Application January 10, 1936, Serial No. 58,444
8 Claims. (Cl. 193-2)
This invention relates to material distributing
apparatus, and more particularly to apparatus
for distributing granular or powderous materials
among aplurality of feeding devices.
IN5_
One object of the present inventionA is to provide
generally improved distributing apparatus for
granular or pulverulent materials.
'
Another object is to provide improved appara
tus for evenly distributing fuel, such as coal, coke,
iz) and cinders, among a series of stoker feeding
devices so that the -fuel fed to the furnace Will
be substantially uniform throughout.
Another object is to provide improved material
chutes having compartments therein for receiving
materials of different kinds, the chutes being so
constructed as to evenly distribute materials
v’among a series of receiving devices.
Other and further objects will become appar
ent as the description of the invention progresses.

.
latter may receive cinders or powderous fuel from
spouts I5, as will appear more fully'hereinafter.
Fig. 2 shows a ram 6 in its advanced position.
Upon recession thereof, after a feeding operation,
the fuel in compartment I3 will, first gravitate
into the cylinder l, after which fuel from com
partment I2 will enter said cylinder. As the ram
is then actuated in the 4feeding direction the
heavier materials gravitating in the cylinder from
compartment I2 will be pushed over the lighter
materials, as shown in Fig. 2. The lighter fuel,
being thus covered by a layer of heavier fuel, will
not be blown from the grates by the draft air,
and as a result complete combustion of all of
the fuel fed to the furnace is assured. Chutes I4
may be of the conical type shown and described
in United States Patent No. 1,947,011, and each
receives fuel from overhead bunkers (not shown)
through a spout I6. By this construction the
large and small particles of fuel gravitating into 20

nately disposed retorts 3 and tuyère rows 4. Fuel
is supplied to the stoker 2 from a hopper 5 dis
posed near the front end thereof, and a series
of rams 5 operating in cylinders ‘I feed prede
ment E3 of hopper 5 in such a manner that each 45
ram 6 will feed an equal quantity of cinders or
powderous fuel upon each reciprocation' thereof.
'Inasmuch as the chutes I4 communicating with
underfeed the fuel in the retorts in a well known
manner. The rams 6 and pushers 8 are oper
ated by‘any suitable power mechanism 9, they
being operatively connected thereto by a link and
lever mechanism indicated generally by the nu
meral li). Hopper 5 is provided with a partition
I E which divides the space therein in_to two com
partments I2 and I3, the former of which may
60 receive coal or coke from a chute I4, while the
35
thereof enter the upper end of compartment I3
directly over the cylinders 'I. By this arrange 40
ment, it is seen that the fuel gravitating into
chamber I'I is evenly kdistributed therein, vand as
a result equal quantities of fuel will enter each
of the spouts I5 and be discharged into compart
cation thereof.

compartments I2 also evenly distribute the heav
ier and lighter particles of fuel, among the cyl 50
inders 'l _associated therewith, the fuel fed to
each section of the stoker will be substantially
uniform throughout.
'
Figs. 5 to 9 inclusive show an alternative con
struction for distributing materials of different
kinds among each of a series of feeding devices.
This construction comprises a chute 22 having
downwardly inclined, substantially conical top
and bottom Walls 23 and 24 respectively, and 60

2,133,798
downwardly diverging side walls 25. A substan
tially conical partition 26 is mounted between top
and bottom walls 23 and 24 dividing the interior
of chute 22 into compartments 21 and 28, the
former of which may, in the present instance,
receive cylinders or powderous fuel, while the
latter, coal or coke. Top and bottom walls 23
and 24, and partition 26 terminate at the-lower
ends thereof in vertical extensions 29, _30 _and 3|
respectively, forming with the end walls 32 ver
tical discharge passages 33 and 34 for compart
ments 21 and 28. Substantially cylindrical eX
tensions 35 and 36 are secured to the upper end of
chute 22 in any suitable manner, forming inlet
passages to compartments 21 and 28 respectively.
The discharge passages 33 and 34 of chute 22
communicate respectively with the compartments
31 and 38 of a hopper 39.
The fuel supplied to
hopper 39 gravitates into cylinders 40, and is fed
to the furnace by the rams 4I operating therein,
as previously described.
rI_lhe top and bottom walls 23 and 24, as well as
partition 26 incline downwardly at an angle some
what greater than the angle of repose, and by
virtiie1 of the conical construction thereof the
materials gravit'ating in'compartments 21 and 28
will be evenly distributed across the entire dis
charge end of the chute.
