UNITED STATES JOHN o. WAGNER, or CHICAGO, ILLINOIS.
\ CAR-WINDOW SCREEN.
Application filed February 19, 1923. Serial No. 619,785.
To all whom it may concern. I
Be it known that I, .loIrN VVAoNEn, a citizen of the United States. and a resident of the city of Chicago. in the county of (look and State of Illinois. have invented certain new and useful Improvements in a Car-VVindow Screen; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanyingdrawings, and to the numeralsof reference marked thereon, which form a part of this specification.
This invention relates to window screens especially of that type used on cars. and concerns itself primarily with means for securing the screen against liability of rattling and for .locking the same in an elevated position by a normally concealed member which is adapted to be brought into use when the screen is raised.
This invention comprises the novel mech anism and combinations hereinafter described and morev particularly pointed out and detined in the appended claims.
In the accompanying drawings which illustrate. a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views:
Figure l is an elevatitmal view of the outer side of a car window.
Figure 2 is an enlargedfragmentary interior elevational view with parts broken away showing the screen in elevated position behind the panel.
Figure 3 is an enlarged fragmentary bottom plan view of the screen with the screen guideway shown in section.
Figure 4 is an enlarged broken and transverse section through a Pullman car window construction illustrating certain features of this invention.
Figure 5 is. an enlarged broken section upon the line 5--5 of Figure 4 with parts in elevation.
Figure 6 is an enlarged section upon the line 66 of Figure 5.
' Figure 7 is an enlarged fragmentary elevational view with parts broken away illustrating certain features.
In referring now to the drawings. it will be observed that the screen comprises :1 rectangular frame 1 of well known construction for retaining the foraminous sheet 2.
.the tools. may be passed for operating the screws.
. 0n the side of the. frame 1 through which the screws 3' pass a guideway in the form of a channel-like extension 6 is secured. This extension is formed from a sheet metal a plate which is stamped to provide a channel- ]ikegroove with retnrned'sides which grip the'sides of the frame 1 as shown in Figure 6; the screws 2) also extending through the' web of the channel extension. A pair of leaf springs 7 (Figure 5) are secured at one end to the web of the channel. extension (5 so as to be within the channel thereof directly over the screws 3 which are adapted to contact therewith and press the same outwardly. p
()n the side of the frame 1 opposite the channel extension (5 there is a guidcway in the form of a channel extension '8 (Figure 4-) provided with a concave channel-like groove with returned sides which grip the sides of the frame. The sides of the screen may therefore be said tobe provided with guideways or grooves.
A convex guide strip 9 secured to the side of the window frame fits in the guideway of the extension 8, while an extended guide 10 on the opposite side of the window frame fits in the guideway formed by the extension 6. The guide 10 is formed by stamping a metal plate with a deep channel-like groove forming thereby a forwardly projecting hollow guide tongue; the rear ends of the plate being stamped to provide an open channellike groove for fitting over and securenient to an anchor strip 11 secured to the side of the window frame.
Normally concealed within the hollow tongue '10 is a strut 12 pivoted intermediate its ends to the tongue 10 and swingable beyond the front of theguideavhich is suit ably slotted for this purpose as shown in Figure 7; An opening 12 (Figure 2) in the guide 10 allows the lower end of the strut to be normally swung. The upper end of the strut 12 has its rear corner cut away to 10 by sufiiciently produce a restrictedpro ection 13 adapted to enter an aperture 14 mAjthe bottom of the frame 1 when the screen has been sufliciently elevated and the upper end of the strut has been swung forwardly.
The screen with the lateral guideways 6 and 8 secured thereto may be readily placed in position with relation to the guides 9 and turning the screws 3 inwardly so that the guideway 6 may be positioned over the guide 10 and shifted sufficiently to allow the guideway 8 to clear the projecti0n9. Then by adjusting the screws 3' all play and slack may be taken up as is obvious.
I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted, otherwise than necessitated by the prior art.
I 'claim as my invention:
1. A screen comprising a frame, guide- Ways secured to the lateral sides of the frame, leafsprings secured in one of said guideways, and adjustable screws concealed in said frame extending through the frame and into the last-mentioned guideway and into contact with said springs.
2. The combination with a screen having lateral guideways, of' guides for cooperating with said guideways, one of said guides being hollow, and a strut pivoted in saidhol- 'low' guideway and swingable therebeyond for latching the screen in elevated position. In testimony whereof I have hereunto subscribed my name.
