LOUIS L. NAIL, OF JOURDANTON, TEXAS.
MACHINE FOR DESTROYING INSECTS.Specification of Letters Patent. Patented Dec. 29, 1914.
Application filed August 4, 1914. Serial No. 855,057.To all whom it may concern:
Be it known that I, Lois L. NAIL, a citi-
zen of the United States, residing at Jour-
danton, in the county of Atascosa and State
5 of Texas, have invented new and useful Im-
provements in Machines for Destroying In-
sects, of which the following is a specifica-
tion.
My invention relates to new and useful
10 improvements in insect destroyers and more
particularly to that class especially adapted
to the extermination of boll-weevils, which
infest young cotton plants and cause serious
injury thereto.
15 While my invention possesses various ad-
vantages over machines heretofore adapted
to this line of work, namely; the extermina-
tion of insects, a few particular objects will
be noted which are: to provide a machine,
20 simple in construction and operation; to
provide a machine of such construction that
proper adjustments may be made in the
operating parts so that said machine may
be accommodated to plants of various
25 heights; to provide a machine in which the
insect removing parts are constructed of sub-
stantial, soft, pliable and adjustable brushes
which sever the said insects from a delicate
plant without injuring same; to provide in-
3o secticide carrying means associated with the
insect removing brushes for receiving the
insects and destroying the same. With these
and other objects in view which will be-
come apparent upon reference to the accom-
35 panying drawing and specification, I will
proceed to describe my invention in which-
Figure 1 is a top plan view of my ma-
chine; Fig. 2 is a side elevation thereof
with one of the wheels removed for. sake
40 of clearness of illustration; Fig. 3 is a front
elevation of the machine on line 3-3 of
Fig. 1; Fig. 4 is a transverse section on
the line 4-4 of Fig. 1, viewing the machine
from the rear, and, Fig. 5 is an end view
45 partly in elevation and partly in section of
one of the insect removing brushes, and illus-
trating in detail a preferred embodiment of
the brush adjustment.
Referring now more particularly to the
50 various figures in the drawings by numerals
of reference, 1 illustrates the main support-
ing frame preferably rectangular in form
and constituted by the longitudinal bars
2, 3 and 4 and the transverse bars 5 and 6,
55 this superstructure providing a supporting
means whereby suitable brush mechanismnow to be described is mounted for opera-
tion. These brushes more particularly dis-
closed in Fig. 5 consist of a plurality of
independent flat plates 8, constituting the 60
main brush supports and each having an
inner marginal flange 9, through the me-
dium of which the various brushes are
mounted upon the angular shaft 10 by de-
tachable fastening devices permitting the 65
brushes to be independently removed for
repair or replacement should any one or
more become worn out or damaged at any
time.
Associated with each of the plates 8 and 70
mounted thereon is another flat plate 12
somewhat similar to its associated plate 8,
said plates 12 each having at its extreme
outer longitudinal edge an enla tgement 15
in which is formed a substantially deep .75
longitudinal groove 13, said groove serving
as a seat for the brush 14 and in which
groove the said brush is securely fixed by
any suitable means. The fact that the plates
12 are provided with the longitudinal en- 80
largement 14, not only permits of a better
construction- in which to provide the brush
groove but also forms a reinforcement where
the strain on the brush supports is possibly
the greatest. To permit of the adjustment 85
of the brushes independent of each other I
provide the plate 8.with a plurality of trans-
verse slots 16 each of which coperates with
locking bolts 17, the shanks of which pass
through the plates 12 and lie within the 90
said slots 16, whereby the manipulation of
the locking bolts 17 allows the plates 12 to
slide on plate 8 and be locked in the end
adjusted position. This feature with its
detail of construction forms a material part 95
of my invention as will be appreciated by
cotton growers, the brush adjustment above
described permitting the brushes 14 to be
so adjusted in the desired elevated position
with relation to the cotton plants that the loo
machine can be accommodated to young and
short plants or to other sized plants in such
a manner that the latter may be engaged at
the desired point in its height.
The shafts 10 upon which the brushes are 105
mounted or journaled in bearing 18 on the
transverse bars 5 and 6 of the frame 1 and
are provided at their forward extremity
with beveled cog gears 19, said gears being
keyed or otherwise secured to their respec- 110
tive shaft for rotation therewith, meshing
with the respective cog gears 19 or beveled1,122,410.
