METHOD OF CONSTRUCTING AND STRAIGHTENING VEHICLE BODIES Filed Sept. 21, 1929 INVENTOR.

Is c'a ore Dar 2 BY A TTORNEY Patented Jan. 6, 1931 UNITED'STATES PATENT OFFICE ISIDORE DANZIG, OF BROOKLYN, NEW YORK METHOD OF CONSTRUCTIHG AND STRAIGHTENING VEHICLE BODIES Application filed September 21, 1929. Serial No. 894,296.

This invention relates to motor vehicles and has more particular reference to a novel construction thereof, a method for such construction, and-a method for repair due to bending of parts of said construction during slight collisions and the like.

In congested city traflic and in small passages into private garages, it is extremely diflicult to escape denting the fenders on a car. The car is in continual danger and sooner or later denting is bound to occur.

0 owner of a new car prizes it highly and tries his best to keep it in good condition. After several dents in the fenders and the body which cannot be perfectly repaired, it has a moral effect upon the owner and he tends to neglect the upkeep thereof. Accordingly, it is proposed to construct a car which willnot readily show dents and which can easily be repaired and in repaired condition be unrecognizable that any damage was pre viously sustained. g i

It is also proposed to construct a car which the owner may repair himself as far as dents and slight bending of the fenders or the body iscQncerned. According to present day car construction it is necessary to have a skilled body builder repair the car the repairing is not perfect easily recognize the places viously, people can repair bending and dents and in repaired condition compete with the repairing of any of the present day cars by skilled body. builders.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to" the following description and accompanying drawings, and to the appended claims inwhich the various novel features of the invention are more particularly set forth. I

In the accompanying drawing forming a material part of this disclosure nd anyone can and even then of repair. Obthere is a great saving if unskilled Fig. 1 is a perspective view of acar constructed according to this arrangement.

Fig. 2 is an enlarged fragmentary sectional view taken on theline 2-2 of Fig. 1.

Fig. 3 is a fragmentary elevational view ipoking in the direction of the line 33 of Fig. 4 is a fragmentary enlarged sectional view as though taken on the line H of Fig. 1 but disclosing another embodiment of the invention.

The reference numeral 10 indicates generally a car of any design or construction and having a body 11, a hood 12, front fenders 13 with spare tire depressions 14, and rear fenders 15. The body and the fenders have a plurality of irregular indentations 16 upon its surfaces simulating hammered metal. The design may be uniform as illustrated in F ig. 3 or may be haphazard.

The method of constructing the car consists of forming the surfaces of the body and fenders irregular for simulating hammered metal, preferably with each of the hammered blows disposed inwards or concaved. This 7 method may be carried out by constructing the car with materials initially provided with the 1 irregularities for simulating the hammered blows, which is the cheapest way of obtaining the construction, though, of 7 course, a car may be formed with the hammer blow-- structure after it has been completely made. If made according to the former a rrangement the sheets may be stamped 1n presses and thus form the irregularities.

A car constructed according to this invention may receive bends or dents in its body or fender. The method of repair consists 1D first bending out the dented or bent portions further than the correct positions and then 35 with a hammer, striking the surfaces and gradually bending the surfaces back Into their original positions. Thus the new concaved depressions formed by the hammer blows in the method of reconstruction comg mingle and mix with the hammer dents initially in the car and when the repair is co1 npleted it is practically impossible to recognize that such repair has been done. If the design initially was uniform traces may be left of the repair work but the irregular surface of the car blends with the repairing surface in such a manner that recognition is impossible to the eye of the ordinary observer.

The invention may be modified so that the car construction is composed with its body and fenders having irregular surfaces simulating hammered metal with the hammer blows convexed or projecting outwards. When thus constructed it is necessary to re pair the dents or bends in the car by hammering from the inside outwards or in other words so that the new hammer depressions correspond with those initially in the car.

InFig. 4, a modified form has been illus trated in which the hammer blows are concaved and convexed in the one car construction and arranged for ease in repairing. Preferably the edges of the fenders should be formed with concaved hammer blow depressions as indicated by reference numeral 17 and the other parts of the fenders and the bodyshould be formed with convexed hammer blow portions 18. During the denting of the body and the fender portions, the denting occurs in the great majority of cases inwards and it is necessary to hammer the parts outwards for returning them into their initial condition. For this reason the convexed hammer blow portions on the body and the greater portions of the fenders are desirable. It is generally known that the edges of the fenders very often are drawn outwards in collisions and for this reason the concaved hammer blow depressed portions 17 are advantageous along the ed es in that the drawn out portions may be mmered inwards for forming the correct shape of the bent parts.

While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. In a vehicle construction, a body having a hood portion and fenders with an outer metallic surface formed irre ularly and simulating hammered metal so t at when accidentally deformed or bent may be hammered back into form so that the repair is unnoticeable, the hammer-blow irregularities on the edges of the fenders being concaved and the irregularities on the other portions convexed.

- 2. A method of straightening bent por- In testimony whereof I have aflixed my signature.
