OTEY R. KIRKPATRICK, OF MINERAL WELLS, TEXAS, ASSIGNOR OF ONE-HALF TO
J. MACK SMITH, OF MINERAL WELLS, TEXAS.
PERMUTATION-LOCK.1,246,610.
Specification of Letters Patent.
Patented Nov. 13, 1917.
Application filed October 2, 1916. Serial No. 123,259.
To al 'whom it may concern:
Be it known that I, OTEY R. KIEKPATRICK,
a citizen of the United States, residing at
Mineral Wells, in the county of Palo Pinto
5 and State of Texas, have invented certain
new and useful Improvements in Permuta-
tion-Locks, of which the following is a
specification.
My invention relates to permutation locks
10 for milk bottles and other articles; and the
object is to provide boxes or receptacles
which will protect milk. bottles and other
articles against theft. It is well known that
milk is delivered in bottles by carriers who
15 deliver the bottles before daylight and that
the bottles of milk are often stolen. The
object of this invention is to provide a small
receptacle in which the bottles or other arti-
cles can be placed and securely locked.
20 Milk bottles are mentioned because they are
delivered in the dark and are stolen in the
dark of the night. It is apparent that the
improved locked boxes can be used for
various other purposes, as articles of mer-
25 chandise which are delivered when parties
are away from home. Another object is to
provide locking devices which can be oper-
ated by sound, that is, the locking devices
create sounds by which the operator can
30 lock and unlock the boxes in the dark.
Other objects and advantages will be fully
explained in the following description and
the invention will be more particularly
pointed out in the claim.
35 Reference is had to the accompanying
drawings which form a part of this appli-
cation.

several views.
The improved receptacle herein show u
may be constructed of sheet metal. The
box 1 may be of any suitable dimensions and 0
may be attached to the side of the house or
other place by screws 2 from the inside of
the box so that a person cannot unscrew the
screws and take away the box. The- box is
provided with a door 3 which may be suit- 65
ably hinged to the box. A locking bolt 4
is slidably mounted on the inside of the door
3 by means of brackets 5 attached to the
door. This bolt has a locking member or
lug 6 projecting inwardly to be engaged by 70
the rotatable locking disks 7 and 8, these
disks having recesses 9 and 10 respectively,
to be engaged by the locking lug 6. The
bolt 4 has also a lug or knob 11 projecting
outwardly through a slot 12 in the door 3 75
so that the bolt can be moved by the hand
when it is released for releasing the door 3
and also for locking the door. The bolt 4
may engage any suitable stop 13 which is
attached to the interior of the box. The 80
bolt 4 is held in the locked position by two
rotatable disks 7 and 8 which are provided
with recesses 9 and 10 to receive the locking
lug 6 and the box can be unlocked only
when the recesses 9 and 10 are brought in 85
alinement and in position to receive the lug
6 so that the bolt may be shifted to release
the stop 13. The inner disk 7 is rotated by
means of a shaft which has a square portion
14 which enters a square opening 15 in the 90
disk 7. The shaft is turned by means of a
knob 16 and the shaft has a cylindrical por-
tion 17 which is journaled in a sleeve 17.
The disk 8 is revolved or rotated by a sleeve
shaft which has a square portion 18 which 95
enters a square recess in the disk 8 and
which has a cylindrical portion 19 which is
journaled in the door 3. The sleeve 19 is
turned by a knob 20 which is rigid with the
part 19. The knob 20 is provided with a. 100
gaging lug 21 for locating the turns or
starting point of the knob. The knob 16
is also provided with a gaging lug 22 for
the same purpose.
The sounding devices include a spring 23 105
which is attached to the inside of the door
and has a central arm 24 which is perfo-
rated to receive the shaft 17. The spring 23
will thus be prevented from being shifted
out of place. Each disk 7 and 8 has a plu- 110
