page_text: I ZACH FRED XEVERS of the City and County of San Francisco in the State of
California United States of America do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of my Invention is to provide a simple and efficient device for attach-
ment to windows, walls, and other places where flies are apt to congregate and
which will contain fly poison, coal oil, or some adhesive material for catching and
killing the flies.
The Invention consists in an elongated trough especially adapted for the easy
reception, retention, and discharge of the flies and poison, for effectually preventing
the escape of the flies when caught, and for the easy attachment to a window sash
adjoining the window-glass or to a wall, all as hereinafter clearly set forth and
they pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which figure 1 is a perspective view of one form of my improved
fly catcher, representing it as applied to a window sash. Figure 2 is a vertical
cross section on the line xx figure 1. Figure 3 is a front elevation shewing a
modified form of trough similarly applied, and figure 4 is a central vertical cross-
section of the same. Figure 5 is a front elevation of a further modification applied
and figure 6 is a vertical cross-section of the same Figure 7 is a front elevation of
another modified form, and figure 8 a vertical cross-section thereof. Figure 9 is
a perspective view of another form modified for application to a wall or similar
plane surface, and figure 10 is a cross section of the same as applied. Figure 11
is a front elevation of a modified form of the catcher, in which the ends are recessed
for receiving the holding clips. Figure 12 is a vertical transverse section of the
same, and figure 13 is a perspective view of a catcher having its ends grooved for
the reception of the holding clips. Similar letters of reference indicate corre-
sponding parts in all the figures.
The trough A is preferably made of sheet metal in approximately semi-cylindrical
form.
Referring to figures 1 and 2, the inner wall of the trough is lower than the outer
wall and is made flat so as to fit squarely against the window sash B at its
junction with the lower sash C, and the trough extending entirely across the
window frame is held in such position by screws or nails D inserted in the inner
sides of the rail receiving the vertical hook-shaped strips of metal E soldered or
otherwise secured to, or formed integrally with the ends of the trough A. From
[Price 6d1

page_text: the inner wall of the trough A projects outwardly and downwardly the narrow
strip or guard A' so that the fles being caught in the poisonous or adhesive
material contained in the trough, cannot escape by crawling up the window pane B.
A notch or opening A' is formed at one end of the trough, for the easy introduction
and discharge of the fluid or other material thereon.
This form is preferred, in that the outer wall of the trough being higher than
the inner wall, the flies cannot readily escape.
In figures 3 and 4 a similar construction of the trough and its means of attach-
ment is shewn except that the inner wall of the trough is higher than the outer.
In figures 5 and 6 the walls of the trough are substantially of the same height
and the trough is shewn provided with tongues F which may be soldered or other-
wise secured to the trough and which are received in metal slips G attached to
the sill C.
Figures 7 and 8 serve to illustrate a modification in which the inclined guard A¹
is omitted and the inner wall of the trough is made somewhat higher than the
outer wall in consequence thereof. The trough is attached to the window by
means of horizontal off-set tongues H attached to the ends of the trough and
received in correspondingly formed vertical tongues I so that the trough can be
easily removed and replaced.
In figures 9 and 10 the inner wall of the trough is shewn considerably extended
to form a plate which is applied against a wall or other plane surface and is
attached thereto by nails, screws, or other suitable means. The outer curved wall
is provided with a downwardly inclined guard J to aid in preventing the escape
of the flies.
Oil and water, coal-oil, or any suitable adhesive or poisonous substance may be
used in the trough. The top edge of the inner wall should, in all cases, be in close
contact with the pane of glass, wall, or other surface to which the device is applied,
so that the flies which frequent the window, etc, will readily gain access to the
trough.
The trough A¹, shewn in figures 11 to 13, is similar to those already described,
differing only in being recessed or grooved at the ends for receiving the fastening
clips 1. A simple device is thus produced, which is very effective, convenient to
handle and inexpensive.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A fly catcher formed of a trough and means for supporting the inner wall of
the trough in close contact with the window glass, substantially as specified.
2. A fly catcher formed of the trough A open at the top closed at the ends, and
provided with the notch A and means for attachment to a window pane, wall, or
other surface frequented by flies, substantially as specified.
3. A fly catcher formed of the trough A having a flat inner wall, so as to be
held closely in contact with the surface to which it is applied, and provided with
a downwardly inclined guard J substantially as specified.
