INSECT EXCLUDER;

. To all whom it may conce m:

I Be it known that I, DARsIn E. Enwnuns, a citizen of the United States, residing at Clinton, in the county of Henry and State of Missouri, have invented certain new and useful Improvements in Insect Excluders; and Ido declare the following tobc a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and-use the'same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to an improved device for excluding insects, from habitations and particularly to a novel device for preventing the passage of flies through the doorway of houses, equipped with the in vention. Experience has taught that flies congregate or swarm about the upper part of the doorway and they are usually found at the upper edge of the door and along the upper portion of the vertical edge of the door, usually above the height of a normal person. When the door is opened, the flies are disturbed and enter the doorway over the top of the door and pass the upper portion of the vertical edge of the door, then when the door is closed they are trapped within the room. They seldom enter from the bottom portion of the doorway because their passage would naturally be obstructed by the person entering or leaving the building through the doorway opening.

I have provided a novel means for preventing the liability of the flies finding access to the building through the space between the upper end of the door and the door frame or along the upper vertical'edge of the door.

The invention contemplates the provision of a horizontal wall or canopy in close proximity to, but slightly above the upper edge of the door. The top of the canopy or wall is in a plane parallel to that described by the upper end of the door when it is swung to and fro and I prefer to attach to the upper end of the door a flexible wiper or strip which will maintain a close relation between the canopy and the door during the swinging movement of the door.

My invention further contemplates a. canopy which is interchangeable for doors having right hand hinges or left hand hinges and the invention consists in certain novel Application filed September 24, 1924. Serial No. 739,596.

parts and combinations of parts, all of which will be specifically described hereinafter, reference being had to the accompanying drawings in which- Fig. 1 is a perspective view of a canopy constructed in accordance with my invention.

Fig; 2 is a fragmentary perspective View of one corner of a door with the wiper attached.

Fig. 3 is a perspective view of the canopy viewed from the top, parts being broken away.

F ig. 4- is a perspective View of part of the canopy frame, and

Fig. 5 is a similar view of another part of the canopy frame. I i

The door frame 1 is ofusual construction and its opening may be closed by a door 2 hinged in the usual way as by hinges, like the one indicated at 3 in Fig. 1. The door 2 is illustrated as a screen door. Along the upper edge is a fiexible'strip or wiper 4: and extending from the upper edge a suitable distance downwardly is a wiper 5 located along the free longitudinal edge 6 of the door.

Fastened to the door frame above the door is a canopy. The canopy is of novel construction. It is illustrated as consisting of straight bars 7 and 8 arranged at angles of about 90 and connected by, a bolt 9 which extends through an angular bracket 10 fastened to the door frame by a screw 11 or other suitable device. The bar 8 is offset as at 12 to provide a seat for the bar 7, see Fig. 1. The bars 7 and 8 are connected at their outer ends by an arcuate bar 13 which is shown as a quadrant, that is the bar is equivalent to one-fourth of a circle and it is received in offset portions or seats 14 and 15 on the bars 7 and 8.

The ends of the bars extend downwardly to provide stiffening fingers 16 and 17 to maintain the canopy fabric or cloth 1n proper position. The arcuate bar 13 is fastened to the arms 7 and 8 by bolts 18 and 18. The bolt 18 is illustrated as passing through the members 13 and 7 and through a bracket 19 which is fastened to the door frame by a screw or other suitable device 20. The bar 7 rests against the door frame. The bar 8 extends outwardly from the door frame but it is braced by a brace rod 21, one end of which may be fastened to the door frame 1, the other end being threaded and extending through a bracket 22 on the bar 8.

The t-hreadedend 23 of the brace rod 21 receires'a nut 24: by means of which'an adjustment may be made for taking up slack in the canopy frame. The bar'T is provided with an opening 25 through which the bolt 26'for the bracket 22 may be inserted when it is desired to use the canopy' for a door swinging in the direction opposite to the one illustrated in'Fig. 1. in that event the bracket 19' will be removed from the bolt 18 and located on the bolt 18. he bracket 22 will be swung over to the bar 7 and fastened in the opening 25. The bracketllll may then be swung" around at an angle of 90 to its present position whereupon the canopy frame can be erected on adoor swung in a direction opposite to that shown in Fig. 1. j

The canopy fabric 27 has a skirt 28 which extends along the arcuate edge 29 of the fabric portion 27. The bars 7 and 8 are inserted in hems 30 and 31 and the arcuate bar 13 is inserted in the he1n'32. is stiffened by'an arcuate stiffening bar 33.

The top of the canopy fabric is'positioned iir' substantially the location shown in Fig. 1 so The skirt that when the door is opened, the Wipers i. and 5 will remove the files from the under side of the top of the canopy and from the flies entering the room from the upper part of the door opening will be entirely eliminated. n

lVhatI claim and desire to secure by Letters-Patent is:;

1. An insect excluder for ('loorways comprising a fabric supporting frame, a bracket adjustabiy engaging the frame. and means on the bracket for attaclnueut to the door frame.

2. An insect excluder for doorways comprising a horizontally disposed bracket arm, means for securing the brachet arm to the door frame, an arcuate arm adjustably carried by the free end o l the first named arm, a fabric having; one edge supported by the arcuate arm. and means for securing the opposite edge of the fabric to the doorway frame. 7

In testimony whereof I aliix my signature.
