JAMES CRAWFORD, OF EL PASO, TEXAS.
FLY-TRAP.Specification of Letters Patent.
Patented Mar. 9,1915.
Application filed January 17, 1914. Serial No. 812,688.
To all whom it may concern:
Be it known that I, JAMES CRAWFORD, a
citizen of the United States, and a resident
of El Paso, in the county of El Paso and
5 State of Texas, have invented a new and
Improved Fly-Trap, of which the following
is a full, clear, and exact description.
An object of my invention is to provide
an improved fly trap to which the flies will
10 be readily attracted, and to which they will
find free and ready entrance; and a further
object of the invention is to so form the
trap that the trapped flies may be conven-
iently and readily disposed of, and the trap
15 be adapted for thorough and convenient
cleaning in order to preserve its sanitary
condition.
The invention will be particularly ex-
plained in the specific description following.
20 Reference is to be had to the accompany-
ing drawings forming a part of this speci-
fication, in which similar characters of ref-
erence indicate corresponding parts in both
views.
25 Figure 1 is a transverse vertical section
of a fly trap constructed in accordance with
my invention; and Fig. 2 is a plan view with
parts in section, on the line 2-2 of Fig. 1.
In carrying out my invention, two trans-
30 parent containers are provided, which are
generally in the form of glass jars, the one,
10, constituting a lure and trap chamber,
and the other, 11, constituting a collecting
chamber. Each container separately rests
35 and is supported on its own bottom 12, 13,
and the containers are separate and distinct,
except that one has a laterally tapering neck
14 entering a lateral orifice 15 in the other
container to afford passage for the flies from
40 the trap chamber to the collecting chamber.
In the bottom of one container a suitable
liquid or other lure or bait 16 is placed, be-
low a false bottom 17 provided with per-
forations 17a which are not of a size to per-
45 mit the passage of flies therethrough.
To afford an ample and free inlet for the
flies to the container 10 having the bait 16, a.
tubular inlet 18 is provided, presenting pref-
erably a wide circular mouth 19 having a
50 flange'20 supported at its outer edge on an
interior flange 21 on the container 10. The
said tubular inlet 18 extends downwardly,
the bottom 18a being preferably disposed
above the false bottom 17. Lateral outlet
55 passages 22 lead from the inlet 18, adjacentto the bottom 18a to the annular chamber 23
formed between the said inlet and the inner
surface of the container 10. The said cham-
ber 23 constitutes a trap chamber and com-
municates with the lateral passage provided 60
by the neck 14. The container 11 forming
the collecting chamber is provided with a
removable cover 24, which may be formed
with orifices 25 sufficiently small to prevent
the escape of flies. 65
With the described construction, the trans-
parent character of all the parts permits of
the flies at the interior being readily seen by
the flies on the exterior, and with the at-
traction of the bait and the large inlet tube, 70
the flies are induced to enter the inlet and
will readily find entrance to the trap cham-
ber 23. As the said chamber extends on all
sides of the inlet, the flies eventually arrive
at the lateral outlet 14 and pass into the col- 75
lecting chamber.
By providing the containers in the form
of jars, each adapted to rest on its own
bottom, the two containers may be more con-
veniently manipulated in preparing and 80
cleaning the trap. The construction permits
of a thorough cleaning of the several parts,
and the trap is maintained in a sanitary
condition; also the collecting chamber is
substantially a plain jar, except for its lat- 85
eral inlet passage, and the flies may be read-
ily destroyed therein by submerging the jar,
water finding ready entrance through the
orifices 25 in the removable cover.
Having thus described my invention, I 90
claim as new, and desire to secure by Letters
Patent:
A trap of the character described, com-
prising two separable glass containers, each
resting on its own bottom independently of 95
the other, the one glass container consisting
of a jar-like body constituting a collecting
chamber and having a lateral inlet opening,
and the other container constituting a trap
and lure chamber and comprising a jar-like 100
glass body, a tapering lateral extension en-
tering the inlet opening of the collecting
chamber, a removable glass cover having a
depending cylindrical inlet tube of glass open
at its upper end and having a closed bottom 105
end above the bottom of the body, the said
inlet tube having lateral outlets in annular
series adjacent to the closed bottom of the
said inlet tube, the cylindrical wall of the
tubular inlet being free from lateral pro- 1101,131,120.
