DOOR AND WINDOW SCREEN AND MEANS FOR SECURING WlRE-GAUZE IN SCREEN-FRAMES.

SPECIFICATION forming part of Letters Patent No. 388,870, dated September 4, 1888.

Application filed August 10, 1887. Serial No. 246.591. (So model.)

To all wit-0112, it may concern.-

Be it known that I, Esrrnrnron HIPOLI'IO, a citizen of the United States, residing at Los Angcles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Door and Window Screens and Means for and the Art of Securing Wire-Gauze in Screen-Frames, of which the following is a specification.

Various means have heretofore been employed for securing the wire gauze in the frames of door and window screens, among which may be mentioned that of inserting the edges of the sheet of gauze in grooves cut into the frame and securing the same by means of nails driven through the frame and the meshes of the gauze. This is a very desirable manner of constructing the screen, as it gives a neat appearance, both sides of the screen appearing the same. Much difficulty has heretofore been experienced in constructing the screens in this manner, as no process had been devised whereby the gauze could be stretched perfectly tight, and it was found necessary to use a large number of nails to hold the gauze and stretch it evenly. It is also found that no matter how closely together the nails may be driven to hold the gauze, the wires will bend whenever any strain is brought to bear upon the gauze to stretchit, and that the gauze cannot be stretched perfectly tight. It is also a difficult matter to insert the edge of the gauze into the slots of the frame.

The object of my invention is to avoid these diiiiculties and to so construct my screen that the gauze may easily and conveniently be in sorted intothe grooves in the frame; also, to provide means for securing the gauze perfectly, so that it may be stretched evenly and tight; also, to devise a method of inserting the gauze in the grooves and a method of stretching the gauze perfectly. I accomplish these objects by the means and in the manner described herein, and illustrated in the accompanying drawings, in which- Figure 1 is a plan elevation of my improved screen as it appears when partially put together, as will be more particularly set forth hereinafter. Fig. 2 is a corresponding view showing the screen as it appears when ready to stretch the gauze. Fig. 3 is a cross-section of Fig. 2 on line 0 Fig. 4 is a cross-section of Fig. 1 on line y y. Fig. 5 is an enlarged View of a portion of Fig. 3. Fig. 6 is a detail view ofa portion of one corner of the gauze, showing the arrangement of the strips of tin. Fig. 7 is a view of the sheet of gauze as it appears before it is bent over the tin strips. Fig. 8 shows the gauze as it appears when it is bent over the tin strips and is ready to be inserted in the grooves. Fig. 9 is an end view of one of the end pieces. Fig. 10 is a view of the tin strips which form the frame over which the tin is bent. Fig. 11 is a view of one of the side pieces, showing groove I).

The frame of the screen is composed of the end pieces, A A, and the side pieces, B B, each provided with a tongue, 0, extending from end to end of the inner side thereof. Grooves D extend along the tongues from end to end, as shown in Fig. 11. A groove, E, extends across each end of each end piece.

I prepare the wire-gauze S by first cutting it to the size desired, which is about one and a half inch larger than will be required to exactly fit into the recess formed by the grooves D D D D when the frame is put together. I then clip off the corners at an angle of fortyfive degrees with the sides and ends of the gauze, as shown in Fig. 7. I then provide the tin strips F F F F, which are beveled at their ends, so as to fit together to form a frame. I lay these strips upon the gauze, placing the beveled ends together, as shown in Fig. 8, and I then bend the ends and sides of the gauze over upon the tin, as shown in Fig. 8. I then slip the end of the screen thus formed into the groove D in one of the end pieces, allowing the gauze to extend beyond the ends of the end piece to the same extent on both sides, so that the gauze may be inserted to the same extent into the grooves in the side pieces. I then secure the gauze in the grooves by means of brads G, driven into the Wood and through the tin and gauze, as illustrated in Fig. 5. The other end piece is then secured to the other end of the gauze in the same way. I then slip one side of the gauzeinto the groove in one of the side pieces, B, bringing one end of the side piece flush with one of the end pieces, A. The two pieces are then secured together with a nail or screw,

H, as shown in dotted lines, Fig. 1. The other side of the gauzeisthen slipped into the groove in the side piece 13 until one end of the side piece is flush with the end piece A, as shown in Fig. 2, when it is secured to A by a nail, II, (shown in dotted lines,) in the same manner as the other side piece. I then clamp the side pieces firmly by the clamp I, and then drive the end piece A toward the ends of the side pieces until it becomes flush therewith, the edge of the end piece beingin the position shown by the dotted lines at the top of Fig. 2. This tightens the gauze endwise. The nails H H are then driven into place, thus finishing the frame. Brads similar to G are then driven through the side pieces and the gauze and tin at intervals, as shown by J, which indicate points where the brads may-be driven. This completes the screen, and I then remove the clamp, thus releasing the strain upon the side pieces. If the clamp is set sufficiently tight,it will bend the side pieces so that when it is removed the straightening of the side pieces will tighten the gauze sidewise. In this manner the gauze is lightened in each direc tion. It will be observed that as the gauze is doubled over the tin and then inserted in the groove and securely nailed there is no lateral strain on the wires, all the strain being borne by the wires which are bent over the tin.

It is obvious that the tongues O and grooves E are not absolutely necessary for the operation of my invention, as they might be dispensed with without making the frames uscless. They aid materially in putting the frame together and serve to strengthen the frame; but I do not wish to limit myself to their use.

It is also obvious that strips of any material which will serve the purpose may be substituted for the tin strips F F, and that the ends may be allowed to lap or may be cut off so as to not touch each other. The dotted lines in Fig. 10 suggest forms of]? and F which may be used instead of the form I have adopted as the best. Screws or other fastenings may also be used in place of the brads and nails shown. It is also obvious that my invention may be employed in constructing screens formed of material other than wire-gauze,such as leather or cloth.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a window-screen, the combination, with a loose extensible frame, F, of a sheet of gauze applied thereto, a second frame adapted to receive the gauze and its frame, and fast enings for securing the parts together after the gauze has been stretched.

2. In combination with a loose extensible frame, a screen sccu red thereto,a supplemental frame grooved on its inner edges to receive the loose frame and screen, and fastenings adapted to secure the parts together after the screen has been stretched.

3. In combination with a loose extensible frame,a screen secured thereto, asupplemental frame tongued and grooved, substantially as shown, and grooved on its inner face to receive the loose frame and screen, and fastenings adapted to secure theparts together after the screen has been stretched.

4. In combination with a loose extensible frame,ascreen secured thereto,asupplemental frame grooved on its inner edges to receive the loose frame and screen, and fastenings passed through the loose frame, the gauze, and into the main frame after the gauze has been stretched.

5. In combination with an extensible frame, as F, a screen secured thereto, a second frame grooved on its inner edges to receive the extensible frame F and comprising the parts A A and B B, the parts B B being of a length greater than that of the screen, fastenings securing the screen to the parts A A, fastenings securing the parts A B B together, and suitable fastcnings adapted to secure the part A to the parts 13 B after the same has been moved outward into proper position to stretch the screen.

6. In combination with an extensible frame, a screen secured thereto, and a supplemental frame adapted to receive the screen and its frame, the supplemental frame being larger than the extensible frame and secured to the latter after the screen is stretched.
