DRIVING HECHANISH FOR CIGARETlTE MCINB.

- ploy a cigarette forming mechanism or cigarette machine proper Aoperating at constant speed, together with an automatic feed mechanism therefor. It is well known in the lart tl'iat in preparing tobacco for cigarette manufacture succeeding lots are not always in the isaine order or condition, and that whatever the order or condition when the tobacco is repared its condition is subtochan fore manufacture into oigates, the c ange being due to changes in `inospheric conditions or carelessness in handling the tobacco. It is also well known that when there is any .change in the condition of the tobacco m a feed mechanism, there is a' corresponding change in the, rate of feed because the action of the unchanging parte` 0f the feed mechanism upon the tobacco diifeiawith its condition. Such feedinechanilms therefbolre havealwa s b een ,'lul'pped w a varia e s mec a-nism .by 'means of which the ratreif feed couldA be changed hen change occurred in the co dition of l lingo.

The quantit of tobacco on this forwarding belt was su cient for about l thousand cigarettes` and at the usual speed At which these machines were operated it took about three minutes for a shredI to travel from the disentan ling mechanism 65 along the forwarding bet to the picker Speclcaton of Letters Patent.

In f his machine the operator usually discovers that a change has occurred in the coiditioof the tobacco by a change in the densit 'of the cigarettes made; that is to say, he Aiscov'eirs that they are running toohard orto soft, as the case may be.
