FURNITURE DRAWER LOCK Filed Nov, 2, 1959 ATTORNEY.

Patented Feb. 17, 1942 ics 2,273,151` FURNITURE DRAWER Loon James c. siegel, New York., N. Y. Applicationv November 2, 1939,. SerialIN. '3023514` 7: claims. (01.45-94) This invention relates to drawer-locking. mechanism of the: type described in. my Patent No. 2,182,504, issued December 5, 1939,. for a Furniture: drawerV lock.

As i's. explainedin ther said patent,.drawer l'ock ing mechanism' for locking. simultaneously ra group of` drawers in an article of' furniture, has forv many years been considered. desiralc'zle.v Because furniture equipped with drawers is. made by` many different manufacturers, and' because each manufacturer may have manyY diiferent sty-les and sizes, it has been impossible: heretofore to equip furniture with locking mechanism, unless-this locking mechanism was especiallyl designed for eachv particular styles of. furniturel and for each particular size thereof'. Naturally., such specially designed locking mechanismy was high in cost and not available'for popular priced furniture. Mypatent discloses locking. mechanism for furniturev whichl may.V be manufactured in largeY quantities and, readily applied to furniture of many different styles andy sizes.. Because: of this. adaptation of my inventiony to furniture manufactured under. modern systems of mass production, my. inventiony has. attained considerable commercial,A success.

The invention disclosed and. claimed by mein thisY application is an improvement on that shown in my patent sup-ra. In this application, Ifshall show devices. which facilitate further. the installation of locking mechanism in furniture of' diiferentY styles and different sizes.

For a description of my invention, Ishall refer to Fig..` 1 which. shows the back ofa piece of furniture equipped' with sliding drawers. Fig. 2 is a perspective view of a bracket utilized in Fig. 1. Fig. 3 is a view showing the assembly of the bracket to a locking bar. Fig. 4 is'a view looking down on one of the drawer locking hooks, while Fig. 5 is a perspective View of a locking hook.

Referring now more particularly to the drawing, reference numeral I indicates part of an article of furniture such as a bureau, desk, chiffonier, etc., having drawers II and I2 supported and separated by partitions I3 and I4. The locking mechanism of my invention includes a locking bar assembly I which comprises a horizontal arm I6 and a vertical arm I'I connected by a reinforcing angular bar I8.

A locking cylinder of the type shown in my patent supra, the construction of which is well known in the art, is designated by reference numeral I9, and an extension 20 thereof is secured as at 2| to the horizontal arm I6. The vertical 5.3 applied.

arm I1' operates in slots- 22 ofthe partitions I3 and I`4, as isY best seen. in` Fig. 4, and is maintained in the said slots by' metal plates 23 held ink place by screws 2'4'.

A unique type of bracket 2.5,. shown best in Figs. 2 and 3, is utilized byr me for supporting for sliding movement the locking bar I5 through cooperation with the horizontal arm IE thereof. The bracket 25 is equipped with a bearing portion 25 having aconstricted entrance defined by surfaces. 21- andr 28. In applying the locking mechanism to an article of furniture, the horizontal arm I6 is'rst inserted into each of the bearing slots 26 of a suitable number o-f brackets. Once inserted into the bearing slots, in a Ina-n'- ner illustratedr best inV Fig. 3, arm I6 is main@- tained. in those bearing slots for sliding move ment-ina. plane juxtaposed to the backs of the several drawers- The brackets 25` are suitably secured; asl illustratedI on the partition I-3', in positions best suited.Y for the` particular instal-lation. It isy only bymanipulation of .arm I6rela tively to the brackets 25, opposite. to that in as' sembling arm I6 to the brackets illustrated-in Fig. 3, that it is possible tomovev arm I6.Y out of the severa-l: bracket slots.

For locking. each of the drawers, IA utilize a hook 29, shown. best. in. Figs. 4.- and` 5, this hook being secured in. Fig. 4 tothe. drawer I2. Itis readily seen that. when` the locking bar I5 is movedl to the right from theV position of Fig.- 15. the vertical. arm. IJ will move into lockingt relation. with hooks 2.9 to prevent outward Inovementof thedrawers II and I-2.

It is well' to note that the reinforcingbar I8 of the locking bar assembly is spring actuated by a spring 30 relatively to one of the brackets 25 through the fastening of the end of the spring 30 to the small bore 3| in the bracket 25. When the l-ocking cylinder is operated to release the locking bar assembly I5, the spring 30 will move the bar to the left and to the release position of Fig. 1.

Considering now the invention in its entirety, it is readily perceived that a manufacturer wishing to apply my mechanism to his furniture, may do so by buying a suitable number of brackets 25, hooks 24, and plates 23. By merely notching the partitions of his furniture so as to apply the plates 23 thereto, and by securing the brackets 25 `and hooks II in any particular position which he may desire, he may readily assemble the entire locking mechanism in a very few minutes. Cylinder lock I9 is, of course, quite easily Those skilled in the art will now appreciate that through the contribution which I have made and herein described, the application of my locking mechanism to an article of furniture is great- 1y facilitated, and that the application of the locking mechanism may be made to practically any article of furniture without the manufacture of special parts of special size.

I now claim:

1. In a combination of the class described, a cabinet housing having a series of sliding drawers, partitions between said drawers, a series of brackets supported on one of said partitions, each of said brackets having a bearing slot internally thereof and a constricted entrance into said bearing slot, a locking bar havinga horizontal arm, said horizontal arm entering said bearing slots through said constricted entrances and thereafter maintained in said bearing slots for horizontal sliding movement, the plane of said sliding movement being juxtaposed to the plane kof' the backs of said drawers, means whereby said bar locks said drawers in one position of said bar, and means for locking said bar against movement from said one position.

2. In a combination of the class described, a cabinet housing having a series of sliding drawers, partitions between said drawers, a series of brackets having flanges whereby to be secured on one of said partitions with a portion of each of said brackets extending vertically from said partition, each of said bracket portions having a bearing slot internally thereof and a constricted entrance into said bearing slot, a locking bar having a horizontal arm, said horizontal arm entering said bearing slots through said constricted entrances and thereafter maintained in said bearing slots for horizontal sliding movement, the plane of said sliding movement being juxtaposed to the plane of the backs of said drawers, means whereby said bar locks said drawers in one position of said bar, and means for locking said bar against movement from said one position.
