WINDOW-SCREEN.

' Patent and catches behind the' flange thereof. In

Be it known that I, JACOB S. SPEER, of order to i s rt the window screen frame Springfield, county of Green, and State of Missouri, have invented a certain new and useful Window-Screen; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention isto improve the construction of window screens and the like to render the same simple, durable and easy to manipulate and mount. The frame of said screen is of sheet-metal and the other so that there is no wood, and when the metal parts are made non-corro- I sive, the window screen is sanitary and ex- The t re of the Invention will be undertremely durable, as no part thereof can de- Stood m h a co panymgdrawmgs and cay, and it also presents an attractive aphe followmg description and clauns. penance, In-the drawin Figure 1 1s a front eleva- The chief feature of the invention con- 1 11 ofthe Wm ow screen. Fig. 2 is a per sists in taking a straight strip of sheet metal sp v V QW of the 11 and forming 1t with a pair of oppositely. exf he Scre n lpverte n v tending flanges along each edge so as to op, away, Flg. 3 1S 9. SGCtIOII on the line pose each other and leave a channel between of Fig. 1. Flg. s a perspect1ve new of them, then bending this strip so formed into n val disk- Flg. 5 18 a plan new of a a rectangular frame of the desired dimen- The edges of the wire fabric project into the channel of the frame and over the wide flange thereof which is formed with a groove. A rod is placed insaid grooveupon the fabric, and a number of oval disks, which are separate from the frame, are in serted in" the channel narrow-wise and turn by a wrench so as to wedge between the rod binding the wire fabric and the opposite This simultaneously stretches and binds securely thewire fabric, and it is very readily released by merely turning the disks slightly to loosen the same. The frame, wire fabric, binding rod and oval disks are all entirely separate from each other until assembled and then merely frictionally engage each other,'so that there are no screws, nails, springs or similar objectionable fastenings.

Another feature of theinvention consists in the means for mounting this wire screen. An arm is secured to the side of the window casing so as to project over the channeled sides of the window screen frame when inserted in the window casing, and a lever is pivoted to the projecting end of each arm with a. head turned U-shaped substantially dow screen frame is cut away at suitable polnts. releasable fastener is provided for securing the lower end of the window such operationthewindow screen will reig. 6 is a perspect' the metal strip for forming the frame out ready to be bent into position, and the bent position being indicated by dotted window casing, the upper portion of the window casing being broken away. Fig. 8 is a section on the line 8-8 of Fi 7, the screen being shown pushed outward y at the lower end by the dotted lines. Fig. 9 is an enlarged view of what is shown in the upper part of Fig. 8. Fig. lOis a horizontal section on the line 10-10 of Fig. 9. Fig. 11 is a section on the line 11-11. of Fig. 8. Fig. 12 is a section on the line 12-12-0f Fig. 11. 7 The window. screen. is provided-with a frame 10 made preferably of a strip of sheet metal formed with a-narrow. flange 11 on one side and a wider: flan e12. op'osite thereto on the other ed e, t e two anges opposing each other an therefore projecting in the same direction relative to the body of the strip. This leaves between'the two 11 is turne thereof. The narrow flan so that the extreme end of the head pr0 ects strip. The wide flange 12 is shaped like into the channel of the window screen frame molding on the outside, and therefore has aover said levers, the inner flange of the win-- per left-hand corner parts being broken 'ort-ion of the top of the window screen..

Fig. 7 is a front elevation of the screen in a,

flanges a channel extending. longitudinallg beyond a right angle to t ebody of the;

screen to the window casing. With this'conpractical;

I main suspended at its upper ends from said ve view of a portion of longitudinal groove formed by it and the I the frame with its edges lying upon the wide flange 12 and over the groove between it and the body' of the strip. Then the rods 17 are laid upon the edges of the wire fabric, one on each of the four sides. Oval disks 18 are laced in the channel and they are provide with rectangular holes 19 for the insertion of a tool or wrench for turning same and are made of such dimensions that the narrow diameter is less than the space between the rod 17 and the flange 11 of the frame, while the greater diameter is slightly in excess of said distance, so that the disk can readily be inserted and turned and wedged ti htly in the channel between the rod 17 an the flange .11 of the frame. In order to strengthen the hold of said disks, they are beveled on the periphery, the wider side of the disks being placed against the body of the frame, and since the flange 1'1 overhangs somewhat, they will not escape from said flange nor from the rod, as they tend to press the rod outwardly somewhat against the flange 12 and wedge in between said rod and the body of the frame. There fore, the essential part of the window screen I consists of the channeled frame, the wire fabric, the rods 17 and the disks, all independent of each other before amemblage and each made of metal, and the parts may be easily assembled and as easily separated. This makes the window screen very simple and durable, especially when the metal parts are made non-corroslve as they should be. And the window screen, as a whole, is superior to the ordinary wooden framed screens.

On one end there is a cover plate 21 adapted to close the space between the top of the window screen and the window sash. It has in it transverse slots 22 for screws 23 which extend from the frame 10, whereby the plate 21 is adjustably secured in place to accommodate itself into a particular window casm 25 1s a window casing and on each side an I arm 26 is secured that projects outwardly at an upwardly inclined angle to point in front of the channel of the frame. On the outer end of said arm a lever 27 is pivoted between its ends, one end being relatively long to be manipulated and the other end formed into a head that is first bent at a right angle from the body of the lever so as to project into the channel of the window screen when in place,

see Fig.- 10 and the extreme end of the head is turned laterally so as to project behind the flange 11 of the window screen frame when in place. This makes the head of the lever substantially U-shaped. The flange 11 of the window screen frame is cut away at 28 so that said frame may be placed over the heads of said levers in Inserting the window screen into the casing. Then the window screen frame is lowered somewhat to the limit, said holding devices bein located at the upper end thereof and the levers actuated so that the heads thereof firmly bind the frame of the window screen frame against the window casing and hold the same tightly in place.

The lower end of the window screen frame is held in position by the catch lever 30 which is pivoted to the lower part of the window casing .by the pin 31 and has one end lengthened for manipulation and on the other end there is a laterally bent head 32 adapted to enter the channel of the frame of the window screen and bind the flange 11 thereof against the window casing.

For letting flies or dust out, the lower fastening may be disengaged and the lower part of the wlndow screen pushed outwardly. During that operation the window screen will be suspended from the heads of the levers 27 above. The window screen can be then pushed back and fastened on the lower fastener.

What I claim as my invention and desire to secure by Letters Patent is:

1 A window screen including a frame provided with two longitudinally. extending opposing flanges with a channel between them, a abric with the edges thereof extending into said channel against oneof said flanges, a rod, in and extending longitudinally of said channel and resting upon the fabric, and means in said channel adapted to wedge between said rod and the opposing flange of said frame for securing the fabric to said frame.
