We, BOLD LUKE FLETCHER, Dyer and Finisher, and JOHN HOYLE Worsted
Spinner, both of 41 Crown Street, Halifax, in the County of York do hereby
declare the nature of this invention to be as follows:-
•
This invention has reference to apparatus for which a Patent was granted to
John William Lodge, dated the 1st day of June 1889, No. 9087, for ""An improved
process and means to be employed for partially destroying and mixing' night soil
and other refuse, and for converting the same into manure suitable for grass' land
and arable purposes," the invention in which case comprised new apparatus for
utilizing town's refuse. The present invention consists in combining with the
machinery set forth in Lodge's Specification an additional apparatus for receiving
the products of such machine and drying them for use as manure. Our improved
apparatus consists of a vertical tubular casing composed of metal or 'brickwork,
and within which are a series of 10 or other suitable number of hollow trays or
plates, placed one above another and heated by steam or other heating medium.
In the centre of the tubular casing is a vertical shaft, carrying two or other
number of blades or wings for each tray within the said casing, to which blades
are fixed a number of guide plates, made to revolve and traverse upon each plate.
The product issuing from Lodge's machinery, which product is in a plastic or
moist condition, is raised by an elevator into the top of the casing, and descends
upon the top hollow plate contained therein, such material being spread or distributed
upon the upper hot. plate, and pushed over the sides or edges thereof by the scrapers,
afterwards dropping therefrom onto the heated plate underneath, where the scrapers
or distributors on that plate cause the material to be scraped towards the centre
of the said plate, which is made with an opening through which it falls onto the
plate underneath it, the revolving scrapers of which said plate distribute' it and
cause it to fall over the outer edge of the plate, as in the preceding case, and this
goes on alternately, first over the outer edges and then within an opening 'of the
next succeeding plate,.and on reaching the bottom of the casing 'it is received by a
revolving worm or other equivalent device, and in turn taken by an elevator to a
separator, and caused to pass over a mesh or grate in a dry and finely powdered
condition ready to be used as artificial manure; but such of the material as is too
large to pass through the mesh of the sieve or grate is removed therefrom and
pulverised.

Our invention is also applicable for drying grain, minerals, and other substances
or materials.

We, BOLD LUKE FLETCHER, Dyer and Finisher, and JOHN HOYLE, Worsted
Spinner, both of 41- Crown Street, Halifax, in the County of York, do hereby
declare the nature of this invention and in what manner the same is to be
Peine RdI

page_text: performed, to be particularly described and ascertained in and by the following
statement:-
This invention has reference to a new means or method and apparatus for
treating and drying artificial manure, which is effected by being distributed and
spread by means of revolving scrapers over hot plates. The materials or substances
which we make and manufacture into manure, are composed of town's refuse,
including night soil and the like, and previous to such materials entering our new
or improved treating and drying machine, it is first of all broken, ground, and
mixed in an ordinary form of mortar mill or grinding pan. In our Provisional
Specification we stated that the materials had to be treated by a machine as
patented by John William Lodge No. 908789, but for our purpose we find the use
of that machine to be unnecessary, it being sufficient to use a mortar mill or other
grinding pan.
Such being the nature and object of our invention, we will now proceed to
describe the same more fully and for that purpose make reference to the accom-
panying sheet of drawings wherein
Fig. 1 is a vertical elevation, partly in section, of our improved apparatus and
Fig. 2 is cross-section of same taken through line A, B, of Fig. 1.
Our improved apparatus consists of a vertical tubular casing C composed of
metal, brickwork or other suitable material within which are a series of hollow
metal trays or plates D placed one above another and heated by steam or other
heating media, which is conveyed thereto by pipe E. In the centre of the tubular
casing C is a vertical revolving shaft F upon which is mounted two or other
number of blades or wings G to which are attached radial arms H carrying a
series of plates or scrapers I made to rotate or traverse upon the heated hollow
plates D. These scrapers are preferably composed of steel wires, but they may be
composed of bristles, card teeth, or other yielding material.. The product which is
in a plastic or moist condition is raised and placed upon the top hollow plate by
any suitable form of elevator where the said material is mixed and spread or
distributed upon the said hot plate by the scrapers I. These scrapers are placed
at such an angle as to draw the mixed materials towards the centre of the plate
and push it over the sides of an opening made in the centre of the said plate, so
that the material drops onto the heated plate underneath, where the scrapers or
distributors on that plate, cause the material to be scraped or to gravitate towards
the outer edge of the plate, which it will be seen on reference to the drawings
(see Fig. 1) that the plate second from the top, is less in diameter than the upper
plate, and this is done so that the material may drop over the outer edge onto the
plate underneath it; thus it will be seen that the revolving scrapers are so arranged
or inclined with respect to the axis of the vertical shaft F as to mix and draw the
material in one instance towards the centre of the plate, and in the other towards
the outer edge of the plate, and this goes on alternately first dropping within the
opening of the centre of one plate, then being worked outwardly and dropping
over the edge of the next succeeding plate, and so on until reaching the bottom of
the casing A where it is received by a revolving worm J or other equivalent device,
and in turn taken by another elevator to a suitable form of separator where it is
sieved and delivered in a dry and finely powdered condition ready to be used as
natural artificial manure, but such of the material as is too large to pass through
the mesh of the sieve or grate is removed therefrom and pulverized.
Although we do not limit ourselves to any particular form of separator, yet we
find that the particular form of apparatus shewn and described in Letters Patent
granted to Mumford and Moodie on the 12th of June 1888 No. 8643 answers our
purpose very well.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
-
....
Firstly. For treating and drying manure, the construction of apparatus, com-

page_text: prising heated hollow plates, in combination with revolving scrapers, all arranged
and operated substantially as herein described and shewn in the drawings.
Secondly. In a machine for treating or drying artificial manure, the use of
scrapers or distributors composed of bristles, wire or other yielding material.
Thirdly. For treating and drying manure, the construction and arrangement of
heated plates of different diameters, one set of plates having central openings
through which the material drops, whilst the other set of plates are so arranged as
to permit the material to drop over the outer edges thereof all as described.
