FLY-SCREEN.

SPECIFICATION forming part of Letters Patent N o, 563,314,`dated uly '7, 18,96.

Application filed April lo, 1896.

.To @ZZ whom it may concern.'

Bc it known that I, THOMAS H. ScHUErz, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Fly- Screens, of which the followin gis a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in ily-screens; and it consists in the novel arrangement andcombination of parts more fully set forth in thespecilication and pointed out in the claims.

In the drawings, Figure l is an elevation of a screen-door viewed from the inside'of the room to which it leads. Fig. 2 is a vertical section on .fr 0c of Fig. l. Fig. 3 is a similar section of a portion of the door with the screen removed. Fig. 4- is a detail showing the block which retains in place the deflected portion of the screen or wire-netting, and Fig. 5 is an inside elevation of the parts shown in Fig. 3.

The'object of my invention is to construct a ily-screen for doors, windows, and the like which, when the door or window screen is closed, permits any stray iiies in the room that might land or mount on the screen to find their Way along the screen or web out into the open without danger of thellies returning into the room through the opening from which the insects emerged or found their way out. In detail the device may be describedvas follows:

Referring to the drawings, l l represent the side members of the frame of a door-screen, ornamented with suitable scrollwork 2 2, the said side members being connected along the length thereof by a series of cross pieces or

members

3 and 3 flush with what corresponds to the outside surface of the door when hung.

4 represents the terminal bars or members of the frame. 5 represents a series of sheets of wire netting or webs extending across the width of the opening of the frame, and lapping a suitable distance beyond the line of the inner edges of the side members to which the sides of the screens are securely fastened and covered by suitable beading 6. In the present instance, the lower web 5 is secured serial Np. 587,801. (Np'mpiel.)

i able triangular cut-away portions or notches formed along the inner lateral faces of the side members l. The depth of each triangular-notch thus cut extends to the 'rear surface of thev cross pieces or members 3, to which rear surface the upper edge of the deflected portion 5' of the web is'secllred by beading 8.

To retain the deflected portion of the web firmly against t-he basal ledge 7 of the notch, suitable triangular blocks 9 are superposed over the edges of the web resting on the ledges 7 and nailed to the sides of the cut-away portions, the dimensions of each block being such that they accurately fit the cut-away portion, and come flush with the inner surface of the members '1.

In the present construction of the screendoor the straight edge of each block has cut therein a suitable notch or miter lO, in which rest the opposite ends of the inner cross-pieces ll, to which the basal or lower edge of each successive screen is secured and covered by suitable beading lo". The pieces ll break joint with the pieces 3, being relatively located below the latter when the door is hung. The upper edge of the uppermost web is of course secured directly to the upper transverse member 4. By the present construction, when the door is properly hung, a suitable space is left between the deiiected portion 5 and the lower end of each succeeding web, and when a fly alights on one of the webs 5 on the inside of the door, the insect (whose tendency is to always walk up) will pass into theV space formed between the overlapping ends of any two successive screens or webs and find its way to the outside of the frame, when the probabilities are that it will not return by the same route along which it emerged. The arrows indicate the direction the fly takes from the inside to the outside of the frame.

It is obvious that the frame as a whole IOO might be altered in mechanical details Without in any wise afecting the spirit of my invention.

16 represents beading disposed transversely and covering portions of the screens not otherwise previously referred to.

Having described my invention, what I claim is l. In a ily-screen, a suitable frame having side members, suitable cut away portions formed along the inner faces of the side members, cross-pieces disposed along the outside surface of the frame, the maximum depth of the cut-away portions being such as to lead or extend to the rear surface of the cross-pieces, a screen having a deflected portion and having its sides disposed along the basal ledges of the cut-away portions, means for retaining the deflected portions of the screen against the basal ledges, and means carried by or forming a part of the frame for retaining the base of the next succeeding screen, substantially as set forth.

2. In a fly-screen, a suitable frame having side members, suitable cutaway portions formed along the inner faces of' the side members, cross-pieces disposed along the outside surface of the frame, the maximum depth of the cut-away portions being such as to lead or extend to the rear surface of said cross-pieces, a screen having a deflected portion and having its sides disposed along Jthe basal ledges of the cut-away portions, suitable blocks inserted into said cut-away portions and adapted to retain the deflected portions of the.
