Abstract: 1,160,421. Reels; take-up and release mechanism; winches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 17 Nov., 1966 [9 Dec., 19651, No. 52345/65. Headings B8B and B8M. [Also in Division F2] A take-up and release mechanism for a flexible linear member e.g. wire rope, wound on a rotatable member comprises a locking member movable between a first position which prevents rotation of the rotatable member to unwind the flexible member, and a second position in which the rotatable member is free to rotate, the movement of the locking member being by way of an electrical device. In a preferred embodiment, the rotatable member is a drum 1 having wound thereon a wire rope 5, a handle 7 being provided for rotating the drum to wind the rope 5 on to the drum. Secured to the spindle 11 of the drum there is provided a ratchet wheel 9, the teeth of which are engaged by a pawl 15. The pawl 15 constitutes the locking member which is brought into and out of engagement with the ratchet teeth by an electrically operated system. The electrically operated system, Fig. 3 (not shown) comprises an electromagnet (23) controlling a pivoted L- shaped armature (25), one arm of which engages a bell crank lever (29) which bears against a curved lever (19). Secured to the lever (19) and pivoted at the same point is a lever (39) one end of which bears against a rod carrying the pawl. The curved lever (19) is spring biased to maintain the pawl out of engagement with the ratchet teeth. Upon energization of the electromagnet (23) the armature (25) is pivoted to move the bell crank lever (29) out of engagement with the curved lever (19). The curved lever (19) pivots thus pivoting lever (39) to depress the rod carrying the pawl which is pivoted out of engagement with the ratchet. Movement of the lever (39), Fig. 1 (not shown) may actuate a switch (53) to sound an alarm. In a preferred embodiment the take-up and release mechanism is used to open a weighted tap to supply water to a sprinkler device in a mine in the event of a fire, the actuation of the mechanism being in response to a temperature sensing device.

An electrical lock device comprises an electro-magnet 19, an armature portion 16 of which is movable between first and second positions, a_spring 17 urging the armature portion from the first towards the second position, movement of the armature portion from the second to the first position being effected by energisation of the electromagnet 19 to retain the armature portion 16 in the first position when the energising current is reduced to zero, the device being in a locking condition when the armature portion is in one of its positions and being in a non-locking condition when the armature portion is in the other of its positions. As shown, a bolt projecting from an edge of a door, is engageable with a cam 2 mounted on a pivot pin 6, the cam being retained in the position shown by a lever 8, which acts upon a slide 7 and by an L-shaped lever 13, one end 15 of which bears on the lever 8 against a spring 17 and the other end 16 of which constitutes the armature portion of the electro-magnet 19. When the electromagnet is energised through contacts 26, 26', the lever 8 is freed and the door may be opened. If the electromagnet is then disconnected from the power source, the armature is not released due to residual magnetion of the cores 20 and the door can only be relocked by opening movement of the door, followed by a closing movement thereof which moves the lever 13 through a lever 18 away from the cores 20 or by energising the electromagnet through contacts 27, 27' after the lever 18 is raised from the position shown, which effects de-energisation of the cores 20 and movement of the lever 18 directly by the spring 17. In another arrangement, Fig. 4 (not shown), the L-shaped lever normally blocks releasing movement of a spring-released sliding bolt and the electro-magnet is energised to release the bolt through a normally closed switch at the door edge which opens to disconnect the electromagnet when the door is open, energisation of the electro-magnet being effected by unidirectional current and denergisation by alternating current.
