PROVISIONAL SPECIFICATION left by the said William Robert Lake at
the Office of the Commissioners of Patents on the 10th February 1877.

Southampton Buildings, London. "AN IMPROVED MACHINE FOR BRUISING,
BREAKING, GRINDING, DECORTICATING, AND PULVERIZING GRAIN, SEED, FIBROUS
MATERIALS, AND THE LIKE, FOR RASPING AND PLANING WOOD AND OTHER SUB-
STANCES, AND FOR OTHER LIKE PURPOSES." A communication from abroad by
Pierre Charles Désiré Destas, of Paris, France.
This Invention relates to a novel circular machine for bruising, breaking,
grinding, pulverizing, chopping, pounding, and decorticating various substances, such
as grain, seed, beets, textile material and the like, and for rasping and planing wood
and other materials, and for other like purposes.
This machine is composed essentially of a cylinder or drum whose circumference
is furnished with teeth or hooks. These teeth or hooks are held on the cylinder by
soldering, rivetting, screwing, or otherwise, and are arranged to form any desired
number of helicoidal circles or rings around the said cylinder. They are so inclined
upon the latter that all the teeth can act in succession one after the other upon the
materials to be bruised or otherwise treated.
The distance apart and inclination of these rings are so determined that the teeth
of one will not work in the same space as the teeth of the other rings. By this
arrangement all portions of the surface of the said cylinder or drum work one by
one, producing a considerable effect with a slight motive force.

page_text: The drum or cylinder, according to the nature of the material to be treated
therein, may be vertical, horizontal, or inclined. The hopper for the reception of
the materials to be reduced will be placed at the upper part or at the side of the
machine as may be found most convenient.
In order that my said Invention may be fully understood, I have in the accom-
panying Drawing shown, as an example only, a machine constructed according to
the said Invention.
Figure 1 is a longitudinal section of the said machine. Figure 2 is an end
elevation partly in section of the same.

cylinder or drum c; d, d, are plummer blocks for supporting the said shaft; e is a
cover of cast iron or other suitable material surrounding the cylinder c; f is the
hopper arranged at the upper part of the said machine; g is an inclined plane for
the escape of the pulverized or reduced material. The dotted lines in Figure 2
show the hopper arranged at the side of the machine; h, h, are the rings or circles
composed of teeth or hooks, whose number and dimensions are regulated according
to the material to be treated. These rings h are so inclined that all the teeth of
each ring work one after the other, and upon a surface corresponding with the angle
of inclination. The space between the toothed rings or circles is such that while
the circle 1 is grinding, chopping, or triturating the material upon the width from 2
to 3, the one marked works from 3 to 5, and all the other toothed circles or rings
act thus in succession; i, i, are fast and loose pulleys for controlling the said
machine.
When this machine is employed for planing, a plate is arranged below it for
receiving the wood planks or other materials to be planed; the teeth or hooks of
the drum will then act upon the upper side of the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Robert Lake in the Great Seal Patent Office on the 9th
August 1877.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED MACHINE FOR BRUISING,
BREAKING, GRINDING, DECORTICATING, AND PULVERIZING GRAIN, SEED, FIBROUS
MATERIALS, AND THE LIKE, FOR RASPING AND PLANING WOOD AND OTHER SUB-
STANCES, AND FOR OTHER LIKE PURPOSES." A communication from abroad by
Pierre Charles Désiré Destas, of Paris, France.
This Invention relates to a novel circular machine for bruising; breaking,
grinding, pulverizing, chopping, pounding, and decorticating various substances, such
as grain, seed, beets, textile materials and the like, and for rasping and planing
wood and other materials, and for similar purposes.
This machine is composed essentially of a cylinder or drum whose circumference
is furnished with teeth or hooks. These teeth or hooks are held on the cylinder by
soldering, rivetting, screwing, or otherwise, and are arranged to form any desired
number of helicoidal circles or rings around the said cylinder. They are so inclined
upon the latter that all the teeth can act in succession one after the other upon the
materials to be bruised, cut, or otherwise treated.
The distance apart and inclination of these rings are so determined that the teeth
of one will not work in the same space or through the same path as the teeth of the
other rings. By this arrangement all portions of the surface of the said cylinder
or drum work one by one, that is to say, each part performs its own work, thus pro-
ducing a considerable effect with a slight motive force..
The drum or cylinder, according to the nature of the material to be bruised,

page_text: | broken, rasped, or otherwise treated thereby may be vertical, horizontal, or inclined.
The hopper for the reception of the material to be reduced will be placed at the
upper part or at the side of the machine, as may be found most convenient.
In order that my said Invention may be fully understood, I have in the accom-
panying Drawing shown, as an example only, a machine constructed according to
the said Invention.
Figure 1 is a longitudinal section of the said machine; Figure 2 is an end eleva-
tion partly in section of the same.
Like letters indicate the same parts in both of these Figures.
a is the frame of the said machine; b is the shaft upon which is mounted the
cylinder or drum c; d, d, are plummer blocks for supporting the said shaft; e is a
cover of cast iron or other suitable material surrounding the cylinder c; f is the
hopper arranged at the upper part of the said machine; g is an inclined plane for
the escape of the pulverized or reduced material. The dotted lines in Figure 2
show the hopper arranged at the side of the machine; h, h, aro the rings or circles
composed of teeth or hooks, whose number and dimensions are regulated according
to the material to be treated. These rings h are so inclined that all the teeth of
each ring work one after the other and upon a surface corresponding with the angle
of inclination. The space between the toothed rings or circles is such that while
the circle 1 is grinding, chopping, or triturating the material upon the width from
2 to 3, the one marked 4 works from 3 to 5, and all the other toothed circles or
rings act thus in succession; i, i, are fast and loose pulleys for controlling the said
machine.
When this machine is employed for planing, a plate is arranged below it for
receiving the wood planks or other materials to be planed; the teeth or hooks of
the drum will then act at the lower side of the same.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent and the manner of performing the same, I wish it understood
that I claim, the machine for pounding, crushing, cutting, bruising, grinding,
decorticating, rasping, planing, and for other like purposes, constructed with a
cylinder or drum whereon are fixed circular series of rings of teeth or hooks, which
operate successively upon the matters to be treated, and which machine may occupy
a vertical, horizontal, or other suitable position, as above set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Ninth day of August, in the year of our Lord One
thousand eight hundred and seventy-seven.
