JAMES ARCHIE MILLER, OF BEEVILLE, TEXAS.
PLOW ATTACHMENT.Specification of Letters Patent.
Patented July 6, 1920.
Application filed March 6, 1920. Serial No. 363.637.
To all whom it may concern:
Be it known that I, JAMES A. MILLER, a
citizen of the United States, residing at Bee-
ville, in the county of Bee and State of
5 Texas, have invented certain new and use-
ful Improvements in Plow Attachments, of
which the following is a specification.
The present invention relates to agricul-
tural implements and more particularly to
10 an attachment for use in connection with a
turning plow whereby the soil may be pre-
pared simultaneously with the plowing
thereof for reception of the seed, thereby
reducing the labor to the smallest amount
15 possible and enabling the land to be pre-
pared in a relatively short time.
The invention consists of a harrow attach-
ment adapted to be attached to a turning
plow whereby the land is harrowed at the
20 same time the earth is turned during the
plowing operation.
The attachment is of a nature to be readily
applied to any turning plow and is so con-
nected as to admit of its being thrown up-
25 ward out of the way when not required for
immediate use so that the plow may be used
in its ordinary capacity for turning the soil.
The invention furthermore consists of an
attachment comprising toothed bars which
30 are mounted to admit of adjustment of the
teeth so as to occupy a perpendicular or a
forward of rearward inclination at any de-
sired angle, said bars being mounted to yield
and thereby prevent injury to. the teeth of
35 the attachment in the event of a root, boulder
or other obstacle being encountered.
The drawings illustrate a preferred em-
bodiment of the invention. However, it is
to be understood that in adapting the same
40 to meet different conditions, various changes
in the form, proportions and minor details
of construction may be resorted to without
departing from the nature of the invention
as claimed hereinafter.
45 Referring to the drawings hereto at-
tached
Figure 1 is a perspective view of a part
of an ordinary turning plow provided with
an attachment embodying the invention, the
50 same being in operative position.
Fig. 2 is a detail view of one of the toothed
bars and the mounting therefor,
Fig. 3 is a view similar to Fig. 2 showing
the relative position of the teeth,
55 Fig. 4 is a sectional detail through the
bearing of one of the toothed bars,Fig. 5 is a detail view of the inner end of
a toothed bar and the mounting therefor
showing the latter hingedly connected to a
supporting bar. 60
Fig. 6 is a detail perspective view of an
element of a toothed bar mounting,
Fig. 7 is a detail view of the operating le-
ver and parts associated therewith whereby
the toothed bars are held in an adjusted 6s
position.
Corresponding and like parts are referred
to in the following description and indicated
in the several views of the drawings by like
reference characters. 70
Inasmuch as the invention is adapted to
be applied to a turning plow the latter is
illustrated in Fig. 1 and is of ordinary con-
struction comprising the usual land side 1 in
addition to the plow shovel 2, beam 3 and 75
handle bars 4.
The attachment is connected to the plow in
a manner to admit of its being thrown into
upward position so as to be out of the way
thereby enabling the plow to be used in its so
ordinary capacity. The attachment compris-
ing a plurality of toothed bars 2 which are
disposed in parallel position and mounted
for partial rotation and adjustment to admit
of the teeth clearing clods, roots and other 85
objects which would tend to disable the at-
tachment. The teeth 3 may be secured to
the bars 2 in any manner and as indicated
most clearly in Fig. 3, the upper ends of the
teeth are reduced and pass through openings 90
in the bars 2 and receive nuts on their pro-
jecting ends. In this manner the teeth may
be replaced or relatively adjusted as re-
quired. Each toothed bar is provided at or
near each.inner end with a rounded portion 95
5 which constitutes a bearing. As shown
most clearly in Fig. 1 pairs of bars are pro-
vided for the inner and outer ends of the
toothed bars and these several bars are chan-
neled and the bars of each hair are arranged ioo
with the channels facing inward. This is
indicated most clearly in Figs. 1 and 5. The
channeled bars are designated by the nu-
meral 6 and are connected by bolts 7. Plates
or struts 8 are interposed between the chan- 105
nel bars of each pair and serve to space them
apart the required distance. The opposing
sides of the struts are recessed as indicated
at 9 so as to receive the bearing portions 5 of
the toothed bars. The upper and lower cor- 110
ners of the struts 8 are notched as indicated
most clearly in Fig. 6 to provide clearance1,345,869.
