F is a ratchet-toothed wheel on the disk d. This wheel is preferably arranged next to the end of the roller, and f is a pawl which is pivoted to the bracket and which engages with the said wheel. This pawl is held in engagement with the wheel by a spring f but this spring may be omitted, if desired. The tension of the roller-spring is adjusted by means of an ordinary key or wrench applied to the To all whom, it may concern,.-

Be it known that I, WILLIAM F. CUM- M1NGs,'a citizen of the United States, residing at Plattsburg, in the county of Clin/ton and State of New York, have'invented certain new and-useful Improvements in Window-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window-screens for use in preventing flies from entering dwelling-houses, and it consists in the novel construction and combination of the parts hereinafter fully described 4and jclaimed.

In the drawings, Figure l is a front view of the screen applied to a window with. a portion of its casing broken away. Fig. 2 is a section through the screen, taken on the line x x in Fig. l. The remaining figures are drawn to a larger scale. Fig. 3 is a front View, Fig. 4 is a plan view, and Fior. 5 is a rear view, of a portion of the top bar of the screen. Fig. 6 is a cross-section taken on the line y in Fig. 5. Fig. 7 is a front view of a portion of the roller. Fig. 8 is a cross-section takenv on the line e 2 in Fig. 7. Fig. 9 is a side view of one of the roller-brackets, showing the ratchet-wheel and pawl. A

A is a portion of a window-frame of any approved construction, and b is the windowe sill.

B is a portion of the lower window-sash, which slides in the window-frame in the usual manner.

C is a roller which is journaled in suitable bearings at the lower part of the windowand close above the window-sill. This roller is a spring-actuated roller of any approved construction,'such as used for window-curtains, and it may be made in one pieceor in extensible sections.

Dis a rectangular shaft which projects at one end of the roller andwhich engages with a disk d, which is journaled in a bearing-plate d', secured in a recess in one of the brackets E at the side of the window-frame. The other end portion of the shaft D is operatively connected with the spring of the roller.

The brackets E are secured to the faces of the sash-guides or Weight-boxes of the frame, so that spaces c are formed between the brackets and the side portions of the frame ttl) give access to the ends of the roller-spind e.

shaft D.

ric which will keep out flies. wound upon and secured at its the roller C. j

H is a bar at the top edge of the screen G. The top edge of the screen is inclosed between a channel-shaped metallic strip r, and this strip and the edge of the screen are nailed or otherwise secured to the said bar.

I represents two tabs of flexible material secured to the said bar and affording a means lower edge to the window-sash. The `lower part of the window-sash has the tabs connected toit by pins i.

In order that the screen may be readily applied to windows ofdifferent size, the screen, its roller, and the top bar are all preferably made in sections, so that they maybe extended. The main section of the roller C is provided with a series of longitudinal extensible section C of the roller is provided with longitudinal projections j, which are Each section of the roller is preferably provided with four projections, and the diameter of the roller at the projections is preferably a little less than the diameter of the main section of the roller, so that the overlapping portions of the sections of the screen may slide in contact with each other without too much friction. of the Wire screen, which is secured to the extensible section C of the roller.

section H', to which the section G/ of the screen is secured. The main portion H of the bar is provided with a longitudinal projection at its upper edge, and the main part G of the screen is secured along the upper edge of the bar H and its projection 7i. The extensible section H of the bar is provided with a projection h at its lower edge, which slides under the projection h. The lower edge of the section H projecting rectangular end portion of the.

G is a wire screen or any other screen fab-l Tlns screen 1s of securing the upper edge of the screen to.

projections J, and the.

slidable between the said projections J.V

G is the extensible section IOO The bar H is provided with an extensible I IIO I and its projection 7L are cut away to form a space lc, in which the upper edge of the screen-section G is secured, so that the said screen-section may slide freely behind the main portion of the screen.

The main portion of the bar is provided with a back piece N, which is rigidly secured to it and which is provided with a slot n at one end. The section H of the bar is provided with a back piece N, which is rigidly Io secured to it and which is provided with a projecting tongue which is slidable in the slot n. The tongue n is arranged at the middle part of the end of the back piece, and it comes over the crack or space between the projections h and h. The back pieces stiffen the bar and enable it to be extended in a satisfactory manner.

The side edges of the screen are slidable in grooved guides P, whichare secured to the 2o brackets E and arranged against the windowframe. S is a casing secured to the said brackets in front of the roller G.

In order to prevent flies from j assing under the roller, the casing is provide with a guide s, and t is a packing-piece which is slidable in the said guide. This packing-piece is preferably arranged at a tangent to the rolled screen and is provided with a beveled edge t', which presses against the wire screen.

3o Springs s maybe applied behind the packingpiece to hold it in contact with the rolled screen. ing-piece with very little Jfriction as it winds upon the roller, because of the inclination of the said packing-piece with respect to the roller.

T is a stiffening-ring of thin metal which is secured over the projections of the roller-sections. This ring is secured to one section, so

4o that the projections of the other section may slide freely.

The screen fabric is nailed to the .rollersection C on each side of the ring T and overlaps the said ring. This ring is formed of very thin sheet metal, and it does not materially increase the diameter of the roller-section.

The screen pushes back the packj What I claim is- Y l. In a window-screen, the combination, with a bar-section H having a projection h 5o at its upper edge, of a bar-section H having a projection h at.its lower edge which slides under the projection h, a screen-section secured to the lower part of the bar-section H and its projection h, and a screen-section se- 5 5 cured to the upper part of the bar-section H and its projection h and overlapping the aforesaid screen-section.

2. In a window-screen, the combination, with a bar-section H having a projection h 6o at its upper edge, of a bar-section H having a projection h at its lower edge which slides under the said projection h, the said projection h and the lower part of the bar-section being of less width than the bar-section H 6 5 and its projection h, and the backs of thesaid parts being arranged flush with each other, a screenesection secured to the lower part of the bar-section H and its projection h, and a screen-section secured to the upper part of 7o the bar-section H and its projection h and overlapping the aforesaid screen-section.

3. In a window-screen, the combination, with a bar-section H having a projection 7L at its upper edge, of a bar-section H having a projection ,h at its lower edge which slides under the projection h, a bar-section N secured to the back of the bar-section H and having a groove n in the middle part of one end portion, a bar-section N secured to the 8o backA of the bar-section H and having a tongue n which slides in the groove n over the adjacent portions of the said projections 7L and h', a screen-section secured to the lower part of the bar-section H and its projection 8 5 h', and a screen-section secured to the upper part of the bar-section H and its projection 7L and overlapping the aforesaid screen-section. In testimony whereof I have affixed my j signature in the presence of two witnesses. 9o l WILLIAM F. CUMMINGS.
