Improvements in Sticky Fly Paper.
I, WILLIAM WILSON HORN of the firm of Horn & Son, of 151 Strand, in the
County of Middlesex, Patent Agent, do hereby declare the nature of this invention
(a communication to me from Otto Thum and William Thum both of Grand Rapids
in the County of Kent and State of Michigan United States of America Manu-
facturers trading as the O. & W. Thum Company) and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
What is known as sticky fly paper, as heretofore put upon the market, has
consisted of sheets of paper coated upon one side with an adhesive material.
Although these sheets are put in the form of packages with a number of sheets
laid one upon the other, to form such packages, the sheets are independent of each
other, and of the package, and are designed to be used separately. The sheets are
all coated on one side only with the adhesive material, and in packing, either two
are laid with the coated faces in contact, or each sheet is folded and thus the
uncoated backs only are exposed. The pairs of sheets thus arranged, are laid
together with the uncoated backs in contact, and form in sufficient number, the
ordinary package. With this arrangement and construction of sheets and package,
only half the surface of the paper is utilized for the entrapping of the insects, and
the arrangement also requires that a good quality of paper shall be used, to prevent
the adhesive material from oozing through the paper. This, while it would not
pass through the paper in sufficient quantity to form a practically adhesive surface,
is sufficient to cause the sheets to adhere, and render them impracticable to handle.
Our present invention has for its object to secure double the catching surface
ordinarily provided by utilizing both sides of the paper whether used in independent
sheets, book form or made in a continuous sheet or roll.
In the accompanying drawings
Figure 1 is a sectional view of a series of single sheets coated in accordance with
our invention.
Figure 2 illustrates the use of these sheets.
Figure 3 is a like view as Figure 2 excepting that the sheets are shown with a
confining border around the sticky material.
Figure 4 shows the invention applied to the folded form of sheets.
Figure 5 shows the form of paper of Figure 4 in use.
Figure 6 shows the further use of this form.
Figure 7 represents another way of folding the sheets.
Figure 7 is a plan of the package Figure 8.
Figures 8, 9, 10 and 11 show sectional views of a continuous sheet folded and the
way
of using it.
Figures 12, 13, 14 and 15 are similar views of a continuous sheet rolled with flat
upper and lower portions.
Figures 16, 17, 18 and 19 show a continuous sheet in the form of a cylindrical
roll.
Figure 20 illustrates a holder applied to the form shown in Figure 12.
Figure 21 is a detailed view of the holder.
Figure 22 is a perspective view of a support or frame for the holder.
In Figure 1 we have shown independent sheets of fly paper arranged in series one
upon the other. The lower sheet indicated at f, and the upper sheet a, are preferably
composed of the paper ordinarily used for fly paper as it must be free from holes so
as to avoid sticky material passing through its thickness to the outer uncoated

page_text: surfaces. Sheet f, is coated on side; upon this is laid the sheet e, which is coated
upon both of its faces, and upon this is laid another and another coated in like
manner, upon both faces until a suitable number has been provided, the upper sheet
of the series being laid upon the sticky surface of the last sheet and having its
under surface coated, with its upper surface free from the catching material, and
preferably composed of a superior grade of paper as stated above. In the use of
paper thus prepared the upper sheet a, separated from the series and laid upon
another surface upon its uncoated face, and thus there is exposed the coated surface
of a, and the upper coated surface of the next sheet b. As soon as the exposed
surfaces have become covered with flies or the moisture of the sticky material has
evaporated to such an extent that the flies will not be caught thereby, the sheet a,
may be thrown away and the sheet b, separated and laid with its upper face upon a
supporting surface, as by this time the sticky material has hardened to such an
extent and is so covered by flies that there is no danger of the material adhering to
the underlying supporting surface, but in order to guard against this it may be laid
upon a sheet of paper as shown in dotted lines in Figure 2. After the sheet b, is
removed its under surface and the upper surface of c, are exposed, and this is
continued until the supply of sheets is exhausted.
Thus it will be seen that we secure double the catching surface and as the
intermediate sheets may be laid upon a sheet of paper or in succession upon the
surface of the sheet a, which had been used, the paper of which these interposed
sheets are composed may be of very inferior quality as the presence of small holes
throughout it will not in any way affect the utility of the sheet.
It will be understood that the sheets as thus coated may be used in very simple
form as in Figure 1, or each sheet may be provided with a confining border to
prevent the flow of the sticky material to the clean margins of the sheet either as
shown in Figure 3 or by the use of any well known or improved form of border,
and in transportation and storage any known or improved means may be provided
for preventing the material from passing to the clean margins.
In Figure 4 we have shown the invention as applied to folded sheets and in this
form the sheets are arranged as the leaves of a book, the outside covers being coated
only on their inner faces the interposed leaves being coated upon both faces and
adapted to be used as in Figures 5 and 6. But after the cover A, is turned back
each leaf comprising two sides may be removed as soon as both faces have been
utilized.

We have shown in Figure 7 a modified form of package each sheet being folded
and coated upon both faces except the top and bottom leaves, a suitable binding
being provided for the folded side, this binding being shown at and serving as a
seal in this form to prevent the escape of the catching material from between
adjacent leaves at the back of the package.
The general principle of construction which distinguishes the packs shown in the
illustrations, from Figures 8 to 20, is the formation by the folding or winding of a
continuous sheet or web of paper, with the catching or as it is commonly called, the
sticky" material properly placed upon the web as or before it is wound or folded
into the pack.

The web of paper is cut or formed preferably of the width of the ordinary
sticky fly paper, and as shown in Figure 8, it is folded back and forth, beginning
for example with the part, which is approximately the length required for the
pack, and for convenience in handling it may be as long as an ordinary package of
Hy paper. The lower or outer side of the part - is not coated with the sticky
material. The fold is at z, and that part of the web between z and e is folded
down upon the part f-2. It is folded again at and then turned back to Y where
another fold occurs and the web is reversed, and so on to the completion of the
pack, the web being laid back and forth with even lengths, and bends or folds at
the ends.
It is not necessary that the web be covered continuously, or on both sides, with
the sticky material. Regularly occurring spaces are left across the web, which

page_text: may be uncoated on one or both sides where the bends, as x, y and occur. The
rest of the web may have both sides covered with the sticky material, where the
over and underlying faces meet, or only one meeting face may be coated, receiving
enough to yield a part to the over or underlying face, when these are in contact.
For example, double the amount usually required of the sticky substance may
be placed upon the lower part between and, and the underside of the part
may be left uncoated as it will take up enough from the surface below, with which
it is in contact. Then the upper side of the part e- is likewise coated with a
double quantity and so on. But both sides may be coated with an equal amount.
The last sheet space, between and a is uncoated on the outside, so that the
package may be handled, and none of the coated surfaces are exposed.
Figure 9 shows how this pack is used. The upper folded part - is opened
and turned back to the position shown, in which the uncoated side is down, and a
double extent of coated surface exposed from a tor and to b.
When these exposed parts have been sufficiently used, the folded part a― is cut
off and removed, and the part - next below is opened and turned to the left as
shown in Figure 10, its under surface being usually so covered with flies as to
prevent smearing, but it may be allowed to rest on a piece of ordinary paper. The
second part may then be cut off and the third part unfolded from 6-y and turned
back as shown in Figure 11, and the use so continued through the whole series of
surfaces.
In Figure 12, the same general feature of folding is included, but instead of
being folded back and forth, the web is rolled. Beginning at d, the interior
termination of the web, it is folded around at 2, 3, 4 and 5. The outside end of
the web, to the point 6 is left uncoated and thus the whole exterior of the completed
roll is free from the sticky material.
Figure 13 shows how the parts are exposed in use, the roll or pack being turned
over to the left, leaving two exposed surfaces as before, one being the uncovered
upper surface of the pack, the upper surface of Figure 12 being underneath in
Figure 13. When this has been exhausted, the extended part of Figure 13 is cut
off, and the pack turned over again to the left, leaving it as shown in Figure 14,
and a third turn to the left, after cutting off the extended end, leaves the pack as
shown in Figure 15.
Paper may be placed under the sticky part in this case also, when the sticky
surfaces are turned down, but when the sticky surfaces are covered or partially
covered with flies, and partially dried by exposure they do not adhere unless
heavily pressed.
Figure 16 shows the pack in the form of a cylindrical roll, in this all the surfaces
are covered, excepting the outside of the end, enough to cover the cylinder. It is
unrolled in use as shown in Figures 17, 18, and 19, parts being cut off as used.
It will be understood that the margins of the web, alongside the coated surfaces,
or all around the surfaces may be supplied with a confining border or dam of any
suitable material to prevent outflow of the sticky substance.
In Figure 20 we have shown a support consisting of a plate p, or wood or
equivalent material, fitted to the pack and folded therein. It has pintles 7-9
which are fitted to bearings in any suitable support or frame and instead of the two
pintles four may be used, one at each corner or other means of support provided.
We find it convenient to utilize the box in which the paper is transported or stored
as a stand or frame and provide it as shown in Figure 22 with two uprights 10,
folded against the bottom when not in use, but adapted to receive the pintles
when raised to a vertical position. The box thus protects the underlying surface
also.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A pack of sticky fly paper composed of interior sheets coated on both sides

page_text: and having uncoated margins and having the outside sheets or covers uncoated,
substantially as described.
2. A pack of sticky fly paper formed of a web having coated interior surfaces,
and wound or folded upon itself with uncoated exterior surfaces, substantially as
described.
3. A pack of sticky fly paper formed of a web, having coated interior surfaces,
wound or folded upon itself, combined with a supporting plate, substantially as
described.
4. A. pack of sticky fly paper formed of a web, having coated interior surfaces
wound or folded upon itself, a supporting plate and a box or frame having folded
standards adapted to receive the supporting plate, substantially as described.
