OTTO RANNEFELD, OF SHERWOOD, TEXAS, ASSIGNOR OF ONE-FOURTH TO ROBERT F.
HALBERT, OF SAN ANGELO, TEXAS.
INSECT DESTROYER.1,402,960.
Specification of Letters Patent, Patented Jan. 10, 1922.
Application filed December 24, 1920. Serial No..432,992.To all whom it may concern:
Be it known that I, OTTo RANNEFELD, a
citizen of the United States, residing at
Sherwood, in the county of Irion and State
5 of Texas, have invented certain new and use-
ful Improvements in Insect :Destroyers, of
which the following is a specification, refer-
ence being had to the accompanying draw-
ings.
10 This invention relates to insect destroyers
and has relation more particularly to a de-
vice of this general character especially de-
signed and adapted for use in the extermi-
nation of boll weevils and kindred life, and
15 it is an object of the invention to provide a
novel and improved device of this general
character wherein heat is employed as the
life exterminating agency.
Another object of the invention is to pro-
20 vide a novel and improved device of this
general character comprising a portable
member adapted to travel along a row of
plants with a pan or hood positioned to one
side of said row, together with pneumatic
25 means for dislodging the boll weevils or the
like from the plants and directing the same
within the pan or hood, said pan or hood be-
ing provided with a discharging agency for
said insects.
30 The invention consists in the details of
construction and in the combination and ar-
rangement of the several parts of my im-
proved insect destroyer whereby certain im-
portant advantages are attained and the de-
35 vice rendered simpler, less expensive and
otherwise more. convenient and advanta-
geous for use, as will be hereinafter more
fully set forth.
The novel, features of my invention will
40 hereinafter be definitely claimed.
In order that my invention may be the bet-
ter understood, I will now proceed to de-
scribe the same with reference to the ac-
companying drawings, wherein:
45 Figure 1 is a side elevation of an insect
destroyer embodying my invention,
Fig. 2 is a front view thereof,
Fig. 3. is a detail sectional view on the
line 3-3 of Fig. 1, and
5o Fig. 4 is a. similar view on the line 4-4 of
Fig. 2.
As disclosed in the accompanying draw-
ings, F denotes a frame, of predetermined
dimensions and- configuration and which is
55 provided at its opposite sides adjacent itsrear portion with depending standards 1.
The lower portion of each of the standards 1
is provided with a spindle 2 on which is
mounted a supporting wheel W.
* Operatively engaged with the forward 60
portion of the frame F at substantially its
transverse center is a fifth .wheel 3 from
which depend the standards 4. 'The lower
end portion of each of the standards 4 is
provided with a spindle 5 on which is 65
mounted a supporting wheel W'. The wheels
AS' permit .the frame F to be readily and
conveniently steered in accordance with the
requirements of practice. It is to be under-
stoodlthat.the device is adapted to be drawn 70
in any suitable manner but preferably by a
double team of draft animals.
The wheels W' are arranged inwardly of
the rear wheels W and said rear wheels ,'
are spaced apart a distance whereby the 75
same, when the machine is in use, closely ap-
proach the rows of plants at opposite sides
of the row being treated. The device is
particularly adapted for use in connection
with cotton plants and in order that the s0
wheels 'V will not break the plants, the
outer end portion of each of the spindles
2 has secured thereto the upper end portion
of a rod 6, said rod being disposed for-
wardly on an angle of substantially forty- 85
ii ye degrees and having, its lower end closely
approaching the ground line. As'the device
or machine advances, the rod 6 will serve to
deflect the portions of the plants which may
be extending in the path of travel of the 90
adjacent wheel W.
Mounted upon the central portion of the
frame F and adjacent the opposite sides
thereof arethe fan. casings C each of which
has dlepending therefrom a, spout 7 of a 95
length to closely approach the .ground. sur-
face. The lower .end portion of the spout
T is continued by an inwardly directed
nozzle 8. The casings C and the spouts 7
are so arranged that the nozzles-8 are spaced 100
apart in a direction longitudinally of the
frame F or in the direction of travel of the
device or machine, 'so that the air blasts
or currents discharging from the nozzles 8
will not interfere one"with the other. 105
Arranged within each of the casings C
is' a fan 9 of a conventional type including
a shaft-10 extending exteriorly of the casing.
In advance of the casings C, the frame F
supports a transversely disposed counter- 110
