UNITED STATES PATENT OFFICE.

ARTHUR L. OTTO, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO ORANGE SCREEN COMPANY OF MAPLEWOOD, NEW JERSEY, A CORPORATION OF NEW JERSEY.

IMIIEITAILLIC SCREEN.

My invention relates to a certain rew and useful construction in metallic screens for windows, doors and .the like, whereby a solid and integral metallic screen frame structure is produced, which will be in the true sense of the word a single unitary structure without any mechanical or visible joints or seams of any kind, being in effect .a continuous metallic structure throughout the periphery and the frame and which frame moreover will be provided with suitable screen retaining grooves or recesses or channels, as well as suitable channeled, solid or rounded outer edges. to adapt the same for various uses to which such screens are put, namely to adapt the same to sliding as well as to hinged screens for windows, doors and the like.

With the above ends in view my invention consists of a certain new and novel metallic screen, and the method of making the same, whereby the frame is produced which is much more serviceable, durable and rigid than metallic screen frames produced heretofore, and which in addition to the above advantages-are far more attractive in appearance than the screens and screen frames known heretofore, which have been made exclusively of sheet metal.

My invention further consists of a novel method of making metallic screens. and screen frames which consists in extruding through'the suitable dies 9. solid metal, screen retaining channel piece, severing said screen retaining channel piece into suitable lengths with mitred ends, welding or fusing such ends together to form suitably sized and shaped integral, unitary and continuous metallic screen frame, having a suitable screen retaining channel along the inner edges of one of its faces. Aluminum or aluminum alloy is preferred for the screen retaining channel pieces, since in addition to lightness they impart other advantages to the screen frame, as will be brought out hereinafter.

My invention further consists of a nove screen frame structure which in addition to being possessed of extreme stren h and rigidity, will also be light and which will be provided with novel screen retainin'g means within said inner screen retaining channels, for replaceably securing metal screening to the frame.

It has been customary heretofore in making metallic screen frames, to shape the frame members out of strips of bendable sheet metalybending the sheet metal back upon itself into various complex cross sectional shapes in an effort to obtain a rigid structure. Due to the very nature of the construction, however, no screen frame of any considerable size could be produced sufficiently rigid without the use of some reinforcing means. This was particularly noticeable in the case of the mitred corner joints, which heretofore have been soldered along the thin contacting edges of the sheet metal, and in addition to the soldered joint, have been .braced in some manner. This construction, however, gave results not entirely satisfactory, and particularly so in screen frames of largezproportions in which case the screen was subject to distortions.

By my present invention moreover, an extruded metallic screen frame may be provided having screen retaining channels in a face thereof, of substantially uniform crosssection and having the walls thereof substantially parallel, and having a substantially parallel walled anchoring member seated in said channels. adapted to secure the edges of a screen fabric therein, without the aid of any positive interlocking means, such as the interlocking of the splines in the inwardly enlarged screen retaining channels employed in the built up sheet metal screen frames of the prior art, used extensively heretofore.

This securing action between the screen cloth,'pressed flatly, and relatively lightly,

against the inner surface of the channel, with the dislo dging force acting at a right. angle to the line of extrusion of said frame members and said channel, is due partly to the interengagement obtained between the apparently and relatively smooth extruded surfaces of the channel and anchor member on one hand, and the raised or high intersecting points of the wires of the screen cloth and the series of minute, parallel longitudinal ridges and furrows, the

grain of the metal, on the other hand, w ich are formed in the apparently smooth inner walls of the channel'as a result of extrusion, longitudinaly of, and parallel to, said channel.

This novel lockin action between the relatively smooth walls of the channel and the anchor member and screen cloth, may further be augmented, by extruding the frame members of a relatively malleable and yet rigid and strong metal, such as aluminum or an aluminum alloy; since by such novel means a further locking action is obtained, by the gradual embeddin of the raised or high intersecting points 0 the wires of the screen cloth, in the inner surface of the screen retaining channel.

For the purpose of illustrating my invention, I have shown in the accompanying drawingsforms thereof which are at present preferred b me, since they will give in practice satis actory and reliable results, although it is to be understood that the various instrumentalities of which my in vention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Referrin to the drawings in which like reference 0 aracters indicate likeaparts.

Figure 1 represents a perspective view of a corner section of a novel screen frame structure embodying my invention.

Figure 2 represents a perspective view of a corner section of a modified form of a novel screen frame structure embodying my invention.

Figure 3 represents a similar erspective view of a corner section illustrating a third modification of my novel metallic screen.

Figure 4 represents a horizontal sectional view of a novel screen frame embodying my invention, on the line 4-4 of Figure 1, composed of vertical stiles of the construction shown inFigure 1, a top rail of the construction shown in Figure 2, and having abottom rail of a constructionshown in Fi ure 3, all integrally united.

Figure 5 repersents a modified section of a rail similar to that shown in Figure 2, having a rounded outer edge.

Figure 6 represents a modified section of a rail similar to that shown in Figure 3, rounded at the outer edge.

Figure 7 represents a section of a rail similar to that shown in Figure 3, illustrating a modified means of securing a screen to the frame, which is'adaptable to any one of the rails or stiles shown in Figures 1, 2, and 3.

Referring to Figure 1 of the drawings, 1

. designates a rail or stile of my novel metalhe screen which is formed by extruding a suitable metal through a properly shaped die, in a hot and plastic condition. The stile 1 shown in Figure 1, is adapted chiefly to vertically sliding screens, and consists of the inner screen retaining recess or channel 2, along the inner edge thereof, a guiding channel or recess 3 along the outer edge thereof, and a plurality of central webs 4 and 5 between the guiding channel 3- and the screen retaining channel 2. The screen 6 extending over the frame 7, is secured at its edges by means of the locking strip 8, which is an inverted U shape metallic channel strip, by forcing said inverted U-shaped anr-horing'strips into the screen retaining channel 2, as shown in each of the Figures 1, 2. and 3, over the edges of the screen 6. thereby locking said screen within said screen retaining channel 2.

If desired all four sides of the frame 7 may be formed of the rail 1 shown in Figure 1, by uniting mitred ends of said rails by means of welding or fusion, thus producing continuous, integral and solid metal frame structure. Instead of using the rail lshown in Figure 1, I may use as the top and bottom rails of my screen frame, or possibly only as the top rail, the rail 14 shown in Figure '2 of the same outside dimensions as that shown in Figure 1, havouter guiding channel 3 when such is not desired as at the top rail.

It added rigidity is desired, as in the case of the lower rail 12 of the frame, it is within the scope of my invention, to make the body portion 13 of said rail or stile solid, as-

shown in Figure 3, thereby imparting greater rigiditv-and strength to such memer. a

' In constructing the metal screen frame according to my invention, I may avail myself of any one, several, or all of these rails shown in Figures 1, 2', and 3, to produce the said continuous and integral structure shown in Figure 4, having thebottom rail 12 and the top rail 14, andthe

stiles

15 and 16 in the embodiment of my invention shown in Figure-4.- .The bottom rail 12 is provided with the solid body 13, shown particularly in Figure 3, while the top rail has the hollow body 14 as illustrated in Figure 2, while the side stiles are provided with the outer guiding channel 3, as illustrated in Figure 1. Figure 4 shows very clearly the method of uniting the various stiles and rails into at Figure 4, I may provide for the stile members, such as shown in Figures and 6,

having the 'body portions 13 either hollow or solid as shown in Figures 5 and 6 and having outer edges 19 rounded so as to produce a close fitting joint along the hinged edge in any position of the frame.

I may also provide a second modified form of a screen locking and anchoring device 20, within said screen retaining channels 2, consisting of a spline 20 of substantially rectangular form or cross section, and having a groove 21 along one side thereof, which is engaged by a series of set screws 22 along the length of said rails and stiles, extending through and threaded into the central webs 4 or 5, or bein passed through threaded openings 23, wit in solid body portions 13, in which case said body portions are recessed as shown at 24 so as to receive the head 25 of said set screw.

It is thus clearly seen from the above description that the screen of my novel construction embodies a number of distinct advantages; among them, the extreme strength and resistance of the frame members,

. against any force tending to crush the same,

less light and air when in position, and

being of. neater design and less consplcuous. The general appearance of the completed screen is further enhanced by the fact that no ]oints are visible.

The solid metal construction possesses the further advantage that some of the metal of the body portions 13 may be removed without materially impairing the rigidity of the frame. This is of particular utility when small adjustments in size of the finished frame are necessary to correct for errors in measurement, as well as in cases where parts of the frame must be cut away to clear obstructions on the sill, such as shutter fasteners. Such alterations and adjustments by removing part of the metal are impossible with sheet metal screen frames, since any removal of metal of any frame member will materially impair the strength of the same. 1
