Show J Good Portable Lock. I A portable door and window lock f that can be carried in the pocket and applied anywhere without nails or screws has recently been invented by B. N. Wiekwire of Carbondnie. Pa. It consists of a wedge that is placed between the door and the doorjamb. 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 cttempts to open the door the movement wolges the lock into the jamb and the teeth grip so firmly ftmt the entire doVir frame must be torn away, the inventor declares, bef'tr-- the lock can be forced. |
