HINGE FOR SLIDING WINDOW SCREENS Filed March 9, 1925 y @QW Patented Sept.'` 17, 1929 UNITED STATES HINGE FOR SLIDING WINDOW SCREENS Application led March 9, 1925.' Serial No. 14,288.

One of the objections to the sliding window screen as now most commonly employed is that it is necessary to bodily remove the screen from its slides whenever it is desired to Wash the windows. Itis more or less diflicult to do this by reason of the weight of the screen, and frequently the screen becomes overbalanced and falls to the ground which results in damage to the screen.

The object of my invention is to provide a combined sliding and hinge screen which may be easily installed and is of such construction that the cost will not materially eX- ceed the cost of the ordinary commonly use-d screen.

Another object of my invention is to pron vide in the place of the usual blind stops channel blind stops which serve the dual capacity of blind stops and slideways for the screen. n

A further object of my invention is to provide for use with the channel blind stops a screen frame having hinges, one leaf of which is adapted to interlock with a slide in the said channel blind stops; and with these and other objects in view, my invention consists of the parts and combination of parts as will be hereinafter more fully set forth.

In the drawings:

Figure 1 is a front elevation of a window frame and its sash ywith my improved screen mounted in said frame, the screen being shown in closed position.

Figure 2 is an enlarged detail perspectivey view of one of the side members of a window frame showing the'installation of my invention thereto. f

Figure 3 is a sectional view through the lower portion of Figure 1.

Figure l is a perspective view ofmy improved hinge.

Figure 5 is an enlarged ydetail view.

Figure 6 is a perspective view of one of the slide pins.

Figure 7 is a perspective view of the face plate for said slide pins.

The reference numeral 1 designates a window frame having the side members 2 and 3 and sill 4, all of which may be of the usual construction with the exception that I do not emplo the usual solid blind stops, but us'eiii place t ereof the blind stops and 6 construct-A f f ed of channel metal as clearly shown in Fig; ures 2 and 3. The blind stops are secured to the Window'frame by means of the screws, ory other securing devices 7. f f 1 1 i,

The blind rstop y5, as more clearly shown in Figure 3, is provided with an inwardly later.- ally extending flange 8 at the free edge of which. there is an inwardly extending fiange), theseflanges constitutingin effect a substantially L-shape flange, which term I may use in the claim for the sake of clearness and brevity. The blind stopy 10 has one long arm or side member 11, which extension ofthe arm funct tions `as a guard covering the joint between d the, blind stop and thehinge side ofthe screen 12, as more clearly shown in k,Figure 3. c i

At predetermined intervals in the rblind stop 10 I secure channel sections 13 and 14 l .the outer free edges ofthe side members of whichy are kbent inwardly at right angles to provide overhang flanges 15. These sectional channel' members may be secured in any suitable manner within the blind stop 10.` The channel section 13 is provided with a stopy 16y f to be hereinafter referred to. y vThe screen 12r is provided on one ofrits hanging stiles, the hinge 17, the leaf ,'18 ,of which is provided at each end witha liange 19 bent` inwardly at right angles to the leaf 18, said flanges 19 having recesses 2() in each end thereof. The flanges 19 may be described as substantially T shaped;

With `the hinges 17 secured to the screen 12 the screen is positioned with the hinge' leaves 18 abovethe kupper edges of the chanf nel sections 13 and 14 whereupon the flanges y19 ofthe hinge leaf 18 are free to'be pro jected withinthe blind stop Gwhereuponfthe y downward kmovement of the screen causes the flanges 19 to movewithin the channelsections f y13and lll, the flanges 15` of the channel sections 13 andf14 interlocking in the recess 20 of theflanges 19 therebysecurely interlocking` the hinges in position within the blind I screen 12 from binding on the window sill 4 I provide the stop 16 which is so positioned as to hold the screen in the proper position relative to the window sill 4, as will be readily understood. In order to prevent the hinge leaves 17 and 18 from assuming intimate contact relation when the screen is in its closed position I provide a stop 21 projecting above the tace ot the hinge leaf 17 and have shown this stop as being integral with one of the screws to secure the leaf 17 to the screen frame.

On the other, or swinging side of the screen I provide slidable pins 22 (preferably two in number) slidably mounted in the side stile of the screen and adapted'aspshown in Figure 3, tobe projected Vwithin the blind stop 5. This pin is provided with a lock element 23 which,'as shown in Figure 3, will lock the pin 22 i-n-'its operative position byreason ot the fact that in that posit-ion the lock member 23 is at right angles to the slot 24 of the face -plate 25, which face plate is secured to the side 'stile of the screen. This pin 22, as shown inthe drawing, is provided with a suitable hand hold, as shown.

Now `with 'the parts yin the position shown in Figure 2 andin the sectional view of Figure 3 `the screen is in its position relative to the window frame in which it may be swung outwardly on its hinges, after the bolts or pins y22 are withdrawn from the blind stop :5.` With the parts as shown in Figures l and 'the screen is in position to be slid in the blind stops 5 and 6, and in order to hold the screen in the position at the top of the window lframe I provide friction springs 26 which are'secured in the bottom of the blind stop 5, said springs not only holding the screen' across the upperportion of the window frame, but also exert the pressure in the direction of the hinged side ot the screen therebyinsuring the'hinge in its proper seating and sliding action.

'It will be understood that changes may be made in "the details of constructiony shown without departing from the scope of the appended claim.

What I claims is:

In a window, a'channel blind stop, a channel section secured in said stop and having its outer edges bent inwardly toward each other, a hinge one 'leaf of which is provided with an inwardly bent yliange at each end, a recess in each flange'adapted to receive the outer bent edges of the channel section and thereby lock the hinge on the blind stop.

In testimony whereof I aiix my signature.

CHARLES F. GEsoHroKrEn.
