00., OF NEWPORT, WASHINGTON, A

SCREEN-DOOR FLY-TRAP.

Application filed May 26, 1916.

To all whom it may concern.

Be it known that I, EDGAR A. WARREN, a citizen of the United States, residing at Kellogg, in the county of Shoshone and State of Idaho, have invented certain new and useful Improvements in Screen-Door Fly-Traps; and I do hereby declare the following 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 new and useful improvements in a screen door fly trap and one of its objects is the provision of a device of this character, which shall be simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost.

' Another object of this invention is to provide a trap mounted in the upper end of a screen door and so constructed that the flies crawling upwardly upon the door will enter the same and be retained therein.

A further object of this invention is to provide a wire screen upon each side of the door frame and so arranged that the flies crawling upwardly thereon will enter between the wire screen and be guided into the trap.

A still further object of this invention is to provide a trough slidably mounted within the lower end of the door frame for catching the flies which may die before reaching the trap, and whichmay be readily removed for emptying the same.

A still further object of this invention is to provide the trap with a slidable tray which has secured thereon a guard which will guide the flies into the trap from the door.

WVith these and other objects in view as will become more apparent as the descrip tion proceeds, the inventionconsists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my mvention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a front elevation of a screen door fly trap, constructed in accordance with my invention,

Specification of Letters Patent.

Patented Aug. 11, 1917. Serial No. 100,146.

Fig. 2 is an end view of the same,

Fig. 3 is a vertical sectional view, illustrating the arrangement of the wire screen upon the door frame,

Fig. 4: is a longitudinal sectional view of the trap removed from the door,

Fig. 5 is a fragmentary sectional view, illustrating the entrance from the door to the trap,

Fig. 6 is a fragmentary sectional view illustrating one of the entrances for the flies to pass into between the wire screen upon the door frame,

Fig. 7 is a fragmentary sectional View, illustrating a transverse bracing strip to the door frame,

Fig. 8 is a similar view, illustrating the trough in the lower end of the door, and

Fig. 9 is a vertical longitudinal sectional view of the trap.

Referring in detail to the drawings, the numeral 1 indicates as an entirety, a door, consisting of side members 2 and 3 having top and bottom members 4 and 5 secured thereto. A transversely extending bracing strip 6 is secured to the side members 2 and 3 intermediate their ends and is provided with an elongated slot 7. A vertical stri S'is secured to the upper face of the bottom member 5 and extends upwardly through the elongated slot 7 of the strip 6 and is provided with its upper end reduced as illustrated at 9, which extends upwardly within a vertical slot 10 formed in the lower side of the top member 4. The vertical slot 10 is in communication with a transversely extending opening 11 formed in the top member a which receives a trap 12, which will be hereinafter more fully described.

Lower attaching strips 13 and 14 are secured to the side members 2 and 3 and an intermediate attaching strip 15 is secured to the vertical strip 8 and the strips 13, 14 and 15 are provided with their upper ends beveled as illustrated at 16 upon the outer faces thereof. The attaching strips 13, 1 1 and 15 terminate at a point central of the transverse strip 6 as clearly illustrated in Fig. 3. A pair of upper side attaching strips 17 and 18 are secured to the side members 2 and 3 and an upper intermediate strip 19 is secured to the vertical strip 8 and each of the strips 17, 18 and 19 are provided with their lower ends beveled as illustrated at 20 of Fig. 3 and overlie the beveled ends 16 of the strips 13, 14 and 15.

A wire screen 21 is secured intermediate its ends to the upper side of the bottom member 5 as illustrated at 22 and is bent to form a pair of relatively spaced and substantially V-shaped entrances 23 which are provided with openings in the apex portions thereof. The wire screen 21 is then bent back upon the \/shaped entrances 23 and extends upwardly to the transverse strip 6. The wire screen is then bent downwardly and rea'rwardly upon itself to form a second pair of V-shaped entrances intermediate the ends of the door 1. The wire 21 extends upwardly from the second pair of V-shaped entrances into the vertical slot 10 of the top member 4 and is bent downwardly and in spaced relation to itself and is secured to metallic strips 24 which are secured upon each side of the top member 4 and which are inclined downwardly and outwardly therefrom as clearly illustrated in Fig. 3. The downwardly bent portion of the screen within the vertical slot 10 is provided with openings 25 to provide a third entrance. In applying the wire screen 21 to the door 1, the attaching strips are removed and the wire is then nailed or otherwise seemed as illustrated at 22 to the upper side of the bottom member 5 and is then bent in the manner heretofore described to form the entrances, which will allow flies upon the outside of the screen door to enter into the space occurring between the wire screen upon each side of the door. The attaching strips are then nailed or otherwise secured to theside members 2 and 3 upon the wire screen 21 to securely hold same upon the door 1. Suitable triangular-shaped blocks 26 are secured upon each side of the bottom member 5 at the upper edge thereof for supporting the screen wire as clearly illustrated in Fig. 3.

The trap 12 consists of a casing 27 having an elongated slot 28 in the bottom wall thereof which is in communication with the vertical slot 10 in the member 4-. One end of the casing 27 is closed by a wooden wall 29 and is provided with its opposite end open to receive a tray 30. The tray 30 consists of a rectangular plate 31 having an elongated slot 32 which is in registration with the elongated slot 28 of the casing 27. A vertically extending wooden block 33 is secured to one end of the rectangular plate 31 by bending said plate upwardly and into an engagement with the sides of the block for forming a closure to the casing 27-, when the rectangular plate 31 is slid therein. The edges of the plate 31 are bent rearwardly upon itself to secure a wire screen '34 upon the rectangular plate 31 and which is bent upwardly in a substantially V-shaped formation as clearly illustrated in Fig. 5 to provide an entrance 35 to the trap 12. The V-shaped portion is provided with openings 36 whereby flies passing upwardly between the wire screen 21 may enter the trap, and be prevented from returning between the wire screen 21 or the fly passage.

A substantially U-shaped trough 37 having one of its ends closed by a substantially U-shaped clip 38 is slipped through an opening in the side member 3 and through an opening in the vertical-strip 8 and into the side member 2. WVhe'n in this position, the substantially u s'hap'ed clip 38 will engage upon each side of the side member 3 and retain the trough within the wire screen 21, providing a device which may collect all flies which may die and fall downwardly between the wire screen 21 and whereby they may be readily removed by withdrawing the trough 37 from the door 1.

From the foregoing description taken in connection with the accompanying drawings, it will be noted that there are three entrances provided upon each side of the door 1 for the flies to enter between the wire screen 21 which will guide them upwardly into the trap 12 After a great number of flies have been caught within the trap 12, the trap may beremoved from the top member 4 and the tray withdrawn to empty the flies therefrom. Toattract the tiles upwardly within the trap 12, the top wall of the casing 27 is provided with an opening which is closed by a screen 39 for allowing light to enter within the trap, whereby the flies as they crawl upwardly upon either the outside or inside of the'wire screen 21 will be attracted within the trap 12.

VVh'ile I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.
