GEORGE L. KITSON AND JOSEPH BENNOR, OF PHILADELPHIA, PA., ASSIGN- ORS TO THEMSELVES AND GEORGE IV. CARR, OE SAME PLACE.
IMPROVEMENTJN SEAL-LOCKS.
Specification forming part of Letters Patent No. 135,818, dated February ll, i573.
To all whom 'it may concern:
Be it'known that we, GEORGE L. KrrsoN and JOSEPH BENNOR, both of the city and county of Philadelphia, State of Pennsylvania, have invented an Improved Detective-Lock,ofwhich the following is a speeiiication:
The object of our invention is to prevent un authorized persons from tampering with or attempting to piek the locks of mail-bags, Sto., by enabling any such attempt to be detected with certainty by an after examination of the lock; and we accomplish this object by a rotary post, B, having an extension, A, armed with points y y, which, on the revolution of the post, (caused by a key-pickin g instrument, or otherwise,) mutilate a sheet of paper, X, which is confined between a hinged cap, D, and the back of the lock-case H, the mutilation of the paper indica-tin gto a certainty that thelock has been tampered with. An opening opposite the mutilator in the cap D may be covered with a sheet of glass, so as to permit the condition'of the paper to be ascertained without opening the case.,
Our invention may be applied to locks of various constructions, but is especially applicable to the spring-padlock illustrated in the perspective view, Fig. 2, and interior view, Fig. 3, of the accompanying drawing.
This loch is or' t-he most simple character, Y
and can be used for mail-bags,casl1boxes, and,
in fact, for any of the purposes to which padlock, one for the hasp and the other for the hinged cap, it' it be desired to complicate the parts in order to increa se the diiculty oi' piel@ ing the lock.
XVe claim as our invention- The post B, slotted to receive'a key which operates the tulnblers of the lock, provided with points, as set forth, and conned so as to have a rotary motion only, as specified.
In testimony whereof we have signed our names to this specification in the presence ot' two subscribing witnesses.
GEORGE L. KITSON. JOSEPH BENNOR.
