UNITED. STATES PATENT OFFICE.
FRANC M. WIESEN AND JAMES S. CRISP, OF CRYERCREEK, TEXAS.
INSEOT-DESTROYER.
SPECIFICATION forming part of Letters Patent No. 763,823, dated June 28, 1904.
Application filed April 22, 1903, Serial No. 153,831 .(No model)To all whom it may concerns:
Be it known that we, FRANC M. WIESEN and
JAMES S. CRISP, citizens of the United States,
residing at Cryercreek, in the county of Na-
5 varro and State of Texas, have invented new
and useful Improvements in Insect-Destroy-
ers, of which the following is a specification.
Our invention relates to new and useful
improvements in insect - destroyers, and is
ro more especially a device for collecting boll-
weevils and other similar insects.
The object of the invention is to provide a
machine which can be readily drawn over a
field and which is provided with mechanism
15 whereby objectionable insects may be removed
by suction from the plants over which the ma-
chine is drawn.
The invention consists in mounting a suc-
tion-fan upon an axle and extending a tube
20 from the fan-casing downward to a point ad-
jacent to the ground. A suitable receptacle
is arranged at the discharge end of the casing
for the reception of the insects after the same
have been drawn upward through the tube.
25 Mechanism is employed for transmitting ro-
tary motion from one of the traction-wheels
of the machine to the shaft of the fan.
The invention also consists in the novel con-
struction and combination of parts hereinaf-
30 ter more fully described and claimed, and illus-
trated in the accompanying drawings, in
which-
Figure 1 is a perspective view of the ma-
chine. Fig. 2 is a rear elevation thereof. Fig.
35 3 is an elevation of the outer side of the fan-
casing.
Referring to the figures by numerals of ref-
erence, 1 is an axle mounted upon suitable
traction-wheels 2, one of which has a concen-
40 tric flange 3 upon its outer face. A tongue
4 extends from the axle, and arranged there-
on upon suitable standards 5 is a fan-casing
6, having a suction-tube 7 secured to the in-
let thereof and extending downward to a point
45 adjacent to the ground. A receptacle 8, pref-
erably formed of wire fabric, is secured in any
suitable manner to the casing, at the oulet.
thereof. The shaft 9 of the fan 10 within cas-
ing 6 has a pulley 11 thereon, upon which is
50 mounted a belt 12, which is arranged on a pul-ley 13, secured at one end of the shaft 14. This
shaft is journaled in standards 15, extending
upward from axle 1, and one of these standards
also serves to support a preferably horizon-
tal frame 16, upon which is journaled a shaft 55
17. Pulleys 18 and 19 are secured to oppo-
site ends of this shaft, and a belt 20 is mount-
ed upon pulley 18 and a smaller pulley 21 on
shaft 14. Another belt 22 is arranged on the
pulley 19 and the concentric flange 3 on. the 6o
traction-wheel 2. Brace-beams 23 are pref-
erably secured to tongue 4 and frame 16, so
as to hold said frame rigidly in position above
axle 1. As an additional brace we preferably
employ a rearward ly-extending arm 24, hav- 65
ing a standard 25 at its rear end which pro-
jects upward and is secured to the rear end of
frame 16. It will be understood that when
this machine is drawn forward rotary motion
will be transmitted from the traction-wheels 70
to shaft 17 through belt 22. Belt 20 will trans-
mit this rotary motion from this shaft to the
shaft 14, and belt 12 will transmit the motion
from shaft 14 to the fan 10. It will be seen
that by arranging the pulleys and belts in the 75
manner described and shown fan 10 will be
rapidly rotated and will suck air upward
through the tube 7 and discharge it from the
outlet in the casing 6 and through the recep-
tacle 8. When the tube is brought over a 80
plant having insects thereon, the suction will
draw the insects upward into the tube, and
they will be thrown violently into the recep-
tacle 8. The mesh of the wire fabric of which
this receptacle is formed is such as to prevent 85
the insects from passing therethrough, al-
though the air will be free to escape through
the outlet. It will be seen that the device is
extremely simple in construction and will ef-
fectually remove the insects from all plants 90
arranged beneath the tube 7.
In the foregoing description we have shown
the preferred form of our invention; but we
do not desire to limit ourselves thereto, as we
are aware that modifications may be made 95
therein without departing from the spirit or
sacrificing any of the advantages thereof, and
we therefore reserve the right to make such
changes as fairly fall within the scope of our
invention. 100No. 763,823.
