TOBACCO FEEDING MEANS FOR CIGARETTE MAKING MACHINES Filed June 19, 1954 I T 5 v v A I F I v ra HZIII-I H w uw nv m! uuuummuw INVENTOR! WILL/QM Ilsa-menu [OUDEN arr Rue The present; inventionrelates' toim'provementsin tobacco feeding means for cigarette makin'g machines, and of the kind comprisingrfai roller providedwith short pins whichfwill be hereinafter 2:5 referredv to: as a '-.carded roller, this arolleri-being so arranged, that, rotating, the pins. thereof engage with-the tobacco and'carryit round-'to a picker roller, gwhich :latter: is: also providediwith pins ,which pick *the "tobacco from; betweentthe pins. of the said, carded roller; The tobacco-"re moved by the pickenroller passes 'onto. the cigae rettejpaper; a 6;; 1" p In such arrangements as that: just described,

means are usually provided for removing excess vtobacco fromthe carded roller, such means often being in the form of a further pin carrying roller, hereinafter referred to as a brushing roller, which latter has its axis of rotation disposed in a horizontal plane above that in which is disposed the axis of the carded roller, the said brushing roller being rotated in the same direction as that in which is rotated the'carded roller and being sufliciently closeto'the latter to brush the excess tobacco therefrom. Y

Infeeding means such as just described, there is a tendency for the amount of tobacco being supplied to the carded roller to vary at different points throughout the length of the said roller owing to the thickness and/ or density of the mass of tobacco at these pointsvarying and thus in produced. I r I It'has been proposed to provide a row of tampers arranged parallel with the carded roller, the said tampers being periodically and simultaneously raised, and together allowed to fall, or lowered through the longitudinal slots of the shanks of the tampers 4; the said shaft thus acts as a guide under the action of their own weight, onto the tobacco to tamp itdown toward the "surface of the carded roller, the said tampers thus each applying the necessary pressure to the tobacco, irrespective of the thickness of the latter at the point of application, to ensure a more evenfeed.

roller is driven by a belt or chain, it is'found that a number of tampers applied simultaneously to the tobacco, to tamp it toward the surface of the said roller and so produce amore even feed, exert a braking action upon the roller, and, by so slowing down its speed, of rotation, cause a reduction in the rate at which the tobacco is delivered to the cigarette-making -machine.

Referring to the drawing, I indicates the carded roller, 2 the picker roller, and 3 the brushing roller, while 4 indicates the tampers, which are provided with slotted upwardly extending shanks 5, each of which is provided at its upper end with V a roller 6. V

Running transversely of the tampers 4 and passing through the slots therein is a shaft I, one end of which is providedwith a sprocket 8 whereby the shaft may receive motion, either from some convenient moving part, of the main machine, or provision may be made whereby it is "independently driven.

' Secured to the shaft 1 are eccentrics v9, one for each of the tampers, theroller upon each tampe engaging-its own eccentric r The eccentrics 9 new set that the tampers 4 do not act simultaneously, but, as will be clearly seen on reference to Fig. 1, whilst some are in their effective positions, others are more or less remote'from the carded roller I, so thatat no time is the weight of all the tampers acting on the tobacco.

Bythis means the Working of the feed mecha nism'is; not interfered with, and .a substantial maximum output is maintained.

Aspreviously explained, the shaft I passes for the-said tampers, a second guide being-provided to maintain the tampers in theirvertical position, this last-mentioned guide comprising a v bar or rod IU of rectangular cross-sectional out- 1 In some cases, for example when the carded line, also passing through the slots in the tampers, and being disposed in convenient spaced relationship with respect to the shaft 1.
