l @ne of the essential` eatures et the inven'- QP tion is' thefirmly aiiixing of these doors in ,either the openor closedposition, such aixing bein-g automatically performed by the inechanisnr .Whichmay consist of a bracket 114k, car- Y ried by door 8 adjacent i-tshingedly supportdi@ ed edge.. Bracket. 1.44 includes a long: arml andi a short arm 18,y eachof Which preferably terminate inthesamefhorizontal plane. Upon Y Vdoor 6 ismounted fixture-20,;and bar ,QfQIinter-V .Connects the; free end oiliXture. 2()v and the. ex- 17e) tended end o'arm` 16 of bracket 1.4., For justment and ease of assembling, bar 22ris provided with a series of holes 24T'. formed through eaeh end .thereoiV A pin- 26 interconnects long armr 1.6. and one end ofbar. 22 as pin 2.8l likewise joinsfixture" 20 andthe opposite end ot bar 22;Y s

To perform the desired ,functiom a linik 30 essentially interconnects bar 22 and' arm; 18 `of bracket 14. One end of .link 30y ispivotal- .ly aiixedfas at 32,to.shortar1n.1 8 and-the: other end of link 30f is.. associated lWith bar v22 through. the intermediacy of slide 3ft. lt is to. this sli-de 34 that link 30is pivotallly joined by a connecterfl Which-allows movement .35 Whenthe mechanism isfoperated@ Connecter 36 might be passed: through. any` one of. Vholes 37 for the purpose of adjusting the effecting length. of link 30. 1 f

The construction just set tenth permits. .the 99 yieldable holding of doors (iI and 81 inthe closed position 4provided the connecter 36 joining link and Vslide 30` and. 8.4: respectively lies to' one side of aline. extending. between the vertical'hinge line ofhinges l2 supporting :95

door 6.andpin26;` That isto.say,jconnecter Y into the partsofvthe Inechanisrntohold-:doors19o n Y Y 6 and 8 in the closed position and movement on the partof door 6 is required before door 8 even starts to open. This movement extends only to an amount sufficient to draw connecter 36 to a line extending between hinge l2 and pin 26;

' From this pointon the.. doors'6 and 8 are freeV tomove and opening force need be exerted on but one of the doors. Link and -bar .22 will transmit opening power vtothe other 'door and when they have assumed the open position as shown in dotted lines of Fig. 1,j

the novel latching apparatus will automatically function to maintain the doors y:in this position until the means for actuating the 'latch to th'e'inop'erative `position is brought intoplay. One embodiment of thelatching l'zo . lso

mechanism contemplated by the invention *includes a yoke.38 rigid with barY 22 which rockingly'supports dog 40`through'the inter- -mediacy ofpintle 42.` A laterallyextending catch'44 may beform'ed on, or carriedas a part of, slide 34 and positionedto engage dog Vwhen doors V6 and 8 are opened.

As clearly shownin Fig. 4,'the inclined portion of dog 40 willride up and'over cateh44 toA a point where shoulderl 46 will rest'on lone l-sidev of catch 44 topreclude movement'in fone direction.l When dog 40 lhas moved to the positionjust mentioned, slide 34 will engage yok`e`38 and preclude'movement in the opposite direction.- Obviously, therefore, when doors 6 and 8 are openand slide 34 is in Y. )engagement with yoke 38 `and-dog 40 is restthe mechanism-will bev secured againstjrelativefmovem'ent. 1 l f i To allow doors 6 and' Sto be closed again it 'is but necessary to move dog`40'to a position 'ing by gravity upon catch 44, all members of where it is out of engagement withcatch 44.

'To do thiscable 48'is provided, 'one end `Yof which is attached to. adepending portion y50 #of dog 40, the other end of which hangs freely below.V slide 34, as illustrated in Fig. 2. Bar 22 is channel iron and cable 48 is'housed 'withiny 'this y'channel for aportion of:y its length. tie-pin 52 may be utilized to act ,as'a support'for'ca'ble 48 atthe point where it'i's vdesired tov have the same drop down.

The' upward movement of vdog 40: is limited by angled'surface54 which strikes the bottom ofjyoke 38iwhen cable,48 has moved dog p yout of engagement with catch 44.
