JOHANN KUBON in DRESDEN. Innovations in the combination of a pointed course with a grain peeling machine.

Patent addition to No. 2204 of February 17, 1878.

Patented in the German Empire on June 19, 1879. Longest duration: February 16, 1893.

The drawings show:

Fig. Ι the basic outline,

Fig. 2 shows the average and

3 shows a horizontal section through the screw D,

Fig. 4 shows the average and

5 shows the basic pattern for a different stone setting mechanism,

6 shows a vertical section along line 2-2 of FIG. 1,

7 shows a section along line 5-5 in FIG. 6, FIG. 8 shows a section along line 6-6 in FIG. 6.

The general arrangement and operation of those illustrated in FIGS. 1-6 Machine does not differ significantly from that explained in the description of the main patents and the only difference is a different arrangement, as well as the addition of individual ones Parts.

The grain, after it has been freed from the coarser impurities and fine weed seeds etc., on a sieve device, is passed through the inlet W provided with distribution studs into the separation apparatus A and here the effect of the suction generated by the exhaustor Q Exposed to air flow. The light grains and dust particles are taken up by the air stream in the three channels h , while the heavy grains fall into the screw trough C. The light grains get into space e and collect on flap m (see also FIGS. 7 and 8) until it opens due to the increasing load and the material lets pass into space e ¹ , from where it then passes through Flap m 'is emptied. Between the alternating evacuation periods, the flaps are kept closed by the suction effect of the exhauster. After all the grains have emerged from the air stream, it drives the remaining dust and chaff parts through the channel t, the exhaustor and the pipe X into the open air.

The fallen into the screw trough C grains are supplied by the screw D, whose drive is it follows readily from FIG. 2 through the pipe L through the spigot passage FH, to be subjected here the well-known operation of the spitz or Koppens. With regard to this pointed passage, it should be noted that the lower stone H is fastened to the stone plate H ¹ connected to the main shaft E and accordingly rotates, while the upper non-rotating stone F can be positioned. The same is bolted to the end of a plate F ', Fig. 2, whose inner rim is provided internally with screw thread I ^1, which corresponds to the thread of the äuferen mounted in the top plate M L tube. The gear wheel d is united with the disk ^ ¹ , which is moved by the handwheel <: 'by means of the conical wheels c and b and the spur gear α . The wheel b sits loosely on the axis /, but takes the latter with it by a spring, so that the weight α wedged onto / can sink down and remain in engagement with the wheel d when the plate F ^{1 is} screwed down. That by means of this facility a higher or higher Lowering the stone F can be effected does not require further explanation; It must be emphasized, however, that the rotation necessarily connected with the displacement of the stone F offers the advantage that the stones can never "wedge" one another, that is, wear at an angle or unevenly. The handwheel c ¹ must always be attached by a pin or in some other way after the setting has been made, since the runner tries to take the upper stone with him and thus to adjust it. Incidentally, any other suitable mechanism can also be used to rotate the plate F ^1.

4 and 5 show a stone position which corresponds in principle to that explained in the main patent, but shows a modified arrangement appropriate to the circumstances. The stone plate F ¹ hangs on four adjusting screws a ² , the nuts of which are formed by the gears α and α ^l , which run on lugs that are cast on the cover plate M , and are in engagement with the wheel d. The wheel a

is cast together with the conical wheel, and this is moved by gear c from the handwheel <sl. In this case, turning the handwheel causes the stone to be adjusted vertically, but without turning it. The further processing of the grain takes place on the peeling device located below the Spitzgang. The final sorting of the grains and the admixtures still present is carried out by the separation apparatus B, which in and of itself has no new peculiarities, but a regulator is combined with it (see Figs. 1 and 6). This opens the holes x \ by means of a slide χ in case the machine runs too fast. Air then enters through the holes χ ', and the current of air, which otherwise would become excessively strong due to the exhaustor running too quickly and which would also ripen with good grains, is again moderated. Pat en τ claims: On the under P. R. No. 2204 patented Spitzgange the following innovations: 1. The device for adjusting the upper stone F, consisting of the stone plate F ¹ screwed onto the pipe L with a thread and a suitable gear transmission for rotating this plate. 2. In combination with the stationary Oberstein the adjusting screw <z ² , the wheels a, a ^l and d and a back gear used to move the wheel a. 3. The regulator W, which by means of a slide or flap opens and closes the openings x ^{1 of} the separation apparatus for the purpose of regulating the air flow. For this purpose I sheet drawings.
