E. IVINS BUMPER BAR FOR AUTOMOBILES a Filed March' 5, 925
Fatented June 9, 1925.,
PATENT OFFICE.
ELLWGOCD IVINS, OF PHILADELPHIA, PENN SYLVANIA.
BUMPEE BAR FOB AUTOMOBILES.
Application filed March 3, 1925.
To all 'whom it may cmuar-n:
Be it known that I, ELLWOOD IvINs, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Tinprovements in Bumper Bars 'or Automobiles, of which the following is a specification.
The object of my invention is to improve the Construction ot' bui'nper bars, which are used on automebiles and like vehicles, so that the polished surface of the bar will not become dis-figured.
The present method of making bumper bars is to make the bars of iron or steel tubes and to' electro-plat-e the bars with nickle.
T he objection to this method of manufac ture is that the thin plating of nickel becomes detached from the bar, exposing the iron or steel base, When the bar comes in violent contact with an object, or is scratched, or otherwise injured, making the bar unsightly.
In the accoinpanyng drawings:
Fig. l is a pers pective view of my i1nproved bumper bar; v
Fig. 2 s a seotional View of one end of the bar; and
Fig. 3 is a transverse sectional View on the line 3-3, Fig. 2.
The bar l is made of a hea` y, drawn seamless tube of iron or steel, of any desired diameter. Over the bar l is drawn a seamless tube 2 of nickel alloy. The two tubes Serial No. 12,925.
are closely associated, as the drawing action makes the nickel alloy tube adhere to the iron, or steel tube. The nickel alloy tube is heaver than the plating heretofore used and does not crack, nor does it expose the iron base, if scra-tched. If the nickel alloy tube is cut so as to expose the base, the nickel alloy tube is in no Way atected.
The tube can be open at each end, or it can be provided with an ordinary cap, if desired, which is ornamental in any suitable manner.
The bumper brackets 4: can be of any form desired. Then they are elamped to the bar, as in Fg. 2, they engage the nickel -tubular shell and can be clanped tightly thereon without damagng the shell, as the nickel yields under pressure, and does not crack to expose the base metal.
I claim:
1. A bumper bar for other, vehicles, consisting or steel enclosed within nickel alloy. i
2. A bumper bar for automobiles, and other vehicles, consisting of a drawn steel tube, over which is drawn a tube of nickel alloy.
3. A bumper bar for automobiles, and other vehicles, consisting of a drawn, seamless steel tube, enclosed within a drawn,
seamless tube of nickel alloy.
