Abstract
19,618. Royston, E. R., [Krohn, E. H. F.]. Sept. 8. Locks, key; latches.- The latch bolt d for a door &c. is pivoted to a bar divided into two parts c, f, the part c being operated by the follower of a handle. The part f is pressed downwards, by a spring e, into contact with the end of a spring - guided bolt g. The key for operating the locking-bolt h is provided with projections b for moving the bolt g, in addition to the bit a for moving the bolt h. In locking the door, the bolt g is moved downwards, and the spring e presses the part f out of engagement with the part c so that the latch bolt cannot be withdrawn by turning the handle. Should the bolt h be withdrawn, without the bolt g being moved upwards, then the door cannot be opened as the bolt d cannot be moved. When the bolt g is moved upwards, the part f is forced into engagement with the part c, and the bolt d can be withdrawn. The bitts for operating the bolt g may be formed on a separate key. The plate carrying the bolt g is cut away instead of being provided with a keyhole.
