NYSTROM, oroHIoAGo, ILLINOIS CAR-VWINDYOW CONSTRUCTION epplieationffiledJanuary 15,1927. Seria1rNo. 1 61 39Q invention relatesetoan' improved window construction for railroad passenger cars, streetcars andinterurban cars; the inventionhaving for its object the provision 5 of a construction, controllable by the noonpant of the seat or berthwhereby suitable v'e'ntilation and ingress of air may be obtained; while at the same time providing-a constructionwhereb'y a maximum vision is 10 obtained in a 'givenwindo'w opening and a suitable avenue vis providedto permit communication between'the occupant of'the car and an individual on the outside withoutnecessitating opening of the outside window;

15 The objectsand' advantages oii my-invention will be readily comprehended from the following detailed description j of the accompanying drawings, wherein I Figure 1 is an inside elevatlon of a section i j 20 of railroad car provided with my improved 7 windowconstruction;'with the floor shown in section and the underfram'e omitted.

Figure 2 is anoutside elevation of a pair of windows,partially broken awayas is also true of the side wallofthe car. 4

, Figure 3' is a vertical section of hey improved window construction. ,o

Figure 4 is aperspective view of a portion while the ledge portion of the fra'meis' formed to provide an air chamber having air ducts or passages open to atmosphere.

The invention also contemplates means wherebyathe outer window is pivotally secured in place; whilethe" inner window involves means operable from the car interior wherebyeasy and positive operation of the of the upper end of awindowscreen em- Figure 7 is a sectional view" taken sub-- inner window by the occupant "may behad;

while atfthe same time simultaneous positioning of a window-screen may be accomplished 'yv. "1'

f As my invention ismore especially intended, for use in connection 'Withfsleeping cars, 5 the exemplification discloses a'section of a sleeper, namely with the opposing seats being "shown at 15, "15, in 'Figure'lyarr'angedi as usual, adj acent; to, a pair of windows gener-.

allyindic'ated at 16-, 16 in said ffigure, with 6 the Windowat the'left'bein sho'wnpartially raised and the opening there eneath provided with a suitable mesh screen indicated at 17. -InFigure' 3, 18 andj19 represent portions ofthe outer andinner car walls, spaced apart as usual and'provided With an openingeto I receive my improved window frame construcnon 20 ,'h'aving an opening in thetop to per- 7 mit P gerofth inner window-sash' 2l when the latter israised; r

"The inner windowesash 21 at one side is l preferably" providedjwith a rack 22'and a' bearing rolle'r 23; while'the opposite side of the sash is also shown provided with a bearing roller 24 which is preferably supported by an upwardly disposed. projection 25' formed on theupper end of the inner: sash to receive any thrusts that may be encountered in t'he'operation of thewi'ndow. The side portion of the frameQO, which is preferably of metal, is formed to provides, 7

"sash receiving groove'or channel 26 of'de pth suiiicient to receive the bearing rollers" asiwell v as a portion of the side members of'the wine dow-sash. The. frame 20' is also formedto provide the intermediate bentportion whereby an abutting shoulder 27 is provided for the outerv sash 28, which is thereby maintained in spaced relation with the inner sash-21; I

' The car interior" side of the window-frame 20 is also it'or'mediwith a small vertically disposed groove 1 or socket-at- 29 to provide a slide-way fortheside frames of the windowscreen 17 the grooves29 being arranged-in close/proximity to the window slide-way, as shown in Figure 5.

I The frame member 20 at the right Figure 5, at a'point coincident with; the chan'nel26, and preferably adjacent to the upper end of the-innerwindowesa h 21; is provided rwitha;

tion su suitable opening for passage of a segment or portion of a pinion 30 in order that the latter may mesh with the rack 22 formed on the ad jacent side of the inner window sash, The pinion is mounted in the car side wall by means of a suitable bracket as at 31 in Figure 5; with the journalof the pinionextending through to the, car-interior where l'QliSiOIHH-Bd to receive a crank 32.

It is apparent that the inner window 21' may be easily raised or1loweredJoyapropertie-v eration of the crank 82 and that the rollers 23,

24 will hold the sash against lateral move ment and cause the window to slide easily.

The lower part or ledge :of the window frame comprises a hollow or chambered nor- 601133, The extremeends of this chamber are open at '34; 34 to the car exterior; the

A further purpose in tapering or sloping the'air chamber '33 is to provide a self-cleaning ventilator! It. will be seen that by sloping or disposing the outer ends of the chamber 33*downwardly toward the openings 34,
