20of sheaves 54, 54, there being one located at
each end of the equalizing bar and a pair
located at the center of said bar. Trained
throiigi said sheaves 54 is a draft chain or
cable, one end 36 of which is attached to a
draft bar 57 which is pivotally connected to
a draft plate 58 attached in any suitable
manner to the plow frame in rear of its
longitudinal center; and the other end 59
of said chain or cable is attached to a similar,
draft bar 60 which is pivoted to a like draft
plate 61 connected. to the frame near the
front end thereof. The ends 56, 59 of said
chain or 'cable are trained over the end
sheaves 54 of the equalizing bar 47, and the
central or looped portion 61 of said chain
or cable is trained about the central pair of
shear es 54 of the equalizing bar 47 with the
bight of said looped portion of the chain or
cable trained about sheave 63 which is
mounted or the forward end of a third draw
.bar 64 that is pivotally connected to a draft
plate 65 thatt is attached to the plow frame
between the draft plates 58 and 61.
The plow is drawn forwardly askew, or
with the lonitudinal axis of the frame dis-
posec obliqudel to the line of draft, so that
the succeeding rear plows or disks 20 will
follow each other parallel to the line of
draft, wxith each plow slightly at one side of
the plow in front thereof.
In case the engine A should turn slightly
from a direct line of travel, as indicated by
the dotted lines in Fig. 2, the equalizing bar
47 will be swung obliquely to the line of
draft, hut the draft chain or cable will shift
in fe guide sheaves, the longer end 56 pay-
ing epiI to increase its length and the shorter
end being taken up or shortened to decrease
its length, There is no tendency, therefore,
upon slight swerving of the pulling engine
or motor, for the rear end of the plow to bet
swung out of the line of draft in a manner
to increase the angle of the plow frame to
the normal line of draft and thereby imper-
fectly plow the ground, such as.would occur
if the draft connections were non-equaliz-
ing. This feature of the invention may be
applied to gang plows of different construc-
tion where other is a tendency upon slight
turning of the engine, to swing the plow out
of the tine of draft.
A telescopic, flexible actuating member 70
extends rearwardly from the engine to the
plow, the rar end thereof being' connected
to the plow lifting devices at the plow and
the front end bei connected at it-forward
end to the engine or motor. whereby the
plows m ay be lifted from the ground. as
-fully st forth in my aforesaid prior appli-
(ation.
ha'uien the plow is to be moved from place
to piece Ov('r a roadway the actuating mem-
1er 70 is d1sonected from the engine, an d
ti draft link 46 is disconnected from thedraw bar of the engine. The engine may
then be hitched directly to the front end of
the plow frame, as to the forwardmost draft
bar G0, so as to draw the frame forwardly in
the line of its longitudinal axis. In order
that the supporting wheels and rollers may
trail and be held in paths parallel to the
line of travel of the plow frame when on
the road, and may trail and'be held in paths
parallel to the line of draft of the plow
when the plow is in operation in the field, I
I may connect the several rolling supporting
elements in a manner which will now be de-
scribed.
The front furrow and land wheels 22 and
23, respectively, are connected, as before
stated, by the link 25, and the rear furrow
wheel 26 and rear supporting and ioldh fg
roller 28 are connected by the link 30 (Fig.
1). The swinging stub axles of the hind
wheels 37, 38 are connected by links 72, 73
with the draft bars 57 and 64, respectively,
and said dra ft bars are connected by the
Short links 75, -76, respectively, with arms
77, 78 connected to the pivots of the support-
ig and holding rollers 33, 34. The sup-
)porting and holding roller 3M is connected
by a link 80 to the rear land -holding 'nd
supporting roller 28 and the rear furrow
wheel 26. The forwardmost draft har 60 is
releasabhy connected to the link 25 which ex-
tends between and connects the swinging
axles of the front ground and land wheels
22, 23, respectively, by means of a pin 82
which may be dropped through an opening
in said draft bar and said link.
When the plow is to be adjusted for tav-
eling on the road, the pin 82 is remo ed
from the forward draft bar 60 and link 25
and the draft bar 0O is permitted to swing
freely. The other draft bamrs al ujnd h4 iay .
be stung over fixed brackets 85, 8', fixed to
the plow frame at the sides of said draft
bars, so as to be parail'el with the longit--
dinal axis of the frame, and said draft bars
and brackets are apertured, as shown in Fig.
1. to receive pi ns.by which the parts are
locked together. When the draft bars 57
and 64 are thus swung to the center of the
frame, all of the rollers 28, 33 and 34, and
the wheels 26, 37 and 38 are swung info po-
sitiorns parallel with the ally; o the i o O
'frame. When the e ngin I: hI-"'
