Referring to Figure 7, the smooth roller is dispensed with and a plate 20 sloping towards the combing roller and forming a combination of the shields '8 may be used through which a reciprocating carded feeder plate 21 protrudes and feeds the tobacco as described in the case of Figure 6. In this case, the shield 8 is replaced by an extension of the plate 20 formed concentric with the surface of the combing roller.

It will be seen that by constructing the feeding devices according to this invention that the shorts are regularly carried away with the remainder of the tobacco as no opportunity is afforded for the shorts to separate from the remainder.

What we claim as our invention and desire to secure by Letters Patent is:- r

1. In a tobacco feeding apparatus the combination with a combing element, of a distributor element disposed to receive tobacco from the combing element, a feeding element to feed tobacco from a hopper to the combing element, said feeding element comprising a roller having retractable feeding spikes.

2. In a tobacco feeding apparatus the combination with a combing element, of a distributor element disposed to receive tobacco from the combing element, a feeding element to feed tobacco from a hopper to the combing element, said feeding element comprising a roller having retractable feeding spikes, and means for operating said spikes to cause the same to protrude from the roller during their passage through a hopper to feed tobacco to the combing element and to withdraw into the roller when they are not passing through the hopper.

3. In a tobacco feeding apparatus the combination with a combing element, of a distributor element disposed to receive tobacco from the combing element, a feeding element to feed tobacco from a hopper to the combing element, said feeding element comprising a roller having retractable feeding spikes pivotally mounted within the roller and a cam to operate said spikes to cause them to protrude from withdrawn into the feeding roller.

4. In a tobacco feeding apparatus the combination with a combing element, of a distributor element disposed to receive tobacco from the combing element, a feeding element to feed tobacco from a hopper to the combing element, said feeding element comprising a roller having retractable feeding spikes and a shield disposed beneath the combing element and extending from the distributor element to the feeding element to prevent the escape of short tobacco from between the combing element and the distributor and. feeding elements.

5. In a tobacco feeding apparatus the combination with a combing element, of a distributor element disposed to receive tobacco from the combing element, a feeding element to feed tobacco from a hopper to the combing element, said feeding element comprising a roller having retractable feeding spikes, means for operating said spikes to cause the same to protrude from the roller during their passage through the hopper to feed tobacco to the combing element and to withdraw into the roller when they are not passing through the hopper, and a shield disposed beneath the combing element and extending from the distributor element to the feeding element to prevent the escape of short tobacco from between the combing element and the distributor and feeding elements.

6. In a tobacco feeding apparatus the combination with a combing element, of a distributor element disposed to receive tobacco from the combing element, a feeding element to feed tobacco from a hopper to the combing element, said feeding element comprising a roller having retractable feeding spikes pivotally mounted within the roller and a cam to operate said spikes to cause them to protrude from or be withdrawn into the feeding roller, and a shield disposed beneath the combing element and exor be tending from the distributor element to the feeding element to prevent the escope of short tobacco from between the combing element and the distributor and feeding elements.
