New Theater of Machines

...is driven by the lantern pinion original: "Trillis", it can be made of good solid wood, almost in the same shape as iron spice mills, and can be encased with iron ribs K; the lower body I should be prepared in the same way. It would also be good if one could adjust the cranked rod G together with the lantern pinion C upwards and downwards, so that one could grind coarsely or finely as needed, which the handle in the mechanism itself will demonstrate. For assistance and facilitation of the drive, a flywheel F is placed on top of the squared rod G; it could be made of stone, but it is better if made of wood with lead poured into its rim, or another flywheel could be arranged in its place. D is the rod for the movement of the bolter E.

Note: Such hand mills are also made of brass or iron, large or small, and experience will teach everyone which ones might be more advantageous and suitable.

The VIII. Figure.

Of a Hand Mill.

This is a type of hand mill which is drawn without a cogwheel original: "Kam-Rad" by a cranked handle A through the rods F, and thus the millstone E is driven around by the inserted iron A. For better help and ease of turning, the flywheel B is arranged with three attached weight stones FFF, and these three weight stones should be hung at the corners of an equilateral triangle, whose three points GGG are each hung at an equal distance from the beam H.

Note: The rod or upright axle tree H should go down at I onto a hardened point in a steel or brass bowl. It will be left to the artist's discretion to mount such rods at the bottom as desired. C.D. is for the movement of the bolter, but it should not be wrapped around at H,

nor attached firmly, and the stick I should strike loosely at D.

The IX. Figure.

Of a Hand Mill.

This is a type of hand mill which is almost the same as the previous one, only that it has a cogwheel A with a lantern pinion B, but at the bottom, it has a low flywheel D and a cranked rod E. The movement of the bolter can be seen in the figure at C.

The X. Figure.

Of a Larger Hand Mill.

The present hand mill is driven by two persons using the two rods C.D. that grasp the cranked rod B. The two rods are movably attached at E E on a solid, lying beam, and the length of the same depends on the height of the persons moving it, which rods should generally be five to six feet long. At A, one can once again arrange a wheel with lead poured into the rim for better momentum and easier labor. The pivot F should, as mentioned above, go from iron into a brass bowl.

Note: Where one has spelt or other such fruits to peel or pound, one can set up a round block H, which should be shod with iron at the bottom at K, with a treadle beam I, and have one peel the fruit in the hollow tree, which is shaped like a mortar, as is known, so it is unnecessary to make further ado about it.

The XI. Figure.

Of a Hand Mill.

This type of hand mill is somewhat more extensive and more expensive than the previous one, for it has first two flywheels A and B, and also two lantern pinions C and D.
