Improvements in Means for Feeding and Disintegrating Clay.
I, ARTHUR EDWARD NICHOLL of Streatham Rectory, Streatham, London, S.W.,
A.M.I.C.E., do hereby declare the nature of this invention to be as follows:-
To feed clay to the revolving pan of a grinding machine I provide the feed chute
with a rotary wheel or device consisting of radial partitions forming between them
compartiments into which the clay falls from the chute, and I cause the rotation of
this wheel or device to be effected from the axle of the grinding machine or to be
controlled or governed therefrom or otherwise according to the revolution of the pan
so as to permit the compartments to be discharged successively into the pan at a rate
dependent on the rate of revolution of the pan. When the weight of the charges
of clay in the compartiments is sufficient to turn this wheel or device the latter may
be periodically arrested by stops or the like on or controlled by or according to the
revolution of the pan.
To disintegrate the clay in a machine having a revolving pan, for instance in one
provided with a running surface on which edge runners work and with a grating or
the like through which the comminuted clay is to pass, it is desirable to spray the
clay so that it will fall through the grating and not choke the same, and for this
purpose I use a disentegrator composed of a bar or holder having a series of teeth of
such form that they will cut into and spray upward behind them or to the one or
other side of the clay, for instance a bed of clay adhering more or less to the
revolving pan or its grating. Such teeth inay be in the form of plates bent to
constitute helicoidal knives the edges of which cut into the clay, and also bent so as
to form a scraper to the gratings or the like.
To facilitate the action it may be desirable to cause some of the clay to form a
binding layer on the pan or grating by suitable means, and if desired the teeth may
be so placed on the disintegrators, two or more being used so that this layer of clay
is cut into by some teeth so as to spray therefrom strips, leaving other strips to be
partly removed by the other disintegrator since this facilitates also the spraying
action, and some teeth to scrape the gratings or the like, acting as scrapers. I also
may have the scrapers made with openings either at the top or side or under so as to
allow the clay to go through, over or under it, allowing it to revolve with the pan so
as to prevent its going under the edge runners more than is necessary and in these
openings inay be put cutters of suitable form, so as to further break up the clay.
I inay also have a small feed channel or hole led into the pan, with or without a
revolving feeder as above, so as to feed into the pan burnt or dried clay ground to
powder, or other material, to facilitate passage of the clay, or to improve the bricks
or for other reason. I may also put the toothed scrapers underneath pan to keep it.

I, ARTHUR EDWARD NICHOLL, of Streatham Rectory, Streathamn, London, S.W.
A.M.I.C.E. 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 means for feeding and disintegrating clay.
In the annexed drawing are shown diagrammatic views which with the assistance
of the following description will sufficiently indicate the nature of this invention and
how it is to be performed.
Fig. 1 is a diagrammatic vertical section and Fig. 2 a plan showing this invention
applying to a rotary pan.
To feed clay to a revolving or other pan A of a grinding machine as in
Figs. 1 and 2, I provide the feed chute B with a rotary wheel C or device consisting
of radial partitions forming between them compartments into which the clay falls
from the chute B.
I cause by any suitable gear the rotation of this wheel or device to be effected from
the axle of the grinding machine or to be controlled or governed therefrom or
otherwise according to the revolution of the pan so that the rate of discharge of the
compartments into the pan is dependent on the rate of revolution of the pan. When
the weight of this charge of clay in the compartments is sufficient to turn the wheel
or device the latter may be periodically arrested by stops or the like on or controlled
by or according to the revolution of the pan in a inanner that will be readily
understood.
To disintegrate the clay in a machine having a revolving pan A for instance in one
provided with a running surface on which edge runners D work and with a grating or
the like E through which the comminuted clay is to pass, it is desirable to spray the
clay so that it will fall through the grating and not choke the same and for this
purpose I use a disintegrator composed of a bar or holder Y fixed on uprights Y¹ and
having a series of teeth serrated or plain of such form that they will cut the clay.
Such teeth may also be in the form of bent plates, or with teeth like the disintegrators
as shown at Z in Fig. 2.
Rotary disintegrators F are shown in Figs. 1 and 2. On the shafts a suitably
driven by any gear are keyed spiders the peripheries of which carry lugs to which
the plates or teeth d are bolted. If desired the plates or teeth d may be secured
directly on the shafts a. These plates or teeth may be parallel to the shafts or
placed helicoidally as illustrated and they may stand radially as illustrated or
obliquely.
The plates d may be straight edged as illustrated or serrated as at Z Fig. 2. Since
to facilitate the action it may be desirable to cause some of the clay to form a binding
layer on the pan or grating by suitable means, for instance the pressure of the edge
runners D; if desired the teeth of the plates may be so placed on the disintegrators
two or more being used that this layer of clay is cut into by some teeth so as to cut
therefrom strips, leaving other strips to be partly removed by the other disintegrator
since this facilitates also the cutting action and some teeth to scrape the gratings or
the like, acting as scrapers. I also have the plates or scrapers made with openings
as at X either at the top or side or under so as to allow the clay to go through, or
under them allowing the disintegrators to revolve with the pan so as to prevent the
clay going under the edge runners more than is necessary and in these openings may
be put cutters of suitable form so as to further break up the clay. I inay also have
a sinall feed channel B or hole led into the pan or receptacle with or without a

page_text: revolving feeder as above, so as to feed into the pan or receptacle burnt or dried clay
ground to powder or other material to facilitate passage of the clay or to improve the
bricks or for other reason. I may also put toothed scrapers underneath the pan to
keep it clear.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. The feed device comprising the hopper with rotary compartment wheel driven
in proportion to the speed of the revolving pan, or formed to feed and deliver the
clay in the manner substantially as described.
2. The disintegrator constructed substantially as herein described and adapted to
cut up the clay.
3. The construction of feed device and disintegrator substantially as herein
described for the purpose of preparing clay in the manner set forth.
Dated this 9th day of August 1897.
