DRAWER LOCK MECHANISM Filed Oct. 22. 1928 INVENTOR 'i Patented 3, 1931" 7 foam; E. mnnnwirz, or GRAND man m msm DRAWER LocxivmcnnNISM imam filed umber-a2, 1923.] semi Na. 313,977.
The main objects of this inventionare:
First, to -provide an improved locking means for desk-drawers or, for a series: of
' "drawers which is actuated to locking position a from an actuating'drawenthe locking means I being returnedto its-open position by gravity.
' when the actuating drawer isunlocked or re- "leased; ;f
Second, to providev an improved drawer In locking means of the class'describedwhichis 'very simple in its structure and has the parts arranged so thatitmay be quickly'mounted fin a desk structure; V l i j Objects pertaining to detailsand-economies 1.; of my inventiohflwi'll appear from [thede fscription to follow. The invention is defined in th'e'claims p A structure which apreiferred embodif ment of my invention isclearly illustrated 1n 7 -f the accompanying drawingsin which Fig. "1' is a fragmentary view mainly in vertical section on aline corresponding to line 1-11of Fig. 3, parts being broken away to better show structural details. 1 I i as Fig. 2 is a fragmentary vertical section on line 22 of Fig.3;
Fig. 31s a horizontal section 01; line 3-3 of Figs'land 2. I r
Fig. 4: is a perspective view of the-locking V mechanism removed from the desk. M H
o Referring to the drawings,the structure il-. lustrated is an-office desk ofthe typeinwhich V I have embodied my improvements and. in general, comprises a suitable cabinet desigm hated by the numeral 1 and provided with a J series'ofdrawers 2,3'and et'arranged vertical- 1y. Thecentral drawer of the desk is shown "at 5; this arrangement'being commonloflice desk arrangement.
:4 The drawer is p'ibvid a with a is. or
. j other means for'retaining it in closed posi tionfshown conventionally at 6. At the rear of the seriesof drawersI'mount a locking bar 7 for vertical reciprocating movement, a
pair of b-rackets B'being secured to the desk "frame and provided with projecting studs 9 engaging thelong iftudinal slots 10 in the lock- 'in'gbar. I l

airbase a. ml-ans, of the series f. drawers as is-illustrated Fig. 1. The
' weight; of thelocking bar and its attached partsis such as to return the locking bar ;to'
unlocking position when its actuating means i sreleased; 7
-An;actuating lever 12ispiv0ted at 13 at the rear of the drawer 5 with its downwardly projecting arm 14 in position to be engaged y the drawerv 5 when it isc ompletely closed. The arm151of the actuatinglever' engages an arm l6-projecting laterally fromqthe lock-. ingi bar-so that thelocking'baris lifted to locking position when'the drawer 5is fully closed;orzin the;position indicated by dotted My 'improved locking mechanism is very simple andie'conomic'al in its parts and at the same-timej.-they..are strong and durable, no springsbeing required to move the parts to unlocking position; "The spring arm of the actuating;leverixyields, however, to permit closing of the drawers afterthe locking bar hasfbeen actuated as described.
I have illustrated and described my improvements in an adaptation which is suitablefor types of desks which are very extensively used. Other adaptations for par- ;ticular designs of desks will, it is believed,
