HOUSING AND METHOD OF MAKING SAME.
Application filed November 30, 1921.
To all whom it may concem Be it known that we, THOMAS E..MURRAY and THOMAS E. MURRAY, Jr.,'citizens,.of'the United States, residing in Brooklyn, Kings County, and State of New York, have 'invented certain new and useful Improvements in theAxle Housings and Methods of Making Same, of which the following is a specification.
Our invention aims to provide certain improvements in the construction and method of production of axle housings andsimilar structures such as are commonly used for the rear axles of automobiles, by which improvement certain economies are effected and certain other advantages referred to hereinafter are secured.
The accompanying drawings illustrate embodiments of the invention.
Fig. l is an elevation of a complete'housin? c ig. 2 is a cross-section on the line 2-2 on an enlarged scale; Fig. 3 is a cross-section on the. line 33 also on an enlarged .scale;
Figs. 4 and 5 are perspective viewsillustrating opposite faces of a detail;
Fig. 6 is a section similar to Fig. 3, illus-- 'trating an alternative construction;
Fig. 7 is a perspective view of a detail of this constructlon; a
Fig. 8 is a perspective view of part of a rinlg, illustrating a third alternative;
. 9 is a development of a, blank used in forming a segmentof the housing.
Referring to the embodiment of the invention illustrated, the housing comprises a central enlargement I of annular shape with a transverse opening through which the gearing within is made accessible; tubular portions 2 for the axles being extended from the sides of the enlargement.
In making the housing, blanks are used of sheet metal of the form shown in full lines-in Fig. 9. Such a blank is bent up transversely to form the outer ring 3 and flanges 4' of the enlargement and the semicircular segments of the tubular extensions;
and is bent longitudinally to ive the shape shown in Fig. 1. In Fig. 9 t e wider central portion 5 of the blank forms the enlargement of the housing and the narrower ortions 6 form the tubular extensions. Iwo such segments are then placed edge to edge and united along their meeting edges, preferably by welding. In order that the Serial No. 518,743.
the outer face of the adjacent portions of the structure. Such a filler may be provided in a number of different .ways. According to Figs. 3, 4 and 5 the ring 10 is formed of two halves 10 and 10*, the ends of which are cut obliquely and overlapped one on the other to provide a substantially triangular boss 12 which fills the space between the diverging edges of the blanks.
vThe two half rings may be spot welded or otherwise fastened at their overlapping ends, or they may be assembled without preliminary. fastening. When the parts are assembled and the'edges 7 welds together they may be welded also to the edges of the part 12 and the two half rings 10 and 10 welded to each other.
In the construction shown in Figs. 6 and 7 the rings 10 are continuous and a separate triangular filler 12 is welded thereon and serves to fill the s ace between the diverging edges 7 when t e parts are assembled. 'Or the filler 12 may be set in place and united to the segments or to the ring in other ways and at other stages of the operation. 0
According to Fig. 8 the nu is formed each of which will constitute half of the filler. When two such half rings are assembled the contacting end portions 12 thereof will constitute a complete filler. The rings and segments are united in any desired order. They may be welded for example to the edges of the formed segments or may be spot welded to the flange of the enlarged portion of the housing.
\Vith housings made according to this invention there is a saving of approximately thirty percent in the quantity of steel used. The rings may be made of-scrap steel cut -in straight strips and bent up in the plane of the metal. Also this construction produces a stronger housing by tying the ring to the outer shell through the shoulders formed within the divergent edges.
Preferably the parts are welded together as described although it is essential only that the straight edges of the segments be united. It is also within our invention to unite such edges by various other means than welding.
The invention is applicable not only to axle housings, but to various other hollow structure and particularly to similar structures comprising a tubular portion merging into an enlarged portion with a transverse opening. It is not essential in all cases that the space between the diverging edges be filled. The ring or equivalent member may be of suflicient strength, or the segments themselves may be of sufiicient strength to serve the intended purpose of the structure without the filling in of this space.
Or the space may be filled by the introduction of molten metal. For example, the ordinary arc welding machine may be employed to deposit the desired quantity of metal to fill this space and at the same time to weld the parts together at this point.
In a co-pending application of Thomas E. Murray. Jr., (No. 517,056 filed November 22, 1921) there is described a method of stamping out blanks for the segments used in making axle housings or the like, according to which the blanks are stamped out minus certain projections (the lateral projections 9 or the comparatively narrow end projections) and such projections are made of separate stampings welded to the blanks before bendin them into segments. The present invention includes the same step of stamping out incomplete blanks andthe addition of the necessary part or parts after the bending operation: either to thebent up segments before welding or to the welded structure.
Though we have described with great particularity of detail certain embodiments of our invention, yet it is not to be understood that the invention is restricted to the particular embodiments disclosed. Various modifications thereof, in. detail and in the arrangement of the parts may be made by those skilled in the art without departure from the invention as defined in the followin claims.
Vhat we claim is- 1. An axle housing or the like comprising an enlargement with inward flanges and with a tubular extension from the side said housing being formed of longitudinal segments the edges of which are united along the tubular extension but diverge where the latter merges into said flanges.
2.
