A keeper 5S is mounted on the Wall l1 adjacent the free edge ol the door and comprises a plate 59 apertured to receive screws or other fastening means Gt) and mounting the keeper in a vertical position and in alinement With the easing proper as heretofore described.

ln the operation olf the device. when the door is closed and the holt or latch il is projected by the spring; 22, the trip end ll is seated in the recess 32 aeainat' the shoulder 33 and the shoulder 4l engages the projection 35.

In a latch for refrigerator doors or the like, a. casing adapted to be mounted on the door, a bolt slidable in the casingr and having a. roller on its free end, a spring lor projecting the bolt, a pivoted tripping meniber mounted in the casiner and having a projection extending from the casing. means for moving the tripping' device into engagement with the holt to hold the holt retracted and to limit. the projection thereof. a bell crank pivoted in thc casing,r and operatively eonnected with the bolt, a lever pivoted on the easing' and havingr an arm to engage the hell crank for retracling the bolt when the lever is moved on its pivot to open the door, .f keeper adapted to he mounted on the door frame and havin;t a beveled portion to engage the holt roller when the holt if pro jccted to hold the door closed, and a plato portion to engage the jn'ojection ot the trippinfdr device ivhen the door is' moved to clof-t-fl position for releasing` the tripping' device, from the bolt to permit automatic projection thereol' behind the keeper ivlierebj7 the door if; held closed.
i2. A latch comprising; a easing. a bolt in the casing, means lor projecting the holt. ar bell crank lever actuating member pivotc'l in the casing. one arm oi which engages the bolt. a handle for actuating the bolt connected to the other arm ot the bell crank lever, said holt provided with epaced nfiitehea. a tripper adapted to engage in either ot .said notches, means for urgingr the tripper toward the bolt to engage the same in the notches. said tripper provided with a member extendingy out from the casing, and a keeper in which said bolt is adapted to engage and againstvvhich said tripper is adapted to conW tact to move the same to release the bolt.
3. A latch comprisingY a casing, ay bolt in the casing, means for projecting the bolt, a bell crank actuating member, said bolt provided with a pin, one arm of' the actuating lever engaging the pin, a handle for ecuating the holt pivotaily engaging the other arm oit' the lever, said boit provided with spaced notches in one edge thereof, a tripper adapted to engage in either of the notches, spring means for urging the tripper toward the bolt to engage the same in the notches, said tripper provided with a member extending out from the casing below the bolt, and a keeper in which said bolt is adapted to engage, said ykeeper provided with an outstanding member lagainst which the said tripper is adapted to Contact to move the same to v release the i holt.
