Figure 3 isa transverse sectional view through the stile of the sash showingthe weather strip in normal position before being 'compressed in the channel of the sash guide.

In the illustrated embodiment of my invention,

the sash guide or frame is formed with the channel and the sash on the edge of its stile formed with the rib extending into the channel, which rib is embraced by the weather strip. I designates the stile of the sash and 2 the up'- right or body of the sash guide at eachV side of the sash, the sash guide being in the form of a channel, one side 3 of which is removable and f constitutes a window stop.

suitable manner. The bottom 5 of the channel is resiliently pressed outwardly as by suitable springs, es 6, to have a follow-up movement,` and. a self-adjusting movement to conform `ioinise alinements out of the vertical oi.' the post' of the car structure. The construction of the sash guide The guide.` 2 is secured to the post structure 4 o! the car body in any Q removable stop portion per se forms no part of the invention. The window stop 3 is also in the form of a channel and provided with a rack 1 in the channel thereof for coacting with'the pawl 8 oa sash holder 9 mounted on the bottom rail `Ia of the sash on each end of the bottom rail. the pawl being operated by a suitable lever l0. The window stop is detachably secured to the body of the sash guide body in any suitable manner, as by projections H extending through slots in the opposite portion of the main body o! the sash guide and interlocked therewith by verticalV Y opposing surface of the sash guide 2, and then upon a vertical lmovement of the stop 3 interlock or come into hooking engagement with the lower end walls of the slots. This feature forms no part of the invention and is similar to that shown in Axe Patents Nos. 2,329,238 issued September 14, 1943 and 2,090,321 issuedAugust 1'1,` 1937.

The stile l of the sash is formed with a rib i! extending along the edge thereof for entering the channel of the sash guide 2 or between the window stop 3 and the opposing flange or wall of the body of the sash guide 2. I3 designates a weather strip o! resilient iibrous material, as a braided or woven somewhat stiff but iiexible material, capable of withstanding wear, U- shaped in general form and embracing the rib, it being anchored'at itsjedges to the stile l along the base of the rib and having its side and intermediate portions Il, l5 tensioned to normally bulge away from the sides oi the rib :and press against the opposing walls of the channel I, that is. against the stop 3, and the flange opposed thereto and away from the lengthwise edge of the rib to press against the bottom of thek channel. When so arranged in the channel, the weather strip will approach a position similar to lthat shown in Figure 2 Due to the inherent tension to bulge therein.V it willpress against the side walls and the bottom of the channel and thus form `a weather-tight and anti-rattling joint. As will be understood, the spring-pressed bottom oi' the channel compensates for misalinements out oi the vertical and of the sash guide Vmember 2 dueto the posts l on opposite edges f of the sash not being parallel.

The edges oi' the weather strip Il are here shown as anchored to the stile I by having its opposing margins seated in grooves at IC in the base of the rib il. the

3. side walls of the groove being distorted inwardly. atter the margins have been inserted in the groove.

The sash and the sash guide orI the body thereot as well as the window stop are here shown as formed by extruding process. although they may be formed in any other well known manner.

By reason of this resilient weather strip located to bulge as set forth and to compress when in a channel, a sash may be made weather tight and anti-rattling in a. simple .and economical manner.

What I claim is:

A window construction comprising a sash guide formed with a channelhaving a movable resiliently pressed bottom,.and a sash having a rib extending into the channel. the bottom oi the channel having avfollow-up movement toward the end edge oi' the rib, and a weather strip U- shaped in general form and embracing the rib, the strip being anchored to the sash at the base Number Name Date 425,985 Connor Apr. 22, 1890 1,725,365 Mohun et al Aug. 20. 1929 20 2,032,794 Conway Mar. 3, 1936 2.358.427 Pressnall Aug. 22, 1944 of the rib having its side and intermediate porthe sides and end edge of the rib to coact with the sides and bottom of the channel, whereby the pressure ofthe bottom of the channel against the intermediate portion of the weather strip tends to bulge the sides and the compression o! the sides o! the strip between the walls 'of the channel tends to bulge the intermediate portion of the strip against the bottom oi the channel.
