To all whom it may concern: Be it known that we, OTTO THUM and WIL- LIAMv THUM, of Grand Rapids, in the county of Kent and State of Michigan, have-in- Vented a new and useful Improvementin a Combined Sticky Fly-Paper Holder and Trap, 50f which the following is a full, clean-and exact description. 1 Y

, Heretofore in the use of fiy-paper, as it has ioheen made by coating one side of a flexible sheet of-paper witha sticky substance which attracts and catches the flies, a number of disadvantages have been .metwith, more or s objectionable; and it is the object of our i 5 present invention to remove these objections at the same time to increase theefficiency ofthe fly-paper asa trap to attract and catch the flies. As the fly-paper is composed of. thin sheets and flexible, they are liableto be blown about by the slightestd raft, and,gas--o rdiuariiy u'sed,-the 'sheetsf'are simply laid about onconvenient-surfacesand thus are susceptible to drafts of'air. As the stickyimaterial is very adhesive, it will thus smear and adhereto any surface or article of furniture upon which it may be blown by .the'wind. "I Am per are free from the material and the ecu-- tral' portion only covered the paper has a" 0 tendency to curl up at the edges, which thus:

lessens the exposed sticky surface. Further, 'it has disadvantages as a trap, for the reason that the flies in approaching'the sticky mate rial from the unsmeared margins of the sheets .35 enter into it cautiously, and can disentangle themselves if they only get into it a little way, and we have found by observation that'many flies approach the sticky surface from the margins. To overcome all these objections 40 and to' provide a more convenient way of placing the material of the fly-paper than by carrying it in the hand, which is liable to smear the fingers and get upon the person of the one who is carrying it, we have provided and trap'provided with asupport for the flybe'near it. It lessens to a great extent the unsightliness 'of the fly-paper'. It prevents the sticky material from flowingin hot' weather 5 5 onto the surface upon which the paper rests, as the holder will I receive any such flow, and when the fly-paper is not requiredfor use the holder may be placed away and the sticky material kept moist for a greater length of time than when the loosesheets areexp'o'sed to the air. Our holder also 'combinesthe advantages of a trap, as it hinders the flies from approaching from the margin, the constructionv rendering it necessary for them to fly div 'rectly upon. the surface in order to ascertain its nature, as none of the unsme'ared portion of the paper appears within sight; and again, when theflies have once been caught upon the surface, they will not turn toward 7o the clean berdento escapdby reason'of the fact that the vholder is provided with anoverpaper which repels instead of attracts the flies, and they will thus struggle toward thev center and thus get deeper into the sticky p material. other objection is-th'at asthe edges of the pa- E j Our invention therefore consists of a holder paper,- and a rim arranged to overhang the margin of the fly-paper when; it is in place; and it consists, further, in details of construction, all as hereinafter explained.-

I In the drawings, Figure 1 represents aper- "spetive view of our improved holder and trap with a sheet of paper in place. Fig. 2 shows it covered. Fig. 3 is a section showing the construction of the rim. I r

In the drawings, A'represents the support ing-plate upon which the sheet of paper containing the sticky material is placed,with the sticky or covered surface uppermost. Hinged to this supporting-plate is a rim, B, which has upon its under face a rectangular frame;a, of suitable width, which,when in place upon the sheet of fly-paper,.presses its edges against the bottom plate, A, and thus holds it securely in place. It will be understood that all the fly-paper is made witha margin, which is uncovered by the sticky material, and the frame a bears upon this margin, so that it'never becomes smeared with the material. The rim 1 B extends'upwardly and inwardly from the t 15 gether.

frame a, the sides of the rim being of width sufficient to entirely conceal from view the nnsmearcd edge of the paper, and by reason of its elevation it is above the surface of the paper tothe extentof about half an inch. We

have found aboutan inch and a half to be the proper width for the rim. This covers up the uncovered portions of the sheet and shows only the sticky surface. WVhenthe sticky paper is placed in position and the rim B placed upon it, the. rim maybe held in place,so asto pneventany displacement of the p'aper, by any suitable kind of clasp or fastening device fast suing the edges of the rim and base-plate to- We have simply shown perforations through the rim and base-plate, and they may bfizggcured together by means of a string or a n.

It will be seen by reason of its construction thatall the disadvantages enumerated of the simple sheet-s heretofore used are obviated, an,dthe sheet is heldsecurely within the holder, which gives it a neat appearanceand enables it to be used anywhere with perfect safet andwithout liability-of smearing, even 40 that the rim covering said portions makes it shou d it be turned over. It forms, also, as

we have before mentioned, a perfect trap, as

the flies cannot approach the sticky surface except by crawling up the inclined rim, and 30 we make this rim preferably of appro'xi mately the same color as the @icky surface and varnish with a hard drying and shining varnisEF, so that the dies are led to believe that the stiokysurfaee is only a continuation .of the 5 material ofthe rim. 'As the rim is about a 7 half-inchv above the surface, they cannot apto investigate, but must fly directly upon it. They will not drag themselves toward the unsmeared portions, for the reason dark along the edges, and the natural tendentry of the fly is to struggle out toward the center, and thus few escape. When the holder fith'the stickysheet is not in use, an ordinarytards thedrying action and keeps it moist for a great length of time. Vhenin use, the cover ,=may simply be removed from the top and serve as "a' shallow tray to receive the holder.
