FLY-TRAP.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed September 12,1903. Serial No. 172,994.

T0 at whone it mmty concern:

Be it known that I, OLAUS B. J AooBs, a citizen of the United States, residing at Roland, in the county of Story and State of Iowa, have invented a new and useful Fly-Trap, of which the following is a specification.

The invention relates to improvements in screens for doors and windows.

The object of the present invention is to improve the constructionof screens for doors and windows, more especially the means for permitting the flies to escape from the interior or inner face of a screen and for enabling such flies to be captured and destroyed.

A further object of the invention is to provide a simple and comparatively inexpensive fly-screen of this character adapted to cause flies crawling upward to pass from the interior to the exterior and capable of trapping the same, so that they may be destroyed.

Another object of the invention is to provide a device of this character which will also be adapted to capture flies crawling upward on the exterior of a screen and to enable the trap or receptacle to be readily removed from.

the screen for baiting it or destroying captured flies.

The invention also has for its object to provide a screen having a fly trap or receptacle adapted to be readily collapsed and folded against the screen to enable the latter to be compactly arranged for shipping and storing.

lVith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is an elevation of a portion of a screen provided with a fly-trap constructed in accordance with this invention. Fig. 2 is an end elevation of the same. Fig. 3 is a vertical sectional view of the same. Fig. 4: is a' detaii perspective view of a portion of the screen, the trap or receptacle being removed. Fig. 5 is a detail perspective'view of a portion of the fly-trap. Fig. 6 is a similar view material which constitutes the body portion of the trap or receptacle. Fig. 7 is a detail view of a portion of the trap or receptacle, illustrating a slight modification of the invention. Fig. 8 is a vertical sectional view illustrating the modification of the trap. Fig. 9 is a detail view of a portion of the corrugated strip of the trap shown in Fig. 8. Fig.-10 is a sectional view illustrating the manner of mounting the pivoted end or door. Fig. 11 is a sectional view illustrating the preferred form of the invention.

.Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a screen-frame having a corrugated fly-escape strip 2 interposed between its top bar or piece 3 and the upper edge of the screen material 4. The screen may be either a door or window screen, and the screen material is wire-gauze of the ordinary con-- struction. The fly-escape strip 2 is con structed of sheet metal or other suitable ma terial, and it is provided at intervals with transversely-disposed corrugations 5, consisting of approximately semicylindrical bends, which extend outward from the intermediate straight or flat portions 6 and which are provided at intervals with perforations for the reception of fastening devices 7. The straight fiat intermediate portions are fitted against the with dow or door screen frame, as clearly shown in Figs. 2, 3, and 4 of the drawings, and every other one of the projecting portions or corrugations 5 is perforated, and the fastening devices 7 secure the upper edge of the screen material and the corrugated strip to the screenframe. The intermediate portion 6 may also be provided with perforations for additional fastening devices when desired, The pro-' jecting portions 5 of the fly-escape strip space the upper edge or portion of the screen material from the top of the screen-frame and form fly-escape openings or passages to permit flies crawling up the screen to pass from the interior or inner face of the same. The upper edge of the screen material 4 extends upward beyond the fly-escape strip to provide a projecting flange or portion 9, and the screen material is of suflicient length for this purpose.

A strip 11 of wire-gauze or other suitable material is interposed between the fly-escape strip and the top of the screen-frame and is extended above the former to provide a projecting flange, which is arranged parallel with the flange 9 to form a transverse passage the entire width of the screen. This strip 11 is secured to the screen-frame by the fastening devices for securing the fly-escape strip to the same. The fastening devices 7 also secure L-shaped plates or brackets 12 to the outer face of the screen material, and these L-shaped plates or brackets, which are rigid with the fly-escape strip, form outwardly-projecting supporting-flanges, which space a fly trap or receptacle 13 from the outer face of the screen material 4 to form an upwardly-extending passage for directing the flies that crawl upward on the exterior of the screen into the fly trap or receptacle. The plates or brackets are arranged at intervals.

The fly trap or receptacle is supported by inclined rods or pins 14, having pointed ends 15, which are embedded in the top of the screen, the outer portions of the rods or pins extending upward and outward at an angle to the screen to receive the trap or receptacle, which is adapted, owing to the inclination of the pins or rods, to wedge itself against the top of the screen,whereby it is firmly held in position on the same and is prevented from being accidentally loosened by the slamming of a screen-door. The body portion of the trap consists of a sheet of screen material, which is rolled into an approximately cylindrical body, the edgesof the material being overlapped and spaced apart to permit the flies to pass inward into the trap or receptacle. The rear edge of the body of the trap is provided at intervals with slots or openings 16 and is arranged against a strip 17, which is provided with eyes 18, preferably consisting of staples embedded in the strip and extending through the slots or openings to receive a locking-rod 19. The locking rod 19 is arranged on the exterior of the screen material of which the body of the trap or receptacle is constructed, and it securely holds the said material against the strip 17. The strip 17, which is preferably constructed of Wood, has a beveled lower edge,

' which fits against the top of the screen-frame to facilitate the wedging action of the trap or receptacle. The terminals of the locking Wire v or rod are bent at an angle, as shown, to retain the rod in the eyes of the strip; but any other suitable means may be employed for this purpose, as will be readily understood.

' The inner edge of the body of the trap or receptacle is spaced from the beveled or Wedgeshaped strip by a corrugated strip 20, and it is extended beyond the same to form a projecting flange 21.

The corrugated strip is perforated at intervals to receive fastening devices 23 for securing the parts together. The straight intermediate portions of the corrugated strip of the trap or receptacle are fitted against the beveled or wedge-shaped strip, and they may be perforated to receive additional fastening devices, if desired. Any number of fastening devices may be employed for securing the necessary strength of the parts, as will be readily understood. A strip 24: of wire-gauze or other suitable material is interposed between the corrugated strip and the beveled or wedge-shaped strip and is extended above the same to provide a projecting flange, and the latter is arranged approximately parallel with the flange 21 to form an intervening space or passage for directing the flies into the trap or receptacle. Instead of employing a strip of wire-gauze to form this flange for cooperating with the flange 21 a strip 25 of celluloid or other suitable transparent material may be employed for this purpose, as shown in Fig. 7 of the accompanying drawings. The corrugations or bends of the fiy-escape strip of the trap form sockets for the reception of the inclined rods or pins, which fit snugly in such sockets and which are arranged at intervals, a suflicient number being provided to aflord a firm support for the trap or receptacle. The trap or receptacle may be readily placed on and removed from the pins or supporting-rods, and when shipping or storing the screen the rear edge of the body portion of the trap or receptacle may be unfastened to permit the screen material thereof to be unfolded against the flyscreen. This will enable the parts to be compactly arranged, and the ends 26 and 27 of the fly trap or receptacle are secured to the body portion by suitable fastening devices, which are adapted to be readily Withdrawn in folding the fly trap or receptacle. When the overlapped ends of the receptacle are detached, the cylindrical body portion may be readily stripped from the end pieces to fold it against the screen. The end 27 is pivoted by fastening devices 28 to form a door, and it is adapted to be turned on the pivots to afford access to the interior of the trap or receptacle for baiting the same when desired and for destroying or removing the captured The ends 26 and 27 are provided with extensions 29, constructed of Wire-gauze and adapted to form end walls for the passages at the inner and outer faces of the screen material of the frame 1. The screen material 4:, which has its upper portion arranged at an angle, may be connected with the screen frame at its side edges in any desired manner, a block or piece of screen material being preferably employed for this purpose. The trap may be baited with suitable material for catching the flies, if desired, and when a sufficient number have been captured they can be destroyed in any desired manner and can be emptied from the trap or receptacle, which may be readily removed from and replaced on the inclined supports formed by the rods or pins 14.

In Figs. 8 and 9 is illustrated a slight modification of the invention, in which the supporting-strip 17 is omitted. The body portion 30 of the trap or receptacle is extended to the top of the screen-frame and is doubled or bent backward upon itself to form a flange 31, which cooperates with the flange 32, formed by the inner edge of the body portion of the trap or receptacle. The inner edge of the trap or receptacle is spaced from the outer edge by a corrugated strip 33, provided at intervals with bends forming projecting portions and adapted to receive the inclined supports of the screen-frame. These bends or projecting portions are provided with triangular tongues or spurs 34, which are passed through the inner edge of the body of the screen material of the trap or receptacle, whereby the same is secured to the corrugated strip. These tongues or spurs are formed integral with the strip and are struck up from the same, being formed by partially-severed portions of the strip, as shown. The strip 33 is also provided with a series of tongues or flanges 34, formed integral with the strip and consisting of partially-severed portions bent outward or rearward and provided with perforations or eyes to receive a locking wire or rod 35. By this construction the rear edge of the body portion of the trap or receptacle, which is provided with openings to receive the tongues or flanges of the strip 33, is detachably secured to the said strip and may be removed when it is desired to fold the receptacle. The doubled edge of the trap or receptacle tits against the top of the screen-frame and is firmly wedged against the same.

The trap or receptacle may also be applied to a wall or window where there is no screen, and flies crawling upward will pass into the said trap or receptacle. The trap is preferbly arranged on the exterior of a screen; but it may be arranged at either face of the same, as desired.

The object of the celluloid strip 25 is torender the obstructions for preventing the return of the flies less distinct or visible, so that the flies will not be deterred from passing upward into the trap. The celluloid may be made very thin and flexible, and the spring or resiliency of the same may be such as to permit flies to readily press the strip aside without difficulty in passing upward, and this arrangement will effectually prevent flies from returning through the narrow contracted space or passage, as a fly in returning would be unable to force the celluloid strip away from the adacent flange and reenter through such space or passage.
