    • 211,995. Brookman, R. S., and Moss & Sons, Ltd., W. Dec. 11, 1922. Regulating.-A four-stroke engine using a variable combustion chamber to suit the volume of the air or mixture charge has the whole of the charge supplied by a pump during the suction stroke; the variation is accompanied by an alteration in the amount of water circulating through the cooling system, by an adjustment of the engine valves, and if two fuels are used by changing over from one to the other. An adjustable abutment 6 forming the cylinder head is connected by outside rods to an eccentric 10 on an adjusting-spindle 11; a second eccentric 23 on this spindle is connected to a hinged quadrant 20 in which moves the pin joining the pump rod 18 to a driving connecting-rod 21. The spindle 11 is turned through the gearing 45, 47 - - 50 and the clutch relay 52 - - 54 from the governor shaft 55 according to the movement of the governor. The eccentric 23 varies the position of the quadrant to give a variable pump stroke, this being zero in one limiting position. An arm 82 on the quadrant varies the position of a throttle valve 79 in the water-circulating system. Either petrol or paraffin are supplied through the three-way cook 34. A cam disc 46 on the spindle 11 has (i) a stop 73 for acting on linkage. 74 - - 77 connected to the governor muff so as to limit the working of the governor, (ii) a cam 70 for moving the fuel cock 34, and (iii) a cam 64 for moving the bell-crank 65 used to slide the valve cam 62 on the cam shaft 61; the bell-crank 65 is also connected by a link 69 to a crank 68 and catch 84. When the valve cam 62 is moved to bring a twostep cam 63 under the exhaust valve, the latter is held open on the normal compression stroke; as fuel is simultaneously cut off, the engine then works as a brake. The catch 84, during this period, holds the water throttle valve closed. The movement of the valve cam 62 can also be effected by hand from the rod 67 through the lever 68; this lever acts through the link 41 on a cam 40 for holding the fuel pump inactive. The rod 41 may be worked independently of the lever 68 to stop the fuel supply. In a modification, carburetted air is drawn through the pump, the rod 69 being connected to a throw-over valve which can be used to cut out the carburettor and connect the pump to the atmosphere.

    • 3783. Johnson, A. H., and Bircham, F. R. S. Feb. 18. Relays.-Consists in a relay for use in electric lighting, whereby, when the normal lamp partly or completely fails, it is cut out of the circuit and an auxiliary lamp automatically lighted. The current from the mains n, p passes round a circuit consisting of an eccentrically-mounted carbon disc g, a spring f normally resting on the disc, and an armature d, Figs. 1 and 5, then round an electromagnet m' and through the auxiliary lamp r. It also passes round a circuit containing an electromagnet m , and the normal lamp s. The armature d is given a bias in favour of the attraction of a pole-piece c, by adjusting its distance from the pole or by regulating the relative ampÞre-turns on the magnets m , m , so that the contact c, k is made when a current flows, thus lighting the lamp s, and breaking the circuit of the lamp r at the brush g. When the lamp s fails, the armature, no longer being attracted, swings over on us pivot e owing to the weight of the spring f, causing the contact f, g to be made and the lamp r to be lit. The magnet m is excited at the same time, and the contact a, o closed by the attraction of the armature to the pole-piece, thereby firmly closing the circuit of the lamp r, while owing to the breaking of the contact k , c, the lamp s is cut out of the circuit. When applied to an alternating-current circuit, the iron magnet core is laminated. The spring f may, in some cases, be adjusted so as normally to rest a slight distance off the carbon disc, thus only making contact through the resilience of the spring when the armature is released from the pole c. This construction is shown in Fig. 6, where a small weight V gives the necessary momentum and a spring x and a stop z serve to adjust the spring f.
