WINDOW-SCREEN.

Specification of Letters Patent.

Patented J une 25, 1918.

Application filed May 31, 1917. Serial No. 172,017.

To all whom it may concern:

Be it known that I, EMIL E. PEDo, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain useful Im provements in Window-Screens, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention has reference generally to improvements in that class of inventions known as rolling window screens and more particularly relates to a window screen.

As the primary aim and object this invention contemplates the provision of a window screen which will adequately prevent the passage of insects an'd the like into a room or other inclosure when arranged in a closed position and which may be rolled up out of the way in the manner of window shades when not in actual use.

It is an additional object of this invention to provide a device of the character mentioned wherein the window screen can be readily rolled up and will be prevented from spreading or becoming distorted.

The invention as a further improvement consists in the provision of a' window screen wherein a tight closure will be ei'ectedbetween the window frame a'nd the ends and sides of the window screen.

Among the other aims and objects of this invention may be recited the provision of a device of the character described with a view to compactness, and in which the number of parts are few, the construction simple, the cost of production low and the efficiency high.

Other'improvements and novel details of the construction and arrangement of parts of the apparatus will be brought out more in detail in the description to' follow, which for a clear understanding of the invention should b e considered in connection with the accompanying drawings forming a part hereof, and wherein is disclosed for the purpose of illustration a convenient and satis factory embodiment of the invention. It is to be noted in this connection that minor changes in the construction and arrangement of parts may be made without departing from the principle of operation of the various parts.

The preferred embodiment of the present invention is clearly illustrated in the accompanying drawings, in which- Figure 1 is a perspective view showing the device applied to a window frame;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fig. 3 is a detail of one of the roller brackets;

Fig. 4 is a transverse cross section of the window screen guide.

Similar characters of reference are employed in all the above described views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings, there is provided for the purpose of enabling a clear understanding of the present invention a window frame including sides l and a head 2 of any conventional form, and it is to be under stood that the construction of the frame forms no part of this invention.

- With a view toward providing improved supporting means a pair of substantially rectangular plates 3 are employed and are attached to the inner surfaces of the sides 1 adjacent the head 2 being arranged in opposed relation with respect to each other. Each plate is provided with openings 4 ad jacent the respective ends for accommodating securing devices 5 which are anchored in the sides and one plate is also provided with a slot 6 while the other plate is formed with an opening 7 positioned opposite to the slot 6for a purpose that will become apparent. The screening means in the present instance consists of a spring roller 8 similar in construction to the conventional window shade roller but possessing a stronger spring action. One of the trunnions 9 projecting from one end of the roller is journaled in one of the openings 7 while the other trunnion 10 on the opposite end of the roller is rectangular in cross section as is common in spring rollers and is mounted in the opposite slot 6 in a substantially stationary position as will be apparent. A piece of screening 11 formed of suitable mesh fabric has one end rigidly secured to the spring roller 8 and is windable thereabout while an elongated bar 12 is mounted transversely of the outer end of the screen 11 and serves in ei'ect as a weight to hold the screen taut when in an extended position Vso as to close the window frame.

Cooperating with the screening when it is a en it is not desired to use the screenin in an extended posltion are the guides 13 in the present instance formed of stri s of metal channel shaped in cross section. hese guides are secured in opposed relation on the inner surfaces yof the sides of the frame and vertically thereof terminating at the lower edge of the plates and at the sill of the window frame. The side edges of the screen when in an extended position are arranged in close relation with the guides so as to pre,- vent the passage of insects into the room or other inclosure. t

As .intimated means haye been provided for preventing the screening from spreading out when it is being rolled up into a closed position and in the present instance' consists of a guide roller 14 the trunnions 15 on the respective ends of which are journaled in the openings 7 on the plates and when this roller is in the position described it is arranged in close spacedrelation with the outer surface of the spring roller 8. v f

In use, assuming that the parts have been assembled in themanner described to close the window frame by. the screen it is only necessary to engage the bar 12 and pull downwardly against the tension of the spring roller 8 whereupon the screening will be unwound from the roller 8 and will be guided `during this downward movement by the guides 13. 0f .course when the bar ispositioned near the silleof the frame downward movement may be stopped to allow the spring roller to stop as is the custom in usual window shades and by reason of the fact that this bar is arranged against the sill and vthe sides ofthe screening 11 are arranged in close relation with the guides 13 it will be appreciated that insects will be prevented from ssing intol the room or other inclosure.

it is only necessary to fasten the bar l2 to give it a slight jerk whereupon owing to the tension of the spring roller the screening will be automatically rewound and during this action the guide roller 15 will serve to prevent spreading thereof.

As' many changes could be made in the above construction and many apparently widely different embodiments of this invention could 'be made without departing from the scope of the invention, it is intended that all matter contained in the above `description or shown in the accompanying drawings shall be interpreted as illustrative and not 'in a limited sense. It is also to be understood that the language used in the following claim is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention, which as a matter of language, milght be said to fall therebetween.

aving thus fully described this invention,

what is claimed as new and desired to be secured by Letters-Patent, is z-n the lower edge of the plate and the sill of the frame for guiding the movement of the iece of screen and for coperating therewit in preventlng the passage of insects through the frame, an elongated transverse bar carried by the outer end of the piece of screening and operating between the guides to serve dual for the purpose of acting as a weight to hold the piece of screening taut when in an extended position and for coperating with the sill of the frame for preventing the passage of insects through the frame, and a guide roller mounted between the plates and Y coperating with the screening for preventing the same from spreading during actuation.

In testimony whereof I ax my signature.
