THOMAS E. MURRAY, OF NEW YORK, Y.

SEAL-FASTENING.

Specification of Letters Patent.

Patented April 14, 1908.

Application flled October 8, 1907. Serial No. 396,464.

To all whom it may concern:

Be it known that I, THoMAs E. MURRAY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Im rovementin Seal-Fastenings,

. of which the to lowing .is a specification.

The invention is a seal fastening whereby two loops or eyes may be secured together by means of a-wire and holding block or seal body in such a way as that the ends of the said wire cannot be withdrawn from the holding block after insertion therein.

The object of the invention is to prevent the opening of doors, lids, covers, and the like, and generally the separation of objects whichit may be desirable to retain connected.

The invention consists in the construction of the wire fastening loop having its end portions turned backward to form portions of substantially V shape, a recess having two contracted entrances respectively receiving said V shaped portions and an enlarged inner cavity wherein said V shaped portions are free to expand and become locked by abutment of their extremities u on the inner surface of said recess: and w iereby the wire is permanently retained in the block, so that said block cannot be used a second time: also in the combinations more particularly set forth in the claims.

I In the accompanying drawings-Figure 1 is a vertical section on the line aca: of Fig. 3.-

Fig. 2 is a transverse section on the line yy of Fig.3, and Fig. 3 is a top view of my improved seal block. Fig.4 is a modified form also in section on line :c-a: of Fig. 3.

Similar numbers of reference indicate like arts.

The holding block or seal body 1 may be made of orcelain or other fictile material and of cyhndrical shape. It has an internal recess or cavity 2 with two contracted en- Opposite the solid partition betweensaid entrances, said recess is pro vided with an inward projection 5. The sides 6, 7, of the recess are inclined toward .the projection 5 and between said sides and the sides of the projection are formed curved seats 8, while between'said sides and the entrances are formed shoulders 9.

The fastening wire 10 is in loo form and has its end portions turned bacliwardly in substantially V shape. In each standing part of the wire and located between. its loop and the extremities of the turned back portions are crimps 11. In the form shown in Fig. 1, the end portions are turned backward and inward in V sha e and the crnnps 1] are bent inwardly. In t is form shown in Fig. 4,

the end ortions are turned backward and outward in V shape and the crimps are bent outwardly. In Fig. 1, 12 and 13 represent the eyes which are to be retained together by means of the device.

In operation, the turned back portions are presse' closely against the standing parts of the loop and inserted through the entrances 3, 4, until the a exes of the Vs are seated in the seats 8. Tie extremities of the VS on entering the recess spring away from. the standing arts of the wire. shown in ig.- 1, they both come opposite the In the form inner curved surface of the solid material of shaped portions. In both cases the orimps.

11 are received and fit in the entrances 3, 4. It is impossible to withdraw the wire from the holding block because in the form shown in Fig. 1 the extremities of the V shaped portions get an abutment on the solid material of the block between the entrances, while in Fig: 4 equally they get an abutment on the shoulders 9. Nor can each part of the wire be withdrawn separately from the block in case the loop wire is cut. possible to replace the fastening to re-use the seal block. I
