This inventionA relates to railway car windows; and it is concerned more particularly with windows for metallic passenger coaches.

In the construction of metallic railway cars,

the walls are made hollow with inner and outer sheathing plates secured to roof supporting'. posts along opposite sides of the car body; and openings are'provided in the side walls into which the windows are subsequently placed. Heretofore it has been customary to nt the frames of the windows piece by piece into the openings provided for them in the car body. Such individual fitting of metallic parts was tedious and slow, as well as costly from the standpoint of the labor involved; and it frequently happened that, due to inaccuracies in fitting, the frames would not be perfectly rectangular and therefore interfered with free movement of the sashes. Windows imperfectly constructed under the conditions noted were, moreover diflicult to make weathertight.

Considered from the broadest aspect, my invention is directed toward overcoming the drawbacks whereto reference has been made, which desideratum I make possible of realization in practice through provision of a sliding sash window characterized by a pre-assembled rigid frame, which, for convenience of nomenclature, I term an adapter frame, the same being designed for insertion into the window opening of the car body with its head rail underlapping the top edge of the opening and its bottom rail resting on the sill edge of the opening, and having outward attaching flanges on its jam-b rails to marginally overlap the side edges of the window.

Other objects and attendant advantages will be manifest from the detailed description following in connection with the attached drawings, wherein Fig. I is a fragmentary view showing, in part, the side elevation of a railway passenger car body equipped with windows constructed in accordance with my invention, one of the window openings having been left unframed.

Fig. II is a fragmentary detail sectional view drawn to a larger scale, and taken as indicated by the arrows II-II in Fig. I crosswise of the unframed window opening.

Fig. III is a view similar to Fig. II, but taken -crosswise of one of the completed windows, as

indicated by the arrows III-III in Fig. I.

Fig. IV is a vertical sectional view taken as indicated by the arrows IV-IV in Fig. I, through the unframed window opening of the car body.

Fig. V is a view like Fig. IV taken as indicated by the arrows V-V in Fig. I, through a completed window.V

Fig. VI shows a perspective view of the adapter frame of my improved window.

Figs. VII, VIII and IX are views corresponding respectively to Figs. II, III and V, showing a double sash car window embodying my invention; and

Fig. X is a perspective view of the adapter frame of the double sash window.

Referring first to Figs. I-V wherein I have illustrated a single sash window structure embodying the present invention, the car body therein shown for the purposes of exemplication is of steel construction and formed in its hollow sides with horizontally aligned window openings l0 whereof one is left unframed in Figs. I, II and 70 IV. As shown, these window openings 10 are set apart between channel section roof supporting posts 11 and 12 concealed in the hollows of each side wall of the car body, the wider posts of the type 11 alternating with the narrower posts of 75 the type 12. To the frontal face of each post 11 is secured a vertical outer sheathing plate 13 which has substantial projection beyond opposite sides of the posts; and to the lateral anges 14 of said post is secured the vertical inner sheathing plate 15. From Fig. II it will be noted that the posts 12 are reversely positioned with regard to the posts 11, and each has a vertical outer sheathing plate 16 secured to its lateral flanges 17. At the bottom of each window opening 10 there is incorporated with the side wall of the car body, a sill supporting member 18 of hollow channel section having a relatively deep depending frontal flange 19 which marginally overlaps the outer sheathing panel 20, see Fig. IV. As shown, the sill supporting member 18 has a bevel 21 corresponding to the top slope of a supplemental sill rail 22 which extends the full length of the car body and which is secured by meansy of rivets 23. A short depending ange 24 along the rear edge of the sill supporting member 18 is overlapped by the lower horizontal inner sheathing panel 25 of the car body and secured by rivets 26 which also serve to secure a cover angle strip27. 'I'he upper horizontal outside sheathing or eave plate 100 28 above the window openings 10 is outwardly joggled along its lower edge with formation of a square cap bead 29 which, like the sill bar 22, extends the full length of the car body.

Coming now to my improved single sash win- 105 dow structure, the same will be observed to comprise an adapter frame 30 which is illustrated in perspective in Fig. VI. As shown, the head rail 31 of this adapter frame 30 is of L cross section,

with a forwardly directed horizontal fiange 31a 110 and an upward vertical flange 315, the opposite ends of said head rail abutting the jamb rails 32 whereof the top ends are L-notched as at 33 to v correspond to the cross sectional configuration of said head rail. Referring to Figs. III and VI, the jamb rails 32 of the adapter frame 30 are of l'section with outward attaching flanges 32a at right angles to the median webs 32b and with inward sash guiding flanges 32e at an acute angle to said median webs. The bottornr rail 34 of the 4adapter frame 30 is of right angle section with a comparatively deep horizontal flange 34a and a shorter frontal flange 34h which depends from said horizontal` flange; and, like the top rail 31, said bottom rail has its ends abutting the jamb rails 32. Both the head and bottom rails 3l and 34 of the adapter frame 30 are narrower as regards depth than the side or jamb rails 32; and '1t is to be particularly noted that the horizontal flange 31a of the head rail is flush with the attaching flanges 32a of the jamb rails 32 at the front of the frame; while at the rear of the frame, the edge of the horizontal flange 34a of the bottom rail 34 is flush with the edges of the median webs 3212' of the jamb rails, the described relationship being best illustrated in Figs. III and V. The head and bottom rails 31 and 34 of the adapter frame are thus disposed in spaced vertical planes for a reason which Will be obvious from further description. The parts constituting the adapter frame may be riveted one to another; but, for the sake of permanent rigidity, I prefer to weld them together at the regions of mutual abutment.

As a means to support adjunctive parts of the Window, I have provided in each instance brackets, such as shown at 35 and 36, pairs of which are securedby rivets or bolts respectively to opposite sides of the posts 11 and 12 within the window openings 10, said brackets having their opposing faces correspondingly stepped respectively as at 37, 38 and 39.

In placin'g an adapter frame 30 into one of the window openings 10 of the car body, the top rail 31 ofA such frame is hooked in under the inward flange 29a of the cap bead 29 on the eave plate 28 as indicated in dot and dash lines in Fig. IV, and the frame thereupon swung inward until the lateral attaching flanges 32a of its jamb rails 32 engage the vertical sheathing plates 13, 16 respectively on to the posts l1 and 12. With this accomplished, the adapter frame 30 is allowedy to drop so that the depending flange 34h of its bottom rail 34 rests evenly on the bevel 21 of the sill supporting member 18, whereupon the'frame is secured by means of screws 35a and 36a which take into the faces 3'7 of the brackets 35 and 36. To further secure the adapter frame 30, rivets 13a and 16a are passed through the attaching flanges 32a of the jamb rails 32 and the overlapped margins of the vertical outer sheathing plates 13, 16. Incidentally, ,caulking material is interposed between the inward flange 29a of the cave plate 28-and the horizontal flange 31a of the top rail 31 of the adapter frame 30 as conventionally indicated at 40 in Fig. V, and between the attaching fianges 32a of the jamb rails 32 and the outer vertical sheathing plates 13, 16 as at 41 in Fig. III, to insure weather-tightness at these regions. When necessary for the proper registry between preallocated rivet holes in the plates 13 and 16 and the attaching flanges 32e of the adapter frame jamb rails 32, shims are jamb rails as indicated by the heavy lines at S, S' in Fig. III.

With the adapter frame 30 now permanently secured, a sill bar 42 of wood is placed and made fast with screws 43 and 44 (Fig. V) to the sill supporting member 18 and the bottom rail 34 of said adapter frame. A finishing molding strip 45 (Fig. III) of angle cross section is next secured to the faces 38 and 39 of the brackets 35 on the post 11, by means of screws 46, said molding being so shaped cross sectionally and proportioned as to hide the rivets whereby the vertical inner sheathing plate 15 is fastened to the post. At the opposite side of the window opening 10, a box molding 47 is placed .ovei thepost 12 as shown in Fig. III and is secured to the faces 38 and 39 of the brackets 36 at opposite sides of such post by means of screws 48. To accommodate a roller curtain 50 (Fig. V) for the window, a housing 5l of sheet metal is inserted into the hollow of the side wall of the car. body above the window opening. After this, the sash shown at 52 in Figs. III and V is introduced from the inside of 'the car in such manner that its top edge is engaged between the head rail 31 of the adapter frame 30 and an opposing hollow flange 53 formed on the curtain housing 51, said flange 53 being surfaced with weathering material 54. Guide strips 55 for the sash 52 are next secured to the brackets 35, 36 on the posts 11 and 12 over the sides of the moldings 45, 47 by means of screws 56, said guide strips, it will be noted, being of irregular cross section with formation of opposing flanges 57 to cooperate with the inward guide flanges 32e of the jamb rails 32 or" the adapter frame 30 in retaining the sash. A groove of definite width for guidance of the sash 52 is determined through engagement of shoulders 58 of the guide strips 55 with the inner edges of the median webs 32h of the jamb rails 32 of the adapter frame 30. The channels 59 in the guide strips 55 serve for the followers 60 attached to the lower edge of the curtain 50. The window is finished at the top by inter-connecting moldings 61, 62 (Fig. V), the first of which covers the access opening into the curtain roller housing 51 while the secondhides the housing 51 as well as the longitudinal angle 63 secured to the top inside sheathing plate 64 of the car body. The window sash frame 52 is in ythis instance constructed from metal, and as shown in Fig. V, it is provided along its bottom with a downward frontal tongue projection 65 to overlap the bottom rail 34 of the adapter frame 30. Spring weather strips 67, 66 are secured to the side and bottom edges of the sash 52 to insure weather- '70, and the brackets 135 and 136 on the car body posts 111 and 112 whereto said frame is secured by screws 13511 and 136a, are somewhat dierently fashioned in view of this change, as will be apparent by comparison of Figs. VIII and X with Figs. III and VI. As shown in Figs. IX and X, the head rail 131 of the adapter frame interposed between the side flanges 325 pf said .130 iS made double, i. e., composed of two spaced reversely arranged components '71 and 131, both of irregular L-cross section with oppositely directed horizontal anges '71a and 131a, and up- -ward fianges '71b and 131b, and with longitudinal recesses '73, 133 at the regions of the junctures between said horizontal and vertical fianges. Also as in the rst embodiment, the jamb rails 132 are of irregular T-cross section with oppositely directed lateral flanges 132a to lap the face plates 113 and 116 on the posts 111, 112 of the car body, and with inward flanges 132e for engagement by the outer sash '70. The bottom or sill rail 134 of adapter frame 130, in` this instance, cornpletely covers the top of the sill supporting member 118 of the window opening 110 and is cross sectionally configured in conformity with the latter (see Fig. IX), the bevel at 121 being considerably broader than the bevel 21 in Figs. IV and V, so that the corresponding drain bevel 134.1: of the rail 134 may serve for both the sashes 70 and 152. Also, as shown in Fig. IX, the forward I edge of the sill rail 134 of the frame 13 0 slightly overlaps the juncture plane between the vertical face of the sill member 118 and the abutting face of the external wooden sill bar 122. At 1341/, the rail 134 of the frame 130 is formed with an upward flange which is overlapped by the inner sash 152 when the latter is in the closed position of Fig. IX, and which, with the horizontal portion 134e of the said rail, forms a seat for the wooden finishing sill strip 142 interiorly of the car. Hollow square section parting strips '75 and 155 suitably secured to the in-sides of the jamb rails 132 of the adapter frame 130 (see Fig. VIII), in conjunction with the inward flanges 132e of said jamb rails, define vertical channels forv guidance of the sashes '70 and 152.

For assurance of air-tightness at the sides, the outer sash '70 is provided, see Fig. VIII, with exible metal weathering strips .'76 which are similar to the weathering strips 67 of Fig. III, and which'strips have their free edges bent outwardly to engage vertical grooves '7'7 in the inward flanges 132e ofthe jamb rails 132 of the adapter frame 130; while the weathering strips 1'76 on the inner sash 152 bear against the parting strips 155. At their tops, the sashes '70 and 152 are fitted with folded weather strips '78 and 154 whereof the extended looped portions lap the sloping portions of the head rail components '71 and 131 of the adapter frame 130 occasioned by the recessing at '73 and 133 as shown in Fig. IX. The bottom of the outer sash '70 has a yielding weathering strip '79 of rubber or the like which is adapted to bear against the sill rail 134 of the adapter frame 130, and which is formed with an outward flap '79a capable of shedding rainwater. The weathering strip 166 at the bottom of the inner sash 152 is like the strip '79 except for omission of a flap.

The followers 160 for the curtain or shade 150 are in this instance guided in grooves afforded by angle flanges '75a of the parting strips '75 (see Figs. VIII and IX) and the curtain roller is concealed within the hollow of -a finishing molding 162 which closely resembles the molding 62 of Fig. V.

In the case of the double sash window construction, it will be noted that the upward flange 13117 of the head rail 131k of the adapted frame 130,

is secured to the face plate 128 of the car body by rivets 128a, whereas the side flanges 132a, of the jamb rails'132 are left unattached, although if desired, they may be riveted fast like the flanges 32a of the iirst described embodiment.

In order to avoid repetitive description, the

parts not specifically referred to in connection with Figs. VII-X have been identified by numerals higher in each case by a hundred than those used to designate corresponding parts in the first described single sash window embodiment of my invention.

From the foregoing it will be seen that the double sash window form of my invention embodies the same structural characteristics which are novel to the first described single sash form, and which favor the attainment of the several advantages pointed out in the introductory portionof this specification.
