Patent GB-542299-A (GB)
Title: Improvements relating to door and like fastenings
IPC: E05B11/00
Filed: 1940-12-18
Abstract: 542,299. Door fastenings. LINES, A. Dec. 18, 1940, No. 17810. [Class 44] A lock particularly for the inner doors of houses has a key on each face of the door, the keys being permanently retained in the lock to prevent loss, and the lock mechanism arranged so that when the bolt is shot by either key, the other key is rendered inoperative. As shown, the bolt lath 1 has a lever 2 pivoted thereto at 3 and is cut away at 4 to allow upward movement of the lever. The lever is normally depressed by spring 6 against a fixed pin 5, is shaped to provide a pair of opposed shoulders 10, 13 and has a depending projection 7 adapted to engage the right or left side of pin 5 to lock the bolt. The two keys have their stems 8 in alignment and their bits normally in the position 16. The lever is wide enough to co-operate with both bits, and the bolt carries a projection 12 of similar width. In Fig. 2 the near bit 9 has been rotated anti-clockwise to shoot the bolt by co-operation with shoulder 10 after lifting the lever to move projection 7 clear of pin 5, and the lever has dropped to engage projection 7 to the left of pin 5 to lock the bolt in shot position. Rotation of the bit 9 is also arrested by pin 5. With the bolt thus shot, anticlockwise rotation of the other bit is arrested by projection 12, whilst pin 5 arrests clockwise rotation. A similar action occurs when the bolt is shot by bit 11, bit 9 being rendered inoperative. The bolt can therefore be retracted only by the key which shot it, its bit first lifting the lever to release projection 7 and then engaging shoulder 13. With a mortise lock as shown, the keys may be retained by forming the lock with keyholes 14 having horizontal extensions 15 to accommodate the key stems 8, the hole 14 being out of register with the position 16 of the keyhole in the door style. The lock is pushed into place till slots 14 register with 16, the keys are inserted, and the look pushed home to the final out of register position, the stems 8 passing along slot 15. To steady the motion of the key a plate 17 having a tubular bearing 18 for stem 8 is applied to the key before the bow 19 is secured to the stem. When the keys are in place, plates 17 are secured to the door by screws. With a rim lock, the casing may have circular holes through which the key-stems are passed from inside, the key bows being afterwards secured on the stems. Specification 502,369 is referred to.

Filed: 1953-06-29
Abstract: 725,409. Circumferentially adjustable couplings. GLEASON WORKS. June 29, 1953, No. 18012/53. Class 80 (2). Fine circumferential or other adjustment between two coupled parts, one of which may be stationary, such as a shaft 10 and gear-wheel 11 freely mounted thereon, includes a locking part 28 having two differently numbered sets of V- sectioned facial clutch teeth 29, 31 engaging complementary teeth 17, 27 on parts 13, 19 secured respectively to the gear-wheel 11 and shaft 10, together with toothed gearing, such as' a planet pinion 38 carried by the locking part 28 and meshing internally or externally toothed complete or segmental rings 16, 26 on the gear and shaft parts 13, 19 respectively, which gearing compels such relative rotation between the parts that in all positions where one set of clutch teeth will engage, the other will also engage. The essential condition for this is that the tooth number ratio of the sets of clutch teeth must be the same as or an integral multiple or reciprocal of such multiple of the toothed number ratio of the corresponding gear rings. As shown the tooth-rings 16 and 26, as well as the clutch sets 17, 29 and 27, 31, each have 100 and 102 teeth respectively, giving relative adjustment of 1/5100 of a revolution. To make an adjustment an endwise locating nut 32 is slackened back, permitting a spring to demesh the clutch teeth. If the gear-connected part 13 is now held and the locking part 28 rotated, the 18-toothed planet pinion 38 rotates the shaft-connected member 19 in the same direction at 51 to 1 reduction so that whatever integral number of clutch-teeth 17, 29 is advanced by the locking part 28 both sets of clutch teeth will register correctly when the locking part is again tightened by the nut 32. The device may be used in the gear-grinding machine described in Specification 689,037, [Group XXII]
