The4 shifting mechanism for thc sliding latch bolt 16 includes the formation lof a socket 19 opening'at the endV of the bolt shank '16` Vcarried, by a band 21 is received. Av sleeve 22 is rotatable in the bandl 21as shown' in Figs. 1 and 3 and has van inwardly directed block projection 23 the inner edge of which is provided withV a cylindrical socket 24 communicating with a restricted passage 24 openingin the center ofthe cylinder 22. A knob spindle 25'shown in'detail in Fig. 7l carries a longitudinal lug 28, the spindle 25 Y extending into the socket 24 in the cylinder block 23 with the lug 26 projecting into the restricted opening 24 of the cylinder block as shown in Figs. 1 and 3 to cause the cylinder to rotate withthe spindle v25.
posite ends of the spindle project through opposite sides of the door 1 as shown inFig. 2 and a knob 27 attached to each end thereof, each knob being of two-part construction as shown in Fig. 7 and secured together by the pin 28, the sections of the knob inclosing the spindle extensions 29. Y
A device is provided for retaining the sliding latch bolt 16 in its locked position, guide flanges 30 being provided upon the bottom wall of the lock casing and receiving a sliding frame 31 having a longitudinal slot 32 through which a transverse pin 33 extends tov maintain the member 31 in position. One end of the sliding member 31 hasan angular upstanding arm 34 projectingbeyond the key receiving opening in the side of the casing and with which the key is adapted to be engaged for shifting-the sliding member 31. A pin 35 extends transversely of the casing adjacent the opposite end'of the sliding member 31 and supports aA journaled sleeve 36 carrying a depending arm 37 having at the lower end thereof a pin 38 extending into the slot 32 of the sliding member while a curved latch arin 39 is carried by the sleeve 36 and extends upwardly therefrom and passes through a guide bracket` 40 secured to the -side wall of the casing 3 with the nose 41 of the latch arm extending through an opening in an angle extension 42 carried by the lower end of the bracket 15, a coil spring 43 surrounding the latch rod between lthe guide bracket 40 and the angle extension42 of the bracket 15 normally to hold the nose 441 of the latch at the limit of its forward movement. The
lower face of the sliding latch bolt 16 is f projected with a recess 44 defining an abutportion 47.
ment shoulder 45 against which the flat face of the latch nose is adapted to engage and limit the forward projecting movement of the sliding latchbolt` as influenced by the spring 17.
A key of the type shown in Fig. 8 is employed for releasing the latch device from the outer side of the door 1, the key comprising a handle 46 having a shank including a straight blade section 47, a right angular o'set 48 at the lower .end thereof and.
an inclined blade portion 49 extending from the offset 48 having the lower end thereof substantially in alinement with the blade An escutcheon plate 50V is secured to the outer face of the door 1 and carriesa disk 51 rotatably mounted therein adjacent the lower end with an opening 52 therein corresponding to the key plate in An escutcheon plate 53 lis carried by the inner face of the door and The ophas a disk 54 rotatably mounted therein adjacent the lower end and is provided with a slot 55 havingan end offset portion 56 for receiving a similarly shaped key, the slots 52 and 65 in the disks 51 and 54 respectively are alined with each other through the lock casing 3 and extend inwardly of the angle arm 24 carried by the sliding 'member'31 for operating the latch* device.
In the operation of the device, assuming that the sliding latch bolt 16 is in the position shown in Fig. 1 projected through the opening 13 in the casing wall 7 and into the the key employing the relatively angular` blade portions 47 and 49 is inserted in the key slot 52 of the -disk 51 with the inner end thereof positioned inwardly of the angle arm 34 of the sliding latch operating member 31. By rotating the key 46 to the position shown in Fig. 3., the blade 49 of the key engages the angle arm 34 to shift the sliding member 31 guided by the pin 33 and the guide 34 to rotate the sleeve 36 upon the shaft 35, moving the arm 37 to the sleeve and the curved latch arm 39, thereby lowering the latch head 41 from engagement with the sliding latch bolt 16 at which time the knob spindle 25 will be rotated to shift the ring 22 within the sleeve 21 effected by the lug 26 of the knob spindle lockfing the spindle to the block 23 of the sleeve 22. 1totation of the spindle will cause` a translating movement of the ring 21 and the connection 19 and 2O between the sleeve and latch bolt will withdraw the latch bolt against the tension of the spring 17 to the position shown in Fig. 3 to free the projected-end of the latch to remove the projected end of the latch from the keeper socket 5 in the door frame, at which time the door may be swung to an open position. The key 46 may then be removed from the slot 52 and the upper end of the latch head 41 will engageV the lower face of the sliding latch bolt 16. 1n locking the door, the sliding latch bolt 16 is reversely shifted to the projected position shown in Fig. 1 by rotation of the knob spindle 25 to positionl theV notch 44 in the lower end of the latch bolt for reception of the latch head 41, the spring 43 elevating the latch head to automatically lock the door. To release the lockmechanism from the inner side of the door, akey conforming to the shape of the slot 55 shown' in Fig. 6 is employed with the inner end thereof positioned for engagement with the angle arm Y 34 of the sliding member 31 andthe operation by rotating the key is the same as above described.
