Definitions

a lock according to the invention comprises a casing 1 to one side of which is mounted an inner forend 3 and an outer forend 4 (not shown in Fig. 1).
the casing is arranged to be closed by a cover plate 2.
a latch bolt assembly is reciprocally mounted in the casing and comprises a latch bolt head 5 secured to a latch bolt lath 6 by screws 7 which engage in screw-threaded bores 6a in the bolt lath 6.
the latch bolt head 5 is urged by a spring 8 to project through an aperture 4a in the forends 3, 4 under normal conditions, the spring bearing at one end on a wall 6a of the lath 6 and at the other end against a side wall la of the casing 1.
the spring 8 is held in position by engaging pegs 9a and 9b fixed, respectively, to the wall 6a of the lath 6 and the side wall la of the casing 1 and engaging in the respective ends of the spring 8.
the lath 6 is guided for sliding movement in the casing 1 by a pin 10 which is fixed to the casing and extends through an elongated aperture 6b in the lath 6.
the arm 11a of a follower 11 is located between the pin 10 and the wall 6a of the lath 6, the follower being mounted on a square-sectioned spindle (not shown) extending through the casing and having a handle (not shown) fixed to at least one of its ends.
Aligned keyhole slots 1c and 2c are provided in the casing 1 and cover plate 2 respectively and a bolt thrower 20 is rotatably mounted in the circular parts of the slots lc and 2c.
a cam controller 21 is pivotally mounted on a pin 23 in the casing 1 and is arranged to be acted on by a spring 22 which is mounted on a pin 28 in the casing.
the spring 22 urges the cam controller 21 into engagement with the bolt thrower 20 so that the bolt thrower engages in a notch 21a in the cam controller whereby the bolt thrower is held in position in the unlocked condition of the lock as shown in Fig. 2 of the drawings. Also as shown in this figure, the deadbolt 15 is fully withdrawn in the unlocked condition of the lock.
the extension lever 18 is so located that as it is driven at its edge 18a by the face 20a of the bolt thrower 20, as the latter rotates, an effective straight line "throw" of 17mm is generated by the arcuate path of the edge 18a as it is propelled across the sweep of the rotating bolt thrower 20.
the effective straight line dimension between the edges 18a and 18b at the commencement of the action in the unlocked position is 11mm but since the angular relationship between the points of contact at 18a and 18b changes as the extension lever pivots on the pin 19, in the fully thrown i.e. locked condition, the effective dimension between the edges 18a and 18b becomes 14mm. This increase of 3mm when added to the 17mm already provided by the extension lever 18 results in 20mm of motion being imparted to the deadbolt.
Fig. 12 shows the deadbolt 15 in the fully withdrawn position with the angled face 15c on the deadbolt engaging the radiussed face 20b of the bolt thrower 20 and, since the guide pin 17 on the deadbolt has reached the limit of the slot 16 in the casing, the deadbolt is held in this position while the bolt thrower continues to rotate in a clockwise direction.
the detainers 24 are released from the lifting steps of the key and, under the action of the springs 25, they pivot in a counter-clockwise direction until the notches 24b in the slots 24a engage with the detent block or stump 16 thus holding the deadbolt in its fully withdrawn or unlocked position.
the cam 40a has the same effect as the bolt thrower 20 in the detainer version, in that when throwing the deadbolt from the unlocked to the locked position the cam 40a acts against the edge 38a of the extension lever 38 and an edge 38b of the extension lever acts against a shoulder 36a on the deadbolt head 35a.
the cam 40a of the cylinder is rotated further counter-clockwise, as viewed in Fig. 14, the extension lever is obliged to pivot further clockwise and the changing geometry between all the points of contact delivers the required increased amount of leftward travel to the deadbolt, just as in the detainer version.
the deadbolt assembly again incorporates a detent block or "stump" 36 but since the "differing" of the system is now a function of the pin-tumbler mechanism, only a single detainer 44 is needed in order to arrest the deadbolt at each end of its travel.
the detainer 44 is pivotally mounted on a pivot pin 46 which is fixed in the casing, a spacer 47 being located between the deadbolt lath 35b and the detainer 44 and the spacer being similarly pivotally mounted on the pivot pin 46.
the latch bolt head 5 may be reversed in either or both of the above-described embodiments.
the bolt head is provided with bores 5a on both sides to accommodate the screws 7 for this purpose.
Apertures 2b in the cover plate 2 allow access to the screws 7 from outside the lock so that the casing does not have to be opened in order to reverse the bolt head.
