Locking member 79 is moved upwardly and downwardly on the door j amb by a lever 8lentering a slot 85 of a plate 86 fastened to the slide 79, and pivoted at 86 in a recess 87 of the rib 7 6. As the lever is swung up` Wardly, it engages the plate 86 andcarries the locking member 79 1n the same direction; and depression of the lever lowers said v' member to locking position, the lug 82 then resting upon the cabinet base.

The end face of door frame 78 (Fig. 12) has recesses 88 receiving the tongues 81, and slots 89 extendingv downwardly vtherefrom in which the tongues engage When the slide is Vmoved to llocking position, in Vthe same manner as previously described. Similarly,

3. In a cabinet having a hinged door closing against a stationary door jamb, loclring mechanism for securing the closed door, comprising a locking member mounted tor longitudinal sliding movement on the door jamb and having a plurality of locking tongues spaced longitudinally vwith respect to the j amb and projecting toward the end face of the door traine, said end face having complemental recesses receiving said tongues in locking engagement, said leclting member ei:- tendino' approximately to one end of the Vjamb and having an inwardly projecting lug at its said end, an auxiliary locking element slidable horizontally ofthe door frame and en gaging said lug to hold said member in lool*- ing position, a lever pivoted to the door j amb for operating the locking member, and an eccentric mounted on the door frame for sliding said auxiliary lool-zing element.

l. In a cabinet having a hinged door clesing against a stationary door jamb, locking mechanism for securing the closed door, comprising a locking member slidable longitudinally of the door amb and having a projecting tongue intermediate its end face and a lug adjacent one'of its ends, the end tace of theY door having a recess receiving said tongue in locking engagement, means for sliding said member to eiiiect said engagement, and an auxiliary locking bolt slidably mounted on the door frame and engageable with said lug to hold said tongue in locking position.

5. ln a cabinet having a hinged door closing against a stationary door jamb, locking mechanism for securing the closed door, comprising a locking member slidable loi-igitudinally of the door amb and having a projectingtongue intermediate its ends and a lug adjacent one of its ends, the end face of the door having a recess receiving said tongue in loclring engagement, means for sliding said member to eliect said engagement, an auxiliary locking bolt slidable ho izontally et the door trame and engageable with Vsaid lug to hold said tongue in locking position, an eccentric t'or sliding the bolt in opposite direction, and a key-operated lock for Vrotating the eccentric.

6. In a cabinet having panels provided with marginal trames, one ot the panels being hinged to provide a door closing against a door j amb formed by the vertical frame of an adjacent panel, and said amb having a longitudinal channel therein, locking mechanism for securing the closed door, comprising a locking bari'itting said channel and slidable longitudinally therein, said bar having its outer face substantially flush with the tace of the jamb and having a locking tongue projecting outwardly therefrom, the end h face of the vertical frame of the door having an edge recessv adapted to receive said tongue and having a slot for holding the tongue in locking engagement, and a lever tor operating the said bar to eliect said engagement.

. 7. In a cabinet having panels provided with marginal trames, one ot the panels being hinged to provide a door closing against a door jamb formed by the vertical trame of an adjacent panel, and said j amb having a longitudinal channel therein, locking mechanism for securing the closed door, comprising a locking member slidable longitudinally Within said channel and having a locking tongue projecting outwardly therefrom, the end 'face ot the vertical trame of the door having a recess adapted to receive said tongue in loclting engagement, a lever for operating said member to effect said engagement, and auxiliary locking means mounted upon the inner sideof a horizontal frame of the door and comprising a bolt movable longitudinally of said rameand adapted to engage said memci c ber to hold the tongue in locking position.

8. In a cabinet having panels provided with marginal frames, two of the panels being hinged to provide doors closing against a common door amb, the jamb having a verti ally extending rib, locking mechanism for securing the closed doors, comprising a locking member slid ble longitudinally upon said rib and having locking tongues on its opposite sides, the end faces of the respective doors having con'iplementaiV recesses receiving said tongues in locking engagement, and auxiliary locking means carried by one of said doors and adapted to engage said member to hold the tongues in locking position.
