Patented Apr. 25, 1933 UNITED STATES BRUCE BORLAND, or lomcaeo, ILLINoIs Application led November 3th),V ,179,253.1r Serial No.- 410,78`1. i teyenath button. Thetop 12 of the button This invention relates to car seals or the like and is particularly directed to seals of this character which are self-locking as distinguished from those requiring a seal press for fastening the same.

The objects of this invention are to pro- Vide an improved self-locking seal which may be cheaply manufactured and which will be effective in use; to provide a seal having a cap or coacting member having means for engaging with said catches to hold the parts in locked position; to provide a seal having locking members which are covered or pered with or unfastened without being broken and to provide such other novel features and improvements in construction as will appear from the following description.

In the accompanying drawing illustrating this invention:

Figure 1 is a side view of a complete seal shown in locked position;

Figure 2 is an enlarged sectional view of the locking or fastening members shown 1n partially engaged position;

Figure 3 is a sectional view simllar to Flgure 2 but showing the parts in engaged or fastened position;

Figure 4 is a plan view of a portion of the seal and button;

Figure 5 is a plan view of the cap or coacting engaging end;

Figure 6 is a sectional view showing a slightly modified form of constructlon; and

Figure 7 shows a further modified form of construction.

My improved seal as shown 1n the drawing, comprises a strip 8 which 1s preferably formed of metal and which has sealing or fastening members to form a closed loop. In the commercial forms for car seals these strips are formed of tin about 1/8 of an inch wide. A button or projection 9 is provided adjacent to one end of the strip and is preferably formed integrally therewith. In the forming of this button the edges of the strip are drawn in making recesses 10 which project in approximate] to the base of the button and a short ta 11 is left projecting locking button provided with catches, and a` pro tected so that the seal cannot be easily tam isY preferably flattened so that the button ywill project outwardly as short a distancey as possible.A This hollow projection orf-button has one or more tonguesor catches 13 in the sides thereof,` ,these tongues beingformed' by cuti ting orslitting the 4sides of the button from the toptofthebottom and punching or cutf ist ting ontsections'to form holes 14atthe lower .i

lends of the tongues. The lower ends of the tongues are bent outwardly beyond theadjaf cent surface o f thel button.. and will :have a certainz amount of resiliency.` l

The strip 8 is provided With a hollowcap or' coacting. fastening member for Yengagement with the button 9. In the particular arrangement shown this capl is formed-"ad-v jacent to4 the end 16 of the strip. This p0rtionof the stripV is then folded closely upon itself to provide a cover or top 17 forthejopen cap' orV projection 15. Thiscover portion has an inwardly projecting annular flange orbead ISMitting tightly in theadjacent end of the cap l5 `as. Vclearly shown in Figure 2; The stripV 8 is again folded so that the cap or pro-l jection 15 will pass through a hole 19 inthe strip and extend outfonv the opposite side in positionlfor engagementwith the'button 9.

p The cap or Afastening member 15 .is turned inwardly at its loweredge to provideflocking or fastening means for, engagement with the lower ends of the tongues or catches 18. V' `This inwardly "turnedflangejor edge 20 preferably extends around the inner circumference o f the `cap and "fits closely against the base or largest diameter of the button"V V `IVhen theseal is to be fastened or locked,` the vc-"apl isvbrought'into engagement with the button preferably' as shown Vin Figure' 2,' one side of the cap'being placed over thev but` ton until the edge or flange 20 engages with the lowerendof the outer tongue 13, and then the button Vis rocked,` or svtfungI downwardly until the opposite portion of the flange engages with thetongue orcatch 13 on the op-l posite sideof the button.: VVhenvv the parts are thus brought into fastening or locking rela# tionas shown Vin Figure Sit will be practical= ly impossible to disengage such fastening members without breaking the seal. f It will.

yof the button.

Ybroken off as it'onlyhas short connecting portions uniting it with the button. The cover 17 fully protects the upper portion of the button so that it release the tongues from engaging position. Furthermore after the iiange or rim fastening position the lower ends of the tongues will extend over thev same' so that it will be diilicult to disengage the tongues byrreaching through the open bottom or end However, the ends ther protected in the device shown inFigure 6 by merely making slits to sever the lower ends and leaving oppositely disposed sections 21 of the lsides of the this figure. These sections will further prevent the possibility of tampering with the tongues by means of any tool inserted vin the button. e

In the device shown in Figure 7 this yoint is further protected vso that there cou d be no ossibility of tampering in this manner. In t is arrangement the button 23 is formed adjacent'to one end of the strip 24 and a fold made to provide a for the button. This cover portion has an inwardly projecting annular .flange 26 similar to the iange 18 shown in Figure 2. Another fold is made in the strip and the button is passed through a hold 27 in the strip 24: thereby making three layers of the strip adjacent to the button. When a locking cap suchas the cap 15 is broughtinto engagement with this type of button, the ends of the tongues 28 will be fully protected both from the lower or underside and the top or cap side and the fastening or engaging portions lock the several plies or layers at the respective ends of the strip so that the fastener cannot be disengaged without injuring the strip. While I have described my seal in connection with those of the car seal type, it will be apparent that various forms may be made for dierent purposes and therefore I do not lwish to be limited to the particular arrangement or construction shown and described except as set forth inthe following claim in which I claim: 4
