Show Good Portable Lock. A portable door and window lock that can be carried la the pocket and applied anywhere without nails or screws has recently been invented by B. N. Wlckwlre of Carbondnie, Pa. It consists of a wedge that Is placed between the door and the doorjnmb. The wedge carries a series of fine teeth that are brought lightly Into contact con-tact with the wood by pressure upon a lever. If anyone attempts to open the door the movement wedges the lock Into the Jamb and the teeth grip so firmly that the entire door frame must be torn away, the Inventor declares, before the lock can be forced. |
