In the accompanying drawings in which is il- '7 lustrated the preferred embodiment ot the invention 1 designates a window screen consisting of a single sheet o! screen or other exible material extending from the top to the bottom ot a u window trame 2 and arranged outside ot the window so'as not to interfere with the raising and lowering of the window sash and the ventilation aorded by the adjustment of the same. The window screen is provided at the top with a pair ot sheet metal screen clamping bars 3 and 4 extending across thek window screen at thetop there. of and clamping the upper marginal portion o! the window screen between them and forming a stift upper marginal portion for the window screen.

The screen clamping bars are provided at intervals with triangular lugs 5 formed integral with the bars by partially severing the metal. The formation of the triangular lugs provides triangular openings 6 and the said lugs extend from the inner faces 'of the bars 3 and 4 which are iitted nat against the upper marginal portion of the window screen. The lugs pierce the screen material and the triangular lugs o! the bar 3 extend through' the triangular openings o! the bar 4- and the triangular lugs of the bar 4 extend through the triangular openings of the bar 3. By this arrangement the lugs of both o! the bars pierce the screen material and the lugs ci each bar extend through the openings ot the other har.

Thelugs oi' the bar 3 are swaged or bent down over v the openings of thebar4and the lugsotthebar4 are bent downwardly over the openings oi' the' bar 3, the swaging and bending operations operating to enlarge slightly the lugs so that the latter cover and conceal the openings and are ei- A no g - material and into a recess l0 formed in the end portion of the bar 3. The lugs 7 and 9 are rectangular .and cooperate with the triangular lugs in interlocking the screen clamping bars and in securing the said bars to the screen material. The clamping plate 4 has its lower edge deflected slightly. as at 4' to effect a tight binding action on the screen or flexible material 1 along the lower edges of the bars 3 and 4.

The bar 3 is provided at its upper edge with a combined stiffening and attaching ilange A11 extending outwardly in a horizontal direction over the upper edge of the bar 4 and adapted to engage with catches 12 of bracket plates 13. Bracket plates 13 which are approximately rectangular are disposed horizontally and are provided at their inner ends with spaced projecting prongs 14 which are adapted to be driven into the window frame, as clearly illustrated in Fig. 2 of the drawings, whereby the bracket plate is supported in position with the catch 12 depending therefrom. The catch 12 which is formed integral with the plate by partially severing a portion of the metal thereof consists of a curved hook which extends downwardly and inwardly from the lower face of the bracket plate 13. The curved hook-shaped catch 12 engages under the projecting flange 11 which fits between the catch and the plate.

The plate 13 is driven into the window frame at the top thereof and is held against outward displacement by means of a fastening device 15 extending through a perforation 16 in the outer portion of the plate and embedded inthe top of the window frame. The fastening device preferably consists of a screw and is adapted to be readilyy inserted after the bracket plates have been driven into the window frame.

The flange ll at the top ofthe screen is now inserted between the catches l2 and the plate `13 by a rocking movement, that is to say, by disposing the screen on an outward downward inclined plane so as to pass the free edge of the flange 1l of the clamping bar 3 between the plates 13 and the catches 12 when the screen is swung inwardly to thereby introduce the flange 11 into the space between plates 13 and the catches forl a ready removal of the top of the screen from such position when desired, therebyv providing for a ready attachment and detachment of the upper edge of the screen from its supported position. Thus the screen may be secured and supported at its top and detached without removing iastenings of any kind.

The window screen is provided at the bottom with screen clamping bars 17 and 18 fitted flat against the screen material and constructed substantallj.-1 the same as the screen clamping bars 3 and 4 at the top of the window screen. The bars 17 and l8are provided with triangular lugs 19 constructed and arranged similar to the triangular lugs heretofore described. Also the ends of the bars 1'7 and 18 are provided with horizontal rectangular lugs 20 and cooperating recesses 2l. The screen material is extended beyond the lower screen clamping bars to form a flexibleflap 22 which is provided with a metal binding 23. The flexible flap is adapted to fit against the bottom or sill portion of the window frame and it provides a fly and insect tight connection and at the same time permits an adjustment of the window screen by lower fastening means for securing the bottom of the window screen to the sillor bottom portion of the window frame. The flap 22 may be any suitable flexible material and attached to the lower clamping bars instead of extending the screen fabric beyond the lower clamping bars and I will rely upon appended claims to cover such structure. This will enable the window screen to be drawn as tightly as desired and to be adjusted to fit windows where there is a slight variation in the size of the window.

The lower screen vclamping bars extend entirely across the window screen and the latter is flexible between the upper and lower clamping bars and is adapted to be rolled up into compact form for shipping, storing or otherwise handling the window screen. The inner and outer clamping bars are provided with horizontal inwardly extending flanges 24 which are adapted to stiien the clamping bars at the bottom of the window screen, and at the same time crimp and securely clamp the screen.

The bottom of the window screen is secured to the window sill by means of cam actuated hooks 25 mounted on cams or eccentrica 26 and engaging eyes 27 or other suitable cooperating f means mounted on the bottom sill portion of the window frame. Each hook 25 is provided with a horizontal engaging portion 28 having a recess 29 at the inner portion thereof to provide a seat for the engaged portion of the eye 27. The shank 30 of the hook 25 is enlarged and provided with a circular opening 3l which receives a cam or eccentric 26 consisting of a disk provided with a slot 33 extending across the disk and terminating short of the periphery thereof and adapted to receive an arm 34 of an operating member 35 angularly bent intermediate of its ends in opposite directions to form an intermediate pivot portion 36, the inner attaching arm. 34 and the outer operating arm. The inner arm 34 is fitted in the slot 33 and the metal of the disk is swaged at opposite sides of the slot to securely retain the arm 34 therein. Thevpivot portion 36 of the operating member is arranged in a bearing opening 37 of a casing 38 of approximately segmental shape struck up from the metal of the inner lower screen clamping bar 17 and severed at the lower edge from the said bar to form an opening 39 for the passage of the cam actuated hook 25.

When the operating arm 35 is swung upwardly or downwardly the cam is partially rotated and the hook is moved upwardly or downwardly according to the direction of the rotation of the carn or eccentric 26. The shank of the hook and the cam are held between the casing and the screen material which is clamped between the bars 1'7 and 18. The adjustment of the cam actuated hooks enables the screen to be maintained in a tightly stretched condition which is not affected by slight variations in the length of windows and the flexible flap 22 which extends downwardly and outwardly beyond the lower edges of the bars 17 and 18 fits against the window sill or bottom portion of the window frame and maintains a fly and insect tight closure at the bottom of the window.

The window screen which is adapted to be readily applied to and removed from a window frame is exible between the top and bottom portions nevasso- 'i 3 window mme to :om a. ny audimat tiene een;

and is adapted to be rolled up into compact form for shipping, storing, carrying and the like. Also the window screen is adapted to be applied to a window by any ordinary workman and does not require the services of a skilled mechanic o! .necessitate any alteration in the construction of the window frame.

Instead of the usual wire screen material. there may be substituted other transparent material, such for instance as thin sheets of flexible glass or other flexible material for use in cold weather or in times of storm 'and without changing other features of the invention and without interfering with application of the invention to va window frame and yet permit rolling of the material for storage or shipping purposes. In fact, the interstices of the wire mesh or fabric may be lled with suitable material whereby to prevent passage of air currents through the screen and yet notdestroy thel exibllityofv the wire fabric.

In Fig. l0 of the drawings is. illustrated another form of top fastening means which comprises bracket plates 40 each having an outwardly extending or outturned depending hook 41 which is engaged by an approximately hook-shaped or U-shaped flange 42 formed integral with an outer screen clamping plate 43. The bracket plate 40 which is similar to the bracket plates heretofore described and which is secured to the top of the p window frame in the same manner has the depending outwardly extending hook formed intel gral with it. The bracket plate is also provided of the opening or mouth ci' the hook 41.

fifi

with aresilient lug 44 formed by partially severing the metal of the bracket plate, as clearly illustrated in Fig. 15 of the drawings, and forming a protuberance which projects downwardly in front The resilient lug 44 is preferably curved as shown and when the substantially inverted hook-shaped or L-shaped flange 42 is engaged with the hook 41 the resilient lug extends downwardly below the top of the engaging portion of the flange 42 and connes the latter in engagement with the hook 41. The flange 42 may be bent or slightly distorted to swing it into engagement with a hook 4l and when it is designed to detach the screen the resilient lugs may be readily lifted by the plate of a 1 screw driver to permit easy removal of the flange 42 from the hook 4l of the bracket plates. The bracket plate 40 is provided with prongs 45 similar to the prongs 14 of the bracket plate i3 and the outer portion of the bracket plate is provided with a perforation 46 for the reception of a suitable fastening device 47 for retaining the bracket plate in engagement with the window frame.

The screen clamping plate 43 which extends transversely di the top of the screen cooperates with an inner screen clamping plate 48 and has its lower edge -49 slightly deflected inwardly to engage the screen 50 to form a tight binding or clamping engagement with the said screen 50 as clearly illustrated in Fig. 10 of the drawings.

In Fig. 11 of the drawings is illustrated another form of bottom fastening means comprising inner and outer transversely disposed screen clamping bars 51 and 52 secured together in clamping engagement with the screen 53 by lugs 54 constructed and arranged similar to the triangular lugs heretofore described. The outer plate 52 has its upper edge 55 preferably deflected inwardly to form a tight binding or clamping engagement with the screen 53 and the screen is extended below the clamping plates to form a flexible flange 56 which engages the window sill or bottom of the nection.

The inner transverse screen clamping plate is provided at its upper and lower edges with horizontsl anges 57 having vertically aligned openings for the shank .or stem 58 of a hook 594 which engages an eye 6o of the sill or bottom of the window frame. 'Ihe stem 58 is provided at its upper end with an operating handle 6l and a coiled spring 62 which is disposed on the stem 58 maintains the hook 59 tightly in engagementwith the ye 50 and confines the eye 60 in 'sisch engagemen The eye is confined between the bill of the hook and the bottom flange 57. The spring 62 has its lower end bearing against the bottom nenge and the upper end of the spring is connected with the stem preferably by being arranged in aperforation thereof, as clearly shown in Fig. il; The

spring permits the hook to be readily disengaged from the eye when it is desired to unfasten the the upper edge of the platel 64 and is bent to form an approximately horizontally disposed U-shaped or channel flange 65 in which. is `clamped or crimped the lower edge 66 of ascen''l whereby I the screen is securely connected Ato the lower transverse plates. The transverse plates are rela.-

tively slidable in a vertical direction and the outer i .transverse plate is provided at rthe bottom with an inwardly extending fiangee which fits hat' vagainst the window sill and which is engaged by a keeper 69. The keepers which may be of any desired. number each consist of a plate secured to the sill bya screw 'I0 or other suitable fastening iis' device and provided between its ends with a. bend forming an upwardly offset hook-shaped portion 'Il which engages over the flange 68 and which is i. maintained in clamping engagement with thesame by e. cam '72 mounted on one of the bottom transverse plates and engaging the other lbottom transverse plate and adapted to tension the screen f and at' the Vsame time cause a. tight 'enzasement f 73 of the plate 64 is mounted on a. pivot Hand between the' keeper andthe flange 68.

The cem I2 which operates in an arcuate slot is provided with s flange or head '15 which nts against the plate 64 at the outer fecey thereof. i i

iso

The head T5 is of greater width than the arcuate slot "or opening '13 and mounted on the pivot 'I4 is a washer 'l6 conflned on the pivot by s. pin or key 17. The plates`63 'and 64 are 'arranged between the head or flange. of the cam and the washer 're as clearly illustrated in rig. 14 er i nurA suitable handle 78 by means of which it is parthe drawings. and the pivot is provided withl muy rotated to @neet e mauve vertical disable Y movement ofthe bottom transverse plates 64 and 65. The eccentric l2 rolls inthe arcuate slot or opening '13 of the transverse plate 64 and is adapted to extend the flange 68 sufnciently belowl the lower' edgeof the plate 63 tc engage theflange 68 with the keepers 69 and after such engagement a cam is adapted to be operated to place the screen under tension and produce aA tight interlocking engagement between the flange 68 and the hook-shaped engaging yportion I1 of the keeper so that there will be no liability' of the bottom of the screen accidentaly becoming dis-.

engaged from the keepers. The keeper and the iso flange are arranged at a slight inclination due to .the inclination of the upper face of the sill 'I9 and this with the tension of the Ascreen will maintain the flange and the keeper securely interlocked. In practice the transverse plate 64 will fit against the window sill and a fiy and insect tight closure will be effected at the bottom of the screen without employing the flexible extension of the screen heretofore described.
