METAL BUILDING SCREEN Filed March `l5, 1932 gmentoz v Patented Sept. 6, 1932 i UNITED STATES CHARLESE. BRITTEN,. OF APOLLO, PENNSYLVANIA METAL BUILDING SCREEN 'Ihis invention relates to` vmetal building screens, and more particularly to screen door structures.

` AThe f advantages of metal screen structures for the doors and windows of buildings are obvious,A such metal vstructures being unaffected by4 moisture which causes the wooden frame structures of door and window screens to swell and warp. Moreover, a metal structure forV window or door screens, when made* of the proper materialand protected by paint or other surface coating composition will be far more durable than the wooden structures heretofore employed. However, metallic structures for the purpose stated ordinarily are open to the disadvantage thatv they cannot betrimmed for accurate fitting to door or window openings as can'wooden constructions.

An important object of the present invention is to provide a metallic door or window screen'which is adjustable whereby it` may be accurately fitted into the desired opening. vA Vfurther object is to provide novel means for adjusting the over-all size of'a metallic door or window screen wherein the adjustmentmay be easily and accurately accomplished. Y

A further object is to provide a device of l the character referred to wherein the adjusting action andv for protecting the screen fabric f against distortion while adjustments are being made. e

Other objects and advantages of the invention will become apparent during the course of the following description.

In the drawing I have shown one embodiment of the invention. In this showing: Y Figure l is a side elevation of a screen door, Figure 2 is asection on lineV 2 2 of Figure 1, parts being broken away,

' Figure 4 is a similar view yon line 4 4 of Figure l,

Figure 5 is a fragmentary perspective view of the upper end of the screen supporting C.,

lframe and associated elements, and,

Figure 6 is a similar view of the upper end ofthe door,l parts being shown separated.

- Referring to the drawing, the numeral'lO designates a holding and supporting frame ,m for the wire fabricll of the door or screen. T50 The frame 10 is preferably formed-of a solid rod of circular cross section, although it will be apparent that any suitable material may be employed. The frameisbent preferably l into rectangular shape to form vertical side rails 12 and upper and lower horizontal rails 13.V The wire 4fabric is cut to a size corresponding to the opening within the frame 10, and is then'placed within the opening and s brafzed, welded or otherwise secured to the rails of the frame.

The rails of the wire supporting frame are adapted to be concealed wholly within a metalframe structure. Referring to Figure l, it f will be noted that the metallic frame comprises generally a pair of vertical parallel side frame members 14 and upper and lower i horizontal frames l5 and 16. Each of these frames is identical in cross sectional shape, y... and such shape is indicated in Figure 2. It '80 will be apparent that each of the metallic frames is of a hollowv channel shape with its ends turned inwardly to form angular lips 1,7 defining a relatively small opening-therebetween. This opening is spaced for the reception of thefwire cloth 11, but is materially smaller than the rails -of the supporting frame 10. v f v 'Angle pieces 18 are arranged in opposite pairs at each corner of the main or outer frame. Each of these corner pieces is substantially L-shaped, as shown in Figure 6,

Vand includes inturned lips or flanges 19 at its outer edges adapted to overlie the outer edge portions of the hollow frame. As indicated, the flanges 19 are vof such width that their edges abut as shown at the right-hand side o f Figure 6. rlhe inner edges of the angle pieces turn inwardly at an angle as at 20 to lie against the angular lips 17. Accordingly mi ring to Figures 1 and 4, the numeral 24 designates a pair of channel members arranged with their open sides adjacent the wire cloth and forming intermediate frame members. These frame members extend into the side frame members 14, and for this purpose, the sides of the frame members 14 are parallel throughouttheir width at the point where the frame members 24 enter thereinto instead of being provided'with the angular lips 17. A plate 25 has one end Welded or otherwise secured against each outer face of each of the framemembers 14 and projects inwardly therebeyond. Each of the plates 25 is provided'with a slot 26, and a screw 27 extends through this slot and has threaded connection with an opening formed by stamping a boss 28 inwardly from .the adjacent frame member 24. The screw and slot arrangement just described is similar in construction and purpose to the similar means previously described in connection with the corner pieces 18.

Each supporting

frame rail

12 and 18 is provided adjacent each corner of the supporting frame with a small nut or block 29 preferably welded thereto. Screws 30 are threaded in these nuts or blocks, and it will be apparent that the vertical and horizontal screws of each corner of the frame 1() are offset from each other sufficiently to provide clearance therebetween. This is preferably accomplished by slightly offsetting the blocks 29 at each corner of the frame, as will be apparent. The screws 30 adjacent the heads thereof extend through openings 31 formed in the Vadjacent hollow frame members, and each screw is provided adjacent such opening with a flange 32. These flanges are placed in posi* tion after the screws are inserted and are spot welded or otherwise secured to the respective screws.'

Each of the hollow frame members may be provided with any suitable form of grooving or the like for the purpose of ornamentation and reinforcement. ln the present instance, each of the hollow frame members is shown as being provided with a groove 33 forming a reinforcing bead. lf desired, the frame members 24 may be similarly grooved for L, vthe same purpose. vWhen the device is embodied in a door structure, such structure may be provided with any suitable form of hinges 34.

The operation of the device is as follows: rlhe inner structure comprising the wire cloth and frame 10 is formed in the manner previously described by cutting the cloth to the proper size, bending the frame into the desired rectangular form, and then welding or otherwise securing the edges of the wireV to the frame 10. Thus a substantially rigid supporting structure for the wire is provided, andthe wire is held to its proper width and height to prevent buckling or distortion thereof. The rails 12 and 13 of the supporting frame are placed within the outer hollow frames 14, v15 and 16 by springing apart the lips 17 thereof a'suviiicient distance to permit the inner frame structure to pass therebetween. With the ends -of the screws 30 inserted in the nuts or blocks l29, screw,H

drivers may be applied to the head-s of the screws to' turn them and thus move the hollow frames inwardly with respect to the supporting frame 10. The corner plates are then applied in position andare held in such po-f sitionvby application of the screws 22. The intermediate frame members-24 become inserted in their desired positions with respect to the side frames 14 as the lattery are moved inwardly 'when assemblingv the de- Y vice. Outward distortion of the side frame members 14 intermediate their ends is pre vented by tightening the screws 27.

When it is desired to accurately adjust the door to the desired size, the screws27 are slightly loosened,"whereupon the screws 22 are loosened sufhciently to permit the portions of the corner pieces 18 adjacent the screw heads to be spread apart a sufficient distance to permit the end ofthe screwdriver `to be inserted into the slots of the screws.

These screws `are then turned as desired to increase or diminish the width and/or height ofthe door, whereupon the '

screws

22 and 27 are tightened. These screws positively prevent relative movement 'between the parts, althoughl relative movement at the corners of the door will be prevented by the screws 30, since these elements prevent any members. It will'be obvious that the screws 30 function either to enlarge or decrease the size of the door. When drawing the hollow frame members inwardly, the heads of the screws contact with the frame members,l
