SOlaims.

This invention relates to window sash constructions for vehicles, such as railway cars, and has for its object a mounting for the sash by which the sash is frictionally moimted in the window frame and capable of edgewise shifting within limits to relieve the glass pane of the force of jerks and shocks and strains occurring when the vehicle or car is more or less suddenly stopped or started.

19 It further has for its object a window construction for vehicles, as railway cars, which are streamlined and the window sashes are so mounted that their outer faces are nearly flush with the outer surface of the car body.

[I It further has for its object a simple and compact means for frictionally holding the sash in the window frame in such a manner that it is capable of edgewise shifting movement within limits.

9 Other objects will appear throughout the speciiication.

The invention consists in the novel features and in the combinations and constructionsv hereinafter set forth and claimed.

a In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

a Figure 1 is a fragmentary elevation of a windowv structure embodyi s this invention.

Figure 2 is a fragmentary sectional view on line 2-2, Figure 1.

Figure 3 is a sectional view on line 3-4. Figure 1.

Figure 4 is a fragmentary detail view of a single sash construction embodying this invention.

In streamline trains, which are air conditioned, the window sashes are stationary. Heretofore,

' it hasbeencustomarytoattachthesashinthe window opening or window frame with screws from the outside. These screws present a more or less imsatisfactory appearance and require numerous holes in the frame and in the sash.

One of the principal features of this invention is a compact means for holding the sash, either single or double, in position, which holding means is concealed and not exposed on the outside of the car and located for'the most part beyond the edges of the sash. Further where the sashes are attached rigidly to the car body posts or frames any strains set up by sudden impact (such as contact with bumping posts or in coupling the cars together) are transmitted direct to the sashes with consequent damage to glass and sash frames, hence it is desirable to have the sash structure held yielding in the opening.

i designates generally the frame which may be an integral part of the 'car body structure or a separate frame, it beingusually an integral 5 part of the car structure around or confining the window opening. The frame or the car body is usually formed of sheet metal and also formed so as to provide a channel C aroimd the window opening with the open side of the channel presentedtoward the window opening.- It is in this channel that the sash frame or frames extend.

2 designates the outer sheet metal plate of the window frame;' 3 a second plate annular in cross section with a flange 4 lying against the inner face of the plate 2 and with a flange i spaced apart from theplate 2 and forming a surface for the interior trim of the car. These plates are usually an integral part of the car bodystructure. I m

6 is a sill mounted on the intermediate part of the plate 3 and forming the side of the channel opposed to the outer side formed by the plate 2 and flange l.

In Figures 1, 2 and 3, a double sash is'shown. u The double sash construction has all features of the single sash construction shown in Figure 4 particularly, in so far as the clamping strip for holding one of the double sashes or the single sash in the channel of the frame is concerned.

One of the principal features of the invention is the means by which the glass pane is yieldingly mounted and also frictionally mounted in the window frame, so as to shift within limits in an edgewise direction. Each sash, as here shown, includes a glass pane and the mounting.

therefor, which is a sash frame slidably or frictionaily mounted in the window opening or window frame with a portion or flange on one side thereof frictionally engaging one side wall of a channel formed in the frame, where it is frictionally held by clamping meansfi The channel in the frame extends entlrelyaround the sash and is of such depth that the sash frame is capable of shifting edge wise in any directionunder the influence of Jerks or shocks, so-that the glass pane is relieved to a large extent of the force of the shocks and jerks.

In Figures 1, 2 and 3, the sash construction includes outer and inner sashes designated generally ii and i2, each including a metal sash frame usually of extruded metal and designated respectively l3 and I. The extruded frame members may be of any suitable cross section, and, as here shown, the outer side of the outer sash frame it s presses against the plates 2 and I of the window frame, the sash frame being formed with a circumferential flange II which thrusts against the outer wall of the channel C. The flange I of the window frame member 8 terminates at'its edge short of the inner edge of the plate 2 leaving a rabbet, and the sash frame I! is formed with a log it seated in the rabbet. The glass pane of the sashsea'ts in a U-shaped sealing strip II of yielding material, as rubber, located in a channel in the sash frame it, the inner side of the channel being removable and being in the form of a glazing strip II, one margin of which seats in a groove it formed in thesash frame It.

The means for frictionally holding the sash frame it in position is one or more clamping strips 2i extending lengthwise of the rails and stiles of the sash and located in the channel C, this strip being fulcrumed at one edge at 22 on the bottom of the channel C, that is, on the intermediate part of the plate 2, and having its opposite margin or flange 2i pressing toward the inner face of the sash frame II, this strip being clamped in position by screws 28 extending through the intermediate part of the strip between the fulcrumed edge 22 and the flange 24 and threading into the bottom of the channel; Preferably,as here shown, this strip is Z shaped in general form in cross section with the edge of one arm of the 2 formation fulcrumingat 22 and the other arm, as 2|, pressingflatwise againstthe sash frame it, and the screws 2| extend through the intermediate part of. the 2 formation.

Theinner sash II is of similar construction but is provided with a marginal flange 28 corresponding to the flange ll coacting with or engaging the edge of the sill 8 provided at one side of the channel C and with the glazing strip 21 corresponding to the glazing strip I. located on the side of the sash frame I toward the sash frame it. 'The flange 24 of the securing strip therefore is interposed between the sash frames and preferably a strip 20 of compressible and absorbent material is folded over the flange in order to be interposed between the sashes. so that the fold is exposedxin the space between the sashes. This .serves to absorb moisture from between the sashes to prevent clouding and frosting, when other dehydration means is not employed.

The inner sash, isflrmiysecuredin theohannel Cby being clamped to the outer sash by means of screws ll extending through the corner port ions of the sash frames, the screws extending through an opening in the inner sash and threading into the outer sash, as seen in Figure 3. In order to permit the ready removal of the inner sash. these screws are studs, and the opening 23 in the inner sash frame i4 is large enough to permittheheadofthestud topasstherethrough. A locking means in the form of a pivoted latch 8| isprovided movable into a position between the head of the stud and the inner sash frame it.

In Figure 4 is illustrated a single saslfconstruc tion, wherein the clamping strip 4i corresponding to thestrip 2|, although 2 shaped in general form is of slightly different contour from that shown 'inl'igurelinthattheintermediatepartofthe 2 formation is considerably wider with respect to the flange 42, corresponding to the flange 2. Also, this strip extends into a recess in the sill, andthesillmustberemovedinordertogiveaccess to the clamping screws ll, corresponding to the screws 2|.

Inthe form shown in Figure 4. the strip,-in-

- of the channel in the window frame and between the base of the flange which presses against the outer side of the channel C and the continuous edge of the wall of the car body forming the window opening, those clearances permitting the sash to shift edgewise when frictionally clamped in position to relieve the sash of the glass pane of sudden shocks tending to break the glass pane.

In either embodiment of the invention, the sash frame is held in position by a strip fulcrumed at one edge having its margin remote from the fulcrum pressing against the sash and a is held in position or moved about .its fulcrum to clamp it against the sash frame by a screw passing through the intermediate part of the strip and threading into the window frame. Also, this clamping strip in either embodiment of the invention is located or concealed in a channel located at the edges of the sash frame.

What I claim is:

1. In combination with a window frame formed with a channel, of a window sash mounted in the channel with one side face against one side ofthe channel, and means located in the channel coacting and pressing against the other side face for clamping the sash in the frame, said the sash, and a screw extending through the strip against its fulcrumed edge and said margin and threading into the bottom of the channel.

2. The combination with a window frame, of a window structure comprising a double sash, one sash being mounted with one side face against the frame, and means coacting and pressing against the other side face for clamping the same in the frame. said means comprising a strip substantially z-shaped in cross vsection with one of the arms of the Z pressing against the other side face of the sash and the edge of the other armof the Z fulcruming on a portion of the frame, and clamping means extending through the intermediate part of the Z strip and coacting. with the adjacent portion ,of the frame and tending to tilt the strip about whereby said arm of the 2 strip is interposed between the sashes, and means for securing the second sash in the frame.

3. The combination with a window frame, of a window structure comprising a double sash, one sash being mounted with one side face against the frame, and means coacting and pressing against the other side face for clamping the same in the frame, said means comprising a strip substantially Z shaped in cross section with one of the arms of the Z pressing against the other side face of the sash and the edgeoftheotherarmofthezfulcrumingon 40 margin remote from the'fulcrum pressing against v a portion of the frame, and clamping means extending through the intermediate part of the Z strip and coacting with the adjacent portion of the frame and tending to tilt the strip about its fulcrumed edge and clamp the strip against the sash, the second sash being mounted in the first sash in position, whereby said arm of the Z strip is interposed between the sashes, and means for securing the second sash to the first sash and clamping the same against the interposed strip.

4. The combination with a window frame formed with a channel facing the window opening, of a window sash extending in the channel and mounted with one side face against one side wall of the channel, means coacting with and pressing against the other side face of the sash for clamping the sash in the frame, said means including a strip located in the channel and extending lengthwise along the stiles and rails of the sash, and means for securing the strip in the channel, a second sash mounted in the frame with one side face thrusting against the said strip, and means connecting the sashes for clamping the second sash toward the first sash and against the strip, and a sealing strip of compressible, moisture absorbent material interposed between the sashes and the strip and having a portion exposed in the space between the sashes.

ment with the window frame in a direction cross-- wise of the edgewise movement, said means pressing on one side of the sash frame to press the other side into frictional engagement with one side of the channel of the window frame, including a strip located in the channel and extending lengthwise along the stiles and rails of the sash, means for securing the strip in the channel, a second sash mounted in the frame with one side face thrusting against said strip, and means connecting the sashes for clamping the second sash toward the first sash against the strip, all whereby both sashes are capable of sliding edgewise, as a unit, under shocks and are braked in their sliding movement by the frictional engagement of the first sash with one wall of the channel and frictional engagement of the other sash with said strip by reason of it being clamped to the first sash.
