This invention relates to improvements in the construction of motor vehicle bodies, especially those of busses and particularly deals with the mounting and support of the framework of the body relative to the main frames of the chassis of the vehicle.

The principal object of my invention is to mount the body frames on the chassis frame in such a manner that the finished body will be lighter than those at present constructed, while at the same time it will be stronger and not so likely to weave and twist.

"Also the center of gravity of the vehicle is lowered which of course adds to the safety of operation.

can be kept lower than is now possible, while at the same time the entire width between the side frames of the body may be utilized for floor space without any obstructions being present.

A further object of the invention is to provide a simple and inexpensive device and yet one which will be exceedingly efiective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of ref- 3 erence indicate corresponding parts in the several views:

Fig. 1 is a fragmentary perspective elevation of the body framework of a motor bus constructed according to my improved method.

Fig. 2 is a fragmentary cross section of the framework.

Referring now more particularly to the characters of reference on the drawings, the main side frames 1 of the vehicle (of which there are two as usual) are of channel iron, the channel openings facing each other. Extending across these frames at longitudinally spaced intervals are upwardly facing channels 2, which project outwardly of the frames 1 for some distance and are then turned down as at 3 to form end extensions projecting below the frames 1 a certain distance. In these extensions, the side'flanges 4: of course face outwardly. The horizontal portions of Further the floor of the car the channels 2 are filled from end toend with strips 5 of oak or the like which not onl serve to stifl'en the channels but provi e means for supporting and securing the floor planks 6. The side uprights or posts 7 of the body frame, of oak, ash, or similar material,

extend unbroken from the bottom of the ex-.. tensions 3 to the roof, being mortised at their upper ends into a longitudinal stringer 8 which is bolted thereto. The roof carlins 9 are mortised into this stringer immediately adjacent the posts and are braced to said stringer by angle irons 10.

At a suitableheight between the stringer 8 and the frame 1 a heavy horizontal stringer 11 is inortised into the corresponding posts,- the space outlined between the adjacent posts and the stringers 8 and 11 representing the window area of the body.

At the lower ends of the posts and channel extensions 3 the side flanges 4 are cut away for a certain height and the adjacent faces of the posts are also cut away as shown to receive a bottom stringer 12 which thus restsbetween the posts and channel extensions and is suitably bolted to both. The side posts are provided on their inner faces with horizontal ledges or shoulders 13 which rest on the adjacent ends of the strips 5 and prevent downward movement of the posts without depending on the holding bolts. The posts fit closely between the side flanges 4;, the latter acting as braces for the posts and thus pre- 7 venting swaying thereof.

The channels are additionally strengthened along their overhanging portions and the frames 1 are also held from side twisting by means of Z braces 14 of heavy strap iron which extend from under each frame 1 to adjacent the outer ends of the horizontal channels 2. Bolts 15 are placed through the brace strap and through the channel and filler on each side of the frame 1, and other bolts 16 connect the outer ends of the braces to the channel and filler.

While I have shown and described the complete construction of the body framing from top to bottom, my invention deals solely with the mounting of the side posts onto the chassis frame. I

From the foregoin description itwill be readily seen that I ave roduced such a device as substantially ful s the objects of the invention as set forth herein,

5 While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resortedto as do not orm a departure from the spirit of the invention,

as defined by the appended claims,

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is: v

1. In car body construction, a main frame member, cross members secured thereto at intervals and projecting beyond the outer face thereof for some distance, said cross members terminating in downward extensions, body frame posts abutted against and projecting upwardly from the extensions, and

* a longitudinal bottom stringer disposed between the cross members and the posts at their lower ends and secured to the posts; the posts being cut out to receive the strin er.

2. A structure as in claim 1, in which the cross members are provided with side flanges above the stringer which engage the sides of the posts. 1

3. In car body construction, a main 1ongie0 tudinal frame member, spaced cross members projecting outwardly therefrom some distance and terminating in downward extensions, body posts secured to and projecting upwardly from the different extensions and a longitudinal bottom stringer lying with its major axis in a vertical plane, extending between the different posts at their lower ends and secured in common to the posts and cross-member extensions. 7

In testimony whereof I aflix my signature.
