Eiiaasaa'.

To all whom it may concern:

Be it known that I, GEORGE G. BUNGER, a citizen of the United States, residing at Eskridge, in the county of Wabaunsee and State of Kansas, have invented a new and useful Screen-Frame, of which t'hefollowin'g is a specification. I This invention relates to improvements in screen frames. I

An object of the present invention is to provide a novel and advantageous form of frame for a screen which may be used as a window or door screen or in like capacities. A further object of the invention is to provide a metallic frame which will be simple in construction .and light in weight and which is longitudinally and transversely adj ustable so as to conform to windows or door frames of different sizes.

A still further object of the invention is to provide a metallic frame'including hollow metallic members, each of which is formed from a single strip of material bent into polygonal form with the overlapping edges arranged as the inner side walls of the member, and adapted to receive the foraminous screen thereunder and to secure and hold the same in place, and at the same time allowing it to be readily removed and re placed from time to time.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings accompanying this specifi'cation and forming a part thereof, the preferred embodiment of my invention is illustrated in which.-

Figure 1 is a front view in elevation of my improved screen frame. Fig. 2 is a sectional view taken on the line 22 of Fig. 1. Fig. 3 is a sectional view taken on the line 33 of Fig. 1. Fig. 4 is a perspective View of the upper cross bar. Fig. 5 is a perspective View of a portion of one of the side bars. Fig. 6 is a fragmental view in perspective of a portion of the center bar with its outlying angle braces which are formed integral therewith.

Referring to the drawings in which simi- Speciflcation of letters Patent. I .lPa tentnedl Apr. 1T3, T9155. Application filed May 20, 1914. Serial No. 839,869-

ing parts throughout the several views, the screen frame includes a pair of spaced side bars 7, which are formedby folding a single length -of metal into box-like shape and with lar reference numerals indicate correspondthe overlapping edges 8 and 9 arranged as 4 the inner side walls of the frame. The upper and inlying edge 9 is serrated as at 10 so as to-constitute a grip for the :foraminous cloth or wire screen and hold the same in a stretched or taut condition. The extremities'of the box-like sidebars are removed or open as at 11, as indicated by the dotted lines in Fig. 5.

Upper'and lower cross bars 14 are formed similar to the side bars, and include over-' lapping edges 8 and 9 and the serrated edge 10 corresponding to the portions of the side bar represented by the analogous and unprimed numerals. Each cross bar as illustrated in Fig. 4, is provided with the bent end or tongue 15, the said. tongue or end wall being slightly narrower than the space intermediate the walls of the bar so that a space or groove 16 will be defined'between the edges of the end wall 15 and adjacent portions of the bar. The cross bars are thus adapted to fit down over the side bars and to receive the upper extremities of the side bars within the open or removed portions 18, and in order to brace the entire structure and to hold the parts in interlocked relation, the tongues 15 extend within the side bars as will be apparent from reference to Fig. 3,

thus providing that the outer walls of the side bars will present a continuous unbroken surface which is necessary for the proper working of the frame which can be used either for window or door screens.

The side bars 7 and upper and lower cross bars 14 are provided with the longitudinally or axially extending

slots

13 and 19 which register and receive the securing bolt 20 therethrough. The nut 21 looks the bolt rigidly in place and exerts the requisite force necessary for the rigidity of the screen contact with and rigidly gri pi th .f 1 raminous cloth or wire screen 21. In order to brace the frame, the center cross bar 22 is provided and as illustrated in detail in Fig. 6, includes the front member 23 withthe upturned flanged edges 24. Coacting with the foregoing, is the rear member 27 which is U-shaped in" construction and with the side walls 28 serrated and extending between the flanges-24 of the front member. The front and rear members therefore, coact to form a box-like structure similar to the formation of .the side and upper and lower cross bars heretofore described. In order that the ends of the central cross bar may embrace and engage the side bars 7, the ends of the flanges 24 are removed as at 25 and the slots 26 provide for thesecurement of the cross bar to the side bars. The side walls 28 are cut adjacent the ends of the central cross bar and are bent outwardly to form. angle bracing members 29. The bracing members are twisted about the longitudinal axes as at 30 soas to bring their outer extremities in a planecoincident with the plane of the front and rear, walls of the side bars to which they are secured. The. angle braces are provided with the slots 31 which receive the bolts 33 therethrough, the latter extending through suitable transversely extending slots provided in the side bars 7. Suitablebolts 33 extend through the slot 26 of the side bars and hold the frame in a rigid manner. A bolt 34 extends cent-rally through the cross bar' 22. anddraws the front and rear members thereof, into telescoped relation so that the serrated edges will rigidly grip the foraminous cloth or wire screen.

The foregoing points out a metallic screen frame which will be light in weight and yet will embody a considerable amount of strength and the requisite rigidity. The box-like shape of the various side and cross bars in addition to providing a maximum strength with a minimum amount of material and therefore comprehending a minimum amount of weight defines a bar adapted to receive and conceal the ends of the screen 21 therein and due to the overlapping and serrated edges, rigidly hold the same so-positioned. The longitudinal slots with which the various side bars and'cross bars are provided, allow. the frame to be transversely and longitudinally adjusted and the manner in which said bars are interlocked preserves the continuity of the outer edges of both the side and cross bars. This therefore eliminates all projections and insures the easy and smooth sliding or swinging movement of the frame with relation to a door or window as the case may be. What is claimed is:

1. An article of the class described, comprising hollow side bars, and upper and lower cross bars, said cross bars being provided with end walls spaced between the side walls of the cross bars, said end walls fitting within the side bars, the side bars and cross bars being provided with overlapping inner edges, the inner of the overlapped edges being provided with serrations adapted to grip a foraminous material.

2. An article of the class described, comprising hollow side bars, upper and lower cross bars, said cross bars being provided with end walls spaced between the side walls of the cross bars, said end walls being positioned within the side bars, the side bars and cross bars being provided with overlapping inner edges, the inner of the overlapped edges being provided with serrations adapted to grip a foraminous material, and means engaging the cross and side bars adjustably holding the same together.

3. An article of the class described, comprising hollow side bars, upper and lower cross bars, said cross bars being provided with end walls spaced between the side walls of the cross bars, said end walls being positioned within the side bars, the side bars and cross bars beingprovided with overlapping inner edges, the inner of the overlapped edges provided with serrations adapted to grip a foraminous material, said side and cross bars provided with axial slots, and means extending through said slots for holding the cross and side bars to gether and providing for the longitudinal and transverse extension of the frame.

4. A screen frame comprising side and upper and lower cross bars, each cross bar substantially box-like in cross section and provided with overlapped edges upon the inner side walls, said overlapping edges being provided with serrations extending therealong and adapted to grip the ends of a screen and house the same therein, the upper and lower cross bars being provided with tongue like end Walls extending within the side bars, means for locking the side and upper and lower cross bars in adjusted positions, and a central cross bar provided with outlying angle braces formed integral therewith and provided with means for gripping the wire screen throughout substantially the entire length.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
