for the flanges of the channel bars 6. -The
outer sides of the struts 8 are grooved as in-
dicated at 10 to receive the bolts or fasten-
ings 7. The struts 8 may be of any length so
5 as to make provision for vertical movement
of the toothed bars whereby the teeth thereof
are enabled to clear roots, boulders and like
obstacles. A pair of struts 8 is provided for
each bearing portion 5 of the toothed bars 2
10 as indicated most clearly in Fig. 1. When
the parts are assembled the bearing portions
.5 of the toothed bars 2 engage the recessed
or channeled sides 9 of the struts 8 and are
retained in position thereby. It will thus be
15 understood that the toothed bars may be
turned to adjust the inclination of the teeth
and in any adjusted position, the toothed
bars are adapted to move vertically to en-
able the teeth to clear obstacles.
20 When the attachment is in position it is
held extended by means of a suitable rod 11
which is interposed between one of the han-
dle bars 4 and the outer end of the attach-
ment as indicated in Fig. 1. The attachment
25 may be. turned so as to occupy a vertical po-
sition and thereby be out of the way when
the plow is used for turning the soil simply.
The inner pair of channel bars is secured to
short bars 12 and these short bars are
30 hiligedly connected to a longitudinal bar 13
which in turn is suitably connected to the
land side 1 of the plow in any manner. The
outer ends of the toothed bars project be-
yond the outer pair of channel bars. Posts
35 14 are secured to the projecting ends of the
toothed bars 2 and extend vertically and are
pivotally connected to parallel longitudi-
nally disposed bars 15 and 16.
An operating lever 17 is pivotally con-
40 nected to the bars 15 and 16 and is provided
with a hand latch 18 of suitable construction
and arrangement. A toothed bar 19 is con-
nected to one of the bars as 16 and its teeth
cooperate with the engaging portion of the
45 hand latch 18 to secure the operating lever
and thelongitudinal bars 15 and 16 in the re-
quired position thereby fixing the adjust-
ment of the toothed bars so as to hold the
teeth in the required position. By proper
50 manipulation of the operating lever 17 the
toothed bars 2 may be rocked and secured in
adjusted position thereby holding the teethin the required position whether vertical or
inclined forwardly or rearwardly.
Having thus fully described my invention 55
what I claim, as new and desire to secure by -
Letters Patent, is
1. An attachment of the character speci-
fled, comprising relatively inner and outer
longitudinally disposed supporting bars, and 60
a plurality of transversely arranged toothed
bars having their end portions mounted in
the supporting bars and adapted to have in-
dependent or concurrent vertical movement
at both ends. 65
2. An attachment of the character speci-
fied, comprising relatively inner and outer
longitudinally disposed supporting bars, and
a plurality of transversely arranged toothed
bars having their end portions loosely jour- 70
naled in the supporting bars to have inde-
pendent or. concurrent vertical movement
and to turn for adjusting the inclination of
the teeth at any vertical adjustment.
3. An attachment of the character speci- 75
fled comprising supporting bars, toothed
bars having circular bearing portions, and
struts receiving the bearing portions of the
toothed bars between them and having the
opposing sides recessed to receive the circu- 80
lar. bearing portions of the toothed bars to
hold them in given position and admit of
rotation being imparted thereto and inde-
pendent vertical movement.
4. In an attachment of the character speci- 85
fled, a plurality of toothed bars mounted to
have a rotary movement imparted thereto,
elements disposed perpendicularly to the
toothed bars, parallel bars having said ele-
ments pivotally connected thereto, an oper- 90
ating lever pivotally connected to each of
said parallel bars and provided with a hand
latch, and a toothed bar carried by one of
said parallel bars and adapted to be engaged
by said hand latch whereby to hold the op- 95
rating lever and toothed bars in the required
adjusted position.
In testimony whereof I affix my signature
in presence of two witnesses.
