' I Claims. (01. 9893) This invention relates to an improvement in screens and particularly to one for use between a partially upraised sash and frame therefor.

In its preferred embodiment this'invention con- 5 templates the provision of a window screen having automatic extendable means by which to hold it in place and a hinged or verticaly removable wind deflector which may be made to lie fiat in the same plane with the screen when not in use. It is well known that prior to this invention screens of this general class have been employed but it is believed that none of the structures now in use compare with applicants device in sturdiness, ease of handling and compactness in storing. Car screens, to which this invention is primarily directed, are undoubtedly subjected to more mishandling than almost any other type of window screen. The reason for this is obvious, as for instance, trains traveling across the continent daily pass into and out of cold and temperate parts of the country and as a result the window screens are removed one day, inserted the next, etc. Furthermore, when trains are being made up, allof the equipment including the window screens is cleaned and it is therefore essential.

that screens of this type be readily insertable and removable in order to facilitate this operation and incidentally save considerable wear thereon by preventing undue forcing into or out of place. A further consideration in producing window screens lies in the fact that each car must carry compact equipment for every purpose.- Since storage space is greatly taxed, to include window screens, which are not adaptable to compact storing, is out of the question. It is essential each window screen be provided adjacent one end with some form of wind deflector which, when the screen is not in use, may either be removed or made to lie flat in the same plane with the screen to facilitate compact storage of a quantity of said screens.

The principal object of this invention is to provide a screen which may be easily and with little effort inserted into or removed from a car window frame.

Another object of this invention is to provide a device of this class, the construction of which is so arranged, as to permit compact storing of a number thereof when not in use.

A further object of this invention is to providev a device of this class, the structure of which is of ample strength to withstand the abuse of con- M stant handling to which screens of this type are 7 necessarily subjected.

. Other and further objects of this invention will appear from a consideration of the following specification when taken in conjunction with the accompanying drawing; and in which" Fig. 1 is a perspective view of a car screen and frame showing one modification of this invention in position of use;

Fig. 2 is agreatly enlarged vertical sectional view taken on the line 2-2 of Fig. 1, showing an adjustable shoe which facilitates the insertion or removal of the screen from a window frame;

Fig. 3 is a fragmentary view similar to Fig. 2 showing the adjustable shoe in collapsed position;

Fig. 4 is a horizontal sectional View of the adjustable end of the device being taken substantially on the line 4-4 of Fig. 1;

Fig. 5 is an enlarged fragmentary verticalsectional view taken on line 55 of Figure .1 showing the manner of mounting a weather strip between the sash and the screen and also the mannerof securing the wire screening upon the frame;

Fig. "6 is a" fragmentary horizontal sectional view showing one method of removably mounting the wind deflectorplate upon oneend of 'the screen; and p I i Fig. 7 discloses a vertical sectional view of a further modified type of wind deflector. I

Referring to the drawing this invention is disclosed as applied to a screen 10 intended for use within a window frame 12. The frame 12 is provided with the usual guide channels 14 in which the sash 15 reciprocates. The screen 10 comprises a hollow frame 1.? having wall elements 18, 19, 20 and-21. Each wall of the frame is provided with a channular recess 22 adjacent the innermost edge'thereof. The recess 22 is formed by the flanges 23,24 and 25. The flange 23 is flared to cause the recess 22 to be wider at its base than at the top thereof, the purpose of whichwill later be described. The wall elements are each providedwith inwardly extending flanges 27 which closely overlap the outer edge of each of the flanges 25. 1

Attention is here directed to the fact that the frame 17 is comprised of four elements,namely, two vertical and two horizontal, which are welded or otherwisesuitably joined together to form the complete frame. Each of the elements comprising the frame are provided with recesses 22 of identical configuration which constitute a part of the securing means for the screening covering the area within said frame. The horizontal elements 18 and 20, however, since they must be capable of sealingly engaging the window frame l2 and the sash 15, are provided with movement of the weather strip with relation to .of the frame.

' from one end of each element. In as much as the portion 31 of the weather strip snugly en gages the walls of the recess 33, no additional retaining means is supplied bywhich to prevent the frame.

Mounted at one end of the screen 10, and supported upon one of the vertical elements of the frame 17, is a movable channel shaped shoe The shoe 35 (see Fig. 4) consists of side Walls 36, 3'7 and base wall 38. The walls 36 and 37v enclose and .teiescopically engage'the wall'21 The wall 37, however, is provided with inwardly extending flanges 39. The purpose, ofthe flanges 39 is to prevent complete disengagement of the shoe 35 from the vertical element 21 of the frame. Referring now to Figures 2 and 3, it will be noted that the outer wall 40 of the element 21 is provided with an opening 42 therethrough. One or more springs 43 lie 7 withinthe shoe 35, the loop 44 of which extends the frame.

against the inner face of the base wall .38 thus I vertent removal ;-of

through the opening 42 into the element 21 of The ends 460i the spring 43 bear causing the shoe 35 to be normally extended, the distance being determined by the point of contactoi the flanges39 of said shoe with the flange 27 of the element 21.

When it is desired to mount the screen, the shoe 35 is compressed against the tensionof the spring 43 and again released when the screen is in proper position. It iscontemplated that the shoe '35 will rest withinone of the guide channels 14 and that a sufficient expansion as between frame andshoe will occur to prevent any inadthe screen 3 when once The end of the screen 10,. formed by the wall 19; as may be seen in Figures 1 and 7, is provided with.a.wind deflector 50, which may be of any desired angular configuration, however, preferably as shown in the drawing. .The deflector 50, adjacent. its pivoted edge, is twice bent'to create flanges 51 and 52. Securedin any suitable manner as by welding, to the flange 52 is one element of a hinge 54. The other element'of the hinge is secured, as by welding, to the outer face of mounted,

the wall 19. As shown in the drawing, the de tain circumstancesit is preferred that the de-' flector 50 be permanently attached to the screen I 10, thereare occasions when'a car screen having a removable deflector, as .shown in Figure 6 of the drawing, is preferred. In this instance the deflector 55 is terminated at one end by flanges 56, 5'1 1 and 58'forming a'recess into which the end wall 19 of the screen 10 is fitted. When the-deflector 55 is in position upon the screen 10, said screen may then be inserted in the window frame12 and the deflector will be rigidly held in place until such time as the screen is again removed; With this method of mounting the deflector upon the screen,,it is'possible, when removing the screens for storing, to .place one 'screendirectIy upon the other in a slightly more in each of the walls 18, 19, 20 and 21.

compact manner than is possible with the hinged deflector, above described.

The space within the frame 17 is covered with wire or cloth screening 60. The edges of the screening are pressed into the recesses 22 formed the screen is thus placed upon the frame, U

shaped retaining members 62 are pressed into therecesses 22. The members 62 engage the screening 60 adjacent the flanges 24 and 27. Since the walls of the recess 22 define an opening slightly less than the width of the member 62, it isnecessary to force said member into said recess and by so doing the screening 60 is securelyheld in place upon the frame. The flange 23, when the member 62 is in place within the recess 22, creates a pocket in which the edge of the screening 60 is located. Shouldthe screening 60 ,at any time become damaged, it is a simple matter to remove the members 62 from each of the elements of the frame, mount a new piece of screening and reposition said members.

The above described invention is assembled and mounted in the following manner. The frame elements or walls l8, 19, 20 and 21 are joined together in any suitable manner as by welding, each elementbeing assembled with the recess 22 opening upon the same side of the frame as the recesses of the adjacent elements. One or more springs 43 are mounted upon the element 21 by passing the loop or loops 44 thereof through the opening 42 in the outer wall 40 of said element. Prior to assembling the channel shaped shoe 35 upon the frame 17,- the flanges 39 are only slightly bent from the plane of the wall 37. The shoe 35 is brought into engagement with the ends 46 of the springs and said springs are compressed as the walls 36 and 37 are spread to facilitate passage of the flanges 39 past the element 21. The flanges '39 are bent at right angles to the wall 37 thus preventing removal of said shoe from the frame through the expanding action of springs 43. The deflector 50 and hinge 54 may be secured to the element 19 of the frame at any time during assembly. Screening 60 is now placed upon the frame 17 with the edges thereof covering outer edge of each member 62 is flush with the inner wall of the frame elements, the screening is engaged in two places, namely, between the opened edge of the members 62 and the flange 24, and between the side of each member and released, the expansionof the springs 43 causes it to bear firmly against the inner face of each guide channel. It is to be noted that when the screen is mounted within a windowsframe, the shoe 35 constitutes a pressure member at oneend and the flange 52 of the deflector the pressure member at the other end. It is pointed out that pressure upon the flange 52 causes the deflector,

alongthe flange 5lthereof, to abut the outer face of the element 19 of the frame. It is further .When a pointed out that the screen having similar top and bottom elements may be reversed end for end to position the deflector 50 adjacent either side of the window frame. The deflector 55, prior to mounting the screen 10 within the frame, is slidably engaged with the element 19 of said screen. In this instance the expansion of the springs 43 causes the flange 57 of the deflector 55 to bear against the inner wall of theguide channel 14 thus preventing all movement of said screen, relative to said frame.

It is pointed out that although this invention is shown and described as particularly adapted for car windows, it is contemplated to provide screens of this type for any window where it is desired to screen the opening and deflect a direct blast of air from passage therethrough.

While only one modification of this invention has been shown and described, applicant does not intend to be limited thereto inasmuch as other modifications and adaptations may be made without departing from the spirit and scope of this invention as set forth in the hereunto annexed claims.

Having thus set forth my invention what I claim'is new and for which I desire protection by Letters Patent is:

1. A removable screen for window mounting comprising a frame, pressure means engaging one end of said frame, and a wind deflector joined to the other end of said frame, said pressure means being adopted to retain said screen and said deflector in engagement with each other and with said window mounting.

2. A removable window screen comprising a frame, wind deflecting means joined to one end of said frame, a spring pressure shoe telescopically engaging the other end of said frame, said shoe being adapted to retain said screen and said deflecting means in engagement with each other Whenin position of use.
