LOCKING AND LATCHING MEANS
Arthur M; Bier, New York, N. Y. ‘
Application March 5, 1938, Serial No. 194,032
8 Claims. (Cl. 70-431)
The present invention relates to means for
looking or latching furniture drawers, cabinet
and other doors or closures, etc.
One object of the invention is to provide a lock
5 or latch of the character described which is con
cealed from view so that unauthorized persons,
unfamiliar with the construction and operation
of the lock or latch cannot readily see or ob
tain access to the drawer‘ or cabinet equipped
O
therewith.
‘
‘
Another object of the invention is to provide
a combined knob and concealed key unit' con
structed and arranged to be mounted on a drawer,
door, or other movable or stationary member
15. or part of furniture, ?ling cabinets, wardrobes,
etc., provided with a lock therefor in such a man
ner that the outer surfaces of the drawers or
doors of such furniture or the like are devoid
of visible keyholes or the like. ' This is considered
20 a desirable feature of the invention, particular
ly when the latter is applied to ?ne or decora
tive furniture, as it is possible to lock‘the drawers,
doors, or other parts of such furniture without
marring the appearance thereof by the provision
25 of keyholes or similar openings. Furthermore,
this eliminates the possibility of scratching or
scraping of the paint, varnish or lacquer by the
key, and also the possibility of losing or mislay
ing the key.
The present invention is intended primarily for
looking or latching the drawers, doors or other
parts of various articles of home, office and other
furniture to insure privacy and protection. against
pilferé'rs and against curious and unauthorized
35 individuals.
The above objects of the invention and other
objects which might hereinafter appear will best
be understood from the following description
considered in‘ reference to the accompanying
49. drawing forming a part of the present speci?ca
tion.
In the drawing:
,
Fig. 1 is a fragmentary perspective view of
1 desk embodying the present invention;
45,
Fig. 2 is‘ a sectional view on the line 2-2 of
Fig. 1, parts being shown in elevation;
Fig. 3 is a sectional view on the line 3-—3 of
Fig. 2;
Fig. 4 is a perspective View of trunk or chest
50 embodying the invention;
Fig. 5 is a view similar to Fig. 2 showing an
other form of the invention.
Referring now to the drawing in detail, the
unit embodying the present invention is illus
55, trated as applied to a desk I0 and more particu
larly to the drawers [2, l4, l6 and I8 of said
desk. Each unit is designated generally by the
reference numeral 20 and as its manner of at
tachment and relation to the lock of each drawer
is substantially the same, and as each unit may "5
be of the same construction, only one of said
units and the relation thereof to the drawer on
which it is mounted will be described.
Referring now more particularly to Fig. 2 of
the drawing, the unit 2!! is shown mounted on 10
the drawer I 4 and is seen to comprise a dome
or housing 22 secured within a recess 24 in said
drawer. Said housing may be secured in posi
tion in any suitable way, as by being glued in
said recess. A knob 26 is mounted for slidable 15
and rotary movement in housing 22. More
speci?cally, the head 28 of said knob is provided
with a shank 3B which projects through an end
opening 32 in said housing and is mounted in
the latter for sliding and turning movement. A 20
key 34 is ?xed to and carried by knob 26, and
for this purpose, the knob shank 3!) is provided
with a recess 36 in which the outer end portion
38 of the key is ?xed. Key 34 may be secured
to shank 30 by forcing portion 38 into recess 36 25
and, if desired, a fastening pin or rivet 40 pass
ing through key portion 38 and shank 30 may be
utilized for more securely fastening the key to
the knob. As shown, the knob and key unit is
mounted on drawer H1 in juxtaposition to the 30
lock 42 which may be of any suitable construc
tion, being here shown as a conventional desk
drawer lock provided with the usual locking bolt
or latch 44. Key 34 is movable into and out of
engagement with lock #52 in an opening lit in the 35,
desk drawer and through a vertical key~ho1e slot
48 in the lock casing 42. Said key has a projec
tion 50 at its inner
gages slot 48 being

portion of the key
end which permanently én
rotatable in said slot when
to align the lock operating 40
with vertical slot 188. Thus
the knob and key unit has a bearing at longi
tudinally spaced points adjacent the inner and
outer ends thereof, that is in the slot 48 and in
the opening 32 of housing 22, whereby said unit 45.
is prevented from moving out of alignment in
relation to lock 42.
In the unit as shown, the construction is pref
erably such that the key is normally spring
pressed out of operative engagement with lock- 50:
42.
For this purpose there is provided a coiled
spring 52 surrounding the key.
The inner end
54 of said spring bears against and is secured to
a stationary disk 56, ?xed at the inner end of
housing 22. The opposite end 58 of spring 52 559
2,129,810
bears against and is secured to a movable disk
60 which is large enough to abut against the
inner housing portion 62 adjacent opening 32,
thereby to limit the outward movement of the key
and the knob secured thereto.
Also, as here
shown, the key is provided with side projections
64 which engage the inner surface of disk 60 for
preventing withdrawal of the key from the hous
ing. However, said side projections may be
10 omitted as the disk 60 may be ?xed to the shank
38 of the knob as will readily be understood with
out further illustration.‘ By virtue of the con
struction just described, the spring acts on the
key and knob to project the same out of operative
15 engagement with lock 42 and resiliently opposes‘
the movement of the knob and the key to oper
ative engagement with the lock.
'
invention, it will be understood that the latter
may be embodied otherwise than as here shown
and that in the constructions herein shown or
described, certain changes in the design and ar
rangement of the parts may be made and will oc
cur to skilled artisans in view of the present de
scription. The housing 22 and the knob 26 may
be made of any suitable material but said parts
are preferably made of wood thereby to match
the desk or other article when the latter is, as 10
usual, made of wood, although if desired, the
housing or knob or both may be made of metal.
Therefore, I do not wish to be limited precisely
to the present forms of the invention or to any
of them except as may be required by the ap 15
pended claims.
Having thus described my invention, what I
