Title: Improvements relating to locks
Inventor: WHITEHURST LAWRENCE
IPC: E05B27/08
Filed: 1958-12-19
Abstract: 940,428. Locks. LOWE & FLETCHER Ltd. Dec. 18, 1959 [Dec. 19, 1958], No. 41107/58. Heading E2A. A lock comprises a spindle 4 incorporating a barrel 5 and rotatably mounted in a casing 1, the barrel being releasably locked to the casing by a plurality of slidably-mounted, spring- loaded pins 3 which engage both the barrel 5 and a bush 2 secured in the casing 1, the pins 3 being displaceable by thrust pins 6 when these are moved by a key 9, to a position in which the pins are removed from engagement with the barrel to free the latter for rotation, the pins 3 having portions of reduced cross-section where they pass through openings 29 in a guard member 8 so as to provide axially presented shoulders 34 and clearance with respect to the openings 29, whereby movement of one only of the thrust pins 6 and its associated pin 3 to the latter's unlocking position with application of torque to the barrel 5 produces misalignment of the openings 29 with respect to the pin bores 28 in the barrel 5 and skewing of the remaining pins 3 in their bores, so that portions of the guard member 8 bordering the openings 29 are brought into the path of the shoulders 34 on the remaining pins 3 to prevent these from being removed from the barrel 5. The thrust pins 6 are retained within the casing 1 by a flange 7 on the latter. Rotation between the guard member 8 and the barrel 5 is limited by a lug 32 on the member engaging a slot 12 on the barrel. A spring-loaded rocker 11 is pivotally mounted at 13 on the spindle 4 and is adapted by means of lugs 14 and 18 respectively either to further lock the barrel 5 to the casing 1 when the key 9 is withdrawn from the lock and the pins 3 are in their locking position, or to retain the key in the lock when the key has been turned to rotate the barrel, the rocker being moved against its spring-loading to disengage the lug 14 from a slot 15 in the bush 2 and to engage the lug 18 in an opening 19 in the key shank 10 by the end of the key engaging a lug 21 on the rocker when the key is inserted into the lock. The key 9 is located in the lock by means of a web 20 on the key engaging a slot 37 in the spindle 4, the web and slot engagement serving to drive the spindle when the key is turned. A further slot similar to but angularly spaced from the slot 15 may be provided to permit removal of the key from the lock in a second position of the key. A hinged cover plate 24 is provided to close the casing upon removal of the key from the lock. Specification 940,429 is referred to.

Title: Wheel speed sensor
IPC: G01P3/44
Filed: 1974-09-25
Abstract: 1472789 Rotational speed sensor KELSEYHAYES CO 25 Sept 1974 [23 Nov 1973] 41652/74 Heading G1N A speed sensor 10 for providing an electrical signal representative of the relative rotation between two members comprises a stator 38 having a first surface 100, a rotor 24 for mounting on one of said members and having a second surface 32 confronting the first to provide a magnetic path therebetween having a reluctance which varies with relative rotation of the rotor and stator, e.g. due to circumferentially distributed openings (34), Fig. 2 (not shown), in the rotor 24. A magnet 74 is associated with the magnetic path to provide the necessary flux, and a coil 68 provides the electrical signal. Mounting means 40 is provided for mounting the stator 38 on the other member, and includes a resilient member 44 which supports the stator 38, at two spaced locations, in such a way that initial abutment of the first and second surfaces 100, 32 allows, upon rotation of the rotor 24, the surfaces to move apart in response to engagement thereof e.g. due to eccentricity of the member on which the rotor is mounted. Thus a minimum spacing of the surfaces is automatically achieved, the means 40 maintaining the spacing due to the friction between the resilient member 44 and the stator 38. The stator 38 may have circumferential grooves 58 to increase the friction. The resilient member 44 may be fitted within a housing having dimensions causing inward bowing of the member 44 which results in the sensor being gripped with increased force at two spaced locations. Alternatively, the resilient member may be provided with end flanges joined by an axially extending radial rib to provide spaced gripping locations.
