This invention relates to an improvement in'cigarette machine tobacco feeds, and more particularly to novel mechanism for producing relative longitudinal movement of the concave and the pin roller, to cause the pins on the latter to remove tobacco dust which may accumulate on the inner surface of the concave. The main object of the invention, therefore, is to prevent the accumulation of lumps of tobacco dust on the inner surface of the concave. A further object is the provision of a picker roller having a periphery provided with notches forming vanes designed to create a current of air in the chute which will preventthe accumulation of dust in the chute. With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations hereinafter fully described and specifically set forth in the claims hereunto appended. 1
In the accompanying drawing which forms a part of this specification and in which like characters of reference indicate the same or like parts:
F ig. 1 is a sectional end elevation ofa portion ofthe improved cigarette machine tobacco feed; and v i F 2 is a partial side elevation, partly in cross section, showing the construction of the dust removing mechanism. 7 V
In carrying the invention into effect there is provided a rotating pin roller, a tobacco 35 chute, a rotating picker roller adaptedfto remove tobacco from the pin roller and, shower it into the chute, a concave partially surrounding saidpin roller. and means for producing relative longitudinal movement of the 1.40 concave and pin roller to cause the pins on the latter to remove tobacco dust from the inner surface of the concave. In the best forms of construction contemplated said means includes a cam actuatedreciprocating These various means and parts may be widely varied in construction within the scope of the claims, for the particular device selected to illustrate the invention is but one of many possible 0 concrete embodiments of'the same. The inning cigarette paper strip P, or a conveyor belt which is sometimes used to deliver'the vention, therefore, is not to be restricted to the specific construction shown and described.
In the improved cigarette machine tobacco feed, the tobacco picked up from the hopper by the main feed drum (not shown) is de- 5 livered onto'a feed belt 5 which runs over a roller 6 on a shaft 7 and carries the tobacco layer T towards "a pin roller 8 mounted on a shaft 9. The latter is supported by frames 10 of the tobacco feed housing 11 and carries a bevel gear 12 driven from a bevel gear 13 mounted on main shaft 14. When the tobacco T reaches the pin roller 8, it is carried by the latter over a cross member 15 supported on its two ends by the frames 10. The tobacco is then taken oil the pin roller 8 by picker roller 16, the pins of whichmove in the opposite direction and throw the tobacco T through chute 17 onto the continuously runp tobacco to the cigarette paper strip. Chute 17 is supported by brackets 18 mounted on the frames 10 and leads into the trough 19 which guides the paper strip. The shower of tobacco T in chute 17 is directed in an even stream by the flat side 20 of the concave cross member 15. Picker roller 16is mounted on a shaft 21 which on one end carries a pulley 22 driven from the main feed drive by means of a belt 23. The shaft 21 is supported by the frames 10. Y I
The shaft 9, which 0n 'one end carries a drum cam 24, has engaging in its track 25a cami'roller 26 which isfmounted on a stud supported in "a bearing 28, The latter is attached to a cross bar 29 one end'of which is slidably mounted in a slot 30 of frame 10 and the other end is likewise mounted in a slot 31 of bracket 32 which is carried by the frame 10. The bracket 32 has an'annular plate 33 which fits into an annular groove 34: of the drum cam24t. In this manner, the
tobacco dust is prevented from gathering m or lodging in the cam track 25. The bar 29 also carries aconcave 85 which partly surrounds the pin roller 8. 1
' The picker roller 16 revolves at highspeedy and therefore the notches 36 spaced at intervals on its periphery provide vanes which create an air current in the direction of their travel which winnows the dust thereby preventing the accumulation of any tobacco dust on the inner periphery of the stationary guard 37 which forms an extension of the tobacco chute. In previous tobacco feeds the pin roller 8 which revolves at a slow speed was partly surrounded by a stationary concave. This caused trouble due to the fact that the tobacco dust gathered on the inner surface of the concave and formed hard lumps, which were delivered to the shower of tobacco in the chute, and thereby being deposited onto-the continuously running cigarette paper strip,
The lumps of tobacco thus deposited in the cigarette rod would form hard spots therein which caused defective cigarettes, and in some cases even caused trouble while going through the machine, either tearing the cigarette paper or damaging parts of the machine. In the present tobacco feed the concave 35 is supported by the barf29 and'reciprocated over the pin roller by the cam 26, the stroke being such that the concave 35 traverses the distance between the circumferential rows of pins on the pin roller 8. Theends of the pins of the roller 8 being sufliciently close to the concave 35 to remove the tobacco dust from its inner periphery before it forms lumps, thus assuring a perfect cigarette rod. While the present embodim'entof the invention obtains relative longitudinal movement of the concave and pin roller by traversing the concave over the pin roller, it will be understood that the accumulation of lumps of dust on the concave may also be prevented by reciprocating the pin roller longitudinally and maintaining the concave stationary.
\Vhat is claimed is:
1. The combination with the rotating pin roller of a cigarette machine feed, of a tobacco-chute, a rotating picker roller adapted to remove tobacco from said pin roller and shower it into said chute, a concave partially surrounding said pin roller, and means for traversing the concave longitudinally of the pin roller to cause the pins onthelatterto remove tobacco dust from the inner surface of the concave. r Y
2. The combination with the rotating pin roller of a cigarette machine feed. of a tobacco chute, a rotating picker roller adapted to remove tobaccofrom said pin roller and shower it into said chute, a concave partially surrounding said pin roller, and means for traversing the concave longitudinally of the pin roller to cause the pins on the latter to remove tobacco dust from the inner surface of the concave, said means including a cam on-said pin roller, a cross bar supporting the concave and provided with a cam roller engaging said cam.

and a cam roller on said bar engaging said 1 cam.
6. The combination with the rotating pin roller of a cigarette'machine feed, of aconcave partiallysurrounding said pin roll er, and
means for traversing said concave longitudi- T nally of the pin roller to cause the pins on the latter to remove the dust which may acsaid concave, a cam roller on said cross bar engaging said cam track, and a stationary plate fitting into the circumferential groove in said cam to prevent tobacco from lodging or gathering in said cam track.
' 7 The combination with the rotating pin roller of a cigarette machine feed, of a tobacco chute, a rotating picker roller adapted to remove tobacco from said pin roller and shower it into said chute, a concave partially surrounding said pin roller, and means for producing relative longitudinal movement of the concave and pin roller to cause the pins on the latter to remove tobacco dust from the inner surface of the concave.
