This invention relates to an automobile body construction of the composite type. The present practice in composite body p vbuilding is to rst form the skeleton Wooden '51 frame of the body, vso shaping and sizing the frame members that the contour of the body and the dimensions of the door and window openings will be defined thereby, and then covering said skeleton frame with sheet metal pane-l strips. This practice has required a large amountof steaming of the frame members to obtain curvature as well as much fine fitting and cutting thereof in defining vthe door and other openings.

l5 posed to eliminate the necessity of accurately constructing the frame by applying thereto a one piece sheet metal stamping having continuous openings formed therein, *they edges of which are flanged to define the j amb and the limits of the opening independently Of the frame. However, since stamping must be drawn to a depth substantially equal to the full depth of thevbody wall there still remains e necessity of imparting curvature to the frame members and also of having such members of relatively thick rectangular section.

The principal object of the present invention is to provide a composite body construction wherein the frame and its formation may be greatly simpliled and the rectangular section of the frame'members materially reduced. f

Another important Object is to provide a composite body construction wherein the contour of the body and the limits of the door and window openings will be defined by the sheet metal paneling substantially independently of the Wooden frame. v ,Y Y Y.

Other Objects and advantages will become apparent hereinafter. p

Itis proposed in vcarrying out the invention to construct` the frame of relatively thin rectangular section, the posts being' substantially Y are curved slightly to furnish inpart the longitudinal curvaturejof 'the body. The frame members may be joined together by butt or lap joints and reinforced by suitable brackets.

ture of the body may also be formed by the paneling. lt should be noted that the frame members are of relatively thin rectangular section thereby greatly reducing the weight of the body, as well as the cost of the material forming the same.

Combined with this frame is the paneling, which is made up of one piece stampings on each side of the body extending from the cowl to the rear part of the tonneau. The stampings, in the instance herein illustrated, are provided with front and rear door open-V ings 18 and 19, respectively, and quarter window openings 20. Of course, it is understood that the openings and their number will vary with the style of body, andthat although a sedan body is shown, the invention is appliccble to other Styles as well. The panel during the stampingoperation is formed at those portions flanking the sills, posts and headers with a general channel cross section.

The portion of the paneladjacentthe A post, while in the general form of a channel, has' the forward part of its base and its forward wall formed on a curveto impart symmetry andgrace -to the body. The rear part 23 of the base is inwardly oset to form a rabbet for the doorl overlap, while the rear wall 274: is provided with a rabbeted flange 25. The panel is secure to the A post by screws or other means extending through the forward wall 22vand the rabbeted flange 25. The forward wall is connected to the front face ofthe post, while-the rabbeted flange is connected to the outer face of the post, having its rear edge turned inwardly to effect a neat joint with Upon the inner face of the Vpost the windshield frame is secured, the forward edge of which extends around the postY in overlapping relation with'the forward wall At the B-C post the panel is of simple channel section, the'base 27 of which lies approximately on a line with the offset base part of the A post panel, so-that the doors n plane of the body. The forward and rearward walls 28 land 2.9 Aare each providedv with rabbeted flanges' `30 and 31 which are secured to the outerface of the post 12. l

The panelingV does not have a channel formation at the D post except at the location Vof the quarter window. It is formed at he other points with an inturned rabbeted flange 32 correspondingto the forward wall of the channel portion adjacentr the window opening. Thev lower part of the panel has the flange 32 forwardly extended and Secured to the bracket 15, in order to allow for the wheel l housing kick-upf. In forming the channel portion of the panel adj acent the window opening the base 33 of the channel is providedwith anV inward offset forming a rabbet for .the door-overlap while thei forward wally34y hasv the r'abbeted flange 35 corresponding to the similar flanges at the other post portions of the panel. The rear wall 36 extends straight inwardly and is secured to the rear face of the post 13 while the flange 35 is secured to the outer face thereof. Superimposed and secured upon the wall 36 is the guide 37 for the sliding` quarter window. Of course, if it was desired to use a laterally movable quarter window the panel could be formed with rabbeted offsets to providev a continuous jamb therefor.

The channelled portion ofthe panel adjacent the header has the inwardly offset base 38 forming a part of the continuous door and window frames, as well as the flanged side wall 39. yThe upper wall 4()v of the channel is attached to the top edge ofthe header Aand the flanged bottom wall 39 to the outer'side thereof. The roof panel 4:1 rests upon `the upper wall Al0 and has its inner` edge downwardly flanged and its outer edge in the 4form 'l o-f a bead, whereby the roof in effect embraces the top of the body;

Along the bottom of the panel.y the channel is formed of a downwardly and inwardly inclined base wall 42- and oppositely flangedl side walls i3 and 44. The flanges formed on such walls-are secured to the outside of the vsills andfhave inwardly bent portions overlying the top and bottomv edges of the sill.Y

ness of the wooden frame me1nbers, for example, the jamb isV formed in the front post region bythe portions 24 andll, at the in.- termediate post-by the portionsr29 or-,28 and 12. and at vtherear-door'post bythe por.-

tions 34 and. 13. In each case the width of:

the jainb is substantially the combined depth ofthe channel formed by rthe outer paneling and the thickness ofthe .wooden frame members. The foregoing description is thought to clearly bring out the-structural features of the embodiment. This invention will be seen to differ materially from other suggested constructions contemplating the .employmentA of paneling formed from one piece stampings so that continuous door` or other frame openings may be provided therein and their limits defined independently Aof the frame. In the heretofore suggested' constructions the stamping is-formed by a deep! draw so that the flanges of the openings will constitute jamb faces of a depth equal to the-,full depth of the body side. 'Howeven the deep drawing of the panel -is attended with difficulty and in addition, theY frame members being of relatively large rectangnlarcross section the weight of the body is increased. -In the present construction the panel, while deliningv the doorV andother openings so that accurate fits will beV obtained for the laterally movable closure members, does not require '13 gitudinally Vof the openings.

in forming the flanges The coacting between the frame and the sheathing or paneling is such that in effect the frame forms a light, thin inner panel for the outer panel, and reduces the depth of the draw of the latter by substantially the thickness of the frame members. This lis accomplished without losing the advantages of having the paneling define the closure openings, since the main or contacting surfaces of the jamb are formed by the panel, and such portions as are of wood are easily accessible. Therefore, the frame does not need to be constructed with that degree of accuracy in cutting and joining usually required in composite body constructions. Furthermore, since the major portion of the body curvature is furnished by the paneling the steaming of the wooden frame members is reduced to a minimum. Since the cross section of the frame members is reduced, the cost thereof, as well as their weight, is naturally lessened besides permitting such members to be of a lower gra-de stock. The construction also effects a still further economy, as well as a convenience, since the frame members eliminate the necessity for upholstery tacking strips.

The advantages of the one piece panel accurately dening the closure openings and capable of being formed in a single stamping operation are so apparent as not to require specific mention. The elimination of the deep draw has already been set forth.

The panel is by itself of great Strength but when connected to the frame, (or by another designation, its inner wooden panel), a box girder structure results at all essential parts of the body.

This construction is of particularadvantage in connection with modern automobile bodies which are of curved contour both vertically and horizontally. o The showing in Figure 1 and in the sections shown in the remaining gures clearly indicates'the application of the invention to this type of body, in which the outer paneling is curved lonand vertically to give the body such depth of draws its contour.
