Referring to the drawings, my improved lock- ‘
ing mechanism comprises a barrel A adapted to
be secured within an opening in thev door of'a com- .-
An aim of the present invention is to provide an
improved lock of this character which is very sim
partment or the like; a spindle B journalled in
the barrel and adapted, when turned, to move the
ple in construction, compact in arrangement,
comparatively inexpensive to manufacture, which
‘an operating-member in the form of a knob D
may be readily assembled and installed, and which
may be very conveniently operated.
More particularly, an- aim of the invention is
locking bolt C into and out of effective position;
?xed upon the forward end of the spindle so that“ 110
when the knob is turned, the spindle is corre
spondingly turned to effect movement of the
to‘provide an improved keyless lock for comparté
ments and .the like and wherein the permutation
locking bolt; and a permutation locking mecha
mechanism is housed within the ‘operating mem
ber or knob by means of which the locking bolt
when the prevailing combination is disturbed, to
is moved into and out of effective position.
Other objects .Will be in part obvious and in
part pointed out more in detail hereinafter.
The inventionaccordingly consists in the fea
tures of construction, combination of elements
nism E located within the knob and adapted,
.
lock the knob and spindle against rotation with
respect to the barrel and, when the prevailing
combination is set up on the permutation wheels,
to permit rotation of the knob and spindle.
The barrel A has a longitudinal central bore.

in its forward face, an inclined groove 20 adapted
to receive a pin 2| projecting rearwardly from,
and disposed eccentrically with respect to the
axis of, the spindle B which is rotatably mounted
within the barrel. On the forward end of the
spindle is a head or plate 22, the rear face of
which is adapted to engage against the forward
face of the ?ange M of the barrel. This head
forms, in combination with the knob. or operating,
member D, a casing for housing the permutation
locking mechanism. The head has two latch re
ceiving openings 23 which are adapted to selec
tively register with the latch receiving recesses

in detail. In order to prevent longitudinal move
ment of the spindle within the barrel, and also
for the purpose of limiting the extent of rotation
of the spindle, the barrel has a circumferential
slot 25, and the spindle has a radially extend
ing pin 2'5 adapted to engage in this slot. To
permit of assembly of the spindle in the barrel,
this pin 25 is retractable into the spindle and, to
this end, the spindle has a radially extending re
10 cess 21 which accommodates an enlargement 28
on the inner end of the pin and a spring 29 be
hind this enlargement. The forward end of the
bore of the barrel is provided with longitudinally
extending grooves 35 spaced correspondingly to
the latch receiving recesses l8 and adapted to
receive a ball 36 located in a radial recess 3'!
in the spindle. The ball is normally urged out
wardly by a spring 38, this arrangement being
provided so that the spindle will be resiliently
20 held in each of its two extreme positions.
The knob D comprises a generally rectangular
box-like member open at its rear end so as to
receive the plate 22 on the forward end of the
spindle. The plate ?ts snugly within the rear
25 end of the knob and is secured in place therein
by means of screws 39 passing through openings
40 in the head and screwed into threaded re
cesses 4| provided in corner ?llets 42 in the knob.
The permutation mechanism is generally simi
30 lar to that described in my Patent No. 1,964,936
granted July 3rd, 1934. It comprises a plurality
of settable numeral wheels Gil suitably supported
on a shaft 8! which, in turn, is supported by the
side walls of the chassis or frame 62. Each per
35 mutation wheel has associated with it a concealed
lock controlling element here shown as being in
the form of a disk 63 cut away at one side as at
64. The peripheries of the permutation wheels
extend through slots 65 in the front wall of the
40 knob and are provided with suitable indicia such
as equally spaced numerals running from zero
(0) to nine (9). The peripheries of the permuta
tion wheels have spaced notches 66 which coop
erate with the free ends of the ?ngers 6? of a
45 detent 68 so that the wheels are frictionally held
in their various positions. The numeral ‘I0 desig
nates generally the locking bolt or latch adapted
to cooperate with the lock controlling elements
and arranged, when the prevailing combination
is disturbed, to extend through one of the open
ings 23 and engage in either one of two recesses
i8 depending on whether the locking bar is in
effective position or non-effective position.
The chassis, as shown in Fig. 6, is formed of
55 a plate of metal bent to channel shape, and this
chassis, as shown in Fig. 4——a, ?ts between the
corner ?llets 42 in the knob. The side walls of
the chassis have openings 15 for receiving the
shaft 6!, and the front wall of the chassis is
60 cut away so as to accommodate the permutation
wheels. The chassis is provided with notches 16
for the reception of lugs Ti extending from the
anchored end of the detent 6B. The side walls
of the chassis at their lower ends are provided
65 with recesses 80, the crotches 81 of which con
stitute fulcrums for the latch ‘iii. Extending for
wardly from these recesses are notches 82 adapt
ed to receive the ends of a spring 83 by means of
which the latch is normally urged against the
70 lock controlling elements and towards its effec
tive position.
The latch ‘ill, as will be seen most clearly from
Fig. 8, comprises a stamping having a cross mem
ber 85 at its pivoted end, a cross member 86 at
75 its free end, and longitudinally extending mem
bers 81 which straddle the central permutation
wheel and engage the peripheries of the lock
controlling elements. The cross member 85 has
laterally extending lugs 88 engaging the fulcrums
8i of the chassis and it also has a centrally lo
cated ear 89 adapted to be received by the cen
trally disposed loops 96 of the spring 83. Extend
ing rearwardly from the free end of the latch 18
and disposed generally at right angles to the
length of the latch is a locking lug 9i which 10
is adapted to project through one of the open
ings 23 in the head of the spindle and into the
recesses IS in the ?ange of the barrel when the
parts are in locking position. The particular re
cesses in which the lug 9| engages will depend 15
upon the direction of movement of the locking
bolt into locking position in any particular in
stallation. In Figs. 2 and 3‘ of the drawings, the
lock is shown as being installed adjacent the up
per free edge of the door I3, and the bolt C is 20
illustrated as being movable vertically upwardly
into locking position, and with such an installa
tion, the locking lug extends through the upper
most opening 23 and engages in the uppermost
recess I8 shown in Fig. 10 when the bolt C is in 25
locking position and the prevailing combination
is disturbed. If, now, the combination is set up
on the wheels and the spindle is turned counter
clockwise to withdraw the locking bolt, the up
per opening 23 will be brought into registry with 30
the left hand recess 18 shown in Fig. 10, and if
the combination is now disturbed, the latch will
extend into that recess. In the event that the
lock is installed on a door hinged at the right,
and in which event the bolt should be horizon 35
tally disposed and moved into locking position
towards the left. the bolt would be reversed end
for end within the slot II, and the barrel would
be installed in an angular position at
right shown in Fig. 10 so that the
recess l8 shown in that ?gure would
top. In the event that the bolt was to
90° to the
left hand ~40
be at the
be thrown
downwardly into locking position or to the right
into locking position, the knob with the permu
tation mechanism therein would be removed
from the spindle head and then replaced thereon
in a reverse position to that shown in the draw
ings, and the other opening 23 and the other two
recesses l8 would accommodate the locking lug.
For the purpose of permitting the combination 50
to be readily changed, the shaft BI is mounted
for sliding movement and carries a head 95 pro
vided with a lug or ?nger piece 96 which is
adapted to extend through either one of the L
shaped openings 91 in the head 22 depending“ 55
upon the position in which the knob is assembled
on the head. The spring 98 normally urges the
shaft to operative position. Each lock control
ling member has associated with it a hub 99 and
each hub has splines or ribs I99 on its periphery.
Each permutation wheel has a central opening
provided with grooves adapted to. receive the ribs
I00 on a respective hub.
To change the com
bination, it is merely necessary to push the shaft
to the left, referring to Fig. 4—a, to thereby dis-> 65
engage the ribs from the wheels; then turn the
wheels to the desired combination, and ?nally
release the shaft. In order to prevent surrepti
tious or careless operation of the combination
change means, while the latch is in locking po 70
sition, the bar 85 of the latch 10 is provided
with a ?nger i0! adapted to cooperate with the
head 95. When the latch is in looking position,
this ?nger engages‘behind the head so that the
shaft cannot be moved to the right, reference be-* 175
‘2,1 19,704
ing had to Fig. 4—a. When the latch isin the
non-locking position shown in Fig.3, the ?nger
is out of the path of movement of‘ the head so
that a change in the combination may be vef
fected.
It will be seen from the foregoing description,
taken in connection with the accompanying
drawings, that there is provided in accordance
with the present invention an improved keyless
10 lock which may be very easily installed and con
veniently operated. When it is desired to install
the lock, it is merely necessary to provide a round
hble l2 of the require diameter in the door; in
sert the barrel into position in the opening and
15 then clamp it in place by the nut I6; position the
locking bolt C in the slot I! of the barrel, and
then-with the pin 26 pushed into the spindle in
sert the spindle into the barrel. When the spin
dle is slid into ?nal position, the eccentric pin
20 2| will engage in the slot of the locking bolt and
the stop pin 25 will engage in the circumferen
tial slot 25 of the barrel. Should it be desired to
change the combination at any time, the spindle
and knob are removed from the barrel so that the
25 ?nger piece 96 will be readily accessible.
The
spindle and knob may be easily removed from the
barrel by merely pressing the stop pin 26 into
the spindle and then pulling on the knob. The
installed lock may be very easily and conven
30 iently operated. In Fig. 3, the bolt is shown as
being in locking position, and the latch is illus
trated by full lines as being in non-effective po
sition, the prevailing combination having been
set up on the permutation wheels. To move the
35 bolt to non-e?ective position, it is merely neces
sary to give the knob a quarter of a turn counter
clockwise. To secure the door in closed position,
the knob is given a quarter turn clockwise, there
by moving the bolt to locking position, and then
40 the prevailing combination is disturbed, thereby
moving the latch '10 to the effective position
shown by dotted lines in Fig. 3.
As many changes could be made in the above
construction and many apparently widely differ
45 ent embodiments of this invention could be made
without departing from the scope thereof, it is
intended that all matter contained in the above
description or shown in the accompanying draw
ings shall be interpreted as illustrative and not.
50 in a limiting sense.
