16 Claims. (01. 29-152) This invention relates to newand useful improvements in the manufacture of automobile frames and more particularly the type in which the component parts are of tubular or box sec- J tion.
An important object of the invention is to construct the side rails of automotive frames from very light gauge tubular stock; the invention also comprehending the provision of kick-up portions in the rails of less diameter than the mid-section but possessing greater wall. thickmess tobetter withstand loads and stresses inci-' dent to its use.

A further object is to provide spring hanger supports on the extended ends of certain cross members.
A still further object is to provide a pressed metal cross member of box section with means providing box section joints with the side rails.
Other objects and advantages'of the invention will become apparent during the course of the following description.

Referring now to the drawing for details, the numeral M designates a length of tubular stock appropriate for the formation of a complete side rail I5 of an automotive vehicle. This stock-- is preferably very light gauge such as stock,
due" in a'meas'ure to the torsion resisting ability of a tubular section over the channel section and the additionalstrength which isbuilt into the'ra ils'with my herein disclosed method of manufacture and type of cross members. The stock for the side rails is preferably circular in cross section as shown in- Fig. 6 and is preferably, but not necessarily, obtained from a continuous method of producing welded tubing from flat stock rolled up into tubular formation and then welded along a single longitudinally extending seam 'ltgas disclosed in my 'co-pending applications. 'However, it is to be understood that any klnd of'tubing, seamless or. otherwise, may be employed in the method and the sections of the stock may be circular, oval, rectangular. or otherwise. In the present instance, I' will describe the method using the stock which is circular in cross sectio'ni v After the stock has been cut to the required length, one end ll, constituting the forward end of the side rail is reduced in diameter and approximate locality of the dash line or at least to a point'where the rear hangers I8 of the front springs l9 are securedto the rail. The taper at this .end is gradually back into, the original diameter of the stock and is accomplished'by running the end into a swaging machine or any other-suitable apparatus which will give the end 'I'I the-contour illustrated and at the same time substantially increase the wall thickness of the tapered end as indicated. by the dotted line 20. This tapering and reduction of the ends of the tubing is sufficiently extensive to -take in the entire "front kick-up or oifset portion 2!.
f The other or rear end 22 of the stock'is similarlyreduced but to a great-i! degree from its tapered from its free end to a point back to the free end to a point in proximity to the front hanger 23 of the rear spring 24 so that the wall thickness of a considerable rear end portion of the rail is materially increased as indicated in dotted lines 25. The diameterof the rear end 22 of the side rail is reduced over a greater distance or length than the forward end, to obtain greater clearance for the rear axle without the necessity of too severe a kick-up or oifset portion in the rail. This also provides for the introduction of greater wall thickness at the rear kick-up than at the forward one, but of course the wall thickness of both oifset or kick-up portions can be made uniform or proportioned as desired. It will be noted that the taper of the major portion of the rear end 22 is more gradual than the forward end from the free end just beyond the kick-up from which point the taper increases to cause the rear end to more gradually merge into the--mid-section 28 of the rail.
After the ends of. the rail have been reduced.
in diameter and increased in wall thickness as shown in 2, they are run into suitable tube bending equipment to provide the forward and rear ends with the offset or kick-up portions 2| and 26. be appreciated that the stock remains circular or approximately so in cross section. Of course if the original stock is other than circular in cross section to start with, it will possess the same cross section when it reaches the conditionas shown in Fig. 4 in the operations, with of course, the ends reduced and their wall thickness increased. Obviously, if the stock is originally box or rectangular in cross section with substantiallyflat side walls .29, as shown in Fig. 7, the side rail requires no further for.
ing operation and at this stage is ready for the assembly of the cross members.
-However, when the original stock is circular in cross section, it is desirable to flatten the rail shownin 4 to bring it to closed box section for additional strength as shown in Fig. 7 and this may be accomplished by flattening the entire length of the rail by subjecting the rail shown in Fig. 4 to the action of suitably contoured flattening dies in the well known form of press or by subjecting the rail to inward pressure on all sides between suitably contoured pressure rolls.
Two rails thus formed are connected in the desired relation by tubular cross members as shown in Fig. 1G. The front cross member is formed by two oppositely facing channel members 30, with the longitudinal edges of the flanges welded together as at iii. The ends 32 of the channel members adjacent the side rails diverge outwardly and are provided with flanges 33 which are welded in any desired manner to the inner web portion 34 of the side rails. Triangular gussets 43 are posi tioned in between the diverging ends of the channel members at the top and bottom thereof in the planes of the top and bottom flanges, to be welded to the edges of the flanges and to the side rails to form the ends of the cross member into closed box cross section. In case this type of cross member is incorporated in a frame having the usual channel section side rails, the edges of the gussets 43 are welded to the edges of the inwardly extending.
flanges of the side rails.
The secondand third cross members 35 are tubes and their opposite ends are extended through registering openings provided in the spaced web portions 34 and 36 of the side rail; The inner web 34 is secured'to the tubular cross During the foregoing steps, it will member 35 by a weld 3'1 extending circumferentially around the entire circumference of the tube, while the outer end of the tube projects a distance beyond the outer web 38 and in the case of the third cross member, is melted down and fused to the outer web 35 by any suitable welding equipment. If desired, the webs of the rails may be provided with inwardly or outwardly projecting annular flanges surrounding the opening through which the ends of the cross'member extend and the ends of these flanges may be fused to the ends of thetubular cross member. The second tubular cross member 35 may have its two ends 35 extended beyond the outer websof the side rails and have spring hangers 44 secured thereto as shown in Fig. 11.
A fourth cross member 38 is secured to the two rails just in front of the rear kick-ups 26 and adjacent to where the latter merge into the midsection of the rails. This cross member 38 is also preferably of tubular form and its ends 38 may be extended outwardly. beyond the outer webs .of the rails to have spring hangers mounted thereon. This cross member on the third one 35 may be provided with an integral flange 39 at each end for abutment with the inner web 34 of each side rail. This flange is provided with a series of ciroumferentially extending keyhole shaped slots 40 whereby they can be are welded to the inner web of the rail. It will be noted that the slots 40 are not of uniform width throughout but terminate at one end in an enlarged end portion 43 whereby the flame of the welding torch can be entered to properly fuse the metal of the web simultaneously with the edges of the slots, after which the flame of the welding torch can be moved into the narrower portion of the slot to properly fuse the balance thereof to the web portion. An opening 44 substantially concentric with each enlarged end 43 of each slot is provided in the underlying web 3 to facilitate simultaneous fusion of the members to be joined, and some of the fused metal will be deposited in the opening 44 to additionally lock the parts together.
A fifth tubular or elliptical cross section cross member 4! connects the rails immediately behind thekick-up 26, or if desired, may be connected to the mid-portions of the kick-ups, with a sixth tubular or elliptical cross section cross member 42 tying the extreme rear ends of the rails together. While various methods of attaching the cross members to the side rails have been specified in connection with certain cross members, it will be understood that any of the modes of attachment h rein disclosed may be employed for attaching any of the cross members to the side rails. The cross members may also be of any cross section or shape to provide clearances for other parts of the vehicle or for any other purpose. It will also be noted that the longitudinal weld E6 in the stock isshown disposed in the top of the rail, but it may of course be arranged so that it is arranged at the bottom of the rail, or in either side web thereof.
It is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the appended claims.
