AIR-SEPARATOR.
the finer particles of previously ground or comnimuted material are separated from the massand,particularly, to that class of sepa- .rators wherein the separation is obtained by subjectingthe mass of material centrifugally discharged within an inner casing to the weighing or winnowing action of an ascend- ,ing air current which carries the finer articles nto a separate outer casing where t icy may be collected.
In separators of this class it is preferable to secure a continuous circu ation of the 8.11.
current within the apparatusrather than to draw the air supply from outside, as the latter method ives rise to back pressure and 3 is otherwise objectionable. But the difiiculty'hitherto experienced in using 'a continuous return circulation of air within the casings has been that the opening from the outer into the inner casing is located in such proximity to the fan which creates the air current that the descending current in the outer casing loadedwith' the fine separated particles of material is prematurely drawn again into the inner casing. This causes a re-w-innowing of the already so arated materialwith consequent waste 0 power and loss in the out ut of the separator, due to the same materia being, so-to speak repeatedly re separated.
gkMyobject is to obviate the above-mentioned defect in this class of separators by so arranging and adjusting the cas' s as to increase or decrease at will the pat traversed by the return current of air within the casings. This I. accomplish by the means herein described and shown in the accompanying drawing in which- Figure l is aview, in vertical section, of the entire separator. Th; consists of the outer casing 1 mounted upon suitable supports 2 and provided with the discharge outet 3.

The hollow rotary shaft 21 extends vertically downward through the top of the outer casing 1 into the upper portion of the inner casing 4 and is actuated by any suitable means, such as the horizontal shaft 22, pulley 23 and gears 24 and 25. The shaft 21 carries-thefans 26, adapted to rotate in the space between the to of the inner and outer casings. The disc large plate 27 is secured to the lower end of the shaft 21. ipe 28 is mounted within the rotary 1101 ow shaft 21 by the bearing 29 at the top of the latter and extends downward to a point a little above the discharge plate 27. the hopper 30 and the shield 31, the function of the latter being to protect the gears 24 and 25 from any overflow from the happen.
