engage the teeth of said ratchet 36 which
moves said revoluble disk 34, and.a spring

pawl 41 .actsto maintan said paw 4 in'
normal engagement with oie of the.teeth
of said ratchet 36. Titus,' by reason of 'the
reciprocatory movement imparted to said

mlbiptud"t~o engage the teeth' of theratchet'
25 30 to stop the revoluble disk 34 with one of'
the. nut-shaped apertuires directly above the
opening. 35 in the hopper bottom. Said
pl)Jwl 46 is connected to the:operating mecha-
nisma by means of a rod Si1, Wayich is pivot-
30 ally connected at one end to a. boss 'formed
on the end of the rock 'lever 38, and is slid
ably extended through a block 52' on said
pawl 40. A spring 53 mounted upon the
extendl-d end of said rod 31 and bearing
35 between said block 52 and the jan nuts 54
carried by the end of said rod 51, on the
forward stroke, imparts the forward move-
muent of the can 38 t the pawl 46, bring-
ing it into the position which prevents the

and on the return movement of the cm '88
the spring A3 is freed of tension and: the
- (ollair 55 coming in emtact with said: block
52 pivoted in the pawl 46), returns the paw
45 46 to a position which permits of t1me next
forward movement of the ratchet 36. That
part of the pail. 40 which comes 'in contact
with the ratchet 36 travels faster aid. far-
ther than the pawl 41 by reason of the po-
50 sitiomi' of the pivotal block' 52,-thuis permit
ting of the initial movement of the ratchet
36. The pawl 41 reaches the end of its for-.
ward movement a little previous to the lock-
ing position of the puiwi 4U with the ratchet
56 30, the momnentumi. of the revoluble disk
bringing the ratchet 36 and pawl 46.to the
locked position.
Pivoted 'on the' hopper bottom at corre-
spondingly opposite points, by means of
60 studs 56 and 57 are the bell crank levers 58
and 59. Bell crank lever 58 has one of its
arms exteied substantially diauieti'ically
across the bottom of the hpper and has a
reduced >ort.ion provided with a stud 60,
65 said stud 00 engaging and being slidable-in a bifurcated slotted mneniber 61 formed
omi\ .the' oppositely, projecting airm of bell
crank lever' 59, whereby as the levers are
rocked, a.. moveienit. of one will impart a
correspgnding'and equal mnovemuent to the 70
other. Suitabhie 'ieans are provided, such
as eil r.in : r1iimiterpos'(l between the

The lever 59 is coinnected to guide mmenniler

which is 'slidable in a. traisverse groove (6
