Title: Improvements in and relating to Electrical Switches.
Inventor: TREHERNE JOHN WILFRED
IPC: H01R13/71
Filed: 1916-06-29
Abstract: 107,259. Treherne, J. W. June 29, 1916. Plug couplings combined with electric switches. The device is of the kind wherein the plug can be introduced into and removed from a rotatable contact-carrying socket only when these contacts are disengaged from the fixed contacts, the plug being locked in position when the contacts are engaged, and the socket locked when in the " off " position so that it cannot be turned until the plug is inserted. According to the invention, the base 1 is provided with an upstanding central projection 3 formed with a rim 4 which is engaged by notches 18 in the plug pins 17, so that, when the plug 16 and socket 6 have been turned together from the " off " position, the plug cannot be withdrawn from the apparatus. The socket contacts 11 are adapted to engage with fixed contacts on the base between an outer rim 15 and the projection 3, a cover 14 being arranged to embrace the socket closely. Spring plungers 8 engage with the holes of the socket to prevent it from being turned until the plug is introduced; as the plug is inseited, its pins depress the plungers clear of the socket, and the plungers then ride up inclines on the bottom of the socket as the plug and socket are being turned to close the switch. A bifurcated spring in the socket engages with the faces of a square nut 13 and so prevents the socket from occupying a position intermediate to the " off " and " on " positions. According to the Provisional Specification the plug pins may be locked by a pin, catch, pawl, &c., and the plug may have pins additional to the contact pins for taking the strain as the plug and socket are turned.

Title: Improvements in or relating to timing devices
IPC: G04C3/06
Filed: 1942-07-07
Abstract: 557,402. Time switches; egg-cooking apparatus. TUTTLE, H. C. July 7, 1942, No. 9434. Convention date, July 10, 1941. [Class 38 (v)] [Also in Group VI] A timing suitable for incorporation in an egg-cooking machine comprises a shaft, a driving gear secured to the shaft, a driven gear carried by a coupling member movable between inoperative and operative position to engage or disengage the gears, means for adjusting the angular position of the driven gear to a preselected timing position whilst the gears are disengaged, hand-operated mechanism for moving the coupling member to operative position and means for automatically returning the coupling member to inoperative position after lapse of the predetermined time. As applied to an eggcooking machine provided with two cooking units each having a rotatable cover 14 to admit or shut off cooking steam, the closure of a cover (for example, the right-hand cover) by means of its knob 57 rotates a shaft 23 in the direction of the arrow 56 shown in Fig. 2. A detent 25 on the shaft engages a notch 36 in a spring- pressed lever 34, and a finger 26 pushes back a lever 46 to close a motor contact 54 and start the motor. The lever 46 also resiliently displaces a pivoted plate 43 bearing a gear wheel 20 which is thus engaged with a gear wheel 18 driven by the motor. The motor acting through the gears 18, 20 drives a timing gear 38 until a pin 40 displaces the lever 34 and allows the detent arm 24 to return to the position shown, at the same time opening the cover 14 and breaking the motor circuit. The liberated lever 46 and its resiliently connected plate 43 are also returned by a spring to remove the gear 20 from engagement with the gear 18. The duration of the cooking period is determined by adjusting the initial position of the pin 40 whilst the gears 18, 20 are uncoupled, the adjustment being effected by rotating a time-indicating knob secured to the shaft 16 on which the pin is carried. Reference has been directed by the Comptroller to Specification 542,676.
