Patented Dec. 10, 1929 PATENT OFFICE JAMES WATSON, on MARINETTE, WISCONSIN WINDOW SCREEN Application filed May 23, 1927. Serial No. 193,550. I

This invention aims to provide novel means for connecting a screen to a slidable Window sash, so that the screen may move with the sash, when it is desired to have the screen in 5 position, the construction being such that the sash may be operated without the screen, when desired, the screen then being housed in an out of the way position within the window frame. V

Other objects will be made manifest as the description proceeds, and it is to be under stood that a mechanic, working within the scope of what is claimed, may make such changes as his skill may suggest,'without departing from the spirit of the invention.

The invention is shown in the drawings, as applied to a window which consistsof a single vertical sliding sash, but it is to be understood that the invention may be embodied, as well, in a two-sash window, the change being merely one of duplication, and calling for no specific illustration.

The window frame is marked by the numeral 1 and includes stiles 2 connected by a sill .3 carrying a table 11. Guide strips 1 and 5 When the screen 12 is not in use, it is lowered,

extend upwardly from the sill 8 and are mounted on the stiles 2. Guide grooves 6 are formed in the stiles 2, between the guide strips 4 and 5, the grooves 6 extending both upwardly and downwardly with respect to the sill 3; At a point well above thesill 3, the guide grooves 6 have transverse extensions 7 the utility of which will be made manifest hereinafter. A slot 8 is formed in the sill, in the same plane with the guide grooves 6. A plate 9, preferably made of metal, is secured to the sill 3, and has an upstanding rib 10.

A screen, marked generally by the numeral 12, is mounted to slide in the guide grooves 6.

as indicated in Figures 1 and 2, andlies below the sill 3. The screen slides through the slot 8 in the sill 8. The screen 12 is made up of a bottom rail 14, side rails 15, and a top rail 16, the rails being made ofmetal, and being connected together, and to the foraminous body 19 of the screen, in any desired manner, the edges of the body 19 of the screen being received within the rails 1 1, 15 and 16. The bottom rail 14 and the side rails 15 are u-shaped in transverse section, whereas the top rail 16 has side walls which are extended laterally to form a transverse flange 17, the flange 17 being connected to an upstanding bead 18which is U-shaped in transverse section. In the bead 18 is mounted a metal rod 20 which, for the sake of reinforcement, preferably is as long as the bead. Intermediate its ends, the rod 20 is supplied with a U-shaped keeper 21 which extends upwardly through the bead 18. As shown at 22 in Figure 1, the flange 17 and the bead 18 are cut-away at their ends, so that the flange 17 does not extend out quite to the outer edges of the side rails 15. As a result, the side rails 15 are mounted to slide in the guide grooves 6, but the ends of the flange 17 merely slide on the exposed surface of the stiles 2, and the guide grooves 6 are narrow enough so that the ends of the flange 17 cannot enter the grooves. When, however, the screen 12 is raised far enough, thescreen can be moved horizontally,

as shown by the arrow A in Figure 1, the ends of the flange 17 entering extensions 7 (Figure 2) at one side or the other of the window A sash 23 is slidable on the stiles2'oftheframe 1 between the guide strips: 41and: 51

The sash 23 includes a bottom rail 24 provided in its lower surface with a groove' 25 which is adapted to receive the rib 10 on the plate 9 to afford a tight closure when the sash- 23 is lowered upon the sill 3 as shown-in Figure 2. In the lower 'edge of the bottom rail 24'of the sash 23 there is a groove 26 which is adapted to receive the bead 18 on the screen 12, when the upper edge of the screen is coupled to the: lower edgeof thesash 23, by a means which will be. described hereinafter. In the vertical edges of the'sash 23 there are grooves 27'which are alined" with the grooves 6 of the stiles 2, as shown in Fig ure 7 Weather strips 28, preferably made offmetal, are mounted'in the grooves-27 of. the sash 23 and slide, in the grooves 6 of the stiles 2. The weather strips '28'preferably are U shaped in cross section, andhave a littleresiliency, so that they will tend to expand and have a good sliding lit in the grooves 6, without exertingtoo much drag when the sash 23 is raised and lowered. The strips 28'are' held in place by any desired number of'securing elements 29, such as pins, mounted in the sash 23 and passing through the weather strips 28. The guide strips'5foverlap the pins 29 at their outer ends. and, consequently, theisecuring elements 2'9cannot become detached accidentally, with a resulting. loosening of the weather strips 28: but. when the strips 5 are removed, then the pins 29 may be detached, and the-weather strips 28 pulled out.

This is done, generally, by raisinggthe sash 23 and reaching up into the'lower'ends of the strips 28 with a suitable tool (not shown) the tool beingreceivedin theholesformerl'y occupied by oneof thepins'29, and the'weather strips then bein'gpulled'down'and out of en'- gagement with the sash 23.

. A seat 30, which may be an anger hole, is formed inthe lower edge of'the' bottom rail 24 of the sash 23, and in the seat 30 is located a latch casing 31 which is T-shap'ed in cross section, the casing-being provided with a'foot plate 32,.which is countersunk into and'secured to the bottom rail'24 of thesash 23. Considered as to cross section, the latchcasing 31 comprises a body 33 and a troughshaped latch housing 34 disposed at" right angles to'the body and communicating with the body. Near to itsupp'er end, thelatoh casing 31, has openings 35 and 36' which are disposed opposite to each other, asindicat'ed in Figure 5. A latch 37 is'locate'd fon the most part in the housing 34 and is mounted to swing on a pivot element 38 carried by the part 34. At its lower end, the latch 37 is beveled as shown at 39, the latch being supplied with a shoulder 40 disposed above the beveled portion 39. A spring tongue 41 is secured at one end to'the latch'37,,the lower end of the springtongue 41 bearingslidably against the outer portion of the latch housing' 34p The functiongof the spring 41 is to swing the lower end of the latch 37 inwardly, into'the position shown in Figure 5, so that when the keeper 21 on the screen 12 enters the lower end oftheb'ody 33 of the latch casing 31, the keeper will first engage the inclined e'dge'39 ofthe latch 37 and tilt thelatch, and then. engage with theshoulder'40, as shown in'Figurefi, the construction'beingsuch that when the'sash 23 is raisedand lowered, the

screen 12 will;be raised and lowered also. i

a" wear plate 45 mounted I on" the bottom rail 24 of the sash 23 above the'lifting'p'iece46'. When the knob 44 is mounted on the finger 42, as'in Figure 5,'thelatoh 37 is" operated by pushing on the button-44,- to disengage'the shoulder 40 from thekeeper 21, whereupon the sash 23 may be raised and lowered independently of the screen=12, the screen remainingin concealed position below the' sill 3, as shownin Figured.

Sometimes it may be desirable to-operate the latch 37 by. pull rather than by push, and,

then, the knob 44 is detached from the finger 42 and is threaded onthe finger 43, the knob moving in the opening 35'.

The operation of the-device has been-dealt with hereinbefore, step by step, in connection with the structure, but, generally stated, the screen 12 maybe raised' and lowered along with the sash 23, because these parts/are connected through the instrumentality of the latch mechanism shown'in detailinFig. 5; but if the operatorwvishes' to raise and lower the sash 23, leavingthe screen 12 in the concealed position ofFigure 1, hemay do this by tilting the latch 37 so as tofree it 'fromthe keeper 21 on the screen 12.

Some persons may prefer a: superficial latch casingto' theonethat' is mounted in the bore-or'seat 30, as shown inFigure '5'. A Under such circumstances, recourse is had to the structures'shown in Figures 8 and-9. Inthis formof'the invention, parts hereinbefore de seribed have been designated: by numerals previously used, with the s'ufliX a. The latch housing 34 and thebody 33 'of the easing 31 are made separate, and have flanges leti mounted in a shallow recess 47 in the sash 23 and held therein by securing elements 48, such as screws.

What is claimed is In a device of the class described, a Window frame provided ateach side With stiles having guide grooves, each groove having a transverse extension, a screen slidable vertically in the grooves and including a transverse flange Which is long enough so that both of its ends can engage With the exposed surfaces of the stiles at both sides of the Window frame to prevent the screen from moving horizontally in the grooves and'disengaging the vertical edges of the closure from the grooves,'each end of the flange being so shaped as to be received in the aforesaid extension, thereby to permit a horizontal movement ofthe screen in the frame and a disengagement of the vertical edges of the screen from the grooves, the grooves and the extension being extended but part Way through the stiles.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature.

JAMES WATSON.
