FLY-TRAP.

Specication of Letters Patent.

Patented Apr. 23, i918..

Application filed .Tuly `31, 1916. Serial No. 112,&03.

Y Traps; and I do hereby declare the followlili ing to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the class of fly traps, and has particular reference to those traps which are adapted to be associated with a door or screen, so that those flies or other insects which fly around the door or window openings will be caught instead of entering ihe house. j

rI`he principal object of this invention is to provide a trap of the type above-mentioned, which may be readily attached to a screen door, or awindow screen, and which is so designed that the draft or stirring of the atmosphere caused by opening the door will aid in the entrapment of the flies.

A further object of the invention consists in the construction of the trap whereby the appearance of the door is not materially aidected as to outside aspect, and which does not take up a great amount of space inside of the door.

More particularly, the invention has for its object to mount upon the inside of a screen door a device which will gather toward a single point all of those iies which congregate upon the outside of a screen door and to entrap them in a removable receptacle, which may be removed and cleaned as often as is desired without defecting the serviceability of the door, the entrapping device consisting of a chute-like compartment which has a closed receptacle at its apex into which the flies are induced to pass in an endeavor to escape from the chute-like compartment.

With the above and other objects in view, as will hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings.

ln said drawings Figure l isa front elevation of a door having my invention applied thereto,

Fig. 2 is a section on line 2-2 of Fig. i,

8 ie a section online M of Fig. l,

F ig. 4 is a section on line 1F-Ll of Fig. l, and

' Fig. 5 is a detail view showing a shutter d evice used in connection with my invention. p

Referring more particularly to said drawings, l represents the frame of a screen door, whose lower section 2 is provided with the usual screening. The upper section is covered upon the outside with a wire fabric 3 whose mesh is just large enough for a fly to pass therethrough. Upon the rear face of the door, and covering theupper section which is also covered by the wire fabric 3, is secured a net or inclosure 5 which is formed of small mesh fabric and bows inwardly from one edge to the other of the door, and from its upper and lower edges inclining to Ward a point 6, at the approximate.location of the trap 7. Above the point 6, the inclined portion of the inclosure forms a substantial concaved arc, so that a pocket or seat is provided upon which the trap7 is supported. Centrally of said pocket or seat, the inclosure 5 is provided with an opening 8, which provides an exit opening from the inclosure to the trap 7 when the latter is mounted in position. When the trap 7 is re moved, the opening 8 is closed by the cover 9, which consists of semicircular Aplates which meet along their straight sides, and are hinged at l0 to the rear side of the opening 8.

Mounted to extend through the opening 8, and into the trap 7 when the latter is in position is a chute or spout 1l. The spout or chute ll is formed of sheet metal, or other suitable material, and is cross sectioned as indicated in Fig. 4E so as to provide a series of interior and exterior channels along which the flies may travel in entering the trap. The spout is flared at its lower end as at 12, and has a continuous contraction toward its upper end, so that flies which have passed therethrough will not be likely to attempt to return by the saine passageway.

ylhe trap 7 consists ofV a globular recep tacle whose lower end is shaped to ht within the seat or recess provided therefor, and is held in vertical position by means of a hook 14. The bottom of the receptacle is pro vided with an aperture corresponding to the opening 8, and secured within the aperture is a vertical passage l5 of wire fabric which Ill@ tapers toward its upper end, and practically telescopes the chute or spout 11. Thus, flies which enter the chute 11 from the receptacle 5 enter the passage 15, and flies which mount the channels upon the outside of the chute 11 also find their way into-the passage 15, and eventually into the trap 7. @Theooperation of my improved fly trap has been clearly brought out in the course of theV above description, but it should be particularly noted that the conformation of the receptacle 5 is such that when flies which may have lighted upon the coarse mesh screen 3 are disturbed by the opening of the door, they are practically blown intoV the receptacle v5 by the draft which is set up, and

are furthermore induced to drift toward the point or apex 6, from which place it is naturalfor them to seek an outlet through the spout 1l and passage 4, but are entrapped instead.

'What'l claim as my invention is l. A fly trap, comprising in combination.f a compartment determined by a frame and including a side formed of large mesh material to permit the passage of flies, and a section to prevent the passageof flies secured to the opposite side of the frame and at a central point, into an upwardly directed concave seat having a central opening, a trap 'removably mounted on said seat over said opening, and a chute providing acommnnicating passageway between said compartment and said trap.

2. A fly trap, comprising in combination, a compartment determined by a frame and including a side formed of large mesh material to permit the passage of flies, and a section to prevent the passage of flies secured to the opposite side of the frame and at a central point, into an upwardly directed concave seat having a central opening, and a spout positioned. within said opening to project within the trap, said spout consisting of a tapered tubular member having a. plurality of exterior and interior channels and its lower end flared within the compartment.

3. A fly trap, comprising in combination, a compartment determined by a frame and including a side formed of large mesh material to permit the passage of fiies, and a section to prevent the passage of iiies secured to the opposite side of the frame and at a central point, into an upwardly directed concave seat having a central opening, a trap removably mounted on said seat over said opening, a chute providing a communieating passageway between said compartment and said trap, and closure elements hinged adjacent said opening to close the latter when the trap is removed.

in testimony `whereof I aihx my signature in the presence of two witnesses.
