SEAL-LOCK.

ed to be secured against tampering, by a seal which must be broken before the unlocking can be efiected.

It consists in the elements and features of construction shown and described as indicated in the claims.

In the drawings :Figure 1 isa vertical transverse section of a box having its lid secured by a lock embodying this invention, the lock being shown in side elevation with the parts, including the seal, at locked position but not sealed. Fig. 2 is a front elevation of a box secured by a hasp and staple, and having a lock embodying this invention applied for securing the hasp, the lock with its bolt and sealing device being shown at locking position, but not sealed. Fig. 3 is*a section at the line 38 on Fig. 2. Fig. 4 is a plan view of the combined bolt and seal.

The lock shown in the drawings comprises a bolt housing, 1, and a flat metal bolt and seal, 2, operating in a slide-way or slide path, 3, in the housing, and having one end adapted to serve as the locking bolt when the said combined seal and bolt is thrust longitudinally in the slide-way to the locking position. In the form illustrated in Fig. 1, which shows the lock applied to a box, A, having a hinged lid, B, provided with a lip or flange, C, which shuts down outside of the vertical wall of the box, the bolt end of the combined bolt and seal is shown less than the, full width of said bolt and seal, which isimade of comparatively fiat metal plate or comparatively thick sheet, and positioned so as to stand edgewise to the pull which might be exerted upon it in attempting to open the box while locked. In the form shown in Fig. 2, in which the device is adapted to a hasp and staple construction, the seal housing has the function of the staple, and the seal bolt protruding at both ends stops the hasp. The essential feature characterizing the device is the provision for scaling, in which the seal is made to serve also as the bolt, the lock being without any bolt other than that furnished by the sealing member. The housing has an aperture, 4, which extends transversely of the slide path of the bolt and seal, so that the latter is exposed through said aperture of the housing I at locked position; and the said bolt and seal has an aperture, 5, which approximately registers with said aperture, 4, of the housing at said locking position, and hasprojecting from one end of said aperture, 5, a

tongue, 6, which at the locking position of the seal bolt stands exposed in said aperture,

4, of the housing and adjacent to the edge thereof, past which it is thrust in inserting, and may be engaged by the finger inserted ""in' the notch, 4 at the lower edge ofsaid aperture, 4, to bend the tongue into a position transverse to the plane of the seal bolt so that said tongue extends across said adjacent edge of the aperture, 4, and prevents the withdrawal of the seal bolt. The side of the aperture adjacent to whose edge the tongue is thus positioned for bending, and across which it is bent for securing, may be regarded as a guard without regard to the fact that it is a part of the continuous boundary of the aperture, 4.

The metal of which the seal-bolt is formed and the length of the line across the tongue at which the bend occurs when it is thus bent to scaling position, are such that if the tongue is bent back to this original position in the plane of the seal, it will break at this line. Whether the breaking occurs or not, the seal bolt can be withdrawn upon the tongue being bent back to its normal position; but the provision for causing the tongue to break off when thus restored to position is necessary in order that any unauthorized tampering with the device for unlocking may be disclosed by the fact that the seal tongue will be thus broken ofi. The aperture, 4, of the housing is of such dimensions that the tongue, 6, exposed therein may be large enough to bear an easily recognizable identifying mark, which serves as a protection against the substitution of an other seal bolt when the original seal bolt has been removed by an unauthorized person breaking the seal tongue.

I claim 1. A seal lock comprising a housing, and a flat metal seal bolt mounted for sliding in the housing; the housing having a slide path for the bolt and a guard past which the adapted to be bent out of the plane of sliding into a plane extending transversely of the slide pat-h and across the edge of the guard, and to break at the line of bending upon being straightened back into its original position.

2. A seal lock comprising a housing and a flat metal seal bolt mounted for sliding in the housing, adapted to protrude therefrom for locking the housing, having a slide path for said seal bolt and a guard past which said slide path extends,the seal bolt having a tongue which extends normally in the plane of sliding and which at locking position of the seal bolt is exposed and accessible adjacent to the guard, and beyond the same in the direction of insertion, said tongue being adapted to be bent transversely to its normal plane so as to extend across the edge of the guard, and to break at the line of bending upon being straightened back into its normal plane.

3. A seal lock comprising a housing and a fiat metal seal bolt mounted for sliding in the housing, and adapted to protrude therefrom for locking the housing, having a slide path for the seal bolt and an aperture which penetrates that path, the seal bolt having a tongue Which stands normally in the plane of sliding and Which at the locking position of the bolt is exposed and accessible at said aperture of the housing and which is adapted to be bent in said housing aperture so as to extend transversely of its slide path and across the edge of the aperture, and to break at the line of bending upon being straightened back into its original position.

In testimony whereof, I have hereunto set my hand at Chicago, Illinois, this 24th day of February, 1913.
