GEORGE J. THUST, OF DETROIT, MICEIGAN, ASSIGNOR TO DETROIT SEAMLESS STEEL TUBES COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

VEHICLE-POLE.

Specification of Letters Patent.

Application filed September 11, 1968.

Patented May 10, 1910.

Serial No. 452,607.

To all whom it may concern:

Be it known that I, Gnonon J. THUsT, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Ve hicle-Poles, of which the following is a specification, reference being had therein to the accompanying drawings.

It is the object of the invention to obtain a metallic construction of vehicle pole which is strong, graceful in appearance, and comparatively inexpensive to manufacture.

To this end the invention consists in the construction as hereinafter set forth.

In the drawingsFigure 1 is a perspective view of the pole; Fig. 2 is a longitudinal section thereof; and Fig. 3 is a cross section.

In my improved construction both the pole proper and the cross bar to which it is attached are formed from metallic tubes either seamed or seamless, but without crevice. The construction is, therefore, much stronger than one formed up from sheet metal. Furthermore, the tubes are tapered which both adds to the appearance and gives a better distribution of the metal for strength. The tapering of the tubes is accomplished by a swaging operation with the result that the walls of the tubes are thicker in the portions of reduced external diameter than in the larger portions which also adds an element of strength.

In detail, A is the tube constituting the pole proper, and which is tapered toward its outer end from the point at or near the attachment of the braces. The portion of the tube B in rear of this point is tapered in the opposite direction, and is also bent into a curved form. The inner end of this portion B is united with the cross bar C, which latter is formed of a metallic tube tapered oppositely from center to ends. The tube members are united to each other preferably by a fitting D which has a shank portion D engaging the end of the member B and an annular portion D sleeved over the cross bar C. The fitting is preferably secured by being shrunk upon the bar C having a similar joint formed between its shank D and the tube 13. h

At the point of exchange and taper of the pole member A is attached a fitting E which also is preferably shrunk upon the pole and which is provided with oppositely-extending ears E E These ears are apertured for engaging the ends of the brace members F which extend to the outer ends of the cross bar C and preferably beyond the latter to form the draft connections. The braces F may be riveted or otherwise secured to the cross bar and at the end engage the ears E and E which are preferably threaded to engage clamping nuts G. The fitting E is also preferably provided with a bearing E for the whiiiletree apertured to receive the pivot belt of the latter. There is further a bracket member H which is riveted or otherwise secured to the portion B and extends above the bearing E which is apertured in alinement therewith.

I are ears attached to the cross bar C forming securing means for the doubletree.

What I claim as my invention is:

1. A vehicle pole, comprising a pole proper formed of a single-piece seamlessdrawn tube having a tapering curved shank, a curved cross bar tapering toward its opposite ends, a fitting centrally positioned and shrunk upon said cross bar and engaging said curved shank, braces extending from the end of said cross bar to said pole member, and a fitting shrunk upon said pole member forming an anchor for the braces and a bearing for the whifiletree.

2. A vehicle pole, comprising a pole proper formed of a single-piece seamlessdrawn tube tapering toward its opposite ends and having a portion thereof curved to form a shank, a curved cross bar tapering toward its opposite ends and having the latter sealed, a fitting shrunk upon said cross bar and engaging said curved shank, braces eX- tending from the end of said cross bar to said pole member, and a fitting shrunk upon said pole member forming an anchor for the braces, and a bearing for the whiihetree, the

.walls of the pole and cross bar increasing in thickness toward the tapering ends of said members.

3. A vehicle pole, comprising a tubular member forming a pole proper and having a portion thereof curved to form a shank, a curved cross bar tapering toward its opposite ends, a fitting shrunk upon said cross bar provided with a laterally-projecting lug positioned Within the end of the tube of the shank, the latter being secured to the lug by shrinking, braces extending from the end of said cross bar to said pole member, and a fitting shrunk upon said pole member forming a bearing for the whiffietree and having laterally projecting lugs forming anchors for the braces, the Walls of the pole and cross bar increasing in thickness toward the ends of said members. 10

In testimony whereof I affix my signature in presence of two Witnesses.
