Improvements in and connected with Fly-catchers.
I, CARL BENDER; I., of Dotzheim, near Wiesbaden, in the Province of Hesse-
Nassau, German Empire, Manufacturer, 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 present invention relates to fly-catchers of the kind in which strips of any
suitable material are covered with glue after being drawn through a receptacle
filled with glue and then stretched.
Hitherto in these fly-catchers very long strips of paper have been used and
subsequently. pieces of a certain length were detached when the surface of the
paper was covered with flies. Then a new piece of paper was drawn out of the
receptacle.
This process could be continued until the whole strip was consumed'; but many
resulting inconveniences have proved that this manner of catching flies is not
a very advantageous one. I only will mention one point which has proved to be
an important drawback.
In fly-catchers of the kind hitherto used the strip of paper once used must be
replaced by a new one (which is quite a dirty manipulation) and the glue stick-
ing on such a piece of paper cannot be used again, after it has served once, as
the strips together with the flies sticking thereon must be thrown away.
In order to obviate these drawbacks I have constructed the fly-catcher forming
the subject matter of my present invention.
The chief feature of my fly-catcher is that a short strip of paper is used which
need not be replaced by a new one, after it has served once to catch flies. The
glue or other sticky material used for catching the flies can always be employed
again owing to the particular construction of my fly catcher.
In order to make my invention more clear, I refer to the accompanying draw-
ing, in which:
Figure 1 shows a vertical section through a fly-catcher,
Figure 2 is an elevation of the same.
a is a receptacle filled with glue. In the interior of this receptacle a guide-
roll 6 is provided serving to guide the strip of paper or other material c for catch-
ing the flies, in such a manner, that both extremities project above the slots & d'
provided in the bulged parts h of the cover e. This strip is of such a length that
when the one extremity just projects above the cover e, the other extremity,
extends beyond the cover a long way. The two extremities of this strip of paper c
are connected by means of a string f and may conveniently be provided with
handles or loops e as shown. The string f passes laid over a roller g so that
when the one extremity of the strip c is drawn upwards, the other extremity
descends and enters the receptacle.
By this manipulation the strip c will be covered with glue. If for instance,
as shown in Fig. 1 of the drawing, the righthand side of the strip c is drawn
upwards, the same will be covered with glue. The superfluous glue will be

page_text: retained by the edges of the slot through which the strip has to pass. If
now a sufficient number of flies stick on the strip, the lefthand extremity of
the same, is drawn upwards and the righthand side is drawn through the recep-
tacle. The flies sticking on the strip are removed from the same when passing
through the slots d or d. They fall upon the cover e and can be easily removed.
The glue of the strip taken off by the slots d d flows again into the receptacle a
through openings i. By the alternate raising and lowering of one side of the
paper strip, the fly-catcher is always ready for use while the glue having served
once, always returns into the glue receptacle. Should after a longer use the glue get
too dry or too thick, it is necessary to add some diluting liquid, and the glue will
again be ready for use.
Having now particularly described the nature of my said invention, and in
what manner the same is to be performed, I declare that what I claim is:-
In a fly-catcher, the combination of a receptacle (a) filled with glue, with a
guide-roller (b) provided in the interior of said receptacle, a strip of paper or
other material (c) guided over said roller (b), a string (f) connecting the two
extremities of the strip c and conducted over a roller (9), a cover (e) having
slots (d), openings (i) provided in proximity to these slots, the whole sub-
stantially and for the purpose as described.
Dated this 3rd day of March 1899.
