UNITED Specification of Letters Patent.

Yatented. Nov. 13, 1906.

Application filed May 13, 1906.- Serial No. 317,661.

Longview, in the county of Gregg and State of Texas, have invented a new and useful Screen, oi which the following 13 a specification.

This invention relates more particularly to window and door screens in which metal frames are employed.

One of the principal oh ects is to provide an exceedingly simple frame structure that can be shipped and sold in knockdown condil tion and readilv assembled by the purchaser or user.

A further object is to provide a frame which will constitute an eiiective clamp for the wire-netting without the danger of cutting sue-h netting.

A still further obect is to provide sup orting or guiding means for the frame, which is adjustable in order that it may he acconnnodated to any inz'tccuracies in the windowfrsme towhich the screen is applied.

One of the embodiments of the invention. is disclosed in the accompanying drawings, wherein-- I Figure 1 is a front elevation of the screen, showing the same in place upon a window frame. Fig. 2 is a horizontal. sectional view through the same. Fig. 3 is a detail perspective view, on an enlarged scale, through one of the lower corners of the frame. Fig. d is a sectional view on the line 4 4 of Fig. 3. Fig. 5 is a detail perspective view of one of the corner-pieces.

Similar relerenee-mimerals designate corresponding parts in all the figures of the drawings.

In the emhodiment illustrated side rails (3 are employed that are composed of sheet metal, each side rail consisting of a body portion having an outer angularly-disposed merginal flange 7, the flange being doubled upon itself to provide leaves 8. An inner marginal flange 9 is also provided, which flange is doubled, as shown, and is bent back upon the bodv, the doubled free edge heiug rounded, as shown at 10. The various side rails are similarly shaped and may be of different lengths in order that different sized frames may be constructed for different Windows.

The side rails are connected. by, cornerpieces 11, which consist of angularly-disposed arms 12, the outer sides of which have outstanding longitudinally-disposed flanges 13. Tnese flan es have their adjacent ends preferahly beveled and separated, as shown at 1-1. in order to prevent the corner pieces bendin at the juncture of the arms, they are prefer-a oly reinforced by strengthening-heads 5. These beads may or may not be em- 10 ed, as desired. The arms 12 overlap the ends of the side rails. The inner margins of said arms are clamped between the inner flanges 9 end the body-strip 6 of said rails. The outer flanges 18 are clamped between the leaves 8 of the outer flanges 7 of the side rails, as clearly shown in Figs. 3 and 4.

Wire-netting 16 extends across the space defined by the frame formed as above, and

this netting has its margins doubled about the rounded edges 10 of the inner flanges 9 of the side rails, the edges of the netting being clamped between said flanges 9 and the body strips 6 of said side rails, as clearly shown in Fig. 2.

The structure as thus far described can be employed either for door or window screens. When employed for the latter purpose, guides are provided in which the screens slide. These guides are made of sheet metal, and each consists of a rear wall 17 and a front wall 18, connected to one edge and overlying said rear wall, being disposed. substantially parallel thereto. An outstanding retainingwall 19 projects from the opposite edge of the rear wall 17 in angular relation to said rear wall and the front wall being spaced from the latter, thereby forming a slot 20 and an inclosed guideway 21. Two guides employed which are secured to opposite sides of the window-frame by fasteners 22, preferably in the form of screws, that pass through the rear and front walls 17 and 18 and adjustablv connecting the same, so that by setting the screws in or out the distance between the walls may be varied. The screen is mounted on these guides by having the outer flanges 7 of the upright side rails en gaged between the walls 17 and 18 at one side of the fasteners 22, as shown in Fig. l, the side rails projecting through the slots 20.-

It will be apparent that the parts forming .the frame can be readily and cheaply manuture, the guideways being adjustable, inaccuracies in the window-frame can be readily provided for. The screen-frame has a number of decided advantages. In the first place it will be seen that the arrangement described is very simple, and different parts are made to perform a plurality of functions. Thus the flanges 7 and 9 of the side rails strengthen said rails, so as to prevent their bending. The constitute clamps for the cor her-pieces, an furthermore, the outer flange acts as a guide, while the inner flange secures the netting. This. inner flange, moreover, being doubled, as shown, provides a rounded bearing for the netting, and thereby elimihates the danger of cutting said'netting.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a screen, the combination with a guide comprising a rear wall, and a front wall carried by one edge of the same and spaced therefrom, of a fastening device adjustably passing through the walls and constituting means for holding them different distances apart, and a screen-frame having a side rail provided with an offset marginal flange that engages between the walls of the guide at one I side of the fastening device.

2. In a screen, the combination with a guide comprising a rear wall, and a front wall carried by one edge of the rear wall and spaced therefrom, and an angularly-dis osed retaining-wall carried by the outer en ge of the rear wall and spaced from the free edge of the front wall, forming a slot, of fastening devices adjustably passing through the front and rear walls and constituting means for holding them different distances apart, and a screen-frame having a side rail that pro j ects into the slot of the guide and has an offset marginal flange that engages between the front and'rear walls of the guide at one side of the fastening devices.

3. In a screen, a frame comprising side rails, each having a body portion with inner and outer outstanding marginal flanges dis posed on one side of the body portion, and a corner-piece comprising angularly-disposed arms that fit flat against the ends of the body portion and have their inner and outer side margins clamped between the inner and outer marginal flanges, one of said flanges of each rail being disposed flat against that face of comprising angularl' -disposed arms that overlap the ends of t e rails, the inner mar gins of the arms being clamped between the inner flanges and body-strips of the rails, the
