Abstract

790,415. Latches. DEXTER INDUSTRIES, Inc. March 26, 1956 [March 28, 1955], No. 9306/56. Class 44 An alternate-handed latch comprises a housing 10, 11, a front plate 16 rotatably mounted with respect to the housing and having an aperture, projecting means 34, 35 and 36, 37 on the housing extending towards the axis of the housing and disposed to provide axially-spaced abutments, a plate 30 received between the abutments for rotation with respect to the housing, a bolt 24 slidably received in the front plate aperture and having a stem 28 extending rearwardly, key means for maintaining non-rotative relationship between the bolt and the plate, and retracting means including a link 48 rotatably connected to the bolt stem. As shown, the two parts of the housing are held together by means of a locking plate 17, ears 18 and 19 of which engage apertures in the housing sections, and by a rotatable sleeve 13 which is secured to the front plate 16: Detents 20 and 21 engage corresponding apertures in the body portions 10 and 11 when the sleeve and thus the bolt is rotated to one of two positions 180 degrees apart. A deadlocking bolt 23 is slidable with respect to the bolt 24 and carries a plate 25 forming part of a dead locking mechanism, such that when the bolt 24 is shot as the door is closed, the bolt 23 is retained between the lock keeper and the front plate 16 and any attempt to force the bolt 24 by means of an instrument inserted between the door and its jamb, swings a member 26 pivoted to the bolt into engagement with the side of an opening in the plate 30 through which the stem 28 and member 26 normally slide. The bolts 23 and 24 are located with respect to the plate 30 by a pin 31 on the plate 30 which engages the bolt 23 and by a rod 33 on the bolt 24 which slidingly engages the plate 30. The link 48 is formed with an opening 50 which receives and retains the end of the bolt stem 28 and is of such shape as to permit relative rotation of the stem and link while still retaining engagement. Specification 790,414 is referred to.
