J. A. BALDWIN.
EXTENSION SCREEN.
No. 430,559. Patented Junev 17, 1890.
JUDSON A. BALDWIN, OF XVINOOSKI, ASSIGNOR TO THE QUEEN ANNE SCREEN COMPANY, OF BURLINGTON, VERMONT.
EXTENSION-SCREEN.
SPECIFICATION forming part of Letters Patent No. 430,559, dated June 17, 1890. Application filed October 26, 1888- Serial No. 289,285. (No model.)
To all whom it may concern:
Be it known that I, J UDsoN A. BALDWIN, a citizen of the United States, residing at \Vinooski, in the county of Chittenden and State of Vermont, have invented certain new and useful Improvements in Extension-Screens, of which the following is a specification, reference being had therein to the accompanying drawings. i
My invention relates to an improvement in extension windowscreens; and it consists of panels or slides so attached at either end to pieces designed to slide in corresponding grooves in the outside edges of the horizontal bars of the screen-frame that the entire construction may be made of the cheapest material, in the simplest manner, and without affecting the ease and reliability of their lateral adjustment to the varying width of windew-frames.
In the drawings, in which similar letters in dicate like parts, Figure l is a horizontal section of my screen. Fig. 2 is an edge view of the same. Fig. 3 is a perspective of one of the slides. Fig. 4. is a perspective of one corner of the screen. Fig. 5 is a side elevation of the screen complete. Fig. 6 is an end view of Fig. 5.
A is the screen-fra1ne, which is designed to be covered with wire-netting, which-is secured between the front and rear bars B B, which compose the top and bottom bars of the frame, and upon the end bars 0 C of the frame in the usual manner.
D D are end panels, which are intended to extend the width of the frame A at either end bybeing secured at their top and bottom extremities to the sliding pieces 1) b, which are provided with a tongue G on their interior or under edges, so as to readily slide horizontally in corresponding grooves I in the exterior edges of the front bars B of the frame. The pieces Z) I) are of sufficient length to form a bearing to sustain the panels when drawn out their full width. Their outward movement is limited by the strips (1 d, which are attached to the under side of the inner edges of the panels, and between the bars B B of the top and bottom bars coming in contact with similar strips e, secured to the corresponding faces of the end bars 0 C. The closing movement of the panels is similarly limited by the interior extremities of the sliding pieces I) 1) running against the intermediate pieces f f on the top and bottom bars in the path of the bars I) b. As the netting is secured between the front and rear bars B B of the frame A, which is subsequently covered by the pieces which form the adj ustable or sliding portion of .the screen, a finished surface is presented on both sides of the frame when the screen is completed for use. By this simple arrangement of parts the screen can be readily constructed entirely of wood, which is the cheapest material to use, Without being susceptible to the objectionable influences of the weather to which it may be exposed, which in Wooden screens of this character as otherwise made of ten prevents the sliding parts from moving easily or at all on account of the shrinking or swelling of the wood. This desired result, as will be noticed, is accomplished by locating the sliding pieces I) Z) on the outside instead of the inside edges of the bar 13, care being bad to have but a single tenon, and this to be sufficientlj narrower than the groove in which it slides to allow for extreme enlargement by dampness. The panels being then secured to these pieces their full width at the extremities of the grain of the wood, are never affected by the temperature, nor do they even curl, so that they always slide easily. At the same time the attachment of the strip d, which forms the stop to their outward movement to nearly the entire length of the panel, serves to give additional stiffness to the panel, thus materially preventing any tendency of the panels to side warping.
The tonguing and grooving of the sliding parts are quickly made by machinery, while the quantity of material required is as little as is possible to have.
' The several parts are readily put together, and the screen when completed perfectly meets the end desired in the simplest, cheapest, and reliable manner possible.
I claim The combination of a screen having top and bottom bars which are composed of front and rear bars and end pieces, the stops sepieces, all combined to operate substantially ro cured to the end pieces, the front bars proas shown and described. I Vided with longitudinal grooves, the panels In testimony whereof Ido aifix my signature provided with the tongued sliding pieces at in presence of two witnesses.
each end which slide in the rooves made in the front bars, the strips secu red to the inner JUDSON BALDYIN edges of the panels, and the stop-strips se- Witnesses: cured to the top and bottom bars at or near CHARLES E. ALLEN,
their centers and in the path of the sliding ELMER E. DAVIS.
