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 the key is rotated 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 It will be understood that in the use of the , claim and desire to secure by Letters Patent of. the United States is: ed and arranged as described above, the key is 1. A combined knob and concealed key unit 20 normally prevented from entering the slot 48 adapted to be mounted on a member provided since the latter is a narrow slot, that is only with a lockhaving a key-hole, said unit compris slightly wider than the thickness of the key, con ing a housing, a key mounted for movement in sequently, in order to enable the key to be pro said housing and into said key-hole for operating jected into operative engagement-with the lock, said lock,,and a knob for actuating said key, said 25 it is ?rst necessary to turn the knob 26 to bring knob being secured to said key and having a part the key into alignment with slot 48, that is with movable externally of said housing for operating the body of the key in vertical position when said the key and for concealing the latter from view. slot is a vertical slot. After the key has been 2.

As the resiliently opposing movement of said key into construction of the unit 20 is the same as that engagement therewith, and a knob for actuating hereinbefore described in reference to the desk said key, said knob being secured to said key and it, further description of said unit is unneces having a part movable externally of said housing 50 sary, and it will be understood also that the lock for operating the key and for concealing the latter combined knob and concealed key unit construct 20 25 3.0 45 per se may be of any conventional type or con struction. 55 In the form of the invention illustrated in Fig. 5 the unit 201) is shown attached to the outer sur face of drawer I 4 by fastening the housing 22b to the front of the drawer in any suitable manner as by screws ‘Ill. The knob 2% has a key 34b 60 ?xed thereto and movable therewith into oper ative engagement with lock 42b for projecting and retracting lock bolting 442). As in the con struction illustrated in Fig. 2, provision is made for spring-pressing knob 26?) and the key carried 65 thereby in a direction away from lock 42b. For this purpose, knob 26b‘ is provided with a cylin drical plunger or shank 3th engaged at its inner end by ?at springs 12. The inner end portion 58b‘ of the key is normally positioned in slot 481) 70 for guiding said key in its movement into and out of engagement with the lock. Thus it is seen that the constructions herein shown and described are well adapted to accom plish the several objects of the present invention.
