JOHN NORTHCUTT AND MINER CRAWFORD, OF SILVERTON, TEXAS.
AGRICULTURAL MACHINE.Specification of Letters Patent.
Patented Dec. 30, 1919.
Application filed January 12, 1917, Serial No. 142,025. Renewed October 3, 1919. Serial No. 328,327.
To all whom it may concern:
Be it known that we, JOHN NORTHOUTT
and MINER CRAwFORD, citizens of the United
States, residing at Silverton, in the county
5 of Briscoe and State of Texas, have invented
new and useful Improvements in Agricul-
tural Machines, of which.the following is a
specification.
This invention relates to agricultural ma-
10 chines for tilling the soil, for planting and
covering seed, cultivating crops and other
like purposes.
The prime object of the invention is to
produce a simple and improved wheeled
15 frame structure which may be utilized as a
basis to support machines or devices of va-
rious kinds, thereby enabling various de-
vices, such as plows, listers or cultivators
of various kinds to be utilized in connection
20 with a single carrying frame.
A further object of the invention is to so
construct the said carrying frame as to en-
able proper adjustment and manipulation
of the machines or devices used in connec-
25 tion therewith to be effected without chang-
ing the structure of the frame.
A further object of the invention is to
simplify and improve the detailed construc-
tion of the carrying frame and the parts
30 thereof.
A further object of the invention is to so
construct the various parts or attachments
intended to be used in connection with the
carrying frame to particularly adapt the
35 same for such use.
With these and other ends in view which
will readily appear as the nature of the in-
vention is better understood, the same con-
sists in the improved construction and novel
40 arrangement and combination of parts
which will be hereinafter fully described
and particularly pointed out in the claims.
In the accompanying drawings has been
illustrated a simple and preferred form of
45 the invention, it being, however, understood
that no limitation is necessarily made to the
precise structural details therein exhibited,
but that changes, alterations and modifica-
tions within the scope of the claims may be
50 resorted to when desired.
In the drawings
Figure 1 is a top plan view of the carry,ing frame including the sub-arch and the
implement beam.
Fig. 2 is a longitudinal vertical sectional 55
view of the same taken on the line 2-2 in
Fig. 1.
Fig. 3 is a side elevation including also
the plow, a planter, the cultivator beams and
the coverers. 60
Fig. 4 is a rear view of the frame as seen
in Figs. 1 and 2.
Fig. 5 is a sectional detail view taken
through the axle and the sub-arch on the
line 8-8 in Fig. 1. 65
Fig. 6 is a perspective detail view of the
sub-arch and related parts.
Corresponding parts in the several figures
are denoted by like characters of reference.
Referring to the drawings, 30 designates 70
the axle arch having spindles "31 on which
the wheels A are supported for rotation;
said spindles being of such length as to give
an ample range of adjustment of the wheels
longitudinally thereof to enable said wheels 75
to be spaced various distances apart. The
wheels include hubs 32 which are recessed
for the reception of the spokes 33, the latter
being made of flat iron or steel. For the
purpose of securing the wheels in adjusted so
position on the spindles sand bands 36 are
provided, said sand bands having collars 37
engagingthe ends of the hub, and said sand
bands being. split and provided with clamp
bolts 38 by the tightening of which the sand 85
bands will be clamped securely on the spin-
dles adjacent to the ends of the wheel hubs.
The top frame is composed of side bars 39,
said side bars being formed of angle bars by
properly bending the same to form for- 90
wardly projecting brackets 40 that serve to
support the tongue 41, said tongue being
supported between the vertical flanges of the
angle bars and resting upon the horizontal
flanges of the same, said horizontal flanges 95
being slightly spaced apart for the reception
of the bolts 42, 43 which serve for the at-
tachment of the doubletree strap 44, the
latter being downwardly offset at its front
end for the reception of a doubletree 45 100
which latter is pivotally secured by means
of a bolt 46. The rearward end of the
doubletree strap is split longitudinally for
a portion of its length, as seen at 47, and1,326,773.
