OTTO EDLER, OF HANOVER, GERIVIANY.
SEAL-LOCK.
T 0 all whom it may concern:
Be it known that I, O'r'ro EDLER, a citizen of Germany, residing at Hanover, Germany, have invented new and useful Improvements in Seal-Locks, of which the following is a specification.
This invention relates to the seal locks of books, more particularly loose-leaf ledgers or the like and has for its object to provide a device which will prevent unauthorized use of the key whereby the book is opened or pages removed.
According to this invention a fiat box is disposed above the keyhole and provided with slots on its upper and under surfaces, the lower slot being adapted to receive the keyhole rim, while the upper slot is of such shape that two paper or similar strips can be introduced through it into the two lateral portions of the box. These two paper strips which cover the keyhole, are then connected together by means of a seal or the like, so that it is impossible to get to the keyhole without destroying the seal.
One construction according to this invention is illustrated by way of example in the accompanying drawings, in which Figure l is a perspective view of a looseleaf book, provided with my improved seal lock, Fig. 2 is a plan of the box, and Fig. 3 is a central cross section of Fig. 2.
In the construction shown the keyhole a of the loose-leaf book 6 (Fig. 1) is adapted to have a box 6 shown in Figs. 2 and 8, used in connection with it as a sealing device. The box 0 is provided on its under Specification of Letters Patent.

Serial No. 487,519.
surface with a circular slot cl adapted to surround the keyhole rim 0, and on its upper surface has an opening f which enables two paper strips 9, 72, to be introduced into the box, the superimposed edges of which are then connected by a seal 2'. This seal is so positioned that it extends over the overlapping edge of strips 9, h, and is pasted on one side of said edge to strip 9, and 011 the other side to strip h. Without destroying the seal, it is then impossible to get to the keyhole a.
Although particularly intended for use in connection with loose-leaf ledgers and the like the device may also be used on the locks employed to retain such books or ordinary volumes closed.
What I claim is:
1. A. seal lock for loose-leaf or other books comprising two strips of paper or the like inserted between the keyhole and projections above the latter and having their superimposed edges connected by a seal as set forth.
2. A device of the character described, comprising a box having a lower slot adapted to receive a key hole rim, an upper opening, a pair of overlapping paper strips interposed between said slot and opening, and a seal projecting over the overlapping edges of said strips.
Signed by me at Hanover, Germany, this eighteenth day of March 1909.
