CARL E. BOWER, OF BETHEL, MISSOURI.

WINDOW-SCREEN.

To all whom it may concern:

Be it known that l, CARL E. Bownn, a citizen of the United States, residing at Bethel, in the county of Shelby and State of Missouri, have invented new and useful Improvements in Window-Screens, of which the following is a specification.

The invention relates to window screens and has for an object to provide a screen that can be varied in length and width in order to adapt the screen for use in connection with windows of various sizes and dimensions.

The invention embodies, among other features, a frame adapted to carry the usual screen wire and which consists of sides and ends which are relatively adjustable and connectible, and brace members for use in connection with the said sides and ends to secure the same in relatively rigid position.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a side elevation, showing the side and end members in position prior to assembling the same; Fig. 2 is a vertical 1ongitudinal sectional view taken through the screen frame, showing the sides and ends in initial position; Fig. 3 is a similar view showing the sides and ends in final and secured position and the brace members arranged in tightened and secured position; Fig. 4 is a side elevation of the completed screen, the dotted lines indicating the parts that have been removed from the sides and ends, the other dotted lines indicating the final positions of the brace members; Fig. 5 is a fragmentary perspective view of one of the sides; Fig. 6 is a fragmentary perspec tive view of one of the ends; and Fig. 7 is a perspective view of one of the brace members.

Referring more particularly to the views, I disclose a screen 10 comprising side mem: bers 11, 12, the side member 11 having a channel 11 provided in one end thereof and a tenon 11 formed at the other end thereof. Similarly, the side member 12 is provided at one end with a channel 12 and at the other end with a tenon 12 the channel 12 however, being formed in the side member 12 on that end of the side member opposite to the end of the side member 11 having the tenon Specification of Letters Patent.

11 so that the channel 11 of the side member 11 will be opposite to the tenon 12 of the side member 12 and the channel 12 of the side member 12 will be opposite to the tenon 11 of the side member 11. The end member 13 is provided at one end thereof with a channel 13 and at the other end thereof with a tenon 13 and, similarly, the end member 14 is provided at one end thereof with a channel 14 and at the other end thereof with a tenon 14 the channel 13 in the end member 13, however, being opposite to the tenon 14 of the end member 14 and the channel 14- of the end member 14 being opposite to the tenon 13 of the end member 13. It will now be seen that when the side members 11 12 and end members 13, 14 are arranged in the position shown in Fig. 1, the tenon 11 of the side member 11 will be adjacent the channel 14 of the end member 14, the tenon 12 of the side member 12 will be adjacent to the channel 13 of the end member 13, the tenon 13 of the end member 13 will be adjacent the channel 11 of the side member 11 and the tenon 14" of the end member 14 will be adjacent to the channel 12 of the side member 12, it being understood that the tenons 11 12", 13 and 14 are, therefore, adapted to fit into the respective channels 14*, 13 11 and 12 of the respective end members 14, 13 and side mem bers 11, 12. The channels 11, 12, 13 and 14 are similarly formed in the respective members 11, 12, 13 and 14, and the channels are open at the ends of the said members and along the inner edges thereof. Now when the side members 11, 12 and end members 13, 14 are connected as shown in Fig. 2, with. the tenons of the respective side members fitting into the channels adjacent which the tenons lie as shown in Fig. 1, it will be seen that a portion 14 of the channel of the end member 14 will project beyond the side members 11, and, similarly, a portion 13 of the channel of the end member 13 will project beyond the side member 12, while a portion 11 of the channel of the side member 11 will project beyond the end member 13 and a portion 12 of the channel of the side member 12 will project beyond the end member 14.

\Nl1811 the side and end members 11, 12 and 13, 14 have been arranged as mentioned, this being the desired size of the finished screen, the projecting portions 11, 12, 13 and 14 of the respective members 11, 12, 13 and 14 are cut or sawed off from the said members so that the channel ends of the side members 11 and 12 will lie fiush with the outer edges of the end members 13, 14 and, similarly, the ends of the end members 13, 14 will lie flush with the outer edges of the side members 12 and 11 respectively. Brace members 11 12 13 and 14 are now employed for use in connection with the heretofore mentioned channels 11 12, 13 and 14 and when the side and end members 11, 12, 13 and 14 have been arranged in adjusted and connected position as shown in Fig. 2 and as described heretofore, portions are cut off of the brace members 11 12 13 and 14, the said portions being equal to the portions 11 12 13 and 14 cut off of the channel ends of the respective members 11, 12, 13 and 14, and it will thus be seen that when this has been accomplished the brace members 11 12 13 and 14 will snugly fit in the channels 11, 12*, 13 and 14 with the brace members interposed in the channels between the members in which the channels are formed and the tenons of the adjacent members and which repose in the channels, it being further seen that each of the brace members 11 12 13 and 14 has one end beveled and the inner ends of the channels are likewise beveled in order that the brace members can be snugly placed in the channels and properly secured therein. Nails or screws 15 are now arranged to pass transversely through the channel ends of the side members and end members and through the respective tenons reposing in the channels of the side members and end members, thus securing the ends of adjacent side members and end members, after which nails or screws 16 are passed through the channel ends of the side members and end members and through the brace members in the channels to rigidly secure the brace members therein, thus completing the screen 10, it being understood that the usual screen wire employed on the screen can be tacked or otherwise secured thereon after the frame has been adjusted to the proper size in the manner mentioned heretofore. Now in order to permit of great accuracy in assembling the side and end members, the side and end members, after being arranged in connected position to provide a frame of the desired size, can be first nailed together, after which the projecting portions 11, 12, 13 and 14 are cut or sawed off, and then it will be only necessary to place the brace members 11 12 13 and 14 in the respective channels 11, 12 13 and 14 and secure the same therein to complete the screen.

From the foregoing description it will be seen, therefore, that I provide a screen which can be varied in both length and width in order to provide a finished screen adapted for the particular window or sash for which it is intended, this result being accomplished without a great waste of material and without the use of skilled labor and high grade tools. It will also be seen that when a screen is completed in the manner mentioned heretofore the same screen can again be made smaller in both length and width by simply removing the brace members, adjusting the side members and end members to the desired position and again sawing off the projecting portions, the portions of the brace members being then also sawed off therefrom, after which the brace members are returned to position within the channels and secured to the respective members thereof.

Having thus described my invention, I claim:

1. A screen frame comprising four similar members, each provided with a longitudinal channel opening at one of the ends of each member, a tenon formed integrally with each member and at one of the ends thereof and fitting into the channel of an adjacent member, whereby the distance between parallel frame members can be varied, and brace members for insertion in the said channels between the tenons and in clined walls of the channels for securing the members in relatively rigid position.

2. A screen frame comprising pairs of similar side members and end members, with each of the said members having a longitudinally extending channel formed in one of the ends thereof, with one of the walls of each channel inclined and the channels opening through an end of each of the members, tenons formed with the said side members and end members, with the tenons in the end members adapted to extend into the channels of the side members and the tenons of the side members adapted to extend into the channels of the end members, whereby the members in each pair may be arranged in relatively spaced relation so that the distance between the members in each pair can be varied, and brace members having inclined edges and adapted for insertion in the said channels and interposed between the said tenons and the solid portions of the said members.

In testimony whereof I afiix my signature in presence of two witnesses.
