12 Qlaims. (Cl. 16ii-91) This invention relates to a new and substantially universally adaptable combination screen and storm window for application to steel sash such as are used in basement windows.

It has been most diflicult in the past for dealers to satisfy customers demands for screens and storm windows to fit basement steel sash already installed, because most manufacturers, if they make any screens at all, supply them only to fit the steel sash of their own manufacture, and hence, unless a dealer knows the specific make of steel sash to be fitted and orders screens and storm windows to fit that particular make, the need usually cannot be supplied. It is, therefore, the principal object of my invention to provide a universally adaptable screen which, with little or no alteration at all, can be applied to any one of the ten or more makes of basement'steel sash, partly by virtue of the provision of new and improved fastening clips supplied with the screens, one at each end to attach to the corresponding ends of the sash frame, and partly by virtue of the provision at the lower inner corners of the screen frame of knock-outs, the removal of which provide clearance openings for the exposed trunnions that are provided on the ends of certain makes of sash. In connection with each screen I also provide a pair of quickly attachable sheet metal box enclosures designed to fit in the knock-out holes and adapted to be clinched in place at opposite ends by the bending over of lugs provided on opposite ends of these sheet metal parts, so that no openings are left for insects and bugs to enter.

In accordance with the invention, each screen is made to provide a recess in the outer face to accommodate a glass storm panel and spring clips are supplied in connection with the fastening clips under the heads of the fastening screws therefor which can be quickly turned from a retracted out-of-the-way position to an operative position holding the storm panel in place under spring pressure.

The invention is illustrated in the accompanying drawing, in which- Fig. 1 is a perspective view of a basement window showing applied to the steel frame thereof a screen fitted with fastening clips in accordance with my invention;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a view similar to a portion of Fig. 2 showing the method of assembling the fastening clips onto the ends of the screen frame;

Fig. 4 is a view similar to Fig. 2 showing a glass storm panel in place in the screen frame and showing one of the two spring clips provided in connection with the screws on the two fastening clips for retaining the glass storm panel;

Fig. 5 is a view on the line 55 of Fig. l with the sheet metal box enclosure removed so as to disclose the hole formed where one of the two knock-outs that are provided in the opposite ends of the screen frame has been knocked out, and

Figs. 6 and 7 are two views of one of the sheet metal boxes intended for application in the knock-out holes.

The same reference numerals are applied to corresponding parts throughout these views.

Referring to the drawing, the reference numeral 8 designates generally a rectangular window screen provided in accordance with my invention for substantially universal application to basement steel sash, like that indicated generally by the reference numeral 9, the screen having a formed sheet metal frame 10 the top, bottom and end rails of which have right angle flanges 11 in coplanar relationship on the back for abutment with the outer face 12 of the front flange 13 of the T-iron top, bottom and end members of the frame 14 of the steel sash. The hinged steel sash proper is indicated at 15 in Figs. 1 and 4, .the one disclosed being of the type having trunnions 16 at the bottom at the opposite ends which fulcrum at 17 on the front face 12 on the frame 14 in the hinging of the sash, and, inasmuch as these projecting trunnions require operating clearance in the frame 10 of the screen 8, knock-out portions are provided at the lower ends of the side rails of the screen frame it which can easily be knocked out, in the same well-known manner that an electrician removes knock-out slugs from an outlet box, to provide the generally rectangular openings like that shown at 18 in Fig. 5, in which the trunnions 17 find ample operating clearance, as indicated by the full and dotted line showings of the one trunnion 16 in that figure When these openings 18 have to be provided, they can be easily closedby the application of small sheet metal box enclosures 19 as shown in Fig. 1. The boxes 19 are of rectangular form, as seen in Figs. 6 and 7, and each box has top and bottom end walls 20 which have the inner edges 21 in coplanar relationship with the inner edge. 22 of the front wall 23 for tight abutment against the vertical end face of the side frame 10 at the top and bottom and along the left hand side of opening 18 in Fig. 5 alongside flange 11. The back wall 24 of each box is cut away, as at 25, to provide clearance for the flange 11 so that the back wall 24 may have tight abutment with the front face 12 against which the flange 11 has abutment. There are small rectangular lugs 26 projecting from the edge 21 on the top and bottom walls 20 of the box, which, when the box is properly placed coveringthe opening 18, project neatly through the opening at the top and bottom thereof, and these lugs are adapted to be bent into diverging relationship on the inner side of the screen frame 10, as indicated in dotted lines in Fig. 6, to clinch the box enclosure in place, thereby leaving no openings through which insects and bugs would otherwise be apt to enter. It will be seen, therefore, that whether the trunnions on the sash 15 are exposed on the outer side of the window frame 14 or not makes no difference in the universal adaptability of the screen for the present invention, because the frame of each screen will be equipped with the knock-out portions, which if they do not have to be knocked out because of the provision of concealed trunnions on a given sash, will keep the screen frame fully closed against insects and bugs, but which may be readily knocked out wherever the trunnions on the sash are exposed and have to be provided for as above described. The openings thus made can be quickly and easily closed by the application of the two sheet metal box enclosures 19 provided with each screen for that purpose.

A pair of spring metal fastening clips 27 is provided for each screen 8, one at each end of the frame 10 approximately at the middle thereof, as shown in Fig. 1, a short vertical slot 28 being provided in the mid portion of each end of the frame 10 through which first the J- shaped inner end portion 29 (as in Fig. 3) and then the L-shaped main body portion 30 may he slipped (as shown in Figs. 1, 2 and 4), to dispose the clip 27 with the one leg 31 of the L lying parallel to the inner side of head 35 abutting the outer or front face36 of the frame,

asshown in Fig. 2. The screw 33, as clearly appearsin .Fig. 2, hias the shankportion thereof of a length jlequal.

to the distance from the outer or' front face, '3 6 of,1the frameto the outer face of thefjflan'ge 11, so that-the screw head canbe in contact with the' outer or front face '36 of the frame atthe same time that theend oflthe shank is in contact with the outer'face of the flange ll, as'appears in Fig. 2. Hence, when the fscrew .3 3 is tightened, the head '35 of. the screw and the legof the J-shaped end portion 29 of the clip 27 are drawn together, enough leeway being provided in theslot 28 in a fore and aft direction to allow a given amount of fore and aft movement of the end portion 32 of the clip 27 therein V V v 20 bination including a storm glass panel fitting 1n the-recess so that the head 35 .of the screw 33 can be jammed secure- "ly against the front face 36 and the end of the shank of the screw. 33 can be jammed securely 'agains't theouter face of the flange 11, and, at the same time the 'Jshaped end portion 29 of the clip 27 can be drawn up firmlylagainst the inner sidexof the flange 14. on the window frame, thereby fastening thescreen 8 quite firmly and without danger of anyspace being left between the flange 11 and the outer face of the sash'frame 10, through T; which flies and other insects and bugs would be apt to "pass.

The J-shaped end portions 29 of the two clips 27 are thin enough in relation to the tightness of fit of the sash 15 sorthat' there. is no problem presentedjin the fastening of the sash ,to the frame at the top in the usual way in closed position. Here again, it should' be manifest that so long as the length dimension o f the screen in relation to the length dimension of the'steel sash to be fitted is correct the screen may be applied even if it is not an'exact fit so far as height dimension 7 of the sash is concerned, although it is believed that most sash manufacturers adhere to standard sizes and no appreciable run-out need be anticipated. 7

Where only the screen '8 is applied, it may removed for storage with other'sc reens when the others on the house are removecl'in the fall. 'Otherwise, glass storm panelsflike that indicated at 37 in Fig. 4, may be inserted in the recessed front portions 38 of the screen frames and secured in place in any-suit'able or preferred manner.

I prefer to provide for the-fasteningiof each such glass storm panel a spring steel-retaining clip 39 under the head 35 of each of the'screw's'33. The clip 39*comprises an elongated spring steel body portion 40,1near' one end of which a hole'41 is provided to receive the shank of the screw 33 with a fairly close working fit, pron the other end of which is an 'inwardly' bentlJ s-haped portion 4 2, which, when the screw 33'is tightened and theiclip is in place abutting the marginal frame 33 of -the panel 37, is pressed tightly but resiliently against the frame to 'hold the panel 37 securely in place. An inwardlybent -end portion 44 on the other end of thejc'lip 39 has abutment at its extremity-with the shank of the screw at some .distancefrom the, head 35'1to' provide a good bracing *effect for the clip With this construction the clip'may be easily turned'toan out-of-the-way position especially when the screw 33is loosened a trifle; Hence, applicationiand removal of 'aglass storm panel 37 takes very littletime and effort: t: i'

In passing, it will be noticed that theredge portions of the screen material 45 are clamped by a rod 46 pressed ,into a channel that is formed in screen frame 10 on the inner sidethereof around the storm window recess 38.
