arm 14 has pivoted to it by means of a bolt
16 an extension 17. The extension, where
it is pivoted to the arm 14, overlaps said
arm, the extremity of which has a lug 18,
5 against which the extension abuts, so as to
move with the arm 14 and rock the shaft 12,
when a member on one of the wheels 2 en-
gages said extension. A coil spring 19 is
carried by the bolt 16, and has one end por-
10 tion 20 engaging the arm 14 and the other
end portion 21 engaging the extension, to
hold the same in contact with the lug 18.
It is to be noted that when the wheel 2
(which carries the tripping member 22) ro-
15 tates backwardly, the tripping member 22
will idly trip the extension 17, while the
spring 19 will return it to its initial position
in contact with the lug 18. A coil spring 23
is mounted upon -one end of the sleeve 9,
20 and has one end 24 engaging through the
portion 8 of the bracket 3, while its other
end 25 engages the arm 15 of theshaft 12.
However, when the planter is moving for-
wardly and the tripping member engages
25 the extension 17 of the arm 14, the shaft or
element 12 will rock in its sleeve bearing
against the. action of the spring 23. A seed
receptacle 26 is secured on the lateral por-
tion 7 of the bracket 3, by means of the bolts
30 27 and the nuts 28, there being collars 29
on the said bolts, to hold the receptacle 26
spaced on and from the part 7 of said
bracket. Pivoted by means of a suitable
pin 30 on the portion 7 of said.bracket 3 is
s5 a triangular drop feed plate 31, which is
between the portion 7 and the bottom of
the receptacle 26. The free end portion of
this plate 31 has an aperture 32, which
loosely receives the end portion of the arm
40 15 of the rocking shaft or element 12. The
bottom of the seed receptacle toward one
side has an elongated slot '33, with one. end
of which an aperture 34 of the plate 31 nor-
mally registers. An arch casing 35 has its
45 lateral flanges secured by the bolts or rivets
or the like 36 to the bottom of the receptacle
26, so that said casing will arch the greater
portion of the slot 33. Pivoted in the cas-
ing 35 upon the pin 37 is a guard 38,.the
50 free end portion 39 of which isheld in en-
gagement with the plate 31 by means. of the
coil spring 40, so that said free end portion
39, will, prevent any peas or seed from enter-
ing the casing 35, between one end of the
55 casing and said plate 31, as shown at 41.
A seed chute 42 having a lateral flange .43
is provided, and it is to be noted that one
of the bolts 27 passes through the flange 43,
to hold tbe chute suspended from the under
60 portion of the part 7 of -said bracket .3.
This chute .42 extends downwardly and in-
wardly, and its upper end is in registration
with an opening or aperture .44 of the part
7 of said bracket 3. As the -wheels-of theplanter rotate, the tripping member 22 on 65
one of said wheels will intermittently en-
gage the extension 17 of the arm 14, and
rock the shaft or element 12 against the
action of its spring 23, so that the arm 15
will oscillate the plate 31, the aperture 34 70
of which having received a seed or pea,
and when the aperture 34 registers with the
aperture 44, the seed or pea will drop through
the chute to the ground, where it is covered
by the usual teeth of the planter. As -soon 75
as the tripping device 22 passes the exten-
sion 17, the plate.31 will return to its initial
position shown in Fig. 4, by the action of
the spring 23. The plate 31 in one edge has
a notch 45. Pivoted upon one of the bolts 80
27 is an angular:lever 46, one arm of which
constitutes a handle 47, while the other arm
48 has an upstanding lug 49. To throw the
plate 31 out of operation, the handle 47 of
said lever 46 is grasped manually, then op- 85
rated, so that the upstanding lug. 49 will
ride against one edge of the plate 31, mov-
ing the plate until the aperture.34 is under
the casing 35 and the lug 49 . engages the
notch .45. In this case the rock shaft or 90
element 12 will have been rocked sufficiently
against the action of its spring 23, as to
dispose the extension 17 of the arm 14 out
of. the path of the tripping member 22,
thereby preventing the drop feed mecha- 95
nism from operating. The trip member 22
consists of an arm 50 having its'hooked end
51 secured by a screw 52 on one of the spokes
of one of the wheels 2, and mounted upon
the arm 50 is a spool or roller 53, there be- 100
ing washers 54 and a nut 55 to prevent ex-
cessive axial movement of the spool:or roller.
This spool or roller has an interior bushing
56, to prevent wear on the roller.
The invention having been set forth, what 105
is claimed as new and useful is:-
In combination with a planter, a seed re-
ceptacle having its. bottom provided with a
slot, a supporting bracket upon the frame
of the planter for said receptacle, said 110
bracket having an aperture.registering with
one end of said slot, a plate pivoted :on the
bracket between the bracket and -the bottom
of the receptacle and provided with anaper-
ture to normally register with the other end 115
of said slot, and means actuated intermit-
tently by a member on one of the wheels of
the planter to actuate said plate intermit-
tently, whereby. its aperture will intermit-
tently register with the aperture of the 120
bracket, to feed seed one at a time from the
receptacle, and a casing arching the greater
portion of the slot, to prevent the seed from
entering the aperture of the bracket until
the aperture of the plate registers with the 125
aperture of the bracket, and a. guard .piv-
oted in said .casing .and provided with ,a
spring to hold .it.in engagement with said'2
