MILLAR, on LAMBTON, ONTARIO, CANADA, As- SIGNORS TO THE WASHIBURN COMPANY, or WORCESTER, MASSACHUSETTS, ACOR- PORATIOIN' OF MASSACHUSETTS V WINDOW SCREEN Application filed October 21, 1931, Serial No. 570,165, and. in Ganada March 19, 1931.

The present invention relates to window screens which are adjustable for various sizes of windows. It is especially desirable in screens of this type in order to facilitate man- 5 ufacture and assembly of the screens, that the individual sections of the screens be similar, and that the completed sections bereadily connected together for use and it is accordingly an object of the present invention to provide window screens which incorporate these advantages. According to the invention, the individual screen sections are duplicates and are provided on opposite edges with channels and slides which inter-engage with channels and slides on the other section of each pair of screens. The slides and channels are so arranged that the individual sections may be directly connected together in their completed form to provide a completed screen without the necessity for further structural changes. Other and further objects and advantages of the invention will appear from the following detailed description takeniir connection with the accompanying drawing in which Fig. 1. is a perspective view of an assembled screen partly in section, with portions of the screening removed.

Fig. 2 is a cross-section on the line 22 of Fig. 1.

Fig. 3 is a cross-section on the line 33 of Fig. 1. p Fig. 4 is a perspective view, partly in section, substantially along the line 4-4 of i Fig. 1.

Fig. 5 is a perspective view of a portion of one of the screens.

Fig. 6 is a plan view of an edge of the completed screen.

Like reference characters refer to like parts throughout the drawing. Referring particularly to Fig. 1, the complete screen is made up of a pair of sections A and B which are each identical in construc- 5 tion. Because of the similarity of construction correspondingreference characters are applied to corresponding parts of each section and a description of one section will suffice for both. Each section consists of longitudinally extending top and bottom frame members 1, an outer end member 2 and an inner end member 3. l The outer edge 4 of the end member 2 is folded over into engagement with the main portion of said member and the outer ends of the top and, bottom frame members 1 are clamped between said folded edge 4 and the main portion of member 2.

Similarly, the outer edge 5 of the end member 8 is folded over into engagement with the main portion of said member 3, and clampsbetween said folded edge and the main'portionof said memberth-e inner ends ofthe members 1, to form with the top and bottom members 1 and the other end memher 2 the completed frame for each screen section.

As shown in Fig. 1, the screening material 6 which covers the frame is applied to the outer face of the section A and is secured at its opposite ends between the folded over edges 4 and '5 and the main portions of the members 2 and 3, the screening is also secured along its longitudinal edges to the frame members 1 by tongues 7 integrally formed with said frame members, said tongues 7 being displaced from said members and subsequently bent into engagement with the edges of the screening 6 (Figs. 2 and 3).

A pair of the individual screen sections A and B, above described, are arranged to be attached together to form a complete screen and to slide relative to oneanother, whereby the complete screen is adaptable to difierent widths of windows. To this end, the outer edges of the top and bottom frame members 1 of each screen section are provided respectively with channels 8 which extend the entire length of the members, all the channels 8 having the same cross-section. Referring particularly to Figs. 2 and 3, each channel 8 is offset from the plane of its member 1 with a rebent outer edge 9 lying substantially in the plane of the member 1. The inner end member 3 of each frame is provided at oppositeends, beyond the ends of the folded edge 5, with slides 10, which form extensions of said end member 3 and said slides 10 being bent to correspond substantially to the crosssection of the channels 8 may enter and slide within the channels 8 of opposed frame members 1, when two sections A and B are assembled.

:In assembling a pair. of-screen sections to form a completed screen, one section A with its slides 10 projecting from the left hand side thereof is placed upon the oppositely facing section B with its slides 10 projecting from the right hand sidethereof. In this position, the frame members 1 of the upper sec tionA are alined with the frame members 1 of. the lower section B, with the channels 8 in. opposed relation and the edges 9 abutting. 'Thus, the slides 10 of each section are in register with the channels f the opposed section. As indicated in dotted lines in Fig. 1,-the end member 3 of the upper screen section A in this initial assembling position projects beyond the end member 20f the under screen section B, with the outer edge of member 2, sectionB, substantially coinciding with the inner edge of the member 3 of the upper section A. Similarly, the end member 3 of the lower section B projects beyond the end member 2 of the upper section A, the inner edge of the member 3, section B, coinciding substantially with the outer edge of the end member 2, section A. From this initial position, movement of the. sections A and B relative to one another in the plane of the screens permits the slides 10 which, as above stated, are in line with the opposing channels 8 to enter said channels. A completed screen, the sections of which are securely held together, as shown in Fig. 1, is thus formed.

-Movement of the screen sections A and B in extending or lengthening the screen during adjustment thereof, is limited by. engagement of the inner edge of the end member 3 of one section with .the opposed inner edge, of the end member 3 of the opposite section, as will be clear from a consideration of Fig. 1. After the screens have been assembled, protuberances or punched stops 11 are provided adjacent the outer ends of either or both of the longitudinal members 1 '.of one section (B as shown) in a position to engage with the slides of the opposite section A of the completed screen, thereby to prevent unintended separation of the screen section's during shortening or collapsing of the screen.

From the foregoing, it will be noted that each screen section is identical in construc- 131011 with the other section and that the channels and slides are integral with the frame members formlng the screen, the arrangement being such that the sections may be in dependently formed and completed before said sections are assembled to form the comnels formed along opposite longitudinalv sides, cross strips connecting the adjacent ends of the said sides, slides formed on the opposite ends of one of said cross strips of each frame for engagement with the chane nels of the other frame and a projection integral with one of said frame'me'inbers 'for' engagement with a slide on the other frame to limit the relative'movement of the-frames in one direction.

2. An adjustable screen comprising a pair of similar frame members consisting of side and end members connected together, said side members each having'achannel integrally'formed along the outer edge thereof, slides formed on the extremities of one of the end members of each frame for engagement in the channels of the other frame, portions of the slides of one frame member being in alinement and engageable with portionsof the slides of the other frame member in the completed screen to limit the relative move.- ment of the frames in one direction.

3. An adjustable screen comprising a pair of similar frame members consisting of side and end members connected together, said side'members each having a channel integrally formed along the outer edge thereof, slides formed on the extremities of one of' the end members of each frame for engagement in the channels of the other frame, portions of the slides of one frame member being in alinement and engageable with portions of the slides of the other frame member in the completed screen to limit the relative movement of the frames in one direction, and means to limit the relative movement in the opposite direction. l

4. An adjustable screen comprising a pair of similar frame members consisting of side and end members connected together, said side members each having-a channel integral ly formed along the outer edge thereof, with saidchannels extending throughout the length of said side members, slides formed on the extremities of one of the end members of each frame and projecting laterally beyond the outer edge of the end member for engagement in lthe channels of the other frame, portions of the slides of one frame member being arranged to engage with portions of the slides of the other frame'member to limit the relative movement of the frames in one direction." 7

5. An adjustable'screen comprising a pair of similar frame members consisting of side and end members connected together, said side members each having a channel integrally formed along the outer edge thereof, said channels extending throughout the length of said side members, slides formed on the extremities of one of the end members of each frame and projecting laterally beyond the outer edgeof the end member, said slides being spaced from and out of alinement with the adjacent channels in the same frame mem-' ber for engagement in the channels of the other frame when said frame members are placed in superposed'relation.
