HERMAN 'URBAHNS, OF HAMMOND, INDIANA..

CAR-SEAL.

Specification of Letters Patent.

Patented 15139134,- 1916.

Application led November 22, 1913, Serial No. 802,453.` Renewed September` 20, 1915. Serial No. 51,699.

To all whom t may concern Be it known that I, HERMAN URBAHNs, citizen of the United States, residing` at Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Car-Seals, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in car seals and has for its principal object to provide a device of this character which is simple in construction, Vdurable and reliable in operation 4and may be easily and quickly manipulated and applied to apar door to prevent the undetected opening thereof.

My invention has for another object to provide a device of this character which will obviate the necessity of employing a sealing iron or other tool to effect the application thereof.

Y The invention has for another and very important object the provision of a car seal which is constructed from a single piece of material thereby conducing toV a low cost of manufacture and resulting in a construction of a highly desirable and superior nature. Y

lVith the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in

which- Figure 1 is a plan view of the seal in blank or as it is cut from the metal sheet. Fig. 2 is a perspective view illustrating the arrangement of the several structural features of the metal strip, at a point in the folding of the strip for its application to a door or other part to be sealed, one of the flanges on the edge of the strip being partially broken away. Fig. 3 is a similar view, the seal being completely folded and shown applied to a car door;V Fig. 4 is an enlarged longitudinal section taken on the line 4-1 of Fig. 3; Fig. 5 is a section taken on the line 5 5 of Fig. 4.

Referring in detail to the drawing, 5

designates the body strip of the seal which is cut from a sheet of tin or other metal.

This metal strip adjacent one vof its ends is wider than the remaining portion of the strip, thereby producing anges 6 upon its longtudinal edges. The adjacent end-Tof the strip constitutes a tongue 7. The widened portion 0f the strip has centrally formed therein a vdepression or recess 8 which is produced by means of a suitable die. The body 5 of the strip adjacent to the flanges 6 is further formed with a protuberance or'projection 9 projecting from one face thereof in an oppo-site direction to the bulged or outwardly :struck portion of the strip which forms the socket or recess S. A longitudinally extending tongue l() is cut from the strip at its other end, one end of esV said tongue remaining integrally vattached i to the strip while the point of said tongue projects inwardly. This tongue normally lies .in the plane of the body 5.

In the application of my invention to a car door, the metal strip 5 is first bent upon itself at the inner ends of the flanges 6V thereon so as to dispose the recess 8 in opposed relation to the spur or projection 9 on the strip. The flanges 6 onthe edges of saidv strip are now bent over upon the body of the strip as shown in Fig. 5 and crimped thereon I to retain the end portion of the strip which is provided with the tongue 7 and recess 8 in its folded position with relation to the l' body of the strip.V The tongue 7 is now bent at its point of connection to the widened portionV of the strip so that the same is disposed between said spur or projection and the recess. The body portion 5 of the strip is bent Vandthe end thereof which is pro vided with the tongue 10 extended through the staple on the door. This end of the strip is now inserted between the tongue 7 and the projection 9, and pressure is brought to bear upon the widened portion of the strip so that the projection 9 will act to force the tongue l0 out of the plane of the body of said strip. When the attempt is made to withdraw the end of the strip from between the flanged portion thereof and the body lof the strip, the tongue 10 will move over they end of the tongue 7 so that said latter tongueV will force the tongue l0 outwardly from the body of the strip and into the depression or recess 8. This tongue will effectually prevent the withdrawal of the end of the metal strip, by its interlocking engagement with the tongue 7.

nection with the acompanying drawing, it is l From the above description taken in contively narrow; longitudinally extending :s eat 1 Aor recess, said strip also having a proJection formed thereon inwardly of and inl spaced 35 believed that the construction and manner of operation of my invention will be clearly andf'ully understood.

As the device may be cut or stamped out of a single sheet of metal, it Will be obvious that the same can be produced at very small It can also be very manufacturing cost.

relation tothe inner endsof said flanges, a: tongue cut from said strip ad]acent its other end and normally lying inthe planeet the body of the strip, said flanged portion lof easily and quickly manipulated and applied to a cai' door or other part which it is desired to seal. The locking action is automatic Vand the device as a Whole highlyserviceable and convenient in practical use;

upon. the strip body to dispose said recess,y Y in opposed relation: to said projection, said .Y liistlnamed tongue being folded inwardly longitudinally of the stripto` extend over one end of `said recess,- saidrzflanges beingf 45 the strip being adapted to be folded Vover 40" lVhile l have above described `the preferred form and construction of thescveral features of myinvention, it will be understood that the device in these particulars is susceptibleY of considerable modification and I therefore reserve the nrivilege of resortincr e, b

The herein described car seal formed from a a ductile metal strip saidstrip being provided adjacent onek of its ends and on its longitudinal edges with flanges, the end of Copies of this patent may bciobtanedlfor adapted to be bent around the edges of the strip to. retain; the recessed portion thereof in folded. relation to the striplbody, and the other end of said strip being adapted for insertion between said folded tongue andthe 59 projection on `the strip body whereby '.the fr second named tongue is forced out `oit the -f plane of the strip and intosaid recess to dis-V pose the same in position for interlocking.`

engagement with said first named tongue c55 upon anv attempt =to `Withdravvf the lastlre-l ferred to end ofl the strip.

In testimony whereof I :hereunto aiiix ymy signature in the presence of two Witnesses.
