thus mix and divide it more perfectly. No
blades or projections are affixed to the interior of the cylinder.
Above, where the peat enters into a flaring hopper, is a scraper, that
prevents adhesion to the sides and gives downward propulsion to the
peat. The blades are, by this construction, very strong, and not liable
to injury from small stones or roots, and effectually reduce the
toughest and most compact peat.
Furthermore, addition of water is not only unnecessary in any case, but
the peat may be advantageously air-dried to a considerable extent before
it enters the machine. Wet peat is, indeed, worked with less expenditure
of power; but the moulded peats are then so soft as to require much care
in the handling, and must be spread out in single courses, as they will
not bear to be placed one upon another. Peat, that is somewhat dry,
though requiring more power to work, leaves the machine in blocks that
can be piled up on edge and upon each other, six or eight high, without
difficulty, and require, of course, less time for curing.
The cut, (fig. 18), represents one of Schlickeysen's portable
peat-mills, with elevator for feeding, from which an idea of the
pulverizing arrangements may be gathered.
In Livonia, near Pernan, according to Leo, two of Schlickeysen's
machines, No. 6, were put in operation upon a purely fibrous peat. They
were driven by an engine of 12 horse-power. The peat was plowed, once
harrowed, then carted directly to the hopper of the machine. These two
machines, with 26 men and 4 horses, produced daily 60,000 peats = 7500
cubic feet. 100 cubic feet of these peats were equal in heating effect
to 130 cubic feet of fir-wood, and cost but two-thirds as much. The
peats were extremely hard, and dried in a few days sufficiently for use.
In 1864, five large Schlickeysen machines were in operation at one
establishment at St. Miskolz, in Hungary.
The smaller sizes of Schlickeysen's machine are easily-portable, and
adapted for horse or hand-power.
_Leavitt's Peat-condensing and Moulding Mill._[27]--In this country, Mr.
T. H. Leavitt, of Boston, has patented machinery, which is in operation
at East Lexington, Mass., at the works of the Boston Peat Company. The
process is essentially identical with that of Weber, the hot-drying
omitted. The fresh peat is pulverized or cut fine, moulded into blocks,
and dried on light frames in the open air. The results claimed by Mr.
Leavitt, indicate, that his machine
