JOSEPH M. HOMMEL, OF DETROIT, MICHIGAN.
WINDOW-SCREEN.
SPECIFICATION forming part of Letters Patent No. 394,489, dated December 11, 1888.
Application filed July 23, 1887. Serial No. 245,139. (No model.)
To aZZ whom it may concern.-
Be it known that I, JOSEPH M. HOMMEL, a citizen of the United States, residing at Detroit, in the county of 'ayne and State of Michigan, have invented certain new and useful Improvements in Vindow- Screens, of which the following is a specification.
.My invention relates to improvements in extensible window-screens, and more particularly to that class of screen which has a wooden panel at each end sliding on the main frame, whereby it is adapted to fit window-openings of varying widths.
My invention consists, chiefly, in the combination of the upper bars of the sliding panels with a rib or plate which fits in grooves of said bars and guides them, while also closing the space between their inner ends, substantially as hereinafter set forth and claimed.
Figure 1 is a perspective view of my screen, showing also part-s of the parting-strips of the window-casing. Fig. 2 is a partial elevation of the outer part of the screen. Fig. 3 is a crosssection at .r, Fig. 1.
In the drawings, A is the main frame, in which is secured a wire-cloth screen.
B B are the extensible end panels, tenoned into the top rails, 5 B, and bottom rails, B I3 In the present instance the panel-rails are secured to the main frame by a screw, (and washer,) a, passing through a slot, b, in each rail into the top or bottom rail of the screen-frame, giving each panel a lateral adjustment equal to the length of the slot, as seen in Fig. 2. In the outer end of each panel is a vertical groove, 0, which embraces a pair of staples, d (1, partially driven into the parting-strips E E of the window-casing. The lower staple should be driven about seven inches above the sill, so as to permit the screen to be raised far enough to operate the outside blinds. 'hen the panels are extended to fill the space between the two parting-strips, the staples will keep the screen in place and permit the sash to be raised and lowered in close contact with the rails B and B This would, however, leave a space for insects to enter between the endsof the top rails, B. I therefore slot the inner ends of said rails, as at e, and secure to the top rail of the screen-frame a rib, C, of width equal to the thickness of said rails B, which not only accomplishes the object mentioned, but also guides the panels in their movement and prevents them from twisting and cramping on their screw-studs.
As is frequently the case, the sash is not balanced, and to support it in the proper raised position I secure to the upper rail of the screen-frame a swinging turn-buckle, D, by driving two staples, f f, into said rail, which staples straddle the vertical part of said turn-buckle, which is preferably made by bending a long rivet to the form shown. The head of said rivet enters a groove in the rail, and is thereby prevented from moving up or down. The two staples d being partly driven into the parting-strips to set the screen in place, (the lower sash being raised,) rest it on the sill with the end panels in the plane of the parting-strips, extend the panels laterally against the parting-strips, when the staples (I will be inclosed in the grooves 0, lower the sash until its bottom rail rests on the turn-buckle D, the outer s'urface being then in close contact with the rails 3 of the screen-frame and the stop-rib t.
The sash can be lowered by swinging back the turn-buckle without removing the screen. The screen can be raised on its guide-staples d to open or close the outside blinds. If desired, the screen can be left in place the entire season, in which case a turn on the screwstuds (I will clamp the panels fast.
The described improvements are equally applicable to all screens hzwing laterally-adjustable end panels, regardless of the manner of their connection with the screen-frame proper.
I claim as my invention 1. The main frame A, the extensible end panels, B, and the upper and lower rails, B B attached to said panels, in combination with the flat horizontal plate 0, which fits into grooves in the said upper rails, B, and is of width equal to their thickness, said plate closing the top of the supplemental frame formed by the parts B B B aforesaid and guiding said upper rails, substantially as set forth.
2. The main frame A, the extensible end panels, B, and the upper and lower rails, B B attached to said panels, in combination with the flat horizontal plate 0, which fits into grooves in the top rails, B, and is of width equal to their thickness, said plate guiding said rails besides closing the opening between them, and the turn-buckle D, attached to said plate, for the purpose set forth.
