VEHICLE BODY CONSTRUCTION.

Application filed November 5, 1921. Serial No. 512,960.

To all whom it may concern:

Be it known that we, CHARLEs M. MANLY, a citizen of the United States, residing at Richmond Hill, Queens County, New York, a and whose post-oilice address is No. 210 Abingdon Road, Richmond Hill, Queens County, New York, and JAMES MoGmsHAN, a subject of the King of England, residing at York, Pennsylvania, and whose postoliice' 1 address is No. 154 South Pine Street, York, Pennsylvania, have invented certain new and useful Improvements in Vehicle Body (Jonstructions, of which the following is a specification.

@ur invention relates to vehicle bodies and, particularly, to that class of bodies generally known as of the side panel commercial t pe.

The object of the invention, generally stated, is to improve the construction of the panels of such vehicle bodies with reference to making them capable of manufacture and assembly at a minimum costof material and labor, also strong and durable and at the same time free from rattling of the panels under the severe usage to which commercial vehicles are usually subjected.

The improvements are particularly applicable to knock-down bodies or those built in units in large quantities at factories and assembled only after being shipped to their final destination. and of comparatively light weight, although they may be advantageously employed in the construction of handmade bodies for either light or heavy vehicles, as will hereinafter appear. lln commercial bodies of the panel type, considerable ditliculty is encountered in keepin large size panels freetrom disagreeable an noisy rattling due to the thin sheet material of which the panel coverings are made vibrating either freely or against the posts which form part of the main framework of the panels. (onsiderable difliculty is experienced in this respect even where the large sheet-like members which cover the panels are made of wood. or other fibrous material, and the (hillculties are particularly marked where such sheet-like covering members are made of steel or other sheet metal. Since any sheet t thin material, whether wood or metal, if 'flahis very easily put into vibration, and when vibrating at certain speeds acts as a diaphragm producing sound even it the vibrating part does not strike any obstruction, and producing sound even more readily and volubly if it does strike an obstruction, it has been customary, in the construction of panel bodies to either curve or bow the vertical posts of the panel framework so that the sheet of covering material of the panel will be similarly bowed, thus reducing its tendency to vibrate, or, if the posts are left till straight and the panel flat, the thin panel volved in this application in panel construction for bodies therefore, reside particu larly in the cheap and elil'ective means which we employ in causing the sheet material covering of the panel to be bowed or bent and firmly held in such bowed or bent condition, and resulting in a substantial body and panel construction in which the vibrations and rattling are reduced to a minimum and which is otherwise peculiarly adapted for the use intended.

For a better understanding of the aboveindicated features and others which will hereinafter appear and as more specifically pointed out in the claims annexed hereto and forming a part of this specification refrence may be had to the accompanying drawings wherein:

Figure 1 is a perspective view of a side panel body-of the commercial type, with a portion of the sheet material covering one of the panels broken away to more clearly show the framework thereof.- Figure 2 is a vertical cross sectional view through the panel on line 2-2 of Fig. 1 looking in the direction of the arrow, and Fig. 3 is a horizontal sectional view otthe panel on the line 33 of Fig. 1 looking in the direction or? the arrow.

Referring to the drawings where like ENE y with the outer faces of the said posts.

numerals designate similar parts throughout, a vehicle body is illustrated which comprises, essentially, a platform or'base portion 1), a top portion (5) and two vertical side panels (6) and (6) which unite the said platform to the said top and support the latter on the platform, each of these main members, platform, roof and the side panels, being manufactured as individual units readily assembleable with and demountable from each other, and shipped as such units for later assembly at their destination. Since the two side panels are exact duplicates of each other except that they are rights and lefts, we will describe only one of them; viz,'the one designated by the numeral 6, similar parts of the other one being indicated by the same numerals as the corresponding part-s of the panel 6 except with the addition of the letter a as a suffix. In the panel 6 the rear vertical post (7) and the front vertical post (8) together with the several intermediate posts (9) and the post (9') are formed into a partial framework by the top stringer (10), and the intermediate stringers (11) and (11) which are morticed into eachother so that the outside faces of the said stringers and posts are substantially flush and coplanar with each other. The framework of the panel 6 is completed by a base stri 12 into which the lower end of each of the vertical posts is morticed, with the outer face of the base strip 12 flush and co-planar The various parts of the framing o the panel 6 are fastened together with suitable nails, screws or other fastening means indicated by the numeral 13. The lower end of the rear vertical post 7 is provided with a tang 7 which extends below the base strip 12 and is fastened to the platform 4 by the screw 13. The panel 6 is so placed on the platform 4 as to be flush with the outside edge thereof on which it rests. Secured to the rear post (7) and the intermediate posts (9) and post- (9) at a position about midway between the top stringer (l0) and intermediate stringer (11) is an upper batten (14) with its inner face pressing against and secured to the outer face of all the intermediate posts (9), the batten (14) thereby protruding to the extent of its thickness towards the outside of the said panel be yond the plane of the outer faces of the said posts. The left hand end of the said batten (14) is morticed into the post (7) so that its outer surface is flush with the said rear post (7), and it is similarly at its right-hand end morticed into the post (9') until its outer surface is flush with the outer surface of this post, attaching screws 13 being provided to securely hold the members together. Similarly a lower batten (15) is mounted against and protruding beyond the outer surface of all the intermediate posts (9) and the post (9') and is secured at its left-hand end to the post (7), into which it is morticed till its out-v side surface at this point is flush with the outside surface of the post (7), and the right-hand end of the said batten (15) is similarly morticed into the front post (8) to bring its outer surface at this oint flush with the outer surface of the said post (8). Mounted on the upper portion of the panelframing is an upper sheet panel covering (16) here shown broken but which in the finished construction extends in length from the post (9) to the rear post (7), and in width from the upper edge of the upper stringer (10) to the middle of the intermediate stringer (11). This sheet panel covering (16) is suitably secured by tacks or screws (18) to the upper stringer (10) and by similar tacks or screws (18) to the intermediate stringer (11), the said panel sheet covering (16) being thereby bowed or bent by the protruding batten (14) to the extent by which the said batten. (14) extends beyond the outer surface of the plane in which lie the outer surfaces of the said stringers and posts (Fig. 2). The said panel covering (16) is also secured to the rear post '(7) and to thepost (9) by fas tening means similar to the tacks or screws (18) and'is consequently bent in a longitudinal direct-ion at the two posts at the end of the panel. The bending of the panel covering (16) is purely longitudinal at the.

posts 7 and 9, and is purely vertical at the intermediate posts 9, with points at the ends of the panels between the posts 9 and 7 and the posts 9 and 9' having a combined longitudinal and vertical bend. Similarly a lower panel covering (19) is of a length extending from the front post (8) to the rear post (7 and is of a width extending from the middle of the lower stringer (11') .to the bottom of the base strip 12, the batten (15) causingthe panel covering (19) to be bent or bowed in a. manner similar to that just described for the upper panel covering (16). An intermediate panel covering (20) extends in length from the front post (,8) to the rear post (7), and in width from the middle of the intermediate stringer (11) to the middle of the lower stringer (11'), and is secured to the said posts and stringers by suitable fastening means such as screws or tacks 18). \Vhere this intermediate panel covering is as narrow as is here shown, it is found unnecessary to mounta batten on the framework underneath it, as its very narrow width makes it unnecessary to bend or, bow it to prevent it from vibrating. Should it be desirable, however, to make this intermediate panel wider for reasons of design or otherwise, it may be bent or bowed in a manner similar to the other panel coverings. In certain cases it may be desirable to combine the sheets 19 and 20 into one integral piece or 16 and 19, or even 16, 19,

and 20 may be combined, and generally the sheet coverings may be of any convenient number of parts and of any desired material. but the threeart arrangement shown and the use of s eet metal as covering material are preferred at present.

In order to give a proper finish to the panel and at the same time cover up the joints between the several sections of the panel covering as well as-the covering fastening means, a molding 21 which is indicated as of wood, but which is preferably of formed sheet metal, is mounted on the outside of the panel covering'and at the joints which the intermediate panel (20) makes ith the upper panel covering (16) and the lower panel covering (19), this molding being secured by nails or other suit- 7 able means to the stringers (11 and 11'). In the same way a piece of similar molding (22) is mounted at the bottom of the lower panel covering (19) and secured by nails or other suitable fastening means to the base (12), thereby giving a suitable finish to the lower edge of this panel covering. The upper edge of the panel covering (16) is not provided with a strip of molding, as the side frame member of the top is rabbeted out as shown at the top of Fig. 2, whereby an outer lip (24) of this side frame (23) of the top laps over and covers the upper edge of the panel covering (16). The panel is further finished by moldings similar. to 21 and 22 placed over the vertical joints between the ends of. the coverings and the post 7 and also on the vertical post 8 to give the proper finish thereto, and a. similar finishing molding may be positioned on the upper part of postt) to cover up the joint with the end of sheet covering 16; these moldings being omitted from the drawings 'for convenience in illustration.

In general each section of panel covering material needs to be secured only to such members of the framing as are the boundary members for that section, thus obviating the disfiguring ormar-ring of the otherwise smooth surface of the panel covering except at its edges, where it is covered by a finishing molding. However. in securing the desired style or appearance for the finished panel, it may be desired to have the panel appear to comprise more divisions than is found best in the panel covering material from the standpoint of economy in manufacturing. It is therefore to be understood that the panel covering is secured to panel boundary members wherever there is a division or edge of the said covering, or finishing molding is applied to give the appearance of divison's in the said covering.

The body and panel thus constructed have &

prove-n in service to be peculiarly free from the rattling and vibrations and noises consequent therefrom experienced in certain prior types ofbody construction. Moreover the same may be economically manufactured and assembled on a quantity production basis.
