LOCK.
JPEQlFICATION forming part of Letters Patent No. 729,098, dated May 26, 1903. Application 1116a August so, 1902. ri 121,625- N m l- To all whom, it may concern.-
Be it known that I, BATTESE REVOIR, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Locks, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
My invention relates to improvements in locks, and refers more particularly to means actuated by the locking-bolt for retaining the key in position in the locks and for partially closing the keyhole to prevent the removal of the key or malicious tampering with the lock.
Referring to the drawings, Figures 1 and 2 are face views of portions of the inner mechanism of an ordinary lock, showing the application of my invention thereto, the lock and bolt being shown as withdrawn or unlocked in Fig. l and in its unlocking position in Fig. 2. Fig. 3 is a sectional view, taken on line 3 3, Fig. '2, showing the key in operating position. Fig. 4 is a perspective view otthe detached locking-bolt, showing the key-locking member thereon. Fig. 5 is a view similar to Fig. 1, showing the locking-bolt as provided with a key-locking member for locking the key when the bolt is withdrawn or unlocked; Fig. 6 is a sectional view taken on line 6 6, Fig. 5.
. Similar reference characters indicate corresponding parts in all the views.
Myinvention is designed to prevent the removal of the key from the keyhole either for the purpose of maliciously unlocking a door or other device provided with a locking-bolt controlled by a key, as shown in Figs. 1, 2, 3, and 4, and also preventing the accidental displacement of the key when the door is unlocked, as seen in Figs. 5 and 6.
It is well known that when a door or other closure is locked by a key and a burglar or intruder desires to enter the building through said door the key is usually pushed inwardly through the keyhole, and a skeleton key or other device in the hands of a skilled person can then be inserted into the keyhole and the bolt withdrawn to unlock the door. In order to prevent this, I provide the bolt with a suitable member which interlocks with the bit of the key when the bolt is locked and not only prevents the removal of the key, but also practically closes the keyhole against the insertion of any tool which might be used to withdraw the bolt.
In Figs. 1 to 4, inclusive, I have shown the lock provided with a locking-bolt 1, a tumbler 2,and a key-locking member 3, movable across an ordinary keyhole 4. The bolt 1 and tumbler 2 maybe of any desired construction adapted to be operated by a key, as 5, Fig. 3. These parts being well understood, it is thought to be unnecessary to enter into further description of the same.
The key-locking member 3 forms the essential feature of my invention and consists of a hook-shaped arm secured to and preferably forming a part of the inner end of the locking-bolt 1, said arm being so arranged that when the bolt is withdrawn, as seen in Fig. 1, the arm 3 is normally out of the path of the keyway 4, and when the bolt is moved to its locking position, as seen in Fig. 2, the arm 3 is moved across the opening 4, between the bit, as 6, of the key and the wall of the lockcase, as 7, adjacent to the collar, as 8, of the key. It is therefore evident that when the arm 3 is in the position seen in Fig. 2, across the key-opening and between the bit 6 and wall 7, the key5 may be freely rotated in the key-opening, but cannot be withdrawn through the keyhole 4. In'like manner when it is desired to hold the key from accidental displacement when the bolt is withdrawn, as seen in Fig. 5, I provide the locking-bolt 1 with a key-locking member 3, similar to the arm 3, but secured to the locking-bolt at the opposite side of the keyhole, so that when said bolt is withdrawn the arm 3 extends across the opening 4 between the bit of the key and the wall of the lock-case adjacent to the collar of the key.
The construction and operation of my invention being extremely simple the merits are believed to be apparent without further description.
Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-
1. The combination with a key-operated locking-bolt, actuated in both directions by the turning of the key, of a key-locking member on the bolt interlocking with the bit of inner end extended downwardly and laterally the key when the bolt is moved in one direotoward the outer end of the bolt and movable tion for preventing removal of the said key. across the opening between the bit of the key 15 2.
