CORNELUS VERDUIN, OF CBOOK-STON, NEBRASKA.

SCREEN-DOOR STRUCTURE.

Application filed April 25, 1923.

T 0 aZZ whom it may concern:

Be it known that CoRNnLUs VERDUIN, a citizen of the United States, residing at Croo-kston, in the county of Cherry and State of Nebraska, has invented certain new and useful Improvements in Screen-Door Structures, of which the following is a specification.

This invention has reference to screen door structure for preventing the entrance of flies or other insects into houses during the summer time and its object is to provide means whereby the screen is rendered more efficient for keeping the flies out than has heretofore been the case.

Since most of the flies, which in spite of a screen door, find their way into a house come in through the opening at the top of the door when the door is swung ajar, the purpose of the device is to close that opening.

Another advantage is that the screen door cannot blow open past the center as is so often the case with outside screen doors.

In order to render the structure more efiicient than heretofore the contrivance opens and folds much after the fashion of a fan.

There is provided a member or strip of wood which may be two feet, six inches long and one-half inch in thickness and in width may taper from one and one-fourth inches to one-half inch.

There is also provided certain rods which are stationary and fastened to wooden strips. Other r ds are also stationary and fastened to the screen door. To these rods there is fastened a web of light canvas in substantially the shape of a segment since the circle of which the screen door is a radius and a shape defined by other of the rods does not have the common center, it is necessary that the cloth be fastened correspondingly so that the cloth will not pull. Extending through the canvas parts there is provided alight chain and the arrangement is such that the device must be reversible so as to fit both'right and left doors.

Hanging down from the rods there are rectangular shaped pieces of cloth which in conjunction with the structure give added protection against flies trying to get under the canvas when the door is swung open.

The invention will be best understood from a consideration of the following de: tailed description taken in connection with e acco p nyi drawings pa Serial No. 634,454.

of this specification with the understanding, however, that the invention is not confined to any strict conformity with the showing in the drawings but may be changed and modified so long as such changes. and modifications mark no material departure from the salient features of theinvention as expressed inthe appended claim.

In the drawings:

Figure -1 is a plan view of the screen frame structure with the door frame in cross section and the parts extended;

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a perspective view of a slidable rod entering intothe structure;

Figure 4 is an enlarged detailed view of one end of one of the strips entering into the structure; and

Figure v5 is a view of a casing by means of which the structure is assembled.

Referring to the drawings, there is showna frame 1 composed of spaced door jambs with spacing members 2 made fast at the top of the door to the said frame, the full width of the door with the spacing members fastened to the top of the door frame by screws 3 or any other suitable manner and including a block 4 fastened to the top of the door jamb by screws 5 which also serve to hold a series of bars 6 hinged at one end to a block 7 made fast to the member 91 by means of pins'8 arranged in a line transverse to the bar 2 and spaced apart crosswise of the block 7.

The bars or strips 6 radiate from the pivots 8 toward the margins of a cloth member 9 to which the ends of the bars or rods 6 are. secured by fasteners 10 and these bars are joined at the ends remote from the pivots 8 by chains 11 each of a length corresponding to the length. of the chains 11, the terminal one of the chains being secured to a hook 12 at one endof the terminal bars or rods 6. The bars 6 are splayed with respect to the block 7 so that the bars 6 move about the pivot 8 in spaced relation to each other so that the several bars 6 move about individual pivots 8 in turn movable in spaced relation to each other.

The end frame 1 has connected thereto by means of a hinge 13 a door 14 which may be turned in parallel relation with the member 2 or at right angles thereto.

Since the cloth member 9 changes its relaties o the a s 6 Whe h r i i h ng ar my GA relation or parallel relation to each other the cloth iii-ember 9 folds uponitself in one position or the other of the bars 6 and in order to compensate for this changing relation the cloth member 9 adjacent to the bar 14 is provided with numerous parallel slits 15.

Each member 2 is provided Witha through slot 16 in Which is lodged a web 17 Which may be made offibrous material such as cardboard or the like and held to each member 2 by strands 18 allowing. the Web 1 7 to turn about fasteningdevices 19 so as to fold against the member 2 as needed so as to allow the Web 17 to fold against the member 2, permitting the fabric 9 to be folded in such manner as to contract into the space occupied by the member 9 and thebars 6 or to permit the fabric to be stretched.

I The purpose ofthe Webs 17 is to exclude flies or other insects from the spaces between the bars 6. The members 2 are secured to the block 4: by screw connections 20 to permit the bars 2 to be swung about the screwsor pivots 20 toward and from the end member 2 or toward and from the eorrespodingv end bar or end member 14: as

occasion demands, the fly shields 21; made fast to the members 2 by the fastening devices 19.

What is claimed is: p

A screen structure adapted to be used in conjunction with a door hingedly mounted in a frame comprising a block adapted to be applied to the inner surface of the frame at the corner thereof, and adjacent the hinged edge of the door, bars pivotally mounted at one end upon the block and disposed transversely of the door and the door frame, said bars being provided with longitudinally disposed herfs leading in from the outer free ends thereof, a bar adapted to be applied to the deer frame, a bar adapted to be applied to the door, a flexible f abric material secured at its edges t0 the bars which. are applied to the frame a "l door respectively, the int ri-n'edi ate port of the fabrie being trained threuglr th provided in the pivoted bars and a: fl binding element connected with the outer edge of the fabric and secured at intervals to the said bars.

in testimony whereof I afl'ix my signature.
