To all whom t may concern v Be it known that I, CARL GUs'rAv Mone- NER, a citizen of the United States, residing atHarvey, in the county of Cook and State ofIllinols, have invented certain new and useful Improvements in Screens for Car- Vindows; and I do deelare'the following to be a full, clear,

and exact description of the invention, such Yas will enable others skilled in the art to which it appertains' to make and use the same.

This inventionrelates to screens for car windows.

One object of the invention is to provide a screen of this character having an improved construction and -arrangement of frame, between the members of which the edges of the wire screen covering are firmly secured.

Another object is to provide an improved construction and arrangement of combined sash parting strips, screen guides and weather strips arranged between the inner and outer sash and adapted to slidably sup.- port and uide the screen.

A furt 1er object is to provide an improved means for` detachably holding the screen in engagement wit-h its guides whereby the screen may be readily removed when desired and having means for supporting the screen in raised or in partly raised p0- sition.

lVith these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings; Figure l is an inner side view o a portion of one side of acar, and a window showing my improved screen appliedthereto and in a lowered position; Fig. 2 is a vertical cross sectional view on the line 2 2 of Fig. l; Fig. 3 is a similar view showing the window sash lowered and the screen raised to an inoperative position; Fig. 4 is a horizontal sectional view through the window frame and screen on an enlarged scale with the central portion of the sash and screen frame broken out; Fig. 5 is an inner side view of the screen and its retaining mechanism with parts broken out; Fig. 6 is an enlarged/ininv the screen fastenin ner side y', w of the upperleft hand corner of the scree nd its retaining member showing the nanne'r in which the upper end of said retai to the screen frame; Fig. 7 is a top plan or 'upper edge view of the parts shown in Fig. 6; Fig. 8 1s a horizontal sectional view thereof on the line 8 8 of Fig. 6; Fig. 9 isa side edge View' of thef parts shown in Fig; 6; Fig. 10 is a cross sectional view of said parts taken on `the line 10-10 of Fig. 6; Fig. 11 is a horizontal sectional view taken on the line 11-11 of Fig. 6; Fig. 12 is an enlarged front side view of the screen frame; Fig. 13 is a top upper edge view thereof; Fig. 14 1s a horizontal sectional view on the line lll-14 of Fig. 12; Fig. 15 is a front side View of the lower left hand corner of the screen frame and the lower end of the screen retaining member; Fig. 16 is a similar View with the lower portion of the frame in section to illustrate this end of the screen fastening mechanism and means for holding the lower end of the screen retaining member in place; Fig. 17 is a vertical cross sectionv on the line 17..-17 of Fig. 16; Fig. 1.8 is a detail side view partly in section of the locking plunger for the lower left hand corner of the screen; Fig. 19' is an enlarged cross sectional view, on the line 19-19 of upper edge of the screen` is secured in the left hand upper corner of the frame; Fig. 20 is an enlarged front side view of the lower right hand corne-r of the screen showmechanism for this si e of the screen, and i lustrating the means whereby the screen fastening devices of the Fig. '-8 showing thev `manner in which the Weather strip for the ingmember is detachablysecured the upper right hand corner of plan for opposite sides of the screen areretracted to permit the screen to be raised; Fig. 21 is a similar view with the lower portion of the frame in section to more clearly illustrate the screen fastening and releasing devices shown in' Fig. 20; Fig. 22 is a cross sectional view on the line 22-22 of Fig. 20; Fig. `23 is a detail plan view of the leftA hand releasing devices and means for vconnectingthe same to the left hand fastening mechanism of the screen; Fig. 24 is an outer side or face A view of the right hand parting strip and screen guide; Fig. 25 is a similar view with A 27 is a view similar to Fig. 26 with the outer' member of the strip removed and parts of the inner member broken away and in section; Fig. 28 is ahorizontal sectional view on the line 28-28 of Fig. 26 Fig.v 29 is a similar view on the line 29-29 vof Fig. 26; Fig. 30 is a similar view on the line 30-30 of Fig. 26; Fig. 31 is a similar 'view on the line 31-31 of Fig. 26; Fig. 32 is a similar4 view on the line 32ri2^of Fig. 26; Fig. 33 is a horizontal sectional view on the` line 33-33 of Fig. 24; Fig. 34 is a similar view on the line 34-34of Fig. 24'; Fig. 35 is anI 4enlarged vertical sectional view o a portion of the right hand parting strip and screen guide taken on the line 35-35iof Fig. 24;

My improved screen 1 comprises a frame, the side, top and bottom bars of which are formed of inner and outer channel shaped

members

2 and 3. The inner edges of the

members

2 and 3 of the bars are bent at right angles to form overlapping

flanges

4 and 4, the flanges 4 on the outer members to form beads 6 between vwhich vand the flanges 4 is firmly gripped the edges of the screen cover or fabric 7. The edges of the screen fabric 7, after passing between the flanges 4 and 4a extend along the inner side ofthe outer member 3 of^the frame bars as shown.

The outer edges of the members 2 of the frame bars are bent inwardly to form a slightly curved flange 8 and the adjacent edges of the outer members of the top, bottom and right hand side bars of the frame are carried over the edge of said flangeand bent to form tubes or cylindrical extensions 5, the purposes of which will be hereinafter described. The edge of the outer member 3 of the left hand side bar of the frame adjacent to the flange 8 of the inside member of said bar is bent to form a curved flange 9, which fits closely against the flange 8 as Vclearly showniin Fig. 11 of the drawings, said curved flange 9 forming a seat to receive a screen retaining member 1'0 hereinafter described. l

The screen retaining member 10 is in the form of a tubular cylindrical rod or bar the upperend of-which terminates a short dis tance below the upper edge of the screen and has secured therein an upwardly extending pin 0r stud 11 which is loosely engaged with an eye 12 in the-outer end of a plunger 13 which is slidably mounted in a guide tube 14 securedin the adjacent end of the tube or. cylinder 5 of the upper bar of the screen frame by a lpin 15 arranged diagonally through the same, asy shown in dotted lines in Fig. 19 of the drawings. The'plunger 13 is normally projected or forced outwardly to bring the eye 12 in the outer end thereof in line with the pin 11 of the retaining rod by a coiled spring 16 which is arrangedy in the tube 14 between the inner end of the plunger and a block 17 secured in the inner vvend of .thetube as clearly shown in Fig. 8

of the drawing.' The outward movement of the plunger by the spring 16 is limited by a stop screw 18 arranged in the lplunger and having its outer'end engaged with a slot 19 in the tube 14 as shown. In the adjacent portion of the tube or cylinder 5 of the upper bar of the screen frame is also formed aslot 20, which registers with the slot 19 in the tube 14 and through said registering slots and into engagement with a recess or socket 21 in the plunger, is adapted t'o be inserted a wire nail or any other instrument whereby the plunger may be retracted when 1the pin 11 of the screen retaining rod 10 is disengaged therefrom, thus preventing the projecting end of the plunger 13 from interfering with the removal of the screen from its guide ways, as will be hereinafter more g fully described. having their 'edges bent or folded inwardly 5 The lower end of the screen retaining rod @or bar 1-0 has formed therein a transverse ,passage or aperture 22 with which is en- :gaged the reduced outer end 23 'of a left i hand screen fastening or locking plunger 24 which is slidably mounted in the tube or cylinder 5 of the lower bar of the screen frame as clearly shown in Fig. 16 of the drawings. The plunger 24 is normally projected or forced outwardly to an operative position to engage the reduced end 23 thereof with the passage 22 of the retaining mem- :ber' 10 by a coiled spring 25 which is arranged in the tube 5 between the inner end of the plunger and a plug 26vfastened in said tube and spaced a suitable distance 'from the plunger as clearly shown in Fig. A16. The plunger '24 is provided with a retracting mechanism comprising a retracting rod 27 having its outer end inserted through a bore in the plunger 24 and extension 23, in

www l and has its inner en'dy liattenedandlbentto form a zrectangular .hook 28 which is enf.

- gaged with the slotted inner end of a short bar 29 forming part ofa retracting lever or thumb piece 30 which is arranged in a hand hole or opening 31 formed in the lower bar of the screen frame as clearly shown in Figs.A 20 ,and 21 of the drawings.

Uoacting with the left hand plunger 24 is a right hand screen locking or fastening plunger 32 which isslidably engaged with the right hand end of the tube 5 of the lower v frame bar. The plunger-32 is forced outwardly to normally project the-end thereof beyond the right hand edge of the screen frame by a coiled spring 33 arranged in the tube 5 between the inner end vof the plunger and a plug'34 secured in thetube a suitable distance from the inner end of the plunger as shown. The plunger 32 is retracted to release the screen by a plunger retracting rod 35, the outer end of which extends througha bore in the plunger and has its end riveted or otherwise rmly secured to the outer end of the plunger-as shown at 36 in Fig. 21 of the drawings. The inner portion of the retracting rod 35 has asliding engagement with a passage in the plug 34 and the inner end of said .rod is firmly secured to a retracting lever or thumb piece 37 which is also arranged inthe opening 31 -in the lower bar of the screen frame a suitable distance from vthe thumb piece 30 of the retracting mechanism for the left hand plunger 24. By thus arranging the levers or thumb pieces 37 it will be seen that in order to retract Athe

screen fastening plungers

24 and 32 it is simply necessaryrto grip the thumb pieces or levers and to draw the same inwardly or toward each other, which operation will, through the retracting rods connecting said levers with the plungers, retract or draw the latter inwardly against the pressure of their projecting springs. The inward movement of the levers or

thumb pieces

30 and 37 is preferably limited by a stop block 38 arranged in the vtube 5 as shown. When Vthe retracting mechanism just described is operated the reduced end 23 of the plunger 24 will be retracted to bringl the extremity f said reduced en d flush'with the outer side of the retaining rod 10 which is sufficient to release this side of the screen tol permit-the latter to be ra1sed.- If, however, it is -desired to release the lower endof the retaining rod 10 to permit the screen tol the! passag iefectrhfisfaddi. 01 ser@ Mythe; let

the end 23 thereoffrom the passage 22 in the retaining rod aswill"be readily understood. When the ,plunger is retractedV toits greatest extent for releasing'therod'10,.thekr loose c0nnection. between .the rectangular hook 28 on `the inner end ofthe retracting rod 27 and the slotin the end ofthe bar 29 will permit the hooked. inner end of there?U tract-ing rod 27 to slide back inthe y slot of the bar 29, so that the connectionbetweenthe rod and the bar will not interfereA with the retractingniovement of the plunger,24. In the tube or cylinder 5 of the upper'lbar,

of the'screen frame .is arranged a weather strip 41 which projects outwardly fromthe outer sideof the tube in a: position toengage the adjacent side of the outer sash of the window, thus closing the space and pre- 4 venti-ng entrance of dust vor insects between the inner side of the outer sash and the upper end of the screen. The weather strip 41 may be-constructed of any suitable material. and is preferably folded upon itself lengthwise and has its edges insertedy between the edge of the tube 5 and the adjav cent portion of the outer member 3 ofthe upper frame bar. vThe ends of the weather .strip 41 when thus engaged with the ltube 5 are secured therein by a longitudinallydisposed metal bai-,42 which is curved longitudinally and inserted in they tube 5, said bar having its edges bent or'folded inwardly and having secured. between the foldedy upper edge thereof the inner edges of the weather strip 41 as clearly shown in Fig. -10

ofthe drawing. The strip 41 at the `end of the tube 5 in which the plunger supportirngl tube 14 is arranged has its inner ends rsecured by .rivetingfthe same to the side ofthe tube 14, which is cut away along the outer side of the tube 5` as clearly shown at 14'.. in Fig. 19 ofthe drawings.. f

screen retainingrodflqon ,the leftlhand,

1s slidab'ly supported be-` lowered to any desired elevation. The right the purpose of which will be hereinafter describ d.

The inner member 45 of the strip extends from the bottom or sill of the window upwardly to a point above the upper edges of the sashes and screen frame when raised to their greatest extent. Secured to the inner member 45 ofv the strip is an outer channel shapedl screen guiding member 47 having on its edges, right angular laterally projecting clamping ianges 48 between which and the flanges 46 on the side edges ofk the inner member 45 is clamped a weather strip 49. The wea-ther strip 49 is preferably formed from a single piece of material of suitable length and width, said strip having its edges folded or doubled upon itself to form loops 50. The edges of the folded material overlap and when the strip is thus arranged, it is engaged with and riveted to the inner side of the outer guide member 47 of the strip with its folded edges clamped between the ianges 46 and 48 of the inner and outer members of the parting strip and projecting beyond the opposite sides of the strip in position to engage' the inner surfaces ofthe adjacent sides of the sashes as clearly shown in Figs. 4 and 30 of the drawings. It will be noted that the weather strips 49 extend upwardly only to the height of the lower sash and it will also be noted that the guide strip 47 is formed in upper and lower sections, the lower section terminating at the height of the screen and that the upper` section of said guide strip begins at the upper end of the lower section and extends'substantially to .the upper end of the inner member. The inner and outer members of the parting strip are secured to the inner side of the window frame between the sashes a and b by screws or similar fastening devices 50.

Arranged at suitable points in the inner member 45 of the' parting strip are screen engaging and holding springs 51, the lower portions of Vwhich are bent to form screen engaging surfaces 52 which project outwardly through slots 53 in the inner portions of theY outer guiding members 47 of the stop strips, said screen engaging surfaces being slightly curved or convex to tit the curvature of the cylindrical outer surface of thetube 5 of the side bar of the screen when said tube is engaged with the grooves or channels of the guide member 47 as is clearlyindicated in Figs. 31 and 32 of the drawings. It willbe noted that the springs 1 are arranged to 'project at an angle of forty-five degrees and4 that the prop jecting portions of said springs engage the tube 5 of the screen frame to one side of the tube as shown. The springs 51 when thus arranged will eectually hold the screen from rattlinrg and will temporarily support the same a `any desired elevation.l

In the lower ends of the inner and

outer members

45 and 47 of the parting strip are formed alined holes 54 with which are engaged the 'rojecting ends of the right hand screen fast ning plunger 32 whereby this side of the screen may be fastened in its lowered position. Arranged in the upper portion of ,the inner member45 of the parting strip 43 near the upper end thereof is a screen supporting .spring 55, said spring curving outwardly and having said upper end bent inwardly at substantially right angles to form a seat 56 and then bent upwardly atright angles to form a spring retracting lug 57. The outwardly extended right angularly bent upper end of the spring 55 projects through a slot 58 formed in the inner portion of the outer guide member 47 and is inposition to receive the projecting end of thel plunger 32 when the screen is raised to a sutlicient extent to bring said end of the plunger above the seat 56. In thus raising the screen the projecting end of the plunger -coming into engagement with the outwardly extending upper portion of the spring forces the upper end of the latter back through a slot 59 formed in the rear side of the member 45 of the strip and into a recess 60 formed in the adjacent portion of the window frame.

plunger has .passed the outwardly projecting upper portion of the spring, the'same will spring outwardly to bring the seat 56 bene-ath the end of the plunger, said seat thus supporting the screen in its raised position.

In order to release or retract the spring lto permit the end of the plunger to pass the same when the screen is to be lowered, I provide a suitable spring retracting mechanism comprising a releasingirod 61 which is arranged in one corner of the inner member 45 of the parting strip and is supported and adapted to turn in upper and lower bearing/

plates

62 and 63 which are riveted to the inner side of the member 45 as shown. On the upper end of the rod 61 is formed a right angularly bent slightly curved `spring retracting finger 64 which projects and works through a slot 65 in the upper bearing plate 62 and is adapted to be engaged with the ret-racting lug 57 on the upper end of the spring 55 whereby when the rod 61 is turned in the proper. direction, said armf64 will byits engagement with the lug 57 retract the right angular projecting upper end or seat 56 of the spring, thus permitting the end of the plunger 32 to move downwardly past the spring. The rod 61 is of such length that its lower end will'be After the end of thev of the guide member 47 putward movement of the spring as cle-arly tube 5 on the side of the holding the screen against rattling.

-thus arranged the upper in a position to be conveniently reached for retracting the spring and` on the lower end of -said rod isformed aright angularly projecting crank arm 66 which projects through and is adapted-tube turned in a slot 67 inthe lower bearing plate 63 of the In orderto' prevent the upper portionof the screen from rattling when vin a full raised position and supported by thespr'ing 55,"1 provide av screen holding spring 68 ywhich 1s secured at its lower end in a suitable position in the upper portion ofthe inner member 45 of the :stop strip 43. The upper end of the spring68 curves outwardly andprojects through av slot 69 in the adjacent portion of the upper section of the 1nner guide member 47, jecting upper end of the spring being bent inwardly" and upwardly at right angles to form a stop 70 which engages the inner side and thus limits the shown'in Fig. 36 of thevdrawlngs. When v end of the spring 68 is in position to frictionally engage the screen frame thus The left' hand parting strip and screen guidevis constructed similarly to the right hand parting strip and comprises an inner channel shaped member'71 having on its sides inwardly extending-flanges 72. On the innerv member7l is arrangedv an outer guide member 73 `having' a central groove or channel corresponding t'o, but of less depth than the channel ofthe corresponding member 47 of the parting strip 43. The edges ofthe member 73- are in the form of clamping flanges 74 between which and the lianges 72 are clamped the looped edge of posite partiilg gfgfhevmgmbersj 71 ana vagoflf the-.Parting pasean;
