Application filed January 4, 1923. Serial No. 610,627.

To all whom it may concern:

Be it known that I, DANIEL Hor'r, a citizen of the United States, residing at East Orange, in the county ofEssex and State of New Jersey, have invented certain new and useful Improvements in Weather Stripping; and I do declare the following to be a full,'c1ear, 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.

This inventionrelates to certain new and useful improvements in a railroad car window and it has for its primary object to provide a structure more in the nature of a metallic weather stripping which will maintain the window sash tightly in the window frame against rattling regardless of the surrounding atmospheric conditions.

Heretofore, it has been necessary to loosely fit car windows in their frames to allow for the swelling and shrinking of the woodwork with changes in the weather. Frequently swollen sashes stick and render it almost impossible to raise them to an open position, and when the sashes become dry they shrink to such a degree as to create an annoying rattle as well asproduce a loose fit which readily admits the passage of air and dust about the edges of the sash.

A further object of the invention resides in the provision of a device for holding the sash central and in a perpendicular position in the window frame so as to be practically free from frictional contact at its edges.

The invention will further be found to reside in the salient features of construction hereinafter described and claimed, reference being made to the accompanying drawing, wherein,

Figure 1, is a horizontal transverse section illustrating the improved weather strip ping construction as applied to a car window;

Figure 2, is a perspective view of the sash with portions of the device attached there to; and

Figure 3, is a fragmentary perspective view of the part to be attached to the window frame.

Referring more in detail to the accompanying drawing, the numeral 1 designates the window frame having outer sash stops 2 and inner sash stops 3 cooperating to form vertical guides for the window sash 4. Ad-

jacent to each verticaledge, and secured to the outerface of the windowsash is an angle plate having one flange 5 set inso as to lie flush with the outer surface of the sash, and the other flange 6 extending inwardly over the side edge of said sash and in spaced relation thereto so as to provide a longitudinal pocket 7 The flange 6 mally disposed so as to be covered and con- I cealed by the outer stop 2.

The angle plates extend the full length of the sash frame while the spring plates 8 preferably extend the entire length of the window frame. plates are normally placed under tensionwhen engaging the inner facings of the flanges 6 so that the two spring plates resiliently exert pressure tending to pull the sash in opposite directions, resulting in a centralization of the sash in the window frame. The sash is therefore yieldably held in the frame against lateral shifting movement so as to accommodate for and permit swelling and shrinking of the window under. atmospheric changes. The flange 5 being flush with the outer surface of the sash frame will not obstruct lateral shifting of said sash frame but on the other hand will maintain a tight sliding fit with the outer stop. The free edge of the spring plate 8 flatly engages the flange 6 and thereby closes the joint between the sash and thewindow frame so that should dust sift between the sash and the outer stop it will be arrested by the spring plate8 and the outer cooperating flange 6. Should one spring plate. 8 be weaker than the companion spring plate, the stronger plate will draw the sash in its direction thereby tensioning the weaker spring to a point wherein the two springs will be equalized. Thus the sash is firmly held by the strong springs against rattling and yet permits of an swelling or shrinking of the woodwor without in any way affecting the ease with which the window may be raised or lowered.

In operation the spring 7 In the drawing I have shown but one construction but this may be modified in various ways. Therefore, I do not wish to be limited to the specific construction shown.

What is claimed is 1. A car window comprising a window frame member that consists of a window frame having inner and outer stops, a window sash member having its face edges loosely disposed between the stops in said frame member, each side edge of the window sash member being spaced from the window frame, angle plates secured to one member at the respective sides thereof, each plate having a flat free end portion extending within the respective space between said members and spaced from each of said members, and spring plates secured to the other member at the respective sides thereof, each .of said plates extending freely within the respective space between the said one memher and the fiat free end portion of the adjacent angle plate, and having no contact with the latter except at the extreme end of the spring plate, which extreme end always contacts with said flat portion of the angle plate under spring tension.

2. A car window, comprising a window frame having guideways for a sash, a sash adapted to move therein, the side edges of said sash being spaced from the frame, an angle plate secured to the sash and having a flat free end portion extending into the space between one of said side edges and the frame andfree fromcontact with either,

the flat free end portion constituting a bearing plate, and a spring plate secured to the frame and extending freely within the'space between the sash and the bearing plate, said spring plate being so formed that only its extreme end contacts with the bearing plate and is maintained in contact therewith under spring tension.

In testimony whereof I aflix my signature hereto.
