can be indwendentiy c (His-(5., ca 6% 1 U :1 010581 and a em a base the fiver k ma lithe? 0 adjusted position in a similar manner, as shown in our Patent #1,114,985, dated October 27, 1914, whereby each of the deck frames will be allowed to be adjusted independently in order to change the inclination thereof so as to adjust the inclination of the supporting surface carried thereby, which will be later described, whereby any one of the frames can be adjusted independently of the other to allow the classifying surface to be adjusted to suit the class of material being sized.

The deck framesare provided with suitable bearings at each end in which are mounted shafts 5 and (l carrying rollers 7 and 8 on which are mounted endless flexible belts 9, 10, 11 and 12 arminged to deliver the material progressively from the upper .belt to the lower belts, These belts are preferably provided with longitudinally arranged corrugations increasing in depth from the upper edge toward the lower edge thereof, but it isof course understood that any form of belt having a roughened surface can be employed for carrying out the process of sizing the material.

Each of the shafts G is provided with a pulley 13 over which passes the drive belt 14 driven by change-speed mechanism A subst'antially\ as shown in our companion Patent $21,114,935, in order that the speed of each belt can be cont-rolledl i Mounted intermediate the shafts 5 and 6 in each of the deck frames, is a shaft 15 carrying an angular tapering roller 16 constructed substantially as disclosed in our Patent #1,114,935, dated October 27, 191 1. The shafts 15 carrying the angular rollers 16 extend outwardly beyond the upper side bar of the respective frames and are provided with beveled gears 17 which mesh with beveled gears 18 carried by shafts 19 mounted in suitable bearings; said shafts carrying pulleys 20 over which pass drive belts 21 driven by a change-speed mecha nism B constructed substantially as disclosed in our Patent #1,114,935, dated October 27, 1914, whereby the speed of vibration. of the belts can be independently con trolled.

The construction of the several units as hereinbefore described, is substantially the same and the description of one is sufficient for all, as each is operated in the same manner that the adjacent unit is operated, but is under an independent control and from the foregoing description, it will be seen that a sizing apparatus is provided composed of a number of units capable of being adjusted independently in order to change the inclination of the surface and that the speed of travel ofthe belt and the vibration thereof can also be controlled independently.

Arranged at the delivery end of each of the sizing surfaces 9, 10 and 11, is a series of spaced deflecting baffles 22, disposed in such a position to receive and deliver the sized particles from the upper sizing surface to the next lower sizing surface in such a manner that the particles are prevented from racing or bouncing.

The deflecting baffles 22 conform to the curvature of the roller over which the belts pass, but are spaced slightly theref: m and are arranged as clearly shown in Figs. 2 and 3 forming a number of channels which extend obliquely in order to receive the material and deliver the same to the next succeeding surface at a higher point, aswill be later described. These baffles are'preferably formed of angled plates supported by any suitable means, not shown, in the position as disclosed in Figs. 1, 2 and 3.

By constructing a sizing apparatus composed of a series of units, having deflecting baffles arranged to receive and deliver the material from one sizing surface to another, the particles are caused to travel a greater distance over the sizing surface than would be the case with an apparatus without the deflecting battles, and by giving the baffles a crook at their lower ends, the movement of the particles is arrested when they are delivered to the sizing surface so as tolprevent the same from racing or bouncing. The division of these baffles into narrow channels facilitates the transfer of the particles from one sizing surface to the next succeeding surface without altering materially the degree of sizing, so far as the progress upon the preceding surface is concerned, and at the same time, the particles are advanced and delivered to the next succeeding surface at a higher point. This can be readily understood by referring to the diagrammatic view illustrated by Fig. 3, where the approximate inclination of the sizing surface is shown with reference to the perpendicular line KK, the dotted line terminating at M showing the travel of the particles through the deflecting baffies.

The particle N on reaching the roller travels from the point (30 to'til and thence to 62 on the next succeeding surface, and is delivered at the point M, while if it was allowed an unrestricted line of travel under the influence of gravity and the agitation of the sizing surface, it would report at L.

A suitable apron is arranged at the delivery end of the sizing surface 12 and is provided with a spaced bar Ql under which are adjustably mounted lingers 25 for de fleeting the sized particles delivered from the last sizing surface of the apparatus into suitable receptacles and it is of course understood that while we have shown such an apron for this purpose, the same can be dispensed with and the sized particles de- '10 of the succeeding surface, progressively varying the speed of transport upon the suc- -i 'cessive supporting surfaces, and separately collecting the separated sizes of material from the last supporting surface.

8. The process of sizing material, consisting in transporting material composed of grains of varying sizes on a series of successive supporting surfaces inclined transversely to the direction of transporting movement, and subjecting said material to gravitative impulses adapted to deviate the components of said material from the direction of transport in proportion to their respective sizes, delivering the material in distributed condition from one surface to progressively increased extents of the succeeding surfaces, progressively varying said gravitative impulses upon the successive supporting surfaces, progressively varying the speedof transport upon the successive supporting surfaces due to delivery from one surface to the next, and separately collecting the separated sizes of material from the last supporting surface.

9. In a machine for sizing solid material, a series of independently adjustably mounted continuously moving sizing surfaces arranged in line of continuous movement and inclined transversely to the direction of continuous movement, means for transporting material discharged from the end of one continuously moving surface in distributed condition to progressively increased extents of the succeeding surface, progressively vary- 45 ing the speed of travel of the successive continuously moving surfaces, and means for separately collecting the separated sizes of material discharged from the last supporting surface.

'10. In a machine for sizing material, a series of continuously moving sizing surfaces arranged in line of continuous movement andinclined transversely to the direc tion of continuous movement, means for transferring material in distributed condition from the end of one continuously moving surface to the next succeeding surface so as to advance the material in its trans- 'ferring movement, progressively varying 60 the speed of travel of the progressively moving surfaces, and means for separately collecting the separated sizes of material discharged from the last supporting surface.

11. A machine for sizing material, composed of grains of varying sizes, comprising a series of successive continuously moving supporting surfaces inclined transversely to the direction of the continuous movement,'

means for vibrating said surfaces to cause the components of said material to deviate from the line of continuous movement in proportion to their respective sizes, means for transferring material in its distributed condition from one surface to progressively increased extents of the succeeding surface, means for driving the successive continuously moving surfaces at different rates of speed, means for progressively varying the inclination of said surfaces, and means for collecting the different sizes of material discharged from the last surface.

12. A machine for sizing solid material, composed of grains of varying sizes, comprising a series of successive continuously moving supports inclined transversely to the direction of continuous movement, means for vibrating said supports to cause the compo nents of said material to deviate from the line of continuous movement in proportion to their respective sizes, means for progressively varying the speed of movement of said supports, a series of spaced ed fleeting baflies arranged at the end of each of said supports for transferring material in its distributed condition from one surface to a higher point on the adjacent surface, and means for collecting the separate sizes of material from the last supporting surface.

13. In a machine for sizing solid material, a series of laterally inclined and longitudinally progressing separating surfaces, means for transferring material in distributed condition from one surface to the adjacent surface so as to advance-the material in its transferring movement, mechanism for im parting agitativc n'iovel'uent to said surfaces, progressively varying the speed of travel of the progius ively moving surfaces, and means for separately collecting the separated sizes of material discharged from the successive sui'iporting surfaces.
