This invention, relates, in general, to looks, and
haslparticular relation to an improved form of
panying drawing which illustrates the manner,
of constructing and using a lock embodyingthe
door lock of the type having a dead-bolt operated
by a key, combination, knob, or the like.
Inthe usual dead-bolt type of lock the bolt
must‘be actuated to retracted position, for ‘exam
ple, by a key, combination, knob, or the like, to
permit the door to be closed.‘ Then upon closing
the door the key, combination, knob, or the like
must be manipulated to move the bolt to ex

Another objectof the invention is to provide 45
a lock of the class described having various fea- ‘
turesof novelty and advantages, and which is
particularly characterized by its effectiveness
and security in use, its simplicity in construction,
its economy in manufacture, and its adaptability 50
for use with any lock in which the bolt is not
withdrawn, for example, by closing of the door.
Further objects and advantages of the inven
tion will‘appear from the following detailed de
scription, taken in‘ connection with ‘the accom 55
shown fragmentarilyat ll.

,
The dead-bolt I! on the door I0 is shown in
extended position. It is moved“ to extended and
retracted positions by mechanism under the con
trol, for example, of a key, combination, knob or
the like.
This latter mechanism per se forms no
part of the present invention, and therefore has
not been shown or described.

The lock of my present invention comprises an
angular bracket l5 attached‘to the door jamb II
and provided at the inner corner thereof with an
opening l6 which is adapted to receive the ‘ex
tended bolt 12 upon movement of the door'illl to
closed position. A locking plate 11 is pivoted‘ at
I8 to the inner side of one leg of the bracket l5.
An actuating member'l9‘is pivoted at 20‘ to‘the
inner side of the other leg of thelvracket I5." "I‘he
