Improvements relating to Sticky Fly-paper.
We, HUGO THUM and WILLIAM THUM, of the City of Grand Rapids, in the
County of Kent and State of Michigan, U.S.A., Manufacturers, 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:-
This invention relates to certain new and useful improvements in sticky fly
paper, and relates particularly to fly paper put up in rolls having the sticky
material applied to both sides of the strip of paper or web forming the roll;
and the objects of our invention are, first, to provide, in a suitable form
for hanging, a strip of paper or web, a suitable core upon which the
web is rolled and to which a drip receptacle may be readily attached; second,
to combine with the core a web rolled thereon, and a receptacle so attached as to
prevent the web from unwinding too freely from the core, thereby enabling the
user to unwind only such portions of the web as are used at any one time, such
device forming in effect a clamp.
These objects we accomplish by means of the mechanism illustrated in the
accompanying drawing, in which―
Figure 1 shows an elevation of the roll, partially unwound, with the drip re-
ceptacle detachably secured to the core.
Figure 2 shows an end view of the same.
Figure 3 shows a modified form of the core and the attachments of the drip
receptacle to the core.
Similar letters refer to similar parts throughout the several views.
A represents the web, which is supplied with the sticky material, and which
is adapted to be wound upon the core D. D represents the core, which in the
example of our invention shown in Figs. 1 and 2 has a conical or other projection
at either end adapted to engage with the ears of the drip receptacle. B represents
the drip receptacle, which may be constructed in any suitable form, and provided
with ears or projections CC which engage with the core. In the example of our
invention shown in Figs. 1 and 2 these ears CC are adapted to fit over the conical
projecting ends of the core, while in the example of our invention shown in
Fig. 3 the ears project inwardly into cavities in the ends of the core.
We prefer
to construct the receptacle of metal, or other material which will give a spring
pressure between the ears and the core for the purpose of increasing the friction
between the core and the receptacle. This friction between the core and the re-
ceptacle may be increased by any suitable means. The object of the friction is
to prevent the web from unrolling by the weight of the receptacle and core and
to retain the length of web unrolled, mechanically, at any required point. The
device thus constitutes in effect a clamp. By this construction also the roll may
be completed and the receptacle applied by merely crowding it over the core so
that the ears of the receptacle will engage with the projections or depressions in
the core, as the case may be. The free end of the web is preferably provided
with an opening or hole adapted for use in hanging the web and roll in suitable

may be applied to prevent the web
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
1. A strip of sticky fly paper forming a web, a core upon which said web is
wound, a drip receptacle adapted to engage with the ends of the said core and
detachably connected thereto, substantially as described.
2. A strip of sticky fly paper forming a web, a core upon which said web is
wound, a drip receptacle detachably connected to the said core, and adapted to
press thereon so as to produce sufficient friction to prevent said web from un-
winding by the weight of the core and receptacle, substantially as described.
3. A strip of sticky fly paper forming a web, a core upon which said web is
wound, a clamp adapted to press upon the core so as to produce sufficient friction
to prevent the said web from unwinding by the weight of the core and clamp.
