WINDOW SCREEN.

Application filed January 14,1925. Serial No. 2,380.

To {1f/Z vai/10712. t may concern.'

lle it known that LlilnNns'r l. GARNER, a citizen oit' the United States, residing at Charlotte, in the county ot' Mecklenburg and State oit North Carolina,'ha\*e invented new useful Improvements in lVindow Screens, ot which the following is a' specilication.

'lhis invention relates to window screens and particularly to frames vfor this class ofV devices,`and the primary object of the saine is to provide a comparatively simple forni otl screen frame having the various parts or members thereof so associated as to be strong and durable and also ellfective in operation.

A further object .ot the invention 'to provide means in connection with a window screen whereby the latter may be easily applied to. have vertical sliding.movementV and readily vremovalole lor the `purpose oli'v rep ai r. Y

lhe improved screen is provided with metal `strips or members applied over the wire gauze or screen covering and secured to wooden members comprising 'the body of the trame by screws or analogous easily removable.fastenings, the metal strips at the sides providing a neat finish and also contributing to theformation of grooves for engagement with the guide strips of the window traine, and (the metal strip at :the

bottom providing for a lower'rest means when the frame as a whole is lowered by extension thereof below the lower wooden strip oi the body of the frame. The cor- .ners of `the body frame of wood are materially strengthenedby a novelv construction which will be more fully hereinafter specilied. Y

The improved forni of screen trame is illustrated in the accompanying drawings,l

The improved window screen frame comprises upright side bars and upper and lower horizontal bars (3 and; The upper horizontal bar andthe upper ends of vthe sidel bars 5 are secured in a very novel niair' ner, each end ot the bar 6 having a series ot' slots or grooves 8 formedtherein to re'- ceive tongues 9 and l() of the side bar, the

innermost slot `or grove 8 opening through the inner side 'ot the bar Gand thelatter formed at the inner side with an outwardly projecting tongue ll, which' is materially longer than the tongues 9.l The stript is also formed at Iits upper end with air inner slot or seat 12, to receive the tongue 11 `in 'Hush relation thereto. The tongue 10 ot the strip 5 is of the same dimensions as the tongue l2, and when the ends ofthe bars 5 and G are interlitted to'iorni thecorner jointure, the tongues l0 and ll Aproject a double wall or thickness of material inwardly beyondv the terminals ot the tongues 9. The tongues 9,10 and*` 1l are tirinly secured by the application thereto of water# glue or analogous eeinentitious material, or otherwise secured as desired, and by the formation of the parts as just fexplaineth'a strong corner structure is provided. The corner or end v'connections-between the lower horizontal bar 7 and the side or upright bars 5 are also advantageous,

the bar l slots or grooves 14C opening through the lower end of the adjacent bar The slots or grooves 14E are oi such depth as to permit the tongues 13 to be moved'upwardly a at each end being formedV with tongues 13, whioliare fitted and securedfin4 considerable distance above the lower ends durable connection at the corners of the body members of the frame. By providing a number of tongues and grooves as specified, a greater surfacefor the application of glue is obtained andthe nails or pins will be more effective' in Vholding the corners when there is a strain on the frame. The tongues are so spaced that at least a portion thereof, or one at each corner, will pass the slot, groove or rabbet structure and reinforceV theinside edge or lip side of the screen and thereby render the said lipl less liable to split off and add materially Vto `the strength of the frame as a whole.

Applied over the body frame as just eX- plalined, and which is preferably made of wood, are side metal strips 16 and upper and lower metal strips 17 and 18. These metal strips are appliedto the outer sides of the body members of the frame and the side strips 16 have their edges bent outwardly at right angles, as at 19, to stiffen or reinforce the same, and the upper edge of the 'strip 17 is formed with an inwardly bent angular flange 20, which snugly fits over a portion of the upper kedge of the upper horizontal bar 6. The lower edge kof the top metal strip 17 bent outwardly at right angles, as at 21, to reinforce or stiffen the same, and the lower metal strip 18 has an upper outwardly bent right-angular stiffening iiange22 and a lower inwardly projecti ing right-angular flange 23 which forms a bottom rest to engage the sill and may be of varying width as found necessary. The lower ends of a portion of the downwardly projecting tongues 15 of the side bars 5 contact withv the opposite extremities of the ange23. These metal strips 16, 17 and 18 areapplied over the wire gauze 211, screws 25 being inserted at intervals, as shown by Fig. 2, to hold these strips in place and likewise to engage the wire gauze. It is preferred that the holes in the metal strips through .which the screws 25V extend be punched or formed after the strips are laid against or over the wire vgauze 24, so as to cause the kburrs formed by punchingthey metal to engage the wire gauze and be pressed into the wood of the bars ofthe body frame, to more securely hold the metal strips in place and also positively fasten the yraising and lowering the screen.

wire gauze, this incidental securing feature by formation of the burrs being particularly effective. At the sides of the screen frame th`e metal strips 16 project sidewise outwardly beyond the terminals of the slots or grooves 8 and tongues 9 and in line with theouter edges of the upright side bars 5, and by this means together with the provision of the projecting tongue structure 10 and 11, a reinforced groove means is provided at each side of the screen. The flange 20 projecting inwardly from the upper portion of the upper strip 17 covers the upper edge of the wire gauze and shields and hides the latter. The lower metal strip 18 with its bottom supporting flange 23 and its upper flange 22 forms a very ellicient reinforce structure at the bottom of the frame and also forms an inner opening for insertion of the lingers of an operator, and thereby efficient means is provided for conveniently The lower flange 23 may be bent in various shapes to conform to the surface contour of the window sill against which it is adapted to bear.v The outer metal side strips 16, forming one wall for each of the side grooves of the screen, are of material advantage in view of the yielding character or flexibility of the metal against themeans for guiding the screen when the latter is mounted in the window frame. Dampness will not in the least affect these metal strips forming outer wallsV for the grooves and there will be no liability of jamming or stretching of the screen on the guide means as is often the case with screens having all wood sides or side members. The upper and lower outer metal strips also add materially to the rigidity of the screen frame as a whole and provide for a more positive securement of the upper and lower edge portions of the wire gauze or screen fabric 24 than is possible by the use of wooden strips.

To facilitate the application of the screen to a window frame, the stops or guides 26 of the side members 27 of the frame are formed in two sections 28 and 28, which are respectively fixed and movable, joints being provided between the ends of the said sections, or each section 28 has longitudinal 'slots and tongues 29 at the upper end thereof, to receive spaced tongues 30 at'the lower end of each section 28a. Each section 28a is fastened at its upper extremity and is operable to swing outwardly after the lower tongues 30 have been separated or pulled out from the slots and tongues 29, said operation being accomplished by first pulling or pressing each section 28FL inwardly Iin a sidewise direction relatively to the window frame, as shown in dotted lines by Fig. 8. Owingpto the length of theupper sections 28, the sidewise inward bending or pressing stress exerted thereon vwill cause the said A j l'.

lso i sections to yield suiiiciently `to separate the same from the lower sections 28. After `the sections 28a have been separated as just explained and moved outwardly as shown in `full lines by Fig. 7, the screen frame is moved upwardly thereover far enough to clear the lower extremities of the sections 28 and the `said llatter sections are then pushed forwardly into normal position and the lower extremities of the sections Q8 bent inwardly in a sidewise direction, to assemble the ends of the same with the upper ends of the sections QS, and by this means the stops or guides 2G will be held in normal straight position and the screen will be free to move upwardly and downwardly thereover without obstruction Iin view of the close fitting of the jointed ends by means of the slots and tongues 29 and 30. At one side at least the upper' portion of one of the sections 28 has a friction spring 3l secured thereto for engagement by one side of the screen i'rame to hold the screen elevated when it is desired to have a clear opening through the lower portion of the window frame, or in the event it desired to close the lower sash and open the upper sash.

llt is not always necessary to use cementitions material or glue in securing the corner joints, as the tongues, slots or grooves have such a close fitting that they may be tightly held against loose movement or disjointure by nails, pins or other fastenings inserted therein.

The improved screen frame as a whole will be found exceptionally convenient and zulvantageous as compared to the ordinary well known screen constructions, and it is proposed to modify the proportions, dimensions and minor details of construction as desired and found necessary to adapt the improved screen structure to various sizes of window frames and sash.

wWhat is claimed as new is:

l. A screen frame comprising upper andv lower and side main frame members having corner joints comprising interfitted and secured tongues and slots, a part of the tongues being projected beyond the remaining portion of the tongues and providing reinforcing means and the side members of the frames also extending beyond the ends of the upper and lower members, a wire gauze covering applied to the main frame members, and metal strips removably applied over the wire gauze covering` and the one side of the main frame members and having flanged edges toreinforce the same, the side metal strips projecting outwardly beyond the ends of the upper and lower main frame members equally with the side members of the main frame to form grooves for engaging guide devices.
