Abstract: 675,289. Vehicle frames. HUDSON MOTOR CAR CO. April 6, 1949 [July 22, 1948], No. 9415/49. Class 108(i) A combined body and chassis frame comprises front and rear sections A and B, Figs. 1 and 3, which are welded together during final assembly. The section B has two main longitudinals 20, each of box section extending to the wheel housings, and the members 20 are secured to laterally spaced rear members 23 also of box section welded to a box section member 24. The side members 20 are connected together transversely by a box section member 25 extending beneath the front edge of the rear seat, which seat is mounted upon a tray 26 rigidly secured at its front edge to the top of member 25. Box section members 27 are braced by members 28 to the member 25 and to a cross-frame member 29 positioned near wheel housings 30, each of which housings comprises a pair of dished metal sections 31, 32, welded together. The longitudinals 20 are joined in advance of the member 25 by an upwardly opening channel member 39. Main pillars 33, 34 and 35, co-operate with headers 36 and the members 20 to permit the hinging of front and rear doors 37, 38, Figs. 4 and 5 (not shown). A rear seat floor pan 40, Fig. 6, having a raised portion 41 extends transversely between the longitudinals 20. The portion of the pan at opposite sides of the tunnel 41 extends transversely between the members 20, and the portion of the pan at opposite sides of the tunnel 41 slopes outwardly and downwardly, the outer edges being flanged and welded to the longitudinals 20. The rear edge of the pan is welded to transverse members 42, Fig. 2, (not shown), which in turn are welded to the member 25. The portions of the pan 40 on either side of the tunnel 41 are depressed substantially below the upper edges of the members 20, 25 and are welded to and supported by longitudinal channel-shaped frame members 44 which are joined by cross-ties 45, 46, Fig. 4, (not shown). Mounted upon the transverse member 39 is a front seat tray 43 having a rearward flange which is welded to the pan 40. The front seat floor pan comprises two member 47, and a central member 48 bent upwardly at 48a and welded to the members 47 which in turn are welded to the members 20. The front seat pan is also welded to the tray 43 and to the dash. Attached to the front ends of the members 20 are stub extensions 50 forming locating abutments and connections for the units A and B. The unit A comprises side members 51 of box section joined at their front ends by a box section cross member 52. The members 51 are provided with extensions 51a which extend rearwardly and inwardly between the members 20, the rear ends of these extensions being rigidly attached to the bottom of the cross member 39 when the units A and B are assembled together. The extensions 51a are rigidly connected with the members 50 by means of a cross frame member 53 which is in the form of an inverted U-shaped channel and extends through and is welded to slots in the extensions 51a. During final assembly the section A is telescoped within the rear section B and the parts 51b welded with the members 50. At the same time the ends of the extensions 51a are welded to the member 39. Specification 674,175, [Group XXXI], is referred to for this assembling operation.
