7 Claims.

This invention relates to windows, and it has reference more particularly to windows for air conditioned railway cars of the type wherein the sashes are sealed and secured against being moved.

Our invention is concerned with structural improvements in windows of the kind referred to, its chief aims being to facilitate easy and rapid installation of the window frames; and the application to the window frames of the sashes in such a way that, notwithstanding their being secured in place with normal maintenance of a weathertight seal all around, their removal can be quickly effected from within the car to enable ready replacement of broken glass, or, in the event of emergencies, to enable the escape of the passengers if the exits at the car ends should happen to be obstructed.

One way in which the foregoing, together with other objects and advantages, may be attained in practice will appear from the following detailed description of the attached drawings, wherein Figs. 1 and 2 are fragmentary views respectively showing the exterior and interior elevations of a single sash car window conveniently embodying our invention.

Fig. 3 is a vertical section of the window taken as indicated by the angled arrows I1IIII in Figs. 1 and. 2.

Fig. 4 is a horizontal section taken as indicated by the angled arrows IV-IV in Fig. 2.

Fig. 5 is a fragmentary detail sectional View on a larger scale looking as indicated by the angled arrows V-V in Figs. 2 and 3 and showing one of a pair of wedge pivot suspension devices or hinges, whereby, in accordance with our invention, the sash is removably connected to the window frame at the top.

Figs. 6 and 7 are views like 3 and 4 showing a double sash window embodying our invention; and

Fig. 8 is a fragmentary view in elevation showing the provisions made for precluding sweating of the glass in the interval between the two sashes of the double window illustrated in Figs. 6 and 7.

Referring first more especially to Figs. 1-5 of these illustrations, the single sash type of our improved window includes an integrally formed square frame F with rounded corners, whereof the top, bottom and side rails I0, ll, 42 and I3 are all of right angle cross section with their face flanges perimetrically shouldered as at [5 to fit snugly into an opening in the outer wall the frame rails Ill-13 are each recessed longitudinally as at I! at their innersides with resultant formation of a continuous groove for lodgment of a compressible weathering gasket l8 which may be of rubber or the like. The frame F is secured in place from the inside of the car by headed screws IQ of which the shanks pass through suitably allocated holes in the face flanges of the rails I0l3 and threadedly engage into the outer Wall sheet [6 of the car body.

The sash S of the window has an integrally formed square main frame section with top, bottom and side rails 20, 2|, 22 and 23, and a detachable supplemental frame section 24, which jointly provide an internal perimetric groove 25 or recess for retainment of a shatter proof glass pane 26, with interposition of compressible channeled weathering 21. The supplemental section 24 of the sash is held assembled with the main section by screws 28; and a gasket 29 of felt is interposed between them to permit compressing of the channelled weathering 2'! as said screws are drawn up. Separately secured to the side rails 22, 23 of the main section of the sash are comparatively deep jamb members 30 and 3| of angular cross section with longitudinal grooves 32 and 33 which serve as vertical guideways for the slide shoes 34, 35 at opposite ends of the bottom cross rod 35 of a curtain 31, see Fig. 4. As shown in Fig. 3 the roll 38 for the curtain 37 is supported by end bearing brackets whereof one is shown at 39, secured to a longitudinal angle bar 40 of the car framework above the window openings against which bar the outer sheet 16 abuts at the top. To the bottom rail 2| of the sash frame is secured, by screws 4|, a sill bar 42 which reaches inwardly of the window opening, said sill bar being recessed at 43 for reception of a non-metallic sill piece 44, and having its inner end directed downwardly as at 45 to overlap the inner sheet 46 of the car wall. As further shown in Fig. 3, the sill piece 44 is secured by screws 41 which pass upwardly thereinto through holes in the sill bar 43; and from Fig. 4 it will be observed that said sill piece is extended at its ends beyond the side jamb sheets 48, 49 of the window opening as at 55, 5| and meets, in flush relation, with chair rail sections 52 intermediate adjacent window openings.

In accordance with our invention, the sash is detachably connected to the window frame by a pair of horizontal pivot or hinge elements 55, each consisting of two complemental components 56, 51 of which the first is secured by screw bolts sheet I6 of the car body. The face flanges of 55 58 to the horizontal flange of the top rail In of Figs. 3 and 5, the component 56 of each hinge 55 is provided with laterally spaced open hook projections 60 which extend inwardly beyond the frame rail l0, and in which are received-- the ends of a pintle 6| centrally secured in a horizontal boss 62 at the top of th component 51. It is moreover to be noted from Fig. 3, that the front walls of the notches in the hook projections 60 of the hinge components 56 are inclined somewhat to the vertical as at 63 for wedge action with the pintles 6!, whereby, under the influence of its own weight, the suspended sash S is urged outwardly at the top toward the window frame. As a consequence of this, the outer face of the top rail portion of the sash S is automatically forced into pressure contact with the upper cross segment of the rubber gasket l8. The sash S is normally held fixed in position by three cap bolts of which two are shownat 6 5, in Fig. 2, the shanks of said bolts 65 passing through openings fiiin, the pendant flange portion 45 of t e Sillbar 42 (Fig. 3) and threadedly, engaging into the downwardly extended portion 61 of an inverted pressed steel channel member, 68 which forms the bottom of the window opening in the car wall. When the sash S is in position in the window, the upper ends of thegjambmembers 30 and 31 are concealed behind a finishing or moldins str p sho na 9 n s.

In thisconnection it is pointed outthat by virtue of being stiffened by the attached jamb and sill bars t0, 3] and 42, .thesash S is immune against warping or bendin wso that the weathering gasket 1 8 will be uniformly compressed with attendant formation and subsequent maintenance pie per ect e alla o e the s an th fixedi a'rr w n the an c ews. a p operly drawn up. In order that thewindow may be removed inemkargencies, a suitable socket rench fit in t s uar d e s .Qfthe c p .sq ws 65 s c rried wi 1 6.30.01 q pmen carried with th car. To withdraw the sash, the bolts 65are first removed whereupon said sash may be swung bodily inward andupward about the i e n ns. 5 o the posit on A in Fig.

Preparatory to theremoval of the sash it is,"of course, necessary to slide the bottom rod '36 of the curtain 31 upward and out of the top of the channels 32 and 3 3 in the lamb ' members 30, 31, which, together with the sill member 42, come away with the sash.

Except ashereinafter specifically pointed out the double sash window of Figs. 6-8 is of thesame general construction as the single sash embodi- 'ment shown in Figs 1-4. Therefore, in order to obviate the necessity for repetitive description,

corresponding parts in Figs, 6-8 have been iden- 'tified with the same reference numerals previously employed except for the addition, in each instance, of the letter a for convenience of distinction. As shown in Fig. 6, the upper and lower rails of the outer sash 52 are extended inwardly to receive the inner sash between them.

The side'jamb members 31a, 32a instead of beof the outer sash by screws.

ing integrally formed as in Figs. 1-4, are in this instance each composed of two sections 10, H and I2, 13, respectively. As shown, the sections 11,13 provide the grooves 32a, 33a for the curtain slides 34a, 35a, and are secured to the insides of the sections l0, 12 by screws 14, 15 with incidental provision of retaining shoulders at l6, 1! againstwhich the inner sash S bears the sections 10, 12 being fastened to the side rails The sash panes 26a and 16 are suitably secured in the respective sashes S, S and rendered weather-tight by molded rubber gaskete 18, 19 and 80, 8| of which the inner ones 19, 8| are in pressure contact to air-seal th inter-space between the panes.

The manner of removing and replacing the 7 double sash from the window in Figs. 6 and '7 is identical with that described in connection with Figs.'

'Having thus described our invention, we claim:

1. A window of the character described comprising a sash the frame of which bears perimetrically, with interposition of compressible weathering against the margin around a window aperture in a wall; an open pivot means whereby the sash is suspended from its top edge with capacity to be swung inward for convenience of removal; an inwardly projecting sill bar on the lower rail of the sash, said bar having a downwardly projecting portion to lap the inside face of the wall; and securing means engaging the downwardly projecting, portion of the sill for drawing the sill bar to the wall to fix the sash in position with the weathering compressed.

2. A window according to claim 1, constructed from metal, and in which the sill bar is recessed for reception and attachment thereto of a flush non-metallic sill block.

3. A window according'to claim 1,wherein the side rails of the sashcarry. jamb members with longitudinal grooves for guidance of 'a curtain.
