Title: Improvements in Locks and Keys therefor.
Inventor: HACKETT ERNEST AUGUSTUS
Filed: 1908-07-16
Granted: 1908-11-19
Abstract: 15,084. Hackett, E. A. July 16. Locks, key; keys; keyholes, obstructing.-The key pin 2 of a lock is formed hollow and is provided with a pivoted bell-crank 7, one arm 6 of which is normally pressed outside the pin by means of a spring 4 and thereby prevents the full insertion of a false key. The proper key 3 is provided with a rod 10 within its barrel which, when the key is inserted, passes through a fixed disk 9 at the top of the key pin and presses a movable disk 8 inwards, the aperture 12 being too small to allow it to pass through. The strong spring 5 is thereby compressed, and the bell-crank is withdrawn until the arm 6 is flush with the side of the key pin, after which the key can be fully inserted and turned. In the modification shown in Fig. 3, the pin 10 and the apertures 11, 12 in the disks are eccentric, and the disk 9 is rotatable, a spring pin 14 determining its normal position. In another modification the disk 9 is also pressed in by a projection on the rod 10. A form is described in which the end of the arm 6 of the bell-crank is formed with a knife-edge to cut a key pressed against it, the keyhole being arranged so that only a key with a thin metal barrel can be inserted. The key pin may be extended beyond the lock plate 1 to provide more room for the spring 4. The key is provided with a spring plunger to keep the barrel clear of the dust and to steady the pin 10, and the keyhole may have closing. shutters 20, Fig. 12, embedded in the woodwork and adapted to be pressed apart by the key.

Patent GB-190818715-A (GB)
Title: Improvements in or relating to the Regulation of Alternating-current Electric Generators Working in Parallel.
Filed: 1908-09-07
Granted: 1909-05-20
Abstract: 18,715. Siemens Bros. Dynamo Works, [Siemens-Schuckertwerke Ges.]. Sept. 7. Distributing.-To obtain constant potential and to avoid the setting-up of equalizing currents between alternating current generators working in parallel, assuming that the power factor of the load is constant for considerable intervals of time, the regulation is effected by means of relays having two distinct windings carrying currents proportional respectively to the generator current and terminal pressure, and an adjustable phase converter is connected in circuit with one of these windings. In a three-phase arrangement, Fig. 1, the field magnet windings e<1>, e' of the generators I, II are fed by continuous-current machines g<1>, g<2>, in the armature circuits of which are arranged resistance switches a' rotated in one or the other direction by auxiliary motors m having two separate exciting windings m<1>, m' controlled by relays r<1>. Each relay r<1> has a current winding z<1> fed by a series transformer t<1>, and a potential winding s' fed by the secondary winding of a rotary phaseconverter u<1>, the primary of which lies across the generator terminals. By adjusting the handle k, the current in the coil s<1> may be given any desired phase relation with respect to the potential of the mains, so that the effective ampere-turns on the relay r<1> may be varied. The phase-converter u<1> may be placed in circuit with the coil z<1>, the winding s<1> being then connected directly across two of the generator terminals, and, in place of the motor m and the switch a', either of the generators I, II may have its field-magnet circuits controlled by a quick-acting regulator, such, for example, as that described in Specification No. 14,725, A.D. 1907. The arrangement described above should be supplemented-by a bell signal or the like, so that the phase converter u<1> may be adjusted if the power factor of the circuit should vary.
