ATTACHING MEANS FOR ROLLED SCREENS Filed Feb. 20, 1930 Patented Apr. 28, 1931 :WILLIAM J. nuFrIcY, or DENVER, COLORADO 'AT'TACI-IING MEANS For. ROLLED scams Application filed February 20,1930. Serial No. 429,915.

This invention relates to improvements in roll screensfor windows and has reference more particularly to an improved device for attaching the end of the screen to the sash.

Where windows are provided with screens that are built into the window frame and secured to spring rollers it is customary to provide alatching cleviceby means of which the end of the screen can be attached to the end of the sash in sucha manner that when the window sash. is movedto open position, the screen will be interposed in the opening thus formed. These attaching; devices must be so constructed that they can be readily released when desired so that the window can be opened without interposing the screen.

It is the object of this inventionto-produce an improved device for making connection between the sash and the window'screen. and which. shall be of simple construction and have several marked advantages over analogous devices. .7

This invention, briefly described consists in a binding-stripwhich is adapted to heapattached. This screen is preferably a woven plied to the free end of the screen and'which is provided with-a lug that extends in the direction of thewidth of the screen and that has grooves on opposite sides. This lug extends for a considerable distance and is adapted to be engaged by means of: a clamping device secured to the window sashi- This clamping devicezconsists of a metal attach ment having an opening that is adapted to receive the plug and which is alsoprovided with two jaws that. can be moved towards or away from each other by a parallel motion and which are adapted to engage the grooves in the sides of the lug so as to hold the same attached to the windowsash. Y 'Having thus briefly described T the invention, the same will now be described in detail, and for this purpose reference will be had to the accompanying drawing in which the preferred embodiment of the invention has been illustrated, and in which:

Fig. 1 is a side elevation of a window showing my invention applied thereto, portions of the window frame being broken away to better disclose the construction;

Fig. 2 is a view taken on line 22, Fig.

1, and shows a portion of the upper surface of the binding strip and the lug;

Fig. 3 is a section taken on line 3-3, Fig. 1 F ig. 4 is, a section taken on line M, Fig. 3; .Fig. 5 is a side elevation of the upper. part of an automobiledoor showing my invention applied thereto and i ig. 6 is a section taken on line 6-6, Fig. 5. In the drawing reference numerals l and 2 designate respectively theupper and the lower sash of the window. The sash are slid- .abl'y mounted in the window frame whose sideshave been indicated by reference numerals 3 and 4. As. both of the sash are pro.- vided with the same attaching means, this description will be limited to the lower sash and vtheparts that are associated therewith I and it will be understoodthat the parts as sociated with theupper sash are of the same construction. The window frame is provided at the top and at the bottom with compartments 5 in which arellocatedrollers of the type employed in'connection with window shades and to which ,a'. flexible, screen 6 is wire screen of the usual construction and may be made of iron or copper as may be found most desirable The sides of the window frame are-provided with metal strips 7 that have .inwardly'e'xtending flanges 8 spaced a short distance apart in the-manner shown in Figs. 2 andl3. The screen. 6, is adapted to move between the flangesS which therefore serve as guides for-the edgesof the screen and since the window sash is provided with grooves 9 for the reception of these flanges, they form a satisfactory weather stripping which prevents the entry of dust and cold air. Secured to the free ends of the screens arebinding strips which are formed from sheet metal and which'have a cross section like that shown in Fig. 4. 'I he binding strips have anupper flatsurface 10 and are reversely bent and have parallel inwardly extending portions 11 whose inner 'edgesare downwardly and inwardly inclined as indicated by numeral 12; The ends of the screens are placed between the inclined sides l2 and are held in place by means .of wedges 13. Projectingupwardly from the upper surface 10 which the screen passes 1 is a lug 14.. This lug is of considerable tending flanges l6 and 17. The width-of this, member is equal to the thicliness of the 'win dow sash and is applied't o the latter in the manner shown in Fig. l, from which will beseen that the-lower endofthe window sash is cut away to'form agroove-lS for the reception 'of the movable parts oi the device,

' andwhich is also provided with alnotch 19 in whichthe operating handle is located; The flange or web '15 is provided with an el'on'ga ted slot 20 of such length and width'that the lug 14c can readily "pass' through it. 1 Secured -to the inner surface of web 15 aretwo jaws 21 and 22.} These jaws are provided at their endswith inclined slots 23 and are secured to part115 by' means otrivets 24 that pass throughthe inclinedslots. Slots 23 arereversely arranged in the two members in the manner shown in-F-ig. 3 and therefore when jaws 21 and2 2 are moved to the left, they will spread apart, while, it theycare moved to the right, they will move together with aparallel motion. For the purposeof moving thetwo jaw members, each of themhave beenprm vided with. a lateral 'extension25 that is reversely bent andarranged to' overlie leach otherin themanner shown in Figs; 8 and 4. 2

One of theseproj ections is'provided with two slots 26and the other hastwo rivets 27 that.

project throughthese' slots. "A handle 28 is secured to the upper member 25 and extends through an" opening in the flange- 17 in the manner shown in Fig; 4. The "handle terminates in aknob 29 that is accessiblefrom the outside and by means of which-the jaw meme bers 21-and 22 can befmoved longitudinally so as to cause'them to approach and recede from eachotheri for the purpose of engaging or releasing the lug 14-: The gaw members 21 and22 can be moved apart a suiiicient dis+ tance'to. admit the plug-i l andtheycan then be moved together so as-to extend intothe grooves on the opposite sides of thisplug.

WVhen the window sash are in closed position, the jaw members 2l and/22 must be spread apartso that the'lug 14: can passbetween. them and if it is not desiredto use the screen-the-window sash can be opened and closed independently of the screen. If it is desiredto interpose the screeninthe opening, the jaw members are'moved to operalong with it in the manner indicated in the drawing.

By employing a single lug of considerable length and engaging the same by two jaws that move parallel to each other, the screen can he very rigidly attached to the window sash. If the screen should bedestroyed for any reason,:itcan be readily-removed by removing the Wedge-s 13 and a new screen subst tuted. f

"In'Figs; 5 and'6"I"have shown my improved attached device secured to the glass of an automobile" door, in these figures numeral 30 designatesthe door and numeral 31 the roll screen, while numeral 32 indicates the movable glass. Secured'ito the upper edge oi the glass isan attaching-device that is similar in alli respectto'the "one 'that is secured to the window sash with this exception, that the fiangesi33 and 34that correspond' to'the flanges-16 andllt' have inwardly extending portions 35 I that; terminate Min downwardly extending'ifian'ges 36 that are spaced apart a sui'l'icient distanceto permit the glass tobe inserted between them and the attaching device is then secured. to the-glass by means "of bolts 87. When 'thel'screenis not in use and the window is open, the attaching deviceiformsanarin rest and also serves to close the opening intdthe door so as to prevent dirt*and1dust from-passing into the interior of thei'doonv' 3 r r I 7 From the 1 above adescription it' will be apparent that lhave'pro'ducedza simple and substantial attaching device forwuseiwi th roll screens and by means ofzwhich the' screen can be quickly attached to orndisconnected fromthe'wi ndow sashfl. pf" i Having 'describedthe 'inventionIwhat claiinedas'new is: i -f A clamping. device-for use'with roll screens comprising a'member adaptedto be secured to a window sash,said,member having an elongated opening adaptedzto receive a long narrow plug, a j aw; member located 0n'-'each side of the opening, each of the jaw members having a; plurality of inclined slots adapted to receive pins torisecurmg them n place,'the
