Application led May 12,
The invention relates to vehicle hubs and similar hollow articles, and facilitates theirproduction at a comparatively loW cost in labor and material, and has other advantages referred to in detail hereinafter. The accompanyiug drawings illustrate embodiments of the invention.
Figs. 1 and 2 are respectively a side and an end view of a segmental formed blank;
Figs. 3 and 4 are respectively a longitudinal section and an end Viewr of two formed blanks assembled for Welding;
Figs. 5 and 6' are respectively' a Side elevation and a cross section on the line 6-6 of Fig. 5, of the Welded product;
Fig. 7 is a similar section of the. finished product;
Figs. 8 and 9 are respectively an end and a side view of the rolled bar stock from which the segments are made;
Fig. 10 is a side elevation of the roughly lini shed product;
Fig. 11 is a similar view of a dierent design;
Fig. 12 is a longitudinal half section showing the product ready for use. l
The hub (referring first to Fig. 10) has cylindrical portions 1 and 2 of different diameters with a Wide annular Hange 3 to which if the wheel is bolted or otherwise secured and generally has one or more internal annular shoulders 4 and ribs 5. In the design'ot Fi 11 there are cylindrical portions 6 and an outer annular flange 8 and ribs 9 and 10; this being of the same character as the hub of Fig. 11 and differing only indesign.
The forged Welded product described is turned to the shape shown in full lines, Fig. 12; the dotted lines corres ending to Fig. 10. The outer face of the smal er tube 1 is turned as at 1a and reduced on the end as at 1b to receive the wheel and fastening devices, and the flange 3 is turned on the flat face 3a for attachment to the Wheel. The insides of the tubes are turned as at 1c and 2a and the ends are squared off at. 1d and 2". It is not neces- .f'ary in all cases to do all of the turning described. One of the advantages of this invention is that the hub may be shaped in some .no cases to eliminate part of the machine operations and in all cases to reduce the amount of machine Work.
The hub is produced by forging separate Segments and Welding these together. in making the hub of Fig. 10, the segments are 1926. serial No. 108,443.
pressed into the left end of the hub.
By the shoulders 14 and 15 the thickness of the tubular Wallis maintained approximately constant throughout the length. The segmentv is substantially semi-circular With an extension 17 on each of the longitudinal edges to be taken up in the Welding. TWO such' forgings are assembled between positive and negative electrodes 18 and 19 shaped to iit them closely and are brought together With their extended edges in contact and Welded preferably by the method of the Murray Reissue Patent No. 15,466 of October 10, 1922 in which While the parts are pressed together a current of extremely high density is passed across the joint for a very brief period of time. As a result the surplus stock 17 is extruded sidevvise forming fins 2O as in Figs. 5 and 6. The extruded metal or flash is removed by cutting or grinding it off, leaving the finished section as in Fig. 7 and the external appearance as in Fig. 10. The rough Welded hub is then turned down as in Fig. 12 or otherwise shaped to form the accurate cylindri'cal and fiat surfaces required for attachment of the Wheel to the outside and of the shaft and bearing to the inside. 1
The segments can be economicallyproduced from rolled steelbar stock, the cross section of which corresponds approximately to the longitudinal section of the hub. For example, for segments like Fig. 1 We may use the bar stock of Figs. 8 and 9 having flat portions 21 and 22 in dierent planes with a longitudinal flange 23 on one side and with shoulders 24 and 25 and a longitudinal ange 26 on the other side. Starting With such bar stock the forging operations are reduced anda saving in material is eifected compared with the ordinary forging from plain blanks.
For making the hub Fig. 11, the process Would be substantially' the same, starting With a piece of rolled bar stock correspon ding approximately With the longitudinal section of the hub, forging the segments, Welding and trimming off the flash and finally turning to exact dimensions.
`lBy this method, the parts may be produced of a strength equal to or greater than by ordinary methods of manufacture and at the elsewhere, giving in effect a one-piece forging 'which is cheaper and capable of greater variation in design than any forgings heretofore available.
The original stock and the segments forged therefrom should be of proper dimensions to allow surplus stock entirely over the faces which are to be turned down in the final operation. And this turning operation may be supplemented or substituted by grinding, and other known methods of working to exact dimensions. Various other articles'of tubular 'shape with annular flanges and shoulders may be made by the same method, providing a surplus of metal wherever the dimensions are to be accurately produced by turning or similar operations.
Various modifications may be made by those skilled in the art without departing from the invention as defined in the following claims.
What I claim is: 1
1. In the production of vehicle hubs or similar hollow articles the method which consists in cutting blanks from a rolled bar having flat portions extending lengthwise in different planes and a longitudinal flange on one side, forging such blanks into segments having cylindrical ends of different diameters formed from the fiat portions of the blank and an outer annular flange formed from the' longitudinal flange of the blank, welding such segments together along their longitudinal edges with a resistance weld, trimming off the flash produced at the joints and turning the rough product thus formed to the exact dimensions desired. l
2. In the production of vehicle hubs or similar hollow articles the method which consists i cutting blanks from a rolled bar having fla-t portions extending lengthwise in different planes and a longitudinal flange on one side, forging such blanks into segments having cylindrical ends of different diameters formed from the flat portions of the blank and an outer annular flange formed from the longitudinal fiange of the blank and welding such segments together along their longitudinal edges. I
3. In the production of vehicle hubs'or similar hollow articles the method which consist-s in cutting blanks from a rolled bar having flat portions 21 and 22 extending lengthwise in different planes and a longitudinal flange 23 on one side at the junction of said flat portions, forging such blanks into segments having cylindrical ends of different diameters formed from the flat portions of the blank and an outer annular flange at the junction of said cylindrical portions formed from the longitudinal flange of the blank and welding such segments together along their longitudinal edges.
In witness whereof, I have hereunto signed my name.
