Application filed November 2 1-, 18-24:.

In the case of the devices hitherto known for threshing, grinding or pulverizing the work is done by friction or beating and consequentl-y such devices have all the d1sadvantages connected with this kind of work, of which the most serious consist in the fact that 1. The material to be worked absolutely must be completely dry;

2. The output of such devices, in comparison with the power consumed, is very small.

The process forming the subject-matter of the present invention and the apparatus for carrying it out remove the abovementioned disadvantages in a simple and appropriate manner by the fact of their being based on centrifugal force, owing to which the work is simplified and proceeds quite independently of the condition of the materials.

One constructional form of such an arrangement is illustrated in cnoss section in Figure 1. Figure 2 shows partly an elevation and partly a section on the line AB in Figure 1. Figure 8 is an elevation, and Figure 4 a plan. In Figures 5, 6, 7 and 8 details are illustrated.

In the constructional form illustrated the present invention consists of a drum 1 provided on its inner surface with teeth 18 (Figures 1 and 2), the said drum being secured in a casing 2, and of a disc 3 fastened in the interior of the drum 1 on the rotatable shaft 4 which does not pass through the centre driven in any desired manner, for exam ple by means of a belt drive, the discs 3 dividing the drum 1 into two chambers, 9 and 10. The chambers 9 and 10 are of different diameters, and the larger chamber, 10, is pro vided in the lower part with sieves inserted in grooves 7. The two parts of the drum 1 are connected to one another by screws 8, which serve at the same time for fastening the drum 1 to the casing 2.

The disc 3 is arranged in the one chamber 10 in such a manner that its edge lies in the. vicinity of the second chamber 9. On both sides of the discs 8 are arranged grippers secured with screws 12, there being, in the smaller chamber, three of the said grippers, 11, which do not reach the centre of the ad mission aperture 13, and also the grippers 11*, the number of which depends on the di- Serial No. 751,998.

mensions of the apparatus as a whole but a 11, the numberof which is also dependent upon the dimensions of the apparatus, and which are likewise equipped with attachments secured with screws 16 and having sharp points 15, the ends 17 of which pass over the disc 3 into the chamber 9. The grippers 11 are erected at a definite angle, in order to prevent the apparatus from becoming choked with the material.

The method of working of the apparatus is as follows The shaft 4, and with it the disc 3, is set in rapid rotation at about 1200 to 1500 revolutions per minute, and the material is then admitted to the apparatus through the inlet 13, where it is set in incipient rotation by the grippers 11 and consequently arrives at the grippers 11 which impart to it quicker motion, in which'case for example the plants separate for the most part from the husks or shells, and the entire mass rotating is seized by the ends 17 of the spikes 15 and thrown over the disc 3 into the chamber 10, where by the action of the grippers 11 it is set in very ra id rotation, with which there co-operates t e eddy of air arising here by virtue of the fact that the disc 3 is not secured at its centre. Under the action of the centrifugal force caused by the rapid rotation and of the air eddy the plants are for example separated from the shells, which in this case for the most part remain whole.

The working space may if desired be enlarged or diminished according to the kind of work required, which may be simply effected by sliding its two parts towards or away from one another, by means of screws for example, which may be applied to the sides of the drum 1, and which are not shown in the drawing.

Uf course the apparatus may be designed with different constructional modifications wthout going outside the bounds of the invention described.

hat I claim is 1. Apparatus for disintegrating plants and other materials including a casing, a

drum secured to said casing and having two internal diameters, a rotatable shaft passing through the axis of the drum, a disc secured to said shaft and located within the drum adjacent the juncture of the two diameters so as to divide the interior of the drum into two differently diametered chambers, grippers arranged on one side of the disc and within the small chamber for successively imparting an incipient and a quick rotation to the material, and other grippers secured to the other side of the disc and within the large chamber and extending across and partially into the small chamber for seizing the material and for facilitating the transfer of the material over the edge of the disc and mto the large chamber, substantlally as and for the purposes set forth.

2. Apparatus as claimed in claim 1, wherein the grippers in the large chan'iber are fitted to the drum at a predetermined angle to avoid the clogging of the material and sharp pointed attachments fitted on the ends of said grippers and disposed at angles to the main portion of the said grippers so as to extend across the periphery of the disc.

In testimony whereof I have signed my name to this specification.
