irons. The stud bolts l8 each carry four nuts
l9 which engage the channel ?anges and angle
irons, so that by adjusting the position of the
nuts upon the stud bolts the angle irons l6 and
15 slides H can be adjusted as to height and an
gularity.
‘
1'
A pair of guide members are interposed be
tween the lower edges 29 of the sloping sides of
the hopper 5 and the top faces of the carrier
20 belt 9. These guide members consist of a pair
of angle irons 2| which are of greater length
than the hopper and extend from one end of
the hopper to engage the cover belt l3 as it
passes around the pulley 22 into contact with
26 the'lower belt.
The angle irons 2| are each so
positioned that one ?ange is horizontal and the
other ?ange vertical. The horizontal ?anges
engage the lower edges 20 of the sides of the
hopper and the vertical ?anges extend down
30 wardly from the edges of the hopper into close
proximity with the top of the belt 9. The bot
tom opening of the hopper and guide angle
irons 2| are so dimensioned and arranged that
the distance between the vertical ?anges of the
35 angle irons is substantially the same as the width
of the trough of the belt, so that material passing
from the hopper is directed into the trough and
does not contact the top faces of the belt.
The ends 23 of the hopper each carry a pair
40 of brackets 24 which engage the top faces of the
angle irons 2| and the angle irons are secured
to the brackets by bolts 25 which pass through
longitudinally extending slots 42 in the horizon
tal ?anges of the angle irons and ori?ces in the
45
brackets. By this arrangement, the loosening of
the bolts 25 permits the angle irons to be slid
forwardly or rearwardly as occasion demands.
In the forward ends of the angle irons the
horizontal ?anges are cut away and the ends
50 26 of the vertical ?anges are rounded with the
same curvature as the periphery of the cover belt
|3 passing around the pulley 22 so that such
forward rounded ends can be positioned in close
proximity to the faces 21 of the cover belt l3, as
55 illustrated in the broken away disclosure of the
provided with a plurality of circular partitions
3|, the pulley 39 is formed with a. peripheral
groove 32 to receive the partitions.v
-
As the material carrying portion of the belt 9
travelling between the end of the hopper and
the cover belt 3, after the belt has passed through
the hopper, is not covered by the cover belt, I
provide a semi-cylindrical metal cover 33 which
extends between the end of the hopper and the
curved belt l3. The forward end 34 of such 10
member 33 has’ a curvature corresponding to
the curvature of the outer faces of the cover belt
vl3 so that it is in close contact therewith-to pre
vent the possibility of ?ne material flu?ing out.
The forward and rear ends of the hopper are 15
provided with semi-circular ori?ces 35 and 36
through which the belt 9 and its partitions 3|
pass. The member 33 is of substantially the'same
internal diameter as they diameter of the parti
tions 3|, so that the partitions and the material 20
heaped therebetween can freely pass through
member . 33.
The member 33 is secured
upon a vertical plate 31 which is supported on
the front face of the end of the hopper by a
pair of bolts 38 which pass through vertical 25
slots 39 in the plate 31 and are threaded into
ori?ces 40 in the forward end of the hopper.
' such
By loosening the bolts 38 the plate 31 and mem
ber 33 can be adjusted in height to regulate the
heaping of the material in the belt 9 as it passes 30
from out of the‘ hopper.
The portion of the belt 9 between the pulley
30 and the rear end of the hopper is also covered
by a member 4| of similar shape to the member
33, and the pulley 30 is arranged at such a dis- '
tance from the end of the hopper, and the mem
ber ll of such a length, that as one partition 3|
enters the hopper, another partition has entered
the member 4|, as shown by two of the partitions
illustrated in dotted lines in Figure 1. By this 40
construction there is no possibility of powdery
material creeping back towards the pulley 30
through the member 4|. The member 33 is also
of such a length that as one partition 3| passes
from its outer end another partition 3| has
entered its inner'end. The pulleys 22 and 39
are suitably supported and are, of course, sub
stantially in alignment with the hopper as
sembly.
\
When a conveyer incorporating my feeding 50
apparatus is being installed, the belt I3 is car
ried around the pulley 22, and the belt 9 carried
through the passageway 23 and around the pulley
30, thence passing underneath the hopper and
back into/ engagement with the belt l3. The
belt l3 in Figure 1. With reference to Figure 4

it will be seen that the troughin the cover belt
between the pulleys 22 and 30, rests upon the

slides H. The slide supporting assembly, con

adjusted as to height until the belt 9 passes 60
nels 2|, so that there is no escape of material‘
into proper interlocking engagement with the belt
between the belts as they come together.
The carrier belt 9 travels towards the feeding |3 underneath the pulley 22.
The hopper 5 which carries the guide angle
apparatus in the direction indicated by the ar
irons 2| is then adjusted in height and position
65 row in Figure 1 and in contact with the belt l3.
Upon reaching the apparatus it passes from out by adjustment of the stud bolts ‘I until the bot
tom edges of the vertical ?anges of the angle
of contact with the belt l3 and through a pas
sageway 28 enclosed within the material feeding irons are in close proximity to‘ the upper faces of
chute or hopper 29 which feeds material into the the belt 9. The bolts 25 which secure the angle

from the end of the passageway 28 passes loosened and the angle members slid until their 70

l4 and underneath the hopper 5. The belt 9 in curved outer faces of the belt l3 passing around

tioning of the mechanism, the various nuts are
tightened up.

. As the semi-circular orifice 35 in the forward
end of the hopper is slightly larger than the up
per portions of the partitions 3| which pass
through such ori?ce, the metal belt cover 33 is
then adjusted in height with regard to the par
ticular type of material to be conveyed. In the
case of free-flowing granular material, the mem
