JOSEPH A. LA RUE, OF SALM1\ON, TEXAS.
Specification of Letters Patent.
Patented May 20,1913.
Application filed January 10, 1913. Serial No. 741,308.
To all whomit may concern:
Be it known that I, JOSEPH A. LA RUE, a
citizen of the United States, residing at
Salmon, in the county of Anderson and
5 State of Texas, have invented certain new
and useful Improvements in Subsoil-Irri-
gating Implements, of which the following
is a specification, reference being had to the
10 This invention relates to new and useful
improvements in sub-soil irrigators, and
more particularly to an implement of this
character, whereby the water is placed be-
neath the top of the soil, the object of the
15 invention being to provide a cart or other
vehicle having a plow point carried thereby
and arranged in front of the discharge hose
to open a furrow into which the water is
discharged and having two shovel points in
20 the rear of the discharge hose to cover the
furrow after the water has been discharged
Another object of the invention is to pro-
vide a cart of the above character which will
25 possess advantages in points of efficiency
and durability, is inexpensive to manufac
ture and at the same time is simple in con-
struction and operation.
With the above and other objects in view;
30 the invention consists in the novel features
of construction and the combination and ar
rangement of parts to be hereinafter more
fully described, pointed out in the claims
and shown in the accompanying drawings,
35 in which-
Figure 1 is a side elevation of an irrigat-
ing cart constructed in accordance with my
invention. Fig. 2 is a rear elevation. Fig.
3 is a longitudinal sectional view, and Fig.
40 4 is a front elevation.
Referring more particularly to the draw-
ings, 1 indicates the frame of the cart which
is suitably mounted upon a shaft or axle 2
having the wheels 3 mounted upon each end
45 thereof. Mounted upon the frame 1 are the
spaced parallel beams 4 which are provided
with an inwardly curved upper face upon
which is -mounted the tank 5. Secured to
the other sides of the beams 4 are the curved
50 brackets 5' which extend outwardly beneath
the tank to securely support the same upon
the beams. Arranged transversely across
the upper side of the tank in the front end
thereof is a beam 6 to which is secured the
55 ends of a rod 7, the intermediate portion of
said rod being disposed beneath the beams 4
and the ends thereof passing up on each
side of the tank to prevent any lateral move-
melAt of the tank when resting upon the
Pivotally secured between the forward
ends of the beams 4 is a tongue 8 which is
provided adjacent its pivot ends with a lon-
gitudinal slot 9 in which is slidably mounted
a standard 10 of the plow point 11, said 65
standard being provided with an opening 12
in which is arranged the lower end of a
pivoted rod 13, the intermediate portion of
which is pivotally mounted upon the point
14 secured to one side of the tongue 8. The70
other end of said rod is pivotally secured to
the outer end of a lever 15 which is adjust-
ably mounted upon the standard 16 secured
to the front side of the beam 6 at one end
thereof. Thus it will be seen that by the 75
manipulation of the lever 15, the plow point
11 may be vertically adjusted so as to open
the shallow or deep furrow.
Secured to the rear of the shaft or axle 2
at the intermediate portion thereof, is a U- 80
shaped bracket 17, upon the intermediate
portion of which is pivotally mounted the
inner ends of the supporting bars 18, and
secured to the outer ends of the bars 18 are
the shovel points 19 which are adapted to be 85
disposed on opposite sides of the furrow to
close the same after the water has been dis-
charged from the tank, through the pipe 20,
into the furrow. Arranged between the
supporting bars 18 is i V-shaped member 9o
20', the ends of which are bent at substan-
tially right angles and pivotally mounted
within the openings 21 formed in said bars.
Pivotally mounted upon the tank, as
shown at 22, is an operating rod 23, one 95
end of which extends rearwardly and is bent
at right angles, the lower end thereof being
loosely connected to the V-shaped member
20' by means of the link 24 and the other
end of said rod is pivotally connected to one 100
end of the adjustable lever 25. The lever 25
is adjustably mounted upon the upper end
of the bracket 26 which is secured to the
rear side of the transverse beam 6 adjacent
the end opposite the bracket 16. Thus it 105
will be seen that the shovel points 19 may
be quickly and easily adjusted or raised
from the ground to permit of transporta-
tion of the cart from place to place.
The discharge of water from the tank 5, 110
through the pipe 20, into the furrow is con-
trolled by means of a pivoted valve member
