IMPROVEMENT IN SEAL-LOCKS.

Specification forming part of Letters Patent No. 147,219, dated February 3, 1574; application filed January 14, 1874.

To all whom yit 'may' concern Be it known that I, HERRNANN Ai-IREND, of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Seal-Locks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of referencemarked thereon, which forni a part of this specification.

The nature of my invention consists partieularly in the peculiar construction of the sealing or locking key, whereby the lock may be quickly and securely locked and sealed, so as to prevent it from being opened without detection.

In order to enable others skilled in the art to which my invention appert-aius to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure lis a side view of a seal-lock embodying my invention. Fig. 2 is a longitudinal section of the same. Fig. 3 is a section through the line Fig. 1. Fig. 4 is a section through the line y y, Fig. 1. Fig. 5 is a seetion through the line z z, Fig. 2, and Fig. 6 is an edge view of the key.

A represents the casin g of the lock, having the general form of a rectangle, and provided at its upper end with a horizontally-proiecting arm, B. C represents the hasp sliding within the case, and provided at its lower end with aiiange or shoulder, a, which meets a similar lian ge or shoulder, a', at the upper end of the case, to vprevent the withdrawl of the hasp. At a suitable point in the sides of the ease A are made slits b b, opposite each other, of suitable size to admit a key, D, which is made of a thin strip of sheet metal. Corresponding with the slits b in the lock-case is a recess, d, made in the hasp G, and the bottom of this recess is made convex, as shown in Figs. et and 5. The keyD passes through the slits b b, and through the recess d in the hasp, preventing the hasp from bein g moved and the lock opened. In order to prevent the key from being withA drawn by unauthorized persons, a shoulder, j', is formed upon each of its sides near the outer end, thereby preventing the key from being passed inward beyond a certain point; and to prevent its movement in the opposite direction, a tongue, h, is cut out of each side of the key, and said tongues ksprung in opposite di-4 rectionsthat is, one upward and the other downward. rIhese tongues form no impediment for the insertion of the key; but, as soon as the key is inserted as far as the shoulders ff, the tongues spring outward in opposite directions, forming a lock against the inside of the case above and below the key. This key cannot be removed without being broken, and hence not without detection, as, even it'vany instrument could possibly be inserted 011 one side of the key, it would only affect one ot the tongues, and the other would remain in place to hold it locked.

llo open the lock, the kcy must be broken ott at the shoulders ff, when itoan be pulled out from the other end.

The large end of the key I) may 'have a name, number, or any other desired mark stamped or otherwise affixed to it, as is usual in such locks.

I-Iaving thus fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

The key D, provided with the shoulders j' f and the tongues h h, bent or sprung in opposite direct-ions, in combination with the slits b in the lock-oase, and recess d in the hasp, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I aflix my signature in presence 'oi' two witnesses..
