ROTARY FLY-BR U'SHATTACHMENT FOR SCREEN-DOORS.

SPECIFICATION formingpart of Letters Patent No. 7 24,052, dated March 31, 1903.

Application filed August 15,1902. Serial Ila-119,821. (No model.)

' a device ofthis class of some durable and inexpensive construction, designed to be attached to the inner surface of the screen-door near its free edge and to be extended vertically, and so arranged that as the door is opened the brush will be rotated rapidly, so as to keep flies or other insects from entering through the door opened, and when the door is released the spring in the fly-brush roller will operate to close the door and hold it in its closed position. 1

A further object is to provide the yielding spring-brackets for supporting the roller, so arranged that as the dooris opened or closed the strain and shock of the fly-brush will be reduced to a minimum.

A further object is to provide a two-part roller of this class having the parts so arranged that a supporting-bracket may be introduced between the parts of the roller and to provide means for connecting the roller parts, which means may be adjusted so that the roller may be fitted to doors of any ordinary size.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are obtained and hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows in perspective my complete brush-roller applied to the screen-door as in practical use. Fig. 2 shows an enlarged detail view of the brush-roller parts, the central portions of the rollers being broken away and the end portions of the rollers being illustrated in vertical section to show the construction of these parts; and Fig. 3 shows a detail top or plan view of the'upper rollerbracket.

Referring to the accompanying drawings, I have used the reference-numeral 10 to in dioate a door-frame and 12 a screen-door of ordinary construction, hinged at one edge to the door-fr'ameand havingatransverse cross-piece 13 near its central portion. Attached to the top cross-piece of the door-frame is a bracket (clearly illustrated in Fig. 3) made complete from a single piece of spring metal, its one end 14 being attached to the cross-piece 12 by means of the screws 15, and its central portion 16 being inclined outwardly and toward the free end of the door, and the outer end of the bracket is shaped to form an oblong loop 17.

The reference numeral 18 indicates a bracket similar to the one just described, except thatthe loop 19 in its outer end is round. This bracket 18 is attached to the lower cross-piece of the door. 7

Reference-numeral 20 indicates a bracket similar to the bracket 18, attached to the door near the free edge of door and in line with the central cross-piece 13, and this bracket projects outwardly from the door and toward the hinged edge thereof, as clearly illustrated in Fig. 1.

The reference-numeral 21 indicates a hollow roller, having in one end a central rod 22, upon which the roller may turn. This rod is provided with a spring 23, one end of which is attached to the rod and the other to the roller 21. As this spring-actuated roller device is the same as is now in common use on window-curtain rollers, a further description and illustration is thought to be unnecessary. The upper end of the rod 22 projects through a cap 24, and its projecting end is flattened at 25. Fixed to the central portion of the roller 21 are the flexible wings 26, preferably made of stiffened fabric.

At the lower end of the roller 21 I have provided a device for the purpose of connecting the roller 21 with a second roller and also for forming a journal to enter the bracket 20. This device, as clearly illustrated in Fig. 2, comprises a straight round rod 27, having flattened portions 28 nearits ends and having these ends pointed at 29. One of these pointed ends is inserted in the end of the roller 21 until the flattened portion 28 enters the roller. Thus the rod 27 is prevented from rotating relative to the roller. v

The reference-numeral 30 indicates a solid IOC wooden roller in line with roller 21 and connected therewith by having the opposite end of rod 27 inserted in its upper end, and in the lower end of the roller 30 is a rod or journal 31, having the flattened portion 32 inserted therein, and the flexible wings 33, similar to the wings 26, are attached to the roller 30.

The parts are assembled, as shown in Fig. 1, with the fiat end of the rod 22 in the upper bracket and with the central portion of rod 27 in the central bracket and the journal 31 in the lower bracket, and when this is done I provide a cord 34, having one end attached to the doorframe and its other end portion wound upon and attached to the roller 21.

In practical use I first attach the three brackets to the door-frame in such a manner that the openings in the brackets are in line. I then provide a rod 27 of such length that the upper end of the roller 21 may be placed in the upper bracket and the lower end of the roller may be placed in the lower bracket, and the said rod will be of suflicient length to enter the meeting ends of the said rollers, so that my device may be attached to doors of any ordinary size, and the brackets may be placed on the cross-pieces of the doors. Obviously if only one roller were provided the roller could not be supported by a'central bracket nor could it be adjusted as to length without some complicated and expensive adjusting device.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. The combination with a door-frame and a screen-door hinged thereto, of a number of yielding brackets attached to the door, a spring-actuated roller mounted in said brackets, a fly-brush attached to the roller and a cord wound upon the roller and attached to the door-frame, substantially as and for the purposes stated.

2. The combination with a door-frame and p a screen-door hinged thereto, of a springbracket fixed to the top cross-piece of the door and having an oblong loop in its free end, a second spring-bracket fixed to the lower cross-piece of the door and having a round loop in its free end, a third spring-bracket fixed to the central portion of the screen-door passed through the central bracket, and said journal supported in the lower bracket, and a cord fixed to and wound upon the upper roller and attached to the door-frame, substantially as and for the purposes stated.
