1 Claim.
This invention has reference to a handle and
lock construction and assembly for closures and
more particularly for automobile doors.
More particularly the invention has reference
5 to a combination or permutation lock, and an
object of the invention is to provide a lock of
this character characterized by simplicity of con
struction and assembly; and which will be found
e?icient and practical for use on automobile doors.
Further objects of the invention are to provide
a lock of this character for automobile doors
which will dispense with the need of carrying a
key for the door lock, and which can be worked
from a simple combination easily carried in mind
15 and to that end will enable an operation of the
look under conditions precluding the ef?cient
lighting as is necessary in the case of those locks
of a permutation construction and which include
a dial for use in setting or releasing the lock.
Further in accordance with the present inven
tion a permutation lock of the character men
tioned is provided whereby the combination can
be Worked without relying on “sound” for deter
mining whether or not the combination is being
25 properly worked and which will therefore render
it most dif?cult, if not practically impossible of
being picked.
The invention together with its objects and
advantages will be best understood from a study

Referring to the drawings it will be seen that
the lock and handle of the present invention are
illustrated as applied to an automobile door a 10
portion of which is shown in the drawings and
indicated generally by the reference numeral ID.
The door i0 is of conventional construction and
is equipped with a locking bolt II housed within
a suitable casing mounted in one side of the
‘frame of the door and operated directly from an
inside handle I3 through the medium of a con
ventional lever I4 mounted on the squared por
tion of a shaft I5 to rotate with the shaft. Han
dle I3 as clearly shown in Figures 2 and 3 is
suitably secured to one end of the squared por
tion of the shaft 55 so that by properly manipu
lating the handle I3 motion is transmitted
through the member I4 to the bolt I I for project
ing or retracting the bolt. In this connection it
will be noted that at the inside thereof the door
I0 is provided with a conventional escutchecn
plate I6.
In accordance with the present invention there
is provided for the door IB an outside handle H 30
which is suitably connected as at it with one
end of a squared shaft I9 arranged substantially
in alinement with the shaft I5 and provided at
its inner end with a cylindrical socket 223 form
ing a bearing for the cylindrical end I52) of shaft
I 5. For the outside of the door there is pro
vided a suitable escutcheon plate 2!.
Further in accordance with the present inven
tion there is provided on the squared portion of
the shaft I5 a disk 22 having a squared opening
23 for receiving said squared portion of the shaft
I5 and also provided with a notch 24 in which is
pivoted as at 25 one end of a dog 25.
The opposite end of the dog 26 is adapted to
engage the periphery of a disk 21 provided with
a squared opening 28 receiving the shaft I9. The
disk 21 is also provided on its peripheral edge
with a flattened portion through which opens a
notch 29 which when the disk 21 is in a prede
termined position receives the free end of‘ the
dog 26 as shown in Figure 3 so that rotative
movement of the shaft I9 will be transmitted to
the shaft I5 for retracting the bolt II in a man
ner thought to be apparent.
Further the lock includes a pair of tumbler
2,1 17,420
disks 3!! and 3! respectively. The disks 3!! and
3! are provided at their centers with circular
openings 32 and 33 respectively which receive the
cylindrical portion I50 of shaft I5 so as to permit
rotation of the shaft I5 relative to the disks 3!!
and 3! under certain conditions.
Each disk 33 and 3! is provided with a circu
lar series of openings 34 and 35 respectively there
being preferably twelve openings in each disk
10 corresponding somewhat to the twelve numerals
on a clock dial although it will be understood
that a greater or lesser number of such open
ings may be resorted to if desired.
For use with the disk 3!! there are provided
ment of the handle I'! will be transmitted to
the several disks in predetermined sequence until
all of the disks have been moved into a prede
termined position alining the notches in the disks
and thereby permitting a movement of the dog
26 from the position shown in Figure 2 to the
position shown in Figure 3 whereby to place the
handle I'! in driving engagement with the shaft
I5, so to speak, so that a further turning of the
handle I‘! will result in a manipulation of the 10
bolt II for retracting the latter.
The manner in which the tumbler disks are
successively positioned for alining the notches
thereof with one another and with the notch 29
in the disk 21, and the notch 4‘! in the disk 4!] 15
is analogous to the manner in which tumbler
There is also provided a cam disk 40 which disks in any permutation locks are so properly
like the tumbler disk is provided with a centrally positioned and consequently a detailed descrip
located circular opening 4! for receiving the por- . tion of' this particular operation is deemed to be
unnecessary. However inactual practice it has
tion I5c of shaft I5; said disk being also pro
vided with a circular series of openings 42, the been found that by equipping each of the disks
openings 42 being one less in number than the 3!! and 3! with a series of twelve holes apiece
a combination may be formed whereby, in keep

Each disk 3!] and 3! is provided at a predeter
mined point with a notch 45 and 46 respectively through which the handle I‘! must be moved in
while the disk 40 is provided at a predetermined working the combination can be readily kept in
point with a substantially V-shaped notch 41 one mind and in addition thereto, one knowing the

The disks 38, 3! and 40 are arranged on the the handle I'! is in each required predetermined 30
position. In this way one having knowledge of
part I5c of the shaft as clearly shown in Fig
ures 2 and 3 and arranged in alternation on said the combination may readily operate the lock

are spacer washers 49, the washers and disks time the combination can be worked without the
operator being required to listen for any “click” 35

between will serve to prevent too free rotation of as is now generally required with permutation

there are provided pins 38 and 39.
the disks, and also to prevent premature trans
mission of movement from one disk to the other
when the lock is being operated.
Projecting from one face of the disk 2'! is
a properly positioned pin 49a for cooperation with
a pin 38 on a disk 3! for a purpose, and in a
manner hereinafter made manifest.
Depending from the underside of the dog 26
a lug 26a which engages in the notches 45,
45 and 4‘! of the disks 3!}, 3! and 4!! when said
notches are alined as shown in Figure 3 and at
which time the free end of the dog 26 is engaged
in the notch 29 of the disk 2‘! so that upon a
turning of the handle I‘! movement of the han
dle will be transmitted to the shaft I5 and from
the shaft I5 through the member I4 to the bolt
II for retracting the latter. In this connection
it will be understood that when the dog is in the
55 position shown in Figure 2 and the notches of
the several disks are out of alinement handle I‘!
may be freely turned in either direction without
effecting a movement of the bolt II. Thus un
der such circumstances and with the door of the
60 automobile closed unauthorized entry into the
automobile will be effectively precluded.
As is thought to ‘be apparent the holes in the
disks, and the arrangement of the pins in the
holes will permit a varying of the combination
from time to time if desired.
The operation, utility and advantages of the
invention will be apparent from the following:
It might be ?rst stated and is thought apparent,
that with the pins for each disk arranged in
70 the selected openings in the disks a predeter
mined manipulation of the handle I'!, ?rst turn
ing the same in one direction, and then in a re
verse direction for a certain fraction of a rev
olution, and then for a greater or smaller frac
75 tion of a revolution as the case may be, move
The above may be best understood from the
Thus with the pins 36, 31; 38, 39, and 43, 44 40
arranged in the relative ‘position shown the op
erator, to retract the bolt I I will manipulate the
handle I‘! in the following manner; the han
dle or knob I‘! is ?rst rotated in a clockwise di
rection until it assumes a position corresponding 45
to, for example, the numeral I! on the face of
a clock dial. This will result in positioning the
disk 40 so that its notch 4‘! is substantially in
alinement with the notch 24 in the disk 22. Next
the knob I‘! is rotated in an anti-clockwise di 50
rection to a position corresponding substantially
to the position of the numeral 8 on the face of
a clock dial.
This will result in a movement of
the disk 30 to a position alining its notch 45 with
the aforementioned notch 48 of disk 40.
Next 55
the operator rotates the knob I‘! in a clockwise
direction and the handle or knob I‘! is in a po
sition corresponding to the position of the nu
meral Son the face of a clock dial. This will
result in the alining of the notch 46 in the disk 60
3! with the aforementioned alined notches 4'!
and 45. The knob I‘! is then turned to the left
and as the knob is turned in this direction notch
29‘ in the disk 2‘! which turns with the knob
moves into alinement with the now alined 65
notches 48, 45 and 46. This permits the free end
of the dog 26 to drop into the notch 29 with the
lug 26a of the dog dropping into the alined
notches 48. 45 and 46, the position of the parts
being such as shown in Figure 3. With the 70
parts in this position it will be apparent that ro
tation of the knob I‘! in the proper direction will
result in a retraction of the bolt I I permitting the
door to be opened.
With the parts in the position shown in Fig
ure 3, when it is desired to secure the door In in
closed position against unauthorized opening the
dog 26 is raised out of the notch 29 in a manner
and through the instrumentality hereinafter de
scribed in detail. With the dog 26 in this raised
position knob I’! by gravity will rotate to the po
sition shown in Figure 2 thus moving the notch
29 of the disk to an out of the way position so
that the free end of the dog 26 will then rest on
10 the peripheral edge of the disk 21 in a manner
to hold the lug 26a thereof raised out of engage
ment with the notches 45, 46 and 41 of the disks
30, 3| and 40 as will be clear from a study of
Figure 2.
For this raising the dog 26 there is provided
a push button 50 mounted to slide in a cylinder
or casing 5| mounted in the door structure and
secured in position as at 52 at the inner side of
the door. Pin and groove means 53, 54 serve to
20 retain the knob 50 against rotative movement
and the knob 50 is normally urged to an up
wardly projected position through the medium
of a spring 55.
The knob 50 has a reduced
shank that projects through the bottom of the
25 cylinder or casing 5| and at its lower end there is
secured to the shank of the knob an angularly
disposed arm 55 in the path of which is arranged
the pin 44 of the disk 40 as shown in Figure 4.
Thus with the parts in position as shown in
30 Figures 3 and 4 the dog 26 is raised out of en
gagement with the notch 29 of disk 21 by press
ing downwardly on the button 50. Downward
movement of the button against the action of the
spring 55 will cause the arm 55 to engage the pin
44 thus rotating the disk 40 in a counterclock
wise direction. As disk 40 rotates in this direc
tion the cam edge 48 thereof will engage the
lower edge of the lug 50 with the result that dog
26 will be caused to swing vertically upwardly
40 from the position shown in Figure 3 to the posi
tion shown in Figure 2 and subsequently engage
the peripheral edge of the disk 21 whereby said
dog will be retained in the position shown in Fig
ure 2 until the knob I1 is again manipulated in a
manner hereinbefore described in detail for plac
ing the handle or knob H in driving engagement
with the shaft l5.
It is obvious that with the dog 26 in the raised
position shown in Figure 2 a haphazard manipu
lation of the handle I’! will be ineffective for re
tracting the bolt ll. Thus under such condi
tions, and with door. It closed it will be prac
tically impossible for an unauthorized person to
gain entrance to the automobile.
While I have described the lock as being par
ticularly adapted for‘use on automobile doors it
will be understood that the same may be applied
to doors of other structures or to any other suit
able type of closure.
Having thus described the invention, what is
claimed as new is:
In a lock of the character described, a pair of
alined shafts, said shafts being normally rotat
able independently of one another, and permu 20
tation means interposed between said shafts for
placing said shafts into and out of driving en
gagement one with the other, and including a
disk mounted on each shaft for rotation with its
respective shaft, a dog pivotally connected with 25
one of said disks, and the other of said disks be
ing provided with a notch for receiving the free
end of the dog, said permutation means acting to
normally retain the free end of the dog out of
engagement with said notch, and said permuta 30
tion means including cam means for raising the
free end of said dog out of engagement with said
notch and including a disk rotatable about one
of said shafts as an axis and provided with a cam
surface and a lug on said dog cooperable with 35
said cam surface, a slidably mounted operating
button for said cam disk, supporting means for
said button, and interengaging means on said
button and the cam-disk for rotating the latter
in a predetermined direction for e?ecting a rais
ing of the free end of the dog out of engagement
with said notch.
