20 Claims.’
This invention relates to a dispensing device,
and has special reference to a dispensing device
for depositing measured quantities of granular or
powdered material, as desired.
‘
The object of the invention is to provide a
dispensing device which will accurately measure
and deposit granular or powdered material in
timed succession, as desired.

7 Figure 9 is an enlarged fragmentary sectional
View showing the manner in which the hopper is
connected with the base plate to permit rotation
of the measuring disk.
‘
As illustrated in the drawings, the hopper l l 5
has a corded section l2, and this hopper may
be formed from sheet metal, as shown in Figure
5. At the bottom of the hopper is a‘?ange cast
Another object of the invention is to provide
10* in a device of the above type means whereby the, ing l3 provided with ears I 4 for receiving bolts
delivery of the material may be suspended with
out disconnecting the device.
‘

A still further object of the invention is to,
provide a device of the above type with agitator
“5 which connect said hopper with the base
plate l1.‘ Between the ?ange casting l3 and 10
base plate I1 is a disk l8 which is provided with
measuring cups l9. This disk is secured to a hub
imeans to insure capacity measuring for each " 2! which is freely rotatable, on a’ central shaft
deposit.

According to the invention, the device com
prises a container or hopper for the material, a
‘ base plate beneath said hopper provided with a
it
discharge opening, a disk provided with cups for
measuring the material to be deposited, a main
shaft for connection with the source of power,
a, central shaft, drive means. between said shafts,
a bell crank pivoted on the central shaft, a crank
25 on the main shaft for rocking‘ the bell crank,
means on one end of the bell crank for inter
mittently bringing the measuring cups into regis
tration with the discharge opening, means on the
3011
other end of‘ said-bell crank for forcing the ma
terial from the cup through the discharge open
ing, and means on‘ the central shaft, and ‘within
22, and it is‘ provided at its center and about the 15
shaft 22 with a conical partition 23 which has
its greatest diameter adjacent said plate, and
its smallest diameter approximately the diam
eter of the shaft 22 and at a point near the
upper end of said shaft. The upper end‘of the
shaft 22 is provided with an agitator frame 24
which has extending arms 26, and at the inner
end of these arms, agitating ?ngers 21 are piv
otally‘mounted, while spiral springs 28 are posi
tioned at the outer endsof said arms and inter- I
mediate the ends of said ?ngers, so that the
lower end of said, ?ngers is yieldingly urged
outward.

tended to be driven from any suitable driving
means on the tomato ?lling machine.
The hopper II is provided with a cover 4!
which ?ts down over the beading on the same,
as shown in Figure 5. The base plate I‘! is pro- 45
vided with an arcuate slot 42 extending entirely
through the same, while the disk I 8 is provided
with a rack 43 having the same number of teeth
44 as'the number of measuring pockets I9.
>It'will be understood that the disk It may be
of any desired thickness, so that the capacity of
the measuring cups may be altered at will. This
is accomplished readily by removing the fasten

The connecting means between the ?ange cast
ing l3 and base plate I‘! is shown in detail in
Figure 9. The disk l8 must be free to rotate.
The connecting means consists of a screw 46
having a screw driver slot 41 in its lower end,
and provided intermediate its ends with a shoul
der 48.
Above the ear M, the screw is sur
rounded with a small spiral spring 49 while a
wing nut 5| is threaded onto the upper end of
said screw, so that any amount of pressure de
sired may be exerted thereon without changing
the relative distance between the flange casting
The collar 9'! may be adjusted, as desired, to
provide the proper amount of tension to force
the plunger completely through the cups in disks
of different thicknesses, and when adjusted it
may be held securely in place by means of the Ill
set screw lfil. With the springs arranged as
shown an equalizing tension is provided thereon
and the plunger, which is forced down against
the disk before the cup is aligned with the dis 10
charge opening will ride upon the upper surface
of the disk, and when the same registers with
I3 and base plate [1. By this arrangement, the
disk I8 is always free to rotate without permit

the same therethrough, thus forcing all the ma
terial from the cup.

22 (see Figure 5). These parts are connected by”
means of a set screw 63 extendingthrough a
slot 64 in said casting, while relative position
between said bell crank arm 59 and casting (ii is
obtained by means of the set screw 66 extending
30

The casting 6! is provided with a ‘pin 68 exv-r
tending through the same,rwhile a trigger 69 is
pivoted between the lugs ‘II, and has its forward
end 12 pressed upward ,againstsaid pin, by vir-r
tue of the spring ‘[3, so that said pin is forced
up into the tooth 44, as shown in Figure _6, when
said parts are in registry. The outer end of the,
spring ‘l3 may be retained‘at the upper end of
the ledge 14 on said trigger so ‘as _to force the
forward end ‘I2v thereof ?rmly against‘ said pin
68, as hereinbefore described, or it may be passed
down from said ledgeQas shown by dotted lines
in Figure 6, so as to permit the forward end of’
said trigger to drop, as shown at 16 in Figure 6_.
The pin 68 will, therefore, drop, so that its upper
end will be at the line 'l'l shown inFigure 6 and,
out of contact with the rack 43 on the bottom
of the disk [8. The other armfl8 of the‘bell
crank 52 is provided with, a cam race 19, This
cam, race engages a roller 8| mounted on the/bot-V
tom end of a shaft 82. This shaft is journaled
at 83 and >84, and its upper end is provided with?
a link 86 which extends to and connects’the
upper end of a plunger shaft 81. This plunger,

assume their full outward swing, thereby sub
stantially undermining the material in the hop

the measuring cups.
It will be noted that the agitating ?ngers ro 35
tate in the opposite direction to the measuring
disk which insures an even distribution of ma
terial into the cups and a complete discharge of
all material from the hopper.
The machine in its construction is full-?oating
so that the same may be taken apart for clean
ing or for the renewal of any worn or broken
parts, and this may be done quickly and con
veniently by unskilled workmen.
