CAR SEAL.

Application tiled December15, 1919. Serial No. 345,075.

To all whom t may concern.'

Be it lrnown that l, BRUCE BoRLAND,

citizen of the United States, residing at Chicago, .in theY county ofxCook and State of lllinois, haveI invented certain new anduse-` ful yImprovements in Cary Seals, of whichthe, following` is a` specication.

.This invention relates tok seals yof the character commonly known as car seals, on ac: count of their being used for sealing freight cars, but the. device isv also applicable for verA rious other uses.

rlhe objects Yof this invention are to pro` vide anew and improved. form of'sealadapt-L ed for sealing cars or` the like; toprovide av which maybe cheaply constructed; to`

provide a sealwhich may be readily applied and which can not be easily 4tampered with without such tampering becoming evident; and to provide a device having suchfurther advantages and novel features as willbel des scribed more fully hereinafter.

ln the accompanying drawings illustrating a preferred form of my invention z,

-Fignre l a perspective. view; i

Figure 2 is a vplan view of the main strip` or loop portieri ready for assembling;

Figure 3 is a detail ofv the locking end.

Cal); l

Figure Ll-is an enlarged longitudinal sectional view `of the locking portion; and

Figure 5 is a cross-.section taken on the line 5-5 of Fig. 4.

1t will be understood that these seals are ordinarily made of tin or light sheet meta-l and the device is shown in the drawings on an enlarged scale for convenience in illustration.

Although the device may in some instances be made of a single piece of metal, I prefer to make the same in two parts comprising a main strip 6 and a locking cap 7. The main strip 6 which forms the loop h-as a slightly enlarged head or portion 8 at one end, the sides being preferably notched or cut away as shown at 9 between the strip and head portion. This head is preferably corrugated or ridged in any suit-able manner as indicated at 10 which serves to stiften the same and prevent its being bent without injuring or destroying the seal. The edges of the head S are bent to form a flange 11 for engagement with the locking end T for holding lthe parts together. rlhe locking end or catch portion T comprises a plate 12 which fits closely within the flange 11 so that this. flange may be4 bent overA as shown in` Eigures. l, e ando to hold-the catchmember in position. Thiscatch portion has acentral'f longitudinal raised portion 1'3 forming an f innerrecessll, and also. hasianf integrally formed tongue-15 which-ispressed to formy Hanges 1.7' and having. a shoulderlg.v This tongue is,k bent linwardly 'into :the recesslt, as shown in Figures 4 andv 5, before 'thefpz'ir'ts` are assembled. :This tongue-oncatch .is

n somewhatresilient so `that .the endr will en-y f, a channel shaped catch '1d-having. `side?` i gage. with the latch or J'astening,portion-y ofthe strip,.,19.q This latch orfastening portion is preferab-lyA madefsomewhat nar;` Y

rower than the mainportion of the strip so that. shoulders 20 will 'bev formed adjacent tothe end.v The lfatchl9cis. pressed into a, channel shape withv side flangesQ-l and hasA a shoulder 22, this portion of the deviceV c on forming closely to the catch.. 16- andadapted to,k fitk over the same asf. shownin VFigures 4l'` and 5. The latch portion 19; hasja locking projection 23 which ,is preferably punchedv up from'the body of thecmetaland also preferably providedt. with a .plurality off similar projections 221 whichare'; adapted for purposes which will presently be explained.

The strip or. band G` is 4also provided with" a hol el 2 5, adjacent tothe latch end, the inetah arouniil 4the hole being corrugated, ias shown;

at 26. .This hole serves for the., purpose of Stringingr they seals and forthe furthen purpose. of Ipreventingy tampering therewith. lt' it is attempted to cut or break the seal adjacent to the shoulders 20 and insert `the loose end into the recess 14, it would be necessary to out off th'estrip beyond the hole so that the tampering would be plainly apparent.

When the parts have been formed in the manner described and assembled as shown in the drawings', the seal will be locked when the latch portion 19 is inserted in the recess' or aperture 111, at which time the channel shaped catch 16 will nest in the similarly formed channell shaped latch 19, and the en d of the catch will engage with the projection 23 to lock the parts together. lt will be noted that comparatively small space or clearance needs be left between the shoulder 9.2 o-f the latch and the shouder 18 of the locking tongue in order to insure the engagement of the locking parts so `that thereI will be little or no play between the locking parts after the catch has engaged with the locking projection. The projections m serve to preventl the. unlocking of the device by inserting a'strip between thelatch and catch portions, as such strip would strike the projections before it could be inserted a sutlicient distance ytorais'e the end of the The flanges on the different, 'parts not only serve to stiften the same but also further serve to prevent the tampering tongue 15.

with the device. Y

From this description it will be seen that I provide an exceedingly simple car seal which may be readily constructed and which will be ecient in use, but it will be noted that changes may be made in the details of material having a longitudinal pocket at'one end thereof, with an inwardly projecting tongue, and having a latch portion at the opposite end thereof which isnarrovver than the strip and is provided with side flanges and has a shoulder at its inner` end which is adapted to be inserted in said pocket and having a projection orengagementwith thetongue. t

2. A car seal comprising a metallic strip having a longitudinally arranged pocket or recess at one end, with an inwardly project@ ing flanged catch, andhaving a flanged latch at the opposite end adapted to tit over said catchvand having a projection which engages with the catch when the latch is inserted in the pocket.

8. In a car seal, the combination out a me! tallic strip having acorrugated head at one end, a locking cap secured to said head and having a longitudinal opening therein, a resilient flanged tongue projecting inwardly from the open end of the cap, a flanged locking portion at the'opposite end'of the strip adapted to fit over said flanged tongue, and having a projection for engagement with the end of the tongue when said lock- `ing end has been vinserted in said recess.

Il. In a seal, the combination rof a metallic band, having a locking cap at one end with a recess therein, and having a resilientflanged tongue projecting into said recess, said tongue having'a shoulder at its outer end, and a anged and shouldered engaging portion at. the opposite end of the band adapted to tit closely over said'tongue, sol `that the tongue will be nested therein, said engaging .portion having a projection V,for

engagement with the end of the tongue when the engaging portion is inserted in the locking-cap. i

5. In vav seal of thev character described,

the'combination 'of a metallic striphavinga corrugated head atone endthereot, alock-v ing cap having kany outwardly `projecting flange securedto the head by havingthe edges of the head bent over said ange, said cap having a longitudinal recess, and'being closed at its outer end, said capalso having an integrally formed resilient tongue projecting into said recess, said tongue having flanges at the sides thereot'and having a shoulder adjacent to its Xed end, the opposite end of the strip having a flanged and shouldered engaging portion adapted to fit over said tongue and having aprojection for engagement with the end of the tongue when the engaging portion has been fully inserted in the cap, said engaging portion also having one or more projections in advance of the locking projection, the arrangement being such that when the engaging portion is inserted in the cap, it will tit over the flanged tongue and be securely held rbetween the tongue and head, substantially as described.
