Iμ- PROVEMENTS IN MACHINERY OR APPARATUS FOR DISINTEGRATING OR PULVERIZING
Year: 1875

page_text: LETTERS PATENT to Michael Pass, Lime Burner, and Michael Dallett
Pass, Engineer, both of Plymouth Wharf, Isle of Dogs, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN
PROVISIONAL SPECIFICATION left by the said Michael Pass and'
Michael Dallett Pass at the Office of the Commissioners of Patents,
with their Petition, on the 13th September 1875.
We, MICHAEL PASS, Lime Burner, and MICHAEL DALLETT PASS,
Engineer, both of Plymouth Wharf, Isle of Dogs, in the County of
Middlesex, do hereby declare the nature of our said Invention for “Iμ-
PROVEMENTS IN MACHINERY OR APPARATUS FOR DISINTEGRATING OR PULVERIZING,”
to be as follows :—
Our Invention relates to machinery or apparatus intended more
particularly to be employed for disintegrating or pulverizing whiting or
ingredients used in the manufacture of artificial manure, but which is
also applicable for effecting the reduction or comminution of other
substances, and it consists of a peculiar arrangement and combination

page_text: of apparatus, whereby those operations are performed with greater
rapidity and more economically than with the apparatus heretofore
adopted.
In carrying out our Invention we introduce the material to be dis-
integrated or pulverized into a hopper, having a revolving screw mounted
therein transversely or otherwise, and which is driven by means of a
belt and pullies or in any other suitable manner from the driving shaft
of the machine: This screw is arranged in such a manner that the
material, by the act of passing the same whilst being fed into the
apparatus, is subjected to a preliminary disintegration, after which such
material descends into the interior of a cylindrical receptacle, having
revolving therein a square or other suitably shaped boss fitted with
projecting bars or arms, and mounted on the driving shaft of the
machine or on a shaft driven therefrom.
The bars or arms may be arranged in various ways, and either radially
or otherwise, but when a square boss is employed it is preferred to fit a
series of projecting bars to each side of such boss, so as to lie parallel
therewith, thus forming four series round the boss, the intervals or spaces
between one set of bars being opposite the bars of the next set. The
ends of the bars are by preference arranged nearly in contact with the
internal surface of the cylindrical receptacle, and the material as it
descends is projected from one set of bars to the other and between
the intervening spaces of the bars, and when sufficiently reduced is
discharged through an outlet aperture in the circumference of the
receptacle.

filed by the said Michael Pass and Michael Dallett Pass in the
Great Seal Patent Office on the 13th March 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MICHAEL
PASS, Lime Burner, and MICHAEL DALLETT PASS; Engineer, both of
Plymouth Wharf, Isle of Dogs, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, tho said Michael Pass and Michael
Dallett Pass, Her special licence that we, the said Michael Pass and
Michael Dallett Pass, our executors, administrators, and assigns, or
such others as we, the said Michael Pass and Michael Dallett Pass,
our executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain.
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DISINTEGRATING OR PUL-
VERIZING," upon the condition (amongst others) that we, the said
Michael Pass and Michael Dallett Pass, our executors or adminis-
trators, by an instrument in writing under our, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Michael Pass and Michael. Dallett
Pass, do hereby declare the nature of our said Invention, and in what
imanner the same is to be performed; to be particularly described and
ascertained in and by the following statement :-
Our Invention relates to machinery or apparatus intended more
particularly to be employed for disintegrating or pulverizing whiting or
ingredients used in. the manufacture of artificial manure, but which is

page_text: also applicable for effecting the reduction or comminution of other
substances, and it consists of a peculiar arrangement and combination
of apparatus, whereby those operations are intended to be performed
with greater rapidity and more economically than with the apparatus
heretofore adopted.
In carrying out our Invention we introduce the material to be dis-
integrated or pulverized into a hopper, having a revolving screw mounted
therein transversely or otherwise, and which is driven by means of a belt
and pulleys or in any other suitable manner from the driving shaft of the
machine. This screw is arranged in such a manner that the material,
by the act of passing the same whilst being fed into the apparatus, is
subjected to a preliminary disintegration, after which such material
descends into the interior of a cylindrical receptacle having revolving
therein a square or other suitably shaped block, box, or frame, fitted
with projecting bars or arms, and mounted on the driving shaft of
the machine or on a shaft driven therefrom.
The bars or arms may be arranged in various ways, and either radially
or otherwise, but when a square block, box, or frame is employed it is
preferred to fit a series of projecting bars to each side of such block, box,
or frame, so as to lie parallel therewith, thus forming four series round
the block, box, or frame, the intervals or spaces between one set of bars
being opposite the bars of the next set. The ends of the bars are by
preference arranged nearly in contact with the internal surface of the
cylindrical receptacle, and the material as it descends is projected from
one set of bars to the other and between the intervening spaces of the
bars, and when sufficiently reduced is discharged through an outlet
aperture in the circumference of the receptacle.
Doors are if desired provided at the sides of the receptacle, at the
-lower-portion thereof,-for-the-withdrawal of any stones or extraneous
substances which may enter the apparatus.
-It-is-preferred-to-make-one-side-of-the-hopper-adjustable-by-hinging-it-
to the body-and-providing a suitable regulating screw, by the act of
turning which the interval between the feeding screw and the adjustable
side of the hopper may be varied as required.

page_text: This mechanism is susceptible of being worked with very rapid
motion, and its successful use will be ensured by making the arms
revolve at a high rate of speed.
Having thus particularly described the nature and objects of our said
Invention, and incidentally intimated in what manner the same is to be
performed or carried out in practice, we will now, aided by the foregoing
statements and the statements hereafter set forth, particularly describe
and ascertain in what manner the same is to be performed or carried out
in practice by reference to the accompanying Drawings.

page_text: "Improvements in Machinery or Apparatus for Disintegrating or Pul-
verizing," substantially as the same are herein-before set forth and
described, wherein the adoption of a block, box, or frame with projecting
bars or arms is a novel and peculiar feature; it being understood that
we do not claim the mere details of construction shewn by the Drawings,
except as forming part of the said Invention; nor do we limit ourselves
to the use of such details, as same may be varied without departing from
the nature and character of the Invention, substantially as the same is
hercin-before set forth and described.
