SEAL.

Specification of Letters Patent.

Patented June 20, 1916.

Application filed April 13, 1915. Serial No. 21,012.

To all whom t may concern l:

' Be it known that I, RAYMOND H. JUNE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented an Improvement in"Seals, of which the following is a specification.

This invention relates to seals and more particularly a seal adapted for luse on the doors of railroad rolling stock, said seal being of that type wherein a metal strip'is y passed through the staple of the door and strip shown in locked position.

secured at its ends so that the same would have to be broken in order to gain access to the car, thereby indicating whether or not the car has been entered any time subsequent to the sealing of the door.

The object of my invention is to provide simplified and more efficient construction for rigidly interlocking the ends of the seal andv preventing separation thereof after they have once been brought together, and

to provide improved means for preventing insertion of tools or appliances to thereby prevent picking of the lock. 4

vThe inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, `for the purpose of illustrating the invention, is shown in the accompanying drawing, in which- Figure 1 is a perspective view of the ends of the strip constructed in accordance with the invention. Fig. 2 is a vertical longitudinal sectional view of the ends of the Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 is a view similar to Fig. 2 showing the parts previous to being locked. Fig. 5 is a top plan view of the strip before being bent into the form of a loop to lock the ends together. Fig. 6 is a plan view in blank of the strip, the dotted lines showing the manner of folding the same. Fig. 7 is a top plan view of the housing partly broken away and shown in section.

Referring more particularly to the accompanying drawing, in which like reference characters designate similar parts, the numeral 10 indicates the body portion of the device which is made of an elongated strip of sheet metal, preferably tin. One end of the strip 10 is provided, in blank, with laterally extending wings 11 and 12 which are adapted to be folded along the dotted lines, as shown in Fig. 6, to provide a housing generally indicated by the numeral 13,

the top thereof being slightly inclined from its outer end. In the formation of the housing, the extensions 14 whichform locking tongues are first bent upon their folding lines so that when the housing is formed, said tongues will assume the parallel and then inwardly converging or inclined positions shown in Fig. 4 of the drawing. rlhe wing 11 isv then bent to form the side 15 of the housing 13 and thetop 16 thereof, which operation will bring the locking tongues 14 in the position previously described. The extremity ofthe wing 11 is then bent to form a U-shaped portion 17 which provides a longitudinal groove for the reception of the extremity 18 of the lateral wing 12 which is also bent to form an inverted U-shaped portion 19, as clearly shown in Fig. 1. The interlocking joint formed by the extremities of the two wings 11 and 12 provides the other longitudinal side of the housing. The wing 11 isprovided with an extension 20 opposite the locking tongue 14 thereof which is bent to form a closure for the rear end of the housing 13 after the other parts have been folded as just described.

The other end of the body portion 10 is reduced as indicated at 21 to provide an extension 22, the extremity of which is folded along the dotted lines shown in Fig. 6 to form the oppositely disposed locking lugs 23. In the formation of the lugs 23 the extremity 22 is first folded along the two innermost dotted lines on one side of the main body portion to form one ofthe locking lugs and then bent on the remaining lines to provide the locking lug on the opposite side of the body portion. Inwardly from the locking lugs 23 and adjacent to the inner end of the reduced extension 22, the metal is struck up to provide the inclined lug 24 which, when the seal is in locked position, forms a closure for the outer end of the housing 13.

In practice, when it is desired to seal a car, one end of the seal is passed through the usual staple on the door of the car and the end of the body portion provided with the locking lugs 23 is then inserted into the housing 13. Said lugs will engage the locking tongues 14 and spread the samev apart until the inner ends of the lugs have passed the inner ends of the locking tongues when the closure 2O will be engaged by the lugs and said tongues will, by reason of their resiliency, spring back into their normal poY sitions and engage the inner ends of said lugs whereby further longitudinal movement of the locked end of the strip relative to the locking end thereof will be prevented. When the tongues 14 assume their locking position, the lug 24 will be entirely within the outer end of the casing and the locking tongue adjacent to the inclined surface of said lug will engage the same and exert suflicient pressure thereon to cause the side opposite the inclined surface to engage the other locking Astrip lso that the parts will assume the position shown in F ig. 2 and the locking lug 24 form the closure for the outer end of the housing 13 and prevent any lateral movement of the locked end of the strip relat-ive to the locking end of the strip.

From the foregoing description taken in connection with the accompanying drawing, it will be apparent that the invention provides a seal of simple construction, thus re` dueing the cost of manufacture to a minimum, and one which is eflieient in carrying out the purpose for which it is designed.

I claim l. A seal comprising a single strip of sheet metal bent at one end to provide a housing, a closure for the inner end of said housing, locking tongues converging inwardly from the outer end of said housing, the other end of said strip being bent upon itself to provide locking lugs on each side thereof adapted to engage said closure and the inner ends of said locking tongues whereby f relative longitudinal movement between the ends of the strip is prevented, and a closure for the outer end of said housing formed in the strip adjacent said locking lugs and adapted to prevent relative lateral movement between the housing and the portion of the strip inclosed therein.

2. A seal comprising a single strip of sheet metal bent and folded at one'end to @opten of this patent may be obtained for ve cents each, by addressing the Commissioner ei' Entente,L

provide a rectangular housing, a closure for the inner end of said housing, locking tongues converging inwardly from the end of said housing, the other end of said strip being intimately folded and refolded together to form a substantially solid rectangular locking block for entering said housing, said locking block being of dimensions to snugly fill the space within the housing between the innerend closure thereof and the ends of said tongues and to fill said space laterally whereby relative movement between said housing and strip end will be prevented, the ends of said tongues engaging the outer end of said block at each sideof the strip whereby to prevent withdrawal of the strip end after insertion thereof into the housing.

3. A seal comprising a single strip of sheet metal bent and folded at one end to provide a rect-angular housing, a closure for the inner end of said'housing,` locking tongues converging inwardly from the end of said housing, the other end of said strip being intimately folded and refolded together to form a substantially solid rectangular looking block for entering said housing, said locking block beingof dimensions to snugly fill the space Ywithin the housingbetween the inner end closure thereof and the ends of said tongues and to fill said space laterally whereby relative movement between said housing and strip end'will be prevented, the ends of said tongues engaging the outer end of said block at each side of the strip whereby to prevent withdrawal of the strip end after insertion thereof into the housing, and a closure for the outer end of said housing formed in the strip adjacent said looking block, said closure completely closing the outer end of said housing.
