i The object of my invention is to providea window screen construction of simple, dura# le, and comparatively inexpensive construction. g Y fil AnotherA and most important object of my invention is to provide a screen construction wherein the screen frame and the mounting means therefor are made of metal, wood, or other suitable material, the screen frames being easily and conveniently removable from the insideof the building to which the screen is applied and equallyas well adapted vto be replaced. l y I A 'Still a further object is to provide a screen construction consisting of'mounting bars to `bepermanently attached tov a window frame and a pair of' screen units adapted to be mounted thereon, whichniay be easily removed through the lower half of the window opening after the inner sash has been raised. Still another object is to provide-a screen construction so constructed as to compensate for expansion and contraction so that a good lit and one'which is ily-tightresults Vat all 95 times. y A Still a further object is toprovide in connection with one of the screen units a movable cover plate which may be raised for the purpose of sweeping dust and the like from the window sill where it has accumulated.

More particularly, it is my object to provide in connectionY with the supporting bars, a friction means for holding one of the screen units after it has been inserted and raised tov position and latching means for holding the other screen unit in position after it has been placed against the supporting bars. I

Still a further object is to provide my construction easily adapted'to be covered by fully set forth, pointedl out in my claims, and

On the accompanying draw ings, I have used the reference numeral 10 to indicate the sill of an ordinary Y double sashV window frame. The window frame also includes side casings 12, a headcasing 14, side blindstops 16,'which` are ordinarily embe @idea in Side jainbs`18 and a head blind stop 2O ordinarily .embedded ina head jamb 22.

The foregoing description is of the ordinary type of window to which I apply my window screen construction and forms no part of vmy invention.

My window frame construction consists of a pair of spacer and supporting bars A and andl consisting of two parts; an

Aa removable frame covered vwith screen wire upper unit B and a lower unit C. Each supporting bar A consists of a flange 24 adapted to'be fastened by'means of screws 26 tothe s of the window frame.

ide jambs 1 8 Portions 28 are formed on the bars A which extend toward each other, as clearly illustrated in Figure 5 of the drawings. The portions 28 terminate in inwardly opening channels 30. The channels 30 it will be noted, are closer together than the facing surfaces of the side blind stops 16 for a purpose which will hereinafter be more fully set forth. The portions 28 in this connection, serve the purpose of spacing the channels 30 from the side jambs 18;

The supporting bars A are made of the proper length to fit between the h'ea'd jamb 22 and the sill 10 of the window frame. The lower ends of the bars A ofcourse, are cut at angle to t'thefsill, as shown in Figure "2.

Means are provided on the supporting bars A to hold the screen units Brand C in position and these means' consist of friction plates 32 and latches 34. rlhe friction plates 32 have -`flanges A36 which `are held in position against the flanges 24 of the supporting bars A by means of some of the screws v26, as clearly shown in Figure 5. Y

The Ilower ends of the friction plates 32 are befnt slightly away from the supporting `bars A, as indicated at 38. rlhe latches 34 are pivoted to the supporting bars A by means of rivets or the like 40.

The screen units B and C each consists of a frame covered with screen wire. `The frame of the u'n-it B comprises side members 42 and top and bottom members 44 and 46. TheV frame of the `unit C comprises side members 48 and top Iand bottom members 50- and 52. of the members 42, 44, 46, 48, 50 and 52 is formed in the same die and consists of a liange portion 54, an inwardly opening channel portion 56, and an outwardly opening channel portion 58.

Referring to Figure 6 Vof the drawings, the

ends of the : members 44, 46, 50 and 52 areV connected with the members 42 and 48, as illustrated. Referring for instance, to the upfperleft hand corner of the unit B shown in Figure l, the member 42 is cut away as indicated at 60 to receive the outwardly openchannel portion 56 of the member. 44. The channel portion 56 is formed with a lip' 62 adapted lto rest against the bottom ofthechannel portion y56 ofthe member 42. When these two parts vare assembled together by moving the member 44 as indicated by the arrows, they appear as shown in Figure 7 and are rigidlylreld assembled relative to each other by spot welding at the'ipoin-ts referred to by the reference numeral 64; A .After the frames Yof the nfnits B and C have been fassemblled, the screen :covering v6G foreach of the frames is put 'on .in the fol* lowing described manner. rlhe 'covering 66 is oust slightly larger the outside dimensions of? tbe-screen and lis .flaid against the inside surface thereof. .In reach lframe the screen 66 assumes the position shown in full lines as 1t enters the channel. .For each screenframe of each unit, four of the Iille'r members 68 are provided. The

filler members 68 are formed of sheet metal sothat after being forced into the inwardly opening channels 56 theymay be pierced by case hardened screws 70 which' form therein, threads in the members 68 as they enter p them.-

` Openings 72 are provi-ded in the. bottoms of the channels 56 for receiving the screws 70. Besides causing a tight engagement between the lscreen frame and the lscreen 66, the iiller members 68 serve to stretch the wire 66 Atightly over the screen frame.'v

The side members 48 of the screenunit 'C extend yconsiderably.lower than the bottom member 52 thereof. Thus, a space is left between the screen wire 66fand the lower end of theiframe of the unit C. This sparce is provided for the purpose of sweeping dust Vand dirt from the window sill out-:of-

A cover platev 74 is provided to span the distance between the bottom member 52and the wind-ow sill 10@ The plate 74 is provided with =a pair `of slot-ted openings 76 through which rivets 7 8 entend. The rivets 7 8 are securedt-othe flanges 54 zor the side members 48. By means of the slotted openh ings 76 the Ycover plate 74 may be raised fand -th en swung-slightly lto the'lright. as viewed in Figure '4, so that 'the portions v8O of the slots 76 coact with 'the rivets 7 8, whereby the cover plate may be held in raised position. A strip of metal issecured to the upper end of the frame Iof the screen vunit C for forming a tl'ange 82 to 'Contact with `the upper screen uni-t installation uml practical operation of my screen structure in the installation of my ldevice the ianges 24 of the supporting bars A are positioned against the side ja/mfbs 18 of the win-dow frame, asV shown in Figfure 5. The inner 'itc reo

edges fof the `flan-ges l24 are 'caused to Contact with the side Iblind stops i6, wherebythey serve to :position the-supporting bars A for aligning the 'channels 30 thereof with the ont-er surfaces of the s-ide (cas-ings 12. The screws 26 are then utilized for the purpose of permanently securing the vsilpporting bars A to the window frame.

The upper screen unit B Vmay now be placed ret aov

in the position of the lower screen unit with the flanges of the outwardly opening chanfnels thereof which are at the eXtreme side edges of the screen unit B positioned in the inwardly'opening. channels 30 of the supporting bars A. The screen unit B may now be pushed upwardly. The side members 42 thereof in being so pushed, will enter under the lip portions 38 of the friction plates 32 and when the screen unit B is in its uppers most position, as shown in Figure 2,' the plates 32 will serve to hold it in such position.

A filler 84 formed of wood or sheet metal may-be nailed to thehead jamb 22 for the purpose of filling the space between the upper screen unit B and the head blind stop 20. The lower screen unit C may now be placed with the lower end thereof on the sill l0 as shown in the dotted line position in Figure 2. The upper end thereof is then caused to swing inwardly as indicated by the arrow 86 (the latch members 34 being in raised position as shown at the left hand side of Fig-k i ure 4). The flange 82 will then contact with the upper screen unit B for closing the joint between the two units. Y

The latchesV 34 may now be swung downwardly, as indicated a-t the right hand side of Figure 4 and inv dotted lines at the left hand side thereof. Y .The inwardly opening channel SO of the supporting` bar A andthe outwardly opening channel 58 ofa side bar of one of the screenfframes coact with each other, as shown in Figure .5. By Vsuch coaction, ample space is left to allow for contraction and expansion of the screen frames or the window frame. Y

The inwardly opening channels of the supporting bars A are spaced closer together than the distance between the side blind stops 16 and the dimensions of the screen units B and C from side to side thereof are such that they can it into the channels 30.

The over-all width therefore, of the screen units B and C is less than the distance between the blind stops 16, whereby the screen units may be removed from the supporting bars A from the inside of the building. This is one of the main advantages of my construction. Y

In the event that the device is tobe used for a storm sash in the winter time, frames may be provided similar to the frames for the screen 66, but omitting the screen, the filler channels 68, and the screws 70.

The flanges 54 of the frame members may be faced with putty, as indicated at 88 in Figure 9. A pane of glass 90` is then placed against the putty and heldin position by metal clips 92. The clips 92 are fastened to ythe inwardly opening channels 56 of the frame members by means of screws or bolts 94.

My constructionworks very satisfactorily ltwo parts allows .for the units beingv reagainst said bar.

as astorm sash, since the entrance ofk air is eliminated by the double joint construction `consisting of the outwardly opening channels ofthe unit frames and the inwardly opening channels of the supporting bars A coacting with each-other, as shown in Figure-5. rllhe filler 84 preventsthe entrance of air at the toplof the storm sash, the flange 82 prevents the entrance of air at the center of the' storm sash, and the cover plate 74 prevents the entrance oflyairy below the storm` sash.

The cover plate'74 may bei broughtlto raised position for the-purpose lof'allowing ventilation through the'stormfsash. l'

From the foregoing construction vas'described in my specicationit will be obvious that I have provided -a' window yscreen or`V i moved through the openingleft'by thejinner sash ofthe window being raised. f v Some changes may be' made in the construction and arrangementef'the partsuof my v .device withoutdepartingfromy theA realsspirit and purpose of myv invention,'and' itis my intention to coverbymy claims, any modified` forms of struc-ture or'use of mechanical equivalents, which may be reasonably ineluded within their scope.'
