to the block and arranged to move in the slots, means for Copies of this patent may besobtained for five cents each, by addressing the Commissioner of Patents,
