    Abstract: 1,100,515. Rocket launcher. NORRIS INDUSTRIES Inc. 1 June, 1966, No. 24520/66. Heading F3C. A rocket launcher comprises telescopically connected first and second sections, the first section having at one end the breech and being housed, in the inoperative position of the launcher, within the second section. The first section is provided with a rigid member 26 of channel section overlying the second section and, when the sections are extended to the operative position of the launcher, moves relative thereto. The member 26 has attached thereto a spring-loaded latching member 51 which keeps the sections locked either in the inoperative or operative positions of the launcher (Figs. 1, 2, not shown). The first section also includes a firing member 28 comprising a spring-loaded firing pin 29, the firing member 28 being, in the inoperative position of the launcher, connected to the rigid member 26 by a spring latch 34 engaging in apertures in both members and held in position by a sleeve like lock 35. The second section is provided with a firing mechanism which includes a pivoted, spring-loaded trigger 37 associated with a slidable safety device 45 and trigger sears 42. On extension of the two sections the members 26, 28 move together relatively to the second section until a depending stop 51 attached to the second section urges the lock 35 away from the latch 34 and the trigger sears 42 engage laterally projecting shoulders of the firing member 28. Further extension of the two sections causes the rearward edge of the retaining aperture of the member 28 to engage the rearward end of the latch 34 and cam the latch upwardly thus disconnecting the two members. The firing member 28 is thus cocked by the final relatively short movement of the two sections. The safety device 45 when urged away from the trigger 37 in the operative position of the launcher has a portion which is engaged by the latch 34 to lock the safety device in its inoperative position (Fig. 6, not shown). In the inoperative position of the two sections a foresight 55 and a rear sight 58 of the second section are kept in a depressed state against spring loading by the latching member 51 and a housing 18 of the first section.

    Abstract: 1,098,118. Sights for weapons. NORRISINDUSTRIES Inc. April 4, 1966, No. 14977/66. Heading F3C. A sight for a weapon comprises a mount 14 and a sighting unit housed within the mount and including a vertically movable sight member 22 to which one end of a thermally responsive means 24 is connected. The other end of the thermally responsive means 24 is connected to the mount and is made of such a material, e.g. bi-metallic strip, that in the case of a back sight, the sighting member is lowered in the mount for a decrease in temperature and raised for an increase in temperature. The sight is for a weapon firing rocket having solid fuel propellent, the efficiency of the propellant depending upon its initial firing temperature. Hence as the propellant temperature increases the trajectory of the associated projectile becomes lower, the sight compensating for this energy variation (Fig. 1, not shown). The thermally responsive means may comprise a helix formed from helically wound bi-metallic strip, a spiral bi-metallic strip (Fig. 6, not shown) on a U-shaped bi-metallic strip one end of which is connected to the mount and the other end carrying a forked member, a pin, joining the free end of the forked member, working in a diagonal slot in the sight member (Fig. 7, not shown). The sight member 22 is provided with a peep aperture 23 viewed through windows 21 in the mount. The thermally responsive means 24 is a free fit within a sleeve 26 of heat reflecting material such as aluminium.

    Abstract: A resilient sleeve is provided as an accessory to enclose the space around a tubular type door lock mechanism mounted in a hole bored through a door. The diameter of the sleeve is normally larger than the diameter of the bore so that after being contracted and a pair of lugs are projected under the edge of the trim on one side, the sleeve will expand to the interior size of the bore and at the same time the lugs will engage beneath the edge of the trim.

    Abstract: INNER LOCKING CYLINDER WITH CAPTIVE KEY A dead bolt lock set is designed to be key actuated on the inside as well as on the outside of the door For the inside there is an inside tailpiece in engagement with a drive slot in the dead bolt hub. A lost motion circumferential recess on the inside tailpiece provides stops at positions such that when the key is inserted on the inside and turned to lock the dead bolt by action of a micro drive pin, the key cannot be returned in reverse direction to key release position without unlocking the dead bolt. Consequently, the key must remain captive in the inside keyway to keep the dead bolt locked because of being held in the cylinder by the pin tumblers. When the lock has been locked from the outside, the drive slot in the head of the tailpiece is rotated out of line with the inside key slot. Under this condition when unlocking from the inner trim, the tailpiece and washer are forced inward by the key tip compressing the conical spring and allowing full key insertion. Bolt retraction (unlocking) may be accomplished by rotation of the key in the bolt extended direction until the key tip aligns with the tailpiece drive slot, then rotating the key back to the vertical (withdrawn) position, or, in the alternative, rotating the key in the retract direction, whereby the micro pin contacts the lost motion stop on the tailpiece head thereby driving the mechanism to the retracted position. The captive key mechanism is fail safe in that in the event the conical spring fails to return the tailpiece to a position abutting the end of cylinder plug for captive key operation, the mechanism will still function as a standard cylinder allowing normal locking and unlocking.
