STICKY FLY-PAPER.

SPECIFICATION forming part of Letters Patent No. 469,021, dated February 16, 1892.

Application filed May 28, 1891. Serial No. 394,434. No specimens.)

To all whom it may concern.-

Be it known that I, JAY HUNGERFORD SMITH, of Rochester, in the countyof Monroe and State of New York, have invented a certain new and useful Improvement in Fly-Paper, of which the following is a specification.

My improvement relates to fly-paper made in double sheets, one side of which is provided with sticky material and the other forms a flap or cover which turns down over it.

The invention consists in the peculiar folding of the edge of the paper, forming a double V, the lower fold forming an inclosure which prevents the adhesive material from running 0E, and the upper fold forming a cushion or pad that prevents contact of the two sheets at the edges, and also a finger-hold by which the paper can be easily opened.

In the accompanying drawings, Figure 1 is a perspective viewof a sheet of fly-paperprovided with my improvement partially folded and with one corner torn away to show the folding of the edges. Fig. 2 is a plan view of the same laid open. Fig. 3 is a cross-section in the folded position.

A A indicate the two halves of the sheet, which is folded in the center one half over the other to inclose the sticky surface. The edge of one half of the sheet is folded, as shown at a a. The edge is first folded over inward of double width and then folded back on itself, the free margin standing outward. This makes a double-V fold inclosing angular spaces, the lower one standing inward and the upper one outward, as shown.

By the construction above described the device is all made from one sheet of paper, the lower groove of the edge folding serving to prevent the escape of the adhesive material, while the upper loose flap serves as a cushion or pad to receive the upper sheet and prevent it from coming in contact with the lower one. These double folds make such a thickness at the edge that even with the use of very thin paper the leaves are kept separated at the edges. The loose flap also serves as a convenient finger-hold in opening the sheets.

Having described my invention, I do not claim a single fold; nor do I claim strips placed between the sheets to separate the same.
