My invention relates to pressed metal'win- .dow framesof the type commonly found in closed body vehicles but it is not improbable that-other adaptations maybe found'for 1t.

5 More specifically, it relates to those construc- .tions in which it is sought to reducev to a minimum the opaque projections of the Window frames as taken from the interior of the car. Therehas been of recent months a great for.-

40 Ward movement in theart ofbodybullding having as its principal aim't'he marked in- =crease3of the range .of vision from Within the car whereby the comfort of-passengersand their safety is greatly enhanced. This move- I ment has resulted int-he employmentof very thin pressed metalisections in window frames particularly indoor Windowframesyvhere the {triple considerations imposed by window mounting, door frame and door posts are more liable to multiply the area of opaque projection than cases where Window frames .alone are involved. In one type of car with which I am most familiar, this enideavor has resulted in a Windowv or door .25 frame the main body section member of which is of .2 form. The ma-inweb is disposed transversely, the glass run channelis formed upon it,and :the arms of the Z section are respectively constituted the outer of them the-onteredoor amb overlap upon thebody frame members, and the ,inner of .themthe mean-s of securingthe inner paneling or upholstery, and oneside wall of the glass run -.channel. These rails as-well .as other forms .of nailswithwhichl am.. familiar have re- .qnired'theemployment-of metal of a substantialgauge in orderto give them the requlslte stifl-ness without increasing the area of opaque projection, p 1 i p It is the principal aim of my invention to give such greater strength without. increasing the gauge of the metal and without increasingthe area-of opaque projection. I attain this object by employing a subordinate reinforcingsectiommember .Ofzit depth not exceeding thedepth of the glass run channel. Thedepth of this glass run'channel is commonly determined the'length of the inner arm of the .Z-section. Somuch depth is necessary in order topr-operly align the glass haveconcei-ved therefore that I" may construct the window rail of-acompoundsection the total depth of which does not exceed the depth' of the Windovvglass run channel without increasing the opaque projection.

In the embodiment of my invention which I illustrateiherein'l have attained this princhannel, preferably in the form of a unitary panel stamping and of a depth-not exceeding cipally by applying-mouth down to the main -Web of the Z-section of the window rail a t-hatof the glass run channel. Moreover, I

have simplified the structure while so strengthening it by constituting the inner side Wall of-the channel the outer side Wall of the window glassnun, eliminating the necessity for the provision ofspecial angle members for that purpose. Still further, in the exposedexterior of the window glass frame, I have changed the configuration of the reinforcin'gchannel of the newcompound section to vgive it a finished bead-like appearance thereby markedly improving the general appearance of thewindow frame at large.

In the drawings: 7 z i Fig. l is a sideelevationof adoor, frame having a Window in its upper portion taken from the interior. I V I j Figs. 2 ,to 6 are respectively cross-sections on lines .of corresponding numbers appearing in Fig. 1 .and in the direction of applied arrows. v g

member ofz cross-section hasits main body identified'jbythe' numeral 10, its outer arm designated '11,, and itsinner; armdesignated 12; While the reinforcing subordinate section member of channel form has the bottom of and its outer sidewall desig nated 15. Itwillbe quite apparent that the side, andtop rails are of compound section throughout their upper. portions, being formed ineach case by the principal section member and the subordinate or reinforcing section member. The lowerportions', however, are ofthe usual sections shown in Figs.

I Throughout the drawings, the mam sectlon its channel designated-I13, its inner side Wall designated 14 2 and 3, a section of greater height than that of the upper portions.

The outer arm 11 of the main section mem ber of 2 form constitutes in each case the perimetral overlap of the frame across the door j amb. Throughout the frame also the transversely extending main body of the Z section constitutes the transverse main body Web of. the pressed metal rail. Similarly, the inner arm 12 of this main section member constitutes in the upper reaches the inner side wall of a glass run channel 16. In the lower reaches it constitutes a means of securing the inner panel (of which the lockboard panel 17 is an example) to the inner face of the-door frame and a support too for the upholstery (not shown). The length of arm 12 is primarily adjusted in the upper reaches of the rail surrounding the window opening 17 to the practical depth of the window glass channel 16, this depth being that minimum value consistent with eflicient guiding of the glass whereby the opaque projection is cut down to a minimum.

The channel section subordinate section member 13, 14, 15, is attached mouth down to the plane inner face of the plane form main body web 10 of the Z section in the upper reaches. In the form shown inFigs. 7 to 9, member 13, 14, is of a Width less than the total height of the plane main body web 10 of the 2 section, less by an amount substantially equal to the width of the glass run channel 16. Its side wall 14 adjacent to the inner arm 12 of the Z section forms with the arm 12 the glass run channel 16. This arm is provided with an inwardly extended side wall flange 18 by means of which the channel section reinforcing member is spot welded to the plane face ofthe web 10. This flange 18 is of such width that it spaces the side wall 14 the proper distance from the arm 12 to give the glass run channel its proper Width. In this function, it'acts as a spacing member in the weldingassembly. The opposite side wall. 15 is substantially in line with the outer jamb overlap arms 11 of the main 2 section, is extended laterally to outwardly overlap these arms and then inwardly around the outerends of the arms as at 19 where they are welded thereto, preferably by arc-welding on the inside to the arms 11 thereby avoiding any danger of marring the exterior as would be occasioned if spotwelding were used through the three thicknesses.

[Atthe top rail (see Fig. 9)v the main Z section 10, 11, 12 is of less height than the corresponding sections of the body rails, the height of which in the embodiment shown is substantially uniform. The window glass run 16 is here formed by a supplementary header member 20 of angle cross section having one branch 21 removably secured to the main body web 10 of the header rail and the ther branch 22 depending substantially parallel with the inner arm 12 of the Z section and spaced a sufiicient distance therefrom to give the proper glass run channel width to channel 16. The reinforcing channel member in this case has its'side walls 14, 15 respectively extended to outwardly overlie the respective arms 12, 11 of the main section of Z form. The inner side wall 14 is spot welded to the inner arm 12, while the outer extended arm 15 isturned around the outer overlap flange 11 as at 19 and arc-welded to the inner face of the arm as in the other instance.

In the form shown in Figs. 4 to 6 reinforcing channel section member 13, 14, 15, is of reduced width. The side wall 15 is moved inwardly in this reduction of channel width. In these upper portions it is extended first laterally parallel and cont-iguous to the plane form main body web 10- of the main section of Z form, then outwardly and inwardly as at 19 around the outer overlap arm 17. Moreover, the bottom Wall 13 a'nd'the side wall 15 are merged into each other to the substantial elimination of the angle between them with the result that the section in these upper lengths of the rails is given exteriorly a bead-like appearance, the bottom wall 13 and the sidewall 15 having an exteriorly convex form. The construction at the top rail is similar as clearly shown in Fig. 6.

In each case, I have retained adepth of channel section in the subordinate reinforcing member 13, 14, 15 not exceeding the depth of the glass run channel 16. The total body cross-section of the door, therefore, excluding the outer overlap flange is of a depth not substantially exceeding the required depth of section'of the glass run channel. The opaque projection cannot possibly be increased therefore by such means. On the other hand, however, the strength of'the frame for a given weight is very greatly increased, for especially in the sections shown in Figs. 7 to 9, the combined section of the main body 10 of the principal section and the channel of the reinforcing section is of box form, of very much greater thickness than the thickness of gauge of either of the pressed metal section members which form it. As is well known, the box section'gives a very great strength for a given weight. The combined section in the form of Figs. 4 to 6 is likewise of box form, though in this case it is of reduced area and approaches a triangular shape in lieu of a rectangular shape. While the strength of the triangular section of reduced area is somewhat less than that of the rectangular section, yet I am able to achieve a very substantial gain in strength and reduction in weight by reason of the construction. This is augmented by the extended side wall 15 and its extensive overlap with the outer door overlap flange 11.

Moreover, by reason of the fact that the bot tom and side Walls 13 and 15 are merged nto each other and the outer angle ellminated,

the range of vision defined by line 23 tangent to the bottom 13 and the juncture of the arm 11 indicated by possible with earlier types weaker sections, is fully reand side Wall 15 of the reinforcing channels, presenting the bead-- like appearance, and by reason of the fine exterior finish afforded by the sheathing of the rather heavier and coarser main section 10, by the outer and overlapextensionl!) of the reinforcing section member. Light gauged material with inferior surfacing face of the main member and secured at its opposite edges to theoppositely extending arms of the Z. p In testimony whereof I hereunto aflix my signature.

merger in various ways may be used with economy in themam section members 10, 11, 12, While thin gauge metal of highly finished and face may be used for the subordinate and reinforcing section members 13, 14', 15. The markedly increased strength, the unimpaired vision, and the fine contour lines and superior exterior finish are actually obtained with substantial economy of metal due jointly to a retention of the actual weight of metal at a minimum value and the use of a cheaper metal, less expensive to fabricate for the major portion of that weight.

Though my invention is simple, it has such substantial merit in its own field that ingenuity will without doubt be directed to circumvent it. This cannot but result in quite a number of ically the same as my own invention. These the annexed claims should cover as fully as,

they cover the embodiment herein shown.

hat I claim is:

1. A top rail for doors of closed vehicle bodies comprising a main member having-a transverse portion of web cross section,

flanged at its outer and inner edges, and a panel stamping of hollow form having one side open appliedwith its open side to the inner face of the main member and secured at its opposite edges to the flanges of said main member. 1

2. In a door, the combination with spaced pillars and a cross bar, of a panel secured to said pillars and having a finish strip at its upper end partially enclosing said cross bar, and a header secured to said cross bar and finish strip and cooperating with said finish strip to conceal said cross bar.

3. A top rail for doors of closed vehicle bodies comprising a main member of web cross section of simple Z-form, and a panel stamping of hollow form having one side open applied with its open side to the inner fine grained sursolutions which are gener
