CAR-SEAL.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed August 17, 1915. Serial No. 45,985.

To all whom it may concern:

Be it known that I, WILLIAM J. DORSAM, a citizen of the United States, residing at La Fayette, in the county of Tippecanoe and State of Indiana, have invented new and useful Improvements in Car'Seals, of which the following is a specification.

This invention relates to car door seals, and more particularly to that class of seals which are constructed of but a single piece of material.

The primary object of the invention is to provide a seal for car doors which may be stamped from a piece of sheet metal at a single operation and which may be quickly and easily arranged for application to a car door.

A further object of the invention is to provide a deviceof this character which is extremely simple in construction, cheap of manufacture, which may with facility be applied to a car door, and which when once applied insures against unauthorized opening of the car door without detection.

With these objects in view together with others which will appear as the description proceeds, the invention resides in the novel combination and arrangement of parts, all as will be described more fully hereinafter and particularly pointed out in the claim.

The invention will be betterunderstood by reference to the accompanying drawings, wherein Figure 1 is a plan view of the blank from which the improved seal is formed; Fig. 2, is side elevation of the blank after having been shaped for assembling; Fig. 3 is a perspective view of the seal in the process of forming; Fig. 4 is an enlarged fragmentary longitudinal section taken through the im-.

roved seal showing the same fully assemfiled, and Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 4.

In the drawings 6 refers generally to the strap from which the improved seal is formed and which may be constructed of any preferred material, however, thin tin is found to be particularly adapted to this use. The strap is so stamped or cut as to provide a widened portion 7 at one end, the said widened portion being composed of sections 8 and 9 the latter being a trifle wider than the former, and the extreme endof this portion of the strap is provided with an extension 10 of a reduced width and approximately equaling that of the strap proper.

aperture, preferably The extension 10 is provided with a pair of spaced parallel cuts or incisions ext-ending inwardly a short distance from the extreme end of the strap and the metal between the incisions is bent angularly to provide a spring tongue 12. The section 8 of the strap is provided as at 13 with a depression of substantially the same width as the strap 6 and increasin in depth from the inner to the outer end of the section 8. The opposite end of the strap is provided as at 14: with an of rectangular shape, and being of a width substantially equal to that of the tongue 12.

In shaping the strap thus formed to provide an efiicient seal the outwardly projecting lateral edges of the section 9 are bent at right angles to the body of the strap to provide flanges 15. These portions are bent on a line with the lateral edges of the section 8. The extension 10 is bent adjacent its juncture with the section 9, back to lie fiat upon the latter, and its ends are bent outwardly at right angles to the strap to form stops or abutments 16. The entire section 9 is then bent over upon the section 8, thus forming with the latter and the depression 13 a housing open at its inner end only such distance as will permit of a proper insertion of the apertured end of the strap 6. The flanges 15 are bent over or crimped upon the adjacent edges of the section 8 to hold the housing in closed position.

With the improved seal thus arranged it is obvious that upon insertion of the strap 6 through the hasp or staple of a car door and the apertured end of the strap into the housing provided at the opposite end of the strap, the door will be insured against entry without detection. Upon insertion of the apertured end of the strap within the housing the tongue 12 will snap or spring within the aperture 14, and upon slight withdrawal movement of the strap, the end by reason of the resiliency of the said tongue, will be forced inwardly to seat itself between the tongue 12 and the abutments or stop 16 whereupon movement of the strap end will be held positively against movement in either inward or outward direction. The depression 13 being of substantially the same width as the strap end will prevent lateral movement of the apertured end within the housing, as the said apertured end will be held seated or secured within the said depression.

By crimping the lateral edges of the sections 8 and 9 together it is apparent that any attempt to pry open the housing to eflect a release of the strap end will break the thin metal constituting the flanges 15, thus causing a mutilation of the seal.

I claim A car seal constructed of a metal strap having an apertured end and being widened adjacent its second end and provided with an extension beyond the said widened portion, said strap, at the widened portion thereof being bent upon itself to provide a housing having an opening at its inner end only, and the outer Wall of the housing being provided with a depression which gradually increases in depth from the said open end, the extension at the widened end of the strap being bent in the housing, the said extension being provided with parallel incisions and the metal between the incisions being bent angularly to provide a spring tongue, the ends of said extension in the housing being arranged angularly to provide stops, and the apertured end of the strap adapted to be inserted in the housing and to be guided by the outer wall of the depression to have its aperture receive the tongue and its end contacted by the stops, as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
