As clearly shown in Fig. 5, the upper portion of
the guide plate 04 is shaped in the form of a plu
rality of ?ngers I04 having slots. I06 formed
therein for the passage of the bent wire spring
members 60, the spaces I08 between the ?ngers
I04 providing clearance for the eccentric disks
12, 13. The plate supporting bracket 86 is also
provided with slots for passage of the eccentric
disks as are the front wall II4 of the hopper and
the bottom plate I4, as shown in Fig. 2.
The individual belts 82 upon which the bullets
are carried forwardly in single ?le and arranged
end to end, run over pulleys H6, H8 and across
a guide plate I20 supported upon brackets I22 at
tached to the platen 40. The idler pulley H6 is
carried on a shaft, I24 supported between arms
I26 of a bracket I28 depending from the under

through into the orienting device at the proper
time.
In order to hold back the remainder of each
line of bullets so that only the foremost thereof
passes into the orienting device, a second trans
verse bar I12 is provided which is also slidingly
mounted in the side brackets I46, I48. The
transverse bar I12 is provided with a plurality
of depending ?at springs I14 arranged to extend
into the guideways I44 and the bar I12 is ar
ranged to be moved to the left, viewing Fig. 9, by
a spring I16 to dispose the ?at springs in sock
ets I11 cut in the upstanding rails I36, as illus
trated, to permit the bullets to pass. A stop
15 screw I13 is provided to limit the movement of
the bar I12 to the left, and movement in the op- '

When starting the machine, in order to assure

charged from the orienting device, as will be
hereinafter described. The bullets are advanced
along their respective belts until the fore
most bullet in each line comes to rest against an
individual stop ?nger I40 carried by and depend
ing from a transverse bar I42 arranged to be
moved into and out of alignment with the bullets
in the guideways I44. As herein shown, the
transverse bar I 42 is slidingly mounted in side
brackets I46, I48 attached to the forward end of
‘the guide plate 34. A spring I50 is arranged to
move the transverse bar in one direction to align
the ?ngers I40 with their respective guideways
I44, the bar being adjustably limited in its move
ment in this direction by a stop screw I52.
The
bar I42 is arranged to be intermittently moved
in the opposite direction, to permit the bullets
to pass, by connections including a cam I54
mounted on a cam shaft I56 and which is ar
ranged to cooperate with a roller I58 carried by
one arm I60 of a bell crank, as best shown in Fig.
6. The bell crank is pivotally mounted on a cross
shaft I62 and the second arm I63 thereof is con
nected by a link I64 to a lever I66 carried at ~
the lower end of a vertically mounted shaft I68.
The upper end of the shaft I68 carries an arm
I10 arranged to engage one end of the trans
verse bar I 24 to effect movement of the bar to the
left, viewing Fig. 10, to permit thebullets to pass

with a su?icient number of bullets to begin oper
ation, provision is made for rendering the bar
I12 ineffective to release any bullets until all
the guideways have been provided with bullets
from the releasing device. As herein shown, a
manually operated latch I06, pivotally mounted
at I90 in the side bracket I 46, is arranged to be
manually rocked to the right, viewing Fig. 9 to
the position illustrated in dotted lines therein, in
which position the latch I96 will engage a stop
member 200 provided on the bar I12 in order to
hold the bar back against the tension of the
spring I16. Thus, the ?at springs I14 are held
in position to engage and hold the lines of bullets
as they are delivered from the releasing device,
and when a sumcient number of bullets have
been supplied to start operation, as may be ob
served through the transparent cover I38, the
latch I96 is rocked back out of the way to per
mit normal operation of the device, as above de
scribed.
From the description thus far it will be ob
served that a transverse row of bullets compris
ing the foremost bullets in each line thereof is
periodically released into the orienting device
I32 and that when the bullets arrive at the
orienting device they may be pointed head ?rst
or tail ?rst according to the position in which
they were released from the feeding device I8, as
