The water wheel I engages with the spindles attached to the shaft into the cogs or upward-standing pins of the horizontally lying wheel O, which further rotates the trillis L together with the millstone A. Thus, it needs no further description. Only it is to be known here that one must properly proportion the size, or circumference, of the horizontal wheel O and align its teeth correctly against the spindles at D, and thereby carry out the rotation not too quickly or too slowly. The proportion of such division and description is, for special variable reasons, diligently omitted and passed over not only in these figures but in all others, so there is no need to make further prolixity of it.
This mill has two horizontal water wheels of two types, B and D. They can be usefully arranged by the artist at will and according to the local circumstances, provided that one has both water boxes F and G, together with the waterfalls M and L. The water is led from the boxes F and G through the canals A and E, and the drainage of the water is led away under the wheels according to the location. Both millstones I and K are driven by C and H; they can be inserted there with bolts, and raised and lowered.
This mill has one water wheel B, which is driven by a waterfall from above, according to the local circumstances. On the shaft F, the wheel C, toothed on the side, is arranged, which engages with its teeth into the spindles D, and thereby rotates the upright-standing shaft I together with the millstone G, as well as causing the movement of the bolter H through the stick at E.
This mill is almost entirely the same in its drive as the previous one. The only difference here is that where one cannot have a natural fall of water, one arranges a double or single pressure mechanism a pump system, as one sees with the two boots cylinders/bellows G and H, through which the water is then driven through I into the canal A, and thereby rotates the wheel B, together with the remaining C, D, E, F, G.
Note: It is to be noted here that one must initially rotate the wheel through another drive for as long as it has no waterfall, until it drives the necessary water through the pressure mechanism into the height, and thus the water wheel itself is brought into motion. For the inventor of this work believes in raising the falling water again and again through the pressure mechanism and continuing this for as long as one can have water. Doing the test in the construction itself will show how long this motion might last.
This mill is to be arranged at a river in flat land, where one cannot have a waterfall from above. It has an undershot water wheel E, which through its shaft D rotates the side-toothed wheel T, together with its trillis I and the millstone H. Through the lever A with the attached weight B, the millstone can be raised and lowered, depending on whether one wants the flour, or whatever one wants to grind, coarse or fine.
