CHARLES LEWIS VAGANDT, OF BALTIMORE, MARYLAND.

POCKET WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No 498,868, dated .T une 6, 1893.

` Application led September 13, 1892. Serial No. 445,786. (No model.)

To a/ZZ whom t may concern:

Be it known that I, CHARLES LEWIS WA- GANDT, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Pocket Window-Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a very light and portable screen adapted to be carried bythe traveler in his pocket or satchel and to be applied at will to any ordinary window for protection against dust, cinders, or insects.

I have designed my screen especially for car windows, and by its use the traveler may enjoyl the refreshing breeze ordinarily produced by the motion of the railway train Withont being subjected to the usual accompanying annoyance of dust and cinders and without being obliged to carry with him a large or cumbersome article.

lVith these ends in view my invention consists in the parts land combinations thereof hereinafter more particularly set forth and claimed.

In order to make the improvement more clearly understood I have shown in the accompanying drawings means for carrying the same into practical effect, without however limiting the invention in its useful applications to the particular construction which, for the sake of illustration, I have delineated.

In said drawings-Figure l is aview of the screen folded and ready for transportation in the pocket or valise. Fig. 2 is a view of the same partly unfolded. Fig. 3 is a View of the screen still farther unfolded. Fig. 4 shows the screen extended and made of a length suitable for the width of the window to which it is to be applied. Fig. 5 shows the device entirely unfolded and applied to the window in the usual manner. Fig. 6 is a sectional View on line VI-VI, Fig. 5. Fig.'7 isa similar view on a larger scale of the top pieces. Fig. S is a similar view of a piece of the screen frame when made of wood.

Referring to the drawings-l and 2 indicate the two top pieces of the screen frame, and 3 and 4 the bottom pieces of similar shape and construction. I may here state that the niateral of the frame may be of wood or of sheet metal. In the drawingsit is shown as formed of tin. The said top and bottom pieces are provided with inwardly extending ears 5 by which they are pivoted together on axes transverse to the plane of the screen, the pivot of the top pieces being shown at 6 and that of the bottom pieces at 7.

p S indicates the side or vertical bars of the frame, each formed of two sections 9, 9 pivoted together at l0 on axes which are parallel with the plane of the screen and (when the screen is in position for use) are horizontal. In other words the pivots l0 are parallel with the top and bottom pieces of the screen when unfolded. The vside sections are pivoted upon the ends of the top and bottom pieces by pins or hinges Il which are at right angles to the pivots l0 and parallel with the pivots 6 and 7.

On the pivots I0 the frame may be folded on a horizontal middle line so as to bring the side sections face to face and the bottom pieces against the top pieces; on the pivots ll the doubled frame may be folded edgewise to bring the inner edges of the side sections against the inner edges of the top and bottom sections; and on the pivots G and 7 the quadruple folded frame may be still farther folded to bring the outer edges of the side sections against each other.

At one or both sides of the screen I provide an extension so that the screen may be made of various widths to it different windows. This I effect by making the top and bottom pieces 2 and fi in two parts the outer (toward the edge of the screen) parts 11a having a sliding movement upon the inner (toward the middle of the screen) parts 12. In the construction illustrated the parts 12 are hollow in the form of sheaths and the parts l1 telescope entirely within them. ticulated material is attached to the frame in any suitable manner. It is made in two

separate parts

13, 14 the former constituting the main portion of the screen and the latter being carried by the sliding extension. These The re- 95 two parts are made to overlap each other a sufficient distance when the screen is fully extended, and by placing the outermost part toward the forward end of the train the breeze will simply tend to keep the two parts closely together and dust and cinders will be perfectly excluded.

For the reticulated material a very fine and flexible fabric is employed. I prefer a rather heavy quality of veiling.

In the construction shown the frame pieces are provided with bends 15 in which I crimp and clamp at the time they are formed the edge of a strong cotton or other fabric 16 which extends all around the interior edge of the frame. This fabric is made in a narrow strip or strips, to which the reticulated material is sewed to complete the screen. If the frame is of Wood the strip 16 may be secured in a groove by a wedge-strip 1'7, as seen in Fig. 8.

The screen is ordinarily kept in the form shown in Fig. 1. Vhen it is desired to use it the partly surrounding fabric is unwrapped and the frame unfolded into the position shown in Fig. 2, and then into that indicated in Fig. 3. While in this position the extension parts of both the top and bottom of the frame are slid out together so as to nearly iill the window to which the device is to be applied (Fig. 4), and then the lower half of the screen is folded down as seen in Fig. 5. The device is then placed in the window frame between the strips forming the groove in which the window runs and the extension pieces still farther slid out until both sides of the screen frame are confined in the said grooves. The window sash 2O is then let down on top of the device. The joints at 6 and 7 are formed with abutting shoulders 18 which prevent the top and bottom parts of the frame from turning inward toward the center of the screen from gravity or from the pull of the fabric, and the window sash strips, shown at 19 in Fig. 6, so engage the side pieces as to prevent the frame from buckling on the joints at 10. The frame is therefore perfectly rigid while in use. The reverse of the unfolding process above described enables the screen to be returned to the pocket. 5

1. The herein described folding pocket window screen, having a reticulated material adapted to be Wrapped up without injury, and

a frame composed of top, bottom and side 51 pieces hinged to each other, each of said side pieces being composed of sections hinged together upon pivots the axes of which are transverse to the axes of the pivots by which the side pieces are jointed to the top and bot- 6 tom pieces, substantially as set forth.

2. The combination with the main frame portion composed of sections hinged together at the corners and intermediately between the corners and adapted to be folded, of an exten- 6 sion frame portion Acomposed of correspondingly hinged sections jointed at the corners and intermedately between the corners and having a sliding engagement with said main portion, the Whole constituting when provided 7.

the plane of the screen and hinged to said top 8 and bottom pieces, substantially as set forth.

4. In a screen the frame composed of the top and bottom pieces having sections hinged together by pivots 6, 7 and the side pieces also composed of sections hinged together by piv- 81 ots 10 and at one side of the screen hinged to the top and bottom pieces by pivots 11, and at the other side of the frame having both a pivotal and a sliding connection with the top and bottom pieces, substantially as set forth. 9

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