Application filed February 18, 1915. Serial No. 9,010. i

To all whom it may concern: i

Be it known that I, HARRY H. SGHROYER,

a citizen of the United States, and a resi-- dent of the city 'of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in leather-Strips for Car-VVindows;.and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing's, and to the numerals .of reference marked thereon, which form a part of this specification.-

This invention relates to weather stripping for car windows, and has for its object to provide certain improvements in the construction disclosed in Letters Patent No.

. 1,094,481, granted April 28, 1914, to the Acme Supply Co., as my assignee.

This object I accomplish in the manner and by the means hereinafter described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a fragmentary exterior view of a car illustrating a window equipped with Weatherstripping means embodying the principles of my invention.

Fig. 2 is a fragmentary detail section taken on line 22 of Fig. 1.

Fig. 3 is a fragmentary detail section taken on line 33 of Fig. 1, illustrating the sash in an elevated position.

Fig. 4 is a fragmentary exterior view of the lower corner of the window construction with the sash in the position shown in Fig. 3.

Fig. 5 is an enlarged fragmentary detail sectfion taken through the lower rail of the sas Fig. 6 is a view similar to Fig. 3, illustrating the sash in closed position.

As shown in the drawings:

In the adaptation of my invention herein illustrated, the frame for the sash forms .on the opposite side of said inwardly stamped portion 4, a similar tracking memher 6, is formed. An outer cheek plate 7, of the window post is flanged around and secured to the exterior surface of said tracking member 6, and extends inwardly-across the window frame an amount substantially equal to that of the inner stop 3, thus aflording a Weatherstripping outer side stop 8. The window sash itself consists of side stiles 9, and top and bottom rails, of which the bottom rail is indicated by the reference numeral 10.

The outer surfaces of said stiles 9, of the sash are provided with stepped recesses, as clearly shown in Fig. 2, each to receive the stop or eatherstripping element 8, therein, and plates 11, are secured in flush relation upon the exterior of said stiles 9, and pro ject over said recesses, overlapping the elements 8, and thus sealing the same in the pocket thus formed.

The sill of the window frame is formed of a sheet of metal 12, stamped to the re quired shape, and, as clearly shown in Figs. 3 and 6, the sill inclines downwardly on the exterior of the car. An inner sill 13, preferably of wood, is secured upon said sill member 12, in any suitable manner, and

extends transversely across the window frame between the side members thereof, so that the lower rail 10, of the sash when in a lowered or closed position, as clearly shown in Figs. 1 and 6, abuts against the outer edge of said inner sill member 13, and rests upon the inclined surface of the sill member 12. The under surface of the rail 10-, of the window sash is inclined an amount corresponding to the inclination of that portion of the sill member 12, against which the window sash rests when in closed position, and secured upon said under surface of said rail 10, is a strip of metal 14, folded inwardly at its outer edge into a suitable recess therefor, indicated by the reference numeral. 15, at the outer edge of the rail, and at the inner edge of the rail curved downwardly, as indicated by the reference numeral 13.

A sealing or Weatherstripping element, such as rubber or any other suitable flexible material 17, is secured upon said metal plate 14, by means of a strip 18, which may be attached thereto by screws or other suitable means. Said flexible material 17', as clearly shown in the enlarged view in Fig. 5, is attached along its central portion near the inner edge of the rail member so that the margins of said strip depend downwardly and are normally inclined outwardly, the stiffness of the material itself serving to maintain the outer margin projected outwardly and downwardly, and the curved portion 16, of the metal strip 14, serving to hold the inner margin normally in the position shownin Fig. 5.

When the window sash is drawn upwardly to any of the various positions illustrated in Figs. 1, 3 and 4:, the outer margins of the sealing strip 17 at its ends track behind the fixed stop members 8 on the window frame, thus springing said strip in-' wardly and preventing the same from retaining a set form or losing its resiliency. However when the sash is lowered, the strip will be forced outwardly and downwardly upon the inclined sill member 12, and as the lower ends of said stops 8 are cut away,v

- leaving recesses 19 between the ends of the same and the surface of the sill 12, the ends of the strip 17 will be projected through said recesses 19 and will be pressed down upon said sill 12 by the lower ends of the plates 11 on the sash, as clearly seen in Fig. 6. At the same time the inner margin of said sealing strip 17 is flexed outwardly and compressed etween the strip .18 and the upper surface of the sill 12, as clearly shown in Fig. 6, thus afi'ording another line of seal for the sash when in closed position in the window frame.

I claim as my invention:

In a device of the class described, a window frame, a window sill, a sash 'slidable in said frame, a resilient Weather stripping secured to the underside of the sash and having an outer depending margin, outer side stop members secured to said frame and overlapping said sash and terminating slightly above the window sill to permit the projection therebeneath of the ends of said weather stripping when the sash is lowered to its closed position, and plates on said sash overlapping said stop membersand adapted when said sash is lowered, to press down upon the sill the ends of said weather stripping projecting from beneath said stop memers.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
