Patented Oct, V21, 1930 feminins r. HJAMES, orciios Aucuns, enitrroiaivin` j f t REMOTE-jcoi'rnomnn Dinan/inn Application mea october 1, 192,9.y semi No. 396,592.

invention relates toVl a remote controlled drawerand hasfor its primary object the yprovision of avmechanism by which a vnumber of different` drawers at variousv .I places may be simultaneously closed and docked, or locked if already closed7 byoperl' ating a switch which may be located remote fro'rnsome or all'ofthe drawers Other objects include the provision of such a mecha# lo'nismiwhich will not interfere with'the unlocking or locking and opening orf/closing of any or allot the drawers in theusualv manner and onewhich will be simple, strong and reliable.

"15. 4These objects together with other objectsy andcorresponding accomplishments are obtained by means of-the embodiment of my Vinvention illustrated in the accompanying drawing in whichi.

Y Fig.` 1 is a cross'section through a` counter H "having the usual type of drawer secured to j its underside andwlitted with my closing mechanism;`Figs. 2'an`d 3 are sections as seen on correspondinglynumbered lines of Fig. 1;Fig.y l isa fragmentary-view similar to Fig. 1 but showing the drawer in open position, and Fig. 5 is a diagrammaticvview showing operating switches connectedto a Vplurality of drawer closing mechanisms.

30 7 As illustrative of the invention7 Iv have shown the .drawer embodiedi'n a cabinetior counter, although it maybelocatedlin vari- Vous other places. Referring with more particularity to the drawings 9 generally indi cates a cabinet or closed compartment,'the

1 top 100i? which maybe a portion of a counter. Slidably supported in vany desired manner on the side `walls 11 of the compartment is a: conventional drawer 12. Attached 4to the 40 underside of the drawer'is a lrack 14 and a keeper 15 gthese will be morefully described later. Secured to the underside of counter `10 nearthe outside end of the drawer is a stop member 16 and dogs 17 tocoact there .45 withare secured'to the sides of the drawer. 'j j Y `Eachfof these comprises'atooth'ed member l 17?l pivotally mounted on the side vof the drawer and urged upwardly lby ,a compressionvspring`17c against a stop 17b fixedto 5,0 the side ofthevdrawer.- lThe .dogsnormally limit the outward movement vof the ldrawer .by engaging stop 16', but when itfis desired Vto pull the drawer farther outthey'may' be manually y, depressed against' the Ispringsl so as to ride under the stop. The inclined sur'- 55 Vface. on the back of the toothedmember will enable it to be forced down under the-.stop j when the draweris pushed in,` permittingv f-the drawer to .be closed'readily. J Y.

Secured to thefront wallo'f the compart- 60 j ment is a spring'lock 19,v which may be actuated by inserting a keyV 2O therein. f: Thevlock is mounted so that the bolt 21 is :projectable downwardly, and is lof conventionalV form except for having a vtail Vor extension22 se- 65 cured to thel upper end of thebolt.k Alink 23 is pivoted to this Vextension and'supports V"at its upper end aflatch member. 24 pivoted in afprotective casing securedl to the yfront wall of" the compartment.v The latch niem- 70 ber 211 has 1an upwardly projecting tooth 24a and a counterweightl arm 24h. The arrangement is so balanced that `the counterweight normallyv urges the latch upwardly where it 'may engage keeper 15, the movement of the 75 counterweight arm being limited by link 23.

'When the bolt is retractedby turning key 20, link 23 raises the counterweight arm and lowers 24a out Vof the way of keeperl.

Extension y22 'which is preferably v'of 8O metal and an electric conductor and vhas a projection 22a on one side witha piece of insulatingf material 25 secured in its upper.: portiong Adj aeent thereto'V and suitably supported on: the Vfront of the compartment, as lin a y bakelite blockare spring lfingersl 26aand 2,6b

2) finger .26 is in Contact with the insulation 90 25 andno current'can f iow. When the bolt is Y e raised. and the drawer is unlocked, bothfin-V gers are in contact with'the metal portion of extension 22a so that current 'can How between them in effect closing the switch.l 95

A shaft 28 'extending transversely of com- Vpa'rtment 9 is -rotatably mounted inbearings 29 and has al worm Vwheel, 30fsejcured to Lit.: Aworm 31 engagesthis worm wheel and is mounted ona shaft -kdrivenby means being connected to said trip lever and arranged to release said bolt, and an auxiliary switch operated by said lock and armotor and the source of current when said bolt is in drawer locking position. l

` 4. A closing mechanism for a drawer 'comprising an electriccircuit including a motor,

a control switch for connecting saidfmotor.;k

with a source of current, a freely journalled` lsegmental gear, a one-way drivepmeans for connecting said motor Vtosaid gear so as to drive the latter, a drawer slidably mounted Ladjacent said gear and having a'rack secured to 1t arranged to be engaged by said gear upon rotation thereof, outward ltravel limiting means secured to said drawer, an overbalance arm attachedto said gear, a trip lever arranged'to be actuated by'said arm upon rotaf tion of said gear, a spring loclzfhavinga bolt normally7 tending to lock said drawer y1n closed position, a restrainingv rod disposed tovhold said bolt in drawer unlockingpositicn, said rod being connected to said triplever and arranged to be moved to release said bolt,.and

i an auxiliary switchy operated by'isaid lock and arranged to interrupt the circuitbetween said motor and the lsource of current when said `bolt .is in drawer locking position.`

5. A closing mechanism for a drawer comprising a motor and a source of current, acontrol switch for connecting said motor with said source of current, -a shaft andloverbalanced segmental gear rotatably mounted on said shaft, said shaft being arranged to be driven by said motor, means secured to said shaft adapted to engage said gearand cause lsaid gear to be'rotated with said shaft, a trip actuating arm attached tosaid gear, a drawer slidably mounted adjacent said gear land having a rack secured to it arranged to be engaged by said gear upon rotation thereof, a spring lock having av bolt normallytending to 'lock said drawer in closed position, restraining mechanisml for holding said bolt in vdrawer unlocking position, said restraining mechanism being operated by said arm, and

arranged torelease said bolt, an auxiliary switch operated by said lock and arranged to interrupt the circuit between saidfmotor drawer locking position.

and source vof current when vsaid' bolt is inarm upon rotation of said gear, a lock havj ing a bolt normally tending.A to lock said ranged to interrupt the circuit between said drawer in closedposition, restraining means locking position, said restraining means bei prising a motor and a sourceof current, a

masterfcontrol Vswitch for connecting said motor with said source of current, a segmental gear rotatably mounted on said shaft, said l shaft being arranged tobe driven by'said motor, means secured to said shaft adapted to engage said gear and cause said gear to be rotated with said shaft, an overbalance arm attached to said gear whereby to cause the gear to revolve on said shaft to a predetermined point, a drawer slidably mounted adjacent said gear and having a rack secured to it arranged to be engaged by said gear :upon rotation thereof, a trip lever arranged to be actuatedrby said arm upon rotation of said gear, a spring lock having a bolt normally tending to lock said drawer in closed position, a restraining rod disposed to hold said bolt in drawer unlocking position, said rod being connected'to said trip lever and arranged to be moved to release said bolt, and an auxiliary switch operated by said lock and arranged tol vdrawer locking position.

In witness that I claim the foregoing I have hereunto' subscribed my name this 25th day of September, 1929.
