The rotation of blades 3| draws the dust laden air from the housing and the dust particles upon entering the exhauster continue their travel until intercepted by the disk 32 and then follow the curvature of its surface. Lighter particles are intercepted by blades 3| which, due to their shape and rapid motion, cause the particles to be precipitated on their advancing surfaces.

From the annular collecting chamber 36 the dust is converged by means of a secondary air current maintained by the prolonger tips of the blades 3| into a receptacle 26.
What is claimed is: l

3. 'I'he combination with a tobacco stemmingI machine butt thresher having a housing provided with an outlet, of an endless traveling screen covering said outlet, a dust separator operating to suck dust-laden air out of said housing through said screen, and a rotary brush for cleaning said screen, whereby the dust is precipitatedin said separator and larger particles are excluded from the separator by said screen, said separator in.- cluding an intake communicating with the-screened outlet of the housing, a dust collecting chamber, a rotary streamlined disk within said chamber and having its rim slightlyr spaced from the interior voi said chamber to provide an annular opening into said chamber, a scroll-shaped discharge adjacent said chamber, and hyperbolo'idal blades on said disk operative upon rotation of said disk to draw the dust-laden air through said intake from the screened outlet of the housing and separate the dust from the dustladen air and deliver the dust into said chamber through the annular opening while delivering the clean air to said discharge.
4. In a tobacco leaf treating mechanism, the combination with a housing having an outlet, of meansA for gripping tobacco leaves and forwarding them with their butts exposed through said housing, means'for stripping the blade portions of the leaf from said exposed butts, a screen in said outlet, a suction conduit drawing dust-laden air through said screen, and means co-operating with said screen to remove leaf pieces therefrom.
5. In a tobacco leaf treating mechanism, the combination with a housing having an outlet, of means having opposed traveling surfaces for gripping tobacco leaves and -forwarding them sidewise through said housing, beaters in said housing for beating the leaves operating to stir up the dust and dirt thereon, a traveling screen extending across said outlet, and suction means connected to said outlet for drawing the dust stirred up by said beaters from said enclosure through said screen.
6. In a tobacco stemrningmachine, the combination with a horizontal feed table, of endless traveling supporting means on said table for forwarding tobacco leaves laid side by side thereon with the `butt portions extending in 'one direction, butt stripping means, having stripping elements moving lengthwise of said portions toward the butt ends of the leaves during the stripping operation, a housing enclosing said butt portions having an outlet facing the 'ends of said butt `portions to receive dust thrown by said elements,
and suction means arranged lto draw the dust through said outlet.
'7. In altobaccov stemming machine, the combination with means for forwarding tobacco leaves with their butts extending in the same direction, of butt stripping means acting on said butts, and pneumatic means for separating and separately delivering -the dust and the tobacco scraps resulting from the butt stripping operation.
8. In a tobacco stemming machine, the combination with devices for gripping tobacco leaves and forwarding the same side by side, of stripping mechanism for removing leaf portions from the gripped leaves, a housing enclosing said stripping means, and means co-operating with said housing to separately-deliver dust and stripped tobacco therefrom, said means including a dust outlet in said housing, suction means communieating with said outlet, and mechanism co-operating with said suction means to separate the stripped tobacco from air and dust drawn through said outlet.
