To all whom t may concern.'

Be it known that I, CAssIUs M. PARsoN,

a citizen of the United States, residing at Kokomo, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

y invention relates to an improvement in window screens, and more articularly to that type of screen intended finir use by having the wire fabric thereof mounted upon a spring roller with the loose end attached to the window sash so that as the sash is moved the screen will be extended from or taken up by the spring roller.

An object of, my invention is to provide a structure of the character 'as set forth which is of such form and construction that the parts may be embodied in conjunction with the framing of a window as the window is being installed as new may be built into an old window.

nother object lies in providing a spring roller which 1s so formed that it partakes substantially of the character of the usual shade roller, but has no means forcatching to hold the roller against turning under the action of the spring, the parts being thus so arranged that as the window is either raised or lowered in a sliding path the spring of the roller will permit ready extension of the screenA or will take the same up properly.

Yet another object lies in providing means by which the roller is held against movement under the impulse of the spring during the installation in conjunction With a window, and in constructing means by which the roller will be removably held in place but may be positively secured to be retained against accidental or casual displacement.

Vith the above and other objects in view, my invention consists in certain novel features of construction and combinations of parts which will be hereinafter set forth in connection with the drawings and then more particularly pointed out in the claims.

In the drawings Figure 1 is a View in elevation showing a Window with my invention applied thereon.

Fig. 2 is a vertical the line 2-2 of Fig. 1. v

Fig. 3 is a view showing the springroller and with the arts illustrated in sectlon.

Fig. 4 is a fi'agmentary view taken on the line 4 4 of Fig. 3.

Fig. 5 is a detail work, or the parts,

sectional view taken on view in section taken on the line 5-5 of Fig. 3.

Fig. 6 is a detail view showing a modification which might ber-resorted to in the construction of the spring roller mounting. v

- The window frame which is formed to embody the side casing members 1 and 2 with the lintel 3 and sill 4 connected therewith is substantially of standard form and has the upper and lower sashes 5 and 6 mounted therein to be capable of sliding movement. To all intents and purposes, these parts are of usual construction, but in the roughing in of the framing around the window, clearance is to be left above the lintel and below the sill.

The lintel is slotted through as shown at 7, adjacent to the outer edge of the upper sash, and the sill 1 has a similar slot 8 provided adjacent to the inner side of the lower sash. Roller supporting brackets 9 and 10 are mounted at the sides of the frame adjacent to the slotted openings 7 and 8, by being secured on the side casing members 1 and 2 if desired, and these supporting brackets are made of substantially the type now ordinarily used for shade rollers, the one being provided with a substantially circular orifice and the remaining ing anotch formed therein, after the manner shown at 11 in Fig. 4.

Spring rollers 12 and 13 are mounted in these brackets 9 and 10 to extend across above the lintel 3 and below the sill 4, and to lie'in parallelism with the openings 7 and 8. These spring rollers 12 and`13, which are substantially duplicates, comprise the wood, metal, or other cylindrical body portion l1 cored out or otherwise shaped at one end to provide the socket or opening 15. At the opposite end of the body 14, a bearing pintle 16 is secured by being driven into the body, or in any other manner, this bearing pintle being of substantially cylindrical form so that it may be inserted in the circular opening of the one supporting bracket and will turn freely therein. A block 17, which has a bearing provided therein for the spring mandrel 18 is shaped to be received in the bore or opening 15, and a pin 18 is provided to hold this block against turning Within the opening. A coil spring 19 is connected at one of its ends with a block 17 and after being wound around the mandrel 18 to substantially the bracket of each pair havv outer 0nd thereof is secured 110 ybrackets 10. This fitting of the flat sided portion of the mandrel within the notch 11 will mount the mandrel to be held against turning movement with respect to the supporting bracket, and thus the sprlng 19 has full control over the roller body. To secure the mandrel 18 against displacement from the notchvll, a-substantially hooked shaped member 22 is carried on the supporting bracket 10 .to be brought down over they mandrel after the same has been moved to occupy a position at the bottom of the notch 11.

The rollers 12 and 13 have the wire mesh or other screen strips 23 and 24 connected thereon and then wrapped around the rollers, and at their free `ends these screen strips are connected with the upper and lower sashes respectively, it of course being under- Stood that the connection will be made with the top and bottom rails of these sashes. The screen strips are extended through the slots 7 and 8 previous to securement to the sashes and to insure that the fabric will not pull out, reinforcing strips 25 may be placed over the connected edges as the screen strips are attached to the upper and lower sashes.

The parts can be assembled when the window is being built by mounting the supporting brackets 9 and 10 in the proper relations before the frame is set in place, and then placing the rollers 12 and 13 in their proper positions before application of the interlor trim, it of course being understood that the sashes must be first fitted to work properly before the screen strips are brought through the slots 7 and 8 and are connected therewith. lVhile the rollers 12 and 13 are being fitted in place, it will be desirable to mainf tain the springs 19 in a partially wound condition, and as no catch means is provided, the parts .as illustrated in Fig. 5 might be employed. As is here shown, the mandrel 18 is provided with a transversely extending bore 26 and a short length of,w1re 27 is inserted in this bore 26 and is then brought around and fastened in the opening 28 in the cover plate 20, this length of wire thus securing the mandrel against turning movement under the impulse of the spring 19 after the mandrel has been turned to store up energy in the spring.

Where the screen structur'eis to be fitted to a window already built in, and even in as some instances where windows are being newly placed, it may be awkward to apply the bracket portions 9 and 10 in the manner as above set forth, and-therefore under these circumstances the supporting brackets can be formed after the manner shown in Fig. 6 with the supporting and attaching base thereof bent substantiall f at right angles to the main extent. The brackets 29 are then secured at the proper points upon a supporting base strip 30, which is made of comparatively narrow width and which may thus be inserted through a slot left or cut through the lintel and the sill. Following the insertion of the parts, the cut away portion can be inserted in place and then screws can be used to secure the supporting base bar 30 in the proper mounting, it of course being understood that the screws will be passed through from the outer side of the lintel or sill to draw the base portion 30 tightly y thereagainst.

From the foregoing it will be seen that a screen structure is provided which disposes the screen portion in such relation that when the windows are closed, the screen strips are entirely concealed, and as either sash is moved, the screen strip carried thereby is brought to cover over the opening as left by the shifting of the sash, that the parts as described may be fitted in conjunction with a window as the saine is built in or may beapplied to windows already in place without material alteration and without destruction to the standing woodwork or trim of the window, and that the rollers as provided are at all times positively maintained in the proper relation and operate to let out and take up the screen strips to insure that the same will be tightly stretched over the opening at all times while at the same time the movement of the sashes will not be interfered with except in so far as the force of the spring is concerned; and, that the arrangement-of the parts in the manner as set forth is such that when the sashes are brought to the closed position, the screen strips will be rolled smoothly upon the rolls to thus be maintained against bulging or uneven stretching and will be protected from the Weather.

The sash may have window lifts 31 secured thereon to aid in the raising and lowering, and if desired a strip 32, which may be of felt, rubber fabric, or other suitable material can be secured on one of the sash to form a stop as the two sash are brought to intermediate position, it being preferable that this strip be secured on the lower side of the bottom rail of the upper sash as in this mounting the strips 32 will exclude iies or other insects from finding their way up between the two sashes. It will of course be understood that the screen strips 23 and 24 are to lit over at their edges rather snugly against the side casing portions 1 and 2, and

nasceva thus tiies and other insects will be excluded at these points.

lli/while in the foregoing l have shown and described only specific forms of construction, it will be understood that this structure might be adapted for use in hospitals and in other places by having fabric inserted in place of the screen strips to thus permit passage of air but to cut oil' strong currents of air or draft, and that a number of other changes and modifications might be resorted to in the torm and arrangement of the sev eral parts as in the manner of application, without departing from the spirit and scope of my invention and in view of this tact l do not wish to be limited to the exact disclosure but only to such points as may be set forth. in the claims.
