PROVISIONAL SPECIFICATION.
Improvements in Apparatus used in the Manufacture of Sulphate of
Ammonia.
I, CHARLES MARRIOTT of No. 2 German Street Redcar in the County of York
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to wint is teeny amount
ammonia salt is formed & consists in improved means whereby the salt is con-
tinuously fished" or removed by selfacting means.
"
I make the body of the saturator by preference of the following shape. A vertical
or nearly vertical back, a radial bottom, an inclined front, & of any suitable
width & depth & place over the centre of the radial bottom, the bell in
which the waste gases collect, & through the centre of the bell in a vertical
position, I place the ammonical gas or saturator pipe terminating at the bottom
in a perforated tee pipe, the bottom or tee end being a short distance above
the bottom of the vessel & immediately over the radial part of the same a space
being left between the outside of the bell & the vertical or nearly vertical back of
the vessel.
At the back of the vessel or saturator I place three or more driving or drawing
rollers, & underneath & outside the vessel a carrying roller, & in front of the
apparatus in line with the inclined front & at any convenient distance away
another carrying roller, all the said rollers working in bearings in the framework.
Over the said rollers I place an endless apron the full width of the vessel made
of wire gauze, & of a suitable mesh, the said apron being of such length, that it
passes over & under the driving or drawing rollers, down the vertical or nearly
vertical back, along the radial bottom, under the tee pipe & bell, up the inclined
front, over the roller at the top & back under the roller underneath the bottom,
& again to the driving or drawing rollers.
The action of the apparatus is as follows.
The saturator being charged with acid to a suitable depth & the ammonical gas
being put in communication, as the salt is formed it is deposited on the apron, which
has a slow travelling motion imparted to it by means of the drawing rollers, & thus
the salt is continuously removed out of the vessel up the inclined front, in its
passage being drained of any surplus liquor, which drains back into the saturator.
Underneath the roller at the top of the inclined front & in contact with the
endless apron, 1 place a stationary knife or scraper to remove the salt from it, or
a revolving brush may be used for the same purpose & thus the salt is continuously
& evenly fished or removed, drained & evenly deposited in a perfectly selfacting
manner in any suitable place.
I do not confine myself to the use of an endles apron, made of wire gauze as a
travelling lattice with suitable openings for drainage, may be used for the same
purpose, the driving or drawing rollers being arranged to suit.
Dated this 16th day of March 1891.

I CHARLES MARRIOTT Westbourne Grove Redear in the County of York,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to what is technically known as the "saturator in which
the ammonia salt is formed and consists in improved menus whereby the salt is
continuously "fished or removed by self acting means.
These improvements will be clearly understood by reference to the accompanying
sheet of drawing and to the letters of reference marked thereon
Fig. 1 being a longitudinal and Fig. 2 a transverse section of the improved
saturator the letters of reference referring to similar parts.
I make the body of the saturator by preference of the shape shewn on the drawing
riz. a vertical or nearly vertical back a radial bottom 6 an inclined front d and of
any suitable width and depth and place over the radial bottom 6 the bell e in which
the waste gases collect.
Through the centre of the bell in a vertical position I place the aminonical gas
or saturator pipe terminating at the bottom in a perforated tee pipe the tee
end being a short distance above the bottom of the vessel and immediately over the
radial part
a space being left between the outside of the bell e and the vertical
or nearly vertical back of the vessel.
At the back of the saturator I place three or more driving or drawing rollers i j k
and underneath and outside the vessel a carrying roller and in front of the
apparatus in line with the inclined front and at any convenient distance another
carrying roller m and at suitable distances apart down the inclined part other
small rollers all the said rollers working in bearings in the framework.
Over the said rollers 1 place an endless apron o the full width of the inside of
the vessel, the said apron being made of wire gauze of a suitable mesh, the apron
being of such length that it passes over and under the driving or drawing rollers i j k
down the vertical or nearly vertical back a along the radial bottom under the
tee pipe and bell e up the inclined front d and over the roller m at the top and
back under the roller underneath the vessel and again to the driving or drawing
rollers i j k the said rollers being driven from any convenient source & thus give the
apron a travelling motion.
The action of the apparatus is as follows.
The saturator being charged with acid to a suitable depth and the ammonical gas
being put in communication the salt as it is formed is deposited on the travelling
apron and is continuously carried on it or "fished "out of the vessel up the inclined
front, in its passage being drained of any surplus liquor which drains back into
the saturator, the acid being kept at one constant level by any well known means.
Underneath the roller at the top of the inclined front and in contact or nearly
so with the endless apron 1 place a stationary knife or scraper p to remove the salt
from it, to fall into any convenient place, or I use a stationary or revolving brush
when desired for the same purpose.
It will thus be seen that the salt is continuously and evenly "fished," drained,
and evenly deposited in a perfectly self acting manner.
I do not confine myself to the use of an endless apron made of wire gauze, as
a travelling lattice may be used for the same purpose, the lattice having suitable
openings for draining the driving rollers or gearing being arranged to suit, the
speed or travel of the apron being arranged to suit the thickness of salt deposited
on it as desired.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1st. The improved saturator having an opening or space between the bell and
the back of the vessel.
2nd. The employment of an endless travelling apron delivered into saturator at
the back and under the tee or saturator pipe and bell and out at the front as
herein described and illustrated on the accompanying sheet of drawings or any mere
modification thereof.
