ATo all 'whom it may concern? Be it known thatl ll, BRYANT W. CLAUsoN, a citizen Aof the United States, and resident of Rexford, in the county\of Thomas and State of Kansas, have invented certain new and useful improvements in Electrical Drawer-Locks, of which the following is a specification.
This invention relates to furniture and has more particular reference to an improved drawer lock for desks and like articles.
The invention has for its dominantobject to provide an electrically operated drawer lock whereby certain or all of the drawers of the desk can be automatically locked in their closed positions without the use of levers, springA catches or similar devices.
llt yis also an object of the invention to provide means for automatically moving the drawers to open positions, immediately sub1 se uent to the unlocking of the same.4
ther and further improvements and novel details in the construction and arrangement of parts will be appreciated from v through the medium the description to follow, which for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part hereof and wherein the preferred embodiment of the invention is shown for y.the purpose of illustration.
lin the drawings:
Figure l is a fraentary vertical longitudinal section through a desk with my improved electrically operated lock applied thereto;
llig. 2 is a fraental end elevation thereof,"
lBig. 3 is a detail in perspective of the i electrically operated locking bolt;
liig.4 is a diagraatic view showing the wiring of the electrically operated bolts; and
llig. 5 is a detail in elevation of the im-` proved circuit closing means for energizing the various electrically operated bolts.
Referring now more specihcally to the several hgures of the said drawings and in connection with which like reference characters will designate corresponding parts, there is shown a usual oce desk indicated 'ts entirety y the numeral l and having at d therein in proximity of the opposite sldes of the same, a plurality of longitwally dissed supporting bars desigof the same are then extended nated 2, the opposite extremities of which are engaged -with similar transversely disposed bars 3, whereby the various drawers 4 of the desk will be slidably supported therein. lt is to be noted, in this connection that the drawers 4 are of a length slightly less than the length of the desk 1 and as a consequence," a Achamber for' receiving the electrically operated lock, which will be subsequently described, is provided.
Upon the rear transversely disposed sup` porting bars 3, magnetsy 5 are secured of suitable straps or like connections, while to the opposite sides of the drawer compartments of the said desk, apertured guide bars 6 are secured. Bolts 7 are slidably received through the openings formed in the guide bars 6 and carry upon their upper extremities armatures 8, adapted to be attracted, at times, by the poles of their respective magnets 5. To the rear ends of each of the drawers 47 keepers 9 are adlxed, as at l0 and are so positioned as vto receive the lower `extremities of the slidable bolt 7 therein. Contractile coiled springs 11 are secured to the lower faces of the rear end of the drawers 4 and the forward transversely supporting bars 3 of the desk and obviously, serve as means for automatically moving the said drawers to open position immediately subsequent to the disengaging of the locking means therefrom.
lln Fig. 4, there is shown a diagrammatic view of the method f wiring the various magnets 5 whereby the same may be independently energized to actuate their respective armatures 8 and the slidable bolts 7 carried thereby. Main wires a are engaged with the opposite poles of a suitable source of electrical energy b, one end of one of the wires being engaged with the contact point of a spring switch arm c while the other is engaged with a plurality or series of branch wires designated ai'. ln these branch wires 0l', the magnets 5 are interposed and the remaining or free extremities into engagepoints c of to be noted, is formed of spring ment with the various contact the circuit closing switch. llt is that the switch arm metal and, as shown in Fig. 5 is normally maintained in spaced relation from the various contact points c. Thus, when itis desired to close any one of the magnetic energizin circuits, the arm must be depressed in order that it ithe desired point. By this means, movement of the switch arm to the desired position previous to the closing of the selected magnetl energizing circuit 1s permitted. v
In operation, when it is desired to release certain of the slidable drawers'f, the proper magnets 5 are energized, thereby drawlng the slidable locking bolts 7 together with the armature plates 8 into engagement therewith. Obviously, upon disengagement of the bolt 7 from its respective keeper 9, the
articular drawer as locked thereby will be mstantly moved to open position due to the engagement of the contractile spring 11 therewith. The drawer may be readily closed, since, the locking bolt 7, due to its engagement with the electro-magnets 5 is out of the path of travel of the keeper 9.
a plurality of magnets supported adjacent mesme.
- adjacent ends of said drawers for receiving the bolts therein, at times, means for independently energizing `the magnets, and means engaged with the forward portions of said article and the various drawers for imparting movement thereto subsequent to the releasing of the bolts.
2. The combination with an article of lfurniture and the slidable drawers thereof,
of a plurality of electro-magnets supported adjacent the rear portion of the article, apertured guide bars arranged in proximity of said electro-magnets, slidable bolts received by the guide bars and having armature plates arranged on their upper ends, keepers carried on the adjacent ends of said drawersfor receiving the bolts therein, at times, means for independently energizing the 'electromagnets, and a plurality of contractile springs-engaged with the forward portions of said article and the various drawers for moving the same to open position subsequent to the releasin of the bolts.
In testimony whereof, I a x my signa ture hereto.l
